Description

  The present invention relates to a hydraulic clutch operation for bringing a friction clutch mechanism installed between an output shaft (for example, a crankshaft) of a power generation source (for example, an engine) and an input shaft of a transmission into a connected state or a separated state. The present invention relates to an assembly aid used when the device is assembled to a transmission.

  The hydraulic clutch operating device is generally called, for example, a so-called concentric slave cylinder, a clutch release device, a clutch disengagement device, etc., but in short, a function for operating a friction clutch mechanism It is a part.

  Conventionally, a hydraulic clutch operation for putting a conventionally known friction clutch mechanism connected between a crankshaft of an engine mounted on a vehicle such as an automobile and an input shaft of a transmission into a connected state or a separated state. There is a device.

  This hydraulic clutch operating device uses hydraulic pressure as power for sliding a release bearing in contact with the inner diameter side of a diaphragm spring of a friction clutch mechanism in the axial direction.

  For such a hydraulic clutch operating device, an indirect operation type in which the release fork for pushing the release bearing is operated by the hydraulic cylinder, and a direct operation type in which the release bearing is directly pushed by the hydraulic cylinder (for example, patents) Reference 1 to 3).

  Since the present invention relates to a direct operation type hydraulic clutch operating device, the configuration thereof will be described.

  In this type of hydraulic clutch operating device, a hydraulic cylinder having a substantially cylindrical shape is arranged concentrically on the outer diameter side of the input shaft of the transmission, and a release bearing is provided at the outer end of the piston of the hydraulic cylinder. It has a built-in configuration.

  For example, as shown in Patent Documents 2 and 3, the hydraulic cylinder has a configuration in which an outer sleeve is disposed on the outer diameter side of the inner sleeve, and a cylindrical piston is inserted into an annular space between the opposed sleeves. .

  The outer sleeve is provided with annular wall portions extending radially outward on the side of the transmission case attached to the transmission case, and mounting pieces projecting radially outward at several circumferential positions on the outer periphery of the annular wall portion. The hydraulic cylinder is assembled to the transmission case by bolting the mounting piece to the outer wall surface of the transmission case.

  A radially outward annular wall portion is provided on the proximal end side of the inner sleeve, and the annular sleeve is sandwiched between the annular wall portion of the outer sleeve and the outer wall surface of the transmission case, whereby the inner sleeve is It is fixed to the case.

  An annular space surrounded by the outer peripheral surface of the inner sleeve and its annular wall portion, the inner peripheral surface of the outer sleeve, and the inner end surface of the piston cylinder is a hydraulic chamber.

  In order to seal this hydraulic chamber, a seal ring is attached to the inner end of the piston so that the sliding contact surface between the piston and the outer sleeve and the sliding contact surface between the piston and the inner sleeve are sealed. The contact surface is sealed by interposing an O-ring on the contact surface between the annular wall portion of the sleeve and the annular wall portion of the outer sleeve.

  By the way, in order to ensure the sealing performance of the contact surface by elastically compressing the O-ring, for example, the outer surface (mounting surface) side of the outer sleeve mounting piece is floated from the outer wall surface of the transmission case. Then, the plurality of bolts are screwed with a predetermined tightening torque so that the annular wall portion of the outer sleeve and the annular wall portion of the inner sleeve are pressed against the outer wall surface of the transmission case.

This operation will be described in detail. That is, when the plurality of bolts are screwed in, the outer sleeve mounting pieces at several circumferential positions are elastically bent, and with the elastic restoring force of the plurality of mounting pieces, the outer sleeve annular wall and the inner sleeve ring The wall portion is pressed toward the transmission case, and the O-ring is elastically compressed.
Japanese Utility Model Publication No. 5-57458 JP 2006-90427 A Japanese Patent Publication No. 2004-500530

  In the above conventional example, the O-ring is elastically compressed to ensure the sealing performance of the contact surface between the annular wall portion of the inner sleeve and the annular wall portion of the outer sleeve.

  By the way, with regard to the bolting operation for the outer sleeve's circumferential mounting pieces, for example, all the bolts are temporarily tightened with a torque smaller than the specified tightening torque, and each bolt is gradually tightened in the specified order. This requires troublesome and time-consuming work such as tightening with torque.

  If such a bolting operation is neglected, the bending state of each of the plurality of mounting pieces may not be uniform, and in a severe case, the hydraulic clutch operating device may be assembled to the transmission case in an inclined posture.

  More specifically, the bolting operation is such that the bolt is screwed into the female screw hole of the transmission case with the remaining one hand while the operator holds the hydraulic clutch operating device with one hand. Here, if it is necessary to apply a sealant for preventing oil leakage from the inside of the transmission case or wrap a sealing tape around the screw shaft portion of the bolt, the bolting operation is performed as described above. It is very difficult to do with one hand.

  On the other hand, for example, if a special dedicated tool called a multi-axis nut runner is used, the bolting operation as described above can be performed easily and quickly. However, preparing such a special dedicated tool itself leads to an increase in equipment cost. There is room for improvement here.

  For reference, although not an assembly assisting tool for a hydraulic clutch operating device as in the present invention, for example, Japanese Patent Application Laid-Open No. 2004-34178 discloses that an inclination of an oil pump assembly of an automatic transmission is prevented when the assembly is installed. A jig for disclosing is disclosed.

  Although this technique describes a point for preventing inclination, before that, this technique and the present invention are different in the premise configuration to be the subject of the invention. Therefore, this technique is not a prior art of the present invention, but merely provided as a reference technique.

  The present invention provides an assembly assisting tool for a hydraulic clutch operating device that can support the assembly work easily and accurately by arranging the hydraulic clutch operating device in a proper posture and immovable at the assembly location. It is an object.

  The assembly aid for the hydraulic clutch operating device according to the present invention is detachably fitted in the annular gap between the inner diameter surface of the hydraulic cylinder and the outer peripheral surface of the input shaft in the following hydraulic clutch operating device. A restriction that restricts axial and radial displacement of the hydraulic clutch operating device with respect to the input shaft in a state where the hydraulic clutch operating device is in contact with the transmission case. It has the means.

  The hydraulic clutch operating device to which the assembly assisting tool according to the present invention is used is applied to the inner diameter portion of the diaphragm spring provided in the friction clutch mechanism between the output shaft of the power generation source and the input shaft of the transmission. A release bearing to be contacted, and a cylindrical hydraulic cylinder that slides the release bearing on the input shaft to bring the friction clutch mechanism into a connected state or a separated state. After being arranged concentrically on the radial side, the circumferential locations of the radially outward annular wall provided at one axial end of the outer sleeve, which is a component of the hydraulic cylinder, The case is bolted to an outer wall surface around an inner hole from which a part of the input shaft protrudes.

  The assembly assisting tool according to the present invention is used when performing the bolting described above. Specifically, as a method of using the assembly assisting tool of this configuration, after mounting the assembly assisting tool on the inner diameter side of the hydraulic clutch operating device, the assembly assisting tool equipped with the hydraulic clutch operating device is used for the transmission. It is configured to be mounted on the outer diameter side of the input shaft.

  In this state, when the assembly assisting tool with the hydraulic clutch operating device is mounted on the input shaft of the transmission, the assembly assisting tool has an outer peripheral surface of the input shaft and an inner peripheral surface of the hydraulic cylinder of the hydraulic clutch operating device. The annular gap between the two is almost completely filled. Therefore, in this state, there is almost no “rattling” between the hydraulic clutch operating device and the input shaft, and the hydraulic clutch operating device is not physically tilted with respect to the input shaft.

  Moreover, the axial and radial displacements of the hydraulic clutch operating device relative to the input shaft can be restricted in a state where the hydraulic clutch operating device is in contact with the transmission case using the assembly assisting tool. Even if the operator removes both hands from the assembly aid, the state remains unchanged. Therefore, the operator can perform the bolting operation with both hands.

  As described above, since the support capability by the assembly assisting tool is improved, in the process of bolting the circumferential portions of the annular wall portion of the outer sleeve to the outer wall surface of the transmission case, the bolts with respect to the screw holes of the transmission case are fixed. Initial screwing can be performed easily, and the subsequent bolt screwing operation does not require the troublesome work of tightening the bolts step by step as in the conventional example, and there is no need to use a special dedicated tool. Etc. can be simplified.

  Preferably, the cylindrical portion is set to a length equal to or less than the total length of the hydraulic clutch operating device in a state of being fitted to the inner periphery of the hydraulic clutch operating device.

As a result, the extension cylinder portion is immovable in the axial direction and the radial direction with respect to the input shaft.

  According to such specification, it becomes clear that the configuration of the regulating means is simple, and it is possible to suppress an increase in the manufacturing cost of the assembly assisting tool.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, exemplary embodiments of the invention will be described in detail with reference to the accompanying drawings.

  First, FIG. 1 to FIG. 7 show an embodiment of the present invention. Here, prior to the description of the characteristics of the present invention, an outline of the friction clutch mechanism related to the present invention will be described with reference to FIG.

  FIG. 3 shows a friction clutch mechanism installed in a vehicle such as an automobile. In FIG. 3, 2 is a transmission, 3 is a friction clutch mechanism, and 4 is a hydraulic clutch operating device.

  The illustrated transmission 2 is of a type mounted on a front engine / rear drive (FR) type vehicle.

  The friction clutch mechanism 3 is interposed between a crankshaft (output shaft) 5 of an engine (power generation source) (not shown) and an input shaft (input shaft) 6 of the transmission 2. The input shaft 6 is brought into a connected state in which power can be transmitted, a separated state in which power cannot be transmitted, or a half-connected state (so-called half-clutch) that involves slipping.

  As shown in FIG. 1, the input shaft 6 is supported by an inner hole 22 of the transmission case 21 via a rolling bearing (reference numeral omitted), and a part of the input shaft 6 is opened outside the inner hole 22 of the transmission case 21. It is in a state of protruding from.

  The friction clutch mechanism 3 has a generally known single-plate dry structure, and mainly includes a clutch disk 31, a pressure plate 32, and a diaphragm spring 33.

  The clutch disc 31 is opposed to the flywheel 7 fixed to the outer end of the crankshaft 5 of the engine by being spline-fitted to the tip of the input shaft 6 of the transmission 2 so as to be integrally rotated and axially displaceable. Has been placed.

  The pressure plate 32 is formed of an annular plate disposed to face the clutch disk 31 and is assembled to the outer periphery of the diaphragm spring 33.

  The diaphragm spring 33 is a clutch connected state in which the pressure plate 32 is pressed close to the flywheel 7 side in the natural state to press the clutch disc 31 against the flywheel 7 with the pressure plate 32, and the inner diameter side thereof is in the axial direction. When the pressure plate 32 is reversed by being pressed, the pressure plate 32 is pulled away from the flywheel 7 and the clutch disc 31 is pulled away from the flywheel 7 to be in a clutch disengaged state.

  The hydraulic clutch operating device 4 is a so-called concentric slave cylinder, clutch release device, clutch disconnection device, or the like, and by displacing the pressure plate 32 of the friction clutch mechanism 3 in the axial direction as necessary. The friction clutch mechanism 3 is operated to establish a connected state, a separated state, and a half-connected state.

  The basic operation of the hydraulic clutch operating device 4 is generally known and will be described briefly.

  For example, an operation state of a clutch pedal (not shown) by a driver is recognized by an electronic control unit (ECU), and the electronic control unit controls a hydraulic circuit (not shown) according to the recognition result, Hydraulic oil is supplied to the hydraulic chamber 46 of the hydraulic clutch operating device 4 to bring the friction clutch mechanism 3 into a separated state, or the supply of hydraulic oil to the hydraulic chamber 46 is released to bring the friction clutch mechanism 3 into a connected state. Or a semi-connected state with slipping.

  First, when the friction clutch mechanism 3 is switched from the connected state shown in FIG. 1, appropriate hydraulic oil is supplied from the hydraulic circuit to the hydraulic chamber 46 of the hydraulic clutch operating device 4 through the oil passage 42c.

  As a result, the piston 43 of the hydraulic clutch operating device 4 is pushed outward, and the release bearing 44 mounted on the piston 43 acts to reverse the diaphragm spring 33, so that the pressure plate 32 is removed from the flywheel 7. The crankshaft 5 of the engine and the input shaft 6 of the transmission 2 are separated from each other. As a result, the friction clutch mechanism 3 enters a separated state.

  On the other hand, when the friction clutch mechanism 3 is changed from the separated state to the connected state shown in FIG. 1, the supply of hydraulic oil from the hydraulic circuit is released.

  As a result, the release bearing 44 and the piston 43 of the hydraulic clutch operating device 4 are pushed back by the elastic restoring force of the diaphragm spring 33, so that the hydraulic oil in the hydraulic chamber 46 is returned to the hydraulic circuit through the oil passage 42c. .

  At the same time, the pressure plate 32 is pushed toward the flywheel 7 by the elastic restoring force of the diaphragm spring 33, so that the crankshaft 5 of the engine and the input shaft 6 of the transmission 2 are connected. Thus, the friction clutch mechanism 3 is in a connected state.

  The configuration of the hydraulic clutch operating device 4 will be described in detail. As shown in FIGS. 1 and 2, the hydraulic clutch operating device 4 has a substantially cylindrical outer shape and is concentrically disposed on the outer diameter side of the input shaft 6 of the transmission 2. It mainly includes an inner sleeve 41, an outer sleeve 42, a piston 43, a release bearing 44, and a preload spring 45.

  The inner sleeve 41, the outer sleeve 42, and the piston 43 constitute a hydraulic cylinder.

  The inner sleeve 41 is formed in a cylindrical shape, and is disposed in a non-contact surrounding manner on the outer diameter side of the input shaft 6 of the transmission 2. On the proximal end side in the axial direction of the inner sleeve 41, an annular wall portion 41a extending outward in the radial direction is provided.

  The outer sleeve 42 is formed in a cylindrical shape, and is disposed so as to surround the inner sleeve 41 so as to form an annular space on the outer diameter side.

  An annular wall portion 42 a extending radially outward is provided on the axially proximal end side of the outer sleeve 42. At several places (for example, three places) on the outer circumference of the annular wall portion 42a, mounting pieces 42b for fixing to the transmission case 21 are provided so as to protrude radially outward.

  An oil passage 42c for sending and receiving hydraulic oil to and from a hydraulic circuit (not shown) is provided on the side of one attachment piece 42b among the attachment pieces 42b.

  The piston 43 has a cylindrical shape and is fitted in an annular space between the inner sleeve 41 and the outer sleeve 42 so as to be axially displaceable.

  The release bearing 44 is mounted on the outer diameter side of the small-diameter thin portion on the outer end side of the piston 43 and is in contact with the inner diameter portion of the diaphragm spring 33 of the friction clutch mechanism 3.

  Note that the inner diameter of the inner ring of the release bearing 44 is covered with a small-diameter thin portion of the piston 43, and the release bearing 44 is prevented from coming off by a leaf spring 49.

  The preload spring 45 is interposed in a compressed state between the inner surface of the annular wall portion 42a of the outer sleeve 42 and the receiving seat 50 assembled to the inner ring of the release bearing 44, and the release bearing 44 has its elastic restoring force. The outer ring end face is pressed and urged so that it always abuts against the inner diameter side of the diaphragm spring 33, thereby eliminating the "back".

  A hydraulic chamber 46 formed of an annular space surrounded by the inner sleeve 41, the outer sleeve 42, and the piston 43 is sealed from the outside with a seal ring 47 and an O-ring 48.

  The seal ring 47 is attached to the inner end side of the piston 43 and has a lip that is in sliding contact with the outer peripheral surface of the inner sleeve 41 and the inner peripheral surface of the outer sleeve 42. The hydraulic oil in the hydraulic chamber 46 is prevented from leaking from the outer diameter side and the inner diameter side of the piston 43.

  The O-ring 48 is housed in a state of protruding into a circumferential groove 42d formed on the outer surface of the annular wall portion 42a of the outer sleeve 42, and is pressed against the inner surface of the annular wall portion 41a of the inner sleeve 41. The hydraulic oil in the hydraulic chamber 46 is prevented from leaking from the contact surface between the annular wall portion 41a of the inner sleeve 41 and the annular wall portion 42a of the outer sleeve 42, and foreign matters such as external moisture and dust are in contact with the contact surface. Intrusion into the hydraulic chamber 46 through the surface is prevented.

  By the way, the attachment form of the hydraulic clutch operating device 4 will be described.

  First, in order to align the center of the inner hole 22 of the transmission case 21 and the center of the hydraulic clutch operating device 4, the outer surface of the annular wall portion 42 a of the outer sleeve 42 of the hydraulic clutch operating device 4 has an annular shape. An annular convex portion 25 into which the annular concave portion 42e is fitted is provided around the inner hole 22 in the outer wall surface 23 of the transmission case 21.

  The annular concave portion 42e and the annular convex portion 25 are so-called inlay fitting, and are useful for the alignment.

  Further, in order to ensure the sealing performance of the contact surface between the annular wall portion 41a of the inner sleeve 41 and the annular wall portion 42a of the outer sleeve 42, the O-ring 48 interposed between the contact surfaces is elastically compressed. It has a structure like this.

  Specifically, first, as shown in FIG. 1, in the annular wall portion 42 a of the outer sleeve 42, the inner diameter side region of the annular recess 42 e can be fitted with the annular wall portion 41 a of the inner sleeve 41 slightly protruding. To be retracted or recessed. This is to make it easy to align the inner sleeve 41 with the outer sleeve 42, thereby maintaining the contact state of the lip of the seal ring 47 with both the tubes 41, 42 properly.

  The aforementioned circumferential groove 42d for storing the O-ring 48 is provided on the outer diameter side of the receding region 42f.

  Each outer surface (attachment surface) of the plurality of attachment pieces 42b is also retracted in the same manner as the receding region 42f.

  As a result, the region between the circumferential groove 42d and the annular recess 42e projects in a ring shape, and this ring-shaped projecting portion 42g is the most protruding portion of the annular wall portion 42a of the outer sleeve 42. Yes.

  In such a configuration, for example, when the outer sleeve 42 is simply pressed against the outer wall surface 23 of the transmission case 21 (see FIG. 6), the O-ring 48 is in a natural state. The wall 41a protrudes from the ring-shaped overhanging portion 42g of the outer sleeve 42 and is in contact with the outer wall surface 23 of the transmission case 21, and the ring-shaped overhanging portion 42g and the mounting piece 42b of the outer sleeve 42 are shifted. The machine case 21 is separated from the outer wall surface 23, and a facing gap Δα is formed between the two.

  In this state, for example, as the plurality of bolts 17 are gradually tightened, the O-ring 48 is elastically compressed, and the annular wall portion 41a of the inner sleeve 41 is flush with the annular projecting portion 42g of the outer sleeve 42. The annular projecting portion 42 g of the outer sleeve 42 is fitted to the inner diameter side of the annular convex portion 25 of the transmission case 21.

  Finally, when the bolts 17 are tightened with a prescribed tightening torque, the mounting pieces 42b at several places on the circumference of the outer sleeve 42 are elastically bent to reduce the facing gap Δα, and accordingly, a plurality of mounting pieces The elastic restoring force 42b acts to press the annular wall 42a of the outer sleeve 42 toward the transmission case 21 side.

  Thereby, the state in which the O-ring 48 is elastically compressed is maintained, whereby the sealing performance of the contact surface between the annular wall portion 41a of the inner sleeve 41 and the annular wall portion 42a of the outer sleeve 42 is improved.

  As described above, in order to secure the sealing structure of the hydraulic chamber 46, the assembled state of the hydraulic clutch operating device 4 with respect to the transmission case 21 is important.

  In consideration of such circumstances, in this embodiment, the assembly assisting tool 10 is used when the hydraulic clutch operating device 4 is assembled to the transmission 2.

  In short, the assembling assisting tool 10, in the process of assembling the hydraulic clutch operating device 4 to the transmission 2, keeps the hydraulic clutch operating device 4 from tilting with respect to the input shaft 6 and with respect to the transmission case 21. It is supported so that it is fixedly placed at an appropriate position.

  Specifically, the assembly assisting tool 10 has a cylindrical portion 11 whose outer periphery and inner periphery are circular. The cylindrical portion 11 is provided with an extended cylindrical portion 12 that is coaxially extended on one side in the axial direction. The boundary between the extended cylindrical portion 12 and the cylindrical portion 11 is radially outward. A scissors 13 are provided.

  The thickness of the cylindrical portion 11 is a dimension that fits and fits detachably from the axial direction in an annular gap between the outer peripheral surface of the input shaft 6 and the inner peripheral surface of the inner sleeve 41 that is one component of the hydraulic cylinder. Is set to

  Therefore, the outer diameter dimension of the cylindrical portion 11 (see R1 in FIG. 7) is set slightly smaller than the inner diameter dimension (see r1 in FIG. 7) of the inner sleeve 41 of the hydraulic clutch operating device 4. The inner diameter dimension (see R2 in FIG. 7) of the cylindrical portion 11 is set slightly larger than the outer diameter dimension (see r2 in FIG. 7) of the input shaft 6 of the transmission 2. However, when slight deformation of the cylindrical portion 11 can be expected, it is possible to set R1 = r1 and R2 = r2.

  Further, the axial dimension of the cylindrical portion 11 (see L1 in FIG. 7) is set slightly smaller than the axial dimension of the hydraulic clutch operating device 4 (see L2 in FIG. 7). However, the relationship between L1 and L2 can be set the same, or L1 can be set slightly larger than L2.

  The inner diameter dimension of the extension cylinder part 12 is set to be the same as the inner diameter dimension of the cylinder part 11, but the outer diameter dimension of the extension cylinder part 12 is set larger than the outer diameter dimension of the cylinder part 11. . Therefore, when the cylindrical part 11 is inserted into the inner diameter side of the hydraulic clutch operating device 4 from the axial direction, the extended cylindrical part 12 protrudes outside the hydraulic clutch operating device 4.

  The flange 13 is provided so as to project outward in the radial direction at the boundary between the tubular portion 11 and the extended tubular portion 12.

  The outer diameter dimension of the flange 13 is set larger than the outer diameter dimension of the piston 43 of the hydraulic clutch operating device 4. However, the outer diameter of the flange 13 may be set substantially the same as the outer diameter of the piston 43.

  In addition, the front surface of the flange 13 is flush with the stepped wall surface 14 existing at the boundary between the tubular portion 11 and the extended tubular portion 12. The stepped wall surface 14 is a surface along the radial direction. Therefore, when the cylindrical portion 11 is inserted into the inner diameter side of the hydraulic clutch operating device 4 from the axial direction, the front surface of the rod 13 and the stepped wall surface 14 are the other axial end surfaces of the hydraulic clutch operating device 4 (the outer end surface of the piston 43). It comes to contact | abut.

  And the circumferential groove 12a, 12b is provided in two places away in the axial direction on the inner peripheral surface of the extension cylinder part 12, O-rings 51, 51 are put in the circumferential groove 12a, 12b. Yes. The number of the O-rings 51 and 51 and the circumferential grooves 12a and 12b can be set arbitrarily.

  The O-rings 51 and 51 protrude from the openings of the circumferential grooves 12a and 12b. Therefore, in a state where the extension cylinder portion 12 is fitted to the outer diameter side of the input shaft 6, the O-rings 51 and 51 are pressed against the outer peripheral surface of the input shaft 6 in a state of being elastically deformed. The tightening allowance can be set as appropriate.

  That is, the O-rings 51, 51 have the annular wall portion 41 a of the inner sleeve 41 abutted against the transmission case 21 when the hydraulic clutch operating device 4 is assembled to the transmission case 21 using the assembly assisting tool 10. When in the state, it functions to restrict axial and radial displacements of the cylindrical portion 11 and the hydraulic clutch operating device 4 with respect to the input shaft 6. As is clear from this, the O-rings 51 and 51 correspond to the restricting means and the elastic body described in the claims.

  Incidentally, oil sumps 15 and 16 are provided on the outer peripheral surface and the inner peripheral surface of the cylindrical portion 11, respectively.

  The oil sumps 15 and 16 are both continuous spiral grooves and are formed over the entire length of the cylindrical portion 11. The groove as the oil reservoir 15 on the outer diameter side and the groove as the oil reservoir 16 on the inner diameter side are provided in a state shifted in the axial direction. In this way, both the oil sumps 15 and 16 can be provided even when the thickness of the cylindrical portion 11 must be reduced.

  Such an assembly assisting tool 10 can be manufactured as a molded product such as a synthetic resin. However, the material of the assembly assisting tool 10 is not particularly limited, but it is made softer than the material of the inner sleeve 41 (for example, stainless steel or aluminum alloy), and eliminates the aggression that causes the inner sleeve 41 to be plastically deformed during use. It is preferable to select with consideration.

  Next, a procedure and a state when the hydraulic clutch operating device 4 is assembled to the transmission 2 using the assembly assisting tool 10 having such a configuration will be described in detail with reference to FIGS. 5 to 7.

  First, in the state of the assembling auxiliary tool 10 alone, oil and fat (for example, appropriate grease, lubricating oil, rust inhibitor, etc.) are applied to the outer peripheral surface and inner peripheral surface of the cylindrical portion 11 and the inner peripheral surface of the extension cylindrical portion 12. Apply.

  As shown in FIG. 5, the cylindrical portion 11 of the assembly assisting tool 10 is fitted on the inner diameter side of the inner sleeve 41 of the hydraulic clutch operating device 4.

  By the way, by specifying the relationship between the outer diameter of the cylindrical portion 11 and the inner diameter of the inner sleeve 41 as described above, a slight gap is formed between the outer peripheral surface of the cylindrical portion 11 and the inner peripheral surface of the inner sleeve 41. Therefore, there is almost no “rattling” between the tubular portion 11 and the inner sleeve 41. As a result, the assembly assisting tool 10 is not physically inclined to the hydraulic clutch operating device 4.

  However, in order to ensure such a mounting state, although it is difficult to fit the cylindrical portion 11 into the inner sleeve 41, as described above, the oil applied to the outer peripheral surface of the cylindrical portion 11 is Since the slipping of the mating surfaces is made smooth at the time of fitting, it can be easily fitted.

  When such fitting is performed, the oil applied to the outer peripheral surface of the cylindrical portion 11 is scraped off by the inner sleeve 41, but in the oil sump 15 formed on the outer peripheral surface of the cylindrical portion 11. The fats and oils remain and are retained.

  Thereafter, as shown by the white arrow in FIG. 5, the cylindrical portion 11 of the assembly assisting tool 10 to which the hydraulic clutch operating device 4 is attached is fitted to the outer diameter side of the input shaft 6 of the transmission 2.

  At this time, the operator holds the annular wall part 41a of the inner sleeve 41 of the hydraulic clutch operating device 4 as shown in FIG. What is necessary is just to gradually push in until it contacts the outer wall surface 23 of the transmission case 21.

  In this pushed-in state, the free end of the cylindrical portion 11 of the assembly assisting tool 10 is in a separated state without contacting the outer wall surface 23 of the transmission case 21, and the outer sleeve 42 is attached. The piece 42b also faces the outer surface 23 of the transmission case 21 in a slightly separated state without contacting the outer wall surface 23 of the transmission case 21 due to the presence of the O-ring 48.

  At this time, as described above, by specifying the relationship between the inner diameter dimension of the cylindrical portion 11 of the assembly assisting tool 10 and the outer diameter dimension of the input shaft 6, the inner peripheral surface of the cylindrical portion 11 is changed to the outer periphery of the input shaft 6. Since the surface is set so as to be fitted through a slight gap, there is almost no “rattling” between the tubular portion 11 and the input shaft 6.

  At this point, the cylindrical portion 11 of the assembly assisting tool 10 has a shape that substantially completely fills the annular gap between the outer peripheral surface of the input shaft 6 and the inner peripheral surface of the inner sleeve 41 of the hydraulic clutch operating device 4. Therefore, the assembly assisting tool 10 and the hydraulic clutch operating device 4 are not physically tilted with respect to the input shaft 6, that is, the hydraulic clutch operating device 4 is centered with respect to the input shaft 6 and becomes substantially immobile. . In addition, the annular wall portion 41a of the inner sleeve 41 is held in contact with the outer wall surface 23 of the transmission case 21, and the mounting piece 42b of the outer sleeve 42 is separated from the outer wall surface 23 of the transmission case 21. In this state, the opposing gap is held substantially constant in the circumferential direction.

  However, if such an arrangement state is ensured, the assembly aid 10 becomes difficult to push in, but as described above, the oil applied to the inner peripheral surface of the cylindrical portion 11 is pushed in. Since the sliding of the mating surface is made smooth at the time, it can be pushed in easily.

  Moreover, when such a pushing operation is performed, the oil applied to the inner peripheral surface of the cylindrical portion 11 is scraped by the input shaft 6, but the oil formed on the inner periphery of the cylindrical portion 11. The oil and fat remains and is retained in the reservoir 16.

  And in the state pushed in as mentioned above, even if an operator separates both hands from the assembly assisting tool 10, the assembly assisting tool 10 moves the hydraulic clutch operating device 4 in the axial direction and the radial direction with respect to the input shaft 6. It is designed to hold it immobile.

  The reason will be explained. Since the O-rings 51, 51 provided on the inner diameter side of the extension cylinder portion 12 of the assembly assisting tool 10 are pressed against the outer peripheral surface of the input shaft 6 in a state of being elastically compressed and deformed, the O-ring 51, 51 becomes a padding, and the assembly assisting tool 10 and the hydraulic clutch operating device 4 are displaced in the axial direction and the radial direction with respect to the input shaft 6 by the radially inward binding force of the O-rings 51, 51. It is impossible to do that.

  When the hydraulic clutch operating device 4 and the assembly assisting tool 10 are fixed to the input shaft 6 in this manner, bolts are respectively inserted into the bolt insertion holes of the mounting pieces 42b at several circumferential positions on the outer sleeve 42. After inserting 17, the bolt 17 is screwed into each screw hole 24 of the outer wall surface 23 of the transmission case 21 to fix the hydraulic clutch operating device 4 to the transmission case 21.

  At the stage where the bolt 17 is fastened, the assembly assisting tool 10 and the hydraulic clutch operating device 4 are fixed to the input shaft 6 and the transmission case 21 even if the operator releases both hands from the assembly assisting tool 10. Therefore, the operator can relatively easily screw the plurality of bolts 17 into the respective screw holes 24 of the outer wall surface 23 of the transmission case 21 with both hands.

  As for the screwing work following such initial screwing, there is no need to perform troublesome work such as tightening a plurality of bolts 17 in a stepwise manner as in the conventional example, or to use a special dedicated tool. All that is required is to tighten the bolts 17 in sequence.

  By the way, when the screw hole 24 penetrates into and out of the transmission case 21 as in the illustrated example, the oil in the transmission case 21 oozes out from the screwed portion between the screw hole 24 and the bolt 17. Therefore, in such a case, it is necessary to apply a sealing agent around the screw shaft portion of the bolt 17 or wind a sealing tape in advance. In such a case, the initial screwing of the bolt 17 into the screw hole 24 becomes difficult, but if the operator can use both hands as described above, the initial screwing of the bolt 17 into the screw hole 24 is relatively easy. Therefore, workability is greatly improved.

  After the hydraulic clutch operating device 4 is assembled to the transmission case 21 in this way, the assembly assisting tool 10 is removed from the hydraulic clutch operating device 4 assembled to the transmission case 21 as shown in FIG. In that case, what is necessary is just to grasp the extension cylinder part 12 of the assembly | attachment auxiliary tool 10, and to pull it to this side. However, you may make it pull by hooking a finger on the collar 13 of the assembly assisting tool 10.

  In this removal process, the oil and fat held in the oil sumps 15 and 16 provided on both the outer peripheral surface and the inner peripheral surface of the cylindrical portion 11 of the assembly assisting tool 10 are transferred to the cylindrical portion 11 and the inner sleeve 41. The cylindrical portion 11 of the assembly aid 10 is smoothly inserted between the input shaft 6 and the inner sleeve 41 in order to adhere to the fitting surface of the cylindrical portion 11 and the fitting surface of the cylindrical portion 11 and the input shaft 6. And it can be pulled out easily.

  As described above, when the assembly assisting tool 10 of the present embodiment to which the features of the present invention are applied is used, when the hydraulic clutch operating device 4 is attached to the transmission case 21, the hydraulic clutch operation is performed on the transmission case 21. It is possible to support the apparatus 4 so that the assembling work can be performed easily and accurately by arranging the apparatus 4 in an appropriate posture and immovable.

  That is, in the process of fastening the plurality of bolts 17 in the above state, even if the operator removes both hands from the assembly assisting tool 10, the posture of the hydraulic clutch operating device 4 is inclined as in the conventional example, or the transmission case 21 It is possible to avoid a problem that the annular wall portion 41a of the inner sleeve 41 of the hydraulic clutch operating device 4 is separated from the outer wall surface 23.

  Therefore, the operator can perform the initial screwing of the bolt 17 into the screw hole 24 of the transmission case 21 with both hands instead of one hand as in the conventional example, and the conventional screwing operation of the bolt 17 is also conventional. In this way, it is not necessary to perform a troublesome operation such as tightening a plurality of bolts 17 step by step, and it is possible to simplify the operation by eliminating the need to use a special dedicated tool.

  Accordingly, the hydraulic clutch operating device 4 can be easily and accurately assembled to the transmission 2, so that the work time required for assembling the hydraulic clutch operating device 4 to the transmission 2 can be shortened. . As a result, it is possible to greatly contribute to improvement in productivity when producing the transmission 2 or improvement in maintenance workability when exchanging and repairing the hydraulic clutch operating device 4.

  In addition, this invention is not limited only to the said embodiment, All the deformation | transformation and application included in the range equivalent to the claim and the said range are possible.

  (1) In the above embodiment, the transmission 2 mounted on an FR (front engine / rear drive) type vehicle is taken as an example, but an FF (front engine / front drive) type vehicle, MR (mid engine) The present invention can be applied to any transmission that is mounted on a rear drive vehicle or an RR (rear engine / rear drive) vehicle.

  (2) In the assembly assisting tool 10 of the above-described embodiment, an example in which the oil sumps 15 and 16 are spiral grooves is given, but the shape is not particularly limited.

  For example, as other examples of the oil sumps 15 and 16, although not shown, a plurality of circular grooves arranged side by side at predetermined intervals in the axial direction, or straight lines along the axial direction at several circumferential points. It may be a groove having a shape, or may be a plurality of recesses that are irregularly or regularly scattered. In addition, oil sumps 15 and 16 having various shapes may be combined.

  Even in such a case, it is possible to obtain basically the same operations and effects as the assembly assisting tool 10 of the above embodiment.

  In addition, in the assembly assisting tool 10 of the above-described embodiment, either one or both of the oil sumps 15 and 16 can be eliminated. In that case, when removing the assembly assisting tool 10 from the hydraulic clutch operating device 4, the tubular portion 11 itself of the assembly assisting tool 10 is attached so that it can be easily removed and the inner sleeve 41 is not damaged. It is formed of a material having lubricity (for example, a fluorine-based synthetic resin or a soft metal), or the outer peripheral surface and the inner peripheral surface of the cylindrical portion 11 are coated with a material having the above-described lubricity in a film shape. Is preferable. Also in this case, it is possible to obtain basically the same operations and effects as the assembly assisting tool 10 shown in the above embodiment.

  (3) In the assembly assisting tool 10 of the above-described embodiment, an example in which the O-rings 51 and 51 are used as the restricting means is given. For example, as shown in FIGS. 8 and 9, the magnetic body 52 such as a permanent magnet, 52 can be used.

  The magnetic bodies 52 and 52 are put into holes 12c and 12d penetrating in the radial direction provided at two positions opposed to each other by 180 degrees at a predetermined position in the axial direction of the extension cylinder portion 12. The number of magnetic bodies 52, 52 used is arbitrary.

  In the case of this embodiment, when assembling the hydraulic clutch operating device 4 to the transmission case 21 using the assembly assisting tool 10, first, the magnetic bodies 52, 52 are inserted into the holes 12 c, 12 d of the extension cylinder portion 12 of the assembly assisting tool 10. The hydraulic clutch operating device 4 is mounted on the cylindrical portion 11 in a state where the valve is not inserted.

  The hydraulic clutch operating device 4 and the assembly assisting tool 10 thus configured are fitted to the outer diameter side of the input shaft 6, and the hydraulic clutch operating device 4 is pressed against the transmission case 21, and then this state is changed. The magnetic bodies 52 and 52 are put into the holes 12c and 12d of the extension cylinder portion 12 of the assembly assisting tool 10 while being held.

  Then, the magnetic bodies 52, 52 projecting from the inner diameter side openings of the holes 12c, 12d are magnetically attracted to the input shaft 6, whereby the assembly aid 10 is attached to the input shaft 6 in the axial direction and the radial direction. The hydraulic clutch operating device 4 held by the assembly assisting tool 10 is made immobile while maintaining an appropriate relative position with respect to the transmission case 21.

  As described above, in this embodiment as well, the hydraulic clutch operating device 4 is centered with respect to the input shaft 6 and then properly positioned with respect to the transmission case 21 as in the above embodiment. It can be held as it is. Since it can hold | maintain in such a state, the operation | work which fastens the volt | bolt 17 can be performed with both hands, and it will result in improving work efficiency.

  (4) About the magnetic bodies 52 and 52 of said (3), as shown, for example in FIG. 10, it can be set as the magnetic body 53 of a substantially "U" shape by side view.

  When such a single magnetic body 53 is used, the notches 12e and 12f are provided along two directions perpendicular to the longitudinal direction of the extension cylinder part 12 at two positions opposed to each other by 180 degrees in the extension cylinder part 12 of the assembly assisting tool 10. In addition, holes 12c and 12d penetrating in the radial direction are provided in the middle in the longitudinal direction of the notches 12e and 12f.

  In this example, the timing for attaching the magnetic body 53 to the extension cylinder portion 12 is the same as that in the example (3). However, as a mounting form of the magnetic body 53, the magnetic body 53 may be slidably mounted on the notches 12e and 12f from a direction orthogonal to the longitudinal direction of the extension cylinder portion 12. By doing so, a part of the magnetic body 53 is exposed from the holes 12c and 12d, and the exposed part of the magnetic body 53 is magnetically attracted to the input shaft 6.

  (5) In the assembly assisting tool 10 of the above embodiment, an example in which the O-ring 51 and the magnetic bodies 52 and 53 are used as the restricting means is given. It is possible to devise as follows.

  For example, as shown in FIG. 11, the outer peripheral surface of the cylindrical portion 11 of the assembly assisting tool 10 is tapered.

  An operation in the case where the hydraulic clutch operating device 4 is assembled to the transmission case 21 using such an assembly assisting tool 10 will be described.

  First, in the state of the assembling auxiliary tool 10 alone, oil and fat (for example, appropriate grease, lubricating oil, rust inhibitor, etc.) are applied to the outer peripheral surface and inner peripheral surface of the cylindrical portion 11 and the inner peripheral surface of the extension cylindrical portion 12. Apply.

  The cylindrical portion 11 of the assembly assisting tool 10 is fitted to the inner diameter side of the inner sleeve 41 of the hydraulic clutch operating device 4. At this time, since the outer peripheral surface of the cylindrical part 11 is tapered, the entire cylindrical part 11 is slightly elastically deformed radially inward as the fitting depth of the cylindrical part 11 increases.

  Thereafter, the cylindrical portion 11 of the assembly assisting tool 10 to which the hydraulic clutch operating device 4 is attached is fitted to the outer diameter side of the input shaft 6 of the transmission 2.

  At this time, the operator holds the annular wall part 41a of the inner sleeve 41 of the hydraulic clutch operating device 4 as shown in FIG. What is necessary is just to gradually push in until it contacts the outer wall surface 23 of the transmission case 21.

  In this pushed-in state, the free end of the cylindrical portion 11 of the assembly assisting tool 10 is in a separated state without contacting the outer wall surface 23 of the transmission case 21, and the annular shape of the outer sleeve 42. The wall portion 42a also faces the outer wall surface 23 of the transmission case 21 in a slightly separated state without contacting the outer wall surface 23 of the transmission case 21 due to the presence of the O ring 48.

  At this time, as described above, the cylindrical portion 11 of the assembly assisting tool 10 is in a state of biting like a wedge into the annular gap between the inner sleeve 41 and the input shaft 6 of the hydraulic clutch operating device 4. The assembly assisting tool 10 and the hydraulic clutch operating device 4 are not physically tilted with respect to the shaft 6, that is, the hydraulic clutch operating device 4 is centered with respect to the input shaft 6 and becomes substantially immobile. In addition, the annular wall portion 41a of the inner sleeve 41 is held in contact with the outer wall surface 23 of the transmission case 21, and the mounting piece 42b of the outer sleeve 42 is separated from the outer wall surface 23 of the transmission case 21. In this state, the facing gap Δα is held substantially constant in the circumferential direction.

  In such a state, even if the operator releases both hands from the assembly assisting tool 10, the assembly assisting tool 10 and the hydraulic clutch are operated with respect to the input shaft 6 by the wedge action of the cylindrical portion 11 whose outer peripheral surface is tapered. The device 4 is fixed so as not to be displaced in the axial direction and the radial direction.

  When the hydraulic clutch operating device 4 and the assembly assisting tool 10 are fixed to the input shaft 6 in this manner, bolts are respectively inserted into the bolt insertion holes of the mounting pieces 42b at several circumferential positions on the outer sleeve 42. After inserting 17, the bolt 17 is screwed into each screw hole 24 of the outer wall surface 23 of the transmission case 21 to fix the hydraulic clutch operating device 4 to the transmission case 21.

  At the stage where the bolt 17 is fastened, the assembly assisting tool 10 and the hydraulic clutch operating device 4 remain stationary with respect to the input shaft 6 and the transmission case 21 even if the operator releases both hands from the assembly assisting tool 10. As a result, the operator can relatively easily screw the plurality of bolts 17 into the screw holes 24 of the outer wall surface 23 of the transmission case 21 with both hands.

  As for the screwing work following such initial screwing, there is no need to perform troublesome work such as tightening a plurality of bolts 17 in a stepwise manner as in the conventional example, or to use a special dedicated tool. All that is required is to tighten the bolts 17 in sequence.

  After the hydraulic clutch operating device 4 is assembled to the transmission case 21 in this manner, the assembly assisting tool 10 is removed from the hydraulic clutch operating device 4 assembled to the transmission case 21. In that case, what is necessary is just to grasp the extension cylinder part 12 of the assembly | attachment auxiliary tool 10, and to pull it to this side. However, you may make it pull by hooking a finger on the collar 13 of the assembly assisting tool 10.

  As described above, in this embodiment as well, the hydraulic clutch operating device 4 is centered with respect to the input shaft 6 and then properly positioned with respect to the transmission case 21 as in the above embodiment. It can be held as it is. Since it can hold | maintain in such a state, the operation | work which fastens the volt | bolt 17 can be performed with both hands, and it will result in improving work efficiency.
