Description
Technical field
This utility model relates to disc brake with floating caliper, is specially a kind of disc brake with floating caliper with autocompensation installation。
Background technology
Spot-type disc brake is the one of disk brake。Its rotation element is with the rosette of end face work, it is called braking dish, retaining element is the brake block of the little brake pad of work area and its metal backing composition, these brake block and actuate device and be incorporated in the clamp-shaped support of braking dish both sides, being generically and collectively referred to as caliper, braking dish and caliper together constitute spot-type disc brake。
Spot-type disc brake can be divided into by the structural shape of caliper determines caliper disc and floating caliper type disc two kinds, contrary with disc brake with fixed caliper, the axially and radially size of disc brake with floating caliper is all less, can closer to hub for vehicle wheel during layout, therefore disc brake with floating caliper is widely used on car and pickup truck。
The frictional force that disc brake with floating caliper is the brake block by both sides and braking dish is braked, therefore when brake in use for some time, brake block is it would appear that certain abrasion, the abrasion of brake block by the brake cabin that causes between brake block and braking dish from increase, and the brake cabin between brake block and braking dish is from causing that braking ability declines when increasing, the serious driving safety even influencing whether vehicle。
Utility model content
This utility model is intended to provide a kind of disc brake with floating caliper with autocompensation installation, declines with the excessive braking ability caused of the brake clearance of brake block and braking dish after solving brake pads wear, the problem even affecting vehicle driving safety。
The disc brake with floating caliper with autocompensation installation in this programme, including caliper and braking dish, braking dish is fixed on outside wheel, caliper is across in braking dish both sides and can move axially along braking dish, caliper offers fuel feed hole and plunger shaft, fuel feed hole communicates with plunger shaft, piston it is provided with in plunger shaft, piston place is provided with movable brake block, caliper is provided with fixing brake block with movable brake block opposite side, also include adjusting rod, adjusting rod includes smooth section and thread segment, the thread segment of adjusting rod is connected with caliper, piston is provided with the first groove and the second groove, first groove and the second groove communicate, the smooth section of adjusting rod is provided with circlip for shaft, circlip for shaft is pressed on the smooth section of adjusting rod, the second groove on piston is further opened with draw-in groove, draw-in groove place is provided with circlip for hole, first groove is additionally provided with extension spring, extension spring one end and the first groove offset, the extension spring other end and adjusting rod offset。
The principle of this programme is: when braking dish is braked by needs, brake fluid enters plunger shaft from fuel feed hole, the piston being positioned at plunger shaft overcomes the active force of extension spring drive activity brake block to move to direction, braking dish place under the effect of brake fluid, when movable brake block presses with braking dish, circlip for hole on piston just offsets with the circlip for shaft on adjusting rod, meanwhile movable brake block under the effect of brake fluid by one, the braking dish active force along movable brake block moving direction, according to active force and counteracting force, braking dish will give movable one contrary power of brake block, this active force will make piston move round about together with caliper, until fixing brake block also presses on the disc brake rotor, now the brake block of both sides presses braking dish simultaneously, thus realizing the braking action of braking dish。
When movable brake block is after using a period of time abrasion occur, brake clearance between movable brake block and braking dish will increase, when being again braked, when the circlip for shaft on the circlip for hole on piston with adjusting rod offsets, gap is still suffered between movable brake block and braking dish, now under the effect of brake fluid, the active force of circlip for shaft will be made circlip for shaft overcome the active force between itself and adjusting rod by circlip for hole, and then make piston continue to move to direction, braking dish place together with circlip for shaft, until movable brake block and braking dish offset, after braking completes, piston back moves under the effect of extension spring, owing to circlip for shaft and adjusting rod are tight fits, so time circlip for shaft will remain in new invariant position, the distance that circlip for shaft moves is exactly the braking distance increased between movable brake block and braking dish, extension spring drives piston to carry out resetting until the second groove of piston offsets with shaft block ring, therefore piston move the distance identical with circlip for shaft together with by same movable brake block, so that the braking distance between movable brake block and braking dish remains constant。
The effect of this programme is: when the braking distance between movable brake block and braking dish increases, it is positioned at the circlip for shaft on adjusting rod and can automatically move identical distance, and circlip for shaft can make piston move identical distance together with movable brake block, thus braking distance remains constant between realization activity brake block and braking dish, improve the reliability of brake, it is ensured that the driving safety of vehicle。
Further, the smooth section of adjusting rod is provided with projection, position when the mobile extreme position of circlip for shaft is it with protruding offseting, when circlip for shaft offsets with projection, it is the threshold limit value that movable brake block can wear and tear, now in order to ensure the reliability of braking, the replacing of movable brake block should be carried out。
Further, piston is provided with sealing ring with the caliper place of cooperation, caliper is additionally provided with some radiating ribs, radiating ribs has tapering, and sealing ring is for preventing the leakage of brake fluid, and the radiating ribs on caliper can increase the area of dissipation of whole brake, the heat produced in drag friction process is made to distribute in time, the temperature being unlikely to make brake is too high, and the convenience in order to produce and process, makes the shape with certain tapering by radiating ribs simultaneously。
Further, for the guiding that the motion offer to caliper is certain, also including brake-caliper support and guide finger, caliper offers through hole, guide finger is also threadeded with brake-caliper support through through hole。
