Abstract
The invention discloses a floating caliper disc brake with an automatic compensation function. The floating caliper disc brake comprises brake calipers and a brake disc. A liquid inlet is formed in the brake calipers. A hydraulic cavity communicating with the liquid inlet is formed in the liquid inlet. A piston is arranged in the hydraulic cavity. A bulge is formed in one side, facing the liquid inlet, of the piston. A movable brake pad is arranged on the other side of the piston. A fixed brake pad is arranged on one surface, opposite to the movable brake pad, of the brake calipers. A friction ring is arranged at the hydraulic cavity. A shaft retaining ring in compression with the piston is arranged on the piston. The floating caliper disc brake adopting the scheme has the effects that when the brake clearance is increased, the friction ring moves by a corresponding distance, while the piston also drives the movable brake pad to move by the corresponding distance under the restriction of the friction ring, and the corresponding distance is equal to the increased part of the brake clearance. Therefore, when the brake clearance is increased, the automatic compensation of the brake clearance can be realized, and the brake clearance is always kept at an optimal value.
Description
Technical field
The present invention relates to disc brake with floating caliper, be specially a kind of disc brake with floating caliper with automatic compensation function.
Background technique
Caliper disc brake can be divided into by the structural type of brake calipers determines caliper disc and floating caliper type disc two kinds, contrary with disc brake with fixed caliper, the axis of disc brake with floating caliper and radial dimension are all less, can closer to hub for vehicle wheel during layout, therefore disc brake with floating caliper is widely used on car and pick up truck.
Disc brake with floating caliper brakes by the brake slipper of both sides and the frictional force of brake disc, therefore when break in use for some time, brake slipper will there will be certain wearing and tearing, the brake cabin distance caused between brake slipper and brake disc increases by the wearing and tearing of brake slipper, and the brake cabin between brake slipper and brake disc is apart from braking ability being caused to decline when increasing, the serious driving safety that even can have influence on vehicle.
Summary of the invention
The invention is intended to provide a kind of disc brake with floating caliper with automatic compensation function that the brake clearance between brake slipper and brake disc can be made to remain at optimum value.
The disc brake with floating caliper with automatic compensation function in this programme, comprise brake calipers and brake disc, brake disc is connected with outside wheel, brake calipers float across in brake disc both sides, brake calipers offers inlet opening, inlet opening place is also provided with the hydraulic pressure cavity communicated with inlet opening, the piston that can move back and forth along hydraulic pressure cavity is provided with in hydraulic pressure cavity, piston area is provided with projection to the side of inlet opening, the opposite side of piston is provided with movable brake slipper, one side relative with movable brake slipper on brake calipers is also provided with fixing brake slipper, hydraulic pressure cavity place is also provided with friction ring, friction ring external frame is pressed on the wall of hydraulic pressure cavity, friction ring Internal periphery and piston fitting surface place have certain distance, piston is also provided with the shaft block ring pressed with piston.
The principle of this programme is: when needs are braked wheel, brake fluid enters hydraulic pressure cavity from inlet opening, the brake fluid entering inlet opening promotes the movable brake slipper of piston driving and moves to brake disc direction, when movable brake slipper and brake disc offset, according to active force and reaction force, brake disc is to one, piston and piston movement direction opposite effect power, piston is moved round about together with brake calipers entirety, until the fixing brake slipper on piston opposite also presses on the disc brake rotor, projection now on piston and friction ring offset, brake disc realizes braking effect under the effect of both sides brake slipper.
Due in braking process, movable brake slipper first offsets with brake disc, therefore movable brake slipper can be faster than fixing brake pads wear, when movable brake slipper is after wearing and tearing appear in use a period of time, again brake, when protruding and friction ring offset, still certain distance is also there is between movable brake slipper and brake disc, now under the effect of brake fluid, projection makes friction ring overcome active force between self and hydraulic pressure cavity, friction ring moves to brake disc direction with piston, until movable brake slipper and brake disc offset, when braking complete piston reset time, shaft block ring on piston and friction ring offset, because friction ring moves certain distance, therefore piston will be limited in new position.
The effect of this programme is: by arranging friction ring on hydraulic pressure cavity inwall, when brake clearance increases, friction ring can move corresponding distance, and piston also can drive movable brake slipper to move corresponding distance under the restriction of friction ring, and this distance is the distance that brake clearance increases, therefore this programme is when brake clearance increases, and can realize the auto-compensation of brake clearance, make brake clearance remain at optimum value, ensure that the driving safety of vehicle.
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, the cylindrical section of guide finger passes the through hole of brake calipers, and guide finger can play certain leading role to the to-and-fro motion of brake calipers.
Further, fixing between brake slipper and brake calipers, be also provided with brake shoe, brake shoe can reduce fixing brake slipper and brake disc in conjunction with time impact force.
Further, the fitting surface of brake shoe and fixing brake slipper offers some radiation holes, when fixing brake slipper and brake disc are fitted, fixing brake slipper can produce a large amount of heats under the effect of frictional force, this heat can be transmitted on the brake shoe of fitting with fixing brake slipper, radiation hole on brake shoe can increase the area of contact of brake shoe and air, and the heat being delivered to brake shoe place can be distributed timely and effectively, thus makes fixing brake slipper all the time at suitable operated within range.
Further, piston also offers the first groove, first groove communicates with hydraulic pressure cavity, when movable brake slipper and brake disc are fitted, movable brake slipper can produce a large amount of heats under the effect of frictional force, and this heat can be transmitted on the piston of fitting with movable brake slipper, the brake fluid entering the first groove can take away the partial heat of piston, thus making movable brake slipper can remain on suitable temperature range, the wearing and tearing of the brake slipper that takes in sail, improve the reliability of break.
