  However, conventionally, this type of clutch disk wear detection device has different indicator lengths and attachment positions depending on the clutch and transmission specifications.

  For this reason, an indicator having a different length is required for each vehicle specification, which increases the man-hours for managing the parts, and in some cases, the production cost of the indicator is high in a vehicle type with a small number of production.

  The present invention has been devised in view of such circumstances, and an object of the present invention is to provide a clutch disk wear detection device capable of reducing the types of indicators.

  In order to achieve such an object, the present invention provides a clutch disk wear detecting device in which an indicator is attached to a clutch housing via a stay, and a slide base is fixed to the stay, and the indicator is attached to the slide base. The slide pedestal that is attached is movably mounted, the indicator is configured to be movable along the slide base via the slide pedestal, and a stopper that restricts the movement of the slide pedestal is provided on the slide pedestal. Features.

  Since the indicator of the present invention is a slide adjustment type, the types of indicators having different lengths can be reduced, so that troublesome part management is not required, and the current layout can be used without change.

1 is an overall perspective view of a clutch disk wear detection device according to an embodiment of the present invention. It is a whole perspective view of the indicator with which the slide base was equipped. It is a disassembled perspective view of a slide base, a slide base, and an indicator. It is explanatory drawing of the indicator which can adjust length. It is a side view of the conventional clutch disk wear detection apparatus.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  1 to 4 show an embodiment of a clutch disk wear detecting device according to the present invention. In FIG. 1, reference numeral 25 denotes a clutch operating shaft 29 inserted through the clutch housing 27 so as to be swingable around a rotation center. An outer lever (release shaft lever) is rotatably connected to the end of the outer lever 25 via a push rod 33 and a ball joint 35 of the clutch booster 31. An indicator plate 37 as a pointer is attached to the end of the push rod 33, and an indicator (wear indicator) 39 is attached to the clutch housing 27 side correspondingly.

  As shown in FIGS. 2 to 4, the indicator 39 is formed of a single metal plate member formed in a strip shape, and a scale indicating the state when the clutch disk is assembled at the front end side thereof (an imprint of “SET” or the like) ) 41 is provided, and on the side fixed to a slide pedestal (stand) 43, which will be described later, a scale (marked “MIN”) 45 indicating a worn state of the clutch disk is provided. Furthermore, V-shaped notches 47 and 49 are provided in the plate width portion of the indicator 39 corresponding to the two scales 41 and 45. And the pin coupling hole 51 is formed in the rear-end part of the indicator 39, and the pin 53 protrudingly provided by the slide base 43 side to the said pin coupling hole 51 can be press-fit.

  As shown in FIG. 3, the slide pedestal 43 is formed of a thin plate member having a rectangular shape in plan view, and a concave positioning step 55 along the rear end side shape of the indicator 39 is formed on the upper surface thereof. The pin 53 is provided in a protruding manner. When the rear end side of the indicator 39 is set on the positioning step portion 55 and the pin 53 is press-fitted into the pin coupling hole 51, the indicator 39 is detachably connected to the slide base 43 in a straight line.

  In FIG. 3, reference numeral 57 denotes a slide base (case) having an approximately U-shaped cross section that opens upward. On the upper sides of the left and right side walls 59 and 61, drop-off prevention pieces are bent inward. 63 and 65 are formed. As shown in FIG. 4, the slide base 43 is mounted in the slide base 57 so as to be movable in the front-rear direction of the slide base 57 (in the direction of the arrow in the figure). Thus, the slide base 43 is prevented from falling off from the upper part of the slide base 57.

  Furthermore, as shown in FIG. 3, a screw hole 67 is provided in the thick part of the slide base 43 behind the positioning step 55, and a dial stopper 69 as a screw member is screwed into the screw hole 67 from above. . When the dial stopper 69 is screwed and the tip of the shaft portion is brought into pressure contact with the bottom of the slide base 57, the slidable slide base 43 is fixed to the slide base 57 at an arbitrary position.

  2 and 3, reference numerals 71 and 73 denote bolts and washers for fixing the slide base 57 to the clutch housing 27 via the stay 75, and 77 denotes a bolt insertion hole provided in the slide base 57. The slide base 57 is fixed to the stay 75 via 71, a washer 73 and a nut (not shown), and the slide base 57 is fixed to the clutch housing 27 via the stay 75.

  Since the clutch disk wear detecting device 79 according to the present embodiment is configured as described above, the indicator 39 is moved to the slide base by loosening the dial stopper 69 and moving the slide base 43 in the direction of the arrow as shown in FIG. 43 and move in the direction of the arrow. When the dial stopper 69 is tightened after the movement, the indicator 39 is fixed at an arbitrary position together with the slide base 43, and the length of the indicator 39 can be adjusted over the dimension L as shown in FIG.

  Therefore, when the clutch disk is assembled, the slide base 57 may be fixed to the clutch housing 27 with the stay 57 so as to correspond to the indicator plate 37 as shown in FIG.

  Then, the slide base 43 to which the indicator 39 is pinned is mounted on the slide base 57, and the dial stopper 69 is loosened so that the tip of the indicator plate 37 points to the notch 47 of the scale 41 that is “SET”. After adjusting the position, the dial stopper 69 may be tightened to fix the slide base 43 to the slide base 57.

  Thus, as the clutch disk wears, the outer lever 25 rotates in the direction of arrow A in FIG. 1, and the indicator plate 37 moves in the same direction. When the clutch disk reaches the wear limit, the wear limit of the clutch disk is recognized by pointing to the notch 49 of the scale 45 whose tip of the indicator plate 37 is “MIN”.

  Further, as described above, conventionally, the length of the indicator differs depending on the specifications of the clutch and transmission, and the mounting position is different, so that an indicator having a different length for each vehicle specification has been required.

  However, since the indicator 39 of the present embodiment is a slide adjustment type, in any specification, after the slide base 57 is fixed to each clutch housing with the stay 57 corresponding to the indicator plate, the indicator 39 is pinned. Attach the combined slide base 43 to the slide base 57 and adjust the position of the indicator 39 by loosening the dial stopper 69 so that the tip of the indicator plate points to the notch 47 of the scale 41 with “SET”. Thereafter, the dial stopper 69 may be tightened to fix the slide base 43 to the slide base 57.

  In addition, since the indicator 39 is detachably attached to the slide base 43, the indicator can be easily exchanged according to the specifications. However, since the indicator of the present embodiment is a slide adjustment type, the number of indicators to be exchanged compared to the conventional one Is deleted.

  As described above, according to the present embodiment, the types of indicators having different lengths can be reduced, so that troublesome component management is not required, and the current layout can be used without being changed.

  In addition, the present embodiment has an advantage that the length of the indicator can be easily adjusted by a simple operation of tightening / loosening the dial stopper 69 and the manufacturing cost of the clutch disk wear detecting device can be suppressed.
