Abstract
The utility model discloses universal-joint fork, including jaw sleeve, the central authorities of jaw sleeve are provided with cross axle trepanning, the outboard end of jaw sleeve is provided with lower fork ear, the outboard end end face of upper lower fork ear is provided with power transmission shaft connecting hole and central authorities' slot, it is characterized in that: the left-hand end of upper lower fork ear is connected by circular arc floor, and circular arc floor is arranged near the inner edge of upper lower fork ear；The both sides cell wall of described central authorities slot is provided with woodruff key bodies, corresponding with the semi circular surface of woodruff key bodies, and the both sides cell wall of central authorities' slot is provided with inner concave arc surface, and the height of woodruff key bodies is more than the height of inner concave arc surface.This utility model structural strength is high, circumferentially positioned accurately, service life is long.
Description
Technical field
This utility model relates to a kind of vehicle transmission part, is specifically related to a kind of automobile gimbal fork.
Background technology
The structure of tradition universal-joint fork is: including that jaw sleeve, the central authorities of jaw sleeve are provided with cross axle trepanning, the outboard end of jaw sleeve is provided with lower fork ear, and the outboard end end face of upper lower fork ear is provided with power transmission shaft connecting hole and central authorities' slot.The maximum deficiency that tradition universal-joint fork exists is: structural strength is the highest, and service life is the longest, and when being connected with power transmission shaft, circumference can not be accurately positioned.
Summary of the invention
The problem existed in view of currently known technology, the purpose of this utility model is intended to provide a kind of structural strength high, circumferentially positioned accurately, service life length universal-joint fork.
This utility model has adopted the following technical scheme that:
Universal-joint fork, including jaw sleeve, the central authorities of jaw sleeve are provided with cross axle trepanning, the outboard end of jaw sleeve is provided with lower fork ear, the outboard end end face of upper lower fork ear is provided with power transmission shaft connecting hole and central authorities' slot, it is characterized in that: the left-hand end of upper lower fork ear is connected by circular arc floor, and circular arc floor is arranged near the inner edge of upper lower fork ear.
In technique scheme, connected by circular arc floor between upper lower fork ear, thus be effectively increased the structural strength of lower fork ear, improve service life.
As preferably, the both sides cell wall of described central authorities slot is provided with woodruff key bodies, corresponding with the semi circular surface of woodruff key bodies, and the both sides cell wall of central authorities' slot is provided with inner concave arc surface, and the height of woodruff key bodies is more than the height of inner concave arc surface.By the setting of woodruff key bodies, when universal-joint fork can be enable to be connected with power transmission shaft, circumference is quickly accurately positioned, thus improves accuracy and the convenience of assembling.
As preferably, jaw sleeve, circular arc floor and upper lower fork ear are integrated forging molding.
Accompanying drawing explanation
This utility model has a drawings described below:
Fig. 1 is structural representation of the present utility model,
Fig. 2 is the A-A view of Fig. 1.
