A lubricating device for a clutch release mechanism will be specifically described below as a first embodiment of the present invention with reference to the drawings. In addition, this invention is not limited to embodiment described below.

(First embodiment)
The lubricating device of the first embodiment prevents sliding problems (e.g., increased friction, abnormal noise, etc.) caused by grease flowing out from the fork grease lubricating portion in the MT clutch housing and contamination by foreign matter after a manual transmission vehicle is flooded or travels across a river. It is used to perform low-cost, short-time inspection and grease injection maintenance for sliding defects associated with it.

FIG. 1 is a diagram schematically showing the clutch release mechanism of the first embodiment. As shown in FIG. 1, the clutch device 1 includes a clutch body 10 for connecting and disconnecting power, a clutch release mechanism 20 for operating the clutch body 10, and a clutch housing 30 for housing the clutch body 10 therein. composed of For example, the clutch device 1 is mounted on a manual transmission vehicle and arranged between the engine and the transmission.

Note that the X direction shown in FIG. 1 represents an axial direction along the center axis, and the Z direction represents a direction orthogonal to the center axis (sometimes referred to as a radial direction or a height direction). When the Z direction is the height direction, the upper side may be referred to as the distal side, and the lower side may be referred to as the proximal side. Furthermore, the Y direction, which will be described later, represents a direction orthogonal to the X direction and the Z direction. The Y direction may be described as the width direction.

The clutch body 10 includes a clutch disk 11, a clutch cover 12, a pressure plate 13, a diaphragm spring 14, and a release bearing 15.

The clutch disc 11 has a friction surface (clutch facing) sandwiched between the pressure plate 13 and the flywheel 16, and is spline-fitted with the input shaft 3 of the transmission. The frictional force between the friction surface of the clutch disc 11 and the flywheel 16 transmits the rotation of the flywheel 16 to the input shaft 3 . A flywheel 16 is bolted to the crankshaft 2 of the engine, and the flywheel 16 and the crankshaft 2 rotate integrally.

The clutch cover 12 is provided so as to cover the outer peripheral side of the clutch disc 11 and rotates integrally with the pressure plate 13 and the diaphragm spring 14 . The pressure plate 13 is provided between the friction surface of the clutch disc 11 and the diaphragm spring 14 . The diaphragm spring 14 is a member for pressing the friction surface of the clutch disc 11 toward the flywheel 16 via the pressure plate 13, and is provided on the side opposite to the friction surface of the clutch disc 11 with respect to the pressure plate 13. there is A peripheral portion of the diaphragm spring 14 is connected to the pressure plate 13 , and a central portion of the diaphragm spring 14 is connected to the release bearing 15 . This allows the diaphragm spring 14 to press the pressure plate 13 .

When the clutch body 10 is engaged, the pressure plate 13 presses the friction surface of the clutch disc 11 toward the flywheel 16 by the elastic force of the diaphragm spring 14 . As a result, a frictional force is generated between the friction surface of the clutch disk 11 and the flywheel 16 , and a connection state is established in which the rotation of the flywheel 16 is transmitted to the clutch disk 11 .

When the clutch body 10 is released, the release bearing 15 presses the central portion of the diaphragm spring 14 , thereby displacing the peripheral portion of the diaphragm spring 14 away from the flywheel 16 . At this time, the pressure plate 13 is pulled away from the flywheel 16 together with the diaphragm spring 14 . As a result, the frictional force between the friction surface of the clutch disc 11 and the flywheel 16 is eliminated, and a disconnected state in which the rotation of the flywheel 16 is not transmitted to the clutch disc 11 is established.

The clutch release mechanism 20 includes a clutch release fork 21, a release fork support 22 and a release cylinder 23.

The clutch release fork 21 is a member for moving the release bearing 15 in the axial direction, and is configured to be swingable while being supported by the release fork support 22 . The clutch release fork 21 is an elongated member made of metal, and has a bifurcated structure at the tip side.

As shown in FIG. 1, one end side of the clutch release fork 21 is configured with a pressing portion 21a that presses the release bearing 15 in the axial direction. The pressing portion 21a has a bifurcated structure in which the tip side thereof is bifurcated so as to sandwich the input shaft 3 inside the clutch housing 30 . A portion (contact portion) of the pressing portion 21 a that faces the release bearing 15 in the axial direction contacts the release bearing 15 . The other end side of the clutch release fork 21 is formed by a connecting portion 21 b that protrudes outside the clutch housing 30 through a through hole 31 of the clutch housing 30 and is connected to the release cylinder 23 . The other end side of the clutch release fork 21 is covered with a fork boot 32 at a position extending outside the clutch housing 30 . A fork boot 32 is attached to the through hole 31 . The fork boot 32 may be provided with a hole (cooling hole) for releasing frictional heat generated when the clutch body 10 is in the half-engaged state to the outside of the clutch housing 30 .

Further, the clutch release fork 21 has a fulcrum portion 21c supported by the release fork support 22 between the pressing portion 21a and the connecting portion 21b. The release fork support 22 is composed of a main body portion fixed to the partition wall of the clutch housing 30 and a pivot portion (not shown) having a spherical surface on the tip side of the main body portion. A partition wall of the clutch housing 30 is composed of a retainer to which a bearing (not shown) that supports the input shaft 3 is attached. A retainer is a member fixed to the clutch housing 30 . The root side of the release fork support 22 is bolted to the retainer. A boss portion 30 a of the retainer extends along the input shaft 3 inside the clutch housing 30 . The input shaft 3 is inserted inside the boss portion 30a.

The release bearing 15 is configured to be axially movable with respect to the boss portion 30a while being supported on the outer circumference of the boss portion 30a via a sleeve. The release bearing 15 is arranged so as to contact the central portion of the diaphragm spring 14 . The release bearing 15 has an outer ring supported by a sleeve on the boss portion 30 a and an inner ring that contacts the central portion of the diaphragm spring 14 . In the release bearing 15, the inner ring in contact with the diaphragm spring 14 rotates, and the outer ring in contact with the clutch release fork 21 does not rotate.

When the driver depresses the clutch pedal (not shown), the release cylinder 23 is activated. When the connection portion 21b is operated by the release cylinder 23, the clutch release fork 21 pivots about the fulcrum portion 21c. Due to this rocking, the pressing portion 21a presses the release bearing 15, and the release bearing 15 moves in the axial direction to press the central portion of the diaphragm spring 14 toward the flywheel 16, and the clutch body 10 is released. . When the clutch body 10 is released, the flywheel 16 and the clutch disc 11 are disconnected so that power cannot be transmitted. When the operating force from the release cylinder 23 is released, the pressing force acting on the release bearing 15 from the pressing portion 21a disappears, and the clutch body 10 is brought into the engaged state. When the clutch body 10 is in the engaged state, the flywheel 16 and the clutch disc 11 are connected so that power can be transmitted. Thus, the swinging motion of the clutch release fork 21 connects and disconnects the power transmission path between the crankshaft 2 on the engine side and the input shaft 3 on the transmission side.

Next, the lubrication device 100 of the first embodiment will be described. The grease supply device 100 is a device that supplies grease to the contact portion between the pressing portion 21 a of the clutch release fork 21 and the release bearing 15 . The lubrication device 100 has a second jig 120 (insertion portion 121) inserted into a guide through hole (first hole 113, second hole 114) of a first jig 110 fixed to the clutch housing 30 as will be described later. and insert the second jig 120 (insertion portion 121) until the tip portion 131 of the greasing pipe 130 provided on the second jig 120 and the relevant portion C are in a predetermined positional relationship. It is configured to be inserted toward C. As shown in FIG. 1, the relevant portion C is the clutch release fork 21 (pressing portion 21a) and the release bearing 15, which are locations requiring lubrication (locations requiring supply of grease from the tip portion 131 of the grease supply pipe 130). refers to the contact part with As shown in FIG. 1, the relevant portion C is arranged in an internal space surrounded by a clutch housing 30 (an example of the cover member of the present invention). The clutch housing 30 is formed with a jig fixing through-hole (through-hole 31 ) that communicates with the internal space.

When a vehicle equipped with the clutch device 1 is used in an environment where sand, muddy water, or the like exists, the cooling hole of the fork boot 32, the cooling hole provided in the clutch housing 30, or the opening for draining water may be damaged. Foreign matter may enter the clutch housing 30 through a hole (none of which is shown). Therefore, it is desirable to maintain the clutch release mechanism 20 and perform lubrication maintenance to additionally supply grease to the contact portion between the clutch release fork 21 and the release bearing 15 . Therefore, the lubricating apparatus 100 is configured so that the lubricating maintenance operation can be performed without removing the clutch housing 30 (or the manual transmission unit including the same) from the vehicle. This lubricating device 100 uses a lubricating pipe 130 (shown in FIG. 2, etc.) from the outside of the clutch housing 30 through a through hole 31 of the clutch housing 30 to lubricate the clutch release fork 21 and the lubricating portion. Grease is supplied to the contact portion with the release bearing 15. - 特許庁

Push the jig 110 in the arrow AR2 direction (see FIGS. 7 and 11).

The distance A1 (see FIG. 11) between the base portion 111 of the first jig 110 and the key portion 116 and the thickness B1 (see FIG. 11) of the portion of the clutch housing 30 surrounding the through hole 31 satisfy A1<B1. are set to be related. Therefore, when the first jig 110 positioned in the Y direction and the Z direction with respect to the clutch housing 30 as described above is pushed in the arrow AR2 direction (see FIGS. 7 and 11), the clutch housing 30 is penetrated. A peripheral portion of the hole 31 is inserted (press-fitted) into the space between the base portion 111 and the key portion 116 of the first jig 110 . Thereby, the first jig 110 is fixed to the clutch housing 30 .

In addition, when the portion of the clutch housing 30 surrounding the through hole 31 abuts against the bottom portion 117 between the base portion 111 and the key portion 116 of the first jig 110 , the first jig 110 is moved relative to the clutch housing 30 . are positioned with respect to the X direction.

As described above, the first jig 110 is positioned with respect to the clutch housing 30 (an example of the fixed counterpart of the present invention) in the X, Y, and Z directions, and is positioned around the clutch housing 30 (around the through hole 31). part). In other words, the first jig 110 engages the portion of the clutch housing 30 surrounding the through hole 31 while being positioned with respect to the clutch housing 30 in the X, Y and Z directions. The base portion 111 and the key portion 116 of the first jig 110 are an example of the engaging portion of the present invention.

With the first jig 110 fixed to the clutch housing 30 (the portion surrounding the through hole 31) in this manner, the first hole 113 of the first jig 110 extends toward the corresponding portion C (one pressing portion 21a). (see FIG. 9). Similarly, the second hole 114 of the first jig 110 extends toward the corresponding portion C (the other pressing portion 21a). It should be noted that the first jig 110 can be removed from the clutch housing 30 by following the procedure in reverse order.

As a step subsequent to the first step, greasing pipe 130 and second jig 120 are inserted into insertion holes (first hole 113 and second hole 114) of first jig 110 fixed to clutch housing 30 as described above. A step of inserting into (insertion step) is performed. In this insertion step, when inserting the second jig 120 into the insertion holes (the first hole 113 and the second hole 114) of the first jig 110, the step of inserting is performed in two stages. Side surfaces 121a and 121b of the insertion portion 121 of the second jig 120 are provided with marking lines, which will be described later in the second embodiment, at positions a predetermined distance from the distal end side. The insertion portion 121 has a rectangular outer peripheral shape. The side surfaces 121a and 121b are rectangular short side portions. Further, the side surface 121a is one surface in the Y direction, and the side surface 121b is the other surface in the Y direction. Furthermore, the rectangle of the insertion portion 121 is smaller than the rectangle of the opening of the first hole 113 and the rectangle of the opening of the second hole 114 .

As shown in FIG. 8, by inserting the insertion portion 121 of the second jig 120 into the first hole 113 of the first jig 110, the lubricating pipe 130 is removed from the clutch release fork 21 where lubrication is required. extends toward the pressing portion 21a. Since the pressing portion 21a has a bifurcated structure, the grease pipe 130 inserted into the first hole 113 extends toward one of the pressing portions 21a. Before oil supply pipe 130 reaches the vicinity of pressing portion 21 a of clutch release fork 21 , it may be necessary to avoid obstacles inside clutch housing 30 . For example, the obstacle includes a clip that is a component of the release bearing 15 . Since the clip is provided near the bifurcated structure of the clutch release fork 21, it is desirable that the oil supply pipe 130 does not come into contact with the pressing portion 21a.

Therefore, as a second step (first half step of the insertion step), the insertion portion 121 of the second jig 120 is inserted into the insertion hole of the first jig 110 to the position of the marking line. In the inserted state of the second step, the second jig 120 is positioned relative to the first jig 110 in the insertion hole so that the lubrication pipe 130 and the endoscope 160 can avoid obstacles in the clutch housing 30. It is operable to displace the position. That is, as the third step, a step of moving the second jig 120 so as to avoid the internal structure of the clutch housing 30 (avoidance operation step) is performed. In the following steps, the operator grasps the screen (the distal end of the grease pipe 130 and its surrounding structure ( For example, while gazing at the image including the relevant portion C), the tip portion 131 of the grease pipe 130 is held with the other hand (for example, the left hand) so as to reach the relevant portion C (see FIG. 9). 2) Perform an operation of inserting the jig 120 (insertion portion 121) toward the relevant portion C in the arrow AR3 direction (see FIGS. 9 and 11).

Regarding the third step, when the insertion portion 121 is inserted into the first hole 113, there is a clearance (about 0.5 mm) between the side surfaces 121a and 121b of the insertion portion 121 and the inner surface (inner wall) of the first hole 113. is provided. Similarly, when the insertion portion 121 is inserted into the second hole 114, a clearance (about 0.5 mm) is provided between the side surfaces 121a and 121b of the insertion portion 121 and the inner surface (inner wall) of the second hole 114. ing. Therefore, if the second jig 120 is inserted into the insertion hole up to the position of the scribe line, the greasing pipe 130 is positioned at a height where it does not come into contact with the clip of the release bearing 15 and avoids the internal structure such as the clip. , the grease pipe 130 can be positioned. In this case, it is possible to hold the stopper portion 122 side by hand and swing the distal end side of the insertion portion 121 in the Y direction.

As shown in FIG. 9, the height position of the distal end portion 131 of the grease supply pipe 130 is such that the clip of the release bearing 15 can be avoided at the height h1. In this case, the insertion of the grease pipe 130 is stopped, and the position of the tip portion 131 is controlled so as to avoid the release bearing 15 from being clipped. This height h1 also represents the insertion amount (stroke amount).

For example, in the third step, from a state in which the side surface 121b of the insertion portion 121 is in contact with the first surface 113a of the first hole 113, the lubricating pipe 130 moves to a non-contact state as an operation to avoid obstacles in the clutch housing 30. The side surface 121a of the inserting portion 121 is brought into contact with the second surface 113b of the first hole 113 that has been inserted. At this time, the second jig 120 is moved until the insertion portion 121 slides on the third surface 113c of the first hole 113 and the side surface 112a contacts the second surface 113b. This slide includes an operation of parallel movement in the Y direction and a rocking motion of swinging the tip portion 131 side to the left and right. As a result, the greasing pipe 130 is positioned so as not to contact the clip.

In this way, after the position of the grease pipe 130 is determined to avoid obstacles in the clutch housing 30, the distal end portion 131 of the grease pipe 130 is approached again toward the location requiring lubrication. do. That is, the insertion process of the second jig 120 is resumed, and the insertion portion 121 is inserted into the through hole 31 until the stopper portion 122 of the second jig 120 contacts the base portion 111 of the first jig 110 . When the stopper portion 122 of the second jig 120 is in contact with the first jig 110, the distal end portion 131 of the grease pipe 130 is inserted into the clutch housing 30 to a predetermined target position. That is, in the fourth step (the latter half of the insertion step), the insertion portion 121 is inserted deeper than the position of the scribe line, and the distal end portion 131 of the grease supply pipe 130 is inserted to the location requiring grease supply.

As shown in FIG. 9, in the fourth step, the distal end portion 131 of the oil supply pipe 130 reaches the height h2 at which one pressing portion 21a of the bifurcated structure is positioned. Thus, it is possible for the distal end portion 131 of the oil supply pipe 130 to be located near the pressing portion 21 a of the clutch release fork 21 . This height h2 is a larger insertion amount than the height h1.

Then, as a fifth step, a step of supplying grease from the opening 131a of the grease supply pipe 130 is performed. In the fifth step, the operator grasps the screen (the tip of the grease pipe 130 and the surrounding structure ( For example, while gazing at the image including the relevant portion C), the other hand (for example, the left hand) grasps the lubricator 150 and operates it (for example, the push rod 152 shown in FIG. 3 is pushed in its axial direction. The grease is supplied to the corresponding portion C (see FIG. 9) from the opening 131a of the grease supply pipe 130 by pushing the grease. In the fifth step, when an appropriate amount of grease is supplied from the grease applicator 150 connected to the grease supply pipe 130, an appropriate amount of grease is injected from the tip portion 131 of the grease supply pipe 130 to apply the grease to the pressing portion 21a. In this case, the grease supplied from the grease supply device 150 is filled in advance in the grease supply pipe 130 . Therefore, when the distal end portion 131 of the grease supply pipe 130 is fixed at a desired position, the grease supply is smoothly performed by operating the grease supply device 150 .

Then, when the greasing in the fifth step is completed, the step of removing the greasing pipe 130 is performed as the sixth step. In the sixth step, grease is removed from the tip portion 131 of the grease supply pipe 130 while the first jig 110 is attached to the through hole 31 . Thereafter, the second jig 120 is pulled out from the through hole 31 , and the tip portion 131 of the grease pipe 130 is also pulled out from the through hole 31 to the outside of the clutch housing 30 .

For example, the second jig 120 is removed from the insertion hole of the first jig 110 . When the second jig 120 is extracted from the insertion hole of the first jig 110, it can be swung left and right due to the clearance between the insertion hole and the insertion portion 121. FIG. As a result, it is possible to prevent the grease from adhering to parts or parts other than the parts requiring lubrication.

When the steps from the first step to the fifth step described above are the steps for the first hole 113, while maintaining the mounting state of the first jig 110, from the second step targeting the second hole 114 The steps up to the fifth step are performed. As a result, it is possible to supply grease to both of the pressing portions 21a having a bifurcated structure.

It should be noted that if there are no obstacles in the clutch housing 30 to reach the location requiring lubrication, the above-described second and third steps may be omitted. In this case, the scribe line of the second jig 120 is unnecessary, and the fourth step is performed following the first step to insert the insertion portion 121 of the second jig 120 into the insertion hole of the first jig 110. The insertion may be continued until the stopper portion 122 contacts the first jig 110 .

As described above, according to the lubricating apparatus 100 of the first embodiment, the pressing portion 21a of the clutch release fork 21 is lubricated without removing the clutch housing 30 (or the manual transmission unit including the same) from the vehicle. becomes possible. This facilitates lubrication maintenance work and improves workability.
10A and 10B are diagrams schematically showing modifications of the first jig 110. FIG. The first jig 110D includes a base portion 111, a projecting portion 112, and a first hole 113 for positioning. The first hole 113 is an insertion hole into which the grease pipe 130, the endoscope 160, and the second jig 120 are inserted. Here, the first hole 113 is arranged at a position shifted from the center of the first jig 110D in the Y direction. As a result, the greasing device 120 can be rotated 180 degrees after the first jig 110D is inserted, and can be applied to a different position. FIG. 10A is a schematic diagram when the first jig 110D is inserted. FIG. 10B is a schematic diagram when the first jig 110D in FIG. 10A is rotated by 180 degrees and inserted. In FIG. 10A, the first side surface 115A of the first jig 110D is the contact surface that contacts the clutch release fork 21. In FIG. 10B, the second side surface 115B of the first jig 110D contacts the clutch release fork 21. It becomes the contact surface. The grease supply pipe 130 is located outside the endoscope 160 with respect to the center in the Y direction. Note that the endoscope 160 may be positioned outside the grease pipe 130 with respect to the center in the Y direction.

(Second embodiment)
Next, an insertion amount grasping device 100A of a second embodiment will be described.

12A to 12C are schematic diagrams of the insertion amount grasping device of the second embodiment. 12A to 12C show how the second jig 120 is inserted into the first jig 110 in this order.

The insertion amount grasping device 100A continues until the distal end portion 131 of the grease supply pipe 130 reaches a position P1 (see FIG. 9) near the relevant portion C or a position P2 (see FIG. 9) a predetermined distance before the relevant portion C. 1, the required amount of insertion of the second jig 120 into the first jig 110 (hereinafter also referred to as the required amount of insertion) is visually grasped from the outside of the clutch housing 30 .

The insertion amount grasping device 100A has the same configuration as the lubricating device 100 of the first embodiment, but compared to the lubricating device 100 of the first embodiment, the insertion portion 121 of the second jig 120 has the first marking line. L1 differs in that a second marking line L2 is attached.

In the following, differences from the first embodiment will be mainly described, and the same reference numerals will be assigned to the same configurations as in the first embodiment, and description thereof will be omitted as appropriate. In the following description, the first jig 110 is positioned with respect to the clutch housing 30 in the X, Y and Z directions as described in the first embodiment. 31).

The first jig 110 and the second jig 120 may be made of resin or metal.

As shown in FIG. 12A, the second jig 120 has an insertion portion 121 inserted into a first hole 113 (or a second hole 114) formed in the first jig 110 and held by an operator. It is inserted in the direction of arrow AR4 toward portion C (see FIG. 9). As the second jig 120 is inserted toward the relevant portion C, the tip portion 131 of the grease pipe 130 eventually moves to a position P2 (see FIG. 9) a predetermined distance before the relevant portion C, and the grease pipe 130 reaches a position P1 (see FIG. 9) in the vicinity of the relevant portion C. As shown in FIG.

In this manner, the first jig 131 of the greasing pipe 130 reaches a position P2 (see FIG. 9) a predetermined distance before the relevant portion C and a position P1 (see FIG. 9) in the vicinity of the relevant portion C. In order to visually grasp the required insertion amount of the second jig 120 with respect to 110, as shown in FIG. ing. It should be noted that marks such as lines drawn with a marker or sticker may be attached to the insertion portion 121 of the second jig 120 instead of the marking lines L1 and L2.

The first scribe line L1 is drawn when the tip end portion 131 of the grease pipe 130 reaches a position P2 (see FIG. 9) which is a predetermined distance ahead of the relevant portion C (the tip end portion 131 of the grease pipe 130 and the relevant portion C becomes a predetermined positional relationship), the first marking line L1 reaches the first jig 110 (for example, the guide flange F provided on the first jig 110) (for example, the guide flange F overlapping) position (see FIG. 12B).

Therefore, the operator can visually confirm the positional relationship between the first marking line L1 and the first jig 110 (for example, the guide flange F provided on the first jig 110) from the outside of the clutch housing 30. , the required amount of insertion of the second jig 120 into the first jig 110 until the tip 131 of the grease supply pipe 130 reaches a position P2 (see FIG. 9) a predetermined distance before the relevant portion C. can be done.

The second scribe line L2 is drawn when the tip end portion 131 of the grease pipe 130 reaches a position P1 (see FIG. 9) in the vicinity of the relevant portion C (the tip end portion 131 of the grease pipe 130 and the relevant portion C are at a predetermined position). positional relationship), the position where the second marking line L2 reaches the first jig 110 (for example, the guide flange F provided on the first jig 110) (for example, overlaps the guide flange F) (see FIG. 12C).

Therefore, the operator can visually confirm the positional relationship between the second marking line L2 and the first jig 110 (for example, the guide flange F provided on the first jig 110) from the outside of the clutch housing 30. , the required amount of insertion of the second jig 120 into the first jig 110 until the tip 131 of the grease pipe 130 reaches the position P1 (see FIG. 9) in the vicinity of the relevant portion C can be grasped.

Note that the marking line L1 may be omitted.

As described above, according to the second embodiment, the tip portion 131 of the grease supply pipe 130 is located at the position P1 near the relevant portion C (see FIG. 9) or at the position P2 a predetermined distance before the relevant portion C (see FIG. 9). 9)), the required insertion amount of the second jig 120 into the first jig 110 can be visually grasped from the outside of the clutch housing 30 .

Moreover, according to the second embodiment, there are the following advantages. In other words, the required amount of insertion (stroke) for the distal end portion 131 of the oil supply pipe 130 to reach the vicinity of the relevant portion C may differ for each vehicle type (for each manual transmission unit). In this case, when the distal end portion 131 of the grease pipe 130 reaches the vicinity of the relevant portion C, the first jig 110 (for example, the first jig A mark (for example, a marking line, a line drawn with a marker or a sticker) to reach the guide flange F) provided on the second jig 110 is attached to the insertion portion 121 of the second jig 120 . As a result, a single first jig 110 can be used to lubricate a plurality of vehicle types (a plurality of manual transmission units) that require different insertion amounts. That is, since it is not necessary to prepare the first jig 110 for each vehicle type (for each manual transmission unit), the increase in the types of the first jig 110 and the associated increase in investment (cost) can be suppressed. can do.

(Third embodiment)
Next, an insertion amount grasping device 100B of a third embodiment will be described.

13A and 13B are schematic diagrams of the insertion amount grasping device of the third embodiment. 13A and 13B show how the second jig 120 is inserted into the first jig 110 in this order.

It is a device for grasping the relationship) not visually but by hand feeling (feeling of the hand holding the second jig 120).

The insertion amount grasping device 100B has the same configuration as the lubricating device 100 of the first embodiment, but compared to the lubricating device 100 of the first embodiment, the insertion portion 121 of the second jig 120 has the first projection portion. The difference is that p1a and p1b are provided.

In the following, differences from the first embodiment will be mainly described, and the same reference numerals will be assigned to the same configurations as in the first embodiment, and description thereof will be omitted as appropriate. In the following description, the first jig 110 is positioned with respect to the clutch housing 30 in the X, Y and Z directions as described in the first embodiment. 31).

At least one of the first jig 110 and the second jig 120 is made of resin. When one is made of resin, the other may be made of resin or metal.

As shown in FIG. 13A, the second jig 120 has an insertion portion 121 inserted into a first hole 113 (or a second hole 114) formed in the first jig 110, and is held by an operator. It is inserted in the direction of arrow AR5 toward portion C (see FIG. 9). As the second jig 120 is inserted toward the relevant portion C, the tip portion 131 of the grease supply pipe 130 eventually reaches a position P1 near the relevant portion C (see FIG. 9).

In this way, the tip portion 131 of the grease pipe 130 reaches the position P1 (see FIG. 9) in the vicinity of the relevant portion C (the tip portion 131 of the grease pipe 130 and the relevant portion C are in a predetermined positional relationship). ) can be grasped by hand (feeling of the hand holding the second jig 120) rather than visually, the insertion portion 121 of the second jig 120 is provided with the first protrusions p1a and p1b.

The first protrusions p1a and p1b are, for example, hemispherical protrusions. The first protrusions p1a and p1b are not limited to the hemispherical shape, and may be protrusions of other shapes.

As the second jig 120 is inserted toward the relevant portion C, the tip portion 131 of the grease supply pipe 130 reaches the position P1 (see FIG. 9) near the relevant portion C of the first projections p1a and p1b. is inserted into the first hole 113 (or the second hole 114) (see FIG. 13B) and provided at a position where friction (frictional force) is generated between the first hole 113 (or the second hole 114) It is

In order to generate this friction, as shown in FIG. The thickness B2 (design dimension) of 121 is set so as to satisfy the relationship of A2<B2.

Friction) can be grasped by hand feeling (the feeling of the hand holding the second jig 120) instead of visually.

As described above, according to the third embodiment, the distal end portion 131 of the grease pipe 130 reaches the position P1 (see FIG. 9) in the vicinity of the relevant portion C (the distal end portion 131 of the grease pipe 130 and the corresponding position P1). A predetermined positional relationship with the portion C) can be grasped not by sight but by hand feeling (the feeling of the hand holding the second jig 120).

This is when the distal end portion 131 of the grease pipe 130 reaches a position P1 (see FIG. 9) near the relevant portion C (see FIG. 9) in accordance with the operation of inserting the second jig 120 toward the relevant portion C (greasing pipe 130 is inserted into the first hole 113 (or second hole 114) (see FIG. 13B), and the first hole 113 (or second 2 holes 114) to generate friction (frictional force).

Therefore, the operator can see the screen displayed on the display unit 163 attached to the operation unit 162 held with one hand (for example, the right hand) (the tip of the grease supply pipe 130 and the surrounding structure (for example, the relevant portion)). C)), the tip 131 of the grease supply pipe 130 is held with the other hand (for example, the left hand) so as to reach the position P1 (see FIG. 9) near the relevant portion C). 2. The user can concentrate on the operation of inserting the jig 120 (insertion portion 121) toward the relevant portion C in the arrow AR5 direction.

Moreover, according to the third embodiment, there are the following advantages. That is, as described above, when the first protrusions p1a and p1b are inserted into the first hole 113 (or the second hole 114), the first protrusions p1a and p1b and the first hole 113 (or the second hole 113) The friction between the second jig 120 and the inner wall of the hole 114) causes the second jig 120 to be fixed to the first jig 110. FIG. Further, the gap (clearance) between the insertion portion 121 of the second jig 120 inserted into the first hole 113 (or the second hole 114) and the inner wall of the first hole 113 (or the second hole 114) is 0. 0.5 mm.

Therefore, when the above friction occurs, even if the operator releases the second jig 120, the position of the distal end portion 131 of the grease supply pipe 130 relative to the relevant portion C does not change (almost does not change).

Therefore, when the above-described friction occurs, that is, when the tip end portion 131 of the grease supply pipe 130 reaches the position P1 (see FIG. 9) near the relevant portion C, the other side gripping the second jig 120 until then Release the hand (for example, the left hand) and use the free other hand (for example, the left hand) to newly grasp and operate the lubricator 150 (for example, push the push rod 152 shown in FIG. 3 in its axial direction The grease can be supplied to the corresponding portion C from the opening portion 131a of the grease supply pipe 130 by pressing. That is, a single operator can perform the operation of inserting the second jig 120 toward the relevant portion C, followed by the operation of supplying grease to the relevant portion C from the opening 131a of the grease supply pipe 130. . This improves work efficiency.

The insertion amount grasping device 100C has the same configuration as the insertion amount grasping device 100 of the first embodiment, but compared to the insertion amount grasping device 100 of the first embodiment, the insertion portion 121 of the second jig 120 has the first Second protrusions p2a (p2a 1 , p2a ₂ , p2a ₃ ) on the inner wall of the first hole 113 (and the second hole 114) formed in the first jig 110 and the point where the protrusions _{p1a and} p1b are provided. , p2b (p2b ₁ , p2b ₂ , p2b ₃ ) are provided.

In the following, differences from the first embodiment will be mainly described, and the same reference numerals will be assigned to the same configurations as in the first embodiment, and description thereof will be omitted as appropriate. In the following description, the first jig 110 is positioned with respect to the clutch housing 30 in the X, Y and Z directions as described in the first embodiment. 31).

At least one of the first jig 110 and the second jig 120 is made of resin. When one is made of resin, the other may be made of resin or metal.

As shown in FIG.

In this manner, the tip portion 131 of the grease pipe 130 is at a position P2 (see FIG. 9) a predetermined distance before the relevant portion C, and the tip portion 131 of the grease pipe 130 is at a position P1 (see FIG. 9) near the relevant portion C. In order to grasp the arrival (the predetermined positional relationship between the tip portion 131 of the grease supply pipe 130 and the relevant portion C) by hand feeling (the feeling of the hand holding the second jig 120) instead of visually. , the insertion portion 121 of the second jig 120 is provided with the first protrusions p1a and p1b. Second projections p2a (p2a 1 , p2a ₂ , p2a ₃ ), p2b (p2b ₁ , p2b _{2 ,} p2b) are formed on the inner wall of the first hole 113 (and the second hole 114) formed in the first jig 110. ₃ ) is provided.

The first protrusions p1a, p1b, the second protrusions p2a (p2a ₁ , p2a ₂ , p2a ₃ ), and p2b (p2b ₁ , p2b ₂ , p2b ₃ ) are hemispherical protrusions, for example. In addition, the first protrusions p1a and p1b, the second protrusions p2a (p2a ₁ , p2a ₂ , p2a ₃ ) and p2b (p2b ₁ , p2b ₂ , p2b ₃ ) are not limited to hemispherical shapes, and protrusions of other shapes may be a part.

The first protrusions p1a and p1b are positioned at a position P2 where the distal end portion 131 of the grease supply pipe 130 is a predetermined distance from the relevant portion C (see FIG. 9) as the second jig 120 is inserted toward the relevant portion C. , is provided at a position where it is inserted into the first hole 113 (or the second hole 114) when the distal end portion 131 of the grease supply pipe 130 reaches the position P1 (see FIG. 9) near the relevant portion C ( 14B and 14C).

In other words, the required amount of insertion (stroke) for the distal end portion 131 of the oil supply pipe 130 to reach the vicinity of the relevant portion C may differ for each vehicle type (for each manual transmission unit). In this case, for each vehicle type (for each manual transmission unit) that requires a different amount of insertion, when the tip portion 131 of the grease supply pipe 130 reaches the vicinity of the corresponding portion C, the second Projections p2a (p2a ₁ , p2a ₂ , p2a ₃ ) and p2b (p2b ₁ , p2b ₂ , p2b ₃ ) are arranged. As a result, a single first jig 110 can be used to lubricate a plurality of vehicle types (a plurality of manual transmission units) that require different insertion amounts. That is, since it is not necessary to prepare the first jig 110 for each vehicle type (for each manual transmission unit), the increase in the types of the first jig 110 and the associated increase in investment (cost) can be suppressed. can do.
