Description

Brake lever

The present invention relates to a brake lever, and more particularly to a brake lever for a disc brake device for a two-wheeled vehicle.

The brake method of the conventional two-wheeled vehicle is basically divided into two types: drum brake and disc brake. On the brake method of the disc brake, the brake lever is used to push the piston head of the brake cylinder, and the brake cylinder is used. The brake oil inside is pressurized to force the brakes on the two sides of the brake disc to make the group, and the two brakes that are forced to move will clamp the brake disc, and the brakes will be used to brake the disc and the brake disc. The friction between them stops the vehicle (resulting in braking effect).

Referring to Figures 1 and 2, the conventional brake lever 1 is mounted on the faucet handle 3 of the vehicle body, and the brake head 1 can be pushed by the brake lever 1 to brake the brake head 2, and the brake is braked. The pull rod 1 includes a fixing base 11 and a pull rod 12. The fixing base 11 is provided with a pivot hole 111 and a braking portion 112. The pivot hole 111 is pivotally connected to the front of the faucet handle 3, and the braking portion 112 can be abutted. The rod 12 is fixed on the rear end of the fixing base 11 for providing a user's grip.

When the brake is to be performed, the pull rod 12 is held to pivot the fixed seat 11 relative to the faucet handle 3, and the braking portion 112 can push the piston head 21 to increase the pressure of the brake cylinder 2 to brake. Actuation; therefore, when braking, the braking portion 112 may wear out due to the friction of the piston head 21, reducing the service life of the brake cylinder 2 and the brake lever 1. Moreover, when the loss reaches a certain level, it will affect the sensitivity of the brake and cause danger to the rider.

Therefore, the present invention intends to solve the above-mentioned prior art defects by reducing the friction loss at the time of braking and improving the braking sensitivity.

Therefore, the main purpose of this creation is to provide a brake lever that can reduce friction loss when braking and can improve brake sensitivity.

In order to achieve the above purpose, the brake lever of the present invention is installed at the handle of the faucet of the vehicle body, and the brake lever can be pushed by pushing the brake lever to brake the brake head, and the brake lever has a lever and a fixing seat is fixed on the rear end of the fixing base for providing a user's grip; the fixing seat is provided with a pivoting hole and a braking portion, and the pivoting hole is pivotally connected to the front of the faucet handle, and the feature is The brake portion is sleeved with a rolling member, and the rolling member is abutted against the piston head, so as to reduce friction between the brake head and the piston head, and improve the sensitivity of the brake.

In a preferred embodiment, the braking portion is provided with two oppositely disposed lugs, and the rolling member is pivotally disposed between the two lugs.

The above-mentioned lug is provided with a shaft hole, and the rolling member is pivotally disposed on the shaft hole.

The rolling element comprises: a sleeve and a shaft barrel, wherein the shaft barrel is inserted into the sleeve, and the shaft barrel is fixed to the shaft hole by riveting.

Other objects, advantages and features of the present invention will be apparent from the following description of the preferred embodiments illustrated herein.

In the following, only the specific examples and detailed descriptions will be provided to enable your review committee to have a better understanding and understanding of the functions and features of this creation:

As shown in FIG. 3 and FIG. 4, the present invention is a brake lever 1 including a fixing base 11 and a pull rod 12, and the pull rod system 12 is fixed at the rear end of the fixing base 11 for providing a user's grip: The front end of the fixing base 11 is provided with a pivot hole 111 and a braking portion 112. The braking portion 112 defines two oppositely disposed lugs 41. The lug 41 is provided with a shaft hole 411 and is sleeved on the lug 41. There is a rolling member 4 which is fastened to the shaft hole 411 by a sleeve 43 through a sleeve 42 and is sleeved between the two lugs 41. .

Referring to FIG. 5 , as shown in FIG. 6 , the pivoting hole 111 pivotally connects the brake lever 1 to the front of the faucet handle 3 , and the sleeve 42 on the rolling member 4 on the braking portion 112 can be placed against the brake. On the piston head 21 on the cylinder 2. When the brake is to be performed, the pull rod 12 is held to pivot the fixed seat 11 relative to the faucet handle 3, and the sleeve 42 on the braking portion 112 can push the piston head 21 in a rolling manner to brake the brake cylinder 2 The pressure is increased to perform the brake actuation; thereby, the rolling member 4 on the braking portion 112 can use the rolling characteristics to push the piston head 21 when braking, thereby reducing friction loss during braking and reducing friction For the sake of this, the brake sensitivity can also be improved, and the brake lever 1 can be operated more smoothly.

In summary, the brake lever 1 of the present invention has the function of reducing the friction loss when braking, and improving the braking sensitivity, thereby improving the service life of the brake cylinder 2 and the brake lever 1, so that the rider can drive more smoothly. And safe.

The above description is by way of a detailed description of the present invention, and is not intended to limit the scope of the present invention. Anyone who is familiar with such a skilled person can understand, and appropriate changes and adjustments will not lose the essence of this creation, and will not deviate from the spirit and scope of this creation.
