The disc brake with floating caliper of current use is promote piston movement by brake fluid when braking, piston driving wherein one piece of brake slipper and brake disc is fitted, then brake disc makes brake calipers move to brake calipers active force again, brake calipers moves and then drives another block brake slipper to fit to brake disc, this disc brake with floating caliper two brake slipper when braking one in front and one in back are fitted to brake disc, therefore the abrasion condition of disc brake with floating caliper one side two brake slipper of this structure is different, braking response speed is slow on the other hand, and braking ability is poor.
Summary of the invention
The invention is intended to provide a kind of disc brake with floating caliper with permanent magnet, with solve two brake slipper different time the abrasion condition that causes near the brake disc different and slow-footed problem of braking response.
The disc brake with floating caliper with permanent magnet in this programme, comprise brake calipers and brake disc, brake calipers float across in brake disc both sides, the brake calipers of brake disc side offers the first groove, the brake calipers of brake disc opposite side is provided with fixing brake slipper, first groove is also 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 along the reciprocating armature of the first groove, armature offers draw-in groove towards the side of permanent magnet, the opposite side of armature is connected with movable brake slipper, field coil is provided with in draw-in groove.
The principle of this programme is: when driver steps on brake petal while, electric current is passed in exciting winding, alive exciting winding will make armature have magnetic, the Magnetic Phase of this magnetic and permanent magnet is same, according to the principle of two like magnetic poles repel each other, armature will be subject to an active force towards brake disc direction, under this active force, armature drive activity brake slipper moves to brake disc direction, meanwhile, permanent magnet is subject to the active force that is deviated from brake disc direction, because brake calipers is floating, drive brake calipers moves to the direction away from brake disc by the power suffered by permanent magnet, the fixing brake slipper being now positioned at movable brake slipper opposite side will move to brake disc direction, under the acting in conjunction of armature and permanent magnet, movable brake slipper and fixing brake slipper move to brake disc direction simultaneously, and clamp brake disc respectively from both sides, and then make brake disc realize braking.
The effect of this programme is: this programme armature and permanent magnet respectively drive activity brake slipper and fixing brake slipper move to brake disc simultaneously, avoid on the one hand movable brake slipper in traditional disc brake with floating caliper different with fixing brake slipper time the wearing and tearing that cause near brake disc inconsistent phenomenons, movable brake slipper and fixing brake slipper decrease the braking response time near brake disc simultaneously on the other hand, improve Braking efficiency.
Further, also comprise brake holder and guide finger, brake calipers offers through hole, guide finger comprises thread section and cylindrical section, the thread section of guide finger is threaded with brake holder, and the cylindrical section of guide finger passes the through hole of brake calipers, and the motion of guide finger to brake calipers has certain leading role.
Further, be also provided with the brake shoe with buffer function between brake calipers and fixing brake slipper, brake shoe can reduce impact between the two when fixing brake slipper coordinates with brake disc, make cooperation between the two more steady.
Further, field 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, the external frame place of brake calipers is also provided with some radiating fin with tapering, and radiating fin can increase the area of contact of brake calipers and air, improves the heat dissipation potential of brake calipers.
