Title
(EN) BRAKE CALIPER INCLUDING HEAT PIPES
(FR) ETRIER DE FREIN COMPORTANT DES CALODUCS
Abstract
(EN)
A brake caliper including a caliper body and heat pipes at least partially embedded within the caliper body. The caliper body includes spaced inboard and outboard portions. In addition, at least one of the portions includes piston bores. The caliper body further includes a connector between the inboard and outboard portions whose spacing permits brake pads and a periphery of a brake rotor to be received between the inboard and outboard portions. Also, the brake caliper includes pistons disposed in the piston bores to press the brake pads against the periphery of the brake rotor when brake fluid moves the pistons and the brake pads toward the brake rotor. As the brake pads heat the brake caliper, the heat pipes transfer heat away from the piston bores thereby cooling the brake caliper and brake fluid in, around, or near the piston bores.
(FR)
L’invention concerne un étrier de frein comportant un corps d’étrier et des caloducs au moins en partie encastrés à l’intérieur du corps d’étrier. Le corps d’étrier comporte des parties intérieures et extérieures espacées. En outre, au moins une des parties comporte des trous de piston. Le corps d’étrier comporte par ailleurs un raccord entre les parties intérieures et extérieures dont l’espacement permet de recevoir des plaquettes de frein et une périphérie d’un rotor de frein entre les parties intérieures et extérieures. De même, l’étrier de frein comporte des pistons disposés dans les trous de piston pour presser les plaquettes de frein contre la périphérie du rotor de frein lorsque le fluide de freinage déplace les pistons et les plaquettes de frein en direction du rotor de frein. A mesure que les plaquettes de frein chauffent l’étrier de frein, les caloducs transfèrent la chaleur à distance des trous de piston, ce qui refroidit l’étrier de frein et le fluide de freinage dans, autour, ou près des trous de piston.
