　従来より、車両用のディスクブレーキ装置として、車輪とともに回転するディスクを一対の制輪子で挟持してブレーキをかけるように構成されたディスクブレーキ装置が提案されている（例えば、特許文献１）。 Conventionally, as a disc brake device for a vehicle, there has been proposed a disc brake device configured to apply a brake by sandwiching a disc rotating with a wheel between a pair of restrictors (for example, Patent Document 1).
　従来では、例えば、ディスクブレーキ装置は、車輪と一体回転するディスクを挟むように対向配置される一対の制輪子と、これら制輪子をディスクに対して移動可能に支持するキャリパボディと、このキャリパボディを車両の台車枠に連結するキャリパ連結手段とを備えている。
　キャリパボディは、制輪子をディスクへ押付けるためのピストンを備えており、このピストンは、空気圧又は油圧等の流体圧により駆動されて、制輪子をディスク側に押付けるようになっている。 2. Description of the Related Art Conventionally, for example, a disc brake device includes a pair of restrictors disposed so as to sandwich a disc that rotates integrally with a wheel, a caliper body that supports these restrictors so as to be movable with respect to the disc, and the caliper body. Caliper connecting means for connecting the vehicle to the bogie frame of the vehicle.
The caliper body is provided with a piston for pressing the restrictor against the disc, and this piston is driven by a fluid pressure such as air pressure or hydraulic pressure to press the restrictor toward the disc.
　また、従来のディスクブレーキ装置では、キャリパボディの振れを防止するためにダンパが設けられており、ダンパは、一端がキャリパボディに軸支されるとともに他端が車両の台車枠に軸支されている。ダンパは、ダンパ本体と、このダンパ本体の外周に配置された緩衝用ばね部材とを有しており、ダンパは、衝撃が加わった際にダンパ本体が伸縮することによりキャリパボディにかかる衝撃を吸収するようになっている。
　また、従来のディスクブレーキ装置では、ダンパに加えて、台車枠にストッパが設けられており、キャリパボディが振動する際にストッパの先端部がキャリパボディに接触し、キャリパボディが規定以上の範囲で振れるのを防止するようになっている。 Further, in the conventional disc brake device, a damper is provided to prevent the caliper body from swinging, and one end of the damper is pivotally supported by the caliper body and the other end is pivotally supported by the bogie frame of the vehicle. Yes. The damper has a damper main body and a buffer spring member disposed on the outer periphery of the damper main body, and the damper absorbs the shock applied to the caliper body by the expansion and contraction of the damper main body when an impact is applied. It is supposed to be.
In addition, in the conventional disc brake device, in addition to the damper, a stopper is provided on the carriage frame, and when the caliper body vibrates, the tip of the stopper comes into contact with the caliper body, and the caliper body is within the specified range. It is designed to prevent shaking.

　しかしながら、上述の従来の構成では、キャリパボディの振れを防止するためにダンパ及びストッパ等の多く部品が必要となり、ディスクブレーキ装置の部品点数が多くなるという問題があった。加えて、キャリパボディと車両の台車枠との間にダンパを設けるような構成となっているので、台車枠にダンパを設置するためのスペースを確保しなければならず、ディスクブレーキ装置全体の構成が大きくなってしまうという問題もあった。 However, the conventional configuration described above has a problem that many parts such as a damper and a stopper are required to prevent the caliper body from swinging, and the number of parts of the disc brake device increases. In addition, since a damper is provided between the caliper body and the bogie frame of the vehicle, a space for installing the damper on the bogie frame must be secured, and the entire disc brake device configuration There was also a problem that became larger.
　また、上述の従来の構成では、例えば、制輪子が磨耗した状態で、制輪子をピストンによってディスクの側面に向かって押付けると、一対の制輪子が平行でない状態でディスクに接触する可能性がある。一対の制輪子が平行でない状態でディスクに接触すると、制輪子がディスクの回転を制動しにくくなり、その結果、ブレーキ精度が低下してしまうという問題がある。また、一対の制輪子が平行でない状態でディスクに接触するので、制輪子が偏磨耗し、制輪子のライフサイクルが短くなる可能性もある。 Further, in the above-described conventional configuration, for example, when the control member is worn toward the side surface of the disc by the piston while the control member is worn, there is a possibility that the pair of control members may contact the disc without being parallel. is there. If the pair of restrictors come into contact with the disk in a state where they are not parallel, there is a problem that it becomes difficult for the restrictor to brake the rotation of the disk, and as a result, the brake accuracy decreases. In addition, since the pair of restrictors contact the disk in a state where they are not parallel, the restrictor may be worn away, and the life cycle of the restrictor may be shortened.
　本発明はこのような実情に鑑みてなされたものであって、その目的は、部品点数が少なく且つ設置スペースも小さい構成で制輪子の振動を抑制するとともに、制輪子が磨耗した状態でもブレーキ精度を維持することが可能なディスクブレーキ装置を提供することである。 The present invention has been made in view of such circumstances, and its purpose is to suppress the vibration of the brake with a configuration having a small number of parts and a small installation space, and to improve the brake accuracy even when the brake is worn. It is an object to provide a disc brake device capable of maintaining the above.
　上記従来技術の有する課題を解決するために、本発明の実施態様によれば、車輪と一体に回転するディスクを挟むように対向して配置されるとともに前記ディスク側にパッドが配設された一対の制輪子受けと、該一対の制輪子受けが回動軸を介して取付けられた一対のアームと、該一対のアームに連結されるとともに前記一対の制輪子受けを前記一対のアームを介して前記ディスク側へ押し出すように構成された駆動機構とを備えているディスクブレーキ装置において、前記制輪子受けと前記アームとの間には、前記制輪子受けの動きを規制するように構成された摩擦機構が設けられている。 In order to solve the above-described problems of the prior art, according to an embodiment of the present invention, a pair of discs that are disposed to face each other so as to sandwich a disc that rotates integrally with a wheel and that has a pad disposed on the disc side. And a pair of arms to which the pair of brake restrainer receivers are attached via a rotation shaft, and the pair of armor receivers are connected to the pair of arms and the pair of brake restrainer receivers are connected to the pair of arms via the pair of arms. In a disc brake device comprising a drive mechanism configured to push out toward the disc side, a friction configured to regulate movement of the control member receiver between the control member receiver and the arm. A mechanism is provided.
　また、本発明の別の実施態様によれば、前記摩擦機構が、前記制輪子受けと前記アームとの間に配置された摩擦板と、該摩擦板を前記制輪子受け側へ向かって付勢する付勢手段とを備えている。 According to another embodiment of the present invention, the friction mechanism includes a friction plate disposed between the brake receiver and the arm, and biases the friction plate toward the brake receiver. And urging means for
　また、本発明の別の実施態様によれば、前記アームは、上下方向に対向して配置された一対の支持アーム部を備え、前記制輪子受けは、前記一対の支持アーム部の間に延出した一対のリブを備え、前記摩擦機構の前記付勢手段は、前記一対のリブの間に配置された付勢部材と、該付勢部材と前記一対のリブとの間に配置されるとともに前記付勢部材を上下方向で保持する一対の受け部材とを備え、前記アームと前記制輪子受けとは、前記一対の支持アーム部と前記一対のリブとを連通する支持ピンにより連結され、前記一対のリブと前記一対の受け部材との間には、前記摩擦機構の前記摩擦板がそれぞれ配置されている。 Further, according to another embodiment of the present invention, the arm includes a pair of support arm portions disposed so as to face each other in the vertical direction, and the stabilizer receiver extends between the pair of support arm portions. A biasing member disposed between the pair of ribs; and a biasing member disposed between the pair of ribs; and a biasing member disposed between the pair of ribs. A pair of receiving members for holding the urging member in the vertical direction, and the arm and the control member receiver are connected by a support pin that communicates the pair of support arm portions and the pair of ribs, The friction plates of the friction mechanism are respectively disposed between the pair of ribs and the pair of receiving members.
　また、本発明の別の実施態様によれば、前記一対のリブには、前記一対の制輪子受けの前記パッドが前記ディスクを挟む際に前記制輪子受けの回転に対して前記支持ピンが干渉しないように移動するための切欠きが設けられている。 According to another embodiment of the present invention, the support pin interferes with the pair of ribs when the pad of the pair of restrictor receivers sandwiches the disk when the pads sandwich the disk. Notches are provided for movement so as not to move.
　また、本発明の別の実施態様によれば、前記切欠きは、前記制輪子受けの前記回動軸を中心として前記支持ピンが移動する軌道に沿って形成された円弧状の切欠き部である。 Further, according to another embodiment of the present invention, the notch is an arc-shaped notch formed along a track along which the support pin moves around the rotation shaft of the restrictor receiver. is there.
　また、本発明の別の実施態様によれば、前記摩擦機構が、前記制輪子受けの前記回動軸に対して前記駆動機構側に配置されている。 Further, according to another embodiment of the present invention, the friction mechanism is disposed on the drive mechanism side with respect to the rotating shaft of the brake support.
　上述の如く、本発明に係るディスクブレーキ装置によれば、車輪と一体に回転するディスクを挟むように対向して配置されるとともに前記ディスク側にパッドが配設された一対の制輪子受けと、該一対の制輪子受けが回動軸を介して取付けられた一対のアームと、該一対のアームに連結されるとともに前記一対の制輪子受けを前記一対のアームを介して前記ディスク側へ押し出すように構成された駆動機構とを備えているディスクブレーキ装置において、前記制輪子受けと前記アームとの間には、前記制輪子受けの動きを規制するように構成された摩擦機構が設けられているので、車両の運転中にアームが振動した場合、制輪子受けとアームとの間に摩擦力が働くことにより制輪子受けがアームの振動の影響を受けにくくなり、その結果、制輪子受けが振動することを抑制することができる。また、制輪子受けとアームとの間に摩擦機構のみを設ければよい構成であるので、従来のような台車枠にダンパを設けるような構成に比べて、ディスクブレーキ装置全体の構成のコンパクト化を図ることができる。 As described above, according to the disc brake device of the present invention, a pair of brake bearing receivers arranged to face each other so as to sandwich the disc that rotates integrally with the wheel and with a pad disposed on the disc side, A pair of arms attached to the pair of brake restrictors via a rotation shaft; and a pair of arms connected to the pair of arms and pushing the pair of restrictor receptacles toward the disk via the pair of arms. In the disc brake device including the drive mechanism configured as described above, a friction mechanism configured to regulate the movement of the brake shoe receiver is provided between the brake shoe receiver and the arm. Therefore, when the arm vibrates during the operation of the vehicle, the frictional force acts between the armor receiver and the arm, so that the armor receiver becomes less affected by the arm vibration. Waco receiving can be prevented from being vibrated. In addition, since only the friction mechanism needs to be provided between the brake pad receiver and the arm, the overall configuration of the disc brake device is made compact compared to the conventional configuration in which the damper is provided on the bogie frame. Can be achieved.
　また、本発明に係るディスクブレーキ装置によれば、前記摩擦機構が、前記制輪子受けと前記アームとの間に配置された摩擦板と、該摩擦板を前記制輪子受け側へ向かって付勢する付勢手段とを備えているので、付勢手段により摩擦板が常に制輪子受け側に押付けられることなり、制輪子受けとアームとの間に確実に摩擦を発生させることができる。その結果、より効果的に制輪子受けが振動することを抑制することができる。
　また、摩擦機構が摩擦板と付勢手段とからなる簡易な構成であるので、従来のダンパを設けるような構成に比べて、部品点数が少なく且つ摩擦機構自体の設置スペースも小さくすることができる。 In the disc brake device according to the present invention, the friction mechanism includes a friction plate disposed between the brake bearing receiver and the arm, and biases the friction plate toward the brake bearing receiver side. Therefore, the friction plate is always pressed against the side of the restrictor receiver by the urging means, and friction can be reliably generated between the restrictor receiver and the arm. As a result, it is possible to more effectively suppress the vibration absorber receiver from vibrating.
In addition, since the friction mechanism has a simple configuration including a friction plate and an urging means, the number of parts can be reduced and the installation space for the friction mechanism itself can be reduced as compared with a configuration in which a conventional damper is provided. .
　また、本発明に係るディスクブレーキ装置によれば、前記アームは、上下方向に対向して配置された一対の支持アーム部を備え、前記制輪子受けは、前記一対の支持アーム部の間に延出した一対のリブを備え、前記摩擦機構の前記付勢手段は、前記一対のリブの間に配置された付勢部材と、該付勢部材と前記一対のリブとの間に配置されるとともに前記付勢部材を上下方向で保持する一対の受け部材とを備え、前記アームと前記制輪子受けとは、前記一対の支持アーム部と前記一対のリブとを連通する支持ピンにより連結され、前記一対のリブと前記一対の受け部材との間には、前記摩擦機構の前記摩擦板がそれぞれ配置されているので、上下一対の支持アーム部の各々について制輪子受けとの間で摩擦力が働くことになり、制輪子受けがアームの振動の影響をより受けにくくなる。これにより、より効果的に制輪子受けが振動することを抑制することができる。 Further, according to the disc brake device according to the present invention, the arm includes a pair of support arm portions disposed so as to face each other in the vertical direction, and the restrictor receiver extends between the pair of support arm portions. A biasing member disposed between the pair of ribs; and a biasing member disposed between the pair of ribs; and a biasing member disposed between the pair of ribs. A pair of receiving members for holding the urging member in the vertical direction, and the arm and the control member receiver are connected by a support pin that communicates the pair of support arm portions and the pair of ribs, Since the friction plates of the friction mechanism are respectively disposed between the pair of ribs and the pair of receiving members, a frictional force is exerted between the upper and lower pair of support arm portions between the pair of upper and lower support arms. That ’s why, Over less susceptible more the influence of the vibration of the beam. Thereby, it can suppress that a brake pad receiver vibrates more effectively.
　また、本発明に係るディスクブレーキ装置によれば、前記一対のリブには、前記一対の制輪子受けの前記パッドが前記ディスクを挟む際に前記制輪子受けの回転に対して前記支持ピンが干渉しないように移動するための切欠きが設けられているので、一対の制輪子がディスクを挟んだ際に切欠きによって支持ピンが移動することにより、制輪子受けのパッドの表面をディスクに対して常に一定の距離を開けた状態で平行に保持することができる。これにより、制輪子受けのパッドが磨耗した状態でも、制輪子受けのパッドの表面がディスクに対して平行な状態で接触することになり、ブレーキ精度の低下を防止することができる。 According to the disc brake device of the present invention, the support pin interferes with the pair of ribs when the pad of the pair of restrictor receivers sandwiches the disc when the pads sandwich the disc. The notch is provided so that the support pin moves by the notch when the pair of restrictors sandwich the disk, so that the surface of the pad of the restrictor receiver is moved relative to the disk. It can always be held parallel with a certain distance. As a result, even when the pad of the brake pad receiver is worn, the surface of the pad of the brake pad receiver is in contact with the disk in a parallel state, and a reduction in brake accuracy can be prevented.
　また、本発明に係るディスクブレーキ装置によれば、前記切欠きは、前記制輪子受けの前記回動軸を中心として前記支持ピンが移動する軌道に沿って形成された円弧状の切欠き部であるので、一対のリブに支持ピンの軌道に沿った最小限の加工を行うだけでよく、切欠き全体の構成のコンパクト化を図ることができる。 In the disc brake device according to the present invention, the notch is an arc-shaped notch formed along a track along which the support pin moves around the rotation shaft of the brake support. Therefore, it is only necessary to perform a minimum processing along the track of the support pin on the pair of ribs, and the overall configuration of the notch can be made compact.
　また、本発明に係るディスクブレーキ装置によれば、前記摩擦機構が、前記制輪子受けの前記回動軸に対して前記駆動機構側に配置されているので、内周締結型のディスクに対応させるために、制輪子受けをディスクのボルトと干渉しないように切欠いて形成した場合でも、摩擦機構により制輪子受けの振動を抑制することができる。 In the disc brake device according to the present invention, since the friction mechanism is disposed on the drive mechanism side with respect to the rotation shaft of the brake bearing receiver, it is made to correspond to an inner periphery fastening type disc. For this reason, even when the control member is cut out so as not to interfere with the bolts of the disk, the vibration of the control member can be suppressed by the friction mechanism.

When the expansion / contraction part of the cylinder mechanism 5 is extended, the cylinder mechanism side end parts 14a and 14b are pushed out in directions away from each other.
Each support arm portion 12a, 12b has a fulcrum shaft 15a connected to a vehicle frame (not shown) at a substantially intermediate position between the holder side end portions 13a, 13b and the cylinder mechanism side end portions 14a, 14b. , 15b. Thus, when the cylinder mechanism side end portions 14a and 14b of the support arm portions 12a and 12b are pushed away from each other, the support arm portions 12a and 12b rotate about the fulcrum shafts 15a and 15b, and the support arm portion 12a. , 12b are pushed to the disk 2 side.
　本実施形態では、図１及び図３に示すように、各ホルダ３ａ，３ｂの外側表面９ａ，９ｂには、回動軸１１ａ，１１ｂに対してシリンダ機構５側の位置において一対のリブ１７ａ，１７ｂが設けられている。この一対のリブ１７ａ，１７ｂは、一対の支持アーム部１２ａ，１２ｂの間に配置されている。 In this embodiment, as shown in FIGS. 1 and 3, the outer surfaces 9a and 9b of the holders 3a and 3b are provided with a pair of ribs 17a and 17b at positions on the cylinder mechanism 5 side with respect to the rotation shafts 11a and 11b. 17b is provided. The pair of ribs 17a and 17b are disposed between the pair of support arm portions 12a and 12b.
　また、図３に示すように、一対のリブ１７ａ，１７ｂの間には、摩擦機構１８ａ，１８ｂが設けられおり、一対の支持アーム部１２ａ，１２ｂと一対のリブ１７ａ，１７ｂとは、摩擦機構１８ａ，１８ｂを介して連結されている。以下では、図４を用いて摩擦機構１８ａについて説明する。
　図４に示すように、摩擦機構１８ａは、一対のリブ１７ａとの間に配置された一対の受け部材１９ａと、一対の受け部材１９ａの間で保持されるように配置された付勢部材２０ａと、一対のリブ１７ａと一対の受け部材１９ａとの間にそれぞれ配置された２枚の摩擦板２１ａとから構成されている。そして、一対の支持アーム部１２ａと一対のリブ１７ａと一対の受け部材１９ａと摩擦板２１ａとは、支持ピン２２ａをそれぞれに挿通することによりに連結されている。 Further, as shown in FIG. 3, friction mechanisms 18a and 18b are provided between the pair of ribs 17a and 17b, and the pair of support arm portions 12a and 12b and the pair of ribs 17a and 17b include a friction mechanism. It is connected via 18a and 18b. Below, the friction mechanism 18a is demonstrated using FIG.
As shown in FIG. 4, the friction mechanism 18a includes a pair of receiving members 19a disposed between the pair of ribs 17a and a biasing member 20a disposed so as to be held between the pair of receiving members 19a. And two friction plates 21a disposed between the pair of ribs 17a and the pair of receiving members 19a, respectively. And a pair of support arm part 12a, a pair of rib 17a, a pair of receiving member 19a, and the friction board 21a are connected by inserting the support pin 22a in each.
　一対の受け部材１９ａは、カップ形状でそれぞれ形成されており、一対の受け部材１９ａは、受け部材１９ａの開口側を互いに対向させることにより内部で付勢部材２０ａを保持している。
　また、付勢部材２０ａは、支持ピン２２ａの周囲を囲うように配置されており、各受け部材１９ａを一対のリブ１７ａに向かって付勢するようになっている。これにより、各摩擦板２１ａが一対のリブ１７ａのそれぞれに押付けられることになり、各受け部材１９ａと各リブ１７ａとの間に摩擦が生じるようになっている。 The pair of receiving members 19a is formed in a cup shape, and the pair of receiving members 19a holds the biasing member 20a inside by making the opening sides of the receiving member 19a face each other.
The urging member 20a is disposed so as to surround the periphery of the support pin 22a, and urges each receiving member 19a toward the pair of ribs 17a.

　なお、本実施形態では、一対の支持アーム部１２ａが振動した際に各受け部材１９ａと各リブ１７ａとの間にかかる力が、最大静止摩擦力を超えないように設定されている。すなわち、一対の支持アーム部１２ａが振動した際には摩擦力によりホルダ３ａが動かず、ホルダ３ａの振動が抑制されることになる。
　一方、一対のホルダ３ａ，３ｂがディスク２を挟む際に各受け部材１９ａと各リブ１７ａとの間にかかる力は、最大静止摩擦力を超えるように設定されている。すなわち、一対のホルダ３ａ，３ｂがディスク２を挟む際には支持アーム部１２ａに対してホルダ３ａが回動軸１１ａを中心に回転するようになっている。
　上述では、図４を用いて摩擦機構１８ａについてのみ説明したが、摩擦機構１８ｂも同様の構成である。摩擦機構１８ｂの構成要素については、図３において摩擦機構１８ａと同様の符号を付して説明を省略する。 In the present embodiment, the force applied between each receiving member 19a and each rib 17a when the pair of support arm portions 12a vibrate is set so as not to exceed the maximum static frictional force. That is, when the pair of support arm portions 12a vibrate, the holder 3a does not move due to the frictional force, and the vibration of the holder 3a is suppressed.
On the other hand, the force applied between each receiving member 19a and each rib 17a when the pair of holders 3a and 3b sandwich the disk 2 is set to exceed the maximum static frictional force. That is, when the pair of holders 3a and 3b sandwich the disk 2, the holder 3a rotates about the rotation shaft 11a with respect to the support arm portion 12a.
In the above description, only the friction mechanism 18a has been described with reference to FIG. 4, but the friction mechanism 18b has the same configuration. The components of the friction mechanism 18b are denoted by the same reference numerals as those of the friction mechanism 18a in FIG.
　また、本実施形態では、図２に示すように、各リブ１７ａ，１７ｂには、ホルダ３ａ，３ｂの回動軸１１ａ，１１ｂを中心として支持ピン２２ａ，２２ｂが移動する軌道に沿って円弧状の切欠き部２３ａ，２３ｂが設けられている。これにより、各ホルダ３ａ，３ｂのパッド８ａ，８ｂがディスク２を挟むと、各支持ピン２２ａ，２２ｂは、各ホルダ３ａ，３ｂが回転する際に干渉しないように切欠き部２３ａ，２３ｂに沿って移動するようになっている。 In the present embodiment, as shown in FIG. 2, each rib 17a, 17b has an arcuate shape along a trajectory along which the support pins 22a, 22b move around the rotation shafts 11a, 11b of the holders 3a, 3b. The notches 23a and 23b are provided. As a result, when the pads 8a and 8b of the holders 3a and 3b sandwich the disk 2, the support pins 22a and 22b follow the notches 23a and 23b so as not to interfere when the holders 3a and 3b rotate. To move.
　このように、本実施形態に係るディスクブレーキ装置１によれば、ホルダ３ａ，３ｂの外側表面９ａ，９ｂには、回動軸１１ａ，１１ｂに対してシリンダ機構５側の位置において一対のリブ１７ａ，１７ｂが設けられ、一対のリブ１７ａ，１７ｂの間には、摩擦機構１８ａ，１８ｂが設けられ、摩擦機構１８ａ，１８ｂは、一対のリブ１７ａ，１７ｂとの間に配置された一対の受け部材１９ａ，１９ｂと、一対の受け部材１９ａ，１９ｂの間で保持されるように配置された付勢部材２０ａと、一対のリブ１７ａ，１７ｂと一対の受け部材１９ａ，１９ｂとの間にそれぞれ配置された一対の摩擦板２１ａ，２１ｂとを備え、一対のリブ１７ａ，１７ｂと一対の受け部材１９ａ，１９ｂと一対の摩擦板２１ａ，２１ｂと一対の支持アーム部１２ａ，１２ｂとが、支持ピン２２ａ，２２ｂをそれぞれに挿通することにより連結されているので、車両の運転中にアーム４ａ，４ｂが振動した場合でも、一対のリブ１７ａ，１７ｂと一対の受け部材１９ａ，１９ｂとの間に摩擦力が働くことによりホルダ３ａ，３ｂがアーム４ａ，４ｂの振動の影響を受けにくくなり、その結果、ホルダ３ａ，３ｂが振動することを抑制することができる。
　また、摩擦機構１８ａ，１８ｂが、一対の受け部材１９ａ，１９ｂと付勢部材２０ａと摩擦板２１ａ，２１ｂとからなる簡易な構成であるので、従来のダンパを設けるような構成に比べて、部品点数が少なく且つ摩擦機構１８ａ，１８ｂ自体の設置スペースも小さくすることができる。 Thus, according to the disc brake device 1 according to the present embodiment, the pair of ribs 17a are provided on the outer surfaces 9a and 9b of the holders 3a and 3b at the position on the cylinder mechanism 5 side with respect to the rotation shafts 11a and 11b. 17b, and friction mechanisms 18a, 18b are provided between the pair of ribs 17a, 17b. The friction mechanisms 18a, 18b are a pair of receiving members disposed between the pair of ribs 17a, 17b. 19a, 19b, an urging member 20a arranged to be held between the pair of receiving members 19a, 19b, and a pair of ribs 17a, 17b and a pair of receiving members 19a, 19b, respectively. A pair of friction plates 21a and 21b, a pair of ribs 17a and 17b, a pair of receiving members 19a and 19b, a pair of friction plates 21a and 21b, and a pair of support arm portions 12a. 12b are connected to each other by inserting the support pins 22a and 22b, so that even if the arms 4a and 4b vibrate during operation of the vehicle, the pair of ribs 17a and 17b and the pair of receiving members 19a and When the frictional force is exerted between the holders 3a and 19b, the holders 3a and 3b are hardly affected by the vibrations of the arms 4a and 4b, and as a result, the holders 3a and 3b can be prevented from vibrating.
Further, since the friction mechanisms 18a and 18b have a simple configuration including a pair of receiving members 19a and 19b, an urging member 20a, and friction plates 21a and 21b, the components are compared with a configuration in which a conventional damper is provided. The number of points is small, and the installation space for the friction mechanisms 18a and 18b itself can be reduced.
　また、摩擦機構１８ａ，１８ｂは、一対のリブ１７ａ，１７ｂとの間に配置された一対の受け部材１９ａ，１９ｂと、一対の受け部材１９ａ，１９ｂの間で保持されるように配置された付勢部材２０ａと、一対のリブ１７ａ，１７ｂと一対の受け部材１９ａ，１９ｂとの間にそれぞれ配置された一対の摩擦板２１ａ，２１ｂとを備えているので、付勢部材２０ａにより摩擦板２１ａが常にホルダ３ａ側に押付けられることなり、一対のリブ１７ａ，１７ｂと一対の受け部材１９ａ，１９ｂとの間に確実に摩擦を発生させることができる。 The friction mechanisms 18a and 18b are attached so as to be held between the pair of receiving members 19a and 19b disposed between the pair of ribs 17a and 17b and the pair of receiving members 19a and 19b. Since the biasing member 20a includes a pair of friction plates 21a and 21b disposed between the pair of ribs 17a and 17b and the pair of receiving members 19a and 19b, the friction plate 21a is provided by the biasing member 20a. It is always pressed against the holder 3a side, and friction can be reliably generated between the pair of ribs 17a, 17b and the pair of receiving members 19a, 19b.
　また、本実施形態に係るディスクブレーキ装置１によれば、各リブ１７ａ，１７ｂには、ホルダ３ａ，３ｂの回動軸１１ａ，１１ｂを中心として支持ピン２２ａ，２２ｂが移動する軌道に沿って円弧状の切欠き部２３ａ，２３ｂが設けられているので、一対のホルダ３ａ，３ｂがディスク２を挟んだ際に切欠き部２３ａ，２３ｂによって支持ピン２２ａ，２２ｂが移動することにより、ホルダ３ａ，３ｂのパッド８ａ，８ｂの表面をディスク２に対して常に一定の距離を開けた状態で平行に保持することができる。これにより、ホルダ３ａ，３ｂのパッド８ａ，８ｂが磨耗した状態でも、ホルダ３ａ，３ｂのパッド８ａ，８ｂの表面がディスクに対して平行な状態で接触することになり、ブレーキ精度の低下を防止することができる。
　また、切欠き部２３ａ，２３ｂを加工する際は、各リブ１７ａ，１７ｂに支持ピン２２ａ，２２ｂの軌道に沿った最小限の加工を行うだけでよく、切欠き全体の構成のコンパクト化を図ることができる。 Further, according to the disc brake device 1 according to the present embodiment, each rib 17a, 17b has a circular shape along a trajectory along which the support pins 22a, 22b move around the rotation shafts 11a, 11b of the holders 3a, 3b. Since the arc-shaped notches 23a and 23b are provided, when the pair of holders 3a and 3b sandwich the disk 2, the support pins 22a and 22b are moved by the notches 23a and 23b. The surfaces of the pads 8a and 8b of 3b can be held parallel to the disk 2 at a constant distance. As a result, even when the pads 8a and 8b of the holders 3a and 3b are worn, the surfaces of the pads 8a and 8b of the holders 3a and 3b are in contact with the disk in a parallel state, thereby preventing a decrease in brake accuracy. can do.
Further, when machining the notches 23a and 23b, the ribs 17a and 17b only need to be minimally worked along the tracks of the support pins 22a and 22b, and the overall structure of the notches can be made compact. be able to.
　また、本実施形態に係るディスクブレーキ装置１によれば、摩擦機構１８ａ，１８ｂが、各ホルダ３ａ，３ｂの回動軸１１ａ，１１ｂに対してシリンダ機構５側に配置されているので、内周締結型のディスク２に対応させるために、各ホルダ３ａ，３ｂの端部６ａ，６ｂをディスク２のボルト２ａと干渉しないように切欠いて形成した場合でも、摩擦機構１８ａ，１８ｂによりホルダ３ａ，３ｂの振動を抑制することができる。 Further, according to the disc brake device 1 according to the present embodiment, the friction mechanisms 18a and 18b are disposed on the cylinder mechanism 5 side with respect to the rotation shafts 11a and 11b of the holders 3a and 3b, so Even when the ends 6a and 6b of the holders 3a and 3b are cut out so as not to interfere with the bolts 2a of the disk 2 in order to correspond to the fastening type disk 2, the holders 3a and 3b are formed by the friction mechanisms 18a and 18b. Can be suppressed.

　以下、本発明の第２実施形態に係るディスクブレーキ装置を、図面を参照しながら説明する。
　図５は、本発明の第２実施形態に係るディスクブレーキ装置１を側面から見た図であり、図６は、本発明の第２実施形態に係るディスクブレーキ装置１を上方から見た図である。ここで、第１実施形態と同様の構成要素については同じ符号を付し、説明を省略する。 [Second Embodiment]
Hereinafter, a disc brake device according to a second embodiment of the present invention will be described with reference to the drawings.
FIG. 5 is a side view of the disc brake device 1 according to the second embodiment of the present invention, and FIG. 6 is a diagram of the disc brake device 1 according to the second embodiment of the present invention viewed from above. is there. Here, the same components as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted.
　図５に示すように、本実施形態のディスクブレーキ装置１においては、第１実施形態と異なり、ディスク２が、ディスク２の内周以外の位置で車輪とボルト（図示せず）により締結されている。そのため、各ホルダ３ａ，３ｂは、矩形形状で形成されている。
　また、図６に示すように、各支持アーム部１２ａ，１２ｂのホルダ側端部１３ａ，１３ｂは、回動軸１１ａ，１１ｂに対してシリンダ機構５と反対方向に延びる延長部３０ａ，３０ｂを備えている。 As shown in FIG. 5, in the disc brake device 1 of the present embodiment, unlike the first embodiment, the disc 2 is fastened by wheels and bolts (not shown) at positions other than the inner periphery of the disc 2. Yes. Therefore, each holder 3a, 3b is formed in a rectangular shape.
Further, as shown in FIG. 6, the holder side end portions 13a and 13b of the support arm portions 12a and 12b include extension portions 30a and 30b extending in the opposite direction to the cylinder mechanism 5 with respect to the rotation shafts 11a and 11b. ing.
　以下では、図６を用いてホルダ３ａ側の構成について説明する。
　図６に示すように、ホルダ３ａの外側表面９ａには、回動軸１１ａに対してシリンダ機構５と反対側の位置において一対のリブ３１ａが設けられている。これら一対のリブ３１ａは、一対の支持アーム部１２ａの延長部３０ａ，３０ｂの間に配置されている。 Below, the structure by the side of the holder 3a is demonstrated using FIG.
As shown in FIG. 6, a pair of ribs 31a is provided on the outer surface 9a of the holder 3a at a position opposite to the cylinder mechanism 5 with respect to the rotating shaft 11a. The pair of ribs 31a is disposed between the extension portions 30a and 30b of the pair of support arm portions 12a.
　本実施形態では、一対のリブ３１ａの間には摩擦機構１８ａが設けられており、一対の支持アーム部１２ａの延長部３０ａと一対のリブ３１ａとは、摩擦機構１８ａを介して連結されている。詳しくは、一対の支持アーム部１２ａの延長部３０ａと一対のリブ３１ａと一対の受け部材１９ａと摩擦板２１ａとは、支持ピン２２ａをそれぞれに挿通することによりに連結されている。 In the present embodiment, a friction mechanism 18a is provided between the pair of ribs 31a, and the extension portions 30a of the pair of support arm portions 12a and the pair of ribs 31a are connected via the friction mechanism 18a. . In detail, the extension part 30a of a pair of support arm part 12a, a pair of rib 31a, a pair of receiving member 19a, and the friction board 21a are connected by inserting the support pin 22a through each.
　付勢部材２０ａは、支持ピン２２ａの周囲を囲うように配置されており、各受け部材１９ａを一対のリブ３１ａのそれぞれに向かって付勢するようになっている。これにより、各摩擦板２１ａが一対のリブ３１ａのそれぞれに押付けられることになり、各受け部材１９ａと各リブ３１ａとの間に摩擦が生じるようになっている。
　上述では、図６を用いてホルダ３ａ側の構成についてのみ説明したが、ホルダ３ｂ側も同様の構成である。 The urging member 20a is disposed so as to surround the support pin 22a, and urges each receiving member 19a toward each of the pair of ribs 31a. Thereby, each friction plate 21a is pressed against each of the pair of ribs 31a, and friction is generated between each receiving member 19a and each rib 31a.
In the above description, only the configuration on the holder 3a side has been described with reference to FIG. 6, but the configuration on the holder 3b side is also the same.
　また、図６に示すように、本実施形態では、各支持アーム部１２ａ，１２ｂの延長部３０ａ，３０ｂには、ホルダ３ａ，３ｂの回動軸１１ａ，１１ｂを中心として支持ピン２２ａ，２２ｂが移動する軌道に沿って円弧状の切欠き部３２ａ，３２ｂが設けられている。ここで、図６に示すように、本実施形態の切欠き部３２ａ，３２ｂは、第１実施形態の切欠き部２３ａ，２３ｂとは円弧の向きが逆になっている。これにより、各ホルダ３ａ，３ｂのパッド８ａ，８ｂがディスク２を挟むと、各支持ピン２２ａ，２２ｂは、各ホルダ３ａ，３ｂが回転する際に干渉しないように切欠き部３２ａ，３２ｂに沿って移動するようになっている。 As shown in FIG. 6, in the present embodiment, support pins 22a and 22b are provided around the rotation shafts 11a and 11b of the holders 3a and 3b on the extension portions 30a and 30b of the support arm portions 12a and 12b. Arc-shaped notches 32a and 32b are provided along the moving track. Here, as shown in FIG. 6, the cutout portions 32 a and 32 b of the present embodiment have an arc direction opposite to that of the cutout portions 23 a and 23 b of the first embodiment. As a result, when the pads 8a and 8b of the holders 3a and 3b sandwich the disk 2, the support pins 22a and 22b extend along the notches 32a and 32b so as not to interfere when the holders 3a and 3b rotate. To move.
　このように、本実施形態に係るディスクブレーキ装置１によれば、支持アーム部１２ａのホルダ側端部１３ａは、回動軸１１ａに対してシリンダ機構５と反対方向に延びる延長部３０ａを備え、ホルダ３ａの外側表面９ａには、回動軸１１ａに対してシリンダ機構５と反対側の位置において一対のリブ３１ａが設けられ、一対のリブ３１ａの間に摩擦機構１８ａが設けられ、一対のリブ３１ａと一対の受け部材１９ａと一対の摩擦板２１ａと一対の支持アーム部１２ａの延長部３０ａとが、支持ピン２２ａをそれぞれに挿通することにより連結されているので、車両の運転中にアーム４ａが振動した場合でも、一対のリブ３１ａと一対の受け部材１９ａとの間に摩擦力が働くことによりホルダ３ａがアーム４ａの振動の影響を受けにくくなり、その結果、ホルダ３ａが振動することを抑制することができる。
　また、摩擦機構１８ａ，１８ｂが、一対の受け部材１９ａ，１９ｂと付勢部材２０ａと摩擦板２１ａ，２１ｂとからなる簡易な構成であるので、従来のダンパを設けるような構成に比べて、部品点数が少なく且つ摩擦機構１８ａ，１８ｂ自体の設置スペースも小さくすることができる。 Thus, according to the disc brake device 1 according to the present embodiment, the holder side end portion 13a of the support arm portion 12a includes the extension portion 30a extending in the direction opposite to the cylinder mechanism 5 with respect to the rotation shaft 11a, A pair of ribs 31a is provided on the outer surface 9a of the holder 3a at a position opposite to the cylinder mechanism 5 with respect to the rotation shaft 11a, and a friction mechanism 18a is provided between the pair of ribs 31a. 31a, the pair of receiving members 19a, the pair of friction plates 21a, and the extended portions 30a of the pair of support arm portions 12a are connected to each other by inserting the support pins 22a. Even when the holder 3a vibrates, the holder 3a becomes less susceptible to the vibration of the arm 4a due to the frictional force acting between the pair of ribs 31a and the pair of receiving members 19a. As a result, it is possible to prevent the holder 3a vibrates.
Further, since the friction mechanisms 18a and 18b have a simple configuration including a pair of receiving members 19a and 19b, an urging member 20a, and friction plates 21a and 21b, the components are compared with a configuration in which a conventional damper is provided. The number of points is small, and the installation space for the friction mechanisms 18a and 18b itself can be reduced.
　また、本実施形態に係るディスクブレーキ装置１によれば、支持アーム部１２ａ，１２ｂの延長部３０ａ，３０ｂには、ホルダ３ａ，３ｂの回動軸１１ａ，１１ｂを中心として支持ピン２２ａ，２２ｂが移動する軌道に沿って円弧状の切欠き部３２ａ，３２ｂが設けられているので、一対のホルダ３ａ，３ｂがディスク２を挟んだ際に切欠き部３２ａ，３２ｂによって支持ピン２２ａ，２２ｂが移動することにより、ホルダ３ａ，３ｂのパッド８ａ，８ｂの表面をディスク２に対して常に一定の距離を開けた状態で平行に保持することができる。これにより、ホルダ３ａ，３ｂのパッド８ａ，８ｂが磨耗した状態でも、ホルダ３ａ，３ｂのパッド８ａ，８ｂの表面がディスクに対して平行な状態で接触することになり、ブレーキ精度の低下を防止することができる。 Further, according to the disc brake device 1 according to the present embodiment, the support pins 22a and 22b are centered on the rotation shafts 11a and 11b of the holders 3a and 3b on the extension portions 30a and 30b of the support arm portions 12a and 12b. Since the arc-shaped notches 32a and 32b are provided along the moving track, the support pins 22a and 22b are moved by the notches 32a and 32b when the pair of holders 3a and 3b sandwich the disk 2. By doing so, the surfaces of the pads 8a and 8b of the holders 3a and 3b can be held parallel to the disk 2 at a constant distance. As a result, even when the pads 8a and 8b of the holders 3a and 3b are worn, the surfaces of the pads 8a and 8b of the holders 3a and 3b are in contact with the disk in a parallel state, thereby preventing a decrease in brake accuracy. can do.
　以上、本発明の実施の形態につき述べたが、本発明は既述の実施形態に限定されるものでなく、本発明の技術的思想に基づいて各種の変形及び変更が可能である。 Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications and changes can be made based on the technical idea of the present invention.
　上述の第２実施形態では、各支持アーム部１２ａ，１２ｂの延長部３０ａ，３０ｂに切欠き部３２ａ，３２ｂを設けているが、第１実施形態と同様に、切欠き部３２ａ，３２ｂを各リブ３１ａに設けるようにしてもよい。 In the second embodiment described above, the notches 32a and 32b are provided in the extended portions 30a and 30b of the support arm portions 12a and 12b. However, as in the first embodiment, the notches 32a and 32b are provided in the respective extensions. You may make it provide in the rib 31a.
　本発明は、部品点数が少なく且つ設置スペースも小さい構成で制輪子の振動を抑制するとともに、制輪子が磨耗した状態でもブレーキ精度を維持することが可能なディスクブレーキ装置を提供することができる。 The present invention can provide a disc brake device that can suppress the vibration of the brake with a configuration having a small number of parts and a small installation space, and can maintain the brake accuracy even when the brake is worn.
