Problems solved by technology
[0004] However, there is a certain amount of air in the transmission oil circuit. In theory, the hydraulic oil cannot be compressed, but the air can be compressed. In the process of shifting, there will inevitably be a risk of shifting impact and insufficient shifting. There are the following disadvantages:
[0005] 1. The double-piston mechanism is large in size, difficult to process and high in cost
[0006] 2. The piston drain oil circuit and the oil inlet oil circuit are one oil circuit, so the oil drain effect is poor
[0007] 3. There is no pressure relief buffer device in the existing structure, and there will be shifting shock during the shifting process

The invention discloses an automobile clutch shift fork control device, relates to the field of automobile clutches, and is invented for reducing the volume of the automobile clutch shift fork control device, and reducing the processing difficulty and manufacturing cost of the automobile clutch shift fork control device. The automobile clutch shift fork control device includes a cylinder liner, a piston is fitted inside the cylinder liner, a piston rod is provided at one end of the piston, and the piston rod is used to connect with the automobile clutch shift fork, and the two ends of the cylinder liner A first oil inlet and a second oil inlet are opened respectively, the first oil inlet is connected with a first oil inlet circuit, the first oil inlet circuit is connected to the first electromagnetic valve, and the second oil inlet The oil port is connected with a second oil inlet passage, and the second oil inlet passage communicates with the second electromagnetic valve. The automobile clutch shift fork control device of the invention is suitable for automobiles.
Description
technical field [0001] The invention relates to the technical field of automobile clutches, in particular to an automobile clutch shift fork control device. Background technique [0002] With the development of the automobile industry, people pay more and more attention to the performance of automobiles, and there are many factors that affect the performance of automobiles, such as automobile transmissions. Generally, the shifting process of automobile transmissions is through the cooperation of automobile clutch shift forks in the transmission. gear to achieve. [0003] The existing car clutch fork is controlled by double pistons, that is, a control piston is installed on both sides of the car clutch fork. When the corresponding solenoid valve receives the signal, the corresponding oil circuit is opened to push the piston to move, and the piston pushes the car. The clutch fork moves to complete the shift, and through the movement of two sets of solenoid valves and two sets...
