Description
Technical field
The present invention relates to disk type braker, be specially a kind of disc brake with fixed caliper with tapered configuration.
Background technique
Automotive brake is an important device in brake system of car, and be most important safety member on automobile, the braking ability of automobile directly affects the driving safety of automobile.
Existing automotive brake mostly is disk type braker, and disk type braker, when braking, is rubbed by HYDRAULIC CONTROL SYSTEM brake slipper and brake disc to realize braking.Disc brake with fixed caliper is a kind of conventional disk type braker, and disc brake with fixed caliper is with its stable work in work, and heat dissipation potential is strong and be widely used on various pick up truck and car.
Disc brake with fixed caliper conventional at present comprises brake calipers and brake disc, brake calipers is across in brake disc both sides, brake calipers is arranged with two pistons centered by brake disc, this disc brake with fixed caliper is when braking, brake fluid will across in brake disc both sides, the piston of brake disc both sides drives brake slipper 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 in order to ensure that the piston place of brake disc both sides all has enough active forces, hydraulic system must produce the enough large brake fluid of pressure, this will cause the structure of whole braking system to become complicated, working stability performance will reduce.
Summary of the invention
The invention is intended to provide a kind of disc brake with fixed caliper that just can meet the band tapered configuration of break demand with the brake fluid of less pressure.
The disc brake with fixed caliper of the band tapered configuration in this programme, comprise brake disc and across the brake calipers in brake disc both sides, brake calipers is fixedly connected with outside vehicle frame, the middle part of brake calipers is also provided with inlet opening, inlet opening bilateral symmetry is provided with flow channel for liquids, flow channel for liquids has tapering, the large end of flow channel for liquids communicates with inlet opening, the small end of flow channel for liquids is communicated with piston cavity, piston cavity also has certain tapering, piston cavity is the small end of tapered configuration towards the side of brake disc, also piston is provided with in piston cavity, piston has the tapering identical with piston cavity, also brake slipper is provided with to the side of brake disc at piston area.
The principle of this programme is: during braking, brake fluid enters in the flow channel for liquids of both sides respectively from inlet opening, because the cross section of flow channel for liquids in brake fluid direction of advance reduces gradually, therefore brake fluid increases gradually in the speed of direction of advance and pressure, when brake fluid enters in piston cavity through flow channel for liquids, the piston driving brake slipper that brake fluid promotes in piston cavity moves to brake disc direction, because piston cavity and piston all have certain tapering, piston cavity is identical with the horizontal force force direction of brake fluid to piston to the horizontal component of the normal force of piston, therefore the active force in real standard direction that piston is subject to is greater than the active force of brake fluid to piston substantially horizontal, at piston cavity and brake fluid to the acting in conjunction power of piston, piston driving brake slipper is close to brake disc, until the brake slipper of brake disc both sides is fitted with brake disc simultaneously, brake disc is under the frictional force effect of both sides brake slipper, brake disc realizes braking effect.
The effect of this programme is: 1, by inlet opening being arranged on the middle part of brake calipers, flow channel for liquids is designed to the tapered configuration reduced gradually 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, thus the low hydraulic brake fluid making hydraulic system provide can gradually become high-pressure brake liquid, reduces the requirement to hydraulic system.2, by becoming to have the structural type of identical tapering by piston cavity and plunger designs, when brake fluid promotion piston moves, piston cavity will be superimposed upon brake fluid on the horizontal applied force of piston in the same way to the horizontal component of piston normal force, thus reduce further the pressure demand to brake fluid.In conjunction with 1, the effect of 2, this programme, compared with traditional disc brake with fixed caliper, only needs hydraulic system to provide the brake fluid of less pressure that piston just can be made to obtain larger active force, and then makes piston driving brake slipper realize braking near brake disc.Therefore adopt the disc brake with fixed caliper of this programme, the structure of whole braking system can be made to become more simple, and service behaviour is also more reliable and more stable.
Further, piston area is also provided with the first groove to the side of flow channel for liquids, and the first groove communicates with flow channel for liquids, and when braking, the brake fluid flowed in the first groove can take away the partial heat at piston place, plays certain cooling action to piston.
Further, in order to effectively reduce the burr of brake calipers surrounding, prevent the stress of brake calipers surrounding from concentrating, the surrounding of brake calipers has the circular arc chamfering preventing stress from concentrating.
Further, conveniently brake slipper was installed with coordinating of piston, and piston and brake slipper fitting surface are also provided with positioning convex.
