Abstract

The invention relates to a new energy electric vehicle motor and rear axle matching performance detecting device, which comprises a detection system and a rear axle fixture, wherein the rear axle fixture is arranged on a workbench; the rear axle fixture is composed of an axle package fixture and two axle tube fixtures, and the two axle tube fixtures are respectively located at the left side and the right side of the rear axle fixture; the axle package fixture structurally comprises a positioning base, the top surface of the positioning base is provided with a sliding slot along the length direction, a rotating shaft is fixed in the sliding slot through bearing pedestals at two ends, the circumferential surface of the front end of the rotating shaft is provided with a positive thread, the circumferential surface of the rear end of the rotating shaft is provided with a negative thread, threaded holes in a front sliding block and a rear sliding block are respectively meshed with the threads at the front and rear ends of the rotating shaft, and one end of the rotating shaft is connected with a handle; and the opposite surfaces of the front sliding block and the rear sliding block are provided with positioning slots respectively, each positioning slot is internally provided with a clamping block, and the clamping surface of each clamping block is an arc-shaped surface. The device can quickly detect the noise in operation of a motor and a rear axle, thereby avoiding products with loud noise from being put into use.

Description

technical field [0001] The invention belongs to the technical field of electric vehicle rear axle detection, and in particular relates to a detection device for matching performance between a new energy electric vehicle motor and a rear axle. Background technique [0002] New energy electric vehicle motor and rear axle performance matching detection is an important indicator basis for vehicle R&D, trial production and testing, and vehicle announcement declaration. Accurate detection of vehicle component performance can shorten the test and debugging cycle, reduce test costs, and improve control accuracy etc. are of great significance. [0003] The detection methods for the performance matching between the motor and the rear axle of new energy electric vehicles include the component outline size detection system or the detection during the debugging process after the whole vehicle is off the assembly line. Once a problem occurs, it is time-consuming and labor-intensive to re...
