Abstract
The utility model relates to a recirculating ball style hydraulic power assisted steering gear steering nut which comprises a steering nut body arranged in a steering gear assembly. A blocking end of the steering nut is designed in a blind hole mode. A through unloading valve mounting hole is formed in the steering nut. An unloading valve component is arranged in the unloading valve mounting hole. According to the recirculating ball style hydraulic power assisted steering gear steering nut, a through hole of an existing steering nut is changed to an integrated blind hole, a space is reserved for mounting of the unloading valve component, the unloading valve mounting hole is machined, and accordingly an unloading valve is assembled on a recirculating ball style hydraulic power assisted steering gear with a power assisted cylinder diameter of 60-75mm, the problems that light and medium type commercial vehicles with front axle loading below three tons are steered too much, steering gears are high in fault rate, and a cab is lifted are solved, in addition, the integrated blind hole is used, original nut blocking is avoided, cost is lowered, and structure is simple.
Description
Technical field
The utility model relates to a kind of automobile steering device steering nut, more specifically to a kind of circulatory spherical hydraulic power-assisted steering gear steering nut.
Background technology
Circulation ball hydraulic power assisted steering is the product of comparative maturity in the world, is widely used at present on the commercial vehicle/comm..vehicle, and its inner structure not only relates to high-precision mechanical drive, also needs complicated hydraulic technique.Circulation ball hydraulic power assisted steering is not when configuring the stroke unloader valve, in the motor turning process, when the positive stop lug boss on the front-wheel and the caging bolt on the steering swivel were collided, power steering infinitely increased, and hydraulic system pressure rises to the highest, Hydraulic Pump generates heat in a large number, cause the hydraulic work system performance sharply to worsen, steering gear connection bears peak load, reduces greatly the work life of steering swivel system, cause oversteer, the problem of " lifting operator's compartment " occurs simultaneously.
Because the stroke unloader valve has good protective effect to steering swivel system, can significantly improve the service life of steering swivel system, the circulation ball hydraulic power assisted steering that present domestic heavy goods vehicles is assembled all disposes the stroke unloader valve.And the circulation ball hydraulic power assisted steering of the power-assisted cylinder diameter Φ 60mm-Φ 75mm that light, the medium-sized commercial vehicle/comm..vehicle of weight on front axle below 3 tons assembles does not all configure the stroke unloader valve, as shown in Figure 1, major cause is that the steering nut of Φ 60mm-Φ 75mm can't be arranged existing ripe unloader valve, cause oversteer, cause this series deflector fault rate high, and can't solve the problem of " lifting operator's compartment ".
The utility model content
Technical problem to be solved in the utility model is, overcome the shortcoming of prior art, propose a kind of circulatory spherical hydraulic power-assisted steering gear steering nut, efficiently solve oversteer and the high problem of deflector fault rate of light, the medium-sized commercial vehicle/comm..vehicle of weight on front axle below 3 tons.
The technical scheme that the utility model solves above technical matters is: a kind of circulatory spherical hydraulic power-assisted steering gear steering nut is provided, comprise the steering nut of being located in the steering assembly, described steering nut the obstruction end design for blind hole, be provided with the unloader valve mounting hole of perforation at described steering nut, unloading valve component is installed in the described unloader valve mounting hole.
The technical scheme that the utility model further limits is: aforesaid circulatory spherical hydraulic power-assisted steering gear steering nut, described unloader valve mounting hole site is in the top of described blind hole.
Further, aforesaid circulatory spherical hydraulic power-assisted steering gear steering nut, the steering assembly shell that described unloading valve component is corresponding is provided with adjusting hole, on the described adjusting hole adjusting nut is installed.
The beneficial effects of the utility model are: the utility model changes the through hole of original steering nut into the integral type blind hole, installation slot milling for unloading valve component, and process the unloading valve component mounting hole, thereby unloader valve is configured on the circulation ball hydraulic power assisted steering that the servo cylinder diameter is Φ 60mm-Φ 75mm, efficiently solves light, the oversteer of medium-sized commercial vehicle/comm..vehicle of weight on front axle below 3 tons, the deflector fault rate is high and the difficult problem of " lifting operator's compartment "; In addition, adopt the integral type blind hole, save the original nut of part and stop up, reduce cost, structure is simpler.

Fig. 2 is the utility model structural representation.
Fig. 3 is the utility model steering nut structural representation.
The specific embodiment
A kind of circulatory spherical hydraulic power-assisted steering gear steering nut that the present embodiment provides, structure as shown in Figures 2 and 3, comprise the steering nut 1 of being located in the steering assembly, steering nut obstruction end 2 design for blind hole, be provided with the unloader valve mounting hole 3 of perforation at steering nut, unloader valve mounting hole 3 is positioned at the top of blind hole, and unloading valve component 4 is installed in the unloader valve mounting hole; The steering assembly shell 5 of unloading valve component 4 correspondences is provided with adjusting hole, and adjusting nut 6 is installed on the adjusting hole.
In the present embodiment, brand-new design the structure of steering nut, change original through-hole structure the design of into integral type blind hole, installation slot milling for unloading valve component, thereby process the unloading valve component mounting hole, thereby unloading valve component is configured on the circulation ball hydraulic power assisted steering that the power-assisted cylinder diameter is Φ 60mm-Φ 75mm, efficiently solves light, the oversteer of medium-sized commercial vehicle/comm..vehicle of weight on front axle below 3 tons, the deflector fault rate is high and the difficult problem of " lifting operator's compartment ".
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
Claims (3)
1. circulatory spherical hydraulic power-assisted steering gear steering nut, comprise the steering nut of being located in the steering assembly, it is characterized in that: described steering nut the obstruction end design for blind hole, be provided with the unloader valve mounting hole of perforation at described steering nut, unloading valve component is installed in the described unloader valve mounting hole.
