Abstract
The utility model relates to a transmission device for a rickshaw, and has a critical point that a vertical stay bar is fixedly arranged in a centre shaft position in a bicycle frame and is provided with an upper and a lower tension wheels with a left and a right parts on the same shaft, wherein, a connecting shaft of the upper tension wheel is fixedly provided with a transmission chain wheel which is linked with a ratchet assembly of a rear wheel through a transmission chain; a driving chain connected with a crank is respectively arranged between the upper and the lower tension wheels, the other end of the crank is connected with pedals fixed on the connecting rod, and a rear end of the connecting rod is supported on a stay frame at a rear part of the bicycle frame. The transmission device with the structure enables circular motion in stepping the bicycle with two feet to be changed into linear motion from top to bottom, and the range of generated radial force is reduced. Therefore, the rickshaw can run more quickly with less labor.
Description
The utility model relates to a kind of novel transmission device for rickshaw.
Travelling of ordinary bicycle or three-wheel vehicle is that both feet by the people move in a circle to scrunch and realize, and every pin only has the half cycle powered vehicle of exerting oneself downwards.When the close last lower dead point of pedal (the pedal position when the power thrusts line of pin passes through the axis axle center), it is diametral load greatly that the power of pedaling of pin has, seldom acting.And when reaching lower dead point, the power of pedaling of pin all is diametral load, and running then will lean on inertia could pass through last lower dead point continuously, or changes the position of going up lower dead point by the force direction of pedaling of adjusting the people.Therefore a part of physical efficiency of people is wasted.In addition, it is long that the circular movement that both feet are pedaled ordinary bicycle or three-wheel vehicle is pedaled route up and down than straight line, and the action more complicated, so both legs are tired easily.
The purpose of this utility model provides and a kind ofly can make that double-legged alternatively up and down is pedaled, and the novel transmission device for rickshaw in labour-saving more.
The utility model is achieved in that the axis position in the rickshaw vehicle frame is fixed with vertical strut, upper and lower two pairs of tension wheels that the left and right sides is coaxial are housed on strut, wherein also be fixed with driving chain wheel on the connecting shaft of upper tension wheel, this driving chain wheel links by the ratchet assembly of driving chain with rear wheel.The chain drive-belt of the crank of ining succession respectively is housed between upper and lower two pairs of tension wheels, and the other end of crank then is connected with pedal, and pedal is fixed on the connecting rod, and the rear end of connecting rod is bearing on the support at vehicle frame rear portion.Like this, when pedaling pedal downwards, crank is just torn chain drive-belt downwards, make the tension wheel rotation, and the drive driving chain wheel coaxial with upper tension wheel, this driving chain wheel then by driving chain with transmission of power to the ratchet assembly coaxial with rear wheel, and then drive whole vehicle and move ahead.The driving device of Gou Chenging makes both feet circular movement to pedal become straight-line motion up and down like this, and has dwindled the scope that diametral load produces greatly.Thereby use bicycle of the present utility model or three-wheel vehicle to ride with more laborsaving and quick.
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is the birds-eye view of Fig. 1.
Fig. 3 removes the left view of driving device behind the vehicle frame wheel for Fig. 1.
In conjunction with Fig. 1, Fig. 2, Fig. 3, be fixed with vertical strut 10 at the axis position of vehicle frame, the coaxial idler sprocket 1 and 6 in upper and lower two pairs of left and right sides is housed on strut 10, wherein also be fixed with driving chain wheel 11 on the connecting shaft of upper idler sprocket, this driving chain wheel 11 links by the ratchet assembly 3 of driving chain 2 with rear wheel, the chain drive-belt 9 of the crank 7 of ining succession respectively is housed between upper and lower two pairs of tension wheels 1 and 6, the other end of crank 7 then is connected with pedal 8, pedal 8 is fixed on the connecting rod 5, and the rear end of connecting rod 5 is bearing on the support 4 at vehicle frame rear portion.For the resistance that reduces friction, the two ends of crank 7 are connected with chain drive-belt 9 and pedal 8 by ball bearing of main shaft respectively.Vertically strut 10 can be regulated length, so that the degree of tightness of controlling and driving chain 9.
Claims (2)
1, a kind of novel transmission device for rickshaw, comprise sprocket wheel, driving chain, ratchet assembly, it is characterized in that: be fixed with vertical strut (10) at the axis position of vehicle frame, on strut (10), be equipped with, idler sprocket (1) and (6) that following two pairs of left and right sides are coaxial, wherein also be fixed with driving chain wheel (11) on the connecting shaft of upper idler sprocket, this driving chain wheel (11) links by the ratchet assembly (3) of driving chain (2) with rear wheel, last, the chain drive-belt (9) of a crank (7) of ining succession respectively is housed between following two pairs of tension wheels (1) and (6), the other end of crank (7) then is connected with pedal (8), pedal (8) is fixed on the connecting rod (5), and the rear end of connecting rod (5) is bearing on the support (4) at vehicle frame rear portion.
2, novel transmission device for rickshaw according to claim 1 is characterized in that the two ends of said crank (7) are connected with chain drive-belt (9) and pedal (8) by ball bearing respectively.
