Description

Modular brake caliper

This creation is a brake caliper applied to the brake system of a vehicle, especially a modular brake caliper.

Most of the brake systems of today's vehicles are hydraulically pumped by a brake pump, so that the pistons in the brake calipers at the axles are pressed against the brake shoes by the hydraulic pressure, and are clamped and rotated by the brake shoes. The disc is so that the brake disc and the disc are rubbed against each other to achieve the effect of braking.

The brake caliper of the present invention comprises a clamp seat, a plurality of pistons and a second brake piece, wherein the clamp seat internally forms an actuation space, a plurality of chambers and a flow passage respectively connecting the plurality of chambers, wherein the plurality of chambers are respectively distributed On the two sides of the actuating space, the plurality of pistons are respectively movably disposed in the plurality of chambers, and the two brake shoes are respectively disposed in the jaw seat oppositely and movably, and are located in the operating space. The outer sides of the sheets are respectively attached to the pistons on the same side, and the flow passages are connected to the brake pump.

However, today's different specifications of vehicles have different requirements for braking force. Among them, according to the Pascal principle, the braking force of the vehicle's braking system can vary according to the size and number of pistons in the brake calipers. When the size of the piston in the caliper is larger or the number is larger, the braking force of the vehicle's braking system can increase the vehicle's braking force; in contrast, when the piston in the brake caliper is smaller or smaller, the vehicle is braked. The vehicle's driving force can be reduced.

However, the chamber inside the clamp of the brake caliper is fixed in size, and can only correspond to a single-size piston installation. When the vehicle needs to further adjust the vehicle's braking force in response to the power increase, the brake caliper cannot be used for different sizes. The piston, and it is necessary to replace the entire set of brake calipers.

In addition, most of today's brake calipers are made of aluminum alloy. After the driver is driving the vehicle, the local temperature of the internal components of the brake system may be higher than 250 °C, which causes the aluminum alloy brake caliper to deform, resulting in braking force. Attenuation, even the uneven force of the left and right rims, resulting in problems such as jitter, oil leakage and uneven wear of the brakes.

The main purpose of this creation is to provide a modular brake caliper, which aims to improve the size of the piston inside the brake caliper of today, and it is not possible to perform partial replacement according to the vehicle's demand for braking force, and the whole group must be replaced.
