Description

Technical Field

[0001] The invention relates to the field of tricycle brake components, and in particular to a brake box connecting device for a tricycle brake. Background Art

[0002] The brake is a device that has the function of slowing down, stopping or keeping the moving parts (or moving machinery) stopped. It is a mechanical part that stops or slows down the moving parts in the machinery. Commonly known as brakes or gates. The brake is mainly composed of a frame, brake parts and operating devices. Some brakes are also equipped with automatic adjustment devices for the clearance of brake parts. In order to reduce the braking torque and structural size, the brake is usually installed on the high-speed shaft of the equipment, but large equipment with higher safety requirements (such as mine hoists, elevators, etc.) should be installed on the low-speed shaft close to the working part of the equipment.

[0003] The brake is an important component in the braking system of an electric tricycle, and the brake box is one of the important parts of the brake.

[0004] The traditional brake box connecting device is directly connected to the brake pad without any limit, and the brake pad is prone to fall off or misalignment when the road is bumpy during driving. At the same time, the existing brake adopts a single rocker arm linkage method, which has weak braking strength and poor effect. Summary of the invention

[0021] In the following description, a large number of specific details are provided to provide a more thorough understanding of the present invention. However, it is apparent to those skilled in the art that the present invention can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present invention, some technical features well known in the art are not described.

[0022] The applicant believes that the traditional brake box connecting device is directly connected to the brake pad without any limit, and the brake pad is prone to fall off or misalignment when the road is bumpy during driving. At the same time, the existing brake adopts a single rocker arm linkage, which has weak braking strength and poor effect.

[0023] To this end, the applicant designed a brake box 1 linkage device for a tricycle brake, which can limit the brake pads through the bushing 5 and cam 6, avoiding the brake pads from falling or dislocating when the road is bumpy, effectively improving the braking reliability. At the same time, the multi-rocker design can play a force-enhancing effect, effectively improving the overall braking force, and thus improving the overall braking effect.

[0024] The brake box linkage device for tricycle brakes of the present invention mainly comprises three components: a brake box 1, a multi-rocker arm structure and a brake cam 6 structure. The brake box 1 has a predetermined operating area and size, and can perform corresponding load-bearing and position-limiting operations; the multi-rocker arm structure is rotatably connected to the brake box 1, and can perform a rotation adjustment operation within a predetermined range; the brake cam 6 structure is rotatably connected to the brake box 1, and can perform a rotation adjustment operation within a predetermined range, and the brake cam 6 structure is eccentrically arranged.

[0025] The multi-rocker structure includes three components: a first rocker arm 2, a second rocker arm 3 and a transmission rod 4. The first rocker arm 2 has a predetermined operating length and is rotatably connected to the operating surface of the gate box 1, and can be rotated and adjusted accordingly. The second rocker arm 3 has a predetermined operating length, has a predetermined operating distance from the first rocker arm 2, and is rotatably connected to the operating surface of the gate box 1, and can be rotated and adjusted accordingly. The transmission rod 4 has a predetermined operating length and is rotatably connected to the first rocker arm 2 and the second rocker arm 3, and is used for mutual communication between the first rocker arm 2 and the second rocker arm 3.

[0026] The brake cam 6 structure includes two components: a bushing 5 and a cam 6. The bushing 5 is placed on the working surface of the gate box 1, has a predetermined working size, and can perform corresponding limiting and auxiliary operations. The cam 6 is placed on the working surface of the bushing 5 and is rotatably connected to the bushing 5, and can perform a rotation adjustment operation within a predetermined range around the connection with the bushing 5.

[0027] A corresponding groove hole is provided at the center of the bushing 5; the cam 6 is rotatably connected to the groove hole provided in the bushing 5 and can rotate around the groove hole provided in the bushing 5; and the cam 6 is eccentrically arranged.

[0028] The first rocker arm 2 and the second rocker arm 3 are rotatably connected to the working surface of the gate box 1 by bolts; the bushing 5 and the cam 6 are both multiple, and the working positions correspond to the working positions of the first rocker arm 2 and the second rocker arm 3.

[0029] The multi-rocker structure and the brake cam 6 structure are respectively placed on different wall surfaces of the gate box 1.

[0030] In the later operation process, the bushing 5 and the cam 6 provided in the present application cooperate with each other to prevent the brake pad from falling off and being misplaced, and to ensure that the brake strength and braking effect can be maintained in a complex use environment.

[0031] The brake assembly in the present application adopts a double-leading shoe drum brake design, and the braking effect is improved several times. The brake cam 6 adopts an integrated eccentric design to compensate for the inconsistent wear between the fixed point and the opening point when the shoe is opened, and at the same time plays a self-enhancing role in the braking force of the brake shoe.

[0032] The beneficial effects of this application:

[0033] 1. The braking effect is good and the braking force can be increased several times. During the braking process, the cam 6 rotates around the center of the groove hole set in the bushing 5, and the left and right shoes 7 can follow the friction force of the rotating brake hub to increase the momentum. The eccentrically designed cam 6 shaft can also play a force-increasing effect by virtue of the braking force, so the braking force is significantly better than the existing brakes.

[0034] 2. Long service life. Compared with the traditional φ160 assembly, the service life of the double-sided brake is extended by 1.5-2 times under the same working conditions.

[0035] 3. Anti-peeling: The friction material fixing plate, namely the cam 6 and the bushing 5, are provided with corresponding anti-stripping holes to prevent the brake pad from falling off and being misplaced.

[0036] 4. High braking reliability. The double-shoe brakes on the market are generally hydraulically driven, with complex manufacturing processes, high costs, slow response, and high failure rates. This application adopts a mechanical double rocker arm double cam 6 design, which has sensitive and reliable transmission.

[0037] 5. Self-compensation: the cam 6 shaft is designed according to the braking curve. After the cam 6 rotates and the shoe is worn, the shoe at the fixed end of the cam 6 can be stretched outward to automatically compensate for the shoe wear.

[0038] The brake shoe 7 of the present application is made of high-quality carbon steel by stamping, riveting, welding and pressing. The one-piece pressed ceramic brake pad has the advantages of good braking effect, good water resistance, good thermal recovery and water recovery. The ceramic fiber friction plate is pressed at high temperature on the brake shoe. While achieving the same braking effect, its wear rate is reduced by 45-50% compared with the original. Comprehensively judging, its service life is extended by about 30%.

[0039] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the present invention itself. Various changes may be made to it in form and detail without departing from the spirit and scope of the present invention as defined in the appended claims.
