Abstract

The invention relates to the technical field of vehicle experiments, in particular to a road simulation testbed for a wheel.The road simulation testbed comprises a vertical excitation system coaxially connected with a wheel to be tested and a revolving drum system arranged below the wheel to be tested; the revolving drum system comprises a revolving drum and a first drive device for driving the revolving drum to rotate, and the outer cylindrical face of the revolving drum is in rolling contact connection with the outer circumferential face of the wheel to be tested so that the driving state on a road of a vehicle can be stimulated; the vertical excitation system comprises a hanger bracket system, the wheel to be tested is mounted on the hanger bracket system, so that the dynamic load of the wheel to be tested in the driving process of the vehicle in the vertical direction is stimulated by exerting perpendicular drive on the hanger bracket system.The first drive device drives the revolving drum, drive and loading of the torque of the wheel to be tested are achieved, the complex dynamic load of the wheel in the vertical direction is represented through the hanger bracket system, targeted to the characteristic of complex dynamic load of an off-road vehicle, the stress of the wheel passing through complex cross-country road conditions is stimulated, and the straight travel working condition of wheels of the off-road vehicle is effectively stimulated.

Description

technical field [0001] The invention relates to the technical field of vehicle testing, in particular to a wheel road simulation test bench. Background technique [0002] The existing wheel drum test bench is only equipped with a driving device at the drum, that is, the wheel in contact with the drum can only be driven to rotate by driving the drum to rotate, thereby detecting the corresponding performance parameters of the wheel and indirectly simulating the driving time of the vehicle. The state of the wheels, but for the actual vehicle driving state, the wheels are rolling forward on the road, so the simulation method of the test is different from the actual situation, resulting in deviations between the test results and the actual vehicle conditions. While the vehicle road simulation test bench can apply vertical variable loads to the wheels during the experiment, but it cannot apply longitudinal loads to the wheels, and the wheels cannot rotate during the experiment; th...
