Embodiment
Be below specific embodiment of the utility model by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As shown in Figures 1 to 4, originally the brake disc mechanism that is applicable to juvenile automobile is arranged in wheel bearing (not shown), comprise discoid brake disc 10 and the brake calipers 20 that is arranged on brake disc 10 sides, on brake calipers 20, offer the caulking groove 21 with the corresponding setting of brake disc 10, brake disc 10 parts stretch into caulking groove 21 and with caulking groove 21 Spielpassung, brake disc 10 middle parts offer central through bore 11 and central through bore 11 inwalls form around the equally distributed a plurality of installation bases 12 in the center of circle along center of circle direction horizontal-extending, brake disc 10 middle parts are provided with the axle sleeve 30 being all connected with each installation base 12, axle sleeve 30 is set on wheel bearing, brake disc 10 can circumferentially rotate and can be along wheel bearing axial slip around wheel bearing, brake disc 10 has on working surface 13 and working surface 13 and is evenly distributed with a plurality of arc-shaped through-holes 14 around central through bore 11, brake calipers 20 consists of the first caliper 22 and second caliper 23 with oil circuit (not shown), caulking groove 21 is fastened and is formed by the first caliper 22 and the second caliper 23, the first caliper 22 is arranged on the side near working surface 13, the second caliper 23 is arranged on the side away from working surface 13, caulking groove 21 is embedded is provided with the work friction plate 24 with brake disc 10 Spielpassung, work friction plate 24 is arranged on the second caliper 23 by piston (not shown), piston is connected with the oil circuit of the second caliper 23, the second caliper 23 can compress or take-off the brake dish 10 by oil circuit control work friction plate 24.
Originally be applicable to the brake disc mechanism of juvenile automobile under original state, in the second caliper 23, be provided with oil circuit but this oil circuit does not communicate with the first caliper 22, extraneous brake system is connected with the second caliper 23 by oil pipe, and brake disc 10 coaxially arranges by axle sleeve 30 and the wheel bearing of juvenile automobile.
In the course of the work, brake system is controlled the piston in the second caliper 23 by oil pipe, and then piston driving work friction plate 24 towards first calipers 22 are close, caulking groove 21 openings are shunk gradually, and then work friction plate 24 is clamped in brake disc 10 between work friction plate 24 and the first caliper 22.In above-mentioned braking process, the first caliper 22 positions are motionless, work friction plate 24 promotes brake disc 10 and axially slowly towards the first caliper 22 direction slippages, goes over along wheel bearing, finally make brake disc 10 be clamped between work friction plate 24 and the first caliper 22, and then realize brake disc 10 and become braking from rotation, realize the braking of juvenile automobile.In other words, brake disc 10 itself can circumferentially rotate, in braking process, the first caliper 22 and second caliper 23 of brake calipers 20 are also motionless, but the work friction plate 24 in the second caliper 23 can move and drive brake disc 10, the brake disc 10 that endwisely slips is the most at last clamped and made its braking.
The braking process of juvenile automobile is actually the process of utilizing frictional force to be heat energy by kinetic transformation, structural design in this case is conducive to brake disc 10 heat radiations, thereby can as early as possible heat energy be discharged, and then accelerated the conversion rate of brake disc 10, finally make juvenile automobile lose kinetic energy as early as possible and realize braking, further having improved the drive safety of juvenile automobile.
Work friction plate 24 adopts Embedded mounting type, install in actual use, dismantle, change all more convenient, work friction plate 24 makes brake disc 10 coordinate tightr with the braking between brake calipers 20, increased the braking force of 20 pairs of brake discs 10 of brake calipers, reasonable in design and simple in structure, improved braking effect.In addition, also can on the first caliper 22, set firmly at least one auxiliary friction plate, finally can be so that brake disc 10 be clamped between work friction plate 24 and auxiliary friction plate, and then improve braking effect.
In this case, brake disc mechanism overall construction design is simple and volume is little, and each component compact in design, can be installed on juvenile automobile well, simultaneously also suitablely on various vehicles, applies.In addition, in this case, each arc-shaped through-hole 14 is uniformly distributed setting, can make like this heat distribute uniformly, has avoided the heat of brake disc 10 to concentrate, structural design advantages of simple, perfect heat-dissipating.
As shown in Figure 3, further preferably, the shape of arc-shaped through-hole 14 is involute shape, and the quantity of arc-shaped through-hole 14 is eight, can practical requirement and do not affect the manufacturing of brake disc 10.Arc-shaped through-hole 14 is simple in structure and easy to process, and the frictional heat producing in the time of weakening brake disc 10 working surfaces 13 with 24 friction of work friction plate is imported into, increases thermal diffusivity simultaneously, makes brake disc 10 be difficult for producing butterfly-shaped buckling deformation.In addition, arc-shaped through-hole 14 can also alleviate the weight of brake disc 10 own, reduces production costs, and is conducive to fricative dust discharge between brake disc 10 and work friction plate 24.
Again further preferably, each arc-shaped through-hole 14 is all cut the working surface 13 of brake discs 10 with 30 ° of angles.The shape of arc-shaped through-hole 14 is involute shape and with 30 ° of angles, cuts the working surface 13 of brake discs 10, structural design is simple and easy to process, rotation while utilizing brake disc 10 braking produces air pressure and imports air-flow, increased by the flow of brake disc 10 air, accelerating brake disc 10 inner airs flows, the heat that while having taken away faster and more juvenile automobile braking, brake disc 10 produces, the amount of heat having produced while having guaranteed brake disc 10 braking can be dispersed in air quickly, thereby enhancing radiating effect, strengthened the stability of brake disc 10, avoided brake disc 10 because of excess Temperature, to cause the problems such as temperature distortion, also greatly reduce the inordinate wear of brake disc 10 and work friction plate 24, significantly improved the working life of brake disc 10.
Preferably, on each installation base 12, all offer mounting hole 121, axle sleeve 30 is arranged on brake disc 10 by a plurality of bolts, bolt and mounting hole 121 corresponding setting one by one.Said structure simplicity of design, makes axle sleeve 30 installation and removal all more convenient, makes brake disc 10 working stabilities and fixed.
Further preferably, the quantity of installation base 12 is six, well practical requirement and easy to process.
Preferably, brake disc in this case 10 adopts stupaliths to make, it can bear 1400 ℃ high temperature and indeformable, do not produce crack, do not shake.Ceramic Disc Brakes 10 than the weight reducing of common cast iron brake disk 10 50% left and right; The friction factor of Ceramic Disc Brakes 10, than high 25% left and right of cast iron brake disk 10, has improved retardation efficiency; The surface hardness of Ceramic Disc Brakes 10 is high, so its wearing and tearing when braking are less, and working life is longer, is four times of steel brake disc 10 mean lifetime.
In addition, the brake disc 10 that stupalith is made is difficult for isolating and changes conveniently, uses phenomenons such as there will not be oxide etch for a long time, has also extended the working life of brake disc 10 mechanisms.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
