Abstract
The utility model discloses an attached planetary gear speed changing bicycle, which combines a central axle and a back axle into a whole, leaving out a chain, pedals are directly connected with a multi-purpose main axle arranged on a back wheel of the bicycle, the bicycle is driven by the multi-purpose main axle of the back wheel. A bent pole is extended out of a bottom part of a saddle, one end of the bent pole which is near the chest and the belly of a bicyclist is provided with a back cushion. While riding the bicycle, an upper body of the bicyclist can lean against the back cushion, which contributes to more comfortable and easier ride. The multi-purpose main axle of the back wheel of the utility model consists of a main axle and a set of big and small planetary transmission mechanism; the speed of the bicycle is changed by the big and small planetary transmission mechanism.
Description
The utility model relates to a kind of bicycle, refers to a kind of no axis, no chain, attached planetary gear speed-changing bicycle especially.
At present, common bicycle is all assembled by forward and backward wheel, handlebar, vehicle seat, support and axis, and it drives the rear wheel rotation by pedal, the chain that links to each other with axis, thereby makes cycling.This bicycle structure complexity, the manufacture process requirement height; Axis, wheel disc, chain flywheel and the rear axle shelves are easy to wear, friction force is bigger, and be difficult for maintenance.In addition, because this bicycle, the people is pedaled to ride firmly on axis, and when riding, leg and trunk form knuckle, and inconvenience is had an effect, and is tired easily; Especially mountain bike, racing car, human body leans forward more, and the knuckle between leg and trunk is bigger, the effort of riding more, and also the bearing force of arm also increases, and the time is long very tired.
In view of the foregoing, the purpose of this utility model provides a kind of attached planetary gear speed-changing bicycle simple in structure, and this bicycle does not have axis, no chain, non-maintaining.
Another purpose of the present utility model provides a kind of attached planetary gear speed-changing bicycle of using more, and how axis and trailing wheel that this bicycle will have bicycle now unite two into one with main shaft, and this main shaft axle is provided with planetary gear speed-changing, regulating mechanism.
A purpose more of the present utility model provides a kind of attached planetary gear speed-changing bicycle, and this bicycle is provided with and leans forward, the attached vehicle seat, and making riding posture is running posture, more meets the ergonomics principle, and indefatigability is convenient to have an effect, and is easily comfortable.
For achieving the above object, the utility model is taked following design plan: this attached planetary gear speed-changing bicycle, and it is mainly assembled by front vehicle wheel, rear wheel, handlebar, vehicle seat and support; It is characterized in that: the utility model does not have axis, no chain, and pedal directly links to each other with main shaft with bicycle rear is many; How described trailing wheel is made of main shaft, mafor planet gear speed-changing mechanism with main shaft; The mafor planet gear speed-changing mechanism is positioned at a side of rear wheel; Described mafor planet gear speed-changing mechanism is made up of external tooth wheel disc, main brass, gear case and flywheel successively; Be distributed with three double-layer gears in the gear case equally spacedly.
Described trailing wheel is many also can be made of main shaft, small planetary gear speed-changing mechanism, mafor planet gear speed-changing mechanism with main shaft; Large and small epicyclic transmission lays respectively at the and arranged on left and right sides of rear wheel, and links to each other with left and right pedal respectively; Described small planetary gear speed-changing mechanism is made up of internal tooth wheel disc, gearcase and flywheel successively; Be distributed with three miniature gearss in the gearcase equally spacedly; Described mafor planet gear speed-changing mechanism is made up of external tooth wheel disc, main brass, gear case and flywheel successively; Be distributed with three double-layer gears in the gear case equally spacedly.
Stretch out a knee in the bottom of described vehicle seat, the chest belly of an end of knee, close human body is provided with a back cushion.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model appearance structure scheme drawing.
Fig. 2 uses main shaft appearance structure scheme drawing for the utility model trailing wheel more.
Fig. 3 is the utility model small planetary gear speed-changing mechanism package assembly scheme drawing.
Fig. 4 is the utility model mafor planet gear speed-changing mechanism package assembly scheme drawing.
As shown in Figure 1, the utility model attached planetary gear speed-changing bicycle is assembled by front vehicle wheel 1, rear wheel 2, handlebar 3, vehicle seat 4 and support 5.The difference of it and ordinary bicycle is: the utility model does not have axis, no chain, and with the axis of existing bicycle with trailing wheel is many unites two into one with main shaft, pedal directly links to each other with main shaft with bicycle rear is many, directly uses spindle by trailing wheel more, rides.
As shown in Figure 2, how the utility model trailing wheel is made of main shaft 61, small planetary gear speed-changing mechanism 62, mafor planet gear speed-changing mechanism 63 with main shaft 6; Large and small epicyclic transmission 62,63 lays respectively at the and arranged on left and right sides of rear wheel 2, and links to each other with left and right pedal respectively.
As shown in Figure 3, small planetary gear speed-changing mechanism 62 is made up of internal tooth wheel disc 621, gearcase 622 and flywheel 623 successively; Be distributed with three miniature gearss 624 in the gearcase 622 equally spacedly.When riding, pedal drives the inner gear disc spins, and the internal tooth wheel disc drives the flywheel rotation by three miniature gearss again, and flywheel drives the rear wheel rotation again.
As shown in Figure 4, mafor planet gear speed-changing mechanism 63 is made up of external tooth wheel disc 631, main brass 632, gear case 633 and flywheel 634 successively; Be distributed with three double-layer gears 635 in the gear case 633 equally spacedly.When riding, pedal drives the external gear disc spins, and the external tooth wheel disc drives the flywheel rotation by three double-layer gears in the gear case, and flywheel drives the rear wheel rotation again.
The utility model utilizes large and small epicyclic transmission speed governing.When user's forward was ridden, the mafor planet gear speed-changing mechanism drove wheel and moves ahead, and the speed of a motor vehicle is fast.When the user oppositely rode, the small planetary gear speed-changing mechanism drove wheel and moves ahead, and is laborsaving but the speed of a motor vehicle is slow, thereby reaches the purpose of speed governing.
As shown in Figure 1, the utility model stretches out a knee in the bottom of vehicle seat 4, an end of knee, is provided with a back cushion 41 near the chest belly of human body.When riding, the human body first half can lean against on the back cushion 41.It is more comfortable, laborsaving to ride like this, for a long time.
Because the utility model adopts above design plan, so have the following advantages: how the axis and the trailing wheel that 1, will have bicycle now unite two into one with main shaft, make body structure simple, and manufacturing process is more simplified.2, pedal is directly linked to each other with main shaft with trailing wheel is many, when riding, forward lean more meets the anthroposomatology principle.Can firmly kick backward and ride as 100-meter dash, quicken to ride, and laborsaving.3, owing to stretch out a knee in the bottom of vehicle seat, an end of knee, be provided with a back cushion near the chest belly of human body, so when riding, the human body first half can lean against on the back cushion, it is more comfortable, light to ride.4, because how trailing wheel is made of one group of large and small epicyclic transmission with main shaft, people can ride by forward and reverse pedaling, and reach the purpose of speed governing.
The above only is preferred embodiment of the present utility model, and any equivalent transformation based on technical solutions of the utility model all belongs within the utility model protection domain.
