Description

Technical Field

[0001] The present invention relates to a disc brake, in particular to a direct-push release electromagnetic caliper disc brake. Background Art

[0002] Caliper disc brakes are typically hydraulically actuated, resulting in a relatively complex structure and a large footprint, making them suitable only for applications with larger installation spaces. For applications with smaller installation spaces, electromagnetic caliper disc brakes, driven by electromagnets, are the only viable option. A major issue with electromagnetic caliper disc brakes is their inability to properly grip the brake disc during braking, causing eccentric wear of the brake shoe. Overheating from this eccentric wear affects braking performance. This inability to properly grip the brake disc occurs because the release electromagnet on an electromagnetic caliper disc brake pushes the left brake arm to release the brake. Therefore, it is mounted on the upper, outer side of the right brake arm. Both the front and right brake arms of a caliper disc brake are connected to the base via an articulated shaft. This inevitably causes the right brake arm to become misaligned under normal conditions due to the weight of the arm. Consequently, eccentric wear of the brake shoe is unavoidable with electromagnetic caliper disc brakes. Summary of the Invention

[0003] The purpose of the present invention is to provide a direct-push release electromagnetic caliper disc brake without eccentric wear, so as to solve the problem of eccentric wear of brake shoes caused by the unbalanced weight of the right brake arm in the existing electromagnetic caliper disc brake.

[0004] The object of the present invention is achieved as follows: a direct-push release electromagnetic caliper disc brake, comprising a left brake arm, a right brake arm, a release electromagnet and a brake spring, the release electromagnet being fixedly connected to the top mounting seat of the right brake arm, a horizontal and vertical section corresponding to the release electromagnet being provided at the upper end of the left brake arm, a release push rod being installed on the horizontal and vertical section, an electromagnetic push rod connected to the armature being provided in the release electromagnet, and the end of the electromagnetic push rod being opposite to the end of the release push rod.

[0005] Furthermore, straight arm sections close to each other are respectively provided at the lower sections of the left brake arm and the right brake arm, and brake shoes are respectively hinged on the straight arm sections on the left brake arm and the right brake arm. The brake shoes on the two brake arms are opposite to each other to form a braking part that clamps the brake disc.

[0006] Furthermore, the lower ends of the left brake arm and the right brake arm are respectively hinged to the connecting ear of the base through a lower hinge shaft.

[0007] Furthermore, two front and rear connecting blocks are connected to the horizontal and vertical sections, the release push rod passes through the through holes on the two connecting blocks, and is provided with exposed ends on the outside of the two connecting blocks, and tubular washers are respectively connected to the exposed ends, and are fixed by release adjusting nuts.

[0008] Furthermore, the brake spring is located in the spring box, and a spring pad is provided at one end of the spring box to position and support the right end of the brake spring. The other end of the spring box is connected to the left brake arm through the left hinge shaft, and the left end of the brake spring is positioned and supported by the spring nut; an adjusting screw is passed through the brake spring, the left end of the adjusting screw is screwed on the spring nut, and the right end of the adjusting screw passes through the spring box and the right hinge shaft, and is locked on the right hinge shaft by the brake adjusting nut.

[0009] By providing a horizontal section at the upper end of the left brake arm and positioning a release push rod there, the present invention allows the release electromagnet to be smoothly installed on top of the right brake arm. This minimizes the unbalanced weight of the right brake arm and avoids the normal displacement of the right brake arm due to the unbalanced weight. This effectively reduces or even eliminates the phenomenon of uneven wear of the brake shoe of the electromagnetic caliper disc brake. The separate arrangement of the release push rod and the electromagnetic push rod facilitates the adjustment of the brake release force.

[0010] The direct-push release electromagnetic caliper disc brake of the present invention has a simple structure, is easy to adjust, and is convenient to install. Compared with a hydraulically driven caliper disc brake, the occupied space can be reduced by more than half, and the scope of application is expanded. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] like Figure 1 、 Figure 2As shown, the left and right brake arms 1 and 15 are each connected to a base 18 via a lower hinge shaft 17. The lower sections of the left and right brake arms 1 and 15 are each provided with adjacent straight arm sections, each hinged with a brake shoe 16. The brake shoes 16 on each arm face each other, forming the braking portion that clamps the brake disc. The top of the right brake arm 15 is formed into a mounting seat, and the release electromagnet 11 is fixed to the top mounting seat of the right brake arm 15. The upper end of the left brake arm 1 extends upward and curves to the right, forming a horizontal section. The centerline of this section is at the same height as the axis of the release electromagnet 11. This section is connected to two juxtaposed and spaced connection blocks 6. A through-hole is provided at the center of each connection block 6, through which the release push rod 9 passes. The release push rod 9 has threads on both ends, each of which protrudes from the exterior of the adjacent connection block 6, forming an exposed end. Tubular washers 4 are inserted into the two exposed ends of the release push rod 9 and secured by a release adjustment nut 5. An electromagnetic push rod 10, connected to the armature, is located within the release electromagnet 11. The end of the electromagnetic push rod 10 faces the end of the release push rod 9, pushing the release push rod to release the brake. The release adjustment nut 5 allows the fore-and-aft position of the release push rod 9 to be adjusted, thereby adjusting the brake release force.

[0015] The brake spring 8 is located within the spring case 2. A spring washer is located at the right end of the spring case 2 to position and support the right end of the brake spring 8. The left end of the spring case 2 is connected to the left brake arm 1 via the left hinge shaft 3. The left end of the brake spring 8 is positioned and supported by the spring nut 7. An adjustment screw 14 extends through the brake spring 8. The left end of the adjustment screw 14 is threaded onto the spring nut 7. The right end of the adjustment screw 14 passes through the spring case 2 and the right hinge shaft 12, and is locked to the right hinge shaft 12 by the brake adjustment nut 13. The spring nut 7 is equipped with a bayonet that engages with the upper and lower surfaces of the spring case 2, creating a sliding connection. By adjusting the brake adjustment nut 13, the compression of the brake spring 8 can be adjusted, thereby adjusting the braking force of the brake.
