Description

Technical Field

[0002] A brake is a mechanical part that stops or decelerates moving parts in a machine. In a vehicle, a brake is also called a braking device, which is a device with functions such as decelerating, stopping, or maintaining a stopped state of the vehicle. In an existing drum brake, during braking, the friction lining and the brake drum come into contact with each other, and rely on sliding friction to achieve the braking effect.

[0003] During the braking process, the temperature of the friction lining and the brake drum is relatively high, which causes the friction lining to become soft, the friction coefficient to decrease, affecting the braking effect. Moreover, too high a temperature of the brake drum will lead to a lower service life, also affecting the braking effect, and there are certain potential safety hazards. Therefore, it is necessary to propose a full - circumference surrounding type braking device that can reduce the temperature of the braking device. Content of the Utility Model

[0027] In order to solve the problem, the embodiment of the utility model provides a full-circle encircling brake device. The technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figures 1-3 , This embodiment provides a full-circumferential embracing brake device, characterized in that it includes a base 101, which is arranged on the axle;

[0029] The brake drum 201 is arranged at the edge of the base 101; the brake pad 301 is arranged at the edge of the upper surface of the base 101, and can contact with the brake drum 201 after rotation, and achieve the braking function through the friction generated by the contact;

[0030] The brake wheel cylinder 401 is arranged on the upper surface of the base 101, and the telescopic end of the brake wheel cylinder 401 is correspondingly connected to the brake pad 301 to complete the action of pushing the brake pad 301 and assisting the brake pad 301 to complete the braking function;

[0031] A return spring 501 is provided on the brake pad 301 to pull back the brake pad 301 to cancel the braking function;

[0032] The cooling device 600 is disposed on the base 101 to allow outside air to enter the brake drum 201 to reduce the internal temperature of the brake drum 201 .

[0033] Furthermore, the cooling device 600 includes a plurality of holes which are arranged through the base 101; the plurality of holes are provided with openings facing the direction of the wheels below the base 101 to accelerate the entry of outside air into the brake device, so as to quickly reduce the internal temperature of the brake device.

[0034] Furthermore, the fixed end of the wheel brake cylinder 401 is provided with a support 402 ; one end of the support 402 is connected to the fixed end of the wheel brake cylinder 401 , and the other end is connected to the brake pad 301 to complete the action of fixing the wheel brake cylinder 401 .

[0035] Furthermore, the brake pad 301 is provided with a limit screw 302 at the connection end with the support 402, so that the brake pad 301 is fixed and can rotate around the limit screw 302 to complete the braking and canceling of the brake pad 301.

[0036] Further, there are four brake pads 301, which are arranged in a circumferential array at the edge of the base 101; there are four brake wheel cylinders 401, which are arranged in a circumferential array on the upper surface of the base 101; there are four return springs 501, which are arranged in a circumferential array at the central holes of the brake pads 301 to improve the braking effect.

[0037] Further, the brake drum 101 is circular in shape to achieve better contact with the brake pads 301.

[0038] During use: Start the braking device. The telescopic end of the brake wheel cylinder 401 pushes the brake pad 301, causing the brake pad 301 to rotate around the limit screw 302 and finally contact the brake drum 201. The return spring 501 is stretched under force. Due to the pressure of the brake wheel cylinder 401 on the brake pad 301, a sliding friction force is generated between the brake pad 301 and the brake drum 201 to achieve the braking effect.

[0039] Turn off the braking device. The telescopic end of the brake wheel cylinder 401 retracts, and the return spring 501 rebounds and contracts, driving the brake pad 301 back to its original position and becoming relatively stationary with the brake wheel cylinder 401 again.

[0040] When one of the four brake pads 301 is damaged and the other three brake pads 301 are working properly, start the braking device. The telescopic end of the brake wheel cylinder 401 pushes the brake pad 301, and the contact between the brake pad 301 and the brake drum 201 proceeds normally, and the braking function is completed normally.
