Description

A drive motor dynamometer test bench

technical field

The utility model relates to a dynamometer test bench, in particular to a driving motor dynamometer test bench.

Background technique

As an environmentally friendly and efficient vehicle, electric vehicles have attracted more and more attention. As one of the core components of electric vehicles, the drive motor determines the performance of the vehicle, so the production and testing of the drive motor has become particularly important. At present, the dynamometer test bench for electric vehicle drive motors has the following problems when performing performance testing such as motor power: the drive motor and the dynamometer shaft are connected by a coupling, and the drive motor needs to be fixed on the base of the test bench. When installing, two bolts of sufficient length are often used to span the left and right sides of the motor. The bottom ends of the two long bolts are flexibly connected to the base of the test bench. A pressure plate is placed horizontally on the upper part of the motor. The motor is fixed on the base of the dynamometer test bench. When testing each driving motor, it is necessary to disassemble and install the pressure plate, and sometimes the fixed position is not accurate, resulting in wrong detection results. The driving motor needs to be fixed again. The operation process is complicated and the installation efficiency is high. Low, the installation position is not accurate, the detection efficiency is greatly reduced, and its performance needs to be further improved.
