A kind of electric vehicle wheel hub assembly structure

Abstract

The invention relates to an assembly structure of an electric vehicle wheel hub, comprising a coaxial outer hub 1 and an inner hub 2, spokes are fixed at intervals in the circumferential direction between the outer hub 1 and the inner hub 2, and at the same time, there is a coaxial opening on the inner side of the outer hub 1. The outer slideway 11 is coaxially provided with an inner slideway 21 on the outer side of the inner hub 2, and a slider one 12 is embedded in the outer slideway 11, and a slider two 22 is embedded in the inner slideway 21. A connecting rod assembly 4 is installed between 12 and the second slider 22, the length of the connecting rod assembly 4 can be adjusted in the radial direction of the wheel hub, and a counterweight ring 10 is sleeved on the connecting rod assembly 4, and the counterweight ring 10 is along the The length direction of the connecting rod assembly 4 is slid or fixed, wherein the first slider 12 and the second slider 22 can adopt a block structure, wherein the weight ring can be adjusted around the center of the wheel hub and moved radially, so as to facilitate adjustment and reduce eccentricity force, saving time and manpower.

Description

technical field [0001] The invention relates to the technical field of wheel hubs, in particular to an electric vehicle wheel hub assembly structure. Background technique [0002] The wheel hub is the rotating part of the wheel core connected by the inner profile of the tire through the column, that is, the metal part that supports the center of the tire and is mounted on the shaft. [0003] The structure of the existing wheel hub includes the outer hub, the spokes and the inner hub arranged sequentially from the outside to the inside. The outer side of the outer hub is used to install rubber tires. For connection to the torque output. [0004] There are following defects in the above-mentioned prior art scheme: [0005] In the actual processing process, there are dimensional errors in each component, resulting in eccentric force in the rotation of the wheel hub. In order to eliminate or reduce the influence of eccentric force, most of the wheel hubs are eccentrically weld...

Problems solved by technology

[0005] In the actual processing process, there are dimensional errors in each component, resulting in eccentric force in the rotation of the wheel hub. In order to eliminate or reduce the influence of eccentric force, most of the wheel hubs are eccentrically welded with balance weights, but if the balance weight still exists after welding Larger eccentric force requires removal of the balance weight and re-welding installation, resulting in time-consuming and labor-intensive processing for adjusting the rotation stability of the wheel hub
