Abstract
The utility model provides a bulb and connection that pull rod spherical shell for motor vehicle, 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 well upper portion in axial pore is provided with the shrink pore, 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 at least one through -hole on ball shank's straight shank, shrinkage hole upper portion pore in the axial pore is the toper pore, and the lower part pore is the straight hole way of circular arc pore transition, and the length in lower part pore is greater than the length in upper portion pore, through -hole direction on the straight shank is the same or perpendicular to the direction in pore with the column axon, 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 automobile-use spherical shell of pull rod, 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 automobile-use spherical shell of pull rod of service efficiency.
The purpose of this utility model has been come by following technical solution, a kind of automobile-use 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 the middle and upper part of described axial channel is provided with shrinks duct; One sidewall of described bulb is connected to a ball handle be 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, and the staight shank of ball handle is provided with at least one through hole.
Duct, shrink hole top in described axial channel is tapering passage, and duct, bottom is the straight hole road of circular arc duct transition, and the length in duct, bottom is greater than the length in duct, top; Through hole direction on described staight shank is identical with the direction of column axial channel.
Described arc crank is that body of rod bending forms, and this arc crank and cylinder staight shank are connected with arc-shaped transition and form one; The column of described bulb is a bullet shunk to respective outer end in low-angle centered by bulge loop outside centre.
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 automobile-use 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 the middle and upper part of described axial channel 3 is provided with shrinks duct 4; One sidewall of described bulb 1 connects the ball handle 2 be made up of one section of arc crank 5 and a bit of staight shank 6, and the center of the longitudinal center line of staight shank 6 and column bulb 1 is on same straight line, and the staight shank 6 of ball handle 2 is provided with at least one through hole 7.
Shown in figure, the duct, top, contraction duct 48 in described axial channel 3 is tapering passage, and duct, bottom 9 is the straight hole road of circular arc duct transition, and the length in duct, bottom 9 is greater than the length in duct, top 8; Through hole direction on described staight shank 6 is identical with the direction of column axial channel 3 or vertical.
Arc crank 5 described in the utility model forms for body of rod bending, and this arc crank 5 and cylinder staight shank 6 are connected with arc-shaped transition and form one; The column of described bulb 1 is a bullet 10 shunk to respective outer end in low-angle centered by bulge loop outside centre or middle and upper part.
