Description

Technical Field

[0001] The utility model relates to the technical field of bicycle brakes, in particular to a hydraulic brake device for bicycles. Background Technique

[0002] At present, different types of brake devices are equipped on bicycles, and hydraulic brakes are one of them. When the brake handle is squeezed, the handle pushes the hydraulic oil, and the hydraulic oil flows through the oil pipe to the brake caliper, pushing the piston in the caliper, so that the brake pads contact the wheel to generate frictional force and achieve braking.

[0003] However, when riding a bicycle on a mountain road, the brakes need to be used frequently, which is often a great test for the safety of the brakes. At present, most of the bicycles on the market are equipped with a brake disc for each wheel, which may lead to a reduction in safety. At the same time, a large amount of noise will be generated when the brake pads rub against the brake disc, thus affecting the comfort of the rider. For this reason, we propose a hydraulic brake device for bicycles. Content of the Utility Model

[0004] The purpose of the utility model is to provide a hydraulic brake device for bicycles to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A hydraulic brake device for bicycles, including a wheel and a bracket. A rotating rod is fixedly connected to the middle of the wheel. One end of the rod wall of the rotating rod is fixedly connected with a first brake disc, and a second brake disc is fixedly connected to the rod wall of the rotating rod close to the first brake disc;

[0006] Both ends of the bracket are penetrated and embedded with two hydraulic components. The output ends of the two hydraulic components are both fixedly connected with brake pads. A number of reinforcing strips arranged in a conical shape are fixedly connected to the outer surfaces of the brake pads. A rubber noise reduction ring is sleeved on the outer surfaces of the brake pads. Plug rods are fixedly connected to the inner walls of the upper and lower ends of the rubber noise reduction ring. A number of reinforcing grooves arranged in a conical shape are opened on the inner surfaces of the rubber noise reduction ring.

[0007] Preferably, a number of first heat dissipation holes and second heat dissipation holes are penetrated and opened on the surfaces of the first brake disc and the second brake disc, and both ends of the brake pads correspond to the two side edges of the first brake disc and the second brake disc.

[0008] Preferably, a number of grooves are opened on the surfaces of the brake pads.

[0009] Preferably, slots are opened on the upper and lower end surfaces of the brake pads, and the inner diameter of the slots is adapted to the outer diameter of the plug rods.

[0010] Preferably, the inner diameters of a number of the reinforcing grooves are adapted to the outer diameters of a number of the reinforcing strips.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows: When braking the first brake disc and the second brake disc through the brake pads arranged at both ends, the braking effect on the two brake discs can be improved. Then, through the arranged rubber noise reduction ring, inserting rod, slot, reinforcing strip, and reinforcing groove, the noise during braking can be reduced. When the brake pads are rubbing, a large amount of heat will be generated, causing the reinforcing strip to expand the reinforcing groove, so that the rubber noise reduction ring is more firmly sleeved on the brake pads.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figures 1-4 , the present utility model provides a technical solution: A bicycle hydraulic braking device includes a wheel 1 and a bracket 2. A rotating rod 11 is fixedly connected to the middle of the wheel 1. One end of the rod wall of the rotating rod 11 is fixedly connected with a first brake disc 12, and the rod wall of the rotating rod 11 is fixedly connected with a second brake disc 13 on one side close to the first brake disc 12;

[0019] Both ends of the bracket 2 are penetrated and provided with two hydraulic components 21. Output ends of the two hydraulic components 21 are fixedly connected with brake pads 22. Outer surfaces of the brake pads 22 are fixedly connected with a plurality of reinforcing strips 24 arranged in a conical shape. Rubber noise reduction rings 3 are sleeved on outer surfaces of the brake pads 22. Inner walls of upper and lower ends of the rubber noise reduction rings 3 are fixedly connected with insertion rods 31. Inner surfaces of the rubber noise reduction rings 3 are provided with a plurality of reinforcing grooves 32 arranged in a conical shape.

[0020] Furthermore, a plurality of first heat dissipation holes 102 and second heat dissipation holes 103 are penetrated and provided on surfaces of the first brake disc 12 and the second brake disc 13. And both ends of the brake pads 22 correspond to two side edges of the first brake disc 12 and the second brake disc 13. Heat dissipation effects of the first brake disc 12 and the second brake disc 13 can be improved through the first heat dissipation holes 102 and the second heat dissipation holes 103.

[0021] Furthermore, a plurality of grooves 25 are provided on surfaces of the brake pads 22. The plurality of grooves 25 can increase frictional force of the brake pads 22.

[0022] Furthermore, insertion slots 23 are provided on upper and lower surfaces of the brake pads 22. And inner diameters of the insertion slots 23 are adapted to outer diameters of the insertion rods 31. The insertion rods 31 are clamped into the insertion slots 23, so that the rubber noise reduction rings 3 are sleeved on outer ends of the brake pads 22.

[0023] Furthermore, inner diameters of the plurality of reinforcing grooves 32 are adapted to outer diameters of the plurality of reinforcing strips 24. When the brake pads 22 are in contact friction with the brake disc, a large amount of heat will be generated by the brake pads 22 to cause expansion. The reinforcing strips 24 will continuously expand outwards against the reinforcing grooves 32, so that the rubber noise reduction rings 3 are sleeved on the brake pads 22 more stably.

[0024] Specifically, when using the present utility model, when a bicycle brakes, the hydraulic components 21 will drive the brake pads 22. The two brake pads 22 will respectively be in contact friction with the first brake disc 12 and the second brake disc 13. The two brake discs can improve the braking effect. When the brake pads 22 are in contact friction with the brake disc, a large amount of heat will be generated by the brake pads 22 to cause expansion. The reinforcing strips 24 will continuously expand outwards against the reinforcing grooves 32, so that the rubber noise reduction rings 3 are sleeved on the brake pads 22 more stably. Thereby, a certain amount of noise can be reduced during the braking process, and thus the comfort of the rider is improved.

[0025] Although embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
