Definitions
- the invention relates to a universal joint with two opposing forks which are offset by 90 ° from one another, each of which is part of one of two articulated shafts, or which can each be connected to one of two articulated shaft ends, and two offset by 90 ° to each other and forming a loose spigot pairs, which are mounted on the respective fork ends, the two pairs of pins in the plane formed by the spigot are pivotable against each other by a predetermined angle, with at least one pivot pin with its two outer connecting pins in each an elastic elastomer bushing is mounted, and at least these two elastomer bushings are connected to one another via a rigid circumferential ring, and wherein the rigid circumferential ring in the direction of the axis of the pivot pin contains radial recesses for at least two elastomer bushings, which are for receiving e the connecting pin together with the elastomer bushings are suitable, and the rigid circumferential ring is designed in such a way that it runs in
- Universal joints form torque-transmitting connections of shafts, the axes of rotation of which do not always or temporarily align with one another during operation, but instead have a flexion angle.
- elastic universal joints have been developed to avoid vibration transmission, particularly in motor vehicle construction. Elastic deformable elements in the
- the universal joint reduces the transmission of axial vibrations and torque vibrations through the universal joint.
- Elastic universal joints are therefore preferably used in the drive train and in the steering train of motor vehicles.
- the two pairs of joint pins aligned with one another, of which one pair of joint pins is connected to one fork and the other pair of joint pins to the other fork of the universal joint, are made by elastic components decoupled from one another in such a way that, although torque transmission takes place, vibration transmission in the axial direction and in the circumferential direction [is reduced.
- the common circumferential ring connecting all the radially projecting connecting pins is designed to be elastic. Loop-shaped reinforcement inserts made of high-strength cord thread are embedded in the elastic circumferential ring. Connect two adjacent connecting pins in the circumferential direction.
- the object of the invention is therefore to design a universal joint of the type mentioned in such a way that an effective and reliable torque transmission between the two shafts or shaft ends is possible with a high, largely freely controllable vibration damping effect, in particular also with regard to torque vibrations.
- This task is solved according to the invention in that the fork ends are rotatably mounted on the articulated pins forming the cross-piece in rigid pin bearings. Only by designing the journal bearings as rigid, d. H. not substantially elastically deformable pivot bearing ensures that a torsion rate is built up between the drive shaft and the output shaft in the required dimensions and thus a torque is transmitted.
- elastomer bushings as elastic, vibration-damping elements in a universal joint has the Advantage that the vibration damping effect to be achieved can be freely influenced over a wide range by the choice of the dimensions and the material of the elastomer bushings, but a reliable emergency running property of the universal joint is retained even if the elastomer parts are destroyed.
- the radially projecting connecting pins of the joint pins then still engage in a form-fitting manner - albeit with a certain amount of play - in the receiving bores of the rigid circumferential ring, so that even in this extreme case a high torque transmission is ensured.
- the use of elastomer bushings also allows targeted control of the vibration-damping properties, specifically even in the axial and circumferential directions.
- Gungsdampfungs Bark m many cases additional vibration-damping elements must While in prior art universal joints because of insufficient usually Schw be provided adjacent to the universal joint, ⁇ o twist the axial space requirement increases, the arbitrarily customizable Schwmgungsdampfung causes no additional space in the inventive shaped universal joint, either the axial direction or in terms of diameter, because the rigid circumferential ring which receives the elastomer bushings has essentially the same space requirement as the elastic circumferential bead of the known elastic universal joint.
- journal bearings are preferably designed as roller bearings, in particular as needle bearings.
- each connecting pin is non-rotatably connected to an inner sleeve of the elastomer bushing.
- the elastomer bushing preferably has at its fork-side end an elastic circumferential flange, for example an O-Rmg, which forms a sealing ring between the receiving bore in the circumferential ring and the adjacent fork end.
- a seal of the journal bearing of the joint journal which is preferably designed as a needle bearing with a permanent lubrication filling, is thus sealed off from the outside, so that loss of lubricant and the penetration of contaminants are avoided.
- edge flanges of the elastomer bushings are advantageously arranged with a prestress acting in the longitudinal direction of the pin between the circumferential ring and the respectively adjacent fork end. This preload in the direction of the center of the joint reduces play.
- the pre-tensioning force can be chosen larger than the force resulting from the respective bending moment.
- FIG. 3 an axial section corresponding to FIG. 1
- the universal joint shown in FIGS. 1 and 2 which is used, for example, in the auxiliary line or in the steering line of a motor vehicle, has two opposing forks 1, 2 which are connected to the torque-transmitting shaft ends (not shown) to be connected.
- the fork ends 1 a and 2 a of the forks 1, 2, offset by 90 m circumferential direction, are connected to one another in an articulated manner by an axially and m circumferentially movable cross member 3.
- the split spigot 3 has two pairs of two pivot pins 4 and 5, respectively, which are aligned with one another.
- the two pivot pins 4, 5 of the first pair are rigidly connected to one another via a pin web 6 and are each rotatably mounted in the two fork ends 1 a of the fork 1 via a pin bearing 7 designed as a needle bearing.
- the two aligned pivot pins 4a and 5a of the second pair which run at right angles to the pivot pins 4,5, are also rigidly connected to one another via a pin web 8 and are rotatably mounted on the fork ends 2a of the fork 2 via pin bearings 9m designed as needle bearings.
- a connecting pin 10 which carries an elastomer bushing 11, adjoins one another radially outward.
- the connecting pin 10 provided on its outer surface with long profiles is non-rotatably pressed into an inner ring 12 of the elastomer bushing 11 and axially positioned with a securing element 13.
- Each elastomer bushing 11 protrudes a radial receiving bore 14 of a rigid circumferential rim 15, which thus connects all four connecting pins 10 and thus also all articulated pins 4,5 and 4a, 5a of the entire movable cross member 3 via an elastomer bushing 11.
- Each elastomer bushing 11 has at its fork-side end an elastic edge flange 16 which projects into the gap between the end of the receiving bore 14 and the outer surface of the respectively adjacent fork end la or 2a.
- the elastic edge flange 16 there forms a sealing ring between the receiving bore 14 and the fork end la or 2a, which seals the journal bearing 7 to the outside at the top.
- the edge flanges 16 of the elastomer bushings 11 are arranged with a prestress acting in the longitudinal direction of the journal between the circumferential ring 15 and the respectively adjacent fork end la or 2a. This eliminates any play in the longitudinal direction of the pin and maintains a pretensioning craft which is higher than the possible force resulting from the bending moment during the operation of the universal joint.
- Each pivot pin 4, 5 or 4a, 5a has, adjacent to each pin bearing 7, a support flange 7a that can be axially supported on the pin bearing 7. As a result, all parts of the universal joint are kept aligned with one another in the radial direction in such a way that there is an unchangeable moment center in the center of the joint.
- Fig. 3 shows the use of the elastic universal joint described in a double universal joint.
- One fork 1 of the elastic universal joint here forms part of a central housing 17, which is in the opposite direction to m elastic universal joint carries another, non-elastic, ie rigid universal joint 18.
- the non-elastic universal joint 18 has a rigid journal cross 19, the joint journals 20 of which are mounted in pairs in a fork 21 of the central housing 17 and a fork 22.
- the fork 22 is provided at its end facing the elastic universal joint with a spherical bearing 23 made of elastic dam material.
- Gut is a ball 24 freely rotatably and pivotally embedded, which is connected to the fork 2 of the elastic universal joint.
- rotation also takes place in the area of the ball joint 23, 24.
- the ball joint 23, 24 effects an angle synchronization of the two interconnected universal joints. Elastic decoupling in the axial direction and in the circumferential direction is also ensured in the case of the elastic double universal joint according to FIG. 3 by the elastomer bushings 11.
- the elastomer bushings 11 can - as shown in the drawing - be cylindrical. Instead of this, oval or square-shaped elastomer bushings made of elastically flexible elastomer are also possible in order to achieve different damping properties in the circumferential direction and in the axial direction. It is also possible to provide elongated, kidney-shaped or m-shaped recesses m of the elastomer bushing 11 in order to make the suspension effect different in different directions.
