Embodiment Construction

[0017] 1. The power transmission process of the gear rocker transmission mechanism in sequence:

[0018] exist image 3 Middle: Pedal (1) → Pedal lever (2) → Pedal rotation short connecting rod (3) → Transmission rocker (4) → Large gear rotation pin (5) → Speed ​​up large gear (6) → Reverse Pinion (7) → Forward rotation pinion (8) → Flywheel outer ring flange (10) → One-way live flywheel (11) → Rear wheel hub (12)

[0019] In the process of power transmission, the power drives the pedal rod (2) to rotate through the pedal (1), and the pedal rod (2) is tightly connected with the pedal rotating short connecting rod (3), thus driving the pedal to rotate the short connecting rod (3) Rotate so that the transmission rocker (4) rotates along the pedals to rotate the short connecting rod (3) to rotate in parallel to the center of rotation, thereby driving the two large gears to rotate the pins (5) to rotate the two speed-up large gears in the same direction ( 6) The center rotates t...

Abstract

The invention provides a bicycle gear rocker transmission mechanism. As shown in the figure 3 of the specification, the gear rocker transmission mechanism is composed of a transmission rocker, a speedincreasing large gears, forward and reverse rotation small gears and a one-way movable flywheel; power is sequentially transmitted to a pedal rotation short connecting rod, the transmission rocker, aspeed increasing gear set, the one-way movable flywheel and a rear hub to rotate through a pedal. The designed rotating radius of the pedal rotating short connecting rod is the same as the revolutionradius of a large gear rotating pin, then power is transmitted to the one-way movable flywheel to rotate through a speed increasing large and small gear set, and finally the power is transmitted to the rear hub in threaded connection with the inner ring of the one-way movable flywheel to drive the rear wheel to rotate. Meanwhile, in order to prevent the transmission rocker from misplacing and reversing in the power transmission rotating process, two same-direction rotating speed increasing large gears of which the pin revolution radius is the same as that of a pedal rotating short connectingrod are designed and mounted at the tail part of the transmission rocker and are symmetrically distributed on two sides of the reverse rotation small gear, so that balanced power transmission is achieved, and the phenomenon that the transmission rocker misplaces and reverses possibly in the rotating process is prevented.

Description

technical field [0001] The technical proposal relates to the transmission device in the power transmission process of bicycles, tricycles, electric bicycles and motorcycles, and is especially suitable for the transmission part between the bicycle pedal lever and the transmission part between the output power of the motorcycle engine and the driving wheel. Background technique [0002] At present, the transmission between the bicycle pedal lever and the rear wheel, and the transmission mechanism between the motorcycle engine assembly and the driving wheel are basically roller chain transmission, the transmission efficiency is about 0.9, and the energy consumption utilization rate is not high when riding. If the assembly accuracy between the one-way flywheel and the transmission chain is not adjusted properly, the phenomenon of jamming or chain falling will occur during riding. Moreover, most of the roller chain links are exposed to the air. In rainy and snowy weather for a lo...
