CN2324052Y - Disc brake - Google Patents

Abstract

The utility model relates to a disc brake which is suitable for a bicycle and a booster cycle. The utility model is characterized in that a brake body which is spanned at a disc position is floated by a bracket and is fixed to a bicycle frame, one friction plate is fixed to a forcipated brake body, and the other friction plate is fixed on a pin board. When braking steel cable causes a cam arm to rotate, and by the interaction of a cam, a steel ball, the forcipated brake body and the pin board; besides a bracket, all components can do axial movement, and the friction plate is tightly pressed on the disc; because of the reaction of the friction plate, a forcipated body which is provided with a fixing friction plate can do the movement of opposite direction, and the disc is clamped from the both sides; thus, the braking effect is realized. The utility model has the advantages that the large braking force is realized, the walking resistance is not increased, the interval is not needed to be regulated, and a wheel can be disassembled without the disassembly of the bracket.

Description

Disk brake

The utility model relates to a kind of bicycle, boosted vehicle parts.

Bicycle, boosted vehicle majority adopt the traditional circle lock and the locks that rise at present, and braking effect is poor, often needs adjusting.

The purpose of this utility model is to provide a kind of to be influenced the excessive nothing of rim deviation, and dependable performance need not to adjust, and the disk brake that braking force is big is to satisfy different levels people's requirement.

For achieving the above object, the technical solution of the utility model is that it is by disk, caliper lock body, friction lining, cam, steel ball, stator, carriage, dowel plate, screw, compositions such as spring, pincerlike lock body is divided into a left side, right side board and base plate, a hole slot is arranged on base plate, in pincerlike lock body inner space, set gradually cam from left to right, stator, dowel plate, carriage, left side friction lining, disk, right friction lining, restriction swivel arm on stator and the carriage is inserted in the hole slot on the pincerlike lock body base plate, the center of disk by screw fixed on waggon axle is sent out, the carriage two ends are fixed with vehicle axles and vehicle frame respectively, right friction lining is fixed on the right side board of pincerlike lock body, left side friction lining is fixed on the dowel plate, the left side board of pincerlike lock body, cam, stator central authorities all have through hole, the cover that the center has through hole stretches in the above through hole, retracing spring is set in the cover, the screw of band pad passes above-mentioned through hole and is connected with dowel plate, a pulling arm is arranged on the cam, respectively there are three domatic grooves that are mutually 120 degree the cam two sides, there is the phase difference of 60 degree right flank domatic groove position than left surface domatic groove position, three the sloping groove innermost positions in cam left side are with respect to the position of three hemispherical groove on the lock body left side board inside face, three the sloping groove innermost positions in cam right side are with respect to three hemispherical groove positions on the stator left-hand face, be placed with steel ball between groove and the sloping groove, pin passes the through hole on the carriage on the dowel plate, the pin left friction lining of conflicting, on the dowel plate on three pin positions and the lock body left side board phase place of three hemispherical groove positions identical.

This disk brake is the steel cable control type, across being fixed on the vehicle frame by carriage at the locational pincerlike lock body of disk, a friction shoe is fixed on the pincerlike lock body right side board, another then is fixed on the dowel plate, when parking brake the pulling steel cable, cam arm is rotated, mutual action by cam, steel ball, pincerlike lock body, dowel plate, other parts except that carriage are all axially moved, and friction lining is pressed on the disk, because its counteraction, the pincerlike body of fixed friction sheet is housed, to move to reversing sense, disk is picked up from both sides, brake.One end of carriage is contained on the axle, and the other end is contained on the vehicle frame, and not unloading carriage just can removing vehicle tyres.

Advantage of the present utility model is mainly, and this disk brake braking force is big, can not increase walking resistance, and this disk brake is in braking procedure, and the gap between automatic compensation left and right sides friction lining and the disk can be because of not adjusting the undue influence braking effect; This disk brake removes disk and needs to assemble by spiral with an axle skin, remainder can all be assembled into one, carriage one end is contained on the vehicle frame, front and back wheel all can be installed, need not the adjusting play and do not unload carriage and just can load and unload wheel, the convenient installation saved man-hour, increase work efficiency, be applicable to car load factory stock production.

Accompanying drawing 1 is the utility model structural representation (analysing and observe).

Accompanying drawing 2 is the utility model embodiment scheme of installations.

Accompanying drawing 3 is component cam structural representations.

Below in conjunction with accompanying drawing, introduce the utility model is installed on a embodiment on the ordinary bicycle.

As shown in Figure 2, with thick about 2 millimeters, the disk 17 of the about 160-180 millimeter of diameter passes through the screw fixed at its middle part on bicycle rear axle skin 18, the disk brake body is to be positioned on the carriage 12 across floating in the form on this disk, and the hook end 19 of carriage is fixed on the bicycle rear axle 20,21 of the other ends of carriage are fixed on the vehicle frame 22, brake in the both sides that the friction shoe that mainly with asbestos is woof are clipped in disk.Pincerlike lock body 9 Right Inboards are being screwed right friction lining 15, cam 3, stator 10, dowel plate 11 are then being assembled in inboard, a pincerlike lock body left side, 13 of the friction linings in a left side are fixed on the dowel plate 11,12 on carriage floats on pincerlike lock body 9 and the dowel plate 11, overlapping 8 is connected with dowel plate 11, and makes side compression in a dowel plate and the lock body left side all the time by action of the spring by spring 7, screw 6, pad 6.When the parking brake grip conducts to cam 3 by copper wire 23, and when making it to rotate to an angle, domatic groove 24 on the cam two sides is by steel ball 4, make the stator 10 that pastes mutually with it, the pincerlike lock body on the left side moves vertically to cam 3 both sides, stator 10, then promote pin 11, left side friction lining 13 moves right and presses to disk 17, when producing certain pressure, when pressure is greater than spring force in other words, then pincerlike lock body 9 is moved to the left simultaneously, also press to disk 17 left with the right friction lining 15 that lock body 9 right sides are fastening, that is to say that working as the parking brake grip conducts to cam by steel wire, during the cam rotation certain angle, friction lining 14,15 clamp to disk, parking brake is big more the power of using, then gripping power is just big more, reach the purpose of braking, be compressed simultaneously, when disappearing from the parking brake grip at braking procedure medi-spring 7, spring reset, make lock body 9, cam 3, stator 10, dowel plate 11 is adjacent to, and makes the A friction lining of fixing with dowel plate 11 13, and the B friction lining of fixing with lock body 9 15 separates on the disk both sides in the same way, keep certain interval, finish braking and separation process.
