Abstract

The invention provides equipment for testing an alternating tangential stress of a vehicle wheel hub. The equipment comprises a motor, a speed reducer, a grooved wheel, an annular groove, a first roller, a second roller, a roller support, a first torsion transmission swinging rod, a second torsion transmission swinging rod, a left compression spring, a right compression spring, a first torsion transmission swinging rod resistance end compression spring seat, a second torsion transmission swinging rod resistance end compression spring seat, a wheel hub torsion bar left compression spring seat, a wheel hub torsion right compression spring seat, and a wheel hub torsion rod. The rollers are placed in the grooved wheel, and the grooved wheel drives the two rollers to move in grooves, thereby achieving the left-right movement. The rollers are connected with the torsion transmission swinging rods, and the two torsion transmission swinging rods take supporting points as the circle centers to swing, thereby enabling front segments to transmit alternating forces to the compression springs. The compression springs enable the forces to be transmitted to a wheel hub through the wheel hub torsion rod. Therefore, the equipment can simulate the conditions that the wheel hub bears an alternating tangential stress during starting, moving and braking.

Description

technical field [0001] The invention relates to a force test device for a vehicle wheel hub, in particular to a vehicle wheel hub alternating tangential stress test device. Background technique [0002] With the development of society, vehicles have become the main tool for people to travel. The safety of vehicles is closely related to people's personal safety. As the main part of the vehicle, the wheel hub bears all the gravity of the vehicle and has different speeds and road conditions. The various alternating forces generated, this gravity and the alternating force will lead to sudden fracture and fatigue fracture of the hub. Once the hub is damaged, the vehicle will fall and be damaged, and personal injury and life-threatening will occur. [0003] The invention patent with application number 201410497095.2 provides a hub unit static strength tester, which can test the actual static load bearing capacity of the hub unit through simulation. This equipment can only test th...
