Problems solved by technology

[0008] For mechanical multi-axle steering all-terrain cranes, the shimmy phenomenon of the steering wheel caused by interference steering, insufficient stiffness of the steering rod system, and the connection gap of the guide rod system is particularly serious, which affects the braking performance, handling stability, and ride quality of the crane. Comfort and driving safety, but also increased tire wear and vehicle fuel consumption

Embodiment Construction

[0028] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0029] figure 2 and image 3 The suspension guide mechanism of the all-terrain crane according to the present invention is shown. Such as figure 2 and image 3 As shown, the suspension guide linkage mechanism in the present invention (or simply referred to as the suspension guide mechanism) is composed of two lower thrust rods 1, two upper thrust rods 2 and one steering straight rod 3, and all the linkages are arranged horizontally And the projected length dimensions in the vehicle traveling direction are all equal.

[0030] Two lower thrust rods 1 are arranged parallel and symmetrically according to the center line of the vehicle frame, and are movably connected with the bridge and the vehicle frame body.

[0031] The two upper thrust rods 2...

Abstract

The invention discloses an all terrain crane and a suspension guide mechanism for steering axle and non-steering axle, wherein the suspension guide mechanism for steering axle comprises two lower thrust rods, two upper thrust rods and steering drag rod, which are horizontally arranged and the projection length sizes of them in the vehicle running direction are equal. The suspension guide mechanism for non-steering axle does not comprise steering drag rod. In the invention, by rationally configuring the upper and lower thrust rod and steering drag rod, the projection length sizes of them in the vehicle running direction are equal, so as to improve the motion coordination and stress condition and delay the release of the joint, thereby improving the stability of the operation and comfort and safety of the vehicle.

Description

technical field [0001] The invention relates to a suspension system of a vehicle, in particular to a suspension guide mechanism for an all-terrain crane. Background technique [0002] With the continuous increase of the self-weight of all-terrain cranes, the continuous increase of the number of axles and the continuous increase of vehicle speed, the problems of braking deviation and interference steering caused by the uncoordinated vehicle guiding mechanism have become more and more prominent, seriously affecting the handling stability of the vehicle , ride comfort and driving safety. [0003] Wherein, the term "deviation under braking" refers to that the vehicle cannot keep running in a straight line when braking, and deviates in a certain direction. One of the reasons is the motion interference between the suspension guide bar system and the steering system tie rod. [0004] The term "interference steering" means that when the frame body moves relative to the axle, the s...
