Abstract
The invention relates to a ball cage and four-ball-pin combined type universal joint transmission shaft assembly which comprises a seven-channel ball cage type universal joint, a four-ball-pin type constant velocity universal joint, a transmission shaft of which both ends are provided with splines, ring washers, sealing covers and hoops, wherein a star-shaped sleeve of the seven-channel ball cage type universal joint and four pin frames of the four-ball-pin type constant velocity universal joint are respectively arranged on the outer splines at two ends of the transmission shaft through the inner splines and axially fixed by using the elastic ring washers; and the connecting parts of the transmission shaft and the universal joint are respectively provided with the dust cover and the hoop. The ball cage and four-ball-pin combined type universal joint transmission shaft assembly can bear axial displacement and angular displacement while transmitting a torque, and not only can steadily, flexibly, reliably and precisely transmit motions and the torque, but also has the advantages of flexible rotation, no clamping stagnation phenomenon and high bearing capacity. In the invention, the four-ball-pin combined type universal joint and the seven-channel ball cage type universal joint are combined together through the transmission shaft, wherein the four-ball-pin combined type universal joint is arranged at the side close to a transmission, and the seven-channel ball cage type universal joint is arranged at the side of a drive axle, which can completely meet the structural requirement on a vehicle air suspension structure.
Description
Technical field:
The present invention relates to a kind of vehicle driving shaft assembly, more specifically to a kind of ball cage and four ball pin compound type universal joint transmission shaft assemblies.
Background technology:
Propeller-shaft is the vitals that connects in the car transmissions between change-speed box and the drive axle, in the prior art, transmission shaft adopts double flange V shape propeller-shaft mostly, promptly guarantees transmission shaft transfer torque and length, angle variable quantity by former and later two cardan universal joints and free-sliding spline pair.This structure shows that with use following weak point is arranged by analysis: first cardan universal joint transfer torque is little, transmission efficiency is low, limit speed is low; Two to be that the instantaneous angular velocity of imput shaft and driven shaft can appear in cardan universal joint asynchronous for it, thereby the biography speed and the moment of torsion of transmission are changed; It three is that leak tightness is poor, and the free-sliding spline pair is easy to wear.In recent years along with air suspension applying on automobile is more and more, for having improved traveling comfort and the stationarity of taking, have higher requirement for the driving system between change-speed box and the drive axle, seeking to satisfy driving and driven between centers longitudinal travel driving-shaft assembly big, that angular transposition is big and transmitting torque is big is a problem that urgency is to be studied.
Summary of the invention:
The objective of the invention is to provide at the prior art weak point a kind of simple in structure, load-carrying capacity is high, can satisfy the existing longitudinal travel of master and slave moving axis transmits the ball cage and the four ball pin compound type universal joint transmission shaft assemblies of moving fortune and torque when angular transposition is arranged.
The objective of the invention is to realize by following measure: a kind of ball cage and four ball pin compound type universal joint transmission shaft assemblies comprise seven channel ball cage type universal joint, four ball-and-spigot constant-velocity universal joints, it is characterized in that: also having two ends is transmission shaft, ring washer, seal closure, the clip of spline; The inner race of described seven channel ball cage type universal joint is installed on the male splines of transmission shaft one end and uses the circlip axial restraint by female splines, four pin framves of described four ball-and-spigot constant-velocity universal joints are installed on the male splines of transmission shaft one end and use the circlip axial restraint by female splines, described transmission shaft and seven channel ball cage type universal joint junction are provided with dust boot and clip, dust boot one end is fixed in the flange groove of transmission shaft by clip, the dust boot other end is fixed on the seven channel ball cage type universal joint clutch can outer rim, described transmission shaft and four ball-and-spigot constant-velocity universal joint junctions are provided with dust boot and clip, dust boot one end is fixed on by clip in the flange groove of transmission shaft, and the dust boot other end is fixed on four ball-and-spigot constant-velocity universal joints, the four post pot shell outer rims.
Described seven channel ball cage type universal joint clutch can outer rim is provided with seal groove, and cooresponding with it dust boot inner ring is provided with corresponding flange.
Described four ball-and-spigot constant-velocity universal joints, four post pot shell outer rims are provided with seal groove, and cooresponding with it dust boot inner ring is provided with corresponding flange.
Compared with prior art, because the ball cage and the four ball pin compound type universal joint transmission shaft assemblies that have adopted the present invention to propose, seven channel ball cage type universal joint is a fixed type constant velocity cardan joint, its power transmission point is positioned on the bisector of diaxon intersection point forever, make each instantaneous angular velocity ratio of diaxon be constant, and the seven channel ball cage type transfer torque is maximum in the like product.Four ball-and-spigot constant-velocity universal joints are telescopic constant-velocity universal joint, can bear longitudinal travel and angular transposition simultaneously, steadily, flexibly, reliably and accurately transmitting movement and torque, and also revolution is flexible, no catching phenomenon, the load-carrying capacity height.By transmission shaft both are combined as a whole, four ball pin compound type universal-joints are installed in by change-speed box one side, seven channel ball cage type universal joint is installed in and drives sedan-chair one side, can satisfy fully for improving the air suspension structural requirement of driving comfort, stationarity employing.
