Embodiment Construction

[0041] The technical solution of the present invention is described in detail below through the examples, and the following examples are only exemplary and can only be used to explain and illustrate the technical solution of the present invention, rather than being interpreted as a limitation to the technical solution of the present invention.

[0042] The application provides a dual front axle automobile steering system, such as image 3 with Figure 4 As shown, the upper end of the steering column 2 is connected to the steering wheel 1, and the lower end is connected to the steering gear 3. The steering gear 3 is fixed on the vehicle frame through the steering gear bracket. By turning the steering wheel 1, the steering column 2 is driven to rotate, and the steering column 2 drives the steering gear 3 to move to turn left or turn right.

[0043] The output shaft of the steering gear 3 is fixedly connected to the upper end of the drop arm 4, and the rotation of the output sha...

Abstract

The invention relates to a steering system for a double front axle automobile, comprising a steering gear, a drop arm, a first front axle straight tie rod, a transition tie rod, a booster cylinder assembly, a second axle straight tie rod, a first front axle and a second front axle; The booster cylinder assembly includes the booster cylinder and the rocker arm, and the tooth shape of the booster cylinder and the rocker arm meshes. The booster cylinder of this technical solution cancels the piston rod and supporting structure in the prior art through the meshing and cooperation between the piston and the rocker arm, and through the movement of the piston, the rocker arm that cooperates with the piston tooth shape turns left or right The power cylinder provides power assistance for the steering of the second front axle. The installation space of this power cylinder structure is small, and it also acts as a transitional rocker arm, reducing the number of components in the steering system. By canceling the piston rod, the booster cylinder can withstand greater pressure, thereby outputting greater steering torque, and has a long life and good reliability.

Description

technical field [0001] The invention belongs to the technical field of automobile steering systems, in particular to a double front axle automobile steering system. Background technique [0002] A car with double front axle steering refers to a car with two steering axles. Compared with a single front axle car, there is one more steering axle, so it can carry more load. With the development of the national economy, the double front axle steering car has become a road transport vehicle. development trend. [0003] Such as figure 1 As shown, the prior art dual front axle automobile steering system includes a steering wheel 014, a steering column 015, a steering gear 01, a steering gear rocker arm 02, a first front axle straight tie rod 03, a transition tie rod 05, a transition rocker arm 06, a Second axle straight tie rod 07, first front axle steering knuckle arm 04, second front axle steering knuckle arm 08, first front axle 010, second front axle 011, booster cylinder 09, ...
