Abstract
Description
technical field
[0001] The invention relates to a labor-saving bicycle transmission mechanism, in particular to the labor-saving working principle of a labor-saving bicycle and a double ratchet directional rotation joint device. technical background
[0002] At present, all bicycles step on the pedals alternately with the left and right feet to drive the large crankcase to rotate counterclockwise, and transmit the force to the fixed flywheel, axle hub, and spokes on the rear wheel side through the chain or drive shaft to transmit the force to the outer ring of the rear wheel , so that the rear wheel turns counterclockwise to drive the bicycle forward. The length of the pedal connecting rod is generally 160mm, the diameter is 320mm when the feet alternately step on it, the diameter of the 42 teeth of the large chainring is 170mm, the diameter of the 14 teeth of the flywheel is 60mm, and the outer diameter of the 26-inch bicycle wheel is 660mm. The theory assumes that when the...
Examples
Embodiment 1
[0019] Figure 4 It is the planetary gear type labor-saving bicycle transmission mechanism of the embodiment of the present invention: it includes a bicycle 1, an extended pedal connecting rod 3 (a lever with a joint), and a directional rotating joint device 11 is installed at the rear of the left and right levers, and the left and right sides are oriented Double ratchets 4 (or double one-way bearings) are installed in the swivel joint device 11, and the labor-saving bicycle that directly drives the rear wheel 10 to rotate through the transmission mechanism of the left and right planetary gear 7 (or the transmission shaft of the rear wheel hub) completely subverts the bicycle chain transmission. (or shaft drive) transmission mode. It is characterized in that: an extended pedal connecting rod 3 (a lever with joints), a directional rotation joint device 11 is installed in the middle and rear of the left and right levers, and double ratchets 4 (or double single direction bearing...
Embodiment 2
[0021] Figure 5 It is a cross-sectional top view (the left side in the figure) of the speed change shaft type labor-saving bicycle transmission mechanism of the embodiment of the present invention, as Figure 5 Shown, lengthened pedal connecting rod 2 (lever with joint), directional rotation joint device 11 is installed in the rear part of the lever, and double ratchet 3 (or double one-way joint device 11) is all installed in the left and right sides directional rotation joint device Bearing), ratchet 3 (or one-way bearing) outer ring is fixed with a joint-gear (not shown), the diameter is the same as the diameter of the gear 5 fixed on the frame at the center of the rear wheel, and a bridge gear 4 is fixed in the middle of the two identical gears , when the left pedal 1 is forced to move downward, because the central gear 5 and the frame are fixed and do not rotate, the joint-gear (not shown) and the bridge gear 4 rotate counterclockwise around the central gear 5, because th...
