Description

Technical Field

[0001] This utility model relates to a brake arm force and preload adjustment device, and more particularly to a brake arm force and preload adjustment device that can be installed between the brake arm and the brake master cylinder, so as to quickly and conveniently adjust the stiffness of the brake arm, and adjust the free stroke caused by the loose structure of the original brake master cylinder, thereby improving the braking sensitivity. Background Technology

[0002] In traditional vehicles, the right foot brake controls the rear wheel. There are two good braking methods: engine braking and rear wheel braking. The traditional braking structure design involves the foot pedal pressing the brake lever, which then feeds back to the tension spring. This affects the sensitivity of the foot pedal. However, traditional technology cannot improve this problem, as the tension spring cannot be adjusted independently, which can lead to the tension spring being either too soft or too hard.

[0003] In addition, all original factory motorcycles have a free travel, which means that the brake does not engage after the user presses it. This is caused by the accumulated tolerances in the assembly of the mechanism. Free travel can cause the user to feel that the brake is not sensitive and will also affect the riding experience.

[0004] Therefore, the purpose of this utility model is to actively disclose how to create a brake lever force and preload adjustment device that can be directly installed on a traditional vehicle body, and can adjust the brake sensitivity through simple adjustments without disassembling parts. Furthermore, it can quickly adjust according to the user's different needs for brake stiffness to improve the smoothness of riding, as well as enhance the safety and convenience of riding. Utility Model Content

[0005] The present invention provides a brake arm force and preload adjustment device, which can be directly installed on various vehicle bodies with brake arms without affecting the original vehicle body structure design. After installation, the brake hardness can be adjusted according to different needs to reduce the free travel and achieve the effect of controlling the brake sensitivity, thereby improving the smoothness and safety of riding. In addition, the overall structure is simplified, which can further improve the overall convenience and practicality.

[0006] To achieve the above objectives, this utility model provides a brake arm force and preload adjustment device, applicable to various vehicle bodies equipped with brake arms, tension springs, and master cylinders. It comprises: an adjustment seat body, a set of preload adjustable screws, and a screw rod. One end of the adjustment seat body is connected to the brake arm, and the other end is connected to the master cylinder. The set of preload adjustable screws has a nut, which is locked onto the adjustment seat body to loosen or preload the master cylinder clearance. The screw rod has two nuts, which are locked onto the adjustment seat body on the opposite side corresponding to the preload adjustable screws. One end of the screw rod has an opening for the tension spring to hook into, and the brake arm stiffness is adjusted by loosening or tightening the nuts.

[0007] In a preferred embodiment, the adjusting seat body is preferably made of metal, aluminum, plastic, silicone, rubber, or PVC. Attached Figure Description

[0022] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0023] The following describes embodiments of the present invention with reference to the drawings. It should be noted that the following drawings are simplified schematic diagrams, which are only used to illustrate the basic concept of the present invention. Therefore, the drawings only illustrate the structure related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component are not limited to the drawings and can be changed according to actual design needs, which will be stated in advance.

[0024] First, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The figures show an exploded perspective view, an assembled perspective view, a reference view of the usage state, and a front view of the usage state from another direction, all representing a preferred embodiment of the brake arm force and preload adjustment device of this utility model. As shown in the figures, the brake arm force and preload adjustment device 1 of this utility model is applicable to various vehicle bodies having a brake arm 2, a tension spring 3, and a brake master cylinder 4, and includes: an adjustment seat body 11, a set of preload adjustable screws 12, and a screw 13. One end of the adjusting seat body 11 is connected to the brake arm 2, and the other end is connected to the brake master cylinder 4; a set of preload adjustable screws 12 have a nut 121, and the preload adjustable screws 12 are locked on the adjusting seat body 11 for loosening or tightening the brake master cylinder 4; the screw 13 has two nuts 131, and the screw 13 is locked on the adjusting seat body 11 on the other side corresponding to the preload adjustable screws 12. One end of the screw 13 has an opening 130 for the tension spring 3 to pull into the opening, and the stiffness of the brake arm is adjusted by loosening or tightening the nuts 131.

[0025] In a preferred embodiment, the adjusting seat body 11 is preferably made of metal, aluminum, plastic, silicone, rubber, or plastic-steel. Furthermore, this invention can be installed on any vehicle body with a brake lever (pedal), such as bicycles, road motorcycles, sport motorcycles, cruisers, touring motorcycles, agricultural vehicles, supermotos, adventure vehicles, or off-road vehicles.

[0026] Using the above structure, such as Figure 3 and Figure 4As shown, after assembling the brake arm force and preload adjustment device 1 of this utility model onto the brake arm 2, tension spring 3, and brake master cylinder 4, the preload of the brake master cylinder 4 can be achieved by tightening or loosening the preload adjustment screw 12. Then, by loosening or tightening the nut 131 on the adjusting screw 13, the stiffness of the tension spring 3 can be adjusted, thereby changing the foot pressure on the brake arm 2. Thus, the stiffness of the brake arm 2 can be adjusted to meet different usage requirements.
