Problems solved by technology

[0005] refer to figure 1 , 2 Although the rod body 154 of each connecting rod 153 can make the rotation between the rod body 154 and the mounting seat 151 and the connecting seat 152 more smooth through the joint 155, the joint 155 is as follows: figure 2 The deflection range of the direction shown by the arrow 16 is small (about 22 degrees), not only, causing the steering angle of the front wheel 132 to be limited and unable to carry out large-angle steering (that is, the so-called pressing car), and then jointly affecting the two wheels. front-wheel vehicle 1 maneuverability; and when road bumps cause the connecting seat 152 to produce figure 1 When vibrating in the direction indicated by the middle arrow 17, due to the small deflection range of the joint 155, the joint 155 needs to directly bear the axial load, which greatly shortens the service life of the joint 155

Abstract

The invention provides a steering device for a vehicle with two front wheels. The steering device comprises a plurality of connector units and a plurality of steering connecting rods, wherein the connector units are arranged on a control lever and a suspension unit of the vehicle with two front wheels respectively, and the steering connecting rods are connected with the connector units respectively; at least the connector unit on the control lever comprises a seat body connected to the control lever, a first pivoting mechanism pivoted on the seat body, and a second pivoting mechanism pivoted on the first pivoting mechanism, and the rotating axis of the first pivoting mechanism and the rotating axis of the second pivoting mechanism are orthogonal. The steering angle of the suspension unit can be increased to promote the operability by utilizing the first and the second pivoting mechanism the axes of which are orthogonal, and the impact force is absorbed by utilizing the mode of relative rotation of the first and the second pivoting mechanism, and therefore the whole service life of the steering device is prolonged.

Description

technical field [0001] The present invention relates to a steering device, in particular to a steering device for a vehicle with two front wheels. Background technique [0002] refer to figure 1 The existing two-front-wheel vehicle 1 includes a vehicle frame 11, a central rod 12 pivotally arranged on the front side of the vehicle frame 11, two suspension units 13 respectively located on the left and right sides of the central rod 12, and a pivotally arranged on the front side of the central rod 12. A supporting frame 14 on the frame 11 is connected to the suspension unit 13 , and a steering unit 15 is connected to the frame 11 and the suspension unit 13 . [0003] Wherein, each suspension unit 13 all includes a front fork 131, and a front wheel 132 pivotally arranged on the front fork 131; A connecting base 152 disposed on the front fork 131 of each suspension unit 13 and two connecting rods 153 respectively connecting the mounting base 151 and each connecting base 152 . ...
