Abstract
The utility model discloses a shaft joint connected by an elastic cushion, comprising a driving hitch yoke, a driven hitch yoke and a connection gasket. The two hitch yokes are respectively provided with jaws, and the circumference direction of the connection gasket is evenly provided with jaws which are matched with the jaws on the two hitch yokes. The utility model has the advantages of convenient assembly and low noise.
Description
Technical field
The utility model belongs to mechanical coupling structure field, is specifically related to motor shaft in the automobile electric booster steering system and the linkage structure between the coupled axle.
Background technique
Mechanical coupling is of a great variety, be widely used, with a long history.Constantly improve along with the variation of engineering structure and development with to the requirement of coupling, the coupling of making of new material, new structure is also occurring successively.
Between the motor shaft and worm shaft of automobile electric power-assisted steering, once extensively used splined, promptly external splines is made on the worm shaft, and internal spline is made on the motor shaft.Though the size of itself is little, in light weight, simple in structure, cost is also low, also have radial missing and the exigent shortcoming of axial deviation that machining is produced; Be difficult to eliminate the backlash that produces because of machining or because of service wear; Can also bring a series of shortcomings such as operational noise behind the flank generation gap.
Summary of the invention
At the above defective that exists in the prior art, it is a kind of easy to assembly that the utility model provides, the coupling that the cushion that noise is low connects.
The technical solution adopted in the utility model is as follows: the coupling that a kind of cushion connects comprises initiatively clevis, driven clevis and connection pad; Be respectively equipped with the tooth embedding on two cleviss, corresponding connection pad circumferentially evenly is provided with the tooth embedding that matches with tooth embedding on two cleviss.
The coupling that cushion of the present utility model connects, connection pad is made of rubber material.
It is identical that the coupling that cushion of the present utility model connects, the tooth embedding number on the connection pad and the tooth embedding on two cleviss are counted sum.
The coupling that cushion of the present utility model connects, the structure of two cleviss and measure-alike, both can exchange.
The coupling that cushion of the present utility model connects, clevis is a separate piece, through compression fit to axle.
The utlity model has following advantage:
(1), install and use the utility model elastic coupling flexible coupling, so the deviation and the mounting point deviation effects that are not subjected to machining during assembling and are produced are easy to assembly.
(2), install and use the utility model elastic coupling flexible coupling, can eliminate the gap that produces because of machining or because of service wear.
(3), install and use the utility model elastic coupling flexible coupling, can eliminate vibration and operational noise, this is to reducing noise, it is necessary to improve travelling comfort.
Description of drawings
Fig. 1 is the utility model embodiment's a structural representation;
Fig. 2 is the utility model embodiment's a part assembly drawing.
Embodiment:
As shown in the figure, the utility model elastic coupling flexible coupling comprises motor shaft 1, active clevis 2, connection pad 3, driven clevis 4 and driven shaft 5.Two cleviss are general.End mill at clevis has the tooth embedding.Connection pad 3 usefulness rubber are manufactured.Connection pad 3 is along circumferentially being evenly divided into several tooth embeddings, and it is identical that sum is counted in quantity and the tooth embedding on two cleviss.On the one hand initiatively clevis 2, driven clevis 4 are to be installed on motor shaft 1 and the driven shaft 5 by their endoporus, are interference fit between the two.Initiatively clevis 2, driven clevis 4 are interconnected by their end tooth embeddings and connection pad 3 again on the other hand, require the size of tooth embedding can satisfy assembling after realization between the two compress mutually.Present embodiment initiatively clevis 2, driven clevis 4 upper tooth embedding numbers is each two, and connection pad 3 upper tooth embedding numbers are four.
The present embodiment working procedure is as follows with principle: when the utility model elastic coupling flexible coupling is connected motor shaft 1 and driven shaft 5, be to realize by the connection pad made from rubber 3, therefore can eliminate the deviation that is produced when installing and making by its elastic reaction.This is favourable to installing.
In the time of machine operation, output power by motor shaft.Because of active clevis 2 is an interference fit with motor shaft,, and then pass to driven shaft 5 so power can pass to connection pad 3 and driven clevis 4 through active clevis 2.Because connection pad is a rubber parts, and be again around here, so can not produce noise and vibration transferring power the time by tooth embedding on it and the mutual compression fit of tooth embedding on the clevis.
Claims (5)
1, a kind of coupling of cushion connection is characterized in that: comprise initiatively clevis, driven clevis and connection pad; Be respectively equipped with the tooth embedding on two cleviss, corresponding connection pad circumferentially evenly is provided with the tooth embedding that matches with tooth embedding on two cleviss.
