Abstract

The invention discloses a vehicle suspension performance test device comprising an installing support, hydraulic cylinders, a flat plate, suspensions, suspension supports, rotating devices, road surface condition simulation devices, connecting devices, driving systems and a test system. The installing support is fixedly connected with the hydraulic cylinders which are fixedly connected with the flat plate. The suspensions are connected with the suspension supports through threads. The suspension supports are installed on the connecting devices through bearings and connected with the installing support through connecting members. The rotating devices are installed on the road surface condition simulation devices equipped with rollers. The road surface condition simulation devices fixed on the road surface can simulate different road conditions according to different excitations. The rotating devices are connected with the driving systems through the connecting devices. Simulation is performed by using a 1/2 vehicle model, and a certain load is applied with cooperation of the hydraulic cylinders. When the driving systems drive the vehicle wheels to rotate on the rollers of the road surface condition simulation devices, the movement of the suspensions is closer to the actual driving state, and the preliminary suspension performance test can be realized so as to reduce the development cost.

Description

technical field [0001] The invention relates to an auxiliary experiment device, in particular to a vehicle suspension performance test device. Background technique [0002] Suspension is one of the important components of modern automobiles. It can transmit all forces and moments acting between the wheels and the body, and can ease the impact of the road surface and attenuate vibrations. The performance of the suspension affects the handling performance of the vehicle, and its function is to ensure the smoothness and safety of driving. At present, most of the vehicle suspension performance test devices use the whole vehicle model, and use the vibration table or the electro-hydraulic servo cylinder as the excitation source to give the tire excitation input. The tire is in the non-driving state during the test, and there is a certain deviation from the actual road conditions, which reduces the experimental results. reliability. Therefore, it is of great significance to desig...
