Embodiment Construction

[0039] 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.

[0040] The application provides a dual front axle automobile steering system, such as 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, the steering column is driven to rotate, and the steering column drives the steering. The action of the switch to achieve left or right rotation.

[0041] The output shaft of the steering gear is fixedly connected to the upper end of the drop arm 4, and the rotation of the output shaft of...

Abstract

The invention relates to a double-front-axle automobile steering system which comprises a steering device, a plumbing arm, a first front axle straight pull rod, a transition pull rod, a power cylinder assembly, a rocker arm, a second front axle straight pull rod, a first front axle steering knuckle arm, a second front axle steering knuckle arm, a first axle and a second axle. According to the technical scheme, through engaged cooperation of a piston and the rocker arm of the power cylinder, a piston rod and a supporting structure in the prior art are omitted, and through movement of the piston, the rocker arm matched with the piston in a toothed mode rotates left or right to provide power for steering of the second front axle, the power cylinder structure is small in mounting space and meanwhile achieves the effect of a transition rocker arm, and the number of parts in the steering system is decreased. By omitting the piston rod, the power cylinder can bear larger pressure to output larger steering torque, the service life is long, and reliability is good.

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] In the dual front axle steering system, it is necessary to provide steering assistance to the first and second front axles respectively. Generally, the steering gear mainly provides steering assist for the first front axle, and the booster cylinder mainly provides steering assist for the second front axle. The steering gear and the booster cylinder are connected through a dynamic rotation pipeline, which is a parallel structure, and the dynamic oil is pumped between the two sides of the piston. The pressure difference generated on the side generates power assist. [0003] Such as figure 1 As shown, the prior art dual front axle automobile steering system includes a steering wheel 015, a steering column 016, a steering gear 01, a steering gear rocker arm 02, a first front axle strai...
