Abstract
The utility model provides a lever power-saving transmission device which comprises a lever, a large wheel, a small wheel, a large wheel shaft, a small wheel shaft, foot pedals, and a chain wheel or a gear, wherein, the large wheel and the small wheel are respectively provided with an eccentric shaft, the levers are connected with the eccentric shafts through connecting rods, the lever fulcrums are supported by a support frame, the small wheel shaft sleeve is fixed to the support frame, the small wheel is connected with the chain wheel through a transmission chain or the gear, and the foot pedals are arranged on the eccentric shaft of the large wheel. The utility model has the advantages of simple structure, convenient manufacture and installation. The lever power-saving transmission device can uses chain transmission or gear transmission. The lever power-saving transmission device can be pedaled by human power, and the lever power-saving transmission device can be driven by a motor. The labour saving can reach more than 2/3 by the lever power-saving transmission device. The lever power-saving transmission device can reduce fatigue and increase speed.
Description
The utility model relates to transmission device.
At present, the manpower drive unit that occurs on the market mostly is the direct transmission of chain as pedicab etc., has both required great effort, and speed does not increase yet.
The purpose of this utility model is to provide a kind of can use chain transmission, available again gear transmission, the lever force-saving transmission device that has laborsaving advantage simultaneously.
The utility model utilizes the lever force-saving principle to realize.
The utility model comprises lever, big steamboat, big or small wheel shaft, foot-operated and sprocket wheel or gear.On the big steamboat eccentric shaft is installed, is connected with link rod between lever and the eccentric shaft, supporting frame support lever fulcrum, little axle sleeve is fixed on the supporting frame, is connected with drive chain or gear between steamboat and the sprocket wheel, rides to be installed on the bull wheel eccentric shaft.Pedal and ride, eccentric shaft drives link rod and pumps, and along with the motion of link rod, lever is done the to-and-fro motion of fan type, drives the link motion that is positioned on the steamboat, thereby steamboat is rotated.If sprocket wheel or gear are installed on the rickshaw drive sprocket axle, because the to-and-fro motion of lever is transformed into the rotation of gear, rickshaw is moved, reach the labour-saving purpose simultaneously.
The utility model can also be provided with arrangements for speed regulation, motor.
The utility model is simple in structure, and fabrication and installation are convenient.It can use chain transmission, available again gear transmission; Can pedal by manpower, useable electric moter is used as power again.Use the utility model can be laborsaving more than 2/3, reduces fatigue, can also pick up speed.
The utility model will be further described below in conjunction with accompanying drawing.
Accompanying drawing 1. the utility model structural representations.Wherein, 1-is foot-operated, 2-eccentric shaft, 3-bearing, 4-bull wheel, 5-wheel shaft, 6-link rod, 7-lever, 8-balance pivot bearing, 9-supporting frame, the little axle sleeve of 10-, 11-steamboat, 12-chain, 13-sprocket wheel, 14-clutch, 15-driving wheel axletree.For the ease of changing the speed of a motor vehicle, the diameter of two steamboats 11 can be different.Between eccentric shaft 2 and link rod 6 bearing 3 is installed, balance pivot bearing 8 is equipped with at supporting frame 9 upper lever fulcrum places, plays light rotary action.
Accompanying drawing 2. supporting frame schematic representation.
Accompanying drawing 3. the utility model are used for rickshaw structural representation (figure b is the plan view of figure a).Wherein, 16-manpower wheel, 17-steering wheel, 18-steering bar, 19-rider seat, 20-vehicle frame, 21-rickshaw wheel shaft.Big axle sleeve, supporting frame are separately fixed on the vehicle frame.Balance pivot is higher than the vehicle frame plane.Upper plate can be freighted on the vehicle frame upper berth, and laying the seat can be manned.
The utility model also can be used for other system.As: can drive other machine rotate by conversion rate.
