Problems solved by technology

This requires the hub to have better fatigue strength and higher stiffness, but the ensuing problem is that the anti-vibration capacity of the hub is correspondingly reduced, and the vehicle will experience obvious bumps when driving, resulting in a decrease in the NVH performance of the vehicle. even caused a car accident

Embodiment Construction

[0013] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0014] see figure 1 and figure 2 A vibration-damping wheel hub shown includes a rim 1, a hub body 4 located at the center of the rim, and spokes uniformly arranged between the rim 1 and the hub body 4, and the spokes include a hydraulic cylinder 2 and a connecting piece capable of bending and elastic deformation 3. The connecting piece 3 is an arc-shaped long bar, which is arranged at intervals between the hydraulic cylinders 2. The piston rod of the hydraulic cylinder 2 and one end of the connecting piece 3 are connected to the inner side of the rim 1. The hydraulic cylinder The cylinder body of 2 and the other end of connector 3 are all connected with the outside of hub body 4.

[0015] In this example, if image 3 As shown, on the premise that the bending elastic properties of the connector 3 meet the requirements, twisting the middle part of the conne...

Abstract

The invention discloses a vibration-reduction hub which comprises a rim, a hub body and spokes, wherein the hub body is located in the center of the rim; and the spokes are evenly arranged between the rim and the hub body. Each spoke comprises a hydraulic cylinder; a piston rod of each hydraulic cylinder is connected with the inner side of the rim; and a cylinder body of each hydraulic cylinder is connected with the outer side of the hub body. Each spoke further comprises a connecting piece with an elastic deformation function. The connecting pieces are arranged between the hydraulic cylinders at intervals. One ends of the connecting pieces are connected with the inner side of the rim. The other ends of the connecting pieces are connected with the outer side of the hub body. According to the vibration-reduction hub, on the basis that rigid spokes of a conventional hub are modified to be provided with the flexible hydraulic cylinders, the connecting pieces with the elastic deformation function are additionally arranged for the spokes, the impact acting force of road surfaces to the hub is counteracted by the combined action of extensible deformation generated continuously and alternately by the connecting pieces and action of the hydraulic cylinders, accordingly vibration of the hub is further reduced, and the vibration resistance of the hub is improved.

Description

technical field [0001] The invention relates to wheel components, in particular to a wheel hub. Background technique [0002] Usually, the wheel hub is the most important safety component carried by the vehicle. It not only bears the pressure of the vehicle's own weight vertically acting on the wheel hub, but also is subjected to the dynamic torque force when the vehicle starts or brakes, as well as turning and encountering uneven road surfaces during driving. Or by the dynamic alternating stress in different directions such as the impact of road obstacles. This requires the hub to have better fatigue strength and higher stiffness, but the ensuing problem is that the anti-vibration capacity of the hub is correspondingly reduced, and the vehicle will experience obvious bumps when driving, resulting in a decrease in the NVH performance of the vehicle. Even cause a car accident. CN 203945899 U discloses a vibration-damping hub, including an outer circular hub and a central hu...
