Knuckle bearing structure of mechanical elastic wheel

Abstract

The invention provides a knuckle bearing structure of a mechanical elastic wheel. The knuckle bearing structure of the mechanical elastic wheel comprises a plurality of high-speed knuckle bearings connected with one another. Each high-speed knuckle bearing comprises an outer ring shell and an inner ring arranged in the outer ring shell, wherein the inner side of the outer ring shell is a concave spherical surface, the outer side of the inner ring is a convex spherical surface, a plurality of annular rolling ways are arranged on the convex spherical surface of the outer side of the inner ring and matched with the concave spherical surface of the inner side of the outer ring shell to form rolling ways, and balls are densely distributed on the rolling ways. According to the knuckle bearing structure of the mechanical elastic wheel, original sliding friction between hinge sets is changed to be rolling friction of the high-speed knuckle bearings, so that the friction energy loss in the wheel is reduced and the high-speed service life of the wheel is prolonged. When the mechanical elastic wheel rotates, the high-speed knuckle bearing structure can rotate freely, flexible bending is achieved, the friction energy loss in the wheel is reduced accordingly, vibration and noise caused by hinge impact are avoided, and riding comfort is improved.

Description

technical field [0001] The invention relates to the field of mechanical elastic wheels, in particular to a high-speed joint bearing structure applied to mechanical elastic wheels. Background technique [0002] For the existing mechanical elastic wheels, the structure of the hinge group is generally adopted. However, the internal friction of the hinge is relatively large, especially when the mechanical elastic wheel rotates at high speed, the sliding friction of the hinge will consume part of the capacity, resulting in unnecessary losses. In addition, during the rotation of the mechanically elastic wheel, there will be a problem of interference of the hinge group, which will have an adverse effect on the ride comfort of the vehicle. [0003] The emergence of high-speed joint bearings provides a new idea for solving the above problems. The structure of the high-speed joint bearing includes an outer ring shell, balls, inner ring, and sealing cover. The inner side of the outer ...
