Abstract
It can absorbing long-life universal joint the invention discloses one kind, it mainly include cross axle, four bearing outsides of cross axle are equipped with axle sleeve, a circle needle roller is provided between axle sleeve and bearing, vibration absorption pad is set between the needle roller and axle sleeve, it is provided with blind hole on the bearing, steel ball and spring is installed between blind via bottom and vibration absorption pad.The present invention is built between universal-joint cross trunnion blind hole and bearing using steel ball and spring and more gaskets, forms two-stage vibration absorbing structure.The axial impact energy that porous gasket can be significantly greatly increased catchment area, fully absorb cross axle to bearing, impact of the bumpered cross axis to bearing.Steel ball and spring can convert the kinetic energy of cross axle axial cyclic play to the elastic potential energy of spring, and can be changed into interior energy by the deformation of spring structure, finally dissipate away, to play the role of absorbing vibration.Reduce and damaged as cross axle universal joint caused by diameter of axle axial impact bearing, improve bearing lubrication performance, extends universal joint service life.
Description
Technical field
The present invention relates to the fields of automobile gimbal, and in particular to one kind can absorbing long-life universal joint.
Background technique
Universal joint has the function of transmitting torque and movement, is transmission shaft " joint " component.It rotates and transmits in transmission shaft
When torque and movement, the bearing of universal joint rotates in a circumferential direction around universal-joint cross trunnion axle journal, to realize that varied angle power transmits.But
When setting angle (work pivot angle) larger and revolving speed of transmission shaft is higher, universal joint bearing is not only around universal-joint cross trunnion axle journal
It rotates and axially has an opposite sliding in trunnion journal, trunnion journal end can generate bearing periodic at this time
Impact force, while a mutually sliding shearing friction power is had between trunnion journal and needle roller, vibration can be generated when serious.This
So that vibration aggravation of traditional universal joint under transmission shaft high speed, wide-angle operating condition, serious wear, the service life is short, and comfort is poor.
Existing gimbal design assumes that transmission shaft layout angle is smaller, and universal joint only does variable speed rotation, nothing with transmission shaft
Along the play of cross axle axial direction.But arrange to be more than license angle with output end when universal joint transmission shaft assembly input, especially together
When there are when high-speed cruising, the input of Cardan shaft and the variable speed type of output end obviously aggravate, abnormal vibration, cross axle
Collar end and the periodic frequent impact in axle sleeve bottom, needle roller and cross axle cause axial sliding and shear, and seriously affect ten thousand
To the service life of section.Traditional gimbal design and the design scheme for coping with such high speed wide-angle that effect is not formed, even if
There is the presence of nylon spacer structure, can slightly slow down impact vibration, but effect is not significant, therefore practical high speed, wide-angle quotient
With vehicle universal joint too early ablation phenomen frequent occurrence.
Summary of the invention
It is an object of the invention to overcome the shortcomings of the prior art, and providing one kind can absorbing long-life universal joint.
The object of the present invention is achieved by the following technical solutions: it is this can absorbing long-life universal joint, it is main to wrap
Cross axle is included, four bearing outsides of cross axle are equipped with axle sleeve, a circle needle roller is provided between axle sleeve and the axle journal of bearing, described
Vibration absorption pad is set between needle roller and axle sleeve, is provided with blind hole on the bearing, is equipped between blind via bottom and vibration absorption pad
The both ends of steel ball and spring, steel ball and spring have small ball.
Further, the vibration absorption pad is porous structure, and several apertures are equidistantly staggeredly equipped in vibration absorption pad.
Further, the natural length of the steel ball and spring is greater than the distance between blind via bottom and vibration absorption pad.
The invention has the benefit that the present invention is in the case where changing transmission shaft overall structure, by using steel ball
Helical spring and porous gasket are built between universal-joint cross trunnion blind hole (through-hole) and bearing, absorb transmission shaft high speed, big angle
Energy brought by axial impact force of the cross axle to bearing under operating condition is spent, greasy property is enhanced, reduces impact bring damage,
Improve universal joint service life.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Fig. 2 is the partial enlargement diagram of vibration absorption pad and steel ball and spring.
Description of symbols: cross axle 1, needle roller 2, vibration absorption pad 3, axle sleeve 4, bearing 5, steel ball and spring 6, blind hole 7.
Specific embodiment
Below in conjunction with attached drawing, the present invention will be described in detail:
Embodiment: as shown in the picture, it is this can absorbing long-life universal joint, mainly include cross axle 1, the four of cross axle 1
Be set with axle sleeve 4 outside a bearing 5, be provided with a circle needle roller 2 between axle sleeve 4 and the axle journal of bearing 5, the needle roller 2 and axle sleeve 4 it
Between vibration absorption pad 3 is set, be provided with blind hole 7 on the bearing 5, steel ball and spring be installed between 7 bottom of blind hole and vibration absorption pad 3
6, traditional flush end spring can be effectively prevent to destroy the extruding of gasket and cross axle blind hole, the both ends of steel ball and spring 6 have small
Its structure of steel ball can be made of materials such as steel, nylon, rubber respectively according to working condition requirement.
Preferably, the vibration absorption pad 3 is porous structure, equidistantly it is staggeredly equipped in vibration absorption pad 3 several small
Hole, the quantity and size in hole are according to specific operating condition and structure determination；In addition vibration absorption pad 3 can be manufactured using 3D printing, more
Energy conservation subtracts material.
Preferably, the natural length of the steel ball and spring 6 is greater than the distance between 7 bottom of blind hole and vibration absorption pad 3, with
This guarantees that steel ball and spring 6 has certain initial elasticity potential energy, so that compensation space changes caused length when cross axle play
Variation.
The embodiment of the present invention can be used for maintenance type and non-maintaining type universal joint simultaneously.
Present invention is mainly used for solving when transmission shaft high speed, wide-angle installation, universal joint vibration aggravation, abrasion be abnormal,
The problems such as premature wear.A kind of driving shaft universal-joint absorbing vibration suitable for high speed, wide-angle operating condition is provided.The novel universal
Save high speed, wide-angle transmission shaft when, steel ball and spring and porous gasket are installed by Bearing inner, can be by cross axle axis
It is converted into the elastic potential energy of spring and porous gasket to the kinetic energy of periodical play, and interior energy can be changed by deformation, finally
Dissipation is gone out, to play the role of absorbing vibration, is reduced because cross axle is universal caused by diameter of axle axial impact bearing
Section damage, to improve universal joint service life, and enhances comfort.
It is understood that it will be understood by those skilled in the art that being subject to technical solution of the present invention and inventive concept
It all should fall within the scope of protection of the appended claims of the present invention with replacement or change.
