Abstract
Provided is a pull rod spherical shell for a vehicle. The pull rod spherical shell for the vehicle is mainly composed of a ball used for installation of a vehicle ball pin in a matched mode and a ball handle connected with the ball, wherein the ball is a columnar body with an axial pore channel in the middle; the middle of the axial pore channel is provided with a shrinkage hole of which the hole diameter is smaller than an upper pore channel and a lower pore channel; one lateral wall of the ball is connected with the ball handle composed of a section of arc crank handle and a section of straight handle; a through hole is formed in the straight handle of the ball handle; the upper pore channel of the shrinkage hole in the axial pore channel is a conical pore channel; the lower pore channel is a straight pore channel; the length of the lower pore channel is greater than the length of the upper pore channel; one end of the arc crank handle is aslant and fixedly connected to the lateral wall of the ball; the axial center line of the straight handle and the center of the ball are located on the straight line; the through hole direction of the straight handle is the same as the direction of the axial pore channel of the columnar body. The pull rod spherical shell for the vehicle has the advantages of being reasonable and compact in structure, resistant to abrasion, convenient to use and install, capable of prolonging the service life and improving the use efficiency, and the like.
Description
Technical field
What the present invention relates to is a kind of automobile spherical shell of pull rod, belongs 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 object of the invention is to the deficiency overcoming prior art existence, and provide a kind of rational in infrastructure, compact, easy to install and use, its service life can be extended, improve the automobile spherical shell of pull rod of service efficiency.
The object of the invention is to have come by following technical solution, a kind of automobile 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 centre of described axial channel is provided with the shrink hole that aperture is less than duct, top and duct, bottom; One sidewall of described bulb is connected to a ball handle be made up of one section of arc crank and one section of staight shank, and the staight shank of ball handle is provided with through hole.
Duct, shrink hole top in described axial channel is tapering passage, and duct, bottom is straight hole road, and the length in duct, bottom is greater than the length in duct, top; One end of described arc crank is oblique to be fixedly connected on the sidewall of bulb, and makes the longitudinal center line of staight shank and bulb center be in always on line; Through hole direction on described staight shank is identical with the direction of column axial channel.
Described arc crank is provided be arranged symmetrically with up and down cut pin plane, and the plane that described cutting plane is oblique gradually inside export-oriented bulb; The column lateral surface of described bulb is a cydariform wall.
The present invention 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 invention.
Fig. 2 is plan structure schematic diagram of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be described in detail: shown in Fig. 1,2, a kind of automobile spherical shell of pull rod of the present invention, 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 centre of described axial channel 3 is provided with the shrink hole 4 that aperture is less than duct, top and duct, bottom; One sidewall of described bulb 1 is connected to a ball handle 2 be made up of one section of arc crank 5 and one section of staight shank 6, and the staight shank 6 of ball handle 2 is provided with through hole 7.
Shown in figure, the duct, shrink hole 4 top 8 in described axial channel 3 is tapering passage, and duct, bottom 9 is straight hole road, and the length in duct, bottom 8 is greater than the length in duct, top 9; On the oblique sidewall being fixedly connected on bulb 1 in one end of described arc crank 5, and the longitudinal center line of staight shank 6 and bulb center is made to be in always on line; Through hole direction on described staight shank 6 is identical with the direction of column axial channel 3.
Arc crank 5 of the present invention is provided be arranged symmetrically with up and down cut pin plane 10, and the plane that described cutting plane 10 is oblique gradually inside export-oriented bulb 1; The column lateral surface of described bulb 1 is a cydariform wall 11.
