Abstract
A disk brake device comprises a brake disc and a brake caliper arranged at the edge of the disc. The brake caliper comprises brake shoes. At least one circular curved groove is formed in the friction surface of the brake disk, and the friction surfaces of the brake shoes are circular curved protruding ribs matched with the circular curved grooves. According to the disk brake device, the grooves are formed in the brake disk surface, so that the friction area is increased, and the brake force can be improved without large stepping force, large oil pressure or a brake disk with the large diameter. The circular V-shaped grooves are matched with the circular V-shaped protruding ribs, so that when the circular V-shaped grooves and the circular V-shaped protruding ribs are completely attached (included angles of the grooves and the protruding ribs are identical) and as the average width numerical value of the V-shaped protruding ribs is slightly larger than the average width numerical value of the V-shaped grooves, the top ends of the V-shaped protruding ribs are arc, huge clamping force is generated by the grooves if the V-shaped protruding ribs move forwards slightly, and braking can be performed effectively; the matching situation of circular trapezoid grooves and circular trapezoid protruding ribs are the same with the matching condition of the circular V-shaped grooves and the circular V-shaped protruding ribs.
Description
Technical field
The present invention is mainly used in brake and drive system for vehicle with tow, also can be used for the brake system of other rotatable parts, is exactly specifically a kind of disc brake device being made up of the braking clamp of a brake disk being connected with wheel and disk border.
Background technique
Disk type brake is also in disc brakes sometimes, two kinds of its point common disk type brake and ventilated disc brakes.Ventilated disc brake is in card, to get out many circular vent holes, or on the end face of dish, cuts out ventilation slot or precast the vent hole of rectangle. ventilated disc brake utilizes its cold and hot effect of distinguished and admirable effect better than common disk type brake.The major advantage of disc brakes is can brake rapidly in the time braking at a high speed, the constancy that radiating effect is better than drum brakes Braking efficiency is good, be convenient to the advanced electronic equipment as ABS installed. use slug (dish) and without drum, there is a smooth brake shoe on the both sides of brake disc, the oil pressure coming when general braking pump is sent to a point cylinder, brake shoe is clamped to brake disc, to reach the tight effect of stopping, at present generally for front-wheel, the senior car device four-wheel disc brakes having, its advantage is that effect is sensitive, heat radiation is good, needn't adjust braking gap, maintenance easily.
Disc brakes mechanical type or hydraulic type Mechanic or Hydraulic (Actuated) distinguish according to the mode of braking action, or say with the medium of start brake block clamping disc and divide, and the one, braking string, the one, oil.
Mechanical disc brake, rubs by the brake block in clamp and clamps disc by the pulling force of braking string, produces braking effect.Hydraulic type, taking fluid as medium, draws brake the piston compression fluid that is start the inside, and pressure is from the straight-through clamp of oil pipe, thereby the piston in promotion clamp drives brake block clamping disc.
Disk brake caliper has two kinds, a kind ofly fixes inflexibly, and another kind of clamp are loaded onto after vehicle frame or front fork, but can also be movable, and be generally horizontal sliding.The design of floating type clamp means of fixation " can horizontal sliding ", and the negative effect brought of monolateral start disc brake, closely bound up.But it has its benefit, such as vehicle frame, front fork have tolerance issues, even connects the thickness of the application on group seat, all can affect between disc and brake block precisely, make up, proofread and correct so usually rely on pad (washer/spacer).Some floating type clamp has the disc of correction and parallel, the smooth effect of brake block with regard to lay special stress on, and does not worry tolerance issues.
Monolateral start and bilateral start, braking, be exactly soly singlely present in oil pressure or mechanical disc brake, but mechanical disc brake is monolateral start mostly.Monolateral start, namely only has on one side the piston brake block of can extrapolating to exert pressure, rub in disc, and the brake block of the another side ground of waiting at ease for an exhausted opponent, waits opposite that disc is pushed through, and allows both sides all produce break-in effect.Also thereby occurred two kinds of floating type and fixed caliper.Bilateral start, naturally refers in clamp and has piston facing each other, allows brake block clamp together disc from both sides.At present, the number of pistons of disk brake caliper has 1 (monolateral start), 2 (a pair of), 4 (two pairs), at most to 6 (three pairs), piston number needs not be equal to brake block number, because have plenty of on one side and have two pistons, it is but the microscler brake block of a slice; 2 also not necessarily bilateral clampings of brake block, because may be the monolateral dynamic formula of doing.
The topmost task of disc is accepted torment exactly, pure bitter feelings role.Material mostly is stainless steel, and aluminum alloy disc does in some manufacturer, say that radiating effect is relatively good, and also someone does titanium and carbon.Disc must be arranged in pairs or groups " braking flower-drum ", and general traditional rim brake will be changed to disc brake, only has " whole group " to eliminate and change, or uses special adapter.Perhaps, the compatibility of flower-drum and disc also will be careful.Standard disc has 6 screw fixed holes, has in early days 4 cellular types.Disc brakes does not at present have the automatic evil spirit of drum brakes tightly to act on, and making the brake weight of disk type brake is low compared with drum brakes.Friction area between brake block and the brake disc of disk type brake is little compared with drum brakes, makes the strength of brake also smaller.For improving the shortcoming of above-mentioned disk type brake, therefore need larger stampede power or oil pressure.Thereby must use the larger brake disc of diameter, or improve the oil pressure of brake system, to improve the strength of brake.
Summary of the invention
In order to solve the little problem of friction area between brake block and the brake disc of disk type brake, provide the disc brake device that a kind of friction area is large, a small amount of movement of disk brake caliper can produce large frictional force.
