Embodiment Construction

[0025] The embodiment of the present invention solves the technical problem in the prior art that switching between multiple steering modes cannot be realized by providing a vehicle steering mode switching system.

[0026] The technical solution in the embodiment of the present invention is to solve the above-mentioned problems, and the general idea is as follows:

[0027] The first valve, the second valve and the third valve are connected in series through the first linkage rod to form a group of linkage operations, the fourth valve, the fifth valve and the sixth valve are connected in series into a group of linkage operations through the second linkage lever, and Connect to the front wheel steering cylinder and the rear wheel steering cylinder respectively. Operating the first linkage lever and the second linkage lever can realize the switching of the on-off state of each valve, so as to realize different actions of the front and rear wheel steering cylinders, thereby realiz...

Abstract

The invention discloses a switching system for vehicle steering modes. A first valve, a second valve and a third valve are strung together into a group by a first linkage rod, and a fourth valve, a fifth valve and a sixth valve are strung together into a group by a second linkage rod, and oil ports are connected to a front wheel steering cylinder and a rear wheel steering cylinder respectively. The operation of the first linkage rod and the second linkage rod can realize the switching of the on-off state of each valve, so as to realize the different actions of the front and rear wheel steeringcylinders, thereby realizing the switching between a plurality of steering modes. The switching system has no electrical components, and is low in cost, high in reliability, few in components, simpleand intuitive in operation, compact in structure and high in integration level.

Description

technical field [0001] The invention relates to the technical field of switching systems, in particular to a switching system for vehicle steering modes. Background technique [0002] At present, the steering modes adopted by engineering vehicles mainly include: front-wheel steering, rear-wheel steering and all-wheel steering. The steering mode is mainly determined according to the site and working conditions. The steering mode of a general vehicle is fixed and cannot be changed, and can only be one of three modes: front-wheel steering, rear-wheel steering, and all-wheel steering. [0003] This kind of vehicle cannot realize switching among multi-steering modes, and has great limitations. Contents of the invention [0004] The present invention solves the technical problem in the prior art that switching between multiple steering modes cannot be realized by providing a switching system for vehicle steering modes. [0005] The present invention provides a vehicle steerin...
