front wheel steering mechanism

Abstract

The invention provides a front wheel steering mechanism of a vehicle. The steering mechanism comprises a front supporting beam, a fixing rod, a movable rod, a mounting frame and an elastic element, wherein the fixing rod is matched with the inner wall of the front supporting beam through an upper thrust bearing and a lower thrust bearing, and the upper end part of the fixing rod extends into the outer part of the front supporting beam to form a connecting part which is vertically connected with a handle; the movable rod is positioned at the lower end part of the fixing rod, is matched with the fixing rod through a spline, and is matched with the inner wall of the supporting beam through a linear bearing; the mounting frame is fixed at the lower end part of the movable rod, and the front wheel of the vehicle is pivoted on the mounting frame; the elastic element is mounted between the mounting frame and the front supporting beam, and is used for providing the elastic stress for abutting the front supporting beam to the direction away from the mounting frame. The steering mechanism disclosed by the invention utilizes the upper thrust bearing and the lower thrust bearing to offer upward or downward thrust to the fixing rod, and the mounting stability of the fixing rod and the front supporting beam can be ensured; and at the same time, the movable rod can move in the axial direction relative to the fixing rod, and the elastic element can be utilized to realize the damping of the front wheel of the vehicle, so that the comfort is improved.

Description

technical field [0001] The invention relates to a front wheel steering mechanism. Background technique [0002] The front wheels of traditional bicycles or electric vehicles are usually installed on the front fork, the upper end of the front fork is used to connect with the handlebar standpipe, the handlebar standpipe is fixed with the frame, and the front wheel can be turned by turning the handlebar. Thereby realizing the steering of bicycle or electric vehicle, this traditional steering mechanism does not have the effect of shock absorption, and in actual use, it just relies on the flexible tire to realize shock absorption, therefore, its shock absorption effect is relatively poor, comfortable Sex is lower. Contents of the invention [0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a front wheel steering mechanism, which can not only realize the flexible rotation of the handlebar, but also enhance the shock absorpt...
