Clutch pedal booster, clutch pedal, clutch assembly and automobile

Abstract

The invention discloses a clutch pedal power assisting device, a clutch pedal, a clutch assembly and an automobile. The clutch pedal power assisting device comprises a first tube body, a second tube body, a spring and a third tube body. The first tube body is provided with a first hydraulic cavity used for communicating with a clutch main cylinder; the second tube body is provided with a second hydraulic cavity, and the second tube body is arranged outside the first tube body in a sleeving mode and can move in the axial direction of the first tube body; the peripheral face of the second tube body is sleeved with the spring; and the third tube body is provided with an inner cavity, and the spring is sleeved with the third tube body in the mode that the third tube body can move axially. Assisting power provided by the clutch pedal power assisting device for the clutch pedal can be changed according to hydraulic pressure of hydraulic oil in the clutch main cylinder. The magnitude of pedalforce generated by stepping of a driver on the clutch pedal can be also changed, and the fatigue feeling of the driver due to long-term stepping on the clutch pedal is reduced.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a clutch pedal booster, a clutch pedal, a clutch assembly and an automobile. Background technique [0002] The clutch pedal of a car is an important control mechanism of a manual transmission model. The driver realizes the separation of the clutch by stepping on the clutch pedal, thereby interrupting the transmission of engine power. The size of the pedal force that the driver steps on the clutch pedal directly affects the driver's driving comfort. In order to adjust the size of the clutch pedal force, the current general way is to install a spring on the clutch pedal. [0003] refer to figure 1 , the clutch pedal includes a pedal support 1 and a pedal arm 2, and the pedal arm 2 passes through a rotating shaft 3 ( figure 1 Shown in O point in the middle) realizes rotational connection with pedal support 1. Also comprise spring 4, one end of spring 4 ( figure 1 Shown in p...

AI Technical Summary

Problems solved by technology

However, as the mileage of the vehicle increases, the amount of clutch wear increases, the separation force of the clutch increases, and the force transmitted from the clutch to the clutch pedal increases accordingly, while the power assistance provided by the spring 4 remains unchanged, causing the driver to step on the clutch pedal. If the force is increased, the driver will feel fatigue if he presses the clutch pedal for a long time, which will affect the driving comfort of the driver.
