Background technique
Existing hydraulic braking pincers generally comprise caliper, braking plate, piston, and piston promotes braking plate and abuts on the brake disc to realize braking.In high performance vehicle, in brake calipers, often adopt opposed two pistons to promote braking plate respectively traditionally, wherein, braking plate is to be slidingly connected in brake calipers, when brakeless, braking plate is in free state.
Behind brake off, braking plate is not return rapidly with piston but is continued to be attached on the brake disc, separating of braking plate and brake disc mainly is to lean on the elastic force of reed to separate, along with the lengthening in working life, reed elastic force slowly reduces, when vehicle is exercised, brake disc meeting and braking plate produce the friction abnormal sound, thereby the generation noise simultaneously, also can quicken the wearing and tearing to braking plate.
Summary of the invention
The purpose of this utility model is to have above-mentioned problem at existing hydraulic braking pincers, provides a kind of noise free, hydraulic braking simple in structure to clamp.
The purpose of this utility model can realize by following technical proposal: a kind of hydraulic braking pincers, comprise caliper with jaw, in the caliper of the both sides of jaw, be provided with opposed piston cavity, in piston cavity, be provided with piston, be equipped with slidably braking plate on the exterior edge face of piston, above-mentioned braking plate comprises lamellar body and the friction plate that is fixed on the lamellar body, it is characterized in that, be fixed with permanent magnet on the described piston, described lamellar body adopts magnetic material to make.
Have the common hydraulic system that driven plunger moves around in this hydraulic braking pincers in piston cavity, brake disc is between two braking plates.Owing to be fixed with permanent magnet on the piston, the caliper of braking plate adopts magnetic material to make, and braking plate is the jaw place at caliper of being slidingly connected, and therefore, braking plate can be adsorbed on the exterior edge face of piston.After piston promotion braking plate was resisted against on the brake disc, the hydraulic braking pincers were realized braking; After piston was return, braking plate can break away from brake disc under the effect of magnetic force, thereby had eliminated the root that produces noise, secondly, had also eliminated unnecessary friction, had prolonged the working life of braking plate.
In above-mentioned hydraulic braking pincers, described permanent magnet is arranged on the center of piston exterior edge face.Permanent magnet is installed in the center of piston exterior edge face, and permanent magnet at the vertical fulcrum place of braking plate, makes braking plate can braking plate be resetted to the active force of braking plate, reduces the braking plate clamping stagnation.In addition, for the braking plate of different profiles, permanent magnet mounting point difference.
In above-mentioned hydraulic braking pincers, the central part of the exterior edge face of described piston has groove, and above-mentioned permanent magnet fixes in this groove.The braking plate Environmental Conditions is very abominable, high temperature 250 degree, low temperature-40 degree, and perhaps in the silt environment, other Placement all can not satisfy the requirement of product Environmental Conditions.
In above-mentioned hydraulic braking pincers, be provided with seal ring between described piston and the caliper.Between piston and caliper, be provided with seal ring and can prevent to leak, after the braking plate wearing and tearing, can regulate the brake clearance of braking plate simultaneously automatically.
In above-mentioned hydraulic braking pincers, described permanent magnet is Nd-Fe-B permanent magnet or rare-earth iron series permanent magnet.Nd-Fe-B permanent magnet or rare-earth iron series permanent magnet have excellent performance and reasonable price.
In above-mentioned hydraulic braking pincers, described lamellar body and friction plate are connected by bonding mode.
Compared with prior art, this hydraulic braking pincers are installed permanent magnet in the center of the exterior edge face of piston, after piston is return, braking plate can break away from brake disc under the effect of magnetic force, thereby eliminated the root that produces noise, the performance of this product is optimized, secondly, also eliminate unnecessary friction, prolonged the working life of braking plate.
Description of drawings
Fig. 1 is the structural representation of this hydraulic braking pincers.
Among the figure, caliper 1, jaw 11, piston cavity 12, piston 2, exterior edge face 21, groove 22, braking plate 3, lamellar body 31, friction plate 32, permanent magnet 4, seal ring 5, brake disc 6.
Embodiment
Below be specific embodiment of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As shown in Figure 1, this hydraulic braking pincers comprise the hydraulic system that caliper 1, piston 2, braking plate 3, permanent magnet 4 and driven plunger 2 move around, this hydraulic braking pincers are arranged on the brake disc 6, eliminate the noise that the hydraulic braking pincers produce by the magnetic force that 4 pairs of braking plates of permanent magnet 3 produce when braking releasing back vehicle is exercised.
Specifically, the caliper 1 of this hydraulic braking pincers has the jaw 11 of a U-shaped, brake disc 6 can be arranged in jaw 11, in the caliper 1 of the both sides of jaw 11, be provided with opposed piston cavity 12, be provided with piston 2 in piston cavity 12, the hydraulic system in piston cavity 12 and the hydraulic braking pincers is connected, in order to prevent to leak, be provided with seal ring 5 between piston 2 and the caliper 1, sealing circle 5 can also be regulated the brake clearance of braking plate 3 after the braking plate wearing and tearing.
Piston 2 is the outer end near an end of jaw 11, on the exterior edge face 21 of piston 2, braking plate 3 is set, this braking plate 3 is fixed on friction plate 32 on the lamellar body 31 by the lamellar body 31 that adopts magnetic material to make with by bonding mode, and this friction plate 32 is selected copper-based powder material for use.Have sliding motion structure between the lamellar body 31 of braking plate 3 and the caliper 1, this sliding motion structure is common technology, and the glide direction of braking plate 3 is identical with the movement direction of piston 2.Central part in the exterior edge face 21 of piston 2 has groove 22, and permanent magnet 4 fixes in this groove 22.Therefore, permanent magnet 4 is positioned at the center of piston 2 exterior edge faces 21, and like this, in the center of braking plate 3, stressed position the best has reduced the slip resistance of braking plate 3 to the magnetic force of permanent magnet 4 to the force bearing point of braking plate 3.In this example, permanent magnet 4 adopts rare-earth iron series permanent magnet 4.
