Abstract

The invention relates to a front axle assembly of a vehicle steering system and the vehicle steering system. The front axle assembly of the vehicle steering system comprises a front axle, a first mounting base, a second mounting base, a left steering wheel lower knuckle arm and a right steering wheel lower knuckle arm; the first mounting base is assembled on the bridge shell of the front axle; the first mounting seat is configured as follows: when the electro-hydraulic steering engine is mounted and fixed on the first mounting seat, the clamping angle between the axial direction of the electro-hydraulic steering engine and the height direction of the vehicle is a first acute angle alpha; the second mounting seat is assembled on an axle housing of the front axle and is used for being connected with one end of a booster cylinder; the left steering wheel lower knuckle arm is rotationally connected to the front axle and used for being connected with a steering plumbing arm of the electro-hydraulic steering machine through a straight pull rod. The right steering wheel lower knuckle arm is rotationally connected to the front axle and used for being connected with the other end of the booster cylinder. According to the front axle, the electro-hydraulic steering machine and the power-assisted cylinder are combined for assisting power, and steering under large loads can be achieved.

Description

technical field [0001] The present application relates to the technical field of vehicle front axles, in particular to a front axle assembly of a vehicle steering system and the vehicle steering system. Background technique [0002] At present, unmanned vehicles are more and more widely used. Unmanned vehicles used in industrial parks, ports, and docks are usually flatbed vehicles with large tonnage and no cab. In this type of unmanned flatbed truck, the space above the frame is usually used for loading cargo or top loading. In order to minimize the height of the vehicle after loading cargo, it is usually required that the height of the chassis and frame be as small as possible, and all parts of the chassis All must not exceed the upper plane of the frame. Therefore, this type of chassis usually does not have a steering wheel, and is required to be able to carry the weight of a standard container, usually more than 80 tons. [0003] The front axle assembly provided in some ...
