The Galaxy Metal Gear Box 3500SASP supports current SATA and USB 2.0 specifications. The unit does not provide support for eSATA connections and instead relies upon the standard SATA interface for operation. Galaxy does provide an adapter bracket to utilize an internal SATA header on the motherboard. A USB 2.0 connection is also included for near universal compatibility between personal computer systems.

Galaxy Metal Gear Feature Set

The Galaxy Metal Gear Box SATA/USB 2.0 series is available in a brushed Silver, deep red, or a flat black color scheme. The graphics scheme and included blue LED strips that have a tendency to light up a small room target an audience who like for their product to be noticed. Nothing wrong with that, but the unit might look out of place on desktops with traditional component designs.

GMG Inc. has recently introduced the Metal Gear Box II series that features a revised design and five different color schemes. Both designs feature the same electronics and layout so performance will be similar.

The 3500SASP enclosure does not include a cooling fan and instead relies on a combination of convection cooling and chassis conduction to cool the enclosed hard drive. It can be positioned either horizontally or vertically, but we found the vertical position reduced noise, vibration, and heat. Our only problem with this design was the flimsy mesh inserts that had a bad habit of bending with only a light touch of the fingers. We suggest handing the unit so your fingers stay on the front and back of the main covers.

The connections on the back panel are standard issue for this type of enclosure: a power plug that attaches to the external power brick, USB 2.0 and SATA connections, a switch to enable or disable the disco lights, er, blue LEDs, and a power switch. The unit does not allow simultaneous operation of the USB and SATA connections.

The process of installing the drive is straightforward. All it takes is the removal of the top cover that is accomplished by unscrewing the four thumb screws. Once the top cover is off, drop the drive into the bay, slide the drive forward so the connections are set, replace the top cover, and reinstall the thumb screws. Our only problem was needing a small screw driver to move and hold the LED power cables at the bottom right of the case while installing the drive.

A quick review of the PCB layout shows standard SATA data and power connectors, external ports, and the LED power cable setup.

The accessory kit has everything you need to attach the unit to a system with SATA or high-speed USB 2.0 ports. The included SATA connection bracket connects to an internal SATA port and is required to utilize the unit as an standalone external device. Of course, you could run a SATA cable directly from the unit to one of these ports if required.

We found the quality of the SATA cables to be lacking when compared to cables provided by the motherboard or storage companies but did not have any issues with them during testing. Although the specifications at the website state SATA 1.5Gb/s compatibility and a limit to 500GB drives, we had no issues with our SATA 3Gb/s drives operating at full speed or capacities up to 1TB.

Design and operation of an automatic transmission

In the 21st century. people tend not to strain once again. Therefore, more and more drivers are switching to automatic transmissions and choosing cars that require a minimum of participation from them. Yes, and auto manufacturers are slowly but surely robotizing cars, so pure mechanics will soon be only for connoisseurs.

Despite all the charms, the automatic transmission has one big drawback (actually, like the «mechanics») — they are complex. Few motorists dare to sort out the box on their own. Even fewer are those who decide to repair the automatic transmission on their own.

From what, what are automatic gearboxes made of

So, a classic automatic transmission consists of:

• torque converter. Consists of pump and turbine wheels, reactor;
• oil pump;
• planetary gearbox. In the design of gears, sets of clutches and clutches;
• electronic control system — sensors, valve body (solenoids + spool valves), selector lever.

Automatic transmission device

These are the basic elements and they are always the same.

Torque converter — in the automatic transmission, it performs the clutch function: it transmits and increases torque from the engine to the planetary gearbox and briefly disconnects the transmission from the engine to change gear.

Torque converter, diagram

The pump wheel is connected to the engine crankshaft, and the turbine wheel is connected to the planetary gearbox through the shaft. The reactor is located between the wheels. The wheels and the reactor are equipped with blades of a certain shape. All elements of the torque converter are assembled in one housing, which is filled with ATF fluid.

Torque converter

Planetary gear . Consists of several planetary gears.

Each planetary gear consists of a sun gear, a carrier with satellite gears and a ring gear.

Planetary gear

Any element of the planetary gear can rotate or block (as we wrote above, the rotation is transmitted from the torque converter).

Planetary gear diagram

To shift a certain gear (first, second, reverse, etc.), you need to block one or more elements of the planetarium. Friction clutches and brakes are used for this. The mobility of the clutches and brakes is regulated through the pistons by the pressure of the working fluid ATF.

Friction discs (clutch)

Location of clutches in automatic transmission

Electronic control system . More precisely, electro-hydraulic, because. hydraulics are used to directly shift gears (on / off clutches and brake bands) and block the gas turbine engine, and electronics are used to adjust the flow of the working fluid.

The system consists of:

• valve body. It is a metal plate with many channels in which electromagnetic valves (solenoids) and sensors are installed. In fact, the valve body controls the operation of the automatic transmission based on data received from the ECU. Passes liquid through the channels to the mechanical elements of the box — clutches and brakes;

Valve body

• sensors — speed at the box inlet and outlet, fluid temperature, selector lever position, gas pedal position. Also, the automatic transmission control unit uses data from the engine control unit;
• selector lever;
• ECU — reads sensor data and determines the gearshift logic in accordance with the program.

The principle of automatic transmission

When the driver starts the car, the engine crankshaft rotates. An oil pump is driven from the crankshaft, which creates and maintains oil pressure in the hydraulic system of the box. The pump supplies fluid to the torque converter pump wheel, it starts to rotate.

The vanes of the impeller transfer fluid to the turbine wheel, also causing it to rotate. To prevent oil from flowing back, a fixed reactor with blades of a special configuration is installed between the wheels — it adjusts the direction and density of the oil flow, synchronizing both wheels. When the speeds of rotation of the turbine and pump wheels are aligned, the reactor begins to rotate with them. This moment is called the anchor point.

How the gas turbine engine works

Next, the ECU, valve body and planetary gearbox are included in the work.

The driver moves the selector lever to a certain position. The information is read by the corresponding sensor, transferred to the ECU, and it launches the program corresponding to the selected mode. At this moment, certain elements of the planetary gear rotate, while others are fixed. The valve body is responsible for fixing the elements of the planetary gearbox: ATF is supplied under pressure through certain channels and presses the friction pistons.

How the clutch piston works

How does an automatic transmission shift gears?

As we mentioned above, automatic transmissions use hydraulics to engage/disengage clutches and brake bands.

The electronic control system determines the moment of gear change based on speed and engine load.

Each speed range (oil pressure level) in the valve body corresponds to a specific channel.

When the driver presses on the gas, the sensors read the speed and load on the engine and transmit the data to the ECU. Based on the data received, the ECU launches a program that corresponds to the selected mode: it determines the position of the gears and the direction of their rotation, calculates the fluid pressure, sends a signal to a certain solenoid (valve) and a channel corresponding to the speed opens in the valve body.

Fluid flows through the channel to the pistons of the clutches and brake bands, which lock the planetary gears in the desired configuration. This turns on / off the desired gear.

How the automatic transmission works

Gear shifting also depends on the nature of the speed increase: with smooth acceleration, the gears increase sequentially, with sharp acceleration, a lower gear will first turn on. This is also related to pressure: when you gently press the gas pedal, the pressure increases gradually and the valve opens gradually. With a sharp acceleration, the pressure rises sharply, puts a lot of pressure on the valve and does not allow it to open immediately.

Electronics has significantly expanded the capabilities of automatic transmissions. The classic advantages of hydromechanical automatic transmissions have been supplemented with new ones: a variety of modes, the ability to self-diagnose, adaptability to driving style, the ability to select a mode manually, and fuel economy.

Signs of the need to change oil in automatic transmission, gearbox and MKPP

Few car owners know that the gearbox is the most stable part of their vehicle. This structural component of the car fails quite rarely, compared with other elements, but this fact does not mean at all that the gearbox does not need proper care and maintenance. Like all other parts of a car, manual and automatic transmissions tend to wear out and wear out. In order to avoid problems with this element of the car, it is recommended to systematically change the oil in the gearbox. The optimum level of lubrication for shafts, gears and other internal structural elements of the gearbox can be provided by high-quality gear oil. The friction force acting on all components of the car structure during its movement is accompanied by thermal effects, which, with frequent use of the car, leads to a decrease in the protective functions of the gearbox additives. This, in turn, as the parts wear, leads to the fact that small metal particles from the body of the structure can come off and enter the lubricating fluid. In addition, there is a risk of some water getting into the oil, which can also adversely affect its characteristics. The end result of the described process may be that at the most inopportune moment for you, it may be necessary to urgently change the oil in an automatic gearbox or in a manual gearbox.

The need to change the oil in an automatic transmission (automatic transmission): signs

speed. The main signs of the need to change the oil in the gearbox include:

• a visually noticeable change in the color of the oil. Used oil is opaque and dark in color;
• the presence of a burning smell, which indicates that the automatic transmission has constantly undergone an overheating process;
• foam or bubbles in the liquid indicate that the oil used is not suitable for this manufacturer’s box;
• automatic transmission malfunctions, for example, untimely gear changes.

A change in the state of the oil during the active operation of the vehicle leads to the fact that most parts of the automatic transmission eventually wear out and become unusable, and the box itself begins to work with noticeable interruptions. In the event that the owner of the car is a fan of high speeds and regularly travels long distances, then it is recommended that he check the machine box as often as possible for the need to change the lubricant, since the estimated mileage is 25 — 40 thousand km. Changing the oil in an automatic transmission, the price of which largely depends on the brand of the car, is best done at a car service, for the reason that an incorrect oil change can lead to a complete breakdown of the gearbox.

The need to change the oil in a manual transmission (manual transmission): signs intensifying when shifting gears;

The design of a manual transmission is much simpler than automatic transmissions, and the oil in it acts as a working fluid, while reducing the sensitivity of the elements to its quality level. Compared to an automatic transmission, a mechanical one is subjected to somewhat greater loads. The reason for this is the constant impact on the shift lever of the physical forces of the driver, which are not always stable.
