- the brake shoe 30 is fixed to the brake shoe support plate 40, and the brake shoe support plate 40 can move in the axial direction and cannot rotate about the axis. Therefore, when the motor 1 is driven, the rotation of the rotation shaft 15 can be braked without the brake shoe 30 rotating with the rotation of the rotation shaft 15 and the brake plate 20. When the drive of the motor 1 is stopped, the rotation of the rotary shaft 15 can be quickly stopped by the braking force by the brake shoe 30. At the time of this stop, a fixed holding force is obtained with respect to the rotating shaft 15. In this way, a braking action during driving and a holding torque during stopping are obtained.
- An annular brake shoe 30 capable of ensuring a sliding contact area is brought into sliding contact with the brake plate 20 to prevent the brake shoe 30 from rotating together with the brake plate 20. Therefore, the rotational moment due to the frictional force of the brake shoe 30 can be suppressed, and the spring constant of the coupled portion of the brake shoe 30 and the brake plate 20 can be prevented from changing.
- the first term on the right side represents a restoring force that generates a simple vibration, and this coefficient is a spring constant generally referred to. Since the tilt angle ⁇ is included in the term after the second term, according to the related art shown in FIG. 6, the same effect as that in which the spring constant is changed is generated.
- the self-excited vibration of the brake shoe 30 is suppressed, and abnormal noise called squealing of the brake is generated. Can be reduced.
- equation (7) The effect of reducing the occurrence of abnormal noise will be described in relation to equation (7). Since it is difficult to handle the three-variable expression (7) as it is, determination of stability is considered with two variables with reduced elements. Suppose the equation can be expressed as: In this equation, it is known that when the product of non-diagonal elements is negative, a self-excited vibration system is obtained.
- the brake shoe 30 is annular, it is possible to secure a sliding contact area, so that the brake shoe 30 can be prevented from rotating together with the brake plate 20. That is, unlike the prior art shown in FIG. 6, the tilt angle ⁇ is zero or infinitely close to zero.
- equation (7) considering the part excluding the equation of motion for brake shoe rotation, In equation (9), the product of the two off-diagonal elements is positive and does not form a self-excited vibration system. Therefore, according to the above embodiment, it is possible to reduce the occurrence of abnormal brake sound.
- the tilt angle ⁇ is generated, so it is included in the non-diagonal element Can take both positive and negative values. Therefore, the product of two off-diagonal elements may be negative. That is, according to the prior art, self-excited vibration is generated, and there is a possibility that abnormal noise of the brake is generated.
- the brake shoe 30 gradually wears due to friction with the brake plate 20, and the axial thickness of the brake shoe 30 decreases. With this decrease, the brake shoe support plate 40 receiving the urging force of the conical coil spring 50 moves to the brake plate 20 side. The brake shoe support plate 40 eventually hits the stopper 10c, and further movement toward the brake plate 20 is restricted by the stopper 10c. As the wear of the brake shoe 30 further progresses, the brake shoe 30 does not come into sliding contact with the brake plate 20. Therefore, it is possible to suppress the occurrence of sparks due to sliding contact in a state where wear has progressed to some extent.
- the above-described restriction is not necessary, and the conical coil spring has a free height that allows a sufficient biasing force to be obtained until the brake shoe support plate 40 hits the stopper part 10c. 50 can be selected. Therefore, a stable braking force can be obtained until the brake shoe support plate 40 contacts the stopper 10c.
- the brake plate 104 is provided on the inner side in the axial direction when viewed from the non-output side bearing 106b.
- the brake shoe 105 is disposed on the radially outer side of the counter-output side bearing 106b so as not to interfere with the counter-output side bearing 106b. Accordingly, the outer diameter of the brake plate 104 becomes relatively large. That is, the brake shoe 105 comes into sliding contact with the brake plate 104 at a position relatively away from the axis of the rotating shaft 103. Inevitably, the peripheral speed of the sliding contact portion is relatively high.
- the amount of wear of the brake shoe is proportional to the value of the product PV of the contact pressure P [MPa] generated by the spring biasing force F and the peripheral speed V [m / s] on the sliding contact surface of the brake shoe.
- the peripheral speed V is greater than a certain value, the wear amount is large regardless of P. As a result, it is difficult to extend the braking force life in FIG.
- the outer diameter of the brake plate 20 and the outer diameter of the brake shoe 30 are both smaller than the outer diameter of the non-output-side bearing 14. Therefore, the slidable contact portion is relatively close to the axial center of the rotating shaft 15, and an increase in the peripheral speed V at the slidable contact portion can be suppressed.
- the brake shoe 30 is annular and the sliding contact area is secured. , P can also be suppressed. As a result, the value of the product PV can be reduced and the life of the braking force can be extended.
- conical coil spring 50 instead of the conical coil spring 50, an arbitrary urging mechanism such as a normal coil spring or an elastic mechanism may be provided.
- the second hole portion 40c may be an engaging portion that engages with the convex portion 30c, and any of a shape that protrudes from the support surface of the brake shoe support plate 40 to the opposite surface and a shape that is recessed without protruding. Good. Furthermore, the convex portion 30 c may be provided in the brake shoe support plate 40, and the second hole portion 40 c may be provided in the brake shoe 30.
- the brake shoe support plate 40 is not limited to the bearing housing portion 10a that is a fixed portion in the motor 1 that does not move even when the motor 1 is driven, and may be engaged with another fixed portion.
- the friction brake structure can be provided in a rotating electric machine other than the motor 1.

Abstract
Description
このように、環状のブレーキシューをブレーキ板に摺接させ、かつブレーキシューがブレーキ板とともに回転しないようにしたことにより、ブレーキシューの摩擦力による回転モーメントを抑制し、ブレーキシューとブレーキ板の連成部のばね定数を変化させないようにすることができる。その結果、ブレーキシューの自励振動を抑制し、ブレーキの鳴きと呼ばれる異常音の発生を低減することができる。
発明者はまず、異常音の発生原理に関して検討を行った。以下に詳細を説明する。
摩擦ブレーキ構造における異常音は、連成系の自励振動に分類される現象である。ブレーキ板104の一部分とブレーキシュー1052とコイルスプリング109とを含む連成系を、図1の矢印Yの方向から見た様子を図2に示している。同図におけるブレーキ板104の弾性をkBとし、ブレーキ板104の質量をmBとし、ブレーキ板104の位置をxBとする。また、ブレーキシュー1052の弾性をkとし、ブレーキシュー1052の質量をmSとし、ブレーキシュー1052の位置をxSとする。さらに、コイルスプリング109の弾性をkSとする。同図におけるφは、ブレーキ板104が回転し、ブレーキ板104の一部分が矢印A2の方向に移動したことによるブレーキシュー1052の倒れ角を示している。加えて、ブレーキシュー1052の慣性モーメントをJSとし、ブレーキ板104とブレーキシュー1052の摩擦係数をμとし、ブレーキシュー1052の重心Gから摺接面105aまでの距離をl0とし、時間をtとする。また、ブレーキ板104とブレーキシュー1052の接触面積をAとし、ブレーキシュー1052の重心G周りの回転に関するばね定数をkφとする。平衡点近傍でのこれらの量の間には次の関係が成り立つ。
これまでに述べた異常音の発生原理を踏まえて、本発明の一実施形態を以下に説明する。
上述したように、ブレーキシュー30はブレーキシュー支持板40に固定されており、該ブレーキシュー支持板40は軸方向に移動可能かつ軸周りに回転不可能とされている。そのため、モータ1の駆動時は、回転軸15及びブレーキ板20の回転に伴ってブレーキシュー30が回転してしまうことなく、回転軸15の回転を制動することができる。モータ1の駆動を停止させると、ブレーキシュー30による制動力により、迅速に回転軸15の回転を止めることができる。この停止時においては回転軸15に関し一定の保持力が得られる。このように、駆動時における制動作用及び停止時における保持トルクが得られる。
ここで、連成振動を表す式(4)~(6)の各々において、右辺第1項は単振動を発生させる復元力を表現しており、この係数が一般に言われるばね定数である。第2項より後の項に倒れ角φが含まれていることにより、図6に示した従来技術によれば、ばね定数が変化したことと同じ効果が発生する。
上記実施形態によれば、ブレーキシュー30とブレーキ板20の連成部のばね定数を変化させないようにすることで、ブレーキシュー30の自励振動を抑制し、ブレーキの鳴きと呼ばれる異常音の発生を低減することができる。
円錐コイルばね50に代えて、通常のコイルばねなどの任意の付勢機構あるいは弾撥機構を設けてもよい。
