Embodiment Construction

[0026] For ease of understanding, the spatial orientation is now specified: see figure 1 , it is stipulated that the position of the electric wheel assembly 1 is "left", and the position of the inclination encoder 8 is correspondingly "right"; the position of the vertical electric push rod 11 is "up", and the horizontal electric push rod is correspondingly 6. The position is "down"; take kingpin rotating seat 4 as "front", and correspondingly take main slider 13 as "back"; "The direction is vertical, and the "front" and "back" directions are vertical.

[0027] see figure 1 , figure 2 , the electric wheel assembly 1 is pressed on the surface of the chassis dynamometer 2 installed in the pit. The central axis of the electric wheel assembly 1 is coaxially connected with the motor shaft 1a. There is kingpin 3 on the right side of motor shaft 1a, and the middle interference fit of motor shaft 1a and kingpin 3 is connected together. The kingpin 3 is a cylindrical stepped shaft...

Abstract

The invention discloses an electric wheel experimental device and method with a steering function in the field of electric vehicle testing. The electric wheel experimental device has a steering simulating mechanism capable of researching the load state and the motion characteristic of an electric wheel on a steering condition, uses a servo motor to drive a ball screw to drive multilayer slide blocks and the roller surface of an electric wheel compaction chassis dynamometer to generate vertical force for simulating the vertical load of the electric wheel; uses a kingpin, an electric push rod, and the multilayer slide blocks to simulate the wheel positioning parameters of the electric wheel, such as a kingpin caster angle; may research the influence of the positioning parameter on the operating condition performance tests of the electric wheel, guarantees that the electric wheel is more close to an actual operation state in test simulation in order to obtain accurate and reliable test results, may complete a load applying function, a steering simulating function, a tire positioning parameter simulating function, and an operating condition running function of the electric wheel, and achieves complete functions and a simulation effect complying with actual cases.

Description

technical field [0001] The invention relates to a test device, in particular to a special multifunctional test bench for electric wheels of an electric vehicle, which belongs to the field of electric vehicle testing. Background technique [0002] Electric vehicles are driven by electric wheels, and the performance test of electric wheels is an important link in the development process of electric vehicles. At present, electric wheel and drum test benches are mostly used in the relevant test equipment for electric wheels. The test bench takes the electric wheel module as the research object, and simulates the movement of the electric wheel module on the road surface on the drum test bench and performs data collection and analysis. Therefore, it is the key to test the reliability of an electric wheel test bench whether it can accurately simulate the actual load condition and operating condition of the electric wheel. [0003] At present, there are some related designs of elec...
