Vehicle electric wheel multifunctional testing table

Abstract

The invention provides a vehicle electric wheel multifunctional testing table and belongs to the technical field of electric vehicles. The testing table comprises a power supply module, a testing table frame body, a vertical loading system, a steering system and a rolling drum system. The power supply module is respectively connected with the vertical loading system, the steering system and the rolling drum system and provides power for the systems. The testing table frame body is constructed as a testing table body frame which provides supporting for the vertical loading system and the steering system. The vertical loading system and the steering system are both placed on the testing table frame body and load vertical force and steering force on an electric wheel respectively. The rolling drum system is separated from the testing table frame body and is used for simulating road conditions and vehicle rotational inertia. According to the vehicle electric wheel multifunctional testing table, testing and evaluation can be carried out on relationship of tyre force and slip ratio, driving anti-slip performance, slip ratio control performance under hydraulic braking, motor durability, motor dynamic performance and the like of an electric wheel system under large side force, and meanwhile the vehicle electric wheel multifunctional testing table is suitable for multifunctional testing of a traditional tyre beyond motor performance testing.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, and relates to a wheel test equipment, in particular to an electric wheel test equipment. Background technique [0002] Wheelside electric drive vehicles have incomparable advantages in energy saving, environmental protection and performance compared to traditional vehicles. They are the product of social and economic interests and energy and environmental protection requirements. As a new type of power transmission system, the wheel-side electric drive vehicle power transmission system with in-wheel motors as an important component still lacks a corresponding multi-functional test bench to test the tire force and force of the electric wheel system under large lateral force Slip rate relationship, drive anti-slip, slip rate control under hydraulic braking, motor durability, motor dynamic characteristics, etc. are tested and evaluated. Therefore, it is a test equipment that can test and...
