Abstract
A constant-speed universal joint is composed of drive and driven forks with different fork distances, cross axle with two unequal arms, closed cross ring and indexing mechanism between driven fork and cross axle, which is composed of indexing rod, indexing frame and ball bowl seat. So that the input and output power can be transmitted at a constant speed.
Description
A kind of cross ring type constant velocity universal joint that is used for Vehicular turn driving wheel transmission power.
Belong to the constant velocity universal transmission device in the vehicle drive system.
Retrieve foreign patent document (D.B.P.: DE2850301) Ji Zai a kind of novel constant velocity universal joint in 1980, it is a kind of ring type constant velocity universal joint of cross axle structure, its structure is that the not isometric cross axle of two arms and a sealing garden ring overlap in the same plane by hinged, its long-armed and galianconism axle and garden ring are connected with master and slave moving axis by driving and driven fork, the formation movement transferring.For realizing the constant speed transmission, this universal joint is provided with indexing mechanism.Indexing mechanism has two kinds of structural types, and a kind of is to adopt four garden bevel gears to be contained in respectively on the long and short arm of cross axle, utilizes the working principle of differential mechanism to carry out the transmission of calibration realization constant speed.This complex structure, cost height, lubricated, sealing difficulty.Another kind is to adopt the slide block that has axle sleeve, axle sleeve is enclosed within on cross axle long-armed, and the slide block basal plane matches with fixed pan the garden ring position is carried out calibration, though its structure is simple, but only be applicable to that driving and driven axle clamp angle is changeless situation, therefore can not be used for the motor turning driving wheel.
For overcoming above-mentioned defective, the utility model provides a kind of cross ring type constant velocity universal joint with the Lever type indexing mechanism.
Searching document is described as described above for this cross ring type constant velocity universal joint structure, but the indexing mechanism on it is provided in a side of between driven fork and the cross axle, and by index lever, calibration frame and ball bowl seat are formed.It is characterized in that index lever one end is contained in driven sticking, the other end is packed into by calibration frame, cross axle in the ball bowl seat, ball bowl seat then is connected on the driving shaft, calibration as the lever motion transmitting element is erected on the cross axle, the long-armed axle that makes index lever can drive cross axle with the rotation of driven fork rotates, the long-armed axle of cross axle is on the angle bisector plane of master and slave moving axis all the time, and the power transmission point that is about to master and slave moving axis acts on this bisector plane, thereby realizes the power transmission of congruence speed.
This partition ring constant velocity universal joint is simple in structure, with low cost, and lubrication and seal is good, reliable operation, and constant speed transmission power effect is good, is suitable for being contained on the f-w-d car of independent suspension.
The embodiment of concrete structure of the present utility model will describe in detail in conjunction with the following drawings.
Fig. 1, the plan view of cross ring type constant velocity universal joint.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the sectional view of Fig. 1.
Fig. 4, cross ring type constant velocity universal joint indexing mechanism schematic diagram.
Fig. 5, cross ring type constant velocity universal joint constant speed transmission principle figure.
Fig. 6, the cross ring type constant velocity universal joint plan view of band boss calibration frame.
Fig. 7 is the sectional view of Fig. 6.
Fig. 8 is the sectional view of Fig. 7.
As seen from the figure, the cross ring type constant velocity universal joint of this structure, initiatively pitch 1 by fork apart from what do not wait, driven fork 2, the cross axle 3 that two arms are not isometric, the partition ring 4 and the indexing mechanism of sealing are formed, partition ring 4 is provided with two pin-and-holes and two bearing pins that its axis is orthogonal and the position is symmetrical, cross axle 3 its long-armed axles are hinged in two pin-and-holes of partition ring 4, its galianconism is with initiatively to pitch 1 hinged, two bearing pins of partition ring 4 are then hinged with driven fork 2, described indexing mechanism is located between driven fork 2 and the cross axle 3, by index lever 7, calibration frame 6, ball bowl seat 5, spring 8 is formed, the root of driven fork 2 vertically center line have a blind hole, be provided with spring 8 in the blind hole, the center of cross axle 3 has a through hole, the through hole that ball bowl seat 5 passes cross axle 3 is connected on the driving shaft, described index lever 7 is equipped with the bar of ball pin for two ends and middle part, wherein an end ball pin is packed in the blind hole of moving fork 2, the other end is by calibration frame 6, cross axle 3 is contained in the ball bowl seat 5, calibration frame 6 has two kinds of structures, a kind of is the calibration frame 6 that the middle part is provided with through hole, and the two ends of this calibration frame 6 are hinged on the long-armed axle of cross axle 3.Through hole on it matches with the middle part ball pin of index lever 7.Another kind of calibration is erected at cross axle 3 center portions.Its structure is to match with index lever 7 middle part ball pins by ball bowl 12 between the symmetrical boss, two boss of two parallel cross axle 3 galianconism axis.Each hinged place of said structure is equipped with needle bearing 9.10.11.
Claims (2)
