Description
Technical field
This utility model relates to spot-type disc brake, is specially a kind of disc brake with fixed caliper with cooling vent.
Background technology
Brake is in order to produce to hinder the parts of the power of vehicle movement or movement tendency in brakes, automotive brake is except various retarding devices, it it is nearly all the friction brake of the friction generation braking moment utilizing retaining element with rotating element manipulation surface, at present, the friction brake that all kinds of automobiles are widely used is divided into drum brake and the big class of disk brake two according to the difference rotating element.
Spot-type disc brake is a kind of conventional disk 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, 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, have influence on service life and the performance of brake.
Utility model content
This utility model is intended to provide the abrasion of a kind of effective minimizing brake block, improves the disc brake with fixed caliper with cooling vent of brake life and performance.
The disc brake with fixed caliper with cooling vent in this programme, including caliper and braking dish, braking dish is fixed on outside wheel, caliper is across being connected in braking dish both sides and with outside vehicle bridge, caliper offers oil-in and flow channel for liquids, oil-in and flow channel for liquids communicate, the flow channel for liquids of braking dish both sides is symmetrically arranged with piston, piston is provided with brake block towards braking dish side, piston and brake block mating surface are further opened with some louvres, position vertical with louvre on piston is further opened with through hole, through hole communicates with louvre, piston place is additionally provided with extension spring, extension spring one end is connected with piston, the extension spring other end is connected with caliper.
The operation principle of this programme is: when needs are braked, brake fluid enters flow channel for liquids through oil-in, it is positioned at the piston on the flow channel for liquids of braking dish both sides to move to direction, braking dish place under the effect of brake fluid simultaneously, until the brake block of both sides and the laminating of braking dish, braking dish realizes braking under the effect of both sides brake block frictional force, substantial amounts of heat will be produced when brake block is braked under frictional force effect, the heat that now brake block produces is transferred on the piston that is connected with brake block, if the louvre offered on the face that brake block coordinates with piston, the heat being delivered to piston is directly contacted with air by louvre, and in time the heat in piston is distributed by the through hole communicated with louvre.
The effect of this programme is: by offering louvre at brake block and piston mating surface, and offer through hole at louvre place, increase the contact area of piston and air, make brake block be delivered to the heat on piston in braking procedure and can be discharged in air by louvre and through hole timely and effectively, thus it is too high to avoid brake block temperature in braking procedure, it is effectively reduced the abrasion of brake block, improves life-span and the performance of brake.
Further, piston is further opened with lightening hole, louvre communicates with lightening hole, lightening hole on piston can alleviate the weight of piston on the one hand, improve the piston response speed when braking, on the other hand, the louvre on piston communicates with lightening hole can increase the contact area of piston and air further, strengthens the heat-sinking capability of piston.
Further, in order to increase the contact area of caliper and air, improving the heat-sinking capability of caliper, simultaneously in order to the production and processing making caliper is convenient, caliper is provided with some radiating ribs with tapering.
Further, piston is additionally provided with for piston is carried out spacing projection, the through hole described projection of traverse, after braking completes, piston resets under the effect of extension spring, when the projection on piston offsets with caliper, the position of piston is limited, and brake block and braking dish can be made to be maintained at the good distance of braking ability by projection.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment.
Detailed description of the invention
Below by detailed description of the invention, this utility model is described in further detail:
Accompanying drawing labelling in Figure of description includes: wheel 1, braking dish 2, vehicle bridge 3, caliper 4, oil-in 5, flow channel for liquids 6, piston 7, brake block 8, lightening hole 9, extension spring 10, louvre 11, through hole 12.
Embodiment is substantially as shown in Figure 1: have the disc brake with fixed caliper of cooling vent, including caliper 4, in caliper 4 vehicle bridge 3 mounted externally, caliper 4 is across in braking dish 2 both sides, rotate on the wheel 1 that braking dish 2 is mounted externally and together with wheel 1, oil-in 5 is offered in the left side of caliper 4, caliper 4 is further opened with flow channel for liquids 6, the right side of oil-in 5 communicates with flow channel for liquids 6, flow channel for liquids 6 is also across the both sides at braking dish 2, left side at caliper 4, the outline on upside and right side is further opened with some radiating ribs, the tapering that radiating ribs is certain in order to convenient processing and manufacture has, wherein radiating ribs connects with caliper 4 the big end that end is tapering.
nullOn the flow channel for liquids 6 of braking dish 2 both sides, left and right is arranged with piston 7，Piston 7 is additionally provided with brake block 8 towards braking dish 2 side，During braking，Brake block 8 clamps braking dish 2 from both sides，It is respectively equipped with projection in the upper side and lower side of piston 7，This projection is in that caliper 4 can be used for limiting the position of piston 7 when offseting，Medium position at piston 7 is further opened with lightening hole 9，The cross section of lightening hole 9 is rectangular-shaped，Piston 7 between lightening hole 9 and brake block 8 offers some louvres 11，The present embodiment is provided with on piston 7 four louvres 11 of the same size from top to bottom，A through hole 12 from top to bottom it is additionally provided with on the right side of piston 7，This through hole 12 all communicates with four louvres 11，Louvre 11 adds the contact area of piston 7 and air，Thus adding the heat-sinking capability of piston 7.
Extension spring 10 it is additionally provided with between caliper 4 and piston 7, extension spring 10 one end is connected with caliper 4, extension spring 10 other end is connected with piston 7, after having braked, piston 7 drives brake block 8 to separate with braking dish 2 under the effect of extension spring 10, projection on brake piston 7 and caliper 4 offset, if the distance between brake block 8 and braking dish 2 is excessive, when being braked, need significantly high hydraulic pressure that brake block 8 and braking dish 2 just can be made to fit, by arranging projection on piston 7, brake block 8 and braking dish 2 can be made to keep suitable distance, this distance does not interfere with the normal operation of braking dish 2 on the one hand, also brake block 8 can be made just to fit with braking dish 2 and be braked under relatively low hydraulic pressure on the other hand.
