Abstract
The invention discloses a kind of long-life universal joint with vibration absorption pad, 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, vibration absorption pad is set between the needle roller and axle sleeve, the vibration absorption pad is porous structure, and several apertures are equidistantly staggeredly equipped in vibration absorption pad.The present invention is not in the case where changing transmission shaft overall structure, by the structure for improving universal joint middle (center) bearing gasket, bearing shim is designed as porous structure, increase gasket oil storage capacity, bearing shim is set to play the role of a buffer spring simultaneously, energy brought by axial impact force of the cross axle to bearing under transmission shaft high speed, wide-angle operating condition can be absorbed, impact bring damage is reduced, improves universal joint service life.
Description
Technical field
The present invention relates to the fields of automobile gimbal, and in particular to a kind of long-life universal joint with vibration absorption pad.
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 universal-joint journal end and bearing bottom oil storage and bumpered cross axis and bearing bottom in the form of entity gasket
The impact vibration in portion, this design scheme are extremely limited the oil storage capacity of gasket and damping effect, be not enough to improve high speed,
Universal joint service life under wide-angle operating condition.
Summary of the invention
It is an object of the invention to overcome the shortcomings of the prior art, and provide a kind of long-life with vibration absorption pad
Universal joint.
The object of the present invention is achieved by the following technical solutions: this long-life with vibration absorption pad 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
Vibration absorption pad is arranged in needle roller between the needle roller and axle sleeve, the vibration absorption pad is porous structure, equidistant in vibration absorption pad
It is staggeredly equipped with several apertures.
The invention has the benefit that the setting of porous gasket can be significantly greatly increased catchment area, fully absorb cross axle
To the axial impact energy of bearing, impact of the bumpered cross axis to bearing reduces cross axle impact to the damage of bearing to greatest extent
Wound improves bearing lubrication performance, 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 vibration absorption pad.
Description of symbols: cross axle 1, needle roller 2, vibration absorption pad 3, axle sleeve 4, bearing 5.
Specific embodiment
Below in conjunction with attached drawing, the present invention will be described in detail:
Embodiment: as shown in the picture, this long-life universal joint with vibration absorption pad 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
Vibration absorption pad 3 is set between axle sleeve 4, and the vibration absorption pad 3 is porous structure, is equidistantly staggeredly equipped in vibration absorption pad 3
Several apertures, for the quantity and size in hole according to specific operating condition and structure determination, cross axle pair is can be absorbed in the gasket of porous structure
The impact energy of bearing, plays buffer function, in addition, vibration absorption pad 3 can be manufactured using 3D printing, it is more energy saving to subtract material.
The present invention is not in the case where changing transmission shaft overall structure, by improving the structure of universal joint middle (center) bearing gasket,
Bearing shim is designed as porous structure, increases gasket oil storage capacity, while bearing shim being made to play the work of a buffer spring
With can absorb transmission shaft high speed, energy brought by axial impact force of the cross axle to bearing under wide-angle operating condition, reduce punching
Bring damage is hit, universal joint service life is improved.
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.
