Abstract
The utility model belongs to the technical field of automotive parts/appliances and particularly relates to a curved tie-rod spherical shell. The curved tie-rod spherical shell disclosed by the utility model comprises a spherical head and a spherical handle, wherein the spherical head is of a cylindrical body, a spherical pin hole which penetrates through the upper and lower end faces of the spherical head is formed in the spherical head, an elliptical sunk part is formed on the upper end face of the spherical head, and the spherical pin hole is located in the middle position of the elliptical sunk part; the spherical handle comprises a crank and a straight handle, wherein one end of the crank is fixedly connected to the external sidewall of the spherical head, the crank and the external sidewall of the spherical head are of circular arc transition, the section of the crank is a concave arc-shaped face, the radian of the concave arc-shaped face is 12-18 degrees, the other end of the crank is fixedly connected with the straight handle, and an arc-shaped connecting plate is arranged at the side part of the straight handle; the central axis of the straight handle is coincided with the radial centerline of the spherical head. The curved tie-rod spherical shell has the advantages that the structure is reasonable and the service time can be prolonged.
Description
Technical field
The utility model belongs to auto parts apparatus technical field, relates in particular to a kind of curved spherical shell of pull rod.
Background technique
Automobile spherical shell is the part belonging in auto parts and components, is mainly used for installing ball pin, plays steering-effecting.Automobile is larger with the material nonhomogeneous hardness between spherical shell and ball pin, long-time rubbing contact, and poor in road conditions especially and Ackermann steer angle ball pin twisting friction automobile spherical shell, causes automobile spherical shell inordinate wear for a long time.Automobile also can make automobile stressed unreasonable with spherical shell with the unreasonable design of spherical shell, and automobile occurs crackle with spherical shell from stress raiser, and prolonged exercise can rupture.
Summary of the invention
The purpose of this utility model is to solve above-described technical problem, provides a kind of rational in infrastructure, can be good at the curved spherical shell of pull rod that extends its service time, and its technological scheme is as follows:
Curved spherical shell of pull rod, it is characterized in that, described curved spherical shell of pull rod comprises bulb and ball handle, described bulb is a cylindrical body, on described bulb, offer the ball pin hole of running through bulb upper and lower end face, bulb upper-end surface is provided with oval depressions portion, and ball pin hole is positioned at the neutral position of oval depressions portion; Described ball handle comprises crank and staight shank, one end of crank is connected and fixed on the outer side wall of bulb, arc transition between crank and the outer side wall of bulb, the section of crank is an indent arc shaped surface, the radian of described indent arc shaped surface is 12-18 degree, the other end of crank is fixed with staight shank, and the sidepiece of described staight shank is provided with arc connecting plate; The central axis of described staight shank overlaps with the radial centre lines of bulb.
Optimal way is that the both sides that are positioned at oval depressions portion on described bulb upper-end surface are provided with symmetrical ear groove.
The curved spherical shell of pull rod that the utility model provides, when in use, bulb is to be connected with ball pin, ball pin is arranged in the ball pin hole of bulb.And the effect of oval depressions portion be make ball pin in ball pin hole, carry out movable in, can effectively increase the activity space of ball pin, increase it and use flexible performance, make the ball pin can be not often in movable and wall friction in the upper-end surface of bulb, thereby reduce the wearing and tearing of bulb and ball pin, extend its service time.The section of crank is an indent arc shaped surface, the radian of described indent arc shaped surface is 12-18 degree, can be so that crank reduces its stress performance in stressed by indent arc shaped surface, make the connection between crank and bulb more stable, and be that 12-18 just can achieve the above object while spending at radian.The sidepiece of staight shank is provided with arc connecting plate, and arc connecting plate can well connect other automobile components.The central axis of described staight shank overlaps with the radial centre lines of bulb, makes the stability of whole curved spherical shell of pull rod better, and ball pin and curved spherical shell of pull rod are also more laborsaving when using.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Embodiment
Below in conjunction with Fig. 1, illustrate embodiment:
As shown in Figure 1, curved spherical shell of pull rod, described curved spherical shell of pull rod comprises bulb 1 and ball handle 2, described bulb 1 is a cylindrical body, on described bulb 1, offer the ball pin hole 3 of running through bulb 1 upper and lower end face, bulb 1 upper-end surface is provided with oval depressions portion 4, and ball pin hole 3 is positioned at the neutral position of oval depressions portion 4; Described ball handle 2 comprises crank 5 and staight shank 6, one end of crank 5 is connected and fixed on the outer side wall of bulb 1, arc transition between the outer side wall of crank 5 and bulb 1, the section of crank 5 is an indent arc shaped surface, the radian of described indent arc shaped surface is 12-18 degree, the other end of crank 5 is fixed with staight shank 6, and the sidepiece of described staight shank 6 is provided with arc connecting plate 7; The described central axis of staight shank 6 and the radial centre lines of bulb overlap.
Optimal way is that the both sides that are positioned at oval depressions portion 4 on described bulb 1 upper-end surface are provided with symmetrical ear groove 8.
The curved spherical shell of pull rod that the utility model provides, when in use, bulb is to be connected with ball pin, ball pin is arranged in the ball pin hole of bulb.And the effect of oval depressions portion be make ball pin in ball pin hole, carry out movable in, can effectively increase the activity space of ball pin, increase it and use flexible performance, make the ball pin can be not often in movable and wall friction in the upper-end surface of bulb, thereby reduce the wearing and tearing of bulb and ball pin, extend its service time.
