Abstract

The invention discloses an automobile kinetics dynamical property test system based on integrated rollers. The system is composed of a measurement and control system and a plurality of integrated rollers; the number and arrangement of the integrated rollers are determined by automobile type and test requirement, each integrated roller consists of a central shaft, a brake fixing bracket, a brake disc, a floating-caliper brake, a roller, a six-component sensor, a rotation speed sensor, a code disc, an external rotor electric machine and a bracket. The invention has the beneficial effects that the six-component sensor is used for measuring tangential force, axial force, vertical force, turning moment, moment resulting from sideway and yawing moment to realize measurement on tyre longitudinal force, yawing force, vertical load, turning moment, moment resulting from sideway and aligning torque, and that the test system has the advantages of simple and compact structure, reduced installation space and the like. The attached drawings are diagrammatic drawings for structure of the integrated rollers and connection between the integrated rollers and the measurement and control system.

Description

technical field [0001] The invention relates to an automobile testing device, in particular to a device for testing the dynamic characteristics of automobile dynamics. Background technique [0002] Most of the existing vehicle dynamics dynamic characteristic test systems are based on the vehicle chassis dynamometer with auxiliary equipment for measurement. / Hydraulic type and inertial type, etc. The basic principle is to use the drum to simulate the road surface, put the driving wheel of the car on the drum, drive the drum to rotate, control the resistance to the drum, and simulate different driving resistance. The speed sensor and the torque sensor measure the resistance and the speed of the drum at a certain moment, and calculate the torque and speed of the wheel. The above-mentioned chassis dynamometer can only measure the tangential force and rotational moment of the drum, but cannot measure the vertical load, axial force, roll moment and yaw moment of the drum, and can...
