Description
Technical field
The present invention relates to disk brake, a kind of disc brake with floating caliper with cooling duct.
Background technology
Disc brake with floating caliper is a kind of vitals in brake system of car, and its structure has generally comprised caliper, brake disc, brake block and hydraulic system, and brake disc is fixedly installed in vehicle bridge, rotates with wheel.When braking, HYDRAULIC CONTROL SYSTEM brake block crimp on the disc brake rotor, utilize brake block that the frictional resistance of brake disc is realized the deceleration to wheel and braking.
Brake block on disc brake with floating caliper is divided into movable brake block and fixing brake block, movable brake block is arranged on piston, under the effect of brake fluid, piston can drive movable brake block to move to brake disc direction, and fix brake block and be typically directly fixed on caliper, fixing brake block is when being braked, fixing frictional force between brake block and brake disc will make fixing brake block produce substantial amounts of heat, fixing brake block will be made the most easily to damage if this heat can not distribute timely and effectively.The fixing brake block of the disc brake with floating caliper of this version once damages, and removes the most difficult.
Summary of the invention
The invention is intended to provide a kind of disc brake with floating caliper with cooling duct, can not distribute, with the fixing brake block heat of solution, the problem causing damaging in time.
The disc brake with floating caliper with cooling duct in this programme, including caliper and brake disc, caliper float across the both sides in brake disc, plunger shaft and inlet opening is offered on the caliper of brake disc side, the caliper of brake disc opposite side is provided with fixing brake block, plunger shaft communicates with inlet opening, piston it is provided with in plunger shaft, piston is provided with movable brake block towards the side of brake disc, caliper is further opened with across the cooling duct in brake disc both sides, cooling duct includes the feed pathway near fixing brake block side and the liquid outlet channel of opposite side, feed pathway and liquid outlet channel all communicate with plunger shaft, feed pathway is provided with check valve with the place of communicating of plunger shaft.
The operation principle of this programme is: when being braked, brake fluid enters plunger shaft from inlet opening, under the effect of the brake fluid in plunger shaft, piston driving activity brake block moves to the direction of brake disc, when moving to movable brake block and offseting with brake disc, according to active force and counteracting force, brake disc will be to one opposite effect power of piston, piston is made to move round about together with caliper entirety, until the fixing brake block on piston opposite also presses on the disc brake rotor, now the brake block of both sides all presses on the disc brake rotor, brake block clamping brake disc also produces the frictional force stoping vehicle wheel rotation on a mating, and then realize the braking of wheel.
When being braked, under the effect of check valve, the brake fluid part entering plunger shaft will enter in feed pathway, brake fluid flows through at fixing brake block along feed pathway, last flowing out in liquid outlet channel, the fixing heat produced between brake block and brake disc will be taken away by flowing through the brake fluid of feed pathway.
The effect of this programme is: the heat that fixing brake disc produces is distributed timely and effectively by this programme by flowing through the brake fluid in feed pathway, so that fixing brake block can be maintained at suitable temperature all the time, it is greatly prolonged the service life of fixing brake block.
Further, fixing and be additionally provided with Brake pad between brake block and caliper, Brake pad can effectively reduce impulsive force when fixing brake block is fitted with brake disc.
Further, piston is additionally provided with elastic seal ring with coordinating of caliper at face, on the one hand elastic seal ring can prevent the face leakage that brake fluid coordinates with caliper from piston, and on the other hand the elasticity of elastic seal ring can make piston drive brake block to separate with brake disc in time upon completion of the braking.
Further, also include brake holder and guide finger, caliper offers through hole, guide finger includes thread segment and cylindrical section, the thread segment of guide finger is threadeded with brake holder, and the cylindrical section of guide finger is through the through hole of caliper, and guide finger has certain guide effect to the motion of caliper.
