Abstract

The utility model relates to the field of electro-tricycle braking mechanisms, in particular to a structure of a front brake with double gear shafts, which comprises a rocker arm, a double gear shaft structure and a brake shoe. One end of the double-rotating-gear-shaft structure is connected with the double-rotating-gear-shaft structure through a bolt, and the other end of the double-rotating-gear-shaft structure is connected with the brake shoe through a tension spring. At present, a front brake of an electric tricycle is of a single-gear shaft type, the contact area is small in the braking process, and the braking effect is poor.

Meanwhile, the double-rotating-gear-shaft structure is of a hidden structure, the appearance is simple, and the double-rotating-gear-shaft structure can be universally used with other parts.

Description

Technical Field

[0001] The utility model relates to the field of brake mechanisms for electric tricycles, in particular to a structure of a double-shift axle front brake. Background Art

[0002] A brake is a device that decelerates, stops, or maintains a moving part (or moving machinery). It is a mechanical component that stops or decelerates moving parts in machinery. Commonly known as brakes or gates, brakes primarily consist of a frame, brake components, and an operating mechanism. Some brakes also feature automatic adjustment for brake component clearance. To reduce braking torque and overall size, brakes are typically installed on high-speed shafts. However, for larger equipment with higher safety requirements (such as mine hoists and elevators), they should be installed on low-speed shafts closer to the working parts.

[0003] At present, the front brake of electric tricycles is of single-rotation gear shaft type, which has a small contact area during braking and poor braking effect. Utility Model Content

[0004] The purpose of the utility model is to provide a structure of a double-shift shaft front brake to solve the above-mentioned problems existing in the prior art.

[0005] Technical solution: A structure of a dual-shift shaft front brake, including a rocker arm, a dual-shift shaft structure and a brake shoe; one end of the dual-shift shaft structure is connected to the dual-shift shaft structure by a bolt, and the other end is connected to the brake shoe by a tension spring.

[0006] In a further embodiment, the dual shift gear structure includes a first shift gear shaft and a second shift gear shaft, and the first shift gear shaft and the second shift gear shaft are connected to each other via a pull rod.

[0007] In a further embodiment, a housing is provided between the rocker arm and the dual-shift shaft structure, and the dual-shift shaft structure passes through the housing and is connected to the rocker arm via the bolts.

[0008] In a further embodiment, there are multiple brake shoes, which are respectively connected to the shift shaft one and the shift shaft two; there are multiple tension springs, which are all placed between the multiple brake shoes and the shift shaft one and the shift shaft two.

[0009] Beneficial effects: The utility model relates to a structure of a double-rotating shaft front brake, which relates to the field of electric tricycle braking mechanisms, including a rocker arm, a double-rotating shaft structure and a brake shoe; one end of the double-rotating shaft structure is connected to the double-rotating shaft structure by a bolt, and the other end is connected to the brake shoe by a tension spring. At present, the front brake of an electric tricycle is a single-rotating shaft type, which has a small contact area during braking and a poor braking effect. The utility model changes it to a double single-rotating shaft to increase the contact surface between the brake shoe and the interchangeable drum, thereby increasing the braking effect. At the same time, the double-rotating shaft type is a hidden structure with a simple appearance and can be used interchangeably with other parts. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features known in the art are not described to avoid confusion with the present invention.

[0014] Example 1:

[0015] The structure of the dual-shift shaft front brake proposed in this embodiment includes a rocker arm 1, a dual-shift shaft structure and a brake shoe 8; one end of the dual-shift shaft structure is connected to the dual-shift shaft structure by a bolt 2, and the other end is connected to the brake shoe 8 by a tension spring 7. The dual-shift structure includes a shift shaft 1 4 and a shift shaft 2 6, and the shift shaft 1 4 and the shift shaft 2 6 are connected to each other by a pull rod 5. A housing 3 is provided between the rocker arm 1 and the dual-shift shaft structure, and the dual-shift shaft structure passes through the housing 3 and is connected to the rocker arm 1 by the bolt 2. There are multiple brake shoes 8, which are respectively connected to the shift shaft 1 4 and the shift shaft 2 6. There are multiple tension springs 7, which are all placed between the multiple brake shoes 8 and the shift shaft 1 4 and the shift shaft 2 6. In a further preferred embodiment, the rocker arm 1 is connected to the front brake line.

[0016] Example 2:

[0017] Based on the first embodiment, the rocker arm 1 is fixed to the shift shaft 1 4 by a bolt 2, the pull rod 5 connects the shift shaft 1 4 and the shift shaft 2 6, and the brake shoe 8 is connected to the shift shaft, and the tension spring 7 is fixed between the two brake shoes 8 to provide a return effect.

[0018] Based on the above embodiment, the working process of the utility model is as follows: the front brake line 10 pulls the rocker arm 1, and the rocker arm 1 rotates the shift shaft 4. When the shift shaft 4 is pulled, the pull rod 5 moves, driving the shift shaft 2 6, thereby expanding the brake shoe 8 to increase the contact area and enhance the braking effect.

[0019] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be interpreted 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.
