Abstract
The invention relates to a ball cage and joint bearing combined universal joint transmission shaft assembly which comprises a seven-channel ball cage type universal joint, a three-joint bearing type universal joint, a transmission shaft with splines at two ends, retaining rings, seal covers and hoops. A starlike inner race of the seven-channel ball cage type universal joint and a three-pin rack of the three-joint bearing type universal joint are respectively mounted on the external splines at two ends of the transmission shaft through the internal splines and axially fixed by using the elastic retaining rings, and the dust covers and the hoops are respectively arranged at the junctions of the transmission shaft and the two universal joins. The ball cage and joint bearing combined universal joint transmission shaft assembly can bear the axial displacement and the angular displacement while transferring torque, thereby not only being capable of smoothly, flexibly, reliably and precisely transferring motion and torque, but also having flexible rotation, no clamping stagnation phenomenon and high carrying capacity. The two are combined into a whole through the transmission shaft, thereby fully meeting the structural requirements of an air suspension adopted for improving the comfort and the stationarity of riding.
Description
Technical field:
The present invention relates to a kind of vehicle driving shaft assembly, more specifically to a kind of ball cage and oscillating bearing compound type universal joint transmission shaft assembly.
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: it is asynchronous that the instantaneous angular velocity of imput shaft and driven shaft can appear in cardan universal joint, thereby the biography speed and the moment of torsion of transmission are changed, the value of each moment its consequence all inequality is impact and the torsion oscillations that causes in the transmission, and along with the change of angular transposition greatly and sharply increases, when angular transposition is 30 when spending, maximum fluctuation rate can reach 15.5%.Such structure obviously is difficult to satisfy for improving the air suspension structural requirement of driving comfort, stationarity employing.
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 oscillating bearing compound type universal joint transmission shaft assembly 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 oscillating bearing compound type universal joint transmission shaft assembly comprise seven channel ball cage type universal joint, three-knuckle bearing type cardan joint, 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, the spider of described three-knuckle bearing type cardan joint is installed on the male splines of transmission shaft one end and uses 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 three-knuckle bearing type cardan joint junction 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 the three-knuckle bearing type cardan joint housing outer rim.
Described seven channel ball cage type universal joint clutch can outer rim is provided with some road sealing grooves, and cooresponding with it dust boot inner ring is provided with corresponding flange.
Described three-knuckle bearing type cardan joint housing outer rim is provided with some road sealing grooves, and cooresponding with it dust boot inner ring is provided with corresponding flange.
Compared with prior art, because the ball cage and the oscillating bearing compound type universal joint transmission shaft assembly 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.Three-knuckle bearing type cardan joint is telescopic 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, can satisfy fully for improving the air suspension structural requirement of driving comfort, stationarity employing.
Description of drawings:
Fig. 1 is the vertically positive insight structural map of one embodiment of the invention.
1. elastic scheibes among the figure, 2. seven channel ball cage type universal joint, 3. dust boot, 4. transmission shaft, 5. clip, 6. seal groove, 61. dust boot inner ring flange, 7. three-knuckle bearing type cardan joint, 8. flange grooves.
The specific embodiment:
Below in conjunction with accompanying drawing the specific embodiment is elaborated:
In one embodiment of the present of invention shown in Figure 1, a kind of ball cage and oscillating bearing compound type universal joint transmission shaft assembly, comprising seven channel ball cage type universal joint 2, three-knuckle bearing type cardan joint 7, also having two ends is transmission shaft 4, elastic scheibe 1, dust boot 3, the clip 5 of spline.The inner race of described seven channel ball cage type universal joint 2 is installed in by female splines on the male splines of transmission shaft 4 one ends and with circlip 1 axial restraint.The spider of described three-knuckle bearing type cardan joint 7 is installed in by female splines on the male splines of transmission shaft 4 one ends and with circlip 1 axial restraint.Described transmission shaft 4 is provided with dust boot 3 and clip 5 with seven channel ball cage type universal joint 2 junctions, dust boot 3 one ends are fixed in the flange groove 8 of transmission shaft by clip 5, dust boot 3 other ends are fixed on the seven channel ball cage type universal joint 2 clutch can outer rims, described seven channel ball cage type universal joint 2 clutch can outer rims are provided with some road sealing grooves 6, and cooresponding with it dust boot inner ring is provided with corresponding flange 61.Described transmission shaft and three-knuckle bearing type cardan joint 7 junctions are provided with dust boot 3 and clip 5, and dust boot 3 one ends are fixed on by clip 5 in the flange groove 8 of transmission shaft, and the dust boot other end is fixed on the three-knuckle bearing type cardan joint 7 housing outer rims.Described three-knuckle bearing type cardan joint 7 housing outer rims are provided with some road sealing grooves 6, and cooresponding with it dust boot inner ring is provided with corresponding flange 61.
The foregoing description is not construed as limiting the invention, and adopts the technical scheme that form obtained that is equal to replacement or equivalent transformation in every case, all drops within protection scope of the present invention.
