Abstract

The invention relates to a shift performance rack test fixture, comprising a fixture support assembly, an engine suspension supporting plate, an engine suspension, a gearbox upper suspension supporting plate, a gearbox upper suspension, a gearbox lower suspension supporting assembly, a gearbox lower suspension, a dual mass flywheel, a dual mass flywheel flange, a high-speed half shaft, an input motor, a suspension connecting plate assembly, a left half shaft, a right half shaft, a left output motor and a right output motor. In the technical solution, the fixture can match the design of the overall suspension system according to a gearbox, so that the suspension state of the gearbox on a rack is close to the overall vehicle; and the assembly of the gearbox on the rack in the overall suspension state is simulated by adopting the suspension system fixture support for assembly the whole vehicle and an auxiliary fixture for connecting the gearbox and the suspension system, so that the influence of the proper mass of the rack on vibration of the shift process is isolated.

Description

technical field [0001] The invention belongs to the field of transmission detection, in particular to a bench test tool for shifting performance. Background technique [0002] In the development process of gearbox products, while considering the reliability and durability of the gearbox shifting function, the excellent degree of gearbox shifting performance should also be considered, such as short shifting time, small shifting shock vibration, low noise, etc. . At present, the shifting function and performance of the gearbox are verified on the bench, and the gearbox installation schemes adopted are basically: the direct connection between the shifting surface of the gearbox and the input motor of the bench. Its advantages are reliable and stable installation, and it is easy to realize that the speed and torque input by the motor are concentric with the input shaft of the gearbox. However, this also makes the gearbox and the bench motor (even) and its floor solidly connect...
