Description

Technical Field

[0001] The present application relates to the technical field of brakes, and in particular to a centrifugal brake. Background Art

[0002] Brakes usually refer to an important component in the braking system of a vehicle, also known as a brake device. The function of the brake is to slow down or stop the wheels through braking torque to ensure that the vehicle can stop or slow down safely during driving. In some small mechanical equipment, such as lawn mowers, generators, etc., centrifugal brakes can be used to achieve braking according to the speed of the equipment. When the equipment is running, the centrifugal force will make the brakes take effect, thereby slowing down or stopping the rotation of the equipment.

[0003] With respect to the above-mentioned related technologies, the inventor believes that in the prior art, some brakes will generate friction heat when working, and poor lubrication will easily lead to excessive heat accumulation. Overheating will easily cause damage to the brake components, such as increased wear of brake pads and brake discs, shortening the life of the brake system. Insufficient lubrication will easily lead to a decline in brake performance, making it difficult to provide sufficient braking force or causing unstable braking effect, thereby having a negative impact on the safety of the vehicle or equipment. Difficult lubrication will also easily lead to increased friction between brake components, thereby causing noise problems. Therefore, in response to the above deficiencies, a centrifugal brake is proposed. Summary of the invention

[0029] The following is combined with Figure 1 -Attached Figure 3 , further details of this application are given.

[0030] A centrifugal brake, referring to Figure 1-3, including a shell 1, which is the external protection structure of the brake, used to fix and protect the internal components. The shell 1 is usually made of a strong material to withstand the force and pressure in the braking operation. A metal plate 2 is fixedly connected to the top of the shell 1. A brake pad 3 is installed on the friction material on the top of the metal plate 2. The brake pad 3 is used to contact with other components and produce a braking effect. A connecting seat 4 is fixedly connected to the structure on the top of the brake pad 3. The connecting seat 4 is used to connect other brake system components. A movable plate 5 is located on both sides of the connecting seat 4. The movable plate 5 can slide. The movable plate 5 participates in the braking operation and affects the braking effect. The counterweight block 6 located on the top of the movable plate 5 is used to balance and adjust the movement and stability of the brake. The protrusions 7 fixedly connected to the front and rear sides of the counterweight block 6 interact with other components to affect the movement of the brake. The spring 8 installed on the outside of the two protrusions 7 provides elastic support so that the brake can respond and release quickly. The rotating shaft 9 located in the shell 1 is connected to other components of the brake to support and allow the rotational movement of the brake.

[0031] Reference Figure 1 , Figure 3 The support seat 10 is connected to the support structure outside the rotating shaft 9 to provide additional support and stability during the movement of the brake. The slide grooves 11 opened inside the left and right sides of the support seat 10 are used to guide and control the movement of the support seat 10. The lubrication component is a component used to keep the friction between the internal components of the brake small and the movement smooth. The lubrication component includes a square column 12, an inner cavity 13 located inside the square column 12, which is used to provide movement of the sliding block 15, and a spring 14 installed in the inner cavity 13, which is used to provide appropriate pressure during lubrication. The sliding block 15 is installed in a block structure on the inner wall of the inner cavity 13 for sliding movement and achieving lubrication effect together with other components. The oil outlet 16 is an opening located inside the sliding block 15 for the outflow of the lubricating medium. The oil storage tank 17 is a groove located inside the square column 12 for storing the lubricating medium. The connecting ports 18 located on both sides of the oil storage tank 17 may be used for the supply and discharge of the lubricating medium. The bolts 19 installed on the outside of the metal plate 2 are used to connect and fix the metal plate 2.

[0032] The implementation principle of the embodiment of the present application is as follows: when the motor drives the rotating shaft 9 to rotate, under the centrifugal force of the rotating shaft 9, the rotating shaft 9 drives the metal plate 2 to rotate, so that the metal plate 2 drives the brake pad 3 to rotate, thereby realizing that the brake pad 3 drives the rotation of the connecting seat 4, and the movement of the movable plate 5 is driven by the movable plate 5, so that the movable plate 5 drives the rotation of the counterweight block 6, and the counterweight block 6 drives the movement of the protrusion 7, and the protrusion 7 drives the extension of the spring 8, and after the brake pad 3 contacts the metal plate 2, the brake is more stable. By rotating the rotating shaft 9, the rotating shaft 9 drives the square column 12 to move. After the sliding block 15 is engaged with the through hole on the rotating shaft 9, the spring 14 drives the sliding block 15 to move, so that the lubricating oil in the oil storage tank 17 enters the sliding block 15 through the connecting port 18, and the lubricating oil in the oil outlet 16 drips out through the oil outlet 16, thereby achieving quantitative lubrication of the brake, thereby preventing the brake components from being damaged, increasing the service life of the brake system, improving the safety of the vehicle or equipment, and reducing the noise problem.

The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
