Abstract
The utility model relates to a self-adjusting ball head for a vehicle, belonging to a vehicle connecting piece. Because the outer ball surface of a ball head pin is positioned in an inner ball surface of an inner ball surface seat and an outer ball surface seat, by using the pretightening force of a lower sealing regulating spring for a ball head seat, the self-adjusting ball head for the vehicle can automatically eliminate the abrasion gap between the ball head pin and the ball head seat; the service life of the self-adjusting ball head for the vehicle prolongs one time, and a wearing part can be replaced; the utility model has the advantages of simple structure and low cost and is suitable for various vehicles.
Description
A kind of automobile-used self-adjusting bulb, it belongs to the vehicle attaching parts.
No matter existing automobile-used bulb is suspension bulb or steering ball end, mostly is made up of body, ball end, ball cap and rubber boot, and ball cap is a nylon material, and ball end and ball cap are contained in the body, and seal after adding cover plate at the rear portion, and the front portion adds rubber boot.Because after ball end and the wearing and tearing of nylon ball headstock, the ball end pine is spacious, sends abnormal voice when making vehicle operating.This bulb can not be repaired, and service life is short.
The purpose of this utility model is: design a kind of automobile-used self-adjusting bulb, this bulb can be eliminated the wearing clearance between ball end and the ball cap automatically, long service life, and consumable accessory can be changed.
Technical solution of the present utility model is: a kind of automobile-used self-adjusting bulb, it mainly comprises ball end, rubber boot, body and ball cap.Special character of the present utility model is, it also comprises spring, lower seal and oil nozzle, ball cap and outer ball cap in above-mentioned ball cap is divided into, interior ball cap and outer ball cap are equipped with the Internal Spherical Surface that matches with the spherical outside surface of ball end, interior ball cap, ball end, outer ball cap, spring and lower seal are installed in the body successively, the centre hole of ball cap and body stretched to the outside in the pin portion of ball end was passed, rubber boot tightly is enclosed within the pin portion of ball end and the end of our department, and oil nozzle is installed in the outside of lower seal.
Outer ball cap and seal up down and be provided with the centre hole that supplying lubricating grease enters, lower seal and body are by being threaded.
The guiding theory of technique scheme is: the Internal Spherical Surface of ball cap and outer ball cap in the spherical outside surface of ball end places, by lower seal spring is applied predetermincd tension, when wearing and tearing take place in the Internal Spherical Surface of the spherical outside surface of ball end and ball cap, spring can promote ball cap and move the elimination wearing clearance, and oil nozzle can inject grease to the slip sphere.
Effect of the present utility model is: this automobile-used self-adjusting bulb, owing to adopted interior ball cap, outer ball cap, spring and spring applied the lower seal of predetermincd tension, when wearing and tearing take place in the Internal Spherical Surface of the spherical outside surface of ball end and ball cap, spring force can make ball cap move and eliminate wearing clearance, ball end can be because of overheated locking yet in addition, automobile-used self-adjusting bulb is worked under the condition of no gap, makes vehicle operating steadily and not send abnormal voice.This bulb life-span doubles, and consumable accessory can be changed, and is simple in structure, cost is low, and is extremely popular with users.
Description of drawings:
Accompanying drawing 1 is a kind of structural representation of automobile-used self-adjusting bulb.
Be an embodiment of the present utility model below, provide details of the present utility model by description and accompanying drawing to this embodiment.
Fig. 1 is a kind of structural representation of automobile-used self-adjusting bulb.Among the figure, major part is made up of ball end (1), rubber boot (2), body (3), interior ball cap (4), outer ball cap (5), spring (6), lower seal (7) and oil nozzle (8).Interior ball cap (4), ball end (1), outer ball cap (5), spring (6), lower seal (7) are installed in the body (3) successively, lower seal (7) and body (3) are by being threaded, rotate the predetermincd tension of lower seal (7) adjustable springs (6), when the Internal Spherical Surface wearing and tearing of the spherical outside surface of ball end (1) and ball cap, under the effect of spring force, can there be the gap in the bulb sliding part, has guaranteed that the bulb sliding part does not have gap work, and the lubricated of bulb sliding part injects grease by oil nozzle.Rubber boot (2) tightly is enclosed within the pin portion of ball end (1) and the end of body (3), and body (3) is welded on needs bulb bonded assembly one side, and opposite side is connected with ball end (1).Ball cap generally adopts the manufacturing of abrasion resistant spheroidal graphite iron.
Claims (2)
1, a kind of automobile-used self-adjusting bulb, it mainly comprises ball end (1), rubber boot (2), body (3) and ball cap, of the present utility model being characterised in that, it also comprises spring (6), lower seal (7) and oil nozzle (8), above-mentioned ball cap is divided into interior ball cap (4) and outer ball cap (5), interior ball cap (4) and outer ball cap (5) are equipped with the Internal Spherical Surface that matches with the spherical outside surface of ball end (1), interior ball cap (4), ball end (1), outer ball cap (5), spring (6) and lower seal (7) are installed in the body (3) successively, the centre hole that interior ball cap (4) and body (3) pass in the pin portion of ball end (1) stretches to the outside, rubber boot (2) tightly is enclosed within the pin portion of ball end (1) and the end of body (3), and oil nozzle (8) is installed in the outside of lower seal (7).
According to the described automobile-used self-adjusting bulb of claim 1, it is characterized in that 2, outer ball cap (5) and lower seal (7) are provided with the centre hole that supplying lubricating grease enters, lower seal (7) and body (3) are by being threaded.
