Problems solved by technology

Among them, the most significant advantage of the mechanical closed test bench is energy saving, which can reduce the operating cost, but compared with the open test bench, it increases the transmission device and the servo loading device, the composition is relatively complicated, and the price is relatively expensive; The mechanical structure of the electric energy closed test bench is simple and compact, the power loss is small, the efficiency is high, and the heat generation is reduced. However, the power recovery method is to convert the mechanical energy output by the drive axle into electrical energy, and then recover it through the power grid. The structure and technology of the power system are complicated. high cost

Abstract

The invention discloses a closed drive axle testing device capable of automatically simulating vehicle steering. The input shaft end of the left transmission box is connected with the left input shaft of the test drive axle; the right output shaft of the tested drive axle is connected with the first input shaft end of the right transmission box, and the steering motor The output shaft is connected to the second input shaft end of the right transmission box, and the output shaft end of the right transmission box is connected to the right input shaft of the accompanying test drive axle; the output end of the accompanying test drive axle is connected to the loading hydraulic pump; the loading hydraulic pressure A hydraulic pipeline is arranged between the output oil port of the pump and the input oil port of the hydraulic motor. The hydraulic system arranged in the invention can return the mechanical energy of the output end of the tested drive axle to the input end of the tested drive axle, so that the output energy of the drive axle becomes the test power; the energy recovery method is simple.

Description

[0001] 【Technical field】 [0002] The invention belongs to the technical field of vehicle structural performance testing, in particular to a device for testing the performance of a vehicle drive axle. [0003] 【Background technique】 [0004] At present, there are generally two types of benches for testing the dynamic performance of drive axles. One is an open drive axle test bench in which the power flow of the test bench is not closed. The open test bench has a simple structure and is easy to install, but the output power of the drive axle can no longer be used for feedback, the test bench consumes a lot of energy, and the test cost is high. Usually, this kind of test bench is suitable for drive axle tests with small test power or short test periods. . The other is a closed test bench with a power flow cycle of the test bench. This kind of test bench can recover the energy consumed by the test, and the test energy loss is small. It is suitable for the drive axle test with hig...
