Description
Technical field
The present invention relates to disk type braker, be specially a kind of disc brake with floating caliper with ventilation system.
Background technique
Caliper disc brake is the one of disk type braker.Its rotatable member is with the rosette of end face work, be called brake disc, fixed element is the brake slipper that the little brake pad of work area and its metal backing form, these brake slipper and actuation gear thereof are all contained in the clamp-shaped support across brake disc both sides, be generically and collectively referred to as brake calipers, brake disc and brake calipers together constitute caliper disc brake.
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.
Because disc brake with floating caliper brakes by the frictional force of brake slipper and brake disc, therefore a large amount of heats will be produced in braking process, Long-Time Service will be easy to the wearing and tearing even inefficacy of break that cause brake slipper, and then badly influences the driving safety of vehicle.
Summary of the invention
The invention is intended to provide a kind of disc brake with floating caliper with ventilation system, the heat produced to solve braking process causes wearing and tearing to brake slipper, and then has influence on the problem of vehicle driving safety.
The disc brake with floating caliper with ventilation system in this programme, comprise brake calipers and brake disc, brake calipers float across in brake disc both sides, brake calipers offers inlet opening and piston cavity, inlet opening and piston cavity communicate, piston is provided with in piston cavity, piston place is provided with movable brake slipper, the fitting surface of piston and movable brake slipper also offers some radiation holes, position vertical with radiation hole on piston also offers vent hole, radiation hole communicates with vent hole, side relative with piston cavity on brake calipers is also provided with fixing brake slipper, fixing brake slipper and movable brake slipper lay respectively at the both sides of brake disc.
The principle of this programme is: when the brake is applied, high-pressure brake liquid enters piston cavity from inlet opening, the high-pressure brake liquid entered in piston cavity will promote the movable brake slipper of piston driving and move to brake disc direction, until movable brake slipper and brake disc offset, according to active force and reaction force, brake disc will 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, now the brake slipper of both sides all presses on the disc brake rotor, and produce the frictional force stoping vehicle wheel rotation on a mating, and then realize the braking of wheel, in braking process, a large amount of heats will be produced under the effect of frictional force between movable brake slipper and brake disc, heat on movable brake slipper will be delivered on piston, and distributed timely and effectively by the radiation hole on piston and vent hole.
The effect of this programme is: by arranging radiation hole and vent hole on piston, radiation hole and vent hole add the area of contact of piston and air, the heat be delivered on piston can be distributed timely and effectively, thus make the temperature of movable brake slipper when braking remain at suitable scope, effectively decrease the wearing and tearing of movable brake slipper, improve the working life of break, ensure that the driving safety of vehicle.
Further, piston area also offers the first groove to the side of inlet opening, first groove communicates with piston cavity, after high-pressure brake liquid enters piston cavity from inlet opening, high-pressure brake liquid part enters the first groove communicated with piston cavity, when heat is delivered on piston by movable brake slipper, the high-pressure brake liquid in the first groove can take away the heat on partial piston, thus improves the heat dissipation potential of piston further.
Further, the fitting surface of brake calipers and piston is also provided with elastic seal ring, elastic seal ring can effectively prevent high-pressure brake liquid from leaking from the counterface of brake calipers and piston.
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, and radiating fin has tapering can make the production of radiating fin and easy to process.
Further, also comprise brake-caliper support 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-caliper support, the cylindrical section of guide finger passes the through hole of brake calipers, and guide finger can play certain leading role to the motion of brake calipers.
