Embodiment 1

[0079] Such as figure 1 As shown, the steering transmission system is arranged between two wheel assemblies 1 . The steering transmission system comprises a bogie, a knuckle arm tie rod 3 and a steering knuckle arm 2, and a vertical arm 14 is transmission-connected between the bogie and the knuckle arm tie rod 3, and the vertical arm 14 is rotatably assembled on the vehicle frame; The number is two, and one end of each steering knuckle arm 2 is fixedly connected to the steering knuckle of the corresponding wheel assembly 1, and the other end is hinged to the corresponding knuckle arm tie rod 3, so as to drive the knuckle arm tie rod 3 through the vertical arm 14 when the bogie rotates Drive the steering knuckle arm 2 to move, and then realize the steering of the wheel assembly 1.

[0080] In this embodiment, the bogie includes two steering rods 6, one end of the steering rod 6 is connected to the vertical arm 14, and the other end is hinged to the steering drop arm 8, the ste...

Embodiment 2

[0090] Such as figure 2 As shown, the difference with Embodiment 1 is that the upper rocker arm and the lower rocker arm are not provided on the vertical arm 14, the upper end of the vertical arm 14 is hinged with the steering tie rod 6, and the lower end of the vertical arm 14 is hinged with the joint arm pull rod 3 . In other embodiments, the upper end of the vertical arm and the steering tie rod or between the lower end and the joint arm tie rod can be fixedly connected.

Embodiment 3

[0092] Such as image 3 As shown, the difference from Embodiment 1 is that the two steering rods are replaced by the active rotating arm 15 and the driven rotating arm 16, and a rotating arm pulling rod 17 is arranged between the two driving rotating arms, and the two ends of the rotating arm pulling rod 17 are respectively Hinged on the driving arm 15 and the driven arm 16. Wherein, one end of the driving arm 15 is hinged on the first hinge shaft 18, and the other end is hinged with a transition arm 20, and the transition arm 20 is hinged with the upper rocker arm 5 on the left side; one end of the driven arm 16 is hinged on the second hinge. On the shaft 19, the other end is hinged with a transition arm 20, and the transition arm 20 is hinged with the upper rocker arm 5 on the right side. It should be noted that both the first articulation shaft and the second articulation shaft are fixed on the vehicle frame, and a driving connection part is provided on the active swing ar...

Abstract

The invention relates to a vehicle and a steering transmission system thereof. The steering transmission system comprises a bogie, two steering knuckle arms, knuckle arm pull rods and vertical arms, wherein the bogie is provided with a driving connection part, and the driving connection part is used for being in transmission connection with a steering gear; the two steering knuckle arms are arranged on the two sides of the bogie respectively; the knuckle arm pull rod is arranged between the bogie and the corresponding steering knuckle arm; the knuckle arm pull rod is in transmission connectionwith the bogie through the vertical arm, and the height of the bogie is larger than that of the knuckle arm pull rod, so that the bogie avoids components on the frame; or the vertical arm is in transmission connection between the knuckle arm pull rod and the corresponding knuckle arm, and the height of the knuckle arm pull rod is larger than that of the knuckle arm, so that the bogie avoids components on the frame. The bogie can be lifted to a certain height, layered arrangement of the bogie and the steering knuckle arm is achieved, then the bogie avoids components on the frame, and interference between the bogie and the components on the frame is avoided.

Description

technical field [0001] The invention relates to a vehicle and its steering transmission system. Background technique [0002] The independent suspension usually adopts a disconnected steering trapezoid, and its advantages are: the disconnected steering trapezoid cooperates with the independent suspension of the front wheels, which can ensure that when one side of the wheel jumps up and down, it will not affect the other side of the wheel. [0003] The Chinese patent with the authorized notification number CN201415706Y discloses a steering system for air independent suspension. The steering system includes a steering gear and a steering linkage. The left and right middle rocker arms, middle tie rods and steering straight rods are composed; the left and right middle rocker arms are respectively connected to the chassis through pin shafts. They are respectively connected with the left and right steering knuckle arms and the left and right middle rocker arms with ball joints. T...
