Abstract
The coupling comprises a first coupling member 23, a second coupling member 31 and latching means 29,30 to axially lock said first and second coupling members together against axial separation, engagement of said latching means being effected by axial movement of the two coupling members into interengagement and by subsequent rotation of one coupling member relative to the other coupling member in one direction. The coupling members are unlockable for axial separation by further relative rotation of one coupling member relative to the other only in said one direction to disengage the latching means. The coupling is used to connect a clutch release member 17 of a clutch assembly. The coupling may also be assembled by axially aligning the respective latching means, and moving the two members axially relatively to each other, disassembly again being effected by relative rotation of the members. <IMAGE>
Description
SPECIFICATION
A disengageable coupling and a clutch release mechanism incorporating same
This invention relates to disengageable couplings suitable for transmitting rectinlinear forces between two parts of a mechanism that need to be disengaged to allow the mechanism to be serviced or replacement parts fitted.
Such a mechanism is clutch release mechanism for a pull type clutch, where it is a requirement for the release mechanism to be disengaged from the clutch to allow the transmission and engine to be separated.
It is usual for the clutch to be housed in a housing member joining the transmission to part of the engine, and accessibility is therefore limited. It is known to provide a disengageable coupling in which both engagement and disengagement of the coupling can be accomplished automatically by operation of the release mechanism in a certain manner. These couplings are however normally complicated in construction and therefore expensive to manufacture.
It is an object of this invention to provide a disengageable coupling that is simple in construction.
According to an aspect of the invention there is provided a disengageable coupling comprising a first coupling member, a second coupling member and latching means to axially lock said first and second coupling members together against axial separation, engagement of said latching means being effected by relative axial movement between the two coupling members into interengagement and by subsequent rotation of one coupling member relative to the other coupling member in one direction, the coupling members being unlockable for axial separation by further relative rotation of one coupling member relative to the other in said one direction to disengage the latching means.
According to another aspect of the invention there is also provided a disengageable coupling member comprising a first coupling member, a second coupling member and latching means to axially lock said first and second members together against axial separation, the latching means comprising complementary latching surfaces on the first and second coupling members, engagement of the latching means being effected by the angular alignment of said latching surfaces and the subsequent relative axial movement between the two coupling members into interengagement, the coupling members being unlockable for axial separation by relative rotation of one coupling member relative to the other in one direction.
The invention also includes a clutch release mechanism having a clutch release member for connection, e.g. to a clutch pedal linkage, and a disengageable coupling according to either of the two immediately preceding paragraphs.
Preferably the coupling members are unlockable for axial separation by further relative rotation of one coupling member relative to the other only in said one direction to disengage the latching means.
The latching means may comprise latching surfaces on the first and second coupling members.
The latching surfaces may be biased into engagement resiliently. The resilient bias may be provided by a resilient portion of one of the first and second members, e.g. a cantilever spring formed integrally with said one member.
The latching means may comprise at least one projection on one of the first and second of said coupling members for co-operation with a respective aperture or recess in the other of the first and second coupling members. The latching surfaces may comprise a radially extending surface on one side of each projection and a respective radially extending surface in each aperture or recess.
Each projection may have a ramp portion on an adjacent side of the radially extending surface, which ramp portion may be inclined in the axial direction of the coupling.
Each projection may have a ramp portion on each of two adjacent sides one of which may be inclined in the circumferential direction.
Preferably the clutch release member includes a release bearing having non-rotatable and rotatable parts one part of which is connected to said disengageable coupling. The said one part may be formed integral with one of said first and second coupling members.
Preferably locking means are provided to prevent rotation of said rotatable part relative to said non-rotatable part in at least one direction when the clutch release member is moved beyond its normal rest position in a direction opposite to that used for normal operation of the clutch release mechanism. The locking means may comprise at least one axially projecting member on the release member or the rotating part for engagement with a respective aperture or recess on the other of the release member or rotating part. Alternatively, the locking means may comprise at least one lug on the second coupling member for co-operation with a lever forming part of a clutch pedal linkage.

XVII-XVII in Fig. 16. With reference to Figs.
1 to 10 there is shown a disengageable coupling comprising a first coupling member 23, a second coupling member 31 and latching means 29, 30 to axially lock the first and second coupling members 23, 31 together against axial separation.
The first coupling member 23 comprises an annular end portion 40 having two parallel arms 41 extending away from it in the same direction.
Each of the arms 41 forms a cantilever spring that can be resiliently deflected upon assembly by the second coupling member 31 to provide a biassing force therebetween.
The arms 41 each have a step 43 towards a chamfered end 42 away from the annular end portion 40, and an aperture 29 extending from a position near to the annular end portion 40 to a position near to the chamfered end 42. Each of the apertures 29 having two side walls 57 and two end faces 56 one of which forms a radially extending latching surface.
The second coupling member 31 is substantially tubular and has two diametrically opposed inwardly extending projections 30 near an end face 45. Each of the projections 30 has a first ramp portion 53 facing towards the end face 45, a first shoulder portion 55 forming a radially extending latching surface facing away from the end face 45, a second ramp portion 50 on an adjacent side to both the first ramp portion 53 and the first shoulder portion 55 and a second shoulder portion 52 on an opposite side from the second ramp portion therebeing four sides in all. The ramp portion 53 is inclined in the axial direction of the coupling member 31 and the ramp portion 50 is inclined in the circumferential direction.
Engagement of said latching means 29, 30 is effected by axial movement of the two coupling members 23, 31 into interengagement and by the subsequent rotation of one coupling member 23 or 31 relative to the other coupling member 31 or 23 in one direction.
Initially the relative rotation brings an edge of each of the arms 41 into contact with the ramp portion 50 of the respective projection 30 with which it co-operates (as shown in
Fig. 8). Further relative rotation causing arms 41 to be deflected as they ride up the respective ramp portions 50 of the projections 30 (as shown by position D-D in Fig. 9), the arms 41 are not permanently deformed by the deflection due to interaction with the projections 30 as they act as cantilever springs biassing the apertures 29 outwardly for engagement with the projections 30.
When each of the projections 30 becomes aligned with its respective aperture 29 (as shown in Fig. 10) the respective arm 41 springs outwardly to trap the projection 30 in the adjacent aperture 29 thereby locking the two coupling members 23, 31 together. Axial separation of the coupling is then resisted by abutment of the complementary latching surfaces on the two coupling members 23, 31.
The two coupling members 23, 31 are unlockable for axial separation by further relative rotation in said one direction from the locked position (as indicated by arrows E-E in Fig.
10) to disengage the latching means, the arms 41 riding over the projections 30 in a similar manner to that described with respect to the locking operation to take up the position F-F in Fig. 8 in which position the two coupling members 23, 31 may be axially separated. In the locked position relative rotation in the other direction is prevented by abutment of each of the shoulder portions 52 with a respective side wall 57 of the co-operating aperture 29 and compressive axial forces are transmittable by abutment of each of the end faces 45 with the step 43 on each arm 41.
The two coupling members 23, 31 can also be locked together against axial separation by the angular alignment of said latching surfaces and the subsequent axial movement of the two coupling members 23, 31 into interen gagement. In which case interengagement of the two coupling members 23, 31 will cause the projections 30 to ride up the chamfer ends 42 of the arm 41 before springing into engagement with the respective apertures 29 in the arms 41. The coupling members 23, 31 are unlockable for axial separation by relative rotation of one coupling member 23 or 31 relative to the other coupling member 31 or 23 in one direction.
In the second aspect of the invention there is provided a clutch release mechanism including a disengageable coupling as previously described common parts are indicated in the drawings as having reference numeral with the addition of 100.
With reference to Figs. 11-15 there is shown a pull type clutch assembly and a clutch release mechanism 11. The clutch assembly comprising a pressure plate 10 biased towards a flywheel 18 by a diaphragm spring 14 and a driven plate 12 interposed between the flywheel 18 and the pressure plate 12.
The diaphragm spring 14 has an outer Belleville portion from which a plurality of fingers extend radially inwardly. Each of the fingers having an inner surface facing the flywheel 18 and an outer surface facing away from the flywheel 18.
The clutch release mechanism comprises a clutch release member 1 7 for connection to a clutch pedal linkage (not shown) and a disengageable coupling having first and second coupling members 123, 131 to operably connect the clutch release member 17 to the clutch assembly. The clutch release member 17 comprises a release bearing 16 having a non-rotatable part and a rotatable part supported by balls, the rotatable part being formed integral with the second coupling member 131 and a release bearing carrier 19 to support the release bearing 16.
The first coupling member 123 of the disengageable coupling is drivingly connected to the inner periphery of the diaphragm spring 14 by tabs 24 on the annular end portion 140, the tabs 24 extending between adjacent fingers of the diaphragm spring 14. The annular end portion 140 has a curved abutment surface 28 for co-operation with the inner surface of the diaphragm spring 14, against which it is biassed by a Belleville washer 25 acting between the outer surface of the diaphragm spring fingers and a circlip 26 located in groove 27 in each of the arms 141.
The second coupling member 131 has two inwardly directed projections 130 near one end and three recesses 35 at the other end for co-operation with an axially projecting member 36 on the release bearing carrier 19.
A circumferential groove 34 in the outer surface of an end section 32 the second member 131 provides a location for the balls of the release bearing 16 of which it is a part.
The axially projecting member 36 is engageable with one of the recesses 35 to form a locking means that prevents rotation of said rotatable part relative to said non-rotatable part in at least one direction when the clutch release member is moved beyond the normal rest position in a direction opposite to that used during normal operation of the clutch release mechanism. Such movement causes the release bearing 16 to move within the bearing carrier 19 to take up the free play 'P' and allowing the axially extending projection 36 to engage with one of the recesses 35.
With the first coupling member 123 attached to the friction clutch the second coupling member 131 can be locked to it by axially moving the clutch release member 17 beyond the normal rest position in a direction opposite to that shown by arrow A on Fig.
11. This brings the second coupling member 123 into interengagement with the first coupling member 131. Rotation of the first coupling member 123 will axially lock the two coupling members 123, 131 together against axial separation as previously described the second coupling member 131 being held stationary by the afore mentioned locking means.
Movement of the clutch release member 17 in the direction of arrow 'A' allows the free play 'P' to be restored thereby disengaging the axially extending projection 36 from the recess 35 in the second coupling member 131 with which it is engaged. Further movement of the release member 17 in the direction of the arrow 'A' will apply an axial load through the two coupling members 123,131 against the resistance of the diaphragm spring 14 thereby tending to disengage the clutch.
With reference to Figs. 16 and 17 there is shown an alternative locking means including a modified second coupling member 131 A, and a modified release bearing carrier 19A. The modified second coupling member 131 A has two radially outwardly extending L-shaped lugs 70 on its outer surface.
The modified release bearing carrier 1 9A has an abutment face 73 from which extends an abutment member 75. A release lever 72 (shown ghosted for clarity) forms part of the clutch pedal linkage.
The release lever 72 has two tunnions or pins 71 for co-operation with the L-shaped lugs 70 on the second coupling member 131A and the abutment face and member 73 and 75 on the release bearing carrier 19A.
In the normal rest position of the lever 72 the pins 71 are positioned adjacent the abutment face 73 and abutment member 75.
Movement of the lever 72 away from the normal rest position in the direction to disengage the clutch will cause the release bearing carrier 19A to be moved in the direction of arrow B, the pins 71 reacting against the abutment face 73. Rotation of the release bearing carrier 1 9A due to frictional drag in the release bearing is prevented by contact of each of the pins 71 with a respective one of the abutment members 75. Movement of the lever 72 away from the normal rest position in a direction opposite to that used to disengage the clutch will bring each of the pins 71 into contact with a respective one of the L-shaped lugs 70. Further movement of the lever 72 causes the second coupling member 131 A to be displaced in the direction for interengagement with the first coupling member 123.
Rotation in one direction of the first coupling member 123 relative to the second coupling member 131A will lock the two coupling members 123, 131A together against axial separation. The second coupling member 131 A is prevented from rotation in said one direction by abutment of each of the L-shaped lugs 70 with a respective one of the pins 71.
Although the invention has been described with reference to two aspects of a common embodiment it should be realised that it is not limited to the construction shown, the projections for example could be interchanged with the apertures or could be located on the outer surface of the inner one of the members. The spring biasing of the projections into the apertures could also be provided by having separate spring means interposed between the projections and the coupling member upon which the projections are located. It is also envisaged that the locking means could be replaced by a peg and ramp mechanism to automatically rotate one of the members during the locking and unlocking processes.
Furthermore it is envisaged that the release bearing could be attached directly to the fingers of the diaphragm spring and the disengageable coupling be interposed between the release bearing and the clutch release member.
