Description
Technical field
This utility model relates to disc brake with floating caliper, is specially a kind of disc brake with floating caliper with automatic compensation function.
Background technology
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 the disc brake with floating caliper with automatic compensation function providing a kind of brake clearance that can make between brake block and braking dish to remain at optimal value.
The disc brake with floating caliper with automatic compensation function in this programme, including caliper and braking dish, braking dish is connected with outside wheel, caliper float across in braking dish both sides, caliper offers inlet opening, inlet opening place is additionally provided with the hydraulic cavities communicated with inlet opening, the piston that can move back and forth it is provided with along hydraulic cavities in hydraulic cavities, piston is provided with projection towards the side of inlet opening, the opposite side of piston is provided with movable brake block, one side relative with movable brake block on caliper is additionally provided with fixing brake block, hydraulic cavities place is additionally provided with drag ring, drag ring outline is pressed on the wall of hydraulic cavities, drag ring Internal periphery and piston mating surface place have certain distance, piston is additionally provided with the shaft block ring pressed with piston.
The principle of this programme is: when wheel is braked by needs, brake fluid enters hydraulic cavities from inlet opening, the brake fluid entering inlet opening promotes piston driving activity brake block to move to braking dish direction, when movable brake block and braking dish offset, according to active force and counteracting force, braking dish is to one, the piston active force in opposite direction with piston movement, piston is made to move round about together with caliper entirety, until the fixing brake block on piston opposite also presses on the disc brake rotor, now the projection on piston and drag ring offset, braking dish realizes braking effect under the effect of both sides brake block.
Due in braking procedure, movable brake block first offsets with braking dish, therefore movable brake block can than fixing brake pads wear more faster, when movable brake block is after using a period of time abrasion occur, again brake, when protruding and drag ring offset, still certain distance is there is also between movable brake block and braking dish, now under the effect of brake fluid, projection makes drag ring overcome the active force between self and hydraulic cavities, drag ring moves to braking dish direction with piston, until movable brake block and braking dish offset, when braking complete piston reset time, shaft block ring on piston and drag ring offset, owing to drag ring moves certain distance, therefore piston will be limited in new position.
The effect of this programme is: by arranging drag ring on hydraulic cavities inwall, when brake clearance increases, drag ring can move corresponding distance, and piston also can drive movable brake block to move corresponding distance under the restriction of drag ring, and this distance is the distance that brake clearance increases, therefore this programme is when brake clearance increases, and can realize the automatic compensation of brake clearance, brake clearance is made to remain at optimal value, it is ensured that the driving safety of vehicle.
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, the cylindrical section of guide finger is through the through hole of caliper, and caliper can have been moved back and forth certain guide effect by guide finger.
Further, fixing between brake block and caliper, be additionally provided with Brake pad, Brake pad can reduce fixing brake block and braking dish in conjunction with time impulsive force.
Further, Brake pad and the mating surface of fixing brake block offer some louvres, when fixing brake block is with the laminating of braking dish, fixing brake block can produce substantial amounts of heat under the effect of frictional force, this heat can be transmitted on the Brake pad fitted with fixing brake block, louvre on Brake pad can increase the contact area of Brake pad and air, makes the heat being delivered to Brake pad place to distribute timely and effectively, so that fixing brake block is all the time at suitable operated within range.
Further, piston is further opened with the first groove, first groove communicates with hydraulic cavities, when activity brake block is with the laminating of braking dish, movable brake block can produce substantial amounts of heat under the effect of frictional force, and this heat can be transmitted on the piston fitted with movable brake block, the brake fluid entering the first groove can take away the partial heat of piston, so that movable brake block can be maintained at suitable temperature range, the abrasion of minimizing activity brake block, improve the reliability of brake.
