Abstract
System of Driving Sleeve and Coaster Brake Hub Roller Guide Ring Conjunction with Back-Pedalling Brake, consisting of coaster brake hub (6) shell containing co-axial and rotary shaft on one end of which is placed a lever cone with lever, co-axial brake cone (10) and a brake drum (7), while the other end bears co-axial and rotating driving sleeve (1) with rollers, on one end of which is co-axially placed and fixed a roller guide ring (2) and a sprocket (9) on the other, where the driving sleeve (1) containing roller guide ring (2) is interconnected with roller guide ring by means of a shrink link (4).
Description
Technical field
The technical program is a kind of drive shaft sleeve that combines with back pedal brake and falls the coupling system of roller guide ring of wheeled brake hub, it is the part of bicycle back pedal brake and the housing of wheeled brake equipment of forming, and comprise and on an end of this S. A., be provided with the control lever cone of control lever, coaxial brake cone and brake wheel by coaxial S. A..On its other end, be provided with the coaxial rotating drive shafts cover that has roller, this drive shaft sleeve at one end carries the rotary steering ring, and at other end bearing sprocket.
Background technology
In bicycle, bowden wire wheel rim drg or back pedal brake have been used; The manufactured person of the latter is called " torpedo ", and only can directly produce brake action by counter just stepping on trailing wheel, but the braking force of generation effect accumulates in falling on the wheeled brake hub of trailing wheel that drg wherein is set.Known back pedal brake comprises drive shaft sleeve, drive balls, roller guide ring, brake cone, steel brake wheel, control lever cone and control lever at present, and all above-mentioned parts all are arranged on one coaxially, and are inserted in as coaxial turning unit in the housing of rear wheel hub.A disadvantage in actual manufacturing is that the neck of drive shaft sleeve is provided with the groove that is used for relief spring, make be equipped with back pedal brake to fall the material cost of wheeled brake hub higher and install quite complicated.
Summary of the invention
This paper is saving in material cost and simplify assembly working when foot-operated brake is installed for the drive shaft sleeve that combines with back pedal brake and the target in conjunction with the engineering proposal of direct bearing construction in a systematic way view of wheeled brake hub roller guide ring of falling.
By the designed drive shaft sleeve that combines with back pedal brake with fall wheeled brake hub roller guide ring system, realize this effect and eliminated the mentioned defective in front, this system comprises and comprises the wheeled brake hub housing of falling of coaxial S. A., one end of this S. A. is provided with the control lever cone that has control lever, coaxial brake cone and brake wheel, the other end then is born with the coaxial rotating drive shafts cover of roller, coaxial setting and be fixed with the roller guide ring then be provided with and be fixed with sprocket wheel on the other end on the end of this drive shaft sleeve.The core part is the principle of technical scheme, and according to this principle, the drive shaft sleeve that comprises the roller guide ring is by means of shrink link (shrink link) and the interconnection of roller guide ring.
The major advantage of the component coupling system of being advised is, because the roller of shrink link has partly been taken over the function of neck, so cut down material cost when making drive shaft sleeve.Other significant advantage is that shrink link also makes the installation of component carry out to automation.
Description of drawings
Accompanying drawing brings the more information of the designed technical scheme of relevant this paper.Fig. 1 illustrates the sectional side elevation that falls wheeled brake hub that has back pedal brake; Fig. 2 is the conceptual scheme of drive shaft sleeve that is provided with the neck groove of the spring coil that is used to be used for to keep the roller guide ring; And Fig. 3 illustrate be equipped be pressed in conjunction with in the shrink link the conceptual scheme of drive socket of roller guide ring.
The specific embodiment
Shown in Fig. 1 and Fig. 2 wherein with the fixing primitive form that falls wheeled brake hub that back pedal brake is housed of roller guide ring of present known way.This form of wheeled brake hub of falling that has back pedal brake comprises and holds the wheeled brake hub 6 of falling of coaxial S. A. that this S. A. is provided with arm cone 10 and brake control lever 11, brake actuator 8 and steel brake wheel 7.At the other end of this S. A., be provided with coaxial drive shaft sleeve 1 and steel roller 3.
Drive shaft sleeve is provided with the roller guide ring 2 and the sprocket wheel 9 of rotation at opposition side.The details of the prior art fixed form of the roller guide ring 2 that is provided with the neck groove that is used for drive shaft sleeve spring coil 5 shown in Figure 2.
The fixedly new departure of roller guide ring 2 that on drive shaft sleeve 1, rotates shown in Figure 3.Drive shaft sleeve 1 in this form is straight, is not provided for the neck of the groove of drive shaft sleeve shrink link 5.At the chamber of the drive shaft sleeve 1 that is used for placing steel roller 3, put roller guide ring 2, this roller guide ring 2 is centered at drive shaft sleeve 1 by means of shrink link 4.Meanwhile, drive shaft sleeve 1 is by means of shrink link 4 and 2 interconnection of roller guide ring.
As shown in Figure 3, the bottom of shrink link 4 has the laterally recessed portion (cross cut) of cutting, to guarantee the passage of hub axis after extruding 4A.
The work as described below of the wheeled brake hub of falling of back pedal brake is housed: when stepping on forward, power is delivered to drive shaft sleeve 1 by sprocket wheel 9; The steel roller 3 of drive shaft sleeve 1 is shifted onto on the curve of drive shaft sleeve 1 realizing bigger diameter, thereby contacted with the inside face of the hub shell 6 of idle running.By the cooperation of such generation, the hub shell 6 of idle running is with the circumferential speed displacement identical with drive shaft sleeve 1.When counter stepping on (braking), moved minimum diameter by the steel roller 3 of the drive shaft sleeve 1 of roller guide ring 2 braking until curve, and make 2 displacements of roller guide ring with the fwd curve, roller guide ring 2 is pressed in the steel brake wheel 7, and steel brake wheel 7 just begins to expand till the internal diameter of the hub shell 6 that arrives idle running.After obtaining the antagonistic force that brake action produces, stop steel brake wheel 7 and prevent its slippage by combining with arm cone 10 that two protuberances that utilize wherein cooperate.At opposition side, maintain arm cone 10 by the wheeled brake hub control lever 11 that falls on the vehicle frame that is fixed on bicycle by yoke.
Industrial applicability
The driving sleeve of being combined with back pedal brake and fall wheeled braking wheel hub roller guide ring system and particularly can Be used for bicycle.
Claims (1)
1. the drive shaft sleeve that combines with back pedal brake and fall wheeled brake hub roller guide ring system, this system comprises and holds the wheeled brake hub of falling of coaxial S. A.
