DOG UNIT FOR PLATE CLUTCH SYSTEMS
[20] The present invention relates to a dog unit for a plate clutch system, and in particular, comprising a dog plate and a clutch basket, wherein the dog plate is provided with an external gear, and the housing of the clutch basket has a shape and at least a section for the external gear of the dog plate. The present invention relates to a dog unit for a plate clutch system, in which a gear having a complementary function is provided and into which a dog plate can be inserted into a clutch basket.
[21] Generally, the dog unit is used for the drive connection of the plate clutch in the double clutch.
[22] The dog unit of the prior art basically consists of a dog plate and a clutch basket. At this time, the dog plate has an outer gear formed in the circumferential direction. The clutch basket is provided with an internal gear that complements the outer gear of the dog plate in terms of form and function at least in sections. In order to assemble the dog unit, the dog plate with external gear is inserted into the inner gear of the clutch basket by press fitting.
[23] In the inserted state the dog plate and the clutch basket have a common axis of rotation. Especially when the dog unit rotates at high speed, the clutch basket is essentially radially enlarged in relation to the dog plate. In other words, when the rotation speed is high, the backlash between the inner gear of the clutch basket and the outer gear of the dog plate becomes large. This produces a rattling noise, especially when the torque is in a vibrating state.
[24] An object of the present invention, which is based on the known art, is to provide a dog unit to significantly reduce the noise.

[25] The present invention to solve the above problems,
[26] A dog plate and a clutch basket are included, and the dog plate is provided with an external gear, and the housing of the clutch basket has an internal gear that complements the shape and function of at least sections of the external gears of the dog plates 3 and 14. A dog unit for a plate clutch system, wherein the dog unit for inserting the dog plate into the clutch basket is provided, wherein the dog unit for the plate clutch system, in which the inner gear and the outer gear are engaged with each other at least in sections, is provided. to provide.
[27] The main object of the present invention, which is based on the dog unit of the prior art, is to utilize the expansion of the different centrifugal directions of the clutch basket and the dog plate so that the external gear and the internal gear are at least interlocked under the influence of the centrifugal force. Due to the centrifugal and / or tangential engagement, at least the areas of the inner gear are pressed towards those areas in the effective engagement of the external gear under the influence of the centrifugal force. This results in a press fitting without backlash between the outer gear and the inner gear. Therefore, the expansion of backlash between the external gear and the internal gear known in the art is eliminated under the influence of the centrifugal force according to the present invention.
[28] How the engagement between the external gear and the internal gear is performed is not important in the principles of the present invention. For example, at least one gear tooth of the internal gear may engage a gap in the at least one gear or gear of the external gear. In addition, at least one gear tooth of the external gear may engage the clearance of at least one gear or gear of the internal gear.
[29] According to a preferred embodiment, the outer surface of the clutch basket housing is engaged by the portions of the outer gear of the dog plate at least by section. Its particular advantage is that under the influence of centrifugal force, not only the backlash-free connection between the external gear and the internal gear is created, but also the expansion and deformation of all clutch baskets is significantly reduced. This is because the clutch basket is supported by the dog plate at least section by engagement of the external gear on the outer surface.
[30] Through the reduction of the centrifugal stress in the clutch basket according to the present invention, it is possible to technically produce the clutch basket simply (and therefore inexpensively). For example, it can be produced by deep drawing processing or deformation processing. Thus, the housing of the clutch basket is formed of a profile part at least at the site of the inner gear.
[31] According to a preferred form of the invention, the clutch basket is provided with at least one first slit recess and / or at least one second slit recess. The first and / or second type of slit can be provided in the gear area or in the crevice area. The slit in the first manner according to the invention is basically engaged by at least the part of the outer gear of the dog plate. At least one gear tooth of the internal gear, at least one gear tooth of the dog plate, may be provided with a slit engagement. Alternatively, at least one gear tooth gap of the inner gear of the clutch basket may be provided with an entry where the at least one gear tooth of the outer gear of the dog plate may engage. The slit in the second way allows the clutch basket to be elastically deformed like a spring.
[32] According to a particularly preferred embodiment, said at least one first or second way slit extends to the shaft end of the clutch basket. The advantage of this is that the dog plate and the clutch basket can be assembled more simply and the clutch basket has a high elasticity.
[33] According to another embodiment, it is particularly preferred that the external gear has an oversize at least in part in the circumferential direction with respect to the internal gear (or with respect to the external gear). Thus, for example, the outer gear of the dog plate assembled to an oversize is centrifugally directed at the dog plate, together with a slit in at least one second manner (e.g., extending to the shaft end of the clutch basket). And / or cause an initial stress of the clutch basket acting circumferentially. This is especially desirable when you need to reduce rattling or buzzing noises at low rotational speeds (when the effect of the centrifugal force is less effective).
[34] According to another particularly preferred embodiment, the at least one flank of the outer gear, along with the flanks of the inner gear that complements the shape and function, is a sliding surface at least sectioned with respect to the centrifugal direction of the dog plate and the clutch basket. Make By the oblique flank, there is basically a backlash-free fitting between the outer gear and the inner gear at high or low dog plate rotation speeds. According to a particular formation, both flanks of at least one gear tooth of the outer or inner gears extend conically in at least a section centrifugally.
[35] According to another embodiment of the connection, at least one flank of the external or internal gear is provided with notches and / or protrusions. The addendum or the dedendum of the notch and the internal gear or the external gear may be at least interlocked with each other. Thereby, for example, when the rotational speed is low or when the rotational speed is high, it is possible to connect the dog plate and the clutch basket without backlash. Thus, for example, when the rotational speed is low, it is possible to eliminate backlash by the protruding portion due to the conical flank. In addition, when the rotational speed is high, it is possible to eliminate backlash due to the engagement of the outer gear and the inner gear in each section of the notch (or protrusion) and the appendage (or dedendum).
[36] The invention is illustrated in detail by the drawings and various embodiments.
[37] 1 shows a dog unit 1 of the invention for use in a plate clutch system. The dog unit 1 is composed of a clutch basket 2 and a dog plate 3. Basically the rotationally symmetrical dog plate 3 is formed from sheet metal deformable parts in this embodiment. Basically the rotationally symmetrical clutch basket 2 is also manufactured from sheet metal deformation (eg deep drawing). The inner gear 4 provided in the circumferential direction in the housing of the clutch basket 2 is basically formed of gears 5 at equal intervals from each other. The spacing of the gears 5 is determined by the gear gap 6.
[38] The dog plate 3 has gears 7. The gears 7 are basically arranged in the circumferential direction at equal intervals from each other. The gears 7 form the outer gear 8 of the dog plate 3. The outer gear 8 of the dog plate 3 and the inner gear 4 of the clutch basket 2 are formed complementarily in shape and function at each of the gears 5 and 7. In the state where the dog unit 10 is assembled, the outer gear 8 and the inner gear 4 mesh with each other. In the assembled state, the clutch basket 2 and the dog plate 3 have a common axis of rotation.
[39] According to the invention the inner gear 4 of the clutch basket 2 is engaged by the outer gear 8 of the dog plate 3 at least section by section. In this embodiment, the clutch basket 2 has a slit inlet 10 of the first manner at the site of each gear tooth 5. At this time, each of the gears of the outer gear 8 of the dog plate 3 to be engaged with the outer gear 8 and the inner gear 4 at least at intervals in the slit 10 of each first method. It is engaged by this (7). At this time, each gear tooth 7 of the outer gear 8 of the dog plate 3 has two flanks 11 formed in a conical shape with each other. At this time, each gear tooth 7 is tapered in the rotation center (9) direction. Each flank 11 also represents a notch 12. The notch 12 is engaged by the addendum segment 28 of the inner gear 4 of the clutch basket 2. In the present embodiment, the addendum segment 28 is basically formed by the peripheral portion of the slit 10 of the inner gear 4 of the clutch basket 2.
[40] When there is a rotational movement at high speed while rotating the center of rotation 9, in the dog unit 1 according to the known art, an enlargement of the clutch basket 2 occurs in relation to the dog plate 3. According to the invention, the addendum segment 28 engages the notch 12 provided in the flank 11 of the gear tooth 7 of the outer gear 8. Also according to the invention, due to the conical shape of both flanks 11 of each gear tooth 7 and the conical shape of the flanks 13 of the internal gear 4, the flank of the inner gear 4 facing outwards basically. Movement in the centrifugal direction of (13) is remarkably prevented. This prevents the above mentioned expansion. Therefore, expansion of the centrifugal direction of the clutch basket 2 known in the art no longer occurs.
[41] 2 shows another dog plate 14 according to the invention. The dog plate 14 has an external gear 15. The outer gear 15 is formed of gears 16 at equal intervals from each other. The spacing of two adjacent gears 16 is defined by the gear gap 27. The clutch basket 17 has an inner gear 18 extending in the circumferential direction. The internal gears 18 are basically formed of gears 19 at equal intervals from one another. The spacing between two adjacent gears 19 is defined by the gear tooth clearance 20. In this embodiment, not only the portions of each gear tooth 19 but also the portions of each gear tooth 20 of the gap 20 and the slit of the first manner 21 and the slit of the first manner 22 ) Is provided. The slits 22 of the first manner are respectively engaged by the gear teeth 16 of the dog plate 14.
[42] In this embodiment, the gears 16 of the dog plate 14 are manufactured to be oversized in the circumferential direction with respect to the inner gear 1 of the clutch basket 17. By means of the slit 21 of the second manner in the gears 19 of the clutch basket 17, the clutch basket 17 itself is elastically resilient with respect to the dog plate 14. Have Both plates 23 of each gear tooth 16 of the dog plate 14 extend in a conical shape when viewed in the centrifugal direction. The notch 25 is formed in the site | part of each flank 23 of each gear tooth 16 of the dog plate 14. The notches are respectively engaged by dedendum segments 29. The dedendum segment 29 is formed by the peripheral portion of the geared slit 22 of the first way of the clearance 20.
[43] When the rotational speed is low, since the plates 23 of the gears 16 of the dog plate 14 are tapered outwardly in the centrifugal direction and are formed in a conical shape, the external gear 15 with respect to the inner gear 18 is also provided. Since the c) is manufactured to be oversized in the circumferential direction, the clutch basket 17 basically has no backlash and has an initial stress relatively elastically with respect to the dog plate 14. When the rotational speed is high while rotating the center of rotation 26, the inner gear 18 of the clutch basket 17 is in contact with the gear teeth 16 of the outer gear 15 together with the dedendum segment 29 as a result of the centrifugal force action. It is pressed into the notch 25. There is basically no backlash press fitting between the outer gear 15 of the dog plate 14 and the inner gear 18 of the clutch basket 17.
[44] 3 shows a state where the perspective view of the embodiment according to FIG. 2 is not assembled. A dog plate 14 with an external gear 15 and a clutch basket 17 with an internal gear 18 can be seen. Also shown is a slit of the first type 22 in the internal gear area. The slit inlet 22 of the first manner extends to the shaft end of the clutch basket. The slit-in place 21 of the second manner is not shown.
[45] When the dog unit rotates at high speed, the clutch basket is basically enlarged in the centrifugal direction with respect to the dog plate, i.e., when the rotation speed is high, the backlash between the inner gear of the clutch basket and the outer gear of the dog plate becomes large. Thus, the present invention significantly reduces the rattling noise, especially when the torque is in a vibrating state.
