Abstract
The utility model belongs to the technical field of automobile accessories and appliances and particularly relates to a pull rod spherical shell. The pull rod spherical shell comprises a spherical head and a spherical handle. The spherical head is a cylinder, wherein one side of the spherical head protrudes outwards in an arc shape. The spherical head is provided with a concave structure which penetrates through the upper end face and the lower end face of the spherical head in a communicated mode. The concave structure comprises an upper hole, a middle hole and a low hole, wherein the length of the lower hole is larger than the length of the upper hole. The spherical handle comprises a bent handle body and a straight handle body. One end of the bent handle body is fixedly connected to the lower side part of the spherical head. An arc-shaped sliding chute is formed in the position of the upper portion of the end, close to the spherical head, of the bent handle body. The other end of the bent handle body is connected with the straight handle body. The bent handle body is provided with an inward concave arc-shaped surface and an outward convex arc-shaped surface. The radian of the inward concave arc-shaped surface is 5 degrees-10 degrees. The radian of the outward convex arc-shaped surface is 2 degrees-6 degrees. The bent handle body is provided with an inward concave through hole throughout the bent handle body. The pull rod spherical shell is reasonable in structure, and service life can be prolonged.
Description
Technical field
The utility model belongs to automotive parts apparatus technical field, relates in particular to a kind of spherical shell of pull rod.
Background technology
Automobile spherical shell of pull rod 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 of pull rod and ball pin, long-time wipe contact, and poor in road conditions especially 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.Automobile also can make automobile spherical shell of pull rod stressed unreasonable with the unreasonable design of spherical shell of pull rod, and automobile occurs crackle with spherical shell of pull rod from stress raiser, and prolonged exercise can rupture.
Summary of the invention
The purpose of this utility model is to solve above-described technical matters, provides a kind of rational in infrastructure, can extend the spherical shell of pull rod of its period of service, and its technical scheme is as follows:
Spherical shell of pull rod, it is characterized in that, described spherical shell of pull rod comprises bulb and ball handle, described bulb is the cylinder that a sidepiece protrudes to outer arcuate, on bulb, offer sunk structure, sunk structure runs through two end faces up and down that are communicated with bulb, sunk structure comprises hole, mesopore and lower hole, mesopore is cylindrical hole, and upper hole is round taper hole, and from top to bottom shrink gradually in upper hole, arc transition between the upper end in upper hole and the upper surface of bulb, the lower end in upper hole is the upper end of mesopore, WeiUXing hole, lower hole, and the length in lower hole is greater than the length in hole; Described ball handle comprises crank and staight shank, one end of crank is fixedly connected in the survey bottom of bulb, the upper position place that is positioned at one end of close bulb on crank offers arc skewed slot, the other end of crank is connected with staight shank, on described crank, there are indent arcwall face and evagination arcwall face, the radian of indent arcwall face is 5-10 degree, and the radian of evagination arcwall face is 2-6 degree, and crank is provided with the indent through hole that runs through crank.
The 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 sunk structure of bulb.And sunk structure is divided into hole, mesopore and lower hole, wherein go up each difference of shape in hole, mesopore and lower hole, make ball pin can more meet mechanics principle with contacting of bulb in sunk structure, friction is between the two reduced, and be convenient to the activity of ball pin, strengthen the alerting ability of ball pin.Described ball handle comprises crank and staight shank, one end of crank is fixedly connected in the survey bottom of bulb, due to sunk structure, makes the center deviation of bulb to the bottom at bulb, make the connection of whole spherical shell of pull rod more stable so ball handle is arranged on the side lower part of bulb, be difficult for stressed fracture.Offering of arc skewed slot makes ball handle energy and bulb pulsation-free carry out transition.On crank, have indent arcwall face and evagination arcwall face, the radian of indent arcwall face is 5-10 degree, and the radian of evagination arcwall face is 2-6 degree.Indent arcwall face and evagination arcwall face be arranged so that whole spherical shell of pull rod motion process in, more meet mechanics principle, make it stressed less, extend its period of service.
