Abstract
The utility model discloses a speed variator used on a push-bike, and speed variation can be realized through positive and reverse treading. The utility model is fixed on a centre shaft and is composed of a controllable external jack, an internal gear, a speed variation ring, an external toothed ring and a sprocket gear, wherein, when a push-bike is positively trod, the internal gear acts with the external toothed ring through a planet gear and an internal jack so as to enable the sprocket gear to rotate forward; when the push-bike is reversely trod, the controllable external jack acts with the speed variation ring, the internal gear is reversely rotated, the planetary gear and the external toothed ring are driven to positively rotate to generate a new transmission ratio, and thus, the purpose of speed variation is realized through the positive and reverse treading. The utility model can be combined with an external speed variator to realize a multi-step transmission ratio (such as 30 speed variation); if a user frequently rides the push-bike provided with the utility model, the utility model can have the function of improving the health of the body of the user.
Description
The utility model relates to a kind of bicycle transmission system.
Present bicycle (bicycle, trishaw, foot-operated mini-motorcycle) becomes a quick-mounting and puts, not very good, though have laborsaving, advantage efficiently as outer change-speed box, can not ride by back-pedalling, and from low speed to high speed or from moving a plurality of positions to low speed (is example with 15 speed) at a high speed.Though internal speed changer can still have the speed change gear few with handing over fast Transmission be sealed in the shell, can not ride by back-pedalling, and shortcoming such as cost height.
Task of the present utility model provides a kind of transmission system that positive back-pedalling can produce multistage transmitting ratio that passes through, and to widen the Applicable scope of bicycle, satisfies various bicycles and more bicyclists' needs.
The utility model is to realize like this; The center tap of bicycle tighten intrinsic controlled outside very heavy support, outside controlled, be hinged with outside controlled very heavy on the very heavy support, on axis, be connected with inner gear, inner gear has the speed change ring outward, on the speed change ring, be equipped with several planetary wheels and in very heavy, and have and outer very heavy unidirectional of contacting at the one end, outside the speed change ring, outer tooth ring is arranged, the sprocket wheel that one or more pieces moduluses are identical, the number of teeth does not wait is arranged above the outer tooth ring.Planetary wheel is meshed with inner gear, outer tooth ring, interior very heavyly engage with outer tooth ring.The speed change ring respectively and be provided with flat shelves, little ball and silk shelves between the inner gear, outer tooth ring.Before axially (anticlockwise direction) when pedaling, axis, inner gear forward, inner gear by planetary wheel and in very heavy and outer tooth ring effect, sprocket wheel just rotates forward, and drives bicycle and advance.When back-pedalling (clockwise direction), interior very heavy skidding, unidirectional effect of controlled outer very heavy and speed change ring one end, inner gear counter-rotating also drives planetary wheel and outer tooth ring is just changeing and produces a new transmitting ratio, and drive bicycle by sprocket wheel and the Transmission that is complementary and advance, thereby reach the purpose that realizes speed change by positive back-pedalling.
Owing to adopted the inside and outside speed-changing mechanism of positive back-pedalling in the technique scheme, can be applicable to bicycle widely, trishaw, human powered vehicles such as light-duty transmission car, body-building vehicle, often bicyclist's waist, leg muscle, can obtain counter motion, can improve the blood of human body circulation, regulate nervous centralis, fat-reducing etc.Compare with other transmission systems, have multi-functional, simple in structure, advantages such as cost is low, easy enforcement, extensive market.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is an organigram of the present utility model.
As shown in Figure 1: controlled outer very heavy support (2) is fastened on the center tap (1), controlled outer very heavy (3) are hinged on the controlled outer very heavy support (2), inner gear (5) is connected on the axis (4), several planetary wheels (6) and several interior very heavy (9) are housed on the speed change ring (8), the one end have with controlled outside very heavy unidirectional (11) that contact, planetary wheel (6) respectively with inner gear (5), outer tooth ring (7) is meshed, interior very heavy (9) engage with outer tooth ring (7), sprocket wheel (10) is arranged, speed change ring (8) and inner gear (5) on the outer tooth ring (7), flat shelves are arranged between the outer tooth ring (7), little ball and silk shelves.When footstalk when (anticlockwise direction) rotates forward, skid controlled outer very heavy (3), footstalk drives axis (4) inner gear (5) by very heavy (9) in the planetary wheel (6) and outer tooth ring (7) effect, sprocket wheel (10) is (conter clockwise) rotation forward just, and the drive bicycle advances.When pin back-pedalling (clockwise direction), skid interior very heavy (9), controlled outer very heavy (3) act on unidirectional (11) of speed change ring, inner gear (5) counter-rotating drives planetary wheel (6) and outer tooth ring (7) just changes, and producing a new transmitting ratio, the Transmission by sprocket wheel (10) and coupling drives bicycle and advances.If go up the installation sprocket wheel that a plurality of moduluses are identical, the number of teeth does not wait at sprocket wheel (10), coupling is dialled the chain device again, just can obtain the novel bicycle transmission system that internal speed-changing combines with outer speed change.
Claims (2)
1, a kind of bicycle transmission system, it is characterized in that the controlled outer very heavy support (2) that controlled outer very heavy (3) are housed is fastened on the center tap (1), inner gear (5) is connected on the axis (4), several planetary wheels (6) and several interior very heavy (9) are arranged on the speed change ring (8), and the one end have with controlled outside very heavy unidirectional (11) that contact, planetary wheel (6) is meshed with inner gear (5), outer tooth ring (7) respectively, interior very heavy (9) engage with outer tooth ring, and sprocket wheel (10) is arranged on the outer tooth ring (7).
2, transmission system according to claim 1 is characterized in that on the sprocket wheel (10) sprocket wheel that a plurality of moduluses are identical, the number of teeth does not wait being installed.
