Description
Technical field
This utility model relates to disk brake, is specially a kind of disc brake with fixed caliper with cooling duct.
Background technology
Rotation element in disk brake friction pair is with the rosette of end face work, is called braking dish.Friction element clamps braking dish from both sides and produces braking.Retaining element then has various structures form, and disk brake generally can be divided into caliper disc and complete-disc two class.
Spot-type disc brake can be divided into by the structural shape of caliper determines caliper disc and floating caliper type disc two kinds, disc brake with fixed caliper is when braking, brake block clamps braking dish respectively from both sides, the braking of braking dish is realized under the effect of both frictional force, therefore disc brake with fixed caliper will produce substantial amounts of heat in braking procedure under the effect of frictional force, if this heat can not distribute in time, will result in the abrasion of brake block, will result in the inefficacy of brake time serious, have influence on the driving safety of vehicle.
Utility model content
This utility model is intended to provide a kind of disc brake with fixed caliper with cooling duct, can not distribute the brake wear caused in time solving heat in braking procedure, the even problem of misfunctioning of brake.
The disc brake with fixed caliper with cooling duct in this programme, including caliper and braking dish, caliper is fixed in outside vehicle bridge, caliper is across in described braking dish both sides, caliper offers oil-in and flow channel for liquids, oil-in and flow channel for liquids communicate, axially symmetric centered by braking dish on flow channel for liquids it is provided with two pistons, piston is provided with brake block towards braking dish side, piston is further opened with cooling duct, both sides, cooling duct all communicate with flow channel for liquids, and the side of cooling duct is additionally provided with the check valve preventing adverse current.
nullThe principle of this programme is: when braking dish is braked by needs，Brake fluid enters flow channel for liquids from the oil-in of caliper，Entering the brake fluid in flow channel for liquids promotes the piston of braking dish both sides to move to direction, braking dish place，Piston drives the brake block linked together with piston jointly to move to direction, braking dish place while motion，Until the brake block of both sides and braking dish are close together，While brake fluid promotes piston movement，The cooling duct that the brake fluid of part also will enter in piston，Under the effect of cooling duct check valve，Brake fluid has the side of check valve to enter from cooling duct，It is returned in flow channel for liquids from the opposite side of cooling duct，When brake block is close to braking dish，Under the effect of both frictional force，The speed of braking dish slows down and is decreased until stopping slowly，In the process，Brake block will produce substantial amounts of heat under the effect of frictional force，The major part of these heats is transferred into the piston place connected between brake block，Now the brake fluid in piston will be taken away the heat being delivered to piston timely in the process of flowing.
This programme provides the benefit that: by arranging cooling duct in piston, in cooling duct, the flowing of brake fluid is taken away timely and effectively brake block being delivered to the heat at piston place, so that brake block can be maintained at suitable temperature in braking procedure, simultaneously from cooling duct, the brake fluid carrying heat out will produce higher pressure, and then make the laminating of brake block and braking dish tightr, braking effect is better, therefore the heat that can take away brake in time of the brake of this programme is adopted, prevent the abrasion of brake block, thus ensure that the stability of brake operation performance.
Further, in order to make brake block can separate with braking dish in time after completing braking, being provided with extension spring between piston and caliper, extension spring one end and caliper offset, and the extension spring other end and piston offset.
Further, piston is provided with projection towards braking dish side, and projection can offset with caliper under the effect of described extension spring, and upon completion of the braking, extension spring drives brake block to separate with braking dish, until the projection of piston and caliper end face offset.
Further, in order to caliper is fixed, removing stress concentrations, the phenomenon such as burr that caliper causes in the course of processing, caliper passes through to weld to be fixed with outside vehicle bridge, and the end of caliper is additionally provided with the circular arc chamfering preventing stress from concentrating simultaneously.
