Abstract

The invention discloses a hub motor experiment bench device and an experiment system thereof. The hub motor experiment bench device comprises a bench part, a hub electric wheel system, a vibration exciter and a transmitting system. The bench part comprises a main base and a vertical column, and the hub electric wheel system is fixed to the vertical column. The vibration exciter and the transmitting system are fixed to the main base and located below the hub electric wheel system. During experimenting, a motor controller controls a hub motor to obtain the rotating speed needed by experimenting,a vibration exciter controller transmits a vibrating signal to the vibration exciter, the vibration exciter works to simulate the hub motor to receive pavement excitation to vibrate to drive a supporting column in the center of the vertical column to transmit the vibrating signal to idler wheels and tires in sequence, all sensors measure working condition parameters of the hub motor, and measureddata are input into a computer to be processed. Dynamic data of the hub motor can be obtained, a pavement excitation signal is further exerted through the vibration exciter and the transmitting system to enable the motor to vibrate, and then smoothness of an electric car driven by the hub motor is researched.

Description

technical field [0001] The invention relates to an in-wheel motor test bench, which belongs to the technical field of electric vehicle devices, and in particular relates to an in-wheel motor test bench device and an experimental system thereof. The basic characteristics can also be tested by simulating the application of road excitation to test the ride comfort of a quarter model of the in-wheel motor-driven car, which provides a basis for the design of the entire vehicle. Background technique [0002] With the intensification of energy crisis and environmental pollution, the world is vigorously developing new energy vehicles and hybrid technology. The in-wheel motor-driven electric vehicle has the advantages of small size, high specific power, high transmission efficiency, and simplified vehicle structure because it omits the transmission, universal transmission, differential and half shafts of the traditional vehicle power transmission system. advantage. At the same time...
