Description

Technical Field

[0001] This utility model relates to the field of brake technology, specifically a single-shoulder front shock absorber compatible with both disc brake and drum brake systems. Background Technology

[0002] Traditional front shock absorbers for motorcycles, electric bikes, and other two- and three-wheeled vehicles often only support a single type of braking system: either disc brakes or drum brakes. This structure necessitates the production, sales, and maintenance of various shock absorber models to meet diverse customer needs, increasing inventory costs and management complexity. Furthermore, for users, replacing the braking system often requires replacing the entire shock absorber assembly, which is neither convenient nor economical. The limited brake interface of existing front shock absorbers forces manufacturers to produce separate shock absorbers compatible with either disc or drum brakes, resulting in complex material management and high production line switchover costs. Finally, users retrofitting their braking systems later on require replacing the entire shock absorber, making it uneconomical.

[0003] To address this, a single-shoulder front shock absorber compatible with both disc brake and drum brake systems is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a single-shoulder front shock absorber that is compatible with both disc brake and drum brake systems, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A single-shoulder front shock absorber compatible with disc brake and drum brake systems includes a steering column, a large nut, a fork, a disc brake aluminum canister, a drum brake aluminum canister, a lower connecting plate, a disc brake caliper, a disc brake disc, a front wheel axle, and a brake drum, wherein the steering column and the lower connecting plate are interference-fitted.

[0007] The fork is connected to the disc brake aluminum barrel and the drum brake aluminum barrel respectively;

[0008] The disc brake aluminum barrel and drum brake aluminum barrel are installed on the lower connecting plate;

[0009] The front wheel axle passes sequentially through the disc brake aluminum barrel, disc brake disc, wheel, and drum brake aluminum barrel;

[0010] The disc brake caliper is mounted on the disc brake disc.

[0011] Furthermore, the fork is composed of a right fork and a left fork.

[0012] Furthermore, the right fork is installed on the disc brake aluminum barrel, the left fork is installed on the drum brake aluminum barrel, and the disc brake aluminum barrel and the drum brake aluminum barrel are respectively installed in the round holes on both sides of the lower connecting plate.

[0013] Furthermore, the front wheel axle passes sequentially through the disc brake aluminum barrel, disc brake disc, wheel, and drum brake aluminum barrel before being secured by a nut.

[0014] Furthermore, the front wheel axle passes sequentially through the disc brake aluminum barrel, the wheel, the brake drum, and the drum brake aluminum barrel before being secured by a nut.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] Innovative Structural Design: While maintaining the basic structure of a traditional single-shoulder front shock absorber, this ingenious design allows it to function as both a hydraulic disc brake and a mechanical drum brake. This is achieved through the addition of a detachable brake interface module, allowing users or maintenance personnel to easily replace the appropriate brake components as needed.

[0017] High versatility: The shock absorber of this utility model adopts a standardized design, ensuring compatibility with the wheel hubs, frames and other components of most two-wheeled vehicles on the market. It can be installed and used without major modifications to the vehicle, which greatly improves the versatility and market adaptability of the product.

[0018] Easy switching: With simple tool operation, users can quickly switch from disc brakes to drum brakes or vice versa without replacing the entire shock absorber, which saves costs and improves installation efficiency.

[0019] Enhanced safety and comfort: Whether using disc brakes or drum brakes, this invention ensures good braking performance and riding stability. At the same time, the single-shoulder front shock absorber design helps absorb road vibrations and improve riding comfort. Attached Figure Description

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Example 1:

[0025] Please see Figure 1-2 This utility model provides a technical solution:

[0026] A single-shoulder front shock absorber compatible with disc brake and drum brake systems includes a steering column 1, a large nut 2, a fork, a disc brake aluminum barrel 4, a drum brake aluminum barrel 6, a lower connecting plate 7, a disc brake caliper 8, a disc brake disc 9, a front wheel axle 10, and a brake drum 11.

[0027] The front shock absorber assembly sequence is as follows: first, the steering column 1 is interference-fitted onto the lower connecting plate 7; then, the right fork 3 is assembled with the disc brake aluminum barrel 4, and the left fork 5 is assembled with the drum brake aluminum barrel 6. Then, these two parts are respectively installed into the left and right round holes on the lower connecting plate 7 and tightened securely with the large nut 2. The front shock absorber assembly is complete.

[0028] The disc brake assembly method involves first passing the front wheel axle 10 through the disc brake aluminum barrel 4, disc brake disc 9, wheel 12, and drum brake aluminum barrel 6 in sequence, then securing it firmly with a nut, and finally installing the disc brake caliper 8 onto the disc brake disc 9 to achieve the disc brake function.
