Automatic transmission is easy to use, driving comfort, reduce driver fatigue strengths, has become a modern car targeted a direction for development. Equipped with automatic transmission vehicles according to road conditions variable automatic transmission moment, drivers can watch with rapt attention to road traffic and not do a shift Shoumangjiaoluan.

Automatic Transmission There are three common types: hydraulic automatic transmission are sweet (AT), non-mechanical-automatic transmission (CVT), electronically controlled mechanical automatic transmission (AMT). At present the widespread use of cars is AT, AT almost become synonymous with automatic transmission.

AT variable-twisting by the hydraulic, gear and hydraulic control system components, transmission and hydraulic gear through the combination of methods to achieve variable speed moments. One variable hydraulic AT-twisting is the most important components, it round by the pump and turbine components, such as round and derivative components, both off and the transmission of torque.

Automatic Transmission Shift

Generally speaking, the automatic transmission into the Shift P, R, N, D, 2,1, or L, and so on.

P (Parking): used for parking purposes, it is using mechanical devices to lock the rotation of the vehicle, the vehicle can not be moved. When the vehicle needs in a fixed position on the stay for a longer period of time, or in parked vehicles * after leaving before the players should pull brake and Bogan will promote the "P" position. It should be noted that: vehicles must be completely stopped when the use of P block, or else automatic transmission mechanical parts will be damaged. In addition, the automatic transmission cars - [device activated switch in neutral gear, the car can only be made in the "P" or "N" to start the engine block, to avoid errors in other Shift on when the car suddenly started channeling ago.

R (Reverse): Reverse Gear, reversing vehicle use. Usually allocated according to the insurance rod button, Bogan will be moved to the "r" block. It should be noted that: When the vehicle has not been completely stopped time, and must not be forcibly transferred to the "r" block, or transmission would be seriously damaged.

N (Neutral): neutral gear. Bogan will be placed in "N" on the block, between the engine and transmission has been cut off from power. Such as a brief stopover at Bogan can be placed in this block and pull-hand brake, his right foot can be removed from the brake pedal a short break.

D (Drive): forward block, used in general road traffic. States have different models because of the design, "D" block generally includes high block from a block or two block high block, and because of changes in speed and load automatically shift. Bogan will be placed in the "D" block, the motorists to control the pace as long as the speed control can be good on the accelerator pedal.

2 (Second Gear): 1 block to block progress, but only in a block transmission, transformation between the two guards, will not jump to block 3 and 4 blocked. Bogan will be placed on Shift 2, a block from the car will start, when the rate increase will automatically turn a block. 2 block can be used as the upper and lower slopes of the use of the benefits of this block is on the ramp or when the down ramp, the vehicle will maintain stability in a block or two block position, not on the ramp of the imbalance in speed or load , To block transmission continuously. Drop-in slope, the use of low-speed engines for the resistance to brake, the car will not make the trip sooner.

1 (First Gear): 1 block also block progress, but only in a block transmission to work. Can not transform into other Shift. It used in serious traffic congestion and the greater the inclination of the slope can play a role. On the slopes or the slopes, they can take full advantage of the automobile engine torque.
