Problems solved by technology

For example, the patent (CN203719922U) proposes a double-drum energy recovery tire friction and slip stiffness characteristic test device, but it can be seen from its test device that it is only suitable for ordinary car tires, not for road wheels
[0004] The contact distance between the road wheel and the driving drum needs to be adjusted by an adjustment mechanism. Although the patent (CN102401745A) proposes a road surface simulation device for the inner and outer drums with equal diameters, there is no device for adjusting the relative position between the tire and the drum.
[0005] The drum drive test bench of ...

Abstract

The invention discloses a load wheel test device with an elastic damping element and an induction tooth arc base. The device comprises a fixed frame (11) and a load wheel component. A motor (17) is mounted on the fixed frame (11). The output shaft of the motor (17) is connected with a drive wheel hub (1). The motor (17) drives the drive wheel hub (1) to rotate. The drive wheel hub (1) is near one side of the fixed frame (11), and protrudes from the edge of the side. An arc base (10) with induction teeth is arranged on the circumferential surface of the drive wheel hub (1). The load wheel component includes a load wheel (2) mounted on one side of the surface of the drive wheel hub (1). With the device adopted, the characteristic, durability and other performances of the load wheel under a simulated actual condition can be tested. Rotary shock absorbers with different damping forces can be selected and used together with a torsion bar spring to simulate the dynamic force applied to a load wheel on an actual vehicle and to reduce the vibration during test.

Description

technical field [0001] The invention belongs to the field of vehicles and relates to a load wheel test device with an elastic damping element and an arc-shaped base of induced teeth. Background technique [0002] The road wheel is the supporting and moving part of the tracked vehicle. The connection between the road wheel and the car body is through a balance elbow, and a torsion bar spring and a rotary shock absorber are connected to the balance elbow. Since special vehicles are driven in harsh road conditions such as mountainous areas, the reliability of the durability of the road wheels is high. [0003] The road wheel is different from the rubber tire of ordinary cars. The structure of the road wheel uses a two-petal composite hub. The drum is bonded with a non-pneumatic rubber layer, which is in contact with the inner side of the track and does not directly contact the road. For example, the patent (CN203719922U) proposes a double-drum energy recovery tire friction and...
