Description

  The present invention relates to an operation device that transmits an operation stroke of an operation member to an operation target means as a movement stroke of an operation rod.

  For example, in a brake device for a vehicle, the stepping stroke when the driver depresses the brake pedal is boosted by a booster as a stepping force, and then a hydraulic pressure corresponding to the stepping force is applied by a master cylinder to operate a wheel cylinder. Thus, a desired braking force is generated.

  The pedal device used in this brake device is generally configured such that the upper end portion of the brake pedal is rotatably supported on the vehicle body side, and this brake pedal is biased and supported by a spring in a direction opposite to the stepping direction by the driver. The operation rod connected to the brake booster is connected to the middle part of the brake pedal.

  By the way, when operating such a brake device, it is desirable that the operation feeling changes according to the depression amount of the brake pedal. For example, in the brake operating device described in Patent Document 1 below, a damper and a spring unit are interposed between the push rod of the brake pedal and the input rod of the vacuum booster, and the spring force can be varied according to the running state of the vehicle. Thus, the feeling of stepping can be increased and a stable operation feeling can be obtained during high speed traveling, and the stepping operation can be obtained without fatigue by reducing the feeling of stepping during low speed traveling.

JP 05-262210 A

By the way, as a brake operation device having a good operation feeling, the following brake operation characteristics are required.
1. Smooth brake pedal operating characteristics when the brake pedal is depressed by setting the initial friction to a small value.
2. Operational characteristics that are easy to control from when the brake pedal is depressed until it is held by ensuring a sense of rigidity in the middle of operation.
3. Stable operating characteristics when holding the brake pedal by ensuring the pedaling hysteresis.

  However, in the conventional brake operating device described above, the brake pedal is biased and supported by a return spring to reduce the rattling of the brake pedal, so the friction at the initial stage of operation becomes large and smooth. It is difficult to define the operating characteristics of the brake pedal. In addition, since the rigidity of the hydraulic cylinder that operates the brake caliper in the brake device is constant, it is difficult to ensure the rigidity of the brake pedal operation in the middle of the operation. Further, since the brake operation reaction force is applied by the return spring, it is difficult to ensure the pedaling force hysteresis. In addition, although the brake operation device described in the following Patent Document 1 makes the operation reaction force variable according to the traveling state of the vehicle, not only cannot the above-mentioned operation characteristics be ensured, but also the device becomes complicated and large.

FIG. 3 is a graph showing a change in pedal stroke with respect to the pedal effort in the brake operation device of the first embodiment.

  In the brake operating device according to the first embodiment, as shown in FIGS. 1 and 2, the brake pedal 11 as an operating member is supported by a support shaft 13 so that the upper end of the brake pedal 11 is rotatably suspended by a mounting bracket 12 on the vehicle body side. A pedal 14 that can be depressed by the occupant is mounted at the lower end. On the other hand, the operating rod 15 has a tip connected to a master cylinder and a brake booster (not shown) as operation target means for operating and controlling the brake device.

  Further, the operating rod 15 has a threaded portion 15a formed at the base end, and this threaded portion 15a is screwed to the clevis 16, and the lock nut 17 is screwed to the operating rod 15 and contacts the clevis 16. Thus, the loosening of the screwed state of the operation rod 15 (screw portion 15a) with respect to the clevis 16 is prevented. The clevis 16 has bifurcated portions 16a and 16b. The bifurcated portions 16a and 16b are positioned on both sides of the intermediate portion of the brake pedal 11 with a predetermined interval, and the connecting shaft 18 has the brake pedal 11 and the bifurcated portion 16a. , 16b are connected to each other so as to be freely rotatable. Further, a return spring 19 is engaged with one end of the connecting shaft 18, and the brake pedal 11 is urged and supported in the returning direction, that is, counterclockwise in FIG.

  Therefore, when the occupant steps on the brake pedal 11, the brake pedal 11 rotates via the support shaft 13, and the operation stroke (stepping force) is transmitted as a movement stroke to the operation rod 15 via the connecting shaft 18 and the clevis 16. As a result, the operating rod 15 moves in the axial direction, and the brake booster and the master cylinder can be operated.

  In this embodiment, the connecting member of the present invention for connecting the brake pedal 11 and the operating rod 15 is constituted by a connecting shaft 18.

  In the brake operating device according to the present embodiment, a stroke changing member that can change the moving stroke of the operating rod 15 relative to the operating stroke of the brake pedal 11 is interposed between the connecting shaft 18 and the operating rod 15. . In the present embodiment, a frictional force imparting member to which a frictional force acts according to the operation of the brake pedal 11 is interposed between the brake pedal 11 and the connecting shaft 18.

  That is, the connecting shaft 18 has the collar 21 fitted to the outer peripheral portion at the intermediate position in the axial direction. The collar 21 has a cylindrical shape, and a groove portion 21a is formed on the outer peripheral surface along the circumferential direction. A rubber O-ring 22 is attached to the groove portion 21a. On the other hand, the brake pedal 11 has a connecting hole 11a formed at an intermediate position in the longitudinal direction, and the collar 21 of the connecting shaft 18 is fitted into the connecting hole 11a via an O-ring 22. In this case, a collar 21 is interposed between the brake pedal 11 and the connecting shaft 18, an O-ring 22 is interposed between the collar 21 and the brake pedal 11, and the outer peripheral surface of the collar 21 and the connecting hole are connected. A predetermined gap is provided between the inner peripheral surface of 11a and the O-ring 22 can be deformed by the amount of the gap.

  In addition, the connecting shaft 18 is fitted with collars 25 and 26 via metal bushes 23 and 24 at respective end portions in the axial direction, that is, outer peripheral portions on both sides of the collar 21. The collars 25 and 26 have a cylindrical shape, and groove portions 25a and 26a are formed on the outer peripheral surface along the circumferential direction. Rubber O-rings 27 and 28 are attached to the groove portions 25a and 26a. On the other hand, the bifurcated portions 16a and 16b of the clevis 16 are formed with connecting holes 16c and 16d at their respective ends. The collars 25 and 26 of the connecting shaft 18 are O-rings 27 and 28 in the connecting holes 16c and 16d. Is fitted through. In this case, collars 25 and 26 are interposed between the bifurcated portions 16a and 16b of the clevis 16 and the connecting shaft 18, and O-rings 27 and 28 are interposed between the collars 25 and 26 and the bifurcated portions 16a and 16b. In addition, a predetermined gap is provided between the outer peripheral surface of the collars 25 and 26 and the inner peripheral surface of the coupling holes 16c and 16d, and the O-rings 27 and 28 can be deformed by the amount of the gap. ing.

  In this embodiment, the stroke changing member of the present invention is a first elastic member and is composed of O-rings 22, 27, 28. Further, the load transmission element of the present invention is constituted by the collars 21, 25 and 26.

  Further, the collars 25 and 26 described above are integrally formed with flange portions 25b and 26b facing the side surfaces of the brake pedal 11, and the end surfaces of the flange portions 25b and 26b facing the brake pedal 11 are along the circumferential direction. Groove portions 25c and 26c are formed, and rubber O-rings 29 and 30 are mounted in the groove portions 25c and 26c. The O-rings 29 and 30 supported by the collars 25 and 26 are respectively crimped to the side surfaces of the brake pedal 11. In addition, auxiliary rings 31 and 32 each having a ring shape are mounted on the outer peripheral portions of the collars 25 and 26 between the collar portions 25b and 26b and the bifurcated portions 16a and 16b of the clevis 16 so that the brake pedal The crimping of the O-rings 29 and 30 to the 11 side surfaces is held.

  In this case, collars 25 and 26 are interposed between the bifurcated portions 16 a and 16 b of the clevis 16 and the connecting shaft 18, and O-rings 29 and 30 are interposed between the collars 25 and 26 and the brake pedal 11. In addition, a predetermined gap is provided between the end faces of the collars 25 and 26 and the side face of the brake pedal 11, and the O-rings 27 and 28 can be deformed by the amount of the gap. Further, the O-rings 29 and 30 are pressure-bonded to the side surface of the brake pedal 11, and are deformed along with the turning operation of the brake pedal 11, thereby increasing the acting frictional force.

  In the present embodiment, the frictional force applying member of the present invention is a second elastic member, and is constituted by O-rings 29 and 30, and the auxiliary rings 31 and 32 also function as the frictional force applying members. . Further, the load transmission element of the present invention is constituted by the collars 25 and 26.

  Therefore, when the occupant steps on the brake pedal 11, the brake pedal 11 is rotated in the clockwise direction in FIG. Then, the operation stroke (depression force) of the brake pedal 11 is transmitted as a movement stroke from the brake pedal 11 to the clevis 16 via the connecting shaft 18, and this movement stroke is further transmitted from the clevis 16 to the operation rod 15. The rod 15 moves forward.

  At this time, the O-ring 22 is deformed along with the movement of the brake pedal 11, so that the inner peripheral surface of the connecting hole 11 a of the brake pedal 11 contacts the outer peripheral surface of the collar 21 and is fitted to the connecting shaft 18. As the O-rings 27 and 28 are deformed as the movements 25 and 26 move, the outer peripheral surfaces of the collars 25 and 26 come into contact with the inner peripheral surfaces of the connecting holes 16 c and 16 d of the clevis 16. Therefore, shakiness in the axial direction and radial direction of the connecting shaft 18 is suppressed among the brake pedal 11, the connecting shaft 18 and the clevis 16, and a predetermined rigidity is ensured when the brake pedal 11 is operated and held. Is done.

  The operation stroke generated by depressing the brake pedal 11 is partially absorbed by the deformation of the O-rings 22, 27, 28, and the movement stroke transmitted to the clevis 16 is changed (decreased). ) In this case, since the stroke is absorbed by crushing the O-rings 22, 27, 28, the amount of absorption of this stroke is large at the initial stage of depression of the brake pedal 11, and gradually decreases. 21 and disappears when the collars 25 and 26 contact the clevis 16.

  On the other hand, the O-rings 29 and 30 are deformed when the brake pedal 11 is depressed, and the frictional force between the O-rings 29 and 30 and the side surface of the brake pedal 11 is increased, while the O-rings 29 and 30 are returned when the brake pedal 11 is returned. After the deformation is released, the O-rings 29 and 30 are deformed, and the frictional force with the side surface of the brake pedal 11 is increased, thereby generating hysteresis.

That is, in the conventional brake operation device, when the brake pedal 11 is stepped on, as shown by a one-dot chain line in FIG. 3, the pedal stroke SP increases because the rattling is absorbed up to the idle position SP _{0 in the} initial step. The pedaling force FP does not increase. If the brake pedal 11 is further depressed, the pedal effort FP increases with an increase in the pedal stroke SP. At this time, the pedal effort FP increases linearly as the pedal stroke SP increases.

On the other hand, in the brake operating device of the present embodiment, as shown by the solid line in FIG. 3, when the brake pedal 11 is depressed, the pedal effort FP increases as the pedal stroke SP increases. At this time, as the pedal stroke SP increases, the pedal effort FP increases in a curve. That is, as the pedal stroke SP increases, the pedaling force FP is absorbed (absorbed amount SP _k ) by the above-described O-rings 22, 27, 28 between FP ₁ and FP _2. If the absorption by the O-rings 22, 27, and 28 becomes impossible, the number increases linearly.

  When the brake pedal 11 is depressed, the O-rings 29 and 30 are deformed to one side, and a frictional force is generated between the O-rings 29 and 30 and the brake pedal 11. On the other hand, when the brake pedal 11 is returned, the deformation of the O-rings 29, 30 to one side is released, and then the O-rings 29, 30 are deformed to the other side, between the O-rings 29, 30 and the brake pedal 11. Since a frictional force is generated, pedaling force hysteresis dF is generated here.

  Thus, in the brake operating device of the first embodiment, the brake pedal 11 and the clevis 16 connected to the operating rod 15 are connected by the connecting shaft 18, and the operating stroke of the brake pedal 11 is changed to the clevis 16 and the operating rod 15. An O-ring 27 as a stroke changing member that can change the movement stroke of the operation rod 15 relative to the operation stroke of the brake pedal 11 between the connecting shaft 18 and the clevis 16. 28 is interposed.

  Therefore, when the brake pedal 11 is depressed, the operation stroke of the brake pedal 11 is absorbed by the O-rings 27 and 28 and is transmitted to the operation rod 15 via the clevis 16 as a movement stroke. Accordingly, the movement stroke is reduced, and the feeling of operation of the brake pedal 11 by the occupant can be improved.

  That is, as the O-rings 27 and 28 are deformed by the collars 25 and 26 fitted to the connecting shaft 18 as the brake pedal 11 moves, the stroke (stepping force) is absorbed. Further, it is possible to suppress the shakiness of the connecting shaft 18 between the connecting shaft 18 and the clevis 16 in the axial direction and the radial direction, and to ensure a predetermined rigidity when the brake pedal 11 is operated and held. Can do. Then, with respect to the operation stroke generated by depressing the brake pedal 11, the movement stroke (stepping force) transmitted to the operation rod 15 increases in a quadratic curve. That is, when the depression amount of the brake pedal 11 is small, the stroke absorption amount becomes large and the sensitivity becomes bad. When the depression amount of the brake pedal 11 becomes large, the stroke absorption amount becomes small and the sensitivity becomes good. The operation feeling of the pedal 11 is improved.

  In this embodiment, an O-ring 22 serving as a stroke changing member is provided between the brake pedal 11 and the connecting shaft 18 so that the moving stroke of the operating rod 15 with respect to the operating stroke of the brake pedal 11 can be changed. Yes. Therefore, the operation stroke of the brake pedal 11 is absorbed not only by the O-rings 27 and 28 but also by the O-ring 22, and the stroke absorption amount can be ensured appropriately.

  In this case, the stroke changing member is the first elastic member and is constituted by the O-rings 22, 27, 28, and not only the rotation direction of the brake pedal 11 but also the rattling in the direction crossing the rotation direction. Can be absorbed. Then, collars 25 and 26 as load transmitters are mounted on the outer peripheral portion of the connecting shaft 18, and O between the collars 25 and 26 and the connecting holes 16 c and 16 d formed in the bifurcated portions 16 a and 16 b of the clevis 16. Rings 27 and 28 are interposed. Therefore, the apparatus can be made compact and the mountability on the vehicle can be improved.

  Further, between the brake pedal 11 and the connecting shaft 18, O-rings 29 and 30 are interposed as frictional force applying members to which a frictional force is applied according to the operation of the brake pedal 11. Accordingly, the O-rings 29 and 30 are deformed to one side when the brake pedal 11 is depressed, and a frictional force is generated between the brake pedal 11 and the O-rings 29 and 30 to one side when the brake pedal 11 is returned. Since the deformation is released to the other side and a frictional force is generated with the brake pedal 11, a pedaling force hysteresis is generated here. Therefore, a predetermined rigidity when the brake pedal 11 is operated and held can be ensured by the generated frictional force, and the feeling of operation of the brake pedal 11 by the occupant can be improved.

  Further, the frictional force applying member is a second elastic member and is configured by O-rings 29 and 30, and rattling of the brake pedal 11 and the like can also be absorbed by the O-rings 29 and 30. Then, collars 25 and 26 as load transmitters are mounted on the outer periphery of the connecting shaft 18, and O-rings 29 and 30 are interposed between the collars 25 and 26 and the brake pedal 11. Therefore, the apparatus can be made compact and the mountability on the vehicle can be improved.

Thus, the acting frictional force increases.

  In this case, the protrusions 46 d and 47 d of the rubber bushes 46 and 47 apply a frictional force by being pressed against the side surface of the brake pedal 11, and the inclined portions 46 a by the collars 44 and 45 as the brake pedal 11 is rotated. , 47a is deformed to increase the frictional force. In this embodiment, a frictional force limiting mechanism for limiting the increase of the frictional force is provided. That is, in the rubber bushes 46 and 47, the inclined portions 46a and 47a are deformed to the operation side by the collars 44 and 45 in accordance with the turning operation of the brake pedal 11, so that the protruding portions 46d and 47d are formed on the side surface of the brake pedal 11. Although the frictional force to be crimped increases, the protrusions 46b and 47b are engaged with the collars 44a and 45a constituting the frictional force limiting mechanism integrated with the collars 44 and 45, so that the brake pedal 11 is deformed to the side surface side. The amount is limited.

  In this embodiment, the stroke changing member of the present invention is a first elastic member and is constituted by rubber bushes 46 and 47, and the load transmitting element of the present invention is constituted by collars 44 and 45. The frictional force imparting member of the present invention is a second elastic member, and is similarly composed of rubber bushes 46 and 47, and the load transmitting element of the present invention is composed of collars 44 and 45.

  Accordingly, when the occupant steps on the brake pedal 11, the brake pedal 11 is rotated forward by the depression force. Then, the operation stroke (depression force) of the brake pedal 11 is transmitted as a movement stroke from the brake pedal 11 to the clevis 16 via the connecting shaft 18, and this movement stroke is further transmitted from the clevis 16 to the operation rod 15. The rod 15 moves forward.

  At this time, with the movement of the brake pedal 11, the collars 44 and 45 fitted to the connecting shaft 18 press the rubber bushes 46 and 47, so that the rubber bushes 46 and 47 are deformed, and the collars 44 and 45. The outer peripheral surface is in contact with the inner peripheral surfaces of the connecting holes 16c and 16d of the clevis 16. Therefore, shakiness in the axial direction and radial direction of the connecting shaft 18 is suppressed among the brake pedal 11, the connecting shaft 18 and the clevis 16, and a predetermined rigidity is ensured when the brake pedal 11 is operated and held. Is done.

  In addition, the operation stroke generated by depressing the brake pedal 11 is partially absorbed by the deformation of the rubber bushes 46 and 47, and the movement stroke transmitted to the clevis 16 is changed (reduced). The In this case, since the rubber bushes 46 and 47 are crushed to absorb the stroke, the amount of absorption of this stroke is large at the beginning of the depression of the brake pedal 11 and gradually decreases, and the collars 44 and 45 are connected to the clevis 16. When the contact holes 16c and 16d are not contacted, they disappear. Therefore, as the operation stroke by the brake pedal 11 increases, the movement stroke (stepping force) transmitted to the operation rod 15 is absorbed by the rubber bushes 46 and 47 for a predetermined period, and thus increases in a curve. It will be.

  On the other hand, the rubber bushes 46 and 47 are deformed forward when the brake pedal 11 is depressed, and the frictional force between the protrusions 46d and 47d and the side surface of the brake pedal 11 is increased, while the rubber bush 46 is returned when the brake pedal 11 is returned. , 47 is released, the frictional force between the rubber bushes 46, 47 and the side surface of the brake pedal 11 becomes constant, and hysteresis is generated here. In addition, since the amount of deformation of the rubber bushes 46 and 47 toward the brake pedal 11 is limited by the flange portions 44a and 45a, a great increase in frictional force is prevented. When the brake pedal 11 is stepped on, the rubber bushes 46 and 47 are deformed only by the gaps in front of the collars 44 and 45 and the connecting holes 16c and 16d of the clevis 16, so that the rubber bushes 46 and 47 are used for the brake pedal 11. The pressing force, that is, the frictional force increases. On the other hand, when the brake pedal 11 is returned, the deformation of the rubber bushes 46 and 47 is released, so that there is no gap behind the collars 44 and 45 and the connecting holes 16c and 16d of the clevis 16. 47 is not deformed, and the pressing force to the brake pedal 11, that is, the frictional force is constant.

  Thus, in the brake operating device of the second embodiment, the brake pedal 11 and the clevis 16 connected to the operating rod 15 are connected by the connecting shaft 18, and the operating stroke of the brake pedal 11 is changed to the clevis 16 and the operating rod 15. A rubber bush 46 serving as a stroke changing member that can change the movement stroke of the operation rod 15 with respect to the operation stroke of the brake pedal 11 between the connecting shaft 18 and the clevis 16. 47 is interposed.

  Accordingly, when the brake pedal 11 is depressed, the operation stroke of the brake pedal 11 is absorbed by the rubber bushes 46 and 47 and is transmitted to the operation rod 15 via the clevis 16 as a movement stroke. Accordingly, the movement stroke is reduced, and the feeling of operation of the brake pedal 11 by the occupant can be improved.

  That is, since the rubber bushes 46 and 47 are deformed by the collars 44 and 45 fitted to the connecting shaft 18 as the brake pedal 11 moves, the stroke (stepping force) is absorbed. Further, it is possible to suppress the shakiness of the connecting shaft 18 between the connecting shaft 18 and the clevis 16 in the axial direction and the radial direction, and to ensure a predetermined rigidity when the brake pedal 11 is operated and held. Can do. Then, with respect to the operation stroke generated by depressing the brake pedal 11, the movement stroke (stepping force) transmitted to the operation rod 15 increases in a quadratic curve. That is, when the depression amount of the brake pedal 11 is small, the stroke absorption amount becomes large and the sensitivity becomes bad. When the depression amount of the brake pedal 11 becomes large, the stroke absorption amount becomes small and the sensitivity becomes good. The operation feeling of the pedal 11 is improved.

  Further, rubber bushes 46 and 47 as frictional force imparting members that are subjected to a frictional force according to the operation of the brake pedal 11 are interposed between the brake pedal 11, the connecting shaft 18 and the clevis 16. Accordingly, the rubber bushes 46 and 47 are deformed by the brake pedal 11 when the brake pedal 11 is depressed, and the frictional force generated between the brake pedal 11 and the brake pedal 11 is increased. On the other hand, when the brake pedal 11 is returned, the rubber bushes 46 and 47 By releasing the deformation, the frictional force generated between the brake pedal 11 and the brake pedal 11 becomes constant, so that a pedaling force hysteresis is generated here. Therefore, a predetermined rigidity when the brake pedal 11 is operated and held can be ensured by the generated frictional force, and the restraining force on the operation side of the brake pedal 11 by the rubber bushes 46 and 47 is the restraining force on the return side. As a result, the feeling of operation of the brake pedal 11 by the occupant can be improved.

  The collars 44 and 45 are provided with flange portions 44 a and 45 a as a friction force limiting mechanism for limiting an increase in frictional force generated by the deformation of the rubber bushes 46 and 47. Therefore, as the brake pedal 11 is turned, the inclined portions 46a and 47a are deformed to the operation side by the collars 44 and 45, and the frictional force with which the protruding portions 46d and 47d are pressed against the side surface of the brake pedal 11 is increased. However, the protrusions 46b and 47b are locked to the flanges 44a and 45a, so that the deformation amount of the rubber bushes 46 and 47 is limited, and the pressing force to the side surface of the brake pedal 11 by the protrusions 46d and 47d, that is, The frictional force is limited, and the deterioration of the operation feeling of the brake pedal 11 and the deterioration of the rubber bushes 46 and 47 due to the increase of the frictional force more than necessary can be prevented.

  In this case, the stroke changing member and the frictional force applying member are constituted by the rubber bushes 46 and 47 as first and second elastic members, and intersect not only the rotation direction of the brake pedal 11 but also this rotation direction. It can also absorb directional wobbling. Then, collars 44 and 45 as load transmitters are mounted on the outer peripheral portion of the connecting shaft 18, and rubber bushes 46 and 47 are provided on the outer peripheral portions of the collars 44 and 45 to act on the clevis 16 and the brake pedal 11. . Therefore, the apparatus can be made compact and the mountability on the vehicle can be improved.

  In the second embodiment, the restraining force on the operation side of the brake pedal 11 is made larger than the restraining force on the return side by the rubber bushes 46 and 47, thereby improving the feeling of operation of the brake pedal 11 by the occupant. However, it is not limited to this configuration. For example, in the configuration of the first embodiment, the groove depth on the operation side of the brake pedal 11 is deeper than the groove depth on the return side at the groove portions 21a, 25a, 26a in the collars 21, 25, 26 that constitute the load transmitting member. By doing so, the restraining force on the operation side of the brake pedal 11 may be made larger than the restraining force on the return side.

  FIG. 6 is a horizontal sectional schematic configuration diagram of a brake operating device representing an operating device according to a third embodiment of the present invention. In addition, the same code | symbol is attached | subjected to the member which has the same function as what was demonstrated in the Example mentioned above, and the overlapping description is abbreviate | omitted.

  In the brake operating device according to the third embodiment, as shown in FIG. 6, the brake pedal 11 is supported by being suspended from the upper end of the brake pedal 11 so as to be rotatable. On the other hand, the operation rod 15 is connected to the clevis 16 by a screw portion 15a. The bifurcated portions 16a and 16b of the clevis 16 are positioned on both sides of the brake pedal 11, and the connecting shaft 18 penetrates the brake pedal 11 and the bifurcated portions 16a and 16b, so that they are rotatably connected to each other.

  In the brake operating device according to the present embodiment, a stroke changing member that can change the moving stroke of the operating rod 15 with respect to the operating stroke of the brake pedal 11 is interposed between the brake pedal 11 and the connecting shaft 18. . In the present embodiment, a frictional force applying member and a frictional force limiting mechanism are provided between the brake pedal 11 and the connecting shaft 18 so that a frictional force acts according to the operation of the brake pedal 11.

  In other words, the brake pedal 11 has a collar 51 fitted and fixed in the connecting hole 11a. The collar 51 has a cylindrical shape and is provided with 2 in the circumferential direction at each end in the axial direction on the inner peripheral surface. Two groove portions 51a and 51b are formed, and rubber O-rings 52 and 53 are attached to the groove portions 51a and 51b. The connecting shaft 18 passes through the collar 51 and is fitted through O-rings 52 and 53. In this case, a collar 51 is interposed between the brake pedal 11 and the connecting shaft 18, and O-rings 52 and 53 are interposed between the collar 51 and the connecting shaft 18, and the inner peripheral surface of the collar 51. And a predetermined gap is provided between the outer peripheral surface of the connecting shaft 18 and the O-rings 52 and 53 can be deformed by the amount of the gap.

  Further, the collar 51 is formed with a groove 51c along the circumferential direction between the axial positions on the inner peripheral surface, that is, between the grooves 51a and 51b, and a resin regulation ring 54 is attached to the groove 51c. The restriction ring 54 has a rectangular cross-sectional shape. Then, the connecting shaft 18 passes through the collar 51 and is fitted via a restriction ring 54. In this case, a collar 51 is interposed between the brake pedal 11 and the connecting shaft 18, a restriction ring 54 is interposed between the collar 51 and the connecting shaft 18, and an inner peripheral surface of the restriction ring 54 A predetermined gap is provided between the outer peripheral surface of the connecting shaft 18. The gap provided between the regulating ring 54 and the connecting shaft 18 is smaller than the gap provided between the collar 51 and the connecting shaft 18. That is, the O-rings 52 and 53 are crushed and deformed by the connecting shaft 18, so that the connecting shaft 18 comes into contact with the regulation ring 54 and does not come into contact with the collar 51.

  In this embodiment, the stroke changing member and the frictional force applying member of the present invention are first elastic members and are configured by O-rings 52 and 53, and the load transmitter of the present invention is configured by a collar 51. Is done. Further, the frictional force limiting mechanism of the present invention is constituted by the restriction ring 54.

  Accordingly, when the occupant steps on the brake pedal 11, the brake pedal 11 is rotated forward by the depression force. Then, the operation stroke (depression force) of the brake pedal 11 is transmitted as a movement stroke from the brake pedal 11 to the clevis 16 via the connecting shaft 18, and this movement stroke is further transmitted from the clevis 16 to the operation rod 15. The rod 15 moves forward.

  At this time, the connecting shaft 18 presses the O-rings 52 and 53 as the brake pedal 11 moves, so that the O-rings 52 and 53 are deformed. Therefore, rattling in the axial direction and the radial direction of the connecting shaft 18 is suppressed between the brake pedal 11 and the connecting shaft 18, and predetermined rigidity is ensured when the brake pedal 11 is operated and held.

  Further, the operation stroke generated by depressing the brake pedal 11 is partially absorbed by the deformation of the O-rings 52 and 53, and the movement stroke transmitted to the clevis 16 is changed (reduced). The In this case, since the stroke is absorbed by crushing the O-rings 52 and 53, the amount of absorption of this stroke is large at the initial depression of the brake pedal 11, and gradually decreases. Therefore, as the operation stroke by the brake pedal 11 increases, the movement stroke (stepping force) transmitted to the operation rod 15 is absorbed by the O-rings 52 and 53 for a predetermined period, and thus increases in a curve. It will be.

  On the other hand, when the brake pedal 11 is stepped on, the O-rings 52 and 53 are deformed by the connecting shaft 18 so that the frictional force between the O-rings 52 and 53 (brake pedal 11) and the connecting shaft 18 is increased. When the pedal 11 is returned, the frictional force does not become constant after the deformation of the O-rings 52 and 53 is released.

A stroke change member that can be transmitted to the brake booster via the brake pedal 11 and that can change the movement stroke of the operation rod 15 relative to the operation stroke of the brake pedal 11 between the brake pedal 11 and the connecting shaft 18, and the brake pedal 11 are interposed O-rings 52 and 53 that function as a frictional force applying member to which a frictional force is applied according to the operation of 11.

  Therefore, when the brake pedal 11 is depressed, the operation stroke of the brake pedal 11 is absorbed by the O-rings 52 and 53 and is transmitted to the operation rod 15 through the clevis 16 as a movement stroke. Accordingly, the movement stroke is reduced, and the feeling of operation of the brake pedal 11 by the occupant can be improved.

  That is, since the O-rings 52 and 53 are deformed by the connecting shaft 18 as the brake pedal 11 moves, the stroke (stepping force) is absorbed. Therefore, during the initial operation, the brake pedal 11, the connecting shaft 18, the clevis 16 It is possible to suppress the shakiness in the axial direction and the radial direction of the connecting shaft 18 between them, and to ensure a predetermined rigidity when the brake pedal 11 is operated and held. Then, with respect to the operation stroke generated by depressing the brake pedal 11, the movement stroke (stepping force) transmitted to the operation rod 15 increases in a quadratic curve. That is, when the depression amount of the brake pedal 11 is small, the stroke absorption amount becomes large and the sensitivity becomes bad. When the depression amount of the brake pedal 11 becomes large, the stroke absorption amount becomes small and the sensitivity becomes good. The operation feeling of the pedal 11 is improved.

  Further, when the brake pedal 11 is depressed, the O-rings 52 and 53 are deformed, so that the frictional force generated between the brake pedal 11 and the brake pedal 11 is increased. On the other hand, when the brake pedal 11 is returned, the O-rings 52 and 53 are deformed. Since the frictional force generated between the brake pedal 11 and the brake pedal 11 is reduced, the pedaling force hysteresis is generated here. Therefore, a predetermined rigidity when the brake pedal 11 is operated and held can be ensured by the generated frictional force, and the feeling of operation of the brake pedal 11 by the occupant can be improved.

  Further, when the brake pedal 11 is stepped on, after the O-rings 52 and 53 are deformed, the connecting shaft 18 comes into contact with the restriction ring 54, so that an increase in frictional force generated between the brake pedal 11 and the brake pedal 11 is limited. Thus, it is possible to prevent an increase in the frictional force and prevent the brake pedal 11 from deteriorating in feeling and the rubber bushes 46 and 47 from being deteriorated due to an increase in the frictional force more than necessary.

  In this case, the stroke changing member and the frictional force applying member are configured as O-rings 52 and 53 as first elastic members, and not only in the direction of rotation of the brake pedal 11 but also in the direction intersecting with this direction of rotation. It can also absorb rattling. A collar 51 as a load transmission element is fixed to the connecting hole 11 a of the brake pedal 11, and O-rings 52, 53, 54 are provided on the inner peripheral portion of the collar 51 to act on the connecting shaft 18. Therefore, the apparatus can be made compact and the mountability on the vehicle can be improved.
