Embodiment Construction

[0015] Below just in conjunction with accompanying drawing, the present invention will be further described;

[0016] For manual clutch automatic shifting system, in conjunction with the present invention shows figure 1 , 2 ; In the normal driving state (non-shifting state), the solenoid valve is in the normally open state, and the cam and shift lever of the automatic shifting device are as follows: figure 2 location shown. Under the effect of clutch spring, clutch is in combined state, and by clutch backguy, clutch wire pulley, slide shaft, bearing, throttle wire pulley are pulled upwards, and bearing is pressed against on the cam base garden. When the controller determines to shift gears by analyzing the signals of each sensor, the controller first controls the rotation of the reduction motor of the automatic gear shifting device, thereby driving the rotation of the cam and the lever shaft. The rotation of the cam drives the bearing to drive the sliding shaft to move dow...

Abstract

The invention provides a motor vehicle automatic shift system device. The motor vehicle automatic shift system device is characterized in that accelerator motion control, clutch motion control and shift motion control in the motor vehicle shifting process are integrated into one automatic shift device, and all operation of automatic shifting can be completed only by manipulating a motor and a magnetic valve. Not only complexity of an automatic shift manipulating mechanism and difficulty of control can be simplified, but also reliability can be improved, and product cost can be lowered.

Description

(1) Technical field [0001] The invention relates to the field of power transmission of motor vehicles, in particular to the automatic shifting technology of motor vehicles. The current automatic gear shifting of motor vehicles can be divided into hydraulic automatic transmissions (abbreviated AT transmissions) and electronically controlled automatic transmissions (abbreviated AMT transmissions). The invention belongs to an automatic shifting device of an electronically controlled automatic transmission. (2) Background technology [0002] The control of the electronically controlled automatic transmission of a motor vehicle requires precise control of the accelerator, clutch, and shifting actions. At present, electronically controlled automatic transmissions usually require the precise cooperation of 3 to 4 motor drives to realize automatic gear shifting. Its control mechanism is complicated, the cost is high, and the control difficulty is great. (3) Contents of the inven...
