TECHNICAL FIELD

[0001] The utility model relates to the technical field of bicycle accessory improvement, specifically relates to a bicycle disc brake foot support and speed changer combination connecting mechanism. BACKGROUND

[0002] In the development history of bicycles, disc brakes, foot supports and speed changers as key components, their installation methods and layouts have a decisive influence on the overall performance of bicycles and user experience. In traditional bicycle design, the installation position of the speed changer is very special, which makes it difficult to install the foot support in the same area. The speed changer needs stable support and accurate positioning to ensure the smoothness and stability of the speed change operation during cycling, which results in the occupation of the surrounding space and the inability to provide a suitable installation site for the foot support. If the foot support is forcibly installed nearby, it will damage the overall structural balance of the bicycle and affect the normal operation of the speed changer.

[0003] At the same time, there are many problems in the installation of disc brakes. The traditional disc brake support seat and mounting hole design lack pertinence. When braking, the disc brake is prone to vibration and displacement, which not only reduces the braking effect, but also poses a threat to cycling safety. Moreover, the connection method between components is complex, and when a component needs to be repaired or replaced, a large number of other parts often need to be disassembled, which not only consumes a lot of time and labor cost, but also may cause damage to other components due to frequent disassembly.

[0020] Installation process

[0021] Preparation: carefully check the first connecting piece 1 and the second connecting piece 2 to ensure that there is no damage such as scratch and deformation at each connecting part, and there is no impurities such as dust and debris. Measure the size of each component to confirm that it is consistent with the design drawing. Prepare installation tools such as wrench, screwdriver, torque wrench, and matching M8 bolts, nuts and positioning pins.

[0022] Foot support installation: Place the first connecting piece 1 on the workbench, insert one end of the foot support 4 into the first foot support connecting hole 102, then align the second connecting piece 2, and smoothly insert the other end of the foot support 4 into the second foot support connecting hole 202. Use a wrench to pass a matching M8 bolt through the two connecting holes, then tighten the nut according to the specified torque 20N·m, and fasten it to ensure that the foot support 4 is stable and there is no obvious displacement when shaken gently.

[0023] Disc brake installation: Hold the disc brake 5 and align its installation position with the first disc brake mounting hole 103 on the first connecting piece 1. Use a screwdriver to screw in the screw for preliminary fixation, with moderate force to ensure that the disc brake 5 does not fall off. Then place the second connecting piece 2 close to the disc brake 5, with the second disc brake support seat 201 fitting the other side of the disc brake 5. Use a screwdriver to tighten the screw to further fix the disc brake 5. After installation, manually rotate the wheel to check if the gap between the disc brake 5 and the disc is uniform, ensuring that there is no jamming phenomenon when braking.

[0024] Gear installation: Align the mounting hole of the gear 3 with the first gear mounting hole 104 on the first connecting piece 1, and insert the positioning pin for preliminary positioning. Align the second gear mounting hole 204 on the second connecting piece 2 with the mounting hole on the other side of the gear 3, and insert the positioning pin. Use a torque wrench to pass a high-strength M10 bolt through the gear mounting holes of the two connecting pieces and the mounting hole of the gear 3 in sequence, and tighten the bolt according to the specified torque 30N·m. After installation, operate the gear handle to check if the gear 3 shifts smoothly and the chain switches between different gears normally.

[0025] Installation effect

[0026] After the above installation steps, the gear 3, foot support 4, and disc brake 5 are successfully installed on the mountain bike through the first connecting piece 1 and the second connecting piece 2. In subsequent riding tests, the foot support 4 stably supports the bike, the disc brake 5 brakes sensitively, the gear 3 shifts smoothly, and the entire combined connecting mechanism operates well, achieving the expected design purpose.
