Abstract
The invention discloses a kind of spring shock and vibration absorption type novel long-life universal joints, 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 the axle journal of bearing, gasket 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 gasket, the both ends of steel ball and spring have small ball.When the present invention solves transmission shaft high speed, wide-angle installation, the service life is short, comfort is poor problem.When the Universal joint is used in the transmission shaft of high speed, wide-angle, the helical spring of Bearing inner can convert the kinetic energy of cross axle axial cyclic play to the elastic potential energy of spring, and interior energy can be changed by the deformation of spring structure, finally dissipate away, to play the role of absorbing vibration, reduce because cross axle universal joint caused by diameter of axle axial impact bearing damages, to improve universal joint service life, and enhances comfort.
Description
Technical field
The present invention relates to the fields of automobile gimbal, and in particular to a kind of spring shock and vibration absorption type novel 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 provide a kind of spring shock and vibration absorption type novel long-life
Universal joint.
The object of the present invention is achieved by the following technical solutions: this spring shock and vibration absorption type novel long-life is universal
Section, mainly includes cross axle, and four bearing outsides of cross axle are equipped with axle sleeve, a circle is provided between axle sleeve and the axle journal of bearing
Needle roller is arranged gasket, is provided with blind hole on the bearing, is equipped between blind via bottom and gasket between the needle roller and axle sleeve
The both ends of steel ball and spring, steel ball and spring have small ball.
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 being built in universal-joint cross trunnion blind hole (through-hole) and bearing shim using steel ball and spring
Between, cross axle is absorbed to the axial impact energy of bearing, and impact of the bumpered cross axis to bearing reduces cross axle to greatest extent
Impact the damage to bearing.Meanwhile the flexible grease mobility that can enhance in cross axle oilhole of periodicity of spring, improve bearing
Greasy property, to improve the service life and vehicle comfort of universal joint.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Fig. 2 is the partial enlargement diagram of steel ball and spring.
Description of symbols: cross axle 1, needle roller 2, gasket 3, axle sleeve 4, bearing 5, 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, this spring shock and vibration absorption type novel long-life universal joint mainly includes cross axle 1, cross
Axle sleeve 4 is set with outside four bearings 5 of axis 1, is provided with a circle needle roller 2 between axle sleeve 4 and the axle journal of bearing 5, the needle roller 2 with
Gasket 3 is set between axle sleeve 4, is provided with blind hole 7 on the bearing 5, steel ball and spring is installed between 7 bottom of blind hole and gasket 3
6, the both ends of steel ball and spring 6 have small ball its structure can be according to working condition requirement, respectively by materials such as steel, nylon, rubber
It is made, traditional flush end spring can be effectively prevent to destroy the extruding of gasket 3 and cross axle blind hole 7.
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.
The present invention is built in universal joint cross in the case where not changing transmission shaft overall structure, by using steel ball and spring
Between axis blind hole (through-hole) and bearing shim, axial impact of the cross axle to bearing under absorption transmission shaft high speed, wide-angle operating condition
Energy brought by power reduces impact bring damage, improves universal joint service life.
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.
