Abstract

The invention discloses a multifunctional test bed for an electric wheel. The test bed comprises a power measuring motor, an electric push rod, a loading motor, an electric wheel equipped with a hud motor, a rotary drum, a rotating speed torque sensor, a pressure sensor, a ball screw mechanism, a parent controler (computer), an A / D & D / A card, and a USB / CAN adapter, whrein, the computer controls the rotating speed of the power measuring motor through the D / A card according to experimental operating conditions, the computer dynamically controls vertical load which is applied by the loading motor to the electric wheel through the D / A card according to the experimental operating conditions, the computer controls torque of the electric wheel r which is equipped with the hud motor through the USB / CAN adapter according to the experimental operating conditions, and the pressure sensor and the rotating speed torque sensor send load, rotating speed and torque signals of the electric wheel to the computer through the A / D card and a serial port respectively. The multifunctional test bed for the electric wheel can automatically assess durability of the electric wheel without monitoring in thelaboratory and without arranging special experimenter to carry out road test, and has the advantages of saving manpower and material resources, providing rapid and accurate assessment and the like.

Description

technical field [0001] The invention belongs to the bench test technology of a power transmission system, and in particular relates to a novel multifunctional test bench for a hub motor drive module (electric wheel for short) of a wheel-side electric drive vehicle. Background technique [0002] Wheel-side electric drive vehicles generally do not have internal combustion engines, only hub motors and batteries (such as batteries, fuel cells, etc.) Advanced automotive energy-saving and environmental protection technologies have received extensive attention and research around the world. As a new type of power transmission technology, the wheel-side electric vehicle power transmission system with the integrated electric / power generation hub motor as an important component still lacks a corresponding multifunctional test bench for the durability of the drive system and the electric wheel system. Based on the needs of the development of pure electric wheel drive system, a multifu...
