Description

Multi-point brake structure of semi-hydraulic brake system

The invention relates to a bicycle braking system, especially a multi-point braking structure of a semi-hydraulic braking system.

Press, the function of the bicycle has been developed from the initial means of transportation into a special-purpose tool. Therefore, the number of people using it is increasing day by day, and the occasions of users are becoming more and more extensive. The functional requirements on the bicycle are becoming more and more strict, especially the braking system for safety considerations. In addition to safe braking performance, sensitive handling is also required. Therefore, new braking mechanisms must be innovated to meet these strict requirements. Therefore, disc brakes have gradually gained attention. Tests have proved that their braking performance is safer and more comfortable than V-type brakes.

Disc brakes can be divided into mechanical disc brakes and hydraulic disc brakes according to the way of braking. Mechanical disc brakes rely on the pulling force of the brake line to make the brake pads in the caliper rub against and clamp the disc to produce a braking effect; hydraulic disc brakes rely on pulling the brake handle to actuate the piston inside to compress the oil.

However, mechanical disc brakes are not only laborious to operate, but also have poor braking stability. The hydraulic disc brake oil pipeline is complicated, so that it is prone to oil leakage, and once the oil pressure tube is broken, the braking effect will be completely lost. In addition, no matter the mechanical disc brake or the hydraulic disc brake, most of them only have one set of pistons. When braking, the set of pistons is used to stop the disc in two points, so the braking effect is good and it is prone to danger.

In view of the above-mentioned shortcomings of the multi-point brake structure of the conventional semi-hydraulic brake system, the author of this work is based on his thoughts and creative ideas. After many discussions, sample tests, and many revisions and improvements, he launched this creation.

The invention provides a multi-point braking structure of a semi-hydraulic brake system, comprising: a caliper, the caliper includes a first caliper body and a second caliper body opposite to each other, the caliper is provided with an accommodation space for disc assembly between the first caliper body and the second caliper body, at least two storage grooves are respectively provided on the sides of the first caliper body and the second caliper body facing the accommodation space, for at least two groups of pistons to slide and accommodate, the first caliper body is provided with an oil chamber and a brake line seat, and the first caliper body is provided with an oil chamber and a brake line seat on the oil chamber A rocker arm is pivoted at the relative position of the opening; an interlocking device, the interlocking device includes an oil pressure pusher and an elastic element, the oil pressure pusher is sleeved in the oil chamber, and the oil pressure pusher is provided with a screw extending out of the oil chamber, the screw passes through the rocker arm to form linkage, the elastic element is installed in the oil chamber, bounces between the bottom of the oil chamber and the oil pressure pusher, and gives the oil pressure pusher The ability to actively reset; Link, and the rocker arm can be driven by the brake line to swing toward the direction of the oil chamber, and then the screw rod can drive the oil pressure pusher to displace toward the bottom of the oil chamber.

The main purpose of creating the multi-point brake structure of the semi-hydraulic brake system is that the brake operation is labor-saving, the brake stability is good, and the oil consumption is small, the maintenance is easy, the manufacturing cost is low, and it is provided with at least two sets of pistons.
