Abstract
The utility model relates to a gravity assistance system of a bicycle, and belongs to the technical field of traffic tools. The gravity assistance system of the bicycle particularly comprises a bicycle body cant beam, a turning labor-saving lever assembly, a gear rack accelerator assembly and a middle axle drive system assembly, and is characterized in that an A-end of the bicycle body cant beam, the turning labor-saving lever assembly, the gear rack accelerator assembly and the middle axle drive system assembly are sequentially connected through a rotating shaft. During the riding, the gravity of a rider drives the bicycle to move through the turning labor-saving lever assembly, a crankshaft connecting rod, the gear rack accelerator assembly and a chain. The gravity assistance system of the bicycle has the benefits that the purpose of saving labor by 50% is fulfilled by making full use of a labor-saving lever, the elastic potential energy and the gravitational potential energy; and the gravity assistance system of the bicycle is mainly applied to the bicycle, a tricycle, an electric power bicycle and the like.
Description
Affiliated technical field
The utility model relates to a kind of gravity force assisted system of bicycle, belongs to technical field of transportation means.
Background technology
When riding, existing bicycle crank rotation system exist upper top to go to the bottom two places without acting " dead point ", and not laborsaving and efficient is low.For example CCTV's 10 covers " I like invention " column is released many bicycle patents, picture crank type gear ﹠ rack structure, the sitting posture double-driving bicycle driven, all to utilize trick to drive simultaneously to realize that hybrid power drives, this is not laborsaving yet in fact, only can increase bicyclist's burden, reduce traveling comfort and complex structure, cost is high.Effort when variable speed bicycle also exists the speed of a motor vehicle high, when laborsaving, the speed of a motor vehicle is low, and manpower is unlike mechanical force, pedal, can't stand the people frequently, is unable to stand, above example all can not well be followed three main points of design manpower tricycle in a word: 1. safety is attractive in appearance, does not change the orthodox car custom, 2. can eliminate driving acting " dead point ", increase moment output, 3. lowering and work-saving and cost are low, the conversion riding posture, fatigue-relieving, Green Travel, the low-carbon (LC) life, the crowd who makes a cycling tour is increasing.
Summary of the invention
the purpose of this utility model is for overcoming the background technology deficiency, provide a kind of bicyclist's of utilization self gravity to come the gravity force assisted system of morpet, the technical scheme that the technical matters that the utility model solves is taked is: be arranged on the axis drive system assembly on bicycle middle shaft, angle between bent axle wherein and left and right crank is 120 °, and captive joint with mono-directional overrun clutch drive chain wheel disc M is coaxial, its Crankpin and crankshaft-link rod, rotate laborsaving lever assembly, car body cant beam A end order rotating shaft successively connects, rotating laborsaving lever assembly B holds top to be connected with the vehicle seat rotating shaft, its middle part and pull back spring expansion and cotraction regulator, pull back spring, the car body cant beam is fixedly connected sequentially.Annular rack in described rack-and-gear accelerator assembly holds the bottom to captive joint with the laborsaving lever assembly B of rotation, and mesh with miniature gears, miniature gears and mono-directional overrun clutch drive chain wheel disc M coaxial rotation, its rotating shaft is connected with accelerator bracing frame bearing on being arranged on the car body cant beam, and described mono-directional overrun clutch drive chain wheel disc M is connected chain to be connected with mono-directional overrun clutch drive chain wheel disc N with bicycle freewheel.when riding, under people's gravity and double-legged driving effect, the people is capable to the bottom, rotate laborsaving lever assembly and crankshaft-link rod driving crank first half Zhou Xuanzhuan acting by vehicle seat, simultaneously annular rack drag again the miniature gears that is meshed with it and coaxial rotation mono-directional overrun clutch initiatively chain drum M by chain also driving crank before the half cycle acting, the firmly driving of both feet and the rebound performance of pull back spring, gravitation energy is become kinetic energy to be forced again and becomes the bent axle of 120 ° to do second half return rotation with the crank angle, this moment, the idle running of rack-and-gear accelerator assembly was not done work, power returns to again upwards pendulum liter of jack-up bicyclist along former road, the slight heave and set that the people is gone round and begun again, bicyclist's gravity is originally that resistance becomes eternal power-assist power unexpectedly, huge like this potential is excavated out and be at every moment oneself the service, body weight is benefited more greatly larger, final assist both feet firmly by be arranged on axis can only single direction rotation the increasing chain sprocket accelerate to drive Vehicle Driving Cycle, especially when overload or upward slope, this hybrid power is the most powerful, its principle is during just as upper large slope, this hybrid power is the most powerful, when its principle is ridden very laboriously during just as upper large slope, the people tends to buttocks and leaves on the upright pedal of vehicle seat, desperately firmly drive mono-directional overrun clutch drive chain wheel disc N the same, people's self gravity is imposed on drive system is difficult travels.
The beneficial effects of the utility model are: when ride manpower dexterously (1), do not do work in the up and down " dead point " of crank rotation, and being done work by bent axle overcomes counteracting mutually.(2) increased the assisted gravity acting, made the bicyclist can economize 50% power (3) and changed fixing stiff attitude when in the past riding, crooked back, thus make parts of body obtain useful exercise.
