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

[0036] 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.

[0037] Each subsystem is described below:

[0038] (1) Driver loading system

[0039] The driving and loading system is composed of AC inverter, driving motor, static torsion motor, loading motor, two-speed gearbox, coupling, drive shaft, motor mounting base, gearbox mounting base, bearing housing and corresponding control electrical circuits. The electric control schematic diagram of the driving and loading system is shown in figure 1 .

[0040] The loading motor is used to simulate the load inertia, and the driving motor is used to simul...

Abstract

The invention discloses a multifunctional clutch test stand. According to the multifunctional clutch test stand, an output shaft of a driving motor is connected with an I-shift input shaft of a two-shift gearbox through a first torque sensor, a static torque motor is connected with a II-shift input shaft of the two-shift gearbox through a third torque sensor, an output shaft of the two-shift gearbox is connected with an input shaft of a tested clutch through a second torque sensor, and an output shaft of the tested clutch is connected with a loading motor through a transition transmission shaft. When the two-shift gearbox is at the I shift, the driving motor is switched onto the tested clutch, when the two-shift gearbox is at the II shift, and the static torque motor is connected with the tested clutch. The transition transmission shaft is equipped with a shaft locking device, when the tested clutch and the static torque motor are switched on, the shaft locking device realizes locking, and static torque tests on the tested clutch are carried out. The multifunctional clutch test stand has advantages of simple operation, high automation degree, excellent reliability and maintainability and strong security.

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...
