Description

Technical Field

[0001] This utility model relates to the field of brake technology, and in particular to a pad brake. Background Technology

[0002] Currently available electromagnetic clutches or brakes, whether square or round, primarily consist of a stationary plate with a coil and a moving plate that engages with the stationary plate when energized. The mechanical force overcomes by the electromagnetic force is the spring force embedded in the stationary or moving plate. Conventional stationary plate materials include pure iron, steel plates, or steel bars. This requires the stationary plate to possess both good electromagnetic and mechanical properties. Pure iron has good electromagnetic properties but poor mechanical properties, while steel plates have good mechanical properties but poor electromagnetic properties; it is difficult to achieve both simultaneously with a single material. Therefore, there is an urgent need for a stamped brake that is easy to mass-produce, simple to process, and where the stationary plate only needs to bear mechanical forces. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and to provide a punch brake that is easy to mass-produce, simple to process, and whose stationary plate only needs to bear mechanical force.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0005] A ply brake includes a moving plate, a stationary plate, an iron core, and a coil. The iron core is composed of multiple layers of plywood. The iron core is fixedly disposed on both sides of the stationary plate. An annular groove for the coil to be inserted is provided on one side of the stationary plate and the iron core on the same side. The moving plate is disposed between the stationary plate and a brake liner for braking, and there is a gap between the moving plate and the stationary plate. The moving plate has a protrusion in the middle, which is inserted into a hole in the center of the stationary plate. An adjusting nut is provided on the side of the protrusion that protrudes from the stationary plate. Blind holes are symmetrically provided on the side of the stationary plate facing the moving plate. A spring is provided in each blind hole to abut against the moving plate. The other side of the moving plate is used to cooperate with the brake liner.

[0006] Furthermore, all the laminations are of E-type structure, and two transverse grooves can be formed on the iron core formed by stacking multiple laminations. The side of the stationary plate is provided with a vertical groove that communicates with the transverse grooves, corresponding to the iron core on the same side.

[0007] Compared with the prior art, the present invention has the following beneficial effects:

[0008] In this invention, the stationary plate only needs to withstand mechanical force, and the coil is set in the annular slot formed by the stationary plate and the iron core. This eliminates the need for the stationary plate to possess electromagnetic properties, allowing for the selection of higher-strength materials and resulting in a more optimized overall structure. It is easy to mass-produce, as the stationary plate does not require machining grooves and lead-out slots for the coil, simplifying machining and ultimately reducing the overall manufacturing cost of the brake. Simultaneously, it offers superior performance and high reliability. Attached Figure Description

[0016] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0017] like Figure 1 and Figure 2 As shown, a ply brake includes a moving plate 1, a stationary plate 2, an iron core 4, and a coil 5. The iron core 4 is composed of multiple layers of plywood 12. The iron core 4 is fixedly disposed on both sides of the stationary plate 2. An annular groove for the coil 5 to be fitted is provided on one side of the stationary plate 2 and the iron core 4 on the same side. The moving plate 1 is disposed between the stationary plate 2 and the brake liner 3 for braking, and there is a gap between the moving plate 1 and the stationary plate 2. The moving plate 1 has a protrusion 10 in the middle. The protrusion 10 is inserted into the hole in the center of the stationary plate 2, and an adjusting nut is provided on one side of the protrusion 10 that protrudes from the stationary plate 2. Blind holes are symmetrically provided on the side of the stationary plate 2 facing the moving plate 1. A spring 11 is provided in each blind hole to abut against the moving plate 1. The other side of the moving plate 1 is used to cooperate with the brake liner 3.

[0018] The laminations 12 are all E-shaped structures. Two transverse grooves can be formed on the iron core 4, which is formed by stacking multiple laminations 12. The side of the stationary plate 2 is provided with a vertical groove corresponding to the iron core 4 on the same side, communicating with the transverse grooves. The transverse grooves of the iron core 4 and the vertical grooves of the stationary plate 2 together form a rectangular annular slot, facilitating the assembly of the coils 5.

[0019] In this invention, the static plate 2 only needs to withstand mechanical force, and a material with better strength can be selected to make the overall structure more optimized and the structural strength higher.

[0020] like Figure 3 As shown, when used in a caliper brake, the stationary plate 2 can be integrated with the caliper body 6. An adjustable brake liner 7 is located on the other side of the caliper body 6, and a brake liner 3 that cooperates with the brake disc 8 is provided on the moving plate 1. When the brake is de-energized, the moving plate 1 maintains a gap with the stationary plate 2 due to the elastic force of the spring 11, allowing the brake liner 3 to move in coordination with the adjustable brake liner 7 to brake the brake disc 8. When the brake is energized, the moving plate 1 moves towards the stationary plate 2 due to the attraction of the iron core 4, thereby disengaging the brake liner 3 from the brake disc 8.

[0021] like Figure 4 As shown, when used in a shaft-type brake, the brake liner 3 is fixed to the drive shaft 9. When the brake is de-energized, the moving plate 1 maintains a gap with the stationary plate 2 due to the elastic force of the spring 11, and the surface of the moving plate 1 contacts the brake liner 3 to brake the drive shaft 9. When the brake is energized, the moving plate 1 moves towards the stationary plate 2 due to the attraction of the iron core 4, thereby disengaging the moving plate 1 from the brake liner 3.

[0022] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
