Chassis testing device with four wheels driven and turned independently

The invention relates to a chassis testing device with four wheels driven and turned independently, belongs to the field of vehicle engineering, aims to overcome the deficiency of conventional chassis testing device, and discloses a chassis testing device with four wheels driven and turned independently that can convert rectilinear motion to circular motion. The technical scheme of the invention is that a rotary plate mechanism of which the center of gyration is concentric with the steering shaft of the tested chassis driving wheel is adopted; the chassis is fixed onto the rotary plate mechanism through support; and the chassis performance parameter test with four wheels driven and turned independently can be performed. The chassis testing device with four wheels driven and turned independently disclosed by the invention has the following advantages: firstly, the performance test can be conducted in situ without rectilinear motion; secondly, the sensor can be arranged easily, and the speed and the load can be
