Auxiliary engagement device for clutch

Abstract

The invention provides an auxiliary engagement device for a clutch and belongs to the technical field of automobiles. The problem that the clutch cannot be engaged quickly by trampling an accelerator pedal in the conventional automobile is solved. The auxiliary engagement device for the clutch is arranged in a clutch hydraulic control mechanism; the clutch hydraulic control mechanism comprises a liquid storage cylinder, a main cylinder which is communicated with the liquid storage cylinder, and a working cylinder connected with the clutch; the auxiliary engagement device for the clutch comprises a solenoid valve arranged between the main cylinder and the working cylinder, and a control circuit which can control the solenoid valve to be opened and closed when the accelerator pedal is trampled; and a one-way oil return pipeline in which oil can only flow from the working cylinder to the liquid storage cylinder is arranged between the working cylinder and the liquid storage cylinder. The auxiliary engagement device for the clutch is easy to control, the cultch can be engaged quickly by tramping the accelerator pedal, and the auxiliary engagement device is convenient to use.

Description

technical field [0001] The invention belongs to the technical field of automobiles and relates to a clutch auxiliary engaging device. Background technique [0002] With the advancement of society and the rapid development of the automobile industry, people's living standards continue to improve, and automobiles have become one of the important means of transportation for people to travel. During the driving process of the car, the driver can step on or release the clutch pedal as needed to temporarily separate and gradually engage the engine and the transmission, so as to cut off or transmit the power input from the engine to the transmission. [0003] At present, friction clutches are mostly used with manual transmissions, and torque is transmitted between the driving disc and the driven disc of the clutch relying on the friction effect of spring compression.

AI Technical Summary

Problems solved by technology

[0003] At present, friction clutches are mostly used with manual transmissions, and torque is transmitted between the driving disc and the driven disc of the clutch relying on the friction effect of spring compression. This kind of mechanical manipulation requires a high level of driver's operation; Some cars in China use small-displacement engines, which are easy to stall when the vehicle starts idling or accelerates due to the driver stepping on the accelerator without fully releasing the clutch pedal in time, and the clutch itself is in a semi-linked state at high speeds. Severe wear and tear; the clutches matched by the current automatic transmission are all controlled by the ECU but the cost is relatively high; at the same time, some manual transmissions also use hydraulic clutches, and the hydraulic clutch transmission adopts hydraulic transmission. The working principle of the hydraulic clutch: When the clutch pedal is pressed , the master cylinder piston moves to the left through the push rod, the oil in the master cylinder and pipeline is pressurized, and the pressure rises. The bearing separates the clutch; the hydraulic clutch adds an electronic control unit ECU and a hydraulic executive system, and the pedal-operated clutch cylinder piston is changed to an electric oil pump controlled by a switch device to control the clutch cylinder piston. The transmission control unit and the engine control unit are integrated together. According to the sensor feedback information such as accelerator pedal, transmission gear, transmission input, output shaft speed, engine speed, throttle opening, etc., calculate the best clutch engagement time and speed
