Embodiment Construction

[0009] Such as figure 1 As shown, a vehicle steering assist device of the present invention includes a steering pump, a steering gear 1 , a booster cylinder 5 , a booster cylinder support 6 and a right steering knuckle arm 4 .

[0010] Steering gear 1 adopts four oil port steering gear 1, and an oil inlet of steering gear 1 is connected with steering pump oil outlet, and an oil outlet of steering gear 1 is connected with oil pot oil inlet. The output shaft of the steering gear 1 is fixedly connected with an end of the drop arm by a spline, and the other end of the drop arm is hinged with an end of the steering straight tie rod 2, and the other end of the steering straight tie rod 2 is hinged with the left steering knuckle arm 3. Another oil inlet of the steering gear 1 is connected with the oil outlet of the booster cylinder 5, and another oil outlet of the steering gear 1 is connected with the oil inlet of the booster cylinder 5. The piston rod of the booster cylinder 5 is h...

Abstract

The invention relates to a vehicle steering assist device, comprising a steering pump, a steering engine (1), an assist cylinder (5), an assist cylinder support (6), a left steering knuckle arm (3) and a right steering knuckle arm (4); the steering engine (1) is a four-port steering engine (1), two oil inlets of the steering engine (1) are connected to an oil outlet of the steering pump and an oil outlet of the assist cylinder (5) respectively, an output shaft of the steering engine (1) is fixedly connected to one end of a plumbing arm, the other end of the plumbing arm is hinged to one end of a steering drag link (2), the other end of the steering drag link (2) is hinged to the left steering knuckle arm (3), another oil outlet of the steering engine (1) is connected to an oil inlet of the assist cylinder (5), and a piston rod of the assist cylinder (5) is hinged to one end of the right steering knuckle arm (4). The front axle load that a steering system can bear is increased effectively, the bearing capacity problem of the steering system is solved effectively, and the steering assist is provided for a single-steering front axle.

Description

technical field [0001] The invention belongs to the technical field of vehicle steering systems, and in particular relates to a steering assist device for vehicles. Background technique [0002] The existing single-steering front axle vehicle adopts hydraulic power steering, and the hydraulic power steering system includes a steering pump, a steering gear 1 and an oil pot. When the car needs to turn, the driver applies a steering torque to the steering wheel. The torque is transmitted to the steering gear through the steering shaft. The steering pump generates hydraulic power through the engine. The straight tie rod 2 is transmitted to the left steering knuckle arm 3, so that the left steering knuckle arm 3 and the left steering wheel supported by it are deflected. [0003] In recent years, with the development of heavy vehicles, heavy vehicles carry more and more bodywork equipment, and the load on the front axle is increasing. The existing hydraulic power assist system ca...
