せる。 An electromagnetic brake is, for example, a safety brake for a vehicle, that is, when the brake pedal is depressed for a certain period of time, the brake pedal is held in that position, and then when the vehicle starts moving, the brake is released. used for The basic structure of such an electromagnetic brake is shown in FIG. Electromagnetic brake 1
has a shaft 2 connected to a brake pedal (not shown) via a link, and this shaft 2 is held on a support shaft 4 via a one-way clutch 3. The one-way clutch 3 allows the shaft 2 to rotate in the direction in which the brake pedal is depressed, but allows the shaft 2 to rotate in the opposite direction only together with the support shaft 4.
When the rotation of the shaft 2 is prevented, there is no rotation of the shaft 2 in this direction. A magnetic yoke 6 is attached to the support shaft 4 via a bearing 5. A coil 8 is wound around the yoke 6 using a non-magnetic bobbin 7.
A plate 9 is arranged facing and spaced apart from the yoke 6, and a rod 10 fixed to the plate 9 is slid into a hole drilled in a support shaft 4, so that the plate 9 is held by the support shaft 4. plate 9
is constantly separated from the yoke 6 by the leaf spring 11.

フト４と共に回動し、ブレーキペダルはリターン
スプリングの附勢力により元位置に復帰する。 In the electromagnetic brake 1 having the above configuration, when the brake pedal is depressed for a certain period of time, a magnetic force is generated in the yoke 6 by energizing the coil 8, and the plate 9 is pulled into the leaf spring 1.
The upper surface of the yoke 6 resists the auxiliary force of 1 and is attracted to the upper surface of the yoke 6,
Rotation of the support shaft 4 is prevented. The one-way clutch 5 causes the shaft 2 to stop the movement of the brake pedal in the release direction (brake release direction), and the brake pedal remains in a fixed position and the braking state continues. On the other hand, when the vehicle shifts to driving state (for example, when the accelerator pedal is depressed),
The coil 8 is de-energized, the plate 9 is separated from the yoke 6 by the spring force of the leaf spring 11, and the support shaft 4 becomes freely rotatable together with the plate 9. Therefore, the shaft 2 rotates together with the support shaft 4, and the brake pedal returns to its original position due to the biasing force of the return spring.

ねの附勢力を調整し、プレートのヨークへの当た
りを小さくし音の発生を防止させている。 Since such an electromagnetic brake causes the plate to be attracted to the yoke as described above, it generates a hitting sound when the plate hits the yoke. Vehicles are always desired to be quiet, and the banging noise gives the driver a sense of discomfort. For this reason, the electromagnetic brake shown in FIG. 1 adjusts the biasing force of the leaf spring to reduce the contact between the plate and the yoke, thereby preventing the generation of noise.

音の問題が解消される。 This idea uses an elastic material spacer in addition to the technical means of adjusting the biasing force of the leaf spring in order to eliminate the hammering noise generated in the electromagnetic brake.Basically, the idea is to use an elastic material spacer. A technical means is used in which a plate of elastic material is interposed between the two. The spacer is in contact with the plate, and when a suction force is applied to the plate, the plate elastically deforms the spacer and is attracted to the yoke, reducing the initial contact force between the plate and yoke and eliminating the problem of hitting noise.

この考案によれば、プレートを弾性材スペーサ

がなく、又、プレートのガタ付きもない。 According to this invention, since the plate is always in contact with the elastic material spacer, the gap between the plate and the yoke can be easily maintained. Therefore, assembly is easy, and in addition, even if the plate is subjected to vibration, the spacer absorbs this vibration, so that the plate does not hit the yoke, and there is no rattling of the plate.
この考案の実施例を第２図を参照して説明す

第１図に記した符号と同符号を記し、その説明を
省略する。 An embodiment of this invention will be described with reference to FIG. Note that the configuration shown in Figure 1 has the same configuration as the one shown in Figure 1.
The same reference numerals as those shown in FIG. 1 are used, and the explanation thereof will be omitted.

よつてサポートシヤフト４の頂面に着座する。 The top surface of the support shaft 4 is located inward from the top surface of the yoke 6, a space is created between the plate 9 and the top surface of the support shaft 4, and a circular elastic material spacer 12 made of synthetic rubber or the like is inserted into this space. Arrange in space. The spacer 12 has a rim 13 that bulges upward around the spacer, and the upper end of the rim 13 is connected to the plate 9.
touches the bottom surface of The spacer 12 is seated on the top surface of the support shaft 4 by its back plate 14.

にもどる。 When the coil 8 is energized and magnetic force is generated in the yoke 6, the plate 9 is attracted to the yoke 6. At this time, the plate 9 moves toward the top surface of the yoke 6 while elastically deforming the rim 13 of the spacer 12. This elastic deformation of the rim 13 weakens the impact force when the plate 9 is attracted to the yoke 6, and no hitting noise is generated. When the coil 8 is de-energized and the magnetic force of the yoke 6 disappears, the rim 1 of the elastic material spacer 12
Due to the restoring force of 3, the plate 9 returns to the original position shown.
