Description

The caliper disc brake equipment

The utility model belongs to what bicycle brake system field.

Bicycle, automobile are the vehicle important during people live, the continuous development and change of the version of car for these years, and the speed of a motor vehicle also improves constantly.Therefore, also more and more higher, not only aesthetic in appearance to the requirement of vehicle braking performances, and require in-use performance safe and reliable.The normal at present brake equipment that adopts has the lock of rising, band-type brake, pincerlike lock, backpedalling brake or the like.Wherein, backpedalling brake because of handle inconvenience, use less.Pincerlike brake structure is simple, and braking effect is better, uses extensively.But the direct friction rim can make the rim wearing and tearing, and the brake rubber block life-span is short.Rise lock, band-type brake compact conformation, easy to use, use more general, the decline poor performance but these two kinds of locks are paddled, as the circuitous rainy day, braking effect is undesirable, rainy day safety inadequately just by bike.

The purpose of this utility model is the bicycle brake system of a kind of safe and reliable practicality of invention, and control comfort is light and handy, and braking is steadily reliable, good braking effect, and hydrophile can be good, long service life.Small and exquisite, the handsome in appearance novelty of compact conformation.

The technical solution adopted in the utility model is that the caliper disc brake equipment is made up of brake disc, friction lining, caliper assembly and tight rope assembly.Also have the plate assembly in the brake equipment, it is made up of plate [17], U-bolt [16], nut [18], support [12] that left end has U type socket.The caliper assembly is made up of caliper [1], two friction linings [2], friction liner plate [3], the driving disc spacing pressing [4] that has dome, steel ball [5], wherein a slice and the right inwall of caliper [1] in two friction linings is affixed, another sheet is affixed with friction liner plate [3], the opposite side of friction liner plate [3] has uniform webge slot, steel ball [5] is housed in the groove, the left madial wall of the two sides of driving disc spacing pressing [4], caliper [1] all has uniform webge slot, and steel ball [5] is housed in the groove.Cover for seat [7] is fixed in support [12] bottom righthand side, spring [10] and packing ring [9] are housed in the cover for seat [7], and bolt [11] is inserted in the endoporus of friction liner plate [3] and cover for seat [7], and the liner plate that will rub is fixed, the left part of caliper [1] is contained on the cover for seat, and nut [8] is tightened on the bolt [11].Pull back spring [6] is enclosed within on the cover for seat [7], is pressed in caliper [1] in the outside, sees accompanying drawing 2.The tight rope assembly is contained between pincers part [1] lower end flange and the driving disc spacing pressing dome, is accompanying drawing 1.The set screw [21] that wherein has endoporus, be contained in the endoporus of caliper [1] flange, nut [20] is screwed on the set screw, spring [22] one ends are enclosed within on the set screw right-hand member, the other end installs on the small embossment on driving disc spacing pressing [3] dome, and tight rope screw [21] is contained in the internal thread hole on the driving disc spacing pressing dome, and the steel rope on the rim brake [19] is pierced into by the endoporus of set screw [21], pass spring [27], pierce in the hole on the tight rope screw [23], be fixed on the dome of driving disc spacing pressing.

There is screw thread at the two ends of the U-bolt in the plate assembly of brake equipment, and it is inserted in two circular holes of plate [17] left end, and are fixing with nut [18].By packing ring [13], spring washer [14], be fixed tightly in bolt [1 5], the bottom is screwed in together by bolt [26] plate [17] with support [12] top.Be fixed in the bearing pin [25] on the caliper [1], be inserted in the small sircle hole of support [12] lower end.There is tapped bore at brake disc [24] center, and several uniform holes are arranged on the card.

The transmission principle of caliper disc brake equipment: when bicycle hand brake moves, the steel rope [19] that is equivalent in the accompanying drawing 1 is subjected to a pulling force left, this pulling force clockwise rotates driving disc spacing pressing [4], drive steel ball [5], at driving disc spacing pressing, the friction liner plate, caliper rotates in the uniform webge slot on medial surface, because friction liner plate and caliper all are can not rotating of fixing, so work as steel ball under moment loading, when turning to top, promote caliper and the relative side travel of friction liner plate by the webge slot bottom, make friction lining clamp brake disc, reach the purpose of braking.When unclamping lock, steel rope [19] is lax, and caliper and friction plate be return under the effect of pull back spring, and friction lining and brake disc disengage, the take-off the brake dish.

Effect of the present utility model is remarkable, and the main wear-out part of brake equipment is friction lining and brake disc, reasonably selects the material and the technology of these two kinds of parts, can make two kinds of parts very wear-resisting, long service life.These two kinds of parts do not absorb water, so the decline performance of paddling is good, braking effect is good, the rainy day, drag was as safe as a house reliable by bike.Whole brake equipment is installed on the back fork of bicycle beam by the plate assembly, brake disc is screwed on the bicycle rear axle hub just can uses, and easy for installation, compact conformation is handsome in appearance, is applicable to any vehicle.

Accompanying drawing 1 is the External view of pincers dish brake equipment, and accompanying drawing 2 is cutaway views of caliper disc brake equipment.Wherein: 1-caliper, 2-friction lining, the 3-liner plate that rubs, 4-driving disc spacing pressing, 5-steel ball, the 6-pull back spring, 7-cover for seat, 8-nut, 9-packing ring, 10-spring, the 11-bolt, 12-support, 13-packing ring, 14-spring washer, the 15-bolt, 16-U type bolt, 17-plate, 18-nut, the 19-steel rope, 20-nut, 21-set screw, 22-spring, 23-tight rope screw, 24-brake disc, 25-bearing pin, 26-bolt.

Describe an embodiment of the present utility model in detail below in conjunction with accompanying drawing.Earlier brake disc is installed on the hub of bicycle rear axle, when caliper assembly and plate assembly are installed, earlier brake disc is placed between two friction linings, then the U type socket on the plate is inserted on the self-moving vehicle rear axle fastening nut.Take off U-bolt, block the back fork of bicycle beam, be fixed on the back fork of bicycle beam with nut [18] with it.Brake wire on the rim brake is pierced in the tight rope assembly, be fixed on the driving disc spacing pressing with tight rope screw [23].When the cyclist brakes, move rim brake, quite steel rope is subjected to a pulling force left, and this power clockwise rotates driving disc spacing pressing [3], sees accompanying drawing 1 and accompanying drawing 2.Driving disc spacing pressing rotates and to make steel ball [5] be subjected to the twist moment effect, because of friction liner plate [3] and caliper can not rotate, laterally moves right so steel ball promotes friction liner plate friction lining when the bottom of wedge groove turns to top, and the clamping brake disc is finished braking.When rim brake unclamped, steel rope was loose, and driving disc spacing pressing rotates counterclockwise, drives steel ball and forwards the wedge trench bottom to from wedge groove top, under the effect of pull back spring, friction lining and friction liner plate be the side travel return left simultaneously, and friction lining is thrown off, do not contacted with brake disc, the take-off the brake dish can freely travel.
