Description

Technical Field

[0001] This utility model relates to the technical field of transverse electric vehicle gearbox bench installation, and in particular to a test connection fixture for a transverse electric vehicle gearbox bench. Background Technology

[0002] A transverse electric vehicle gearbox test bench is a device used to test transversely mounted gearboxes. This bench typically includes a series of components such as a first synchronous pulley, drive shaft, second synchronous pulley, first power connection mechanism, first splined shaft, second splined shaft, second power connection mechanism, first bearing, flywheel, second bearing, coupling, variable frequency motor, bearing housing, motor support frame, and gearbox bracket. These components work together to simulate the vehicle speed and inertia during driving, thereby conducting dynamic shifting and break-in tests on the transversely mounted gearbox. In existing transverse electric vehicle gearbox connection fixtures, when installed with the motor output end on the test bench, the gearbox connection shaft is prone to wobbling, leading to unstable power transmission. Repeated clamping is cumbersome, time-consuming, and may cause varying degrees of damage to the gearbox input shaft. Therefore, we propose a transverse electric vehicle gearbox test connection fixture. Utility Model Content
