In a saddle riding vehicle including: a sprocket driven by a power transmission member; a sprocket support member that supports the sprocket and that is connected with a wheel; a damper member that is housed in a recessed portion in a hub of the wheel and disposed between the hub and the sprocket support member, the damper member being deformed through a relative rotation between the hub and the sprocket support member; and a resistance mechanism that dampens the relative rotation between the hub and the sprocket support member, the sprocket support member includes an extension portion that covers an outer periphery of the hub from an outside in a radial direction, and the resistance mechanism is disposed between an inner periphery of the extension portion and the outer periphery of the hub.

Provided is an intelligent electric wheel hub which belongs to the field of bicycle parts. Two ends of a cylindrical wheel hub housing (2) of the electric wheel hub are respectively connected to a wheel hub left end cover (25) and an outer flywheel ring (7) of a flywheel mechanism to form an inner cavity for integrating and accommodating a gear motor, a battery pack and a controller panel. The intelligent electric wheel hub is highly integrated and is energy-saving and environmentally friendly

This invention discloses a novel product of a Wheel Hub Assembly for damping and noise reduction. It absorbs vibration and noise of brake rotor and brake drum in the braking process by changing flange face structure as well as adding damping coating. During the production, the flange face of the Wheel Hub Assembly is equipped with one or several technical groove(s) while a damping coating is designed to reduce vibration and noise. The damping coating is made of rubber materials, composite materials, damping coating materials or high polymer materials. In this invention, the damping coating is added between wheel hub and brake disk or brake drum. This can not only absorb a part of noise, but also reduce braking vibration to decrease the noise.

An assembly to secure a disc brake rotor to a wheel hub utilizing spring pins and a retaining ring is provided. A partial keyway is formed in the rotor, and a partial keyway is formed in the wheel hub. The rotor is fitted over an inwardly extending section of the hub, with the partial keyways in the rotor and in the wheel hub being aligned to form complete keyways. The spring pins are then press fit into the completed keyways. Finally, a retaining ring is installed into a slot formed in the inwardly extending section of the wheel hub to complete the assembly of the disc brake rotor assembly.

A lug drive system for a wheel such as that found on a motorcycle. The lug drive system includes a 2-piece lug drive hub assembly mourned on one side of the wheel to apply a driving force thereto. The lug drive hub assembly includes a lug drive sprocket and a hub that are detachably connected together by an inner retaining ring. The lug drive sprocket includes an outer drive ring and an inner carrier disk that are detachably connected together by an outer retaining ring. The lug drive system also includes a 2-piece lug drive rotor assembly mounted on the opposite side of the wheel to apply a braking force thereto. The lug drive rotor assembly includes a lug brake rotor and a hub that are detachably connected together by an inner retaining ring. The lug brake rotor includes an outer friction ring and an inner carrier disk that are detachably connected together by an outer retaining ring.
