Description

  The present invention relates to an accelerator device.

  2. Description of the Related Art An electronic accelerator device that detects a depression amount of an accelerator pedal with a sensor is known. An accelerator device disclosed in Patent Literature 1 includes an accelerator pedal rotatably supported by a housing, a link that can be engaged with the accelerator pedal in a circumferential direction when the accelerator pedal rotates to a fully open position, and an accelerator pedal. A first friction plate provided between the housing and a second friction plate provided between the link and the housing; The link is biased toward the fully closed position by a spring. The accelerator pedal is integrally formed with inclined teeth protruding toward the link side, and the link is integrally formed with inclined teeth protruding toward the accelerator pedal side. Each inclined tooth engages with each other as the accelerator pedal rotates from the fully closed position toward the fully open position, thereby separating the accelerator pedal and the link from each other in the axial direction.

The first friction plate frictionally engages the housing when the accelerator pedal is separated from the link, and provides rotational resistance to the accelerator pedal and the link. The second friction plate frictionally engages the housing when the link is separated from the accelerator pedal, and provides rotational resistance to the accelerator pedal and the link. These rotational resistances act so as to maintain the rotation of the accelerator pedal, and produce a characteristic in which the pedaling force when the accelerator pedal is depressed is smaller than the pedaling force when the accelerator pedal is depressed, that is, a so-called pedaling force hysteresis characteristic.

JP 2014-141147 A

  By the way, in patent document 1, the housing is comprised by one member. In order to suppress the breakage of the housing as the support means for supporting the friction plate pressed by the inclined teeth, strength, toughness, and cold resistance (resistance to repeated expansion and contraction due to the cold cycle) are required. In order to improve the strength, it is considered that the base resin contains reinforcing fibers such as glass fibers. In order to improve the toughness, it is conceivable to employ, for example, a polyamide resin as the base resin. In order to improve the heat resistance, it is considered that the base resin contains, for example, an elastomer.

  However, if the slidable contact portion that frictionally engages with the friction plate contains reinforcing fibers, the wear of the slidable contact portion becomes aggressive wear, and there is a disadvantage that the variation in the pedaling force characteristic becomes large. In addition, since polyamide resin easily absorbs water, if there is a polyamide resin in the sliding contact portion, there is a drawback that the coefficient of treading force changes greatly due to the increased coefficient of friction due to water absorption. In addition, since the elastomer has a relatively large friction coefficient, if the elastomer is contained in the sliding contact portion, there is a drawback that the friction coefficient increases and the pedaling force characteristic changes greatly.

That is, there is a difference between the function required as the support means and the function required as the friction engagement means, and there is a problem that it is difficult to satisfy both with one member.
The present invention has been made in view of the above-described points, and an object of the present invention is to provide an accelerator device that can suppress fluctuations in pedal force characteristics while suppressing breakage of a housing.

The present invention includes a first invention in which two friction plates are provided and a second invention in which one friction plate is provided.
The first invention is a first friction plate provided between the accelerator pedal and the housing and fixed to the accelerator pedal, and a second friction plate provided between the link and the housing and fixed to the link. As the pedal rotation angle increases, the frictional force between the first friction plate and the housing and the frictional force between the second friction plate and the housing increase, and rotational resistance is applied to the accelerator pedal and the link. And pressing means for pressing the second friction plate against the housing.

  The housing has a base, a first sliding contact member, and a second sliding contact member. The base can be attached to the vehicle body and rotatably supports the accelerator pedal. The first sliding contact member is a separate member from the base and the first friction plate, is provided between the base and the first friction plate, is fixed to the base, and can be frictionally engaged with the first friction plate. is there. The second sliding contact member is a separate member from the base and the second friction plate, is provided between the base and the second friction plate, is fixed to the base, and can be frictionally engaged with the second friction plate. is there.

  The second invention is provided on the opposite side of the link in the axial direction of the accelerator pedal, and is provided between the accelerator pedal and the supporter. The friction plate that is fixed to the pedal and the pressing means that presses the friction plate against the support so that the frictional force between the friction plate and the support increases as the pedal rotation angle increases and rotational resistance is applied to the accelerator pedal and the link. And comprising.

  The supporter has a base and a sliding contact member. The base is formed integrally with the link and is rotatable integrally with the link. The sliding contact member is a separate member from the base and the friction plate, is provided between the base and the friction plate, is fixed to the base, and can be frictionally engaged with the friction plate.

  Thus, by configuring the base as the support means and the sliding contact member as the friction engagement means from separate members, different materials can be selected for each means. Thereby, the function calculated | required as a support means can be optimally provided to a base, and the function calculated | required as a friction engagement means can be optimally provided to a sliding contact member. Therefore, according to the present invention, it is possible to suppress fluctuations in pedaling force characteristics while suppressing damage to the housing or the supporter.

Hereinafter, a plurality of embodiments of the present invention will be described with reference to the drawings. In the embodiments, substantially the same components are denoted by the same reference numerals and description thereof is omitted.
[First Embodiment]
An accelerator apparatus according to a first embodiment of the present invention is shown in FIG. The accelerator device 10 is an input device operated by a driver in order to adjust the driving state of a vehicle engine (not shown). The accelerator device 10 is electronic, and transmits an electric signal indicating the depression amount of the accelerator pedal 12 to an electronic control device (not shown). The electronic control device drives the throttle valve based on the electric signal transmitted from the accelerator device 10.

(overall structure)
First, the whole structure of the accelerator apparatus 10 is demonstrated with reference to FIGS. The accelerator device 10 shown in FIGS. 1 and 2 is shown in a positional relationship where it is attached to the vehicle body 100.
As shown in FIGS. 1 and 2, the accelerator device 10 includes a housing 11, an accelerator pedal 12, a link 13, springs 14 and 15, a rotation angle sensor 16, a first friction plate 17, and a second friction plate 18. .
The housing 11 is formed in a box shape, and can be attached to the vehicle body 100 with, for example, bolts, and has an opening on the ground side when attached.

The accelerator pedal 12 has a shaft 20, a pedal rotor 21, a rod 22 and a pad 23.
The shaft 20 is rotatably supported by a pair of bearing walls 24 and 25 included in the housing 11. A sensor installation hole 26 is formed at one end of the shaft 20.
The pedal rotor 21 includes a first boss portion 27 that is fitted to the shaft 20 in the housing 11 and is fixed to the shaft 20, and a connecting portion 28 that extends downward from the first boss portion 27. The rod 22 is fixed to the connecting portion 28. The pad 23 is fixed to the lower end portion of the rod 22.

  The connecting portion 28 is formed with a fully closed stopper 29 that contacts the housing 11 at the fully closed position that is the original position, and a fully open stopper 30 that contacts the housing 11 at the fully opened position that is the maximum operation position. The accelerator pedal 12 can rotate from a fully closed position to a fully open position. Hereinafter, the rotation direction of the accelerator pedal 12 from the fully closed position toward the fully open position is referred to as “accelerator opening direction”, and the rotation direction of the accelerator pedal 12 from the fully open position toward the fully closed position is referred to as “accelerator closing direction”. The rotation angle of the accelerator pedal 12 from the fully closed position is referred to as “pedal rotation angle”.

  A plurality of first oblique teeth 31 are formed on the second boss portion 33 side described later in the first boss portion 27. The first inclined teeth 31 are arranged at intervals in the circumferential direction. The 1st inclined tooth 31 has the 1st slope 32 located in the 2nd boss | hub part 33 side, so that it goes to an accelerator closing direction.

  The link 13 includes a second boss portion 33 into which the shaft 20 is inserted in the housing 11 and is rotatable relative to the shaft 20, and a spring locking portion 34 protruding upward from the second boss portion 33. . A plurality of second oblique teeth 35 are formed on the first boss portion 27 side of the second boss portion 33. The second inclined teeth 35 are arranged one by one between the first inclined teeth 31 and have a second inclined surface 36 that is positioned closer to the first boss portion 27 toward the accelerator opening direction.

  The first inclined teeth 31 and the second inclined teeth 36 can transmit rotation between the accelerator pedal 12 and the link 13 when the inclined surfaces come into contact with each other. That is, the rotation of the accelerator pedal 12 in the accelerator opening direction can be transmitted to the link 13 via the first inclined teeth 31 and the second inclined teeth 36. Further, the rotation of the link 13 in the accelerator closing direction can be transmitted to the accelerator pedal 12 via the second inclined teeth 36 and the first inclined teeth 31.

In addition, when the accelerator pedal 12 rotates in the accelerator opening direction, the first inclined teeth 31 and the second inclined teeth 36 have the inclined surfaces come into contact with each other so that the first boss portion 27 and the second boss portion 33 are pivoted to each other. Separate in the direction. At this time, the first inclined teeth 31 push the second boss portion 33 to the opposite side to the first boss portion 27 with a greater force as the pedal rotation angle increases. Further, the second inclined teeth 36 push the first boss portion 27 to the opposite side to the second boss portion 33 with a greater force as the pedal rotation angle increases.

  The springs 14 and 15 are provided between the spring locking portion 34 and the housing 11 and urge the link 13 in the accelerator closing direction. The urging force of the springs 14 and 15 increases as the pedal rotation angle increases. The springs 14 and 15 correspond to “biasing means” described in the claims.

  The rotation angle sensor 16 includes a magnetic detection element 37 provided in the sensor installation hole 26 and a pair of magnets 38 and 39 fixed to the inner wall of the sensor installation hole 26. The magnetic detection element 37 outputs an electrical signal corresponding to the magnetic flux density that changes as the shaft 20 rotates. The rotation angle sensor 16 can detect the pedal rotation angle, and corresponds to “rotation angle detection means” described in the claims.

  The first friction plate 17 is provided on the opposite side of the first boss portion 27 from the second boss portion 33 and between the first boss portion 27 and the housing 11. It is fixed. The first friction plate 17 is pressed against the housing 11 when the first boss portion 27 is pressed away from the second boss portion 33. The frictional force between the first friction plate 17 and the housing 11 at this time becomes the rotational resistance of the accelerator pedal 12 and the link 13.

  The second friction plate 18 is provided on the opposite side of the second boss portion 33 from the first boss portion 27 and between the second boss portion 33 and the housing 11. It is fixed. The second friction plate 18 is pressed against the housing 11 when the second boss 33 is pressed away from the first boss 27. The frictional force between the second friction plate 18 and the housing 11 at this time becomes the rotational resistance of the accelerator pedal 12 and the link 13.

  In the accelerator device 10 configured as described above, the rotation of the accelerator pedal 12 in the accelerator opening direction is transmitted to the link 13 by the engagement between the first inclined surface 32 and the second inclined surface 36. At this time, the first inclined teeth 31 and the second inclined teeth 35 increase the frictional force between the friction plates 17 and 18 and the housing 11 as the pedal rotation angle increases, and imparts rotational resistance to the pedal rotor 21 and the link 13. In this manner, the friction plates 17 and 18 are pressed against the housing 11.

  The rotational resistance acts so that the pedaling force increases as shown by a solid line in FIG. 3 when the accelerator pedal 12 is depressed, and the pedaling force decreases as shown by a one-dot chain line in FIG. 3 when the accelerator pedal 12 is returned. Act on. That is, the relationship between the pedaling force and the pedal rotation angle is a relationship in which a hysteresis loop is drawn so that the pedaling force is different between when the pedal rotation angle is increased and when the pedal rotation angle is decreased. The first inclined teeth 31 and the second inclined teeth 35 constitute “pressing means” described in the claims.

(Feature configuration)
Next, the characteristic structure of the accelerator apparatus 10 is demonstrated with reference to FIG. 2, FIG. 4-FIG.
As shown in FIGS. 2 and 4, the housing 11 includes a base 40, a first slidable contact member 41, and a second slidable contact member 42, which are composed of different members.
The base 40 includes a support portion 43 including the bearing walls 24 and 25 and an attachment portion 44 that can be attached to the vehicle body 100. The bearing walls 24 and 25 have through holes 45 and 46 into which the shaft 20 is inserted.

  As shown in FIGS. 4 and 5, the first slidable contact member 41 includes a ring portion 47 through which the shaft 20 is inserted, and a press-fit protrusion 49 that is press-fit into the press-fit hole 48 of the base 40. The ring portion 47 is provided between the base 40 and the first friction plate 17. The ring portion 47 includes a first fixed surface 50 that is in contact with the base 40 and a first sliding contact surface 51 that can be frictionally engaged with the first friction plate 17. In the present embodiment, the first fixed surface 50 is parallel to the first sliding contact surface 51.

  As shown in FIGS. 4 and 6, the second slidable contact member 42 includes a ring portion 52 through which the shaft 20 is inserted, and a press-fit protrusion 54 that is press-fit into the press-fit hole 53 of the base 40. The ring portion 52 is provided between the base 40 and the second friction plate 18. The ring portion 52 includes a second fixed surface 55 that is in contact with the base 40 and a second sliding contact surface 56 that can be frictionally engaged with the second friction plate 18. In the present embodiment, the second fixed surface 55 is parallel to the second sliding contact surface 56.

  Here, the conventional housing was comprised by one member. A housing as a supporting means for supporting the pressed friction plate has been required to have strength, toughness, and heat resistance. In order to improve the strength, it is considered that the base resin contains reinforcing fibers such as glass fibers. In order to improve the toughness, it is conceivable to employ, for example, a polyamide resin as the base resin. In order to improve the heat resistance, it is considered that the base resin contains, for example, an elastomer.

However, if the slidable contact portion that frictionally engages with the friction plate contains reinforcing fibers, the wear of the slidable contact portion becomes aggressive wear, and there is a disadvantage that the variation in the pedaling force characteristic becomes large. In addition, since polyamide resin easily absorbs water, if there is a polyamide resin in the sliding contact portion, there is a drawback that the coefficient of treading force changes greatly due to the increased coefficient of friction due to water absorption. In addition, since the elastomer has a relatively large friction coefficient, if the elastomer is contained in the sliding contact portion, there is a drawback that the friction coefficient increases and the pedaling force characteristic changes greatly.
That is, there is a difference between the function required as the support means and the function required as the friction engagement means, and there is a problem that it is difficult to satisfy both with one member.

  On the other hand, in the present embodiment, the housing 11 includes a base 40 as support means, and a first sliding contact member 41 and a second sliding contact member 42 as friction engagement means. The base 40 is made of a polyamide resin containing reinforcing fibers and an elastomer, and has functions required as a support means, that is, high strength, high toughness, and cold resistance. Further, the sliding contact members 41 and 42 are made of, for example, polybutylene terephthalate (PBT) resin having a low water absorption rate, and have the property that the frictional engagement means is required, that is, the coefficient of friction hardly changes depending on the environment. Yes.

(effect)
As described above, the housing 11 of the accelerator apparatus 10 according to the first embodiment includes the base 40 and the first sliding contact member 41 and the second sliding contact member 42 which are members different from the base 40. The base 40 can be attached to the vehicle body 100 and supports the accelerator pedal 12 in a rotatable manner. The first sliding contact member 41 is provided between the base 40 and the first friction plate 17, is fixed to the base 40, and can be frictionally engaged with the first friction plate 17. The second sliding contact member 42 is provided between the base 40 and the second friction plate 18, is fixed to the base 40, and can be frictionally engaged with the second friction plate 18.

In this way, by configuring the support means and the friction engagement means from different members, different materials can be selected for each means. Accordingly, the function required as the support means can be optimally imparted to the base 40, and the function required as the friction engagement means can be optimally imparted to the first sliding contact member 41 and the second sliding contact member 42.
Therefore, according to 1st Embodiment, the fluctuation | variation of pedal effort characteristic can be suppressed, suppressing the damage of the housing 11. FIG.

  Here, the conventional housing which consists of one member had the 1st sliding contact surface and the 2nd sliding contact surface which friction-engage with each friction board, and was a complicated shape which has a rib etc. further. In a housing that is such a complicated and relatively large molded product, it has been difficult to modify the mold in order to adjust the distance between the first sliding contact surface and the second sliding contact surface.

  On the other hand, in the first embodiment, the sliding contact members 41 and 42 as the friction engagement means are provided separately from the base 40 as the support means. Therefore, it is easy to correct the mold of the slidable contact members 41 and 42 which are simple shapes and relatively small molded products, and the first slidable contact surface 51 and the second slidable contact surface 56 are corrected by the correction. The interval can be adjusted. By adjusting this distance, it is possible to tune the pedaling force characteristics by changing the set length of the springs 14 and 15.

[Second Embodiment]
An accelerator apparatus according to a second embodiment of the present invention will be described with reference to FIG.
As shown in FIG. 7, the first fixed surface 61 and the first sliding contact surface 62 of the first sliding contact member 60 are not parallel. That is, the first sliding contact surface 62 has a different inclination angle from the first fixed surface 61.
Further, the second fixed surface 64 of the second sliding contact member 63 and the second sliding contact surface 65 are not parallel. That is, the second sliding contact surface 65 is different in inclination angle from the second fixed surface 64.

Here, in the conventional housing which consists of one member, it was difficult to adjust the parallelism of the 1st sliding contact surface and the 2nd sliding contact surface.
On the other hand, in the second embodiment, sliding contact members 60 and 63 as friction engagement means are provided separately from the base 40 as support means. Therefore, it is easy to correct the molds of the sliding contact members 60 and 63 which are simple shapes and relatively small molded products, and the fixed surfaces 61 and 64 are inclined with respect to the sliding contact surfaces 62 and 65 by the correction. By adjusting the angles to be different, the parallelism between the first sliding contact surface 62 and the second sliding contact surface 65 can be improved.

[Third Embodiment]
An accelerator apparatus according to a third embodiment of the present invention will be described with reference to FIGS.
As shown in FIGS. 8 and 9, the first slidable contact member 70 and the second slidable contact member 71 are made of a thin metal plate.
The first sliding contact member 70 has a detent protrusion 72 that protrudes radially outward from the ring portion 47. The anti-rotation protrusion 72 is fitted in the engagement groove 73 of the bearing wall 24 and engages with the engagement groove 73 to prevent the first sliding contact member 70 from rotating.

The second slidable contact member 71 has a detent protrusion 74 that protrudes radially outward from the ring portion 52. The anti-rotation protrusion 74 is fitted in the engagement groove 75 of the bearing wall 25 and engages with the engagement groove 75 to prevent the second sliding contact member 71 from rotating.
Thus, the flatness and wear resistance of the sliding surfaces 76 and 77 can be improved by configuring the sliding contact members 70 and 71 from metal thin plates. Also, the axial size of the apparatus can be reduced.

[Fourth Embodiment]
An accelerator apparatus according to a fourth embodiment of the present invention will be described with reference to FIG.
As shown in FIG. 10, the housing 11 includes a shim plate 80 that is sandwiched between the base 40 and the first sliding contact member 41.

Here, as described above, it is difficult to modify the mold in order to adjust the distance between the first sliding contact surface and the second sliding contact surface in the conventional housing formed of one member.
On the other hand, in the fourth embodiment, by adjusting the thickness of the shim plate 80, the distance between the first sliding contact surface 51 and the second sliding contact surface 56 is easily adjusted without modifying the mold. be able to. By adjusting this distance, it is possible to tune the pedaling force characteristics by changing the set length of the springs 14 and 15. By the above tuning, for example, variation in pedaling force characteristics in one model can be reduced, and a difference in pedaling force characteristics can be set between other models.

[Fifth Embodiment]
An accelerator apparatus according to a fifth embodiment of the present invention will be described with reference to FIG.
As shown in FIG. 11, a supporter 90 is provided on the opposite side of the first boss portion 27 from the second boss portion 33 in the axial direction of the accelerator pedal 12. The supporter 90 is formed integrally with the link 13.
