Abstract
The invention discloses a steering pump body structure for preventing sliding of a framework oil seal. A thrust groove is formed in an inner cavity of a pump body and located at the bottom of the framework oil seal. According to the steering pump body structure for preventing sliding of the framework oil seal, the groove is formed at the lower groove framework oil seal position of the inner cavity of the pump body, so that the effect of protecting the framework oil seal is achieved, and the oil leakage phenomenon caused by sliding of the framework oil seal and abrasion of a bearing end is avoided.
Description
Technical field
The present invention relates to automobile steering system power-assisted oil pump field.
Background technology
Hydraulic booster vehicle steering system constantly develops with China's economy, and the fast development of automobile industry, big horse
Force engine heavy duty vehicle is in rising trend, and steering force is gradually increased, and also progressively carries along with the pressure of hydraulic steering pump
Height, the working speed of steering pump is also gradually lifted.And the outside framework oil seal of oil pump shaft end seal can axle when axle is run up
To micro slip, cause it to wear and tear with bearing touch, reduce sealing property, ultimately result in the generation of oil leakage phenomenon.
The content of the invention
For the problems referred to above that the outside framework oil seal for overcoming power assistance pump for steering is present, the invention provides a kind of anti-outside framework oil seal
The steering pump body structure of slip.
The technical scheme that adopted for achieving the above object of the present invention is：The steering pump body knot that anti-outside framework oil seal slides
Structure, the inner chamber of the pump housing 1 is located at the bottom of outside framework oil seal 3 and is provided with thrust groove 4.
The steering pump body structure that the anti-outside framework oil seal of the present invention slides, the position root of groove outside framework oil seal under pump housing inner chamber
Portion slots, so as to play a part of that outside framework oil seal is protected, it is to avoid cause because outside framework oil seal slides and worn and torn with bearing end
Oil leakage phenomenon.
Description of the drawings
Fig. 1 is the steering pump body structure chart that anti-outside framework oil seal of the invention slides.
Fig. 2 is Figure 1A parts amplification assumption diagram.
In figure：1st, the pump housing, 2, main shaft, 3, outside framework oil seal, 4, thrust groove.
Specific embodiment
The steering pump body structure that the anti-outside framework oil seal of the present invention slides is as shown in figure 1, in the inner chamber lower skeleton oil sealing of the pump housing 1
A thrust groove 4 has been opened in 3 position bottom, after oil sealing is pressed into, cylindrical root is pressed onto by the outside framework oil seal 3 of pump housing interior ring compresses
Afterwards, because of the self attributes of elastomeric material, the bottom cylindrical of oil sealing 3 can expand in thrust groove 4, and the edge of thrust groove can hinder skeleton
Oil sealing slides, so as to play a part of that outside framework oil seal is protected, it is to avoid cause because outside framework oil seal slides and worn and torn with bearing end
Oil leakage phenomenon.
Claims (1)
1. the steering pump body structure that anti-outside framework oil seal slides, it is characterised in that：The pump housing（1）Inner chamber is located at outside framework oil seal（3）Bottom
Thrust groove is provided with portion（4）.
