Abstract

The invention provides a multifunctional performance test bed of a four-wheel independent drive electric vehicle with hub motors. The multifunctional performance test bed comprises a control system, a data acquisition system, an electrical system, an energy supply system and four sets of single-wheel racks. Each set of single-wheel rack comprises a testing system, a tested system and a rack supporting structure. Each testing system comprises a power testing motor, a speed increaser, a torque sensor and a flexible coupling, and each speed increaser is integrated with a test gear-shifting execution mechanism. Each tested system comprises a speed reducer and a tested hub motor, each speed reducer is connected with the corresponding flexible coupling, and each rack supporting structure comprises a base which is provided with a testing system supporting part and a tested system supporting part; the four testing systems form a testing system network through a CAN bus, and the four tested systems form a tested system network through a CAN bus. The multifunctional performance test bed can achieve joint debugging basic performance testing of a power system of the four-wheel independent drive electric vehicle with the hub motors, and also can carry out independent performance testing experiments on every hub motor.

Description

technical field [0001] The invention relates to the field of testing and testing of electric vehicles, in particular to a four-wheel independently driven multifunctional performance test bench for hub motors. Background technique [0002] In-wheel motor four-wheel independent drive electric vehicles will definitely be one of the inevitable directions for the development of electric vehicles in the future. It has the advantages of simple layout, low chassis, diverse driving methods, large driving torque, and strong controllability. The hub motor is a power device that integrates driving, braking and deceleration devices, and is mainly used for four-wheel independent drive vehicles. In-wheel motor four-wheel independent drive electric vehicles can realize a variety of motion forms, such as turning in place and wedge-shaped motion, making its control strategy more complex and control accuracy higher, but there are certain differences from traditional internal combustion engine ...
