Problems solved by technology

[0002] Existing clutch test benches have single functions, and most of them can only do clutch durability tests and general performance tests, and cannot fully simulate the actual working conditions of clutches, cannot do static torsion tests of clutches, cannot simulate road spectrum, and cannot measure clutch friction Chip temperature distribution
The inertia simulation accuracy of the existing clutch test bench is low, and most of them use the flywheel to simulate the moment of inertia, which cannot realize stepless inertia adjustment.
The drive motors of the existing clutch test benches have a large inertia, which cannot truly reproduce the characteristics of the engine. The impact received by different simulated clutches in actual working conditions

Embodiment Construction

[0037] figure 1 It is a multifunctional clutch test bench (hereinafter referred to as the test bench). The test bench consists of a drive loading system, a clutch piston pressure oil supply adjustment system, a clutch lubricating oil temperature control system, a clutch ambient temperature control system, a real-time control system, a sensor data acquisition system, an auxiliary monitoring system and an upper computer operating system.

[0038] Each subsystem is described below:

[0039] (1) Driver loading system

[0040] The driving and loading system is composed of AC inverter, driving motor, static torsion motor, loading motor, two-speed gearbox, coupling, transmission shaft, motor mounting base, gearbox mounting base, bearing housing and corresponding control electrical circuits. The electric control schematic diagram of the drive and loading system is shown in figure 1 .

[0041] The loading motor is used to simulate the load inertia, and the driving motor is used to ...

Abstract

The invention discloses a multifunctional clutch test bench. The output shaft of the drive motor is connected with the I gear input shaft of the two-speed gearbox through the first torque sensor, and the static torsion motor is input with the II gear of the two-speed gearbox through the third torque sensor. shaft connection, the output shaft of the two-speed gearbox is connected to the input shaft of the tested clutch through the second torque sensor, and the output shaft of the tested clutch is connected to the loading motor through a transition transmission shaft; when the two-speed gearbox is placed in I gear, the drive motor Connect with the tested clutch, and when the two-speed gearbox is placed in gear II, the static torsion motor is connected to the tested clutch; a shaft locking device is installed on the transition transmission shaft, and when the clutch is connected to the static torsion motor, the shaft is locked The device is locked, and the static torsion test of the tested clutch is carried out. The invention has simple operation, high degree of automation, good reliability and maintainability, and strong safety.

Description

technical field [0001] The invention relates to a multifunctional clutch test bench. Background technique [0002] Existing clutch test benches have single functions, and most of them can only do clutch durability tests and general performance tests, and cannot fully simulate the actual working conditions of clutches, cannot do static torsion tests of clutches, cannot simulate road spectrum, and cannot measure clutch friction slice temperature distribution. The inertia simulation accuracy of the existing clutch test bench is low, and most of them use the flywheel to simulate the moment of inertia, which cannot realize stepless inertia adjustment. The drive motors of the existing clutch test benches have a large inertia, which cannot truly reproduce the characteristics of the engine, and differently simulate the impact of the clutch in actual working conditions. Due to the complex actual environmental conditions of the clutch, performance tests and reliability tests in high...
