Separation rocker arm durability reliability test experiment bench and durability reliability test method

Abstract

The invention discloses a separation rocker arm durability reliability test experiment bench and durability reliability test method. The separation rocker arm durability reliability test experiment bench includes an actuator, a force sensor, a clutch cable and a transmission assembly; one end of the actuator is fixed; the other end of the actuator is connected with one end of the force sensor; theother end of the force sensor is connected with one end of the clutch cable; the other end of the clutch cable is connected with one end of a separation rocker arm; and the separation rocker arm is hinged onto the outer wall of the transmission assembly. During the extension and contraction movement of the actuator, an acting force of the actuator, which is applied onto the separation rocker arm,is monitored through the force sensor; when an abnormality occurs, testing is suspended, and a box is disassembled, so that parts can be checked; when the actuator extends and contracts, the separation rocker arm operates, the actuator pulls and releases the separation rocker arm in a reciprocating manner through the clutch cable according to a separation stroke; and after the cumulative number of the times of the action of the separation rocker arm achieves the design number of the times of the action of the service life of the separation rocker arm, the testing is suspended, and the box isdisassembled, and whether conditions such as abnormal deformation and fracture occur on the separation rocker arm is checked.

Description

technical field [0001] The invention relates to the field of detection devices for a separation rocker arm, in particular to an experimental bench for testing the durability and reliability of a separation rocker arm. [0002] The invention relates to the field of separation rocker arm detection methods, in particular to a durability reliability test method for a separation rocker arm durability reliability test bench. Background technique [0003] At present, the separation rocker arm is an important part in the automobile transmission assembly. When it is abnormally deformed or broken, the separation function of the transmission will fail, the car cannot run normally, and even cause serious consequences of safety accidents. [0004] The durability and reliability verification of the separation rocker arm is generally carried out through road tests. Due to the limitation of the driving regulations of the road test, the design working life of the separation rocker arm cannot...

AI Technical Summary

Problems solved by technology

[0003] At present, the separation rocker arm is an important part of the automobile transmission assembly. When it is abnormally deformed or broken, the separation function of the transmission will fail, the car cannot run normally, and even cause serious consequences of safety accidents.

[0004] The durability and reliability verification of the separation rocker arm is generally carried out through road tests. Due to the limitation of the driving regulations of the road test, the design working life of the separation rocker arm cannot be achieved, and the durability and reliability of the separation rocker arm cannot be fully verified.
