Torsion durability fixed torque testing machine for automobile dry friction type clutch driven plate assembly

Abstract

The invention discloses a torsion durability fixed torque testing machine for an automobile dry friction type clutch driven plate assembly, which mainly comprises a base, a driving mechanism, a manualdriving loading mechanism, a torsion mechanism, a compensation mechanism and an aligning mechanism, wherein the driving mechanism, the manual driving loading mechanism, the torsion mechanism and thecompensation mechanism are respectively fixed on the base, and the aligning mechanism is fixed on the torsion mechanism; the base is provided with a frame on which a variable frequency motor is fixed;a small belt wheel is arranged on the output shaft of the variable frequency motor and transmitts power to the large belt wheel of the driving mechanism through the V-ribbed belt; a bedplate is fixedon the frame through a screw, and an outer frame is fixed on the bedplate. According to the invention, the automatic compensation of the test torque is realized; the testing machine can monitor in real time, judge when a product is invalid and realize automatic shutdown in a durability test; the measurement error caused by the clearance between the spline shaft and the spline hole of the tested workpiece is eliminated in the experimental process; the testing machine is simple and novel in structure and convenient in operation.

Description

technical field [0001] The invention relates to the field of auto parts detection, in particular to a dry friction clutch driven disk assembly torsion durability constant torque testing machine for automobiles. Background technique [0002] In the existing torsional durability testing equipment for dry friction clutch driven disc assemblies for automobiles, the test torque can only be achieved by adjusting the torsion angle, and then the entire durability test is performed by locking the torsion angle. In this way, with the decline of the torsional characteristics of the tested clutch driven disc assembly during the experiment, because the testing machine does not have the compensation function of the test torque, the actual test torque in the middle and late stages of the endurance test did not meet the test conditions and could not Effectively simulate the harsh working conditions of the car starting on a hill, so that the effective life of the clutch driven disc assembly ...
