Abstract

A cam-driven brake module is connected to a hydraulic brake system and includes a brake lever, a drive wheel system, and a cam structure. The brake lever has a drive feature structure at its end. The drive wheel system includes a drive wheel and a driven wheel, which are in contact with the drive wheel, the driven wheel, and the drive feature structure. The cam structure rotates coaxially with the driven wheel. When the user actuates the brake lever, the drive feature structure drives the drive wheel system to change its position by a deflection angle, and the cam structure sequentially pushes the drive piston rod of the hydraulic brake system according to its feature profile, thereby generating braking force through the transmission of the hydraulic brake system.

Claims

1. A cam-driven brake module connected to a hydraulic brake system, comprising: a brake lever with a drive feature structure at its end; a transmission wheel system including a drive wheel and a driven wheel, the drive wheel contacting and engaging with the driven wheel and the drive feature structure; and a cam structure coaxially rotating with the driven wheel, the cam structure having a feature profile; wherein when a user operates the brake lever, the drive feature structure of the brake lever drives the transmission wheel system to change a position deflection angle, and the cam structure, according to the position deflection angle, drives the feature profile to sequentially push against the transmission piston rod of the hydraulic brake system, thereby generating braking force through the transmission of the hydraulic brake system.

2. The cam-driven brake module as described in claim 1, wherein the drive wheel is larger than the driven wheel to amplify the position deflection angle.

3. The cam-driven brake module as described in claim 1, wherein the feature profile is designed in reverse based on the brake curve.

4. The cam-driven brake module as described in claim 1, wherein the feature profile is composed of a multi-segment interval curve design.

5. The cam-driven brake module as described in claim 4, wherein the multi-segment interval curve adopts a locally discrete linearization design.

6. The cam-driven brake module as described in claim 1, wherein the transmission wheel system is a single-stage design or a cascade design.

7. The cam-driven brake module as described in claim 1, wherein the drive feature structure is a toothed structure.
