Currently used disc brake with floating caliper is to promote piston movement by brake fluid when braking, the one of brake block of piston driving is fitted with brake disc, then brake disc makes caliper move to one active force of caliper again, caliper moves and then drives another block brake block to fit to brake disc, this disc brake with floating caliper two brake block when braking are one in front and one in back fitted to brake disc, the abrasion condition of the disc brake with floating caliper of the most this structure on the one hand two brake block is different, on the other hand braking response speed is slow, and braking ability is poor.
Utility model content
This utility model is intended to provide a kind of disc brake with floating caliper with permanent magnet, and the abrasion condition caused near brake disc during to solve two brake block differences is different and the slow-footed problem of braking response.
The disc brake with floating caliper with permanent magnet in this programme, including caliper and brake disc, caliper float across in brake disc both sides, the first groove is offered on the caliper of brake disc side, the caliper of brake disc opposite side is provided with fixing brake block, first groove is additionally provided with the second groove communicated with the first groove, the bottom land of the second groove is provided with permanent magnet, first groove is provided with can be along the first reciprocating armature of groove, armature offers draw-in groove towards the side of permanent magnet, the opposite side of armature connects movable brake block, magnet exciting coil it is provided with in draw-in groove.
nullThe principle of this programme is: while driver's brake pedal，Electric current it is passed through in Exciting Windings for Transverse Differential Protection，Alive Exciting Windings for Transverse Differential Protection will make armature have magnetic，This magnetic is identical with the magnetic of permanent magnet，The principle repelled each other according to the same sex，Armature is by by an active force towards brake disc direction，Under this active force，Armature drive activity brake block moves to brake disc direction，Meanwhile，Permanent magnet is by an active force deviating from brake disc direction，Owing to caliper is to float，Power suffered by permanent magnet moves driving caliper to the direction away from brake disc，The fixing brake block being now placed in movable brake block opposite side will move to brake disc direction，Under the common effect of armature and permanent magnet，Movable brake block and fixing brake block move to brake disc direction simultaneously，And brake disc is clamped respectively from both sides，And then make brake disc realize braking.
The effect of this programme is: this programme armature and permanent magnet drive activity brake block respectively and fixing brake block move to brake disc simultaneously, on the one hand the inconsistent phenomenon of wearing and tearing caused when movable brake block and fixing brake block are different in tradition disc brake with floating caliper is avoided near brake disc, the most movable brake block and fixing brake block decrease the braking response time near brake disc simultaneously, improve brake efficiency.
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.
Further, being additionally provided with the Brake pad with cushioning effect between caliper and fixing brake block, Brake pad can reduce impact between the two with brake disc when fixing brake block coordinates, and makes cooperation between the two more steady.
Further, magnet exciting coil is direct-flow magnet exciting coil, and direct-flow magnet exciting coil is little compared with the impact of AC excitation coil, noise, and reliability is high.
Further, being additionally provided with some radiating ribs with tapering at the outline of caliper, radiating ribs can increase the contact area of caliper and air, improves the heat-sinking capability of caliper.
