Description

Technical Field

[0001] The utility model relates to the technical field of bicycle braking system accessories, and particularly relates to a disc braking device, an installation system, an oil pressure braking device and a bicycle. Background Art

[0002] In the prior art, some bicycle manufacturers generally equip 140-mm-diameter discs when leaving the factory due to cost considerations, especially for road bike disc brakes; while some bicycle enthusiasts or professional riders will convert the 140-mm-diameter disc into a 160-mm-diameter disc in order to meet the needs of long-time riding and strong braking.

[0003] The oil disc caliper is a braking device with strong braking ability, which is fixedly arranged at the front fork part of the bicycle. Specifically, two threaded holes are provided on the front fork, and the center distance between the two threaded holes is fixed. The brake pads of the oil disc caliper are arranged at the edge part of the disc, and the brake pads arranged on both sides of the disc are driven by oil pressure to clamp the disc, so as to achieve the purpose of braking.

[0004] Therefore, when the center distance of the installed oil disc caliper is fixed and the disc diameter is changed from 140 mm to 160 mm, the relative position between the brake pads and the disc edge changes. In order to achieve good braking effect, a 140 / 160 disc brake adapter is adopted in the prior art. One of the functions of the disc brake adapter is to increase the distance between the oil disc caliper and the surface of the front fork or rear fork, so that the oil disc caliper can correctly clamp the braking part of the disc. In addition, several holes are provided on the disc brake adapter, and two holes are also provided on the corresponding oil disc caliper. After selecting the corresponding holes on the disc brake adapter and corresponding them to the holes on the oil disc caliper, screws are used to fix the disc brake adapter and the oil disc caliper. Correspondingly, select the holes on the disc brake adapter that can match the center distance of the front fork holes, and install the disc brake adapter and the oil disc caliper on the front fork. That is to say, two installation operations are required to install the oil disc caliper on the front fork, and it is necessary to manually proofread the relationship between the holes on the disc brake adapter and the oil disc caliper, and the relationship between the holes on the disc brake adapter and the front fork. The operation steps are cumbersome, and setting multiple holes on the disc brake adapter and the oil disc caliper will weaken the structural strength of the disc brake adapter and the oil disc caliper, making the disc brake adapter and the oil disc caliper easy to be damaged.

Detailed Description of the Invention

[0034] The concept, specific structure and technical effects of the present utility model will be clearly and completely described below in conjunction with the embodiments and the accompanying drawings, so as to fully understand the purpose, features and effects of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, other embodiments obtained by those skilled in the art without creative efforts shall fall within the scope of protection of the present utility model. In addition, all the connection / connection relationships involved in the patent do not simply refer to the direct connection of components, but refer to the formation of a more optimal connection structure by adding or reducing connection accessories according to specific implementation situations. The various technical features in the creation of the present utility model can be interactively combined without conflicting with each other.

[0035] Referring to Figures 1 - 3 , a disc brake device includes an oil disc caliper 1 and a disc brake conversion seat part 2 integrally formed with the oil disc caliper.

[0036] By integrally setting the oil disc caliper 1 and the disc brake conversion seat part 2, compared with the prior art where the position of the oil disc caliper 1 and the disc brake conversion seat part 2 needs to be fixed first and then the disc brake conversion seat part 2 and the oil disc caliper 1 are fixed to the front fork, the present application only requires one installation operation (i.e., installing the disc brake device on the front fork), thus greatly simplifying the installation steps. This not only improves the installation efficiency but also reduces the error rate during installation; and the integrally formed design reduces the corresponding installation holes on the oil disc caliper 1 and the disc brake conversion seat part 2, enhancing the strength of the overall structure of the disc brake device, making the oil disc caliper and the disc brake conversion seat part more durable and not easily damaged;

[0037] In the prior art, after the oil disc caliper 1 is covered by two cover plates with screw holes, an oil cylinder is formed between the two cover plates, and then screws are passed through the two screw holes to lock the two cover plates. However, the setting of the screw holes will, on the one hand, cause stress concentration in this part, and the structure near the screw holes is prone to fracture; on the other hand, if the two cover plates are not tightly closed, the oil in the oil cylinder will flow out from the screw holes, and the reduction of the oil volume in the oil cylinder will lead to a decline in the braking effect;

[0038] Furthermore, the oil disc caliper 1 is of an integral structure, eliminating the need to set installation holes such as screw holes. While improving the structural strength, it can avoid the leakage of oil in the oil cylinder and extend the service life of the oil cylinder.

[0039] In one of the embodiments, referring to Figures 1 - 2 , further, the disc brake conversion seat part 2 is provided with a first through hole 21 and a second through hole 22 for installing the disc brake device. The first through hole 21 and the second through hole 22 are arranged on both sides of the oil disc caliper 1, which can improve the installation stability of the oil disc caliper 1;

[0040] Specifically, the oil disc caliper 1 includes a left oil cylinder 11 and a right oil cylinder 12 that are interconnected. The oil disc caliper 1 is also provided with an oil injection hole 131, and the oil injection hole 131 is connected to the left oil cylinder 11 and the right oil cylinder 12. A sealing oil plug 132 is detachably provided at the oil injection hole 131, which can simplify the maintenance and servicing steps of the oil disc caliper 1;

[0041] When the system needs to add or replace the brake oil, only the sealing oil plug 132 needs to be opened, and new brake oil can be injected through the oil injection hole 131.

[0042] In another embodiment, the disc brake conversion seat portion 2 is two tentacles integrally connected to the oil disc caliper 1.

[0043] Furthermore, the disc brake device is machined by a numerically controlled machine tool. Machining by a numerically controlled machine tool has the advantage of high manufacturing precision. For the disc brake device, high-precision machining can ensure that the clearance between the disc and the brake pads in the hydraulic caliper reaches the best state, thereby improving the sensitivity and stability of braking.

[0044] Specifically, the disc brake device is machined from aluminum profiles. Aluminum profiles have strong corrosion resistance. Generally, the disc brake device is an exposed accessory on the bicycle and needs to withstand exposure to the sun and rain washing. Aluminum profiles have good stability, which makes the disc brake device not easily affected by corrosion during long-term use and extends the service life of the disc brake device.

[0045] Furthermore, the oil disc caliper 1 further includes a left brake pad 141, a right brake pad 142, a left piston 151, and a right piston 152;

[0046] The left piston 151 and the right piston 152 are both circular in shape, which is conducive to forming a uniform oil pressure distribution between the left piston 151 / right piston 152 and the inner wall of the left oil cylinder / right oil cylinder, so as to ensure that the left piston 151 / right piston 152 can move smoothly and quickly when subjected to oil pressure;

[0047] Among them, the left brake pad 141 / right brake pad 142 is arranged on one side of the left piston 151 / right piston 152. The left piston 151 and the right piston 152 cooperate with the oil disc caliper housing to enclose the left oil cylinder / right oil cylinder; the movement of the left piston 151 / right piston 152 will push the left brake pad 14 / right brake pad 142 closer to or away from the disc to achieve braking or release;

[0048] The left brake pad 141 and the right brake pad 142 are both rectangular;

[0049] The center of the circle of the left piston 151 and the geometric center of the left brake pad 141 are on the same axis;

[0050] The center of the right piston 152 is on the same axis as the geometric center of the right brake pad 142; this alignment design ensures that the left piston 151 / right piston 152 can directly and accurately push the brake pads when moving, reducing unnecessary friction and energy loss, and maintaining the stability of the left brake pad 141 / right brake pad 142 during braking, preventing it from shifting or deforming due to uneven force.

[0051] A disc brake device installation system includes a front fork and the above-mentioned disc brake device. The front fork is provided with a first front fork mounting hole and a second front fork mounting hole. A first fixing member passes through the first through hole 21 in the first front fork mounting hole, and a second fixing member passes through the second through hole 22 in the second front fork mounting hole.

[0052] Specifically, the first through hole 21, the second through hole 22, the first front fork mounting hole, and the second front fork mounting hole can be threaded holes with internal threads, and the first fixing member and the second fixing member are provided with external threads.

[0053] An oil pressure brake device includes an oil pumping cylinder provided on the handlebar, a first pipeline connecting the oil pumping cylinder and the brake lever, and a second pipeline connecting the oil pumping cylinder and the above-mentioned disc brake device;

[0054] Among them, the oil pumping cylinder is a conventional component in the prior art, and it is provided with a third cylinder and a third piston provided in the third cylinder; the third cylinder, the second pipeline, and the oil circuit in the oil disc caliper 1 are sealed and communicate with each other;

[0055] Pulling the brake lever can drive the first pipeline to pull the third piston. The piston pumps the oil in the oil pumping cylinder along the second pipeline to the oil disc caliper 1. The oil pressure in the oil disc caliper 1 drives the left piston 151 and the right piston 152 to approach each other relatively, so that the left brake pad 141 / right brake pad 142 approaches the disc, realizing braking.

[0056] A bicycle is equipped with the above-mentioned disc brake device, the above-mentioned disc brake device installation system, or the above-mentioned oil pressure brake device.

[0057] The above is a specific description of the preferred embodiments of the present invention, but the present invention is not limited to the above embodiments. Those skilled in the art can make various equivalent deformations or substitutions without departing from the spirit of the present invention, and these equivalent deformations or substitutions are all included in the scope defined by the claims of this application.
