Embodiment 1

[0021] This embodiment provides a hub assembly, which includes a hub and a power generating device.

[0022] The power generating device includes a base, a sliding column, a gear and a generator;

[0023] One end of the base is fixed on the rim of the hub and is arranged along the radial direction of the hub, a through hole is opened on the base along the axial direction, and the sliding column is slidably arranged on the The sliding column is guided through the side wall of the through hole. In this embodiment, the cross section of the through hole is non-circular, such as square or elliptical, and more preferably, the cross section of the through hole may be square.

[0024] A spring is arranged in the through hole of the base, one end of the spring is set on the bottom wall of the through hole of the base, and the other end is set on the end of the sliding column located in the base , Moreover, the spring is in a pre-compressed state, that is, in an initial state, the spr...

Abstract

The invention discloses a hub assembly. The hub assembly comprises a hub and a power generation device. The power generation device comprises a base, a sliding column, a gear and a generator, whereinone end of the base is fixed to a rim of the hub, a through hole is formed in the base in the axis direction of the base, the sliding column is slidably arranged in the through hole, a rack is formedon the outer wall face of the sliding column, and the rack is matched with the gear; a rotating shaft is rotationally arranged on the base, and the gear is rotationally arranged on the rotating shaftthrough an overrun clutch; a machine base of the generator is fixed to the base, and a rotor of the generator is connected with the end, located outside the base, of the rotating shaft. When the hub assembly is used, in the running process of a vehicle, the generator can rotate and generate electricity, and electric energy is supplied to a tire pressure monitoring device, so that the situation that a battery of the tire pressure monitoring device is replaced is avoided.

Description

technical field [0001] The invention relates to a vehicle component, in particular to a wheel hub assembly. Background technique [0002] With the development of vehicle electronic technology, the tire pressure monitoring system has become one of the configurations of many cars. However, when the tire pressure monitoring system is working, it needs to consume a certain amount of power. Although many tire pressure monitoring devices are designed to save power, it is unavoidable to replace the battery. Contents of the invention [0003] The object of the invention is a wheel hub assembly comprising a power generating device which can be electrically connected to a tire pressure monitoring device so that the battery of the tire pressure monitoring device does not need to be replaced. [0004] The present invention adopts the following technical solutions to solve the technical problems: a hub assembly, which includes a hub and a power generating device; [0005] The power g...
