Description

Technical Field

[0001] This utility model relates to the field of mountain bike brake components, and more specifically to a press-fitted disc brake. Background Technology

[0002] A brake disc is a component of the braking system used in mountain bikes. Its braking principle involves mounting the brake disc to the wheel hub, allowing it to rotate with the wheel. Brake pads are positioned on opposite sides of the brake disc. To reduce speed or stop the bike, the brake disc is clamped, and friction between the two achieves the desired reduction or stop. For example, Chinese utility model CN201220028437.2 discloses an improved fixing structure for bicycle brake discs, where the brake disc and connecting seat are connected by bolts. This assembly process is cumbersome, and after prolonged use, the disc is prone to loosening due to the bike's vibrations. Furthermore, existing mountain bike technology prioritizes lightweight design for higher speeds; the brake disc in the aforementioned patent could be further improved to further reduce its weight. Summary of the Invention

[0003] In view of this, the present invention provides a press-fit type locking disc.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a press-fit type locking disc, comprising:

[0005] The disc is circular in shape and has a hollowed-out groove. The outer circumference of the disc is wavy.

[0006] The connecting ring is riveted to the center of the disc, and the inner ring of the connecting ring is provided with teeth;

[0007] The disc of this technology features a hollowed-out groove, which reduces the weight of the disc and makes it suitable for mountain bikes. This helps reduce the weight of the mountain bike and also facilitates heat dissipation. In addition, the connecting ring is installed on the disc by riveting, which simplifies the installation and production process.

[0008] As a preferred embodiment of this utility model, the disc includes: an inner ring, an outer ring, and multiple connecting strips connecting the inner ring and the outer ring;

[0009] Multiple hollow areas are formed between the inner ring, outer ring, and connecting strip;

[0010] The hollowed-out area in this technology also helps to reduce the weight of the disc, thereby reducing the weight of the mountain bike.

[0011] In a preferred embodiment of this utility model, the connecting strip extends along the tangent direction of the inner ring.

[0012] As a preferred embodiment of this utility model, the outer ring is provided with multiple hollow grooves, which are arranged in two sets in a ring.

[0013] In a preferred embodiment of this utility model, both the outer circumference and the inner circumference of the outer ring are arranged in a wavy pattern.

[0014] In a preferred embodiment of this utility model, the connecting ring is riveted to the inner ring; the bottom surface of the connecting ring has rivet feet; after the inner ring and the connecting ring are assembled, a hollow space is left in the center of the locking disc to facilitate installation and locking, and also to leave space for the installation of other auxiliary accessories.

[0015] As a preferred embodiment of this utility model, the diameter of the connecting ring gradually decreases from the bottom to the top surface, forming an arc-shaped transition side; this technology not only makes the product have a smooth shape, but also reduces wind resistance.

[0016] The other beneficial technical effects of this utility model are specifically manifested as follows:

[0017] 1. Braking: When braking, the brake pads in the brake caliper clamp the disc, and the friction between the two converts the kinetic energy of the mountain bike into heat energy, which slows down the wheel speed until it stops, allowing the rider to effectively control the speed and stop in time.

[0018] 2. Fast heat dissipation: The disc is exposed to the air and has a large heat dissipation area. Under conditions of continuous braking or long downhill driving, which require frequent braking, it can quickly dissipate the heat generated by braking and avoid the decline in braking performance due to heat accumulation.

[0019] 3. Provides stable braking force: Compared with traditional braking systems, disc brakes are less affected by environmental factors such as road bumps and mud, and can provide riders with stable and reliable braking force in complex mountain riding conditions;

[0020] 4. Precise control: The disc brakes, combined with the high-performance braking system, allow riders to precisely control the braking force, achieving smooth and gradual braking, and improving riding comfort and control. Attached Figure Description

[0027] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0028] A type of press-fit disc locking mechanism, please refer to [link / reference]. Figure 1-3 As shown, it includes: a disc 100 and a connecting ring 200.

[0029] The disc 100 is arranged in a circular shape, and the disc 100 is provided with a hollow groove 110. The outer circumference 120 of the disc 100 is arranged in a wave shape.

[0030] The connecting ring 200 is riveted to the center of the disc 100, and the inner ring of the connecting ring 200 is provided with teeth 210.

[0031] In this technology, the disc 100 can be made of new materials, which can effectively reduce the weight without compromising its original performance. The hollowed-out groove 110 throughout can also effectively reduce the weight of the disc 100. Compared with traditional braking systems, when this disc is used in mountain bikes, the disc brake is less affected by environmental factors such as road bumps and mud, and can provide stable and reliable braking force for riders in complex mountain riding conditions.

[0032] The connecting ring 200 and the disc 100 are connected by riveting, which facilitates the installation and production process. At the same time, the riveting connection is more stable than the screw connection in the prior art, and also prevents loosening during bumps.

[0033] Furthermore, the disc 100 includes: an inner ring 102, an outer ring 101, and multiple connecting strips 103 connecting the inner ring 102 and the outer ring 101; the inner ring 102, the outer ring 101, and the connecting strips 103 form multiple hollow areas 130.

[0034] Specifically, the inner ring 102, the outer ring 101, and the connecting strip 103 are made as a single unit, and the hollow area 130 is also to reduce the weight of the disc 100.

[0035] Furthermore, the connecting strip 103 extends along the tangential direction of the inner ring 102; as... Figure 2 As shown, there are six connecting strips 103, each with a 60° chamfer, and the six connecting strips 103 are arranged symmetrically at the center.

[0036] Furthermore, the outer ring 101 is provided with a plurality of hollowed-out grooves 110, which are arranged in two sets in a ring, further reducing the weight of the disc 100.

[0037] Furthermore, both the outer circumference 120 and the inner circumference 140 of the outer ring 101 are arranged in a wavy shape.

[0038] Furthermore, the connecting ring 200 is riveted to the inner ring 102; the bottom surface 201 of the connecting ring 200 has a riveting foot 220, which is formed on the bottom of the connecting ring 200, effectively reducing assembly steps and improving assembly efficiency.

[0039] like Figure 2 As shown, after the connecting ring 200 is assembled into the inner ring 102, a hollow space is left in the center of the locking disc to facilitate installation and locking, and also to leave space for the installation of other accessories.

[0040] Furthermore, the diameter of the connecting ring 200 gradually decreases from the bottom surface 201 to the top surface, and forms an arc-shaped transition side surface 202, which makes the product aesthetically pleasing and reduces wind resistance.

[0041] This technology's press-fit disc brakes can be used in mountain bikes and regular bicycles.

[0042] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
