Abstract
The utility model provides a bulb and connection that drag link ball shell, it is mainly installed by a supporting car ball round pin that is used for the ball shank of bulb constitutes, the bulb be offering in the middle of one the column body in axial pore, the heavy -calibre straight hole that the transition of circular arc passageway is passed through by small -bore straight hole in upper portion and lower part in the axial pore is formed, a lateral wall of bulb meet have one be in with column body bulb horizontal plane on, the ball shank that constitutes by one a section arc crank and a segment straight shank, and on the center of the axial direction line of straight shank and column body bulb is in same straight line, be provided with the connecting portion to one side evagination on ball shank's straight shank, the upper portion of bulb is an arc end face's lid form, the cone shape that contracts in its below is, and transversal shape of face is like the shape of a hoof, the length of lower part heavy -calibre straight hole is greater than the length of the small -bore straight hole in upper portion, it has rational in infrastructurely, compact, and is wear -resisting, uses simple to operate, can prolong its life, improves characteristics such as availability factor.
Description
Technical field
The utility model relates to a kind of spherical shell of pull rod of automobile-use, belong to automobile accessories parts technical field.
Background technology
Automobile spherical shell of pull rod is mainly used for supporting installation ball pin on automobile, plays motor turning connection function.In prior art, the material nonhomogeneous hardness between the spherical shell of pull rod of automobile and ball pin is comparatively large, long-time wipe contact, especially at road conditions difference and Ackermann steer angle ball pin twisting friction automobile spherical shell of pull rod, causes automobile spherical shell of pull rod inordinate wear for a long time.The unreasonable design of automobile spherical shell of pull rod also can make automobile spherical shell of pull rod stressed unreasonable, and automobile spherical shell of pull rod occurs crackle from stress raiser, and prolonged exercise can rupture.
Summary of the invention
The purpose of this utility model is the deficiency overcoming prior art existence, and provides a kind of rational in infrastructure, compact, easy to install and use, can extend its service life, improve the spherical shell of pull rod of the automobile-use of service efficiency.
The purpose of this utility model has been come by following technical solution, a kind of spherical shell of pull rod, it is supporting for the automobile ball pin bulb installed and the ball handle composition being connected described bulb primarily of one, described bulb is the column offering axial channel in the middle of, and described axial channel consists of the heavy caliber straight hole of circular arc channel transition the small-bore straight hole in top and bottom; One sidewall of described bulb be connected to one be in on column bulb Transverse plane, the ball handle that is made up of one section of arc crank and a bit of staight shank, and the center of the longitudinal center line of staight shank and column bulb is on same straight line, the staight shank of ball handle is provided with the connecting portion to side evagination.
The top of described bulb is the lid shape of a curved end, the cone shape for inside contracting below it, and cross-sectional plane shape is as the shape of a hoof; The length of bottom heavy caliber straight hole is greater than the length of the small-bore straight hole in top.
Described arc crank is formed by the body of rod bending of profiled-cross-section, and this arc crank and cylinder staight shank are connected with arc-shaped transition and form one
The utility model has rational in infrastructure, compact, wear-resisting, easy to install and use, can extend its service life, improves the features such as service efficiency.
Accompanying drawing explanation
Fig. 1 is side-looking structural representation of the present utility model.
Fig. 2 is plan structure schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail: shown in Fig. 1,2, a kind of spherical shell of pull rod described in the utility model, it forms with the ball handle 2 being connected described bulb primarily of a supporting bulb 1 for automobile ball pin installation, described bulb 1 is the column offering axial channel 3 in the middle of, and described axial channel 3 consists of the heavy caliber straight hole 5 of circular arc channel transition the small-bore straight hole 4 in top and bottom; One sidewall of described bulb 1 be connected to one be in on column bulb Transverse plane, the ball handle 2 that is made up of one section of arc crank 6 and a bit of staight shank 7, and the center of the longitudinal center line of staight shank 7 and column bulb 1 is on same straight line, the staight shank 7 of ball handle 2 is provided with the connecting portion 8 to side evagination.
Shown in figure, the top of described bulb 1 is the lid shape 9 of a curved end, the cone shape 10 for inside contracting below it, and cross-sectional plane shape is as the shape of a hoof; The length of bottom heavy caliber straight hole 5 is greater than the length of the small-bore straight hole 4 in top.
Arc crank 6 described in the utility model is formed by the body of rod bending of profiled-cross-section, and this arc crank 6 and cylinder staight shank 7 are connected with arc-shaped transition 11 and form one.
