Embodiment Construction

[0030] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0031] Such as Figure 1 to Figure 4As shown, according to an embodiment of the present invention, an axle steering system includes a front axle linkage 10, a rear axle linkage 20, a steering release mechanism 30 and an alignment cylinder 50, wherein the front axle linkage 10 and the rear axle linkage The system 20 is fixedly connected to the frame body 40 . The front axle linkage 10 mainly controls the steering action of the front axle and is connected with the steering wheel. When the vehicle turns, the steering wheel can be used to manipulate the front axle rod system 10 to turn, and the front axle rod system 10 can drive the movement of the rear axle rod system 20 to realize the normal steering...

Abstract

The invention provides a vehicle axle steering system, a control method thereof, and an engineering vehicle. The vehicle axle steering system comprises a front axle lever system, a rear axle lever system and a steering unlocking mechanism, wherein the front axle lever system and the rear axle lever system are fixedly connected onto a frame body; and the steering unlocking mechanism is connected between the front axle lever system and the rear axle lever system, and is provided with a first operating position for enabling the front axle lever system and the rear axle lever system to be locked to form linkage, and a second operating position for enabling the front axle lever system and the rear axle lever system to unlock. The vehicle axle steering system also comprises an alignment oil cylinder, wherein a first end of the alignment oil cylinder is hinged on the frame body; a second end of the alignment oil cylinder is connected with the rear axle lever system; and the alignment oil cylinder is provided with a first operating state for providing a locking force to the rear axle lever system, a second operating state for providing aligning force to the steering mechanism, and an idle state dropping out of steering control. According to the vehicle axle steering system, the problems that in the prior art, the lever system has a single steering mode and poor operation stability can be solved.

Description

technical field [0001] The invention relates to a vehicle steering control system, in particular to an axle steering system, a control method thereof, and an engineering vehicle. Background technique [0002] Engineering vehicles are currently developing in the direction of multi-axle heavy loads, and the vehicles put forward higher requirements for the steering system: on the one hand, the steering system is closely related to the safety of the vehicle, and safety, reliability, and driving comfort have always been the goals pursued by the steering system; on the other hand, Due to the different driving states and different working spaces of construction vehicles, the steering system is required to have a multi-mode switching function. [0003] At present, the steering types used in construction vehicles mainly include rod-connected hydraulic power-assisted steering and electro-hydraulic control steering. [0004] When lever system steering is used in multi-axle vehicles, t...
