Description

Steering ball head assembly

Technical Field

The utility model relates to an automobile spare and accessory part field especially relates to a turn to bulb assembly.

Background

The steering ball head is one of key parts of a vehicle steering mechanism, and the mechanism is connected with a longitudinal tie rod or a transverse tie rod, and plays an important auxiliary role in stabilizing a steering system.

People often add lubricating grease in the ball seat and be used for reducing the friction between bulb and the ball seat, however, current bulb is after long-term the use, because impurity gets into the ball seat, can make the surface of the mounting hole of ball seat and bulb cover the mixture of one deck lubricating grease and impurity, makes the surface of bulb take place wearing and tearing easily when rotating, very big influence the performance of bulb, want to clear up these mixtures and must pull down again and turn to the bulb, it is particularly troublesome.

SUMMERY OF THE UTILITY MODEL

The present invention aims at solving at least one of the technical problems in the related art to a certain extent. In view of this, the present invention provides a steering ball head assembly, which has the advantages of reducing the surface wear of the ball head, good heat dissipation, and convenient detachment.

In order to solve the technical problem, the technical scheme of the utility model is that: the utility model provides a steering ball head assembly, includes ball seat and bulb round pin, the bulb round pin includes bulb and the pin rod of being connected with the bulb, the ball seat is equipped with the mounting hole with the bulb adaptation, the bulb sets up in the mounting hole, be equipped with the spherical cap on the ball seat, the spherical cap is equipped with the opening that supplies the pin rod to stretch out, the ball seat passes through bolted connection with the spherical cap, the blind hole has been seted up to the bottom of mounting hole, be equipped with the dysmorphism groove on the diameter position of bulb, the dysmorphism groove is including the flaring portion that is located both ends and the intercommunication portion of connecting the flaring portion.

Preferably, the communication portion is a circular hole.

Preferably, the flared portion comprises a first straight line and a second straight line, and an included angle L formed by the first straight line and the second straight line is 45-100 degrees.

Preferably, the thickness of the flared portion is the same as the aperture of the communication portion.

Preferably, the length of the flared part is 1/5-3/5 of the diameter of the ball head.

The utility model discloses technical effect mainly embodies in following aspect: the valve seat and the valve cover are connected through bolts, and are convenient to disassemble; the blind hole at the bottom of the mounting hole can contain a mixture of lubricating grease and impurities, when the ball head rotates, the mixture of the lubricating grease and the impurities covering the surface of the ball head can be scraped off by the mouth of the blind hole, and the mixture can be gathered in the blind hole; the heterosexual groove can scrape and collect most of lubricating grease and impurity mixtures on the wall of the mounting hole when the ball head rotates, and abrasion of the ball head is reduced.

fig. 2 is a schematic view of the three-dimensional structure of the ball head of the present invention.

Reference numerals: 1. a ball seat; 11. mounting holes; 111. blind holes; 2. a ball stud; 21. a ball head; 211. a special-shaped groove; 2111. a flared part; 2112. a communicating portion; 22. a pin rod; 3. a ball cover; 31. and (4) opening.

Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention so that the technical solution of the present invention can be more easily understood and grasped, and should not be construed as limiting the present invention.

Examples

The utility model provides a steering ball head assembly, refer to fig. 1 and show, the utility model discloses a steering ball head assembly, including ball seat 1 and bulb round pin 2, bulb round pin 2 includes bulb 21 and the pin rod 22 of being connected with bulb 21, ball seat 1 is equipped with the mounting hole 11 with bulb 21 adaptation, bulb 21 sets up in mounting hole 11, be equipped with spherical cap 3 on the ball seat 1, spherical cap 3 is equipped with the opening 31 that supplies pin rod 22 to stretch out, ball seat 1 passes through bolted connection with spherical cap 3, blind hole 111 has been seted up to the bottom of mounting hole 11, be equipped with dysmorphism groove 211 on the diameter position of bulb 21, dysmorphism groove 211 is including the flaring portion 2111 that is located both ends and the intercommunication portion 2112 of connecting flaring portion 2111.

Referring to fig. 2, the communication part is a circular hole, and the structure of the circular hole can enhance the structural strength of the ball head.

Referring to fig. 1, the flared portion 2111 includes a first straight line (a) and a second straight line (b) forming an included angle L of 45-100 degrees. An excessively large angle affects the structural strength of the ball head 21, and an excessively small angle weakens the function of the flared portion 2111 in scraping off the grease and foreign matter mixture.

Referring to fig. 2, the thickness (M) of the flared portion 2111 is the same as the diameter of the communication portion 2112, and the heat radiation capability of the ball 21 can be improved.

Referring to fig. 1, the length (T) of the flared portion 2111 is between 1/5 and 3/5 of the diameter of the ball head 21, and an excessively long flared portion 2111 affects the structural strength of the ball head 21, while an excessively short flared portion 2111 has a reduced effect of scraping off grease and impurities on the inner wall of the mounting hole 11.
