Description
Technical field
The utility model relates to a kind of automobile brake pincers.
Background technique
The automobile service brake is by the hydraulic pressure power transmission, and can simply be interpreted as at the brake petal place has an oil hydraulic cylinder and the less piston of diameter, as injector, promote hydraulic oil by piston, make hydraulic oil produce certain pressure,, pressure is increased again by the brake vacuum pump; At this moment the hydraulic fluid pressure in the pipe is very high, by indusion tube with hydraulic pressure transfer to the oil hydraulic cylinder of clamp, hydraulic oil promotes the bigger piston forward of diameter and advances in the limited space of oil hydraulic cylinder, according to pascal's principle, this moment, braking force increased once more.Piston promotes brake shoe again and brake disc produces friction, reaches the purpose of braking, the working principle of a whole set of brake fluid pressure part that Here it is.
The clamp of this form of clamp type of floating is the most commonly used, and structure is the simplest.Hydraulic oil is between piston and the clamp, and hydraulic oil acts on piston forward when advancing, and under the effect of reaction force, promotes clamp simultaneously and advances to the opposite direction of piston motion.Like this, the braking force that both direction is opposite just in time acts on the brake disc both sides, clamps brake disc, thereby reaches the purpose of braking.
Brake calipers drags the wear extent that moment directly influences friction plate and brake disc under non-braking state, excessive drags the heel and toe wear that moment can cause friction plate and brake disc and then influence braking travelling comfort and braking component life-span; Simultaneously excessive drag the energy dissipation that moment can improve non-braking state, reduce the fuel economy of vehicle.
The model utility content
The purpose of this utility model is to provide a kind of automobile brake pincers that can overcome above-mentioned shortcoming.
A kind of automobile brake pincers of the present utility model comprise outside friction disc, interior friction plate, support, guiding reed, active guide finger, passive guide finger, caliper, piston and seal ring.Wherein, the guiding reed connects outside friction disc and interior friction plate; Support is held guiding reed, outside friction disc and interior friction plate, and is connected with caliper with passive guide finger by the active guide finger; Between interior friction plate and the caliper piston is housed; Seal by seal ring between piston and the caliper.
Preferably, described caliper is made by the material with big rigidity.
Preferably, the sectional shape of the shape of the seal groove of piston and seal ring matches.
Preferably, the guide surface of described active guide finger has three guide surfaces.
Preferably, the end of described passive guide finger has rubber washer.
Preferably, the guiding reed matches with interior friction plate and outside friction disc.
Advantage of the present utility model is, brake calipers with said structure has lower system's internal friction and bigger piston returning place force, under the prerequisite that guarantees braking ability, significantly reduced dragging moment, can effectively reduce the heel and toe wear of friction plate and brake disc, improved the braking travelling comfort; Effectively reduce the energy dissipation of non-braking state simultaneously, improve the car load fuel economy.
