Embodiment Construction

[0013] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0014] Such as figure 1 As shown, the present invention is based on the single-drive four-wheel steering mechanism of screw rod and nut, including motor 1, screw rod 2, traversing rod 3, left front wheel 4, left front near V-shaped steering arm 5, front axle 6, right front near V-shaped steering Arm 7, right front wheel 8, front tie rod 9, rear tie rod 10, right rear wheel 11, right rear nearly V-shaped steering arm 12, rear axle 13, left rear nearly V-shaped steering arm 14, left rear wheel 15. There is a boss 17 in the middle of the traverse rod 3, and the boss 17 has a through screw hole 16, the screw hole 16 cooperates with the screw rod 2, and the output shaft of the motor 1 is fixedly connected with the screw rod 2, as figure 2 shown.

[0015] The traversing rod 3 is arranged longitudinally, the front axle 6, the rear...

Abstract

The invention discloses a single-drive four-wheel steering mechanism based on a screw and a nut. The single-drive four-wheel steering mechanism comprises an electromotor, the screw, a transverse bar arranged longitudinally, and a front shaft, a rear shaft, a front tie rod and a rear tie rod which are arranged horizontally, wherein the transverse bar is located between the front tie rod and the rear tie rod; an output shaft of the electromotor is connected with the screw; the screw is matched with a screw hole formed in the transverse bar; sliding chutes are respectively formed in two ends of the transverse bar and respectively sleeve limit rods in the middles of the front tie rod and the rear tie rod; two ends of the front tie rod and the rear tie rod are respectively hinged to an approximate V-shaped steering arm; the other ends of the four approximate V-shaped steering arms are respectively and fixedly connected with axles of four wheels; the four approximate V-shaped steering arms are respectively hinged to two ends of the front shaft and the rear shaft at bending parts of the arms; the front shaft and the rear shaft are fixed on a car frame. The power adopted by the steering mechanism is input from the middle part, so that all components are stressed uniformly, the four wheels are steered simultaneously, the turning radius is shortened, and the flexibility of turning is improved.

Description

technical field [0001] The invention relates to a vehicle steering mechanism, in particular to a single-drive four-wheel steering mechanism of a vehicle based on a screw nut. Background technique [0002] When the vehicle is turning, if only the front wheels are steering, the turning radius is relatively large, and large vehicles such as trucks have a long body and a large inner wheel difference, and there will be a dangerous area where the visual blind spot is located. In logistics management, some vehicles need to turn flexibly and reduce the turning radius. [0003] But do not find the relevant report that utilizes the transmission mode of screw nut to drive four-wheel steering as yet. Contents of the invention [0004] The purpose of the present invention is to provide a single-drive four-wheel steering mechanism based on a screw nut, so as to realize the simultaneous steering of four wheels, shorten the turning radius, and improve the turning flexibility of the vehic...
