Abstract
A kind of novel steering dust cover cooperation sealing structure, including dust cover, the front end of the dust cover and the contact position of steering shaft are equipped with several lips, and groove is equipped between adjacent lip, and the lip and steering shaft are interference fits, and the lip is that line contacts with steering shaft.The novel steering dust cover cooperation sealing structure of the utility model is equipped with lip at the cooperation of dust cover and steering shaft, and lip becomes line by face contact before with steering shaft cooperation and contacts, and reduces frictional force；Groove is formed between adjacent lip, groove structure can save the grease for applying and wiping, and extend grease and use the time；Lip size, which is less than, turns to shaft diameter, increases leakproofness.
Description
Technical field
The utility model relates to motor turning axis dust seal technical field, specifically a kind of novel steering dust cover is matched
Close sealing structure.
Background technique
It turns to dust cover and is installed in front panel and be used to completely cut off because steering shaft is generated from cockpit through enging cabin
Front panel on aperture.Dust cover is divided into 1. steering gear housings and connect with front panel according to both ends connecting portion is unusual herein
There is difference in type, 2. front panels and steering shaft connection type, 3. front panels and tubing string outer cylinder connection type, this three types
Defect also has the 1st and 3 to be applied in combination because vehicle space and arrangement are limited on different vehicles and are widely used.
Because by space and apart from the influence factor of arrangement, the 2nd kind of dust cover structure needs one end to be fixed in front panel, separately
Outer open at one end and steering shaft cooperates, and there are relative motions, and the abnormal sound that rubs frequent occurrence, sealing is poor, turns in the presence of damping sense etc.
Problem.
Cooperation at dust cover and steering shaft, there are conflicting for leakproofness and relative motion, and sealing requirements are high, but mistake
The problems such as frictional force becomes larger when small clearance fit will lead to relative motion, generates abnormal sound.At dust cover and steering shaft cooperation
Using new structure, abnormal sound caused by cooperation is solved the problems, such as when not increasing cost and improves leakproofness.
Summary of the invention
The technical problem to be solved by the utility model is to overcome the deficiency of the above-mentioned prior art, a kind of structure letter is provided
Novel steering dust cover cooperation sealing structure that is single, working well.
The utility model is realized with following technical solution: a kind of novel steering dust cover cooperation sealing structure, including
Dust cover, the front end of the dust cover and the contact position of steering shaft are equipped with several lips, and groove is equipped between adjacent lip, described
Lip and steering shaft are interference fits, and the lip is that line contacts with steering shaft.
It is further: the section of the lip is V-shaped, and the tip of the lip is contacted with steering shaft.
The quantity of the lip is 3-4.
The radius of the steering shaft is 12.5mm, the radius 12.25mm of the lip, and total amount of interference is 0.05mm.
The material of the dust cover is rubber.
The utility model has the advantage that the novel steering dust cover cooperation sealing structure of the utility model in dust cover
With lip is equipped at the cooperation of steering shaft, the cooperation of lip and steering shaft becomes line by face contact before and contacts, reduction frictional force；
Groove is formed between adjacent lip, groove structure can save the grease for applying and wiping, and extend grease and use the time；Lip size is small
In turning to shaft diameter, increase leakproofness；And then solve the contradiction of leakproofness and relative motion frictional force.
Detailed description of the invention
Fig. 1 is the overall structure diagram of the utility model；
Fig. 2 is the front-end view of the utility model dust cover；
Fig. 3 is the structural schematic diagram of the utility model dust cover front end and steering shaft cooperation；
In figure: 1, dust cover, 2, lip, 3, groove.
Specific embodiment
A kind of novel steering dust cover as shown in Figure 1 to Figure 3 cooperates sealing structure, including dust cover 1, the dust cover
1 front end and the contact position of steering shaft are equipped with several lips 2, are equipped with groove 3, the lip 2 and steering shaft between adjacent lip 2
It is interference fit, the lip 2 is that line contacts with steering shaft.The radius of the steering shaft is 12.5mm, the radius of the lip 2
12.25mm, total amount of interference are 0.05mm.The position that the dust cover front end of the utility model is contacted with steering shaft is equipped with several lips
Mouthful, lip big end is contacted towards dust cover, small end with steering shaft, and lip becomes line by face contact with steering shaft cooperation and contacts, and is subtracted
Small frictional force；Between lip and steering shaft for interference fit, as steering shaft radius be 12.5mm, lip radius 12.25mm, always
Amount of interference 0.05mm, increases leakproofness；Groove is formed between adjacent lip, the grease for applying and wiping is saved in groove, due to lip
Mouth is interference fit with steering shaft, therefore ensure that the service life of grease and be not easy to leak outside, and total ensure that enough
Leakproofness, dust-proof, waterproof, reduction cabin noise are transferred in cockpit, and will not generate excessive friction and generate steering
Damping sense, and then solve the contradiction of leakproofness and relative motion frictional force.
A kind of novel steering dust cover as shown in Figure 1 to Figure 3 cooperates sealing structure, and the section of the lip 2 is V word
The tip of shape, the lip 2 is contacted with steering shaft.The quantity of the lip 2 is 3-4.The lip of the utility model it is transversal
Face is V-shaped, and the tip of V-shaped is contacted with steering shaft, really realizes line contact；The quantity of lip is at least 3, guarantees storage
The quantity of the groove of grease is no less than two, increases the lubricant effect and service life of grease.
A kind of novel steering dust cover as shown in Figure 1 to Figure 3 cooperates sealing structure, and the material of the dust cover 1 is rubber
Glue.The dust cover of the utility model is rubber material, while guaranteeing dust cover and steering shaft air-tightness, can reduce friction damage
Consumption, improves service life.
