Description
Technical field
This utility model relates to disk brake, is specially a kind of disc brake with floating caliper with ventilating system.
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.
Owing to disc brake with floating caliper is that the frictional force by brake block with braking dish is braked, therefore substantial amounts of heat will be produced in braking procedure, life-time service will easily cause the abrasion even inefficacy of brake of brake block, and then badly influence the driving safety of vehicle.
Utility model content
This utility model is intended to provide a kind of disc brake with floating caliper with ventilating system, and brake block is caused abrasion and then the problem having influence on vehicle driving safety by the heat produced to solve braking procedure.
The disc brake with floating caliper with ventilating system in this programme, including caliper and braking dish, caliper float across in braking dish both sides, caliper offers inlet opening and plunger shaft, inlet opening and plunger shaft communicate, piston it is provided with in plunger shaft, piston place is provided with movable brake block, the mating surface of piston and movable brake block is further opened with some louvres, position vertical with louvre on piston is further opened with air vent, louvre communicates with air vent, side relative with plunger shaft on caliper is additionally provided with fixing brake block, fixing brake block and movable brake block lay respectively at the both sides of braking dish.
nullThe principle of this programme is: when the brake is applied，High-pressure brake liquid enters plunger shaft from inlet opening，Entering the high-pressure brake liquid in plunger shaft will promote piston driving activity brake block to move to braking dish direction，Until movable brake block offsets with braking dish，According to active force and counteracting force，Braking dish is by the active force in opposite direction with piston movement to one, piston，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 brake block of both sides all presses on the disc brake rotor，And produce to stop the frictional force of vehicle wheel rotation on a mating，And then realize the braking of wheel，In braking procedure，Substantial amounts of heat will be produced under the effect of frictional force between movable brake block and braking dish，Heat on movable brake block is transferred on piston，And distributed timely and effectively by the louvre on piston and air vent.
The effect of this programme is: by arranging louvre and air vent on piston, louvre and air vent add the contact area of piston and air, the heat being delivered on piston can be distributed timely and effectively, so that the temperature that movable brake block is when braking remains at suitable scope, effectively decrease the abrasion of movable brake block, improve the service life of brake, it is ensured that the driving safety of vehicle.
Further, piston is further opened with the first groove towards the side of inlet opening, first groove communicates with plunger shaft, after high-pressure brake liquid enters plunger shaft from inlet opening, high-pressure brake liquid is partially into the first groove communicated with plunger shaft, when movable brake block transfers heat on piston, the high-pressure brake liquid in the first groove can take away the heat on partial piston, thus improving the heat-sinking capability of piston further.
Further, caliper and the mating surface of piston being additionally provided with elastic seal ring, elastic seal ring can effectively prevent high-pressure brake liquid from leaking from the counterface of caliper and piston.
Further, the outline place of caliper is additionally provided with some radiating ribs with tapering, and radiating ribs can increase the contact area of caliper and air, improves the heat-sinking capability of caliper, and radiating ribs has tapering can make the production of radiating ribs and easy to process.
Further, also include brake-caliper support 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-caliper support, the cylindrical section of guide finger is through the through hole of caliper, and guide finger can to certain guide effect of having moved of caliper.
