Description
Technical field
This utility model relates to disk brake, is specially a kind of disc brake with fixed caliper with tapered configuration.
Background technology
Automotive brake is an important device in brake system of car, is most important safety member on automobile, and the braking ability of automobile directly affects the driving safety of automobile.
Existing automotive brake mostly is disk brake, and disk brake, when braking, is realized braking by HYDRAULIC CONTROL SYSTEM brake block with the friction of braking dish.Disc brake with fixed caliper is a kind of conventional disk brake, and disc brake with fixed caliper is with its stable work in work, and heat-sinking capability is strong and is widely used on various pickup truck and car.
Disc brake with fixed caliper conventional at present includes caliper and braking dish, caliper is across in braking dish both sides, caliper is arranged with two pistons centered by braking dish, this disc brake with fixed caliper is when braking, brake fluid would span across in braking dish both sides, the piston of braking dish both sides drives brake block to fit on the disc brake rotor under the effect of brake fluid, the path of this disc brake with fixed caliper brake fluid is longer, therefore to ensure that the piston place of braking dish both sides is respectively provided with enough active forces, hydraulic system must produce the brake fluid that pressure is sufficiently large, this will cause that the structure of whole brakes becomes complicated, working stability performance will reduce.
Utility model content
This utility model is intended to provide a kind of disc brake with fixed caliper with tapered configuration that just can meet brake demand with the brake fluid of less pressure.
The disc brake with fixed caliper with tapered configuration in this programme, including braking dish with across the caliper in braking dish both sides, caliper is fixing with outside vehicle frame to be connected, the middle part of caliper is additionally provided with inlet opening, inlet opening is symmetrically arranged on two with flow channel for liquids, flow channel for liquids has tapering, the big end of flow channel for liquids communicates with inlet opening, the small end of flow channel for liquids is communicated with plunger shaft, plunger shaft also has certain tapering, plunger shaft is towards the small end that side is tapered configuration of braking dish, piston it is additionally provided with in plunger shaft, piston has the tapering identical with plunger shaft, it is additionally provided with brake block towards the side of braking dish at piston.
nullThe principle of this programme is: during braking，Brake fluid respectively enters from inlet opening in the flow channel for liquids of both sides，Owing to flow channel for liquids is gradually reduced in the cross section of brake fluid direction of advance，Therefore brake fluid is gradually increased at speed and the pressure of direction of advance，When brake fluid enters in plunger shaft through flow channel for liquids，Brake fluid promotes the piston driving brake block in plunger shaft to move to braking dish direction，Owing to plunger shaft and piston are respectively provided with certain tapering，Plunger shaft is identical to the horizontal force force direction of piston with brake fluid to the horizontal component of the normal force of piston，The active force in the practical level direction that therefore piston is subject to is more than the brake fluid active force to piston horizontal direction，The combined effect power to piston in plunger shaft and brake fluid，Piston driving brake block is close to braking dish，Until the brake block of braking dish both sides is fitted with braking dish simultaneously，Braking dish is under the frictional force effect of both sides brake block，Braking dish realizes braking effect.
The effect of this programme is: 1, by inlet opening is arranged on the middle part of caliper, flow channel for liquids is designed to the tapered configuration being gradually reduced in brake fluid direction of advance cross section simultaneously, shorten the fluid path of brake fluid on the one hand, brake fluid is made constantly to realize supercharging and speed-raising in direction of advance on the other hand, so that the low hydraulic brake fluid that hydraulic system provides can gradually become high-pressure brake liquid, reduce the requirement to hydraulic system.2, by plunger shaft is become the version with identical tapering with plunger designs, when brake fluid promotes piston to move, the horizontal component of piston normal force will be superimposed upon on the brake fluid horizontal applied force to piston by plunger shaft in the same direction, thus reduce further the pressure demand to brake fluid.In conjunction with 1, the effect of 2, this programme is compared with tradition disc brake with fixed caliper, it is only necessary to hydraulic system provides the brake fluid of less pressure that piston just can be made to obtain bigger active force, and then makes piston driving brake block realize near braking dish braking.Therefore adopting the disc brake with fixed caliper of this programme, the structure of whole brakes can be made to become simpler, service behaviour is also more reliable and more stable.
Further, piston is additionally provided with the first groove towards the side of flow channel for liquids, and the first groove communicates with flow channel for liquids, when braking, flows into the brake fluid in the first groove and can take away the partial heat at piston place, piston plays certain cooling effect.
Further, in order to effectively reduce the burr of caliper surrounding, it is prevented that the stress of caliper surrounding is concentrated, and the surrounding of caliper has the circular arc chamfering preventing stress from concentrating.
Further, in order to facilitate the installation that coordinates of brake block and piston, piston and brake block mating surface are additionally provided with positioning convex.
Accompanying drawing explanation
