Abstract

The invention belongs to the field of sealing engineering of automobile transmission devices, and particularly relates to a testing device used for estimating and testing the performance of an automotive rotary sealing ring. The technical scheme of an automotive rotary sealing ring testing device includes that the automotive rotary sealing ring testing device is used for testing the performance of the sealing ring and comprises a driving motor, a pump, a filter, an oil tank, an overflow valve, a pressure sensor A, a flowmeter, a torque sensor, a variable frequency driving motor, an oil inlet sleeve, an oil distribution sleeve, a pressure sensor B, a temperature sensor, a heat-sink cooling device and a box body used for fixing the oil inlet sleeve. The automotive rotary sealing ring testing device can be used for real simulation of a real working environment of the rotary sealing ring, a plurality of different working conditions can be provided by means of speed regulation, pressure regulation, temperature controlling and the like, and the performance of the sealing ring can be estimated by means of testing of a leakage rate and abrasion at the same time.

Description

technical field [0001] The invention belongs to the field of sealing engineering of automobile transmission devices, and in particular relates to a test device for evaluating and testing the performance of a rotary sealing ring for a vehicle. Background technique [0002] In the vehicle transmission system, the rotary sealing ring is used in the oil distribution device of the wet clutch or brake, and is the key sealing element. The performance of the sealing ring directly affects the overall performance, safety, reliability and durability of the transmission. With the development of vehicle transmission technology in the direction of high PV value and multiple working conditions, higher requirements are put forward for the performance of the rotary seal ring. However, in the prior art, there is no experimental device specially used to test the performance of the rotary seal ring. . Contents of the invention [0003] The purpose of the present invention is to provide a veh...
