Problems solved by technology

The existing transmission device that converts reciprocating motion into rotary motion is the most commonly used crankshaft type, such as automobiles, sewing machines, etc., all adopt this transmission method. The disadvantages of this method are that the transmission has a dead point and the power loss is large; The cooperation of the crank requires high precision; the third is that if this method is applied to a bicycle, it is difficult to meet the requirements of the bicycle not to be able to pedal when coasting

Embodiment Construction

[0011] In the first embodiment of figure 1 Among them, there is a connecting rod (2) behind the pedal (1), the connecting rod (2) is connected with the chain (3), and the other end of the chain (3) is fixed on a tooth of the flywheel (4), and the two flywheels (4) fixed on the flywheel sleeve (8), the flywheel sleeve (8) is fixed on the axle (7), the axle (7) is covered with two springs (5), and one end of the spring (5) is fixed on the spring sleeve (6) , and the other end is inserted into a tooth of the flywheel (4). In this way, when the pedal (1) is pressed down, it will drive the connecting rod (2) and the chain (3) to move down, and the chain (3) will drive the flywheel (4) to rotate forward, and the flywheel (4) will drive the wheel shaft (7) to rotate At the same time, the spring (5) is tightened. When the pedal (1) reaches the limit position, under the twisting of the spring (5), the flywheel (4) is idling negatively, and the chain (3) is wound back to the flywheel ...

Abstract

The invention discloses a double connecting bar-double flywheel drive device, which is characterized by the following: the double connecting bar connect separately to catenation chain, flywheel; the flywheel transfers the alternating motion into gyroscopic motion of axletree; the back-moving spring make the flywheel, bicycle chain and connecting bar auto-reset; because of alternate device of double connecting bar, the double flywheel transfers the intermittent alternating motion into axletree or wheel continuous rotary. The invention simplifies the structure, which has firm property and saves the drive power.

Description

[0001] Technical field: the present invention is a mechanical transmission device that effectively converts reciprocating motion into rotary motion. Background technique: [0002] Existing bicycles are driven by rotation, which leads to large body and high seat, thus there are defects such as laborious driving, unsafe riding, inconvenient carrying and storage, etc. The above problems can be solved by using pedal type driving. But to adopt the pedal drive mode, the key is to have a simple, labor-saving and stable transmission device. The existing transmission device that converts reciprocating motion into rotary motion is the most commonly used crankshaft type, such as automobiles, sewing machines, etc., all adopt this transmission method. The disadvantages of this method are that the transmission has a dead point and the power loss is large; The cooperation of the crank requires high precision; the third is that this method is difficult to meet the requirement that the pedal d...
