Efficiency testing device and method for automobile clutch separating system

Abstract

The invention provides an efficiency testing device and an efficiency testing method for an auto clutch separating system. The efficiency testing device comprises a first connecting plate (10), a supporting pipe (11) and a second connecting plate (13) which are sequentially connected; a first spring seat (15), a spring (16) and a second spring seat (17) are arranged inside the supporting pipe (11); and the first spring seat (15) and the spring (16) are sequentially connected with the second spring seat (17). The force at a pedal and the displacement of the pedal can be obtained by connecting the efficiency testing device with a clutch slave cylinder, testing the stress and the displacement applied at a push rod of the slave cylinder and further connecting a pedal dynamometer to the clutch pedal; through the comparison between the forces and the displacements at the two places, the load efficiency and the stroke efficiency from the clutch pedal to the clutch slave cylinder can be obtained, further the reason for heavy clutch pedal can be diagnosed, the clutch pedal is checked and adjusted, and the auto NVH (noise vibration and harshness) performance and the control comfort degree of a driver can be improved greatly.

Description

technical field [0001] The invention relates to a test technology of a clutch separation system, in particular to an efficiency test device and method of an automobile clutch separation system. Background technique [0002] Clutch release system, as the actuator for operating the clutch in the car, includes pedals, ropes or hydraulic mechanisms, clutch release arms, clutch release shafts and release bearings, etc., which have an important impact on the power transmission and NVH performance of the vehicle, especially It is the separation force of the clutch pedal, which seriously affects the driver's control comfort. [0003] Clutch release system, as the actuator for operating the clutch in the car, includes pedals, ropes or hydraulic mechanisms, clutch release arms, clutch release shafts and release bearings, etc., which have an important impact on the power transmission and NVH performance of the vehicle, especially It is the separation force of the clutch pedal, which s...

AI Technical Summary

Problems solved by technology

However, the clutch separation system actually produced at present often has a large gap between the pedal force and the pedal stroke of the original design; moreover, there are certain errors in the installation process of the car; especially, the current clutch separation system In the design check, only the total load efficiency and stroke efficiency experience value, there is no simple measurement method to obtain the load efficiency and stroke efficiency from the clutch pedal to the clutch cylinder

These are very detrimental to the improvement of the load efficiency and stroke efficiency of the clutch separation system, seriously affecting the power transmission, NVH performance and driver's control comfort of the car
