Bidirectional different speed ratio driving device with bidirectional manpower input

A bidirectional different speed ratio driving device with bidirectional manpower input of the present invention discloses that the output end of a particular bidirectional manpower input device capable of receiving bidirectional rotating input is transmitted to the input end of the bidirectional different speed ratio speed change device, and it is through the output end of the bidirectional different speed ratio speed change device to operate the bidirectional different speed ratio output for driving the loading wheel train, wherein the user can freely decide the driving input direction to allow the bidirectional different speed ratio speed change device to provide the different rotating directional output at different speed change ratio while in different driving input direction;

• The bidirectional different speed ratio driving device with bidirectional manpower input is through the manpower of both or one of the hand or foot to drive the bidirectional manpower input device(101) for rotating clockwise or counter-clockwise, wherein the rotating power output from the output end of bidirectional manpower input device(101) is transmitted to the input end of the bidirectional different speed ratio speed change device(102) directly or via a transmission device(104) for providing the bidirectional different speed ratio rotating power to drive the loading wheel train(103), wherein:
• The bidirectional manpower input device(101):
• It is constituted by the input mechanism capable of receiving the bidirectional positive or reverse rotating input or reciprocation driven by both or one of the hand or foot of human limbs, wherein its constitution comprises the pedals, crankshafts and the bidirectional rotating transmission wheel train, or comprises the handles, shafts, and the bidirectional rotating transmission wheel train, or comprises the conventional manpower driven bidirectional rotating mechanism;
• The input powers of the first driving rotating direction and second driving rotating direction are from both or one of the hand or foot of the manpower for driving the input end of the bidirectional manpower input device(101);
• The first driving rotating direction and second driving rotating direction are contrary to each other;
• The bidirectional different speed ratio speed change device(102):
• The bidirectional different speed ratio speed change device(102) receives the different directional rotating power from the bidirectional manpower input device(101) directly or via a transmission device(104) while provides the bidirectional different speed ratio power output;
• the bidirectional different speed ratio speed change device(102) is constituted by the internal transmission components of the following:
• 1) gear train;
• or 2) friction wheel train;
• or 3) chain and sprocket train;
• or 4) belt and pulley train;
• or 5) transmission crankshaft and wheel train;
• or 6) fluid transmission device;
• or 7) electromagnetic transmission device;
• or it is constituted by one or more than one of above said transmission components;
• when the bidirectional different speed ratio speed change device(102) is driven by the different rotating directional inputs of the first driving rotating direction and second driving rotating direction, the relative directional relationship at the bidirectional output end corresponding to the reversely different input direction at the input end can be the same or different, and the speed ratios between the output directions corresponding to different input directions are different;
• The loading wheel train(103):
• It is a wheel-type load driven by the output end of the bidirectional different speed ratio speed change device(102) directly or via the wheel load of a transmission device(104);
• The present invention is especially applying as an upright bidirectional pedaling bicycle or as an upright bidirectional pedaling device for lower limbs bidirectional pedaling in order to widen the use of muscles and change the muscle strength and density, and obtain the following advantages:
• (1) reducing injuries caused by overuse of partial muscles and joints;
• (2) working the muscles and joints seldom being used or trained;
• Above advantages can be applied at various bidirectional manpower driving using different muscle groups;
• especially when apply bidirectional pedaling driving at upright bicycles or upright pedaling exercise devices, the difference of the muscle groups using for bidirectional pedaling is bigger, that makes the said advantages and their effects more obvious.
