Problems solved by technology
Due to its smaller impact on the environment than traditional cars, its prospects are widely optimistic, but the current technology is not yet mature
However, the current dynamic loading test platform for electric wheels mainly focuses on the performance test of the hub motor in the electric wheel, which cannot fully reflect the performance of the 1 / 4 body electric wheel system, resulting in insufficient measurement accuracy of the electric wheel. The research and development efficiency of electric vehicles, so design a bench test platform for electric wheel suspension system, which has good reference value and application value for the development of pure electric vehicles

The invention provides an electric wheel suspension system testing stand of a hub driven electromobile. The testing stand comprises a fixed pedestal and a total frame, the fixed pedestal is arranged in the lower end of the total frame, the total frame is provided with a suspension device, an electric wheel and a roller device, the suspension device is composed of an upper swing arm, a steering knuckle and a lower swing arm, one end of the upper swing arm is connected via hinging blocks on the total frame, the other end of the upper swing arm is hinged to the steering knuckle, the lower end of the steering knuckle is connected with one end of the lower swing arm via a bulb, the other end of the lower swing arm is hinged to fixing blocks on the total frame, the electric wheel is arranged in the right end of the steering knuckle, and the roller device is arranged under the electric wheel via a roller support. The whole electric wheel structure does not include a mechanical driving mechanism, the structure is compact, and the transmission efficiency is high; in motion test of the electromobile in practical condition, a vertical load simulation mechanism can simulate load, torque and rotating speed change of electric wheels in practical condition; and the testing stand can carry out electronic differential speed test and braking test on the electric wheels.
Description
technical field [0001] The invention relates to the field of electric vehicles, in particular to a test bench for an electric wheel suspension system of a hub-driven electric vehicle. Background technique [0002] Energy shortage and environmental pollution in the 21st century are two major problems that need to be solved. In solving these two problems, electric vehicles have irreplaceable advantages. An electric vehicle (BEV) refers to a vehicle that is powered by a vehicle-mounted power supply, drives the wheels with a motor, and meets the requirements of road traffic and safety regulations. Due to its smaller impact on the environment than traditional cars, its prospects are widely optimistic, but the current technology is still immature. However, the current dynamic loading test platform for electric wheels mainly focuses on the performance test of the hub motor in the electric wheel, which cannot fully reflect the performance of the 1 / 4 body electric wheel system, res...
