Abstract
The utility model relates to a double-speed double-wheel driving gear for bicycles, which is composed of a centre shaft, pedals, a wheel disc, a chain, a free wheel, a front wheel nave, and a back wheel nave. An NGW planetary differential mechanism is arranged on the right side of the centre shaft, a sun wheel is fixed into the integration with conical gears, an outer tooth ring is fixed into the integration with the wheel disc, and a planetary frame is fixed into the integration with pedals and fixedly connected to the centre shaft. A conical gear free wheel is additionally arranged on the front wheel nave. The conical gears arranged on both ends of a flexible shaft are respectively engaged with the conical gears and the conical gear free wheel. A ratchet pawl shaft used for supporting ratchet pawls is fixed on a bicycle frame. The utility model has the advantages of good driving performance on the road surfaces with ice, snow, and rain, good passing ability on the upslope and the silting road surfaces, no influence of the on and off effect of lady's bicycles, and two speed change function.
Description
The utility model relates to the design and the manufacturing technology field of bicycle driving device.
According to reported in literature: existing at present dual wheel driven bicycle, it is to realize the front and back wheel power distribution at bicycle rear axle, and front wheel hub power relies on the transmission of very long flexible axle (or reel chain).
The purpose of this utility model is, provides a kind of and realizes closely that at front-wheel double-driving force distributes, and bicycle double speed two-wheel drive device that can speed change.
The utility model is achieved in that installs a NGW planetary differential (" in the mechanism design handbook standard is arranged) on the right side of ordinary bicycle (comprising lady's bicycle) axis, this diff is made of pinion carrier, sun wheel, external toothing, satellite gear and compensating-gear shaft.Axis left side structure is constant.Sun wheel in the diff and bicycle umbrella gear are fixed into one; The pinion carrier in the diff and the wheel disc of bicycle are fixed into one, and pinion carrier and bicycle pedal are fixed into one, and are fastenedly connected with axis.Front wheel hub adds a umbrella tooth flywheel (sprocket wheel on the flywheel is changed into bevel gear), the bevel gear at flexible axle two ends respectively with bicycle on bevel gear and umbrella tooth flywheel engagement, the rear-wheel hub structure is constant.Pawl axis is fixed on the vehicle frame, supports ratchet.Whole device can be installed in the bicycle manufacturing process, also can reequip existing bicycle.
The contrast accompanying drawing is specified below.
Accompanying drawing is the utility model structural representation
1-bicycle middle shaft 2-pinion carrier 3-sun wheel 4-external toothing 5-bevel gear 6-satellite gear 7-compensating-gear shaft 8-pedal 9-wheel disc 10-chain 11-flywheel 12-rear-wheel hub 13-bevel gear 14-flexible axle 15-bevel gear 16-umbrella tooth flywheel 17-front wheel hub 18-vehicle frame 19-ratchet 20-pawl axis
With NGW planetary differential integral installation on axis (1) right side.Sun wheel wherein (3) is fixed into one with bevel gear (5), and external toothing (4) is fixed into one with wheel disc (9), and pinion carrier (2) is fixed into one with pedal (8) and is fastenedly connected with axis (1).Front wheel hub (17) adds a bevel gear flywheel (16), and the bevel gear (13,15) at flexible axle (14) two ends meshes with bevel gear (5), umbrella tooth flywheel (16) respectively.Support the pawl axis (20) of ratchet (19) to be fixed on the vehicle frame (18).
Principle of work of the present utility model is: pedal (8) rotates with pinion carrier (2), drives four compensating-gear shafts (7) and planetary wheel (6), and planetary wheel (6) then drives sun wheel (3) and the external toothing (4) that is engaged with, and can rotate differentially.Wheel disc (9) and then external toothing (4) rotates, and drives rear-wheel hub (12) by chain (10), flywheel (11); Bevel gear (5) and then sun wheel rotates, and drives front wheel hub (17) by ingear bevel gear (13), flexible axle (14), intermeshing bevel gear (15) with umbrella tooth flywheel (16), realizes that the bicycle front and rear wheel drives.When ratchet (19) was in as the accompanying drawing position, the bicycle transmitting ratio was normal; When ratchet (19) around pawl axis (20) A to when rotation, with bevel gear (5) engagement, it is fixed.Flexible axle system (13,14,15) also just can not rotate, and front wheel hub (17) is because the effect of umbrella tooth flywheel (16) still can be to front slide.At this moment, the transmitting ratio between wheel disc (9) and axis (1) strengthens because of the effect of NGW planetary differential, thereby has realized that this bicycle double speed speed change rides.
The utility model has the advantages that on ice, snow, rain road surface good travelling and upward slope and muddy road surface are arranged The advantage that trafficability characteristic is good; And having does not affect the effect that lady's bicycle is got on or off the bus at the camber beam place; Possess simultaneously two grades of changes The speed function.
Claims (1)
- Bicycle double speed two-wheel drive device, form by axis, pedal, wheel disc, chain, flywheel, front and back wheel hub, it is characterized in that the NGW planetary differential is contained in the right side of axis (1), sun wheel (3) is fixed into one with bevel gear (5), external toothing (4) is fixed into one with wheel disc (9), pinion carrier (2) is fixed into one with right pedal (8) and is fastenedly connected with axis (1)Front wheel hub (17) adds a bevel gear flywheel (16), and the bevel gear (13,15) at flexible axle (14) two ends meshes with bevel gear (5), umbrella tooth flywheel (16) respectively,Pawl axis (20) is fixed on the vehicle frame (18), supports ratchet (19).
