Description

SPECIFICATION Bevel gear unit with positive clutch This invention relates to a bevel gear unit with a positive clutch and in particular to a unit which may be used as a locking differential.
In a known arrangement, the gear shift members on the guide sleeve are gear-shift pins, which are axially guided in bores leading into recesses at the rear of a bevel gearwheel.
This arrangement, which uses expensive gearshift members, is not really suitable for the transmission of relatively high torques and when space is restricted, for example when joints are an integral part of the cone bearings.
It is an object of the invention to provide an improved bevel gear unit which is suitable for both relatively high torques and relatively large hub diameters, while maintaining a small bevel gearwheel diameter, thereby keeping costs low and ensuring easy maintenance.
This object is in particular solved in the bevel gear unit of the present invention in that the number of gear-shift members can be increased, without reducing their diameter, by arranging them over the largest available diameter. Furthermore, no specially manufactured gear-shift members are required, In a preferred arrangement, only standardized precision balls are used. Space is also provided for a bevel gearwheel hub or collar having approximately the same diameter and whose hollow space provides room for a further universal joint, if necessary as close as possible to the bevel gearwheel, e.g. in the area below the gearshift members.
According to one embodiment of the invention, there is provided a bevel gear unit with a positive clutch in which axially guided balls, which are uniformly over the circumference of a guide sleeve which is arranged non-rotatably, connectably and coaxially with regard to a bevel side gear can engage by means of a gearshift sleeve, co-operating with the guide sleeve, in corresponding recesses in a bevel side gear, which meshes with at least one differential bevel gear arranged at a right angle to the latter, the recesses being formed in a cylindrical surface worked out of an external diameter of the bevel side gear, a cover being provided which has an internal conical surface over which the recesses are radially closed, so that, before they reach their end position on the bevel side gear side, the balls can be pushed inwards in the direction towards the centre by the gearshift sleeve when engaging in these recesses.
Conveniently, the gear casing is closed by an axial cap which is removable so that the bevel gear collar or hub can be inserted and secured as an entire unit. By using an axial securing system, which is accessible from the outside, in the guide sleeve, the entire bevel gearwheel hub can easily be taken out of the gearbox, if necessary out of a case cap, without having to completely dismantle the differential casing.
Preferably, the guide sleeve encloses a hub or collar in the bevel side gear which has a iarger internal diameter than the external diameter of the bevel side gear the external diameter of the hub corresponding to the exter nal diameter of the bevel side gear or the cylindrical surface worked onto the latter, the axial path of the balls being defined by ball guide holes formed in the guide sleeve. Thus, a particularly space saving axial securing system is achieved.
In a preferred arrangement, the hub or collar of the bevel side gear, the external diameter of which corresponds to that of the hub, is provided as a bearing block for a bearing of the bevel side gear in its recessed position under the wall of the bevel gear unit, the hub being axially secured with respect to the guide sleeve by a locking ring engaging against its inner wall, and the bearing being externally covered by a cover. In this arangement the axial securing system serves a dual purpose in that it covers the shaft bearing seal, protecting it against damage while still allowing easy assembly and maintenance.
The recesses may be formed by gaps between the teeth of the bevel side gear which has the advantage that the recesses over the circumference of the bevel gearwheel do not have to be made in a special operation, or this operation is greatly simplified.
In an alternative embodiment, the guide sleeve externally encloses the bevel gear wheels on the bevel side gear side and the gearshift sleeve, which is axially displaceable on a hub of the bevel gear unit, extends inwards below a covergent conical surface, worked internally into the end of the guide sleeve on the gearshift sleeve side, when in its inner end position, and that one hub, which is also formed as a guide sleeve of the bevel gear unit is provided over the recesses of the bevel side gear and in front on the gearshift sleeve side with further oblong ball guide holes which are provided on the gearsh ift sleeve side with a further conical surface worked externally into the guide sleeve and diverging towards the gearshift sleeve. Thus arrangement facilitates the disengagement of the balls.
In yet another embodiment, the gear-shift members consist of several shift fingers, each held at one end thereof in an internal circumferential annular groove in the gear-shift sleeve by a spherical cam, which is non-rotatably and axially and radially guided therein, said fingers each having on their other end a disc-shaped tapered thickening which is guided between guide surfaces non-rotatably and limitedly radially and axially displacable, the ends of each gear-shift member being rigidly connected by a trunk piece whose length is substantially that of the stroke of the gear-shift sleeve the outer corners of said trunk piece controlling the radial stroke of the thickening. With these gearshift members, the engagement and disengagement is simplified.
Preferred embodiments of the invention will now be described, by way of example only, with reference to the accompanying drawings, in which: Figure 1 shows one embodiment of the invention.
Figure 2 shows another embodiment and Figure 3 shows a further embodiment.
In Figure 1, a bevel gear unit 1 has a positive clutch 2, which can be actuated by a control member (not shown), in which a gearshift sleeve 3, which is axially displaceable in relation to a guide sleeve 5 is connectable with a bevel sidegear 4 by gear-shift members 6. A collar 7, extends from the bevel side gear 4. The external circumference of the bevel gear 4, which meshes with differential bevel gear 8, is approximately the same diameter as the collar 7, into which flute-type recesses 10 are machined in the axial direction in the area of the toothed wheel 9. These recesses thereby divide cylindrical surface 11, which is externally joined to the bevel gear 4, in the manner of drive teeth. In a preferred embodiment, the actual tooth gaps serve as the recesses 10.The guide sleeve 5 enclosing the collar 7 is provided in the area of the recesses 10 with ball guide holes 12, in which the gear-shift members 6, preferably formed as balls, are axially displaceable. The gear-shift balls 6 are secured in the circumferential direction by the gearshift sleeve 3 which covers them. A conical surface 13 on the interior surface of the gear shift sleeve 3 diverges in the direction of the bevel gear 4 and enables the gear-shift members 6 to engage smoothly in the recesses 10, after reaching the latter, and to be retained with an increased force.
This conical surface 13 permits a quick release from the positive engagement during the reverse movement.
The guide sleeve 5 can also be used as a bearing block for the bearing of the bevel gear 4 in the wall of the bevel gear unit 1, when the arragements is to be used as a differential gear.
Owing to the space available in the interior of the collar 7, a universal joint 15 of universal joint-shaft 16 extending from the bevel gear 4 can be readily accomodated close to the centre thereof.
By means of a locking ring 17, which can be inserted in the collar 7 and retained in position, the universal joint 15 can be axially locked in position and roller bearing 14 can be covered by a bearing cover 18 so as to be protected against dirt and damage.
The special structural composition of the bevel gear 4 and the particularly large collar 7 with corresponding by large bearings 14 externally encircling the latter, provide the additional possibility of inserting the bevel gear 4, together with the collar 7, through an end casing 19 into the gear unit 1, and withdraw-ing it from the latter again, without having to dismantle any other gear parts, such as the differential bevel gear 8 or the guide sleeve 5.
If the collar 7, which serves as a runway for the joint 15, is to be manufactured separately from the bevel gearwheel 4, it can be buttwelded at joint 20, for instance by friction welding.
In Figure 2 a guide sleeve 5.4 with oblong ball guide holes 12.1 over the area of the recesses 10 on the outer surface of the bevel gear 4, is arranged around collar 7. A further guide sleeve 5.1 externally encloses the half of the bevel gear unit 1 on the gearshift sleeve side. The balls 6 can be pressed radially from the outside by means of the sleeve 3 in the direction of the rotational axis by front conical surface 13.5 of guide sleeve 5.1 which tapers towards the bevel gear 4.In this case, the sleeve 3 is provided with circular guide holes 12.3 of smaller diameter than that of the balls 6, so that the balls 6 are guided laterally and radially in the manner of a cage, irrespect of whether they are in their internal guide sleeve 5.4, which adjoins the bevel gear 1 in the manner of a hub, or their elongate ball guide holes 12.1 are engaged in the recesses 10 in the bevel gear 4, or (as shown in the figure) they are pushed out of the recesses 10 by the sleeve 3 onto a further outwardly diverging conical surface 13.1 in the inner guide sleeve 5.4.
In the embodiment shown in Figure 3, special gear-shift fingers 6 are used instead of the balls described and illustrated in the previous embodiments, the ends of said fingers 6 having a protrusion or a spherical cam surface which engages in an inner annular groove in the gear-shift sleeve 3. The other end at the bevel gear side has a disc-shaped thickening which (like the balls of Figure 2) is guided between axial guide surfaces 13.1 and 13.5, limitedly radially and axially displacable and non-rotatable. The engagement stroke takes place as a result of the fingers 6 sliding along the guide surfaces 13.1 and 13.5 on the sleeve side. The disengagement stroke is supplemented by sliding said fingers 6 along the body of the shift fingers, provided with outer contours on the end edges, on the sleeve side, of the inner guide surfaces 13.5 Thanks to the gradually changing guide surfaces acting on both sides of the control distance, in spite of the limited space conditions, a safe, smooth and gradual switch-over is achieved in both directions.
