Clutch stroke monitoring system

Abstract

The clutch stroke monitoring system includes a clutch booster (1), on which a push plate (9) and a linked marking ruler (3) are mounted, and the left end of the linked marking ruler (3) is connected to the push plate (9), A blind hole is opened at the right end of it and installed on the right end of the housing of the clutch booster (1). The magnetic cylinder (10) is installed in the blind hole, and a sensor (2) is installed on the outer wall of one end of the blind hole. The sensor ( 2) An external wiring harness (4), the wiring harness (4) is connected to the ECU (5), and the ECU (5) is provided with an input wiring harness (8) and an output wiring harness (6). Compared with the prior art, the present invention has the beneficial effects that: the technical scheme of the present invention with the linkage marking ruler can realize the monitoring of the stroke of the clutch friction disc and timely prompt the replacement of the clutch friction disc, and can also realize the failure of the mechanical structure of the clutch and the sensor Automatically diagnose and record the clutch times and status of the clutch and provide it to the driving recorder.

Description

technical field [0001] The present invention relates to a clutch, in particular to a clutch stroke monitoring system. Background technique [0002] At present, in the field of heavy and medium-sized vehicles and commercial vehicles in China, the control part of the clutch generally adopts the control method of hydraulic control and air assist (commonly known as "liquid top gas"), that is, when the driver steps on the clutch pedal, the pedal is mechanically connected The mechanism opens the hydraulic valve of the clutch main pump to provide a certain amount of hydraulic pressure to the clutch slave pump, and the hydraulic pressure further opens the air pressure control valve of the clutch slave pump, and the push rod of the clutch booster pushes the clutch pressure plate separation mechanism under the action of gas pressure , and finally realize the disengagement and engagement of the clutch. However, the above-mentioned clutch operating system is not equipped with a monitor...

AI Technical Summary

Problems solved by technology

However, the above-mentioned clutch operating system is not equipped with a monitoring system for the clutch stroke, and the resulting technical defects are: first, the customer can only rely on frequent visits to the chassis of the vehicle to check the extension length of the marking ruler to observe and judge Whether the friction plate of the clutch is excessively worn and needs to be replaced immediately, which undoubtedly increases the labor intensity and is extremely inconvenient; secondly, the customer cannot effectively judge the mechanical failure of the sensor itself or the clutch, for example, when the clutch is deeply depressed but the booster is not working; finally , the customer has never been able to understand the number of times and status of the clutch during the vehicle's driving

However, this invention does not install an ECU at the output end of the displacement sensor, so it cannot effectively judge the mechanical failure of the sensor itself or the clutch, and it is also impossible to understand the number of clutch clutches and the state of the clutch during the vehicle's driving.
