Abstract
The utility model discloses a ball pivot with inner frame, including the round pin axle of two cavity hemispherical structures, the round pin axle bilateral symmetry of two cavity hemispherical structures, the fixed round pin axle casing that becomes one and have an inside cavity of butt joint one-tenth of two cavity hemispherical structure round pin axles, the cavity intussuseption of round pin axle casing is filled with inner support frame, and the material of inner support frame is light metal. Use a ball pivot with inner frame, it supports the skeleton to pack in the cavity intussuseption of round pin axle casing, the material that supports the skeleton is light metal, not only can satisfy lightweight demand, structural strength that can also the at utmost improve the round pin axle improves the safety in utilization of product.
Description
Technical Field
The utility model relates to a metal ball round pin axle of ball pivot for automotive suspension, especially a ball round pin axle with inner frame.
Background
The thrust rod is applied to various commercial vehicles, engineering vehicles and special vehicles with balanced suspensions, is divided into an upper thrust rod and a lower thrust rod, and mainly bears the push-pull force between a balanced double axle and a vehicle frame due to traction and braking, and additional pull load, pressure load and torsional moment caused by the change of the spatial position of the axle due to steering and road surface fluctuation, so that the limit position of the axle is restrained, and the correct track of wheels is ensured when the vehicle runs. The thrust rod consists of a rod body, a rod head and a thrust rod ball hinge or a thrust rod joint which is pressed and fitted in the inner key of the rod head. The thrust rod ball hinge or joint is composed of a metal ball pin in the middle, an elastomer material wrapped outside and end covers on two sides, and generally comprises: the spherical hinge comprises a spherical hinge of a joint bearing type and a spherical hinge of a joint type wrapping rubber or polyurethane elastomers, wherein the spherical hinge is matched with a bowl-shaped joint bearing by virtue of a spherical surface of a spherical pin and is allowed to rotate freely in a certain range, and the spherical hinge of the joint bearing type is allowed to rotate by virtue of elastic deformation of the rubber or polyurethane elastomer materials. The metal ball pin in the thrust rod ball hinge or joint and the elastomer wrapped on the ball pin or the ball bowl have the strength and fatigue resistance. The traditional ball pin manufacturing method is generally forging and is of an integral solid structure, and the requirement of lighter and higher automobile weight is difficult to meet.
At present, a hollow-structure ball pin shaft is also proposed in the disclosed technical scheme and is formed by butting two hemispherical hollow-structure pin shafts, and the pin shaft with the structure can meet the light-weight requirement of a vehicle due to the fact that the hollow structure is arranged inside the pin shaft, but the overall strength is not enough, so that the pin shaft has problems in the use process, and the use safety of the vehicle is influenced.
Disclosure of Invention
The utility model aims at providing a ball round pin axle with inner frame improves round pin axle intensity under the prerequisite that can satisfy the lightweight demand.
In order to solve the technical problem, the technical scheme of the utility model as follows: the utility model provides a ball pivot with inner frame, includes the round pin axle of two cavity hemispherical structures, the round pin axle bilateral symmetry of two cavity hemispherical structures, the butt joint of two cavity hemispherical structure round pin axles becomes fixed and becomes a round pin axle casing that has inside cavity, its characterized in that: an inner support framework is filled in a cavity of the pin shaft shell, and the inner support framework is made of light metal.
The improvement of the technical scheme is as follows: the material of the inner support framework of the pin shaft shell is aluminum.
Has the advantages that:
use a ball pivot with inner frame, it supports the skeleton to pack in the cavity intussuseption of round pin axle casing, the material that supports the skeleton is light metal, not only can satisfy lightweight demand, structural strength that can also the at utmost improve the round pin axle improves the safety in utilization of product.
Drawings

In fig. 1: pin shafts 1 and 2 and an internal support framework 3.
Detailed Description
The invention is further illustrated by the following specific examples.
As shown in fig. 1 the utility model relates to a ball pivot with inner frame, including the round pin axle 1, 2 of two cavity hemispherical structures, the round pin axle 1, 2 bilateral symmetry of two cavity hemispherical structures, the butt joint of two cavity hemispherical structure round pin axles 1, 2 becomes fixed and becomes a round pin axle casing that has an inside cavity, the cavity intussuseption of round pin axle casing is filled with inner support frame 3, and the material of inner support frame 3 is aluminium.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
