Abstract

The utility model relates to a bicycle drive mechanism which is used for a bicycle with two wheels and a bicycle with three wheels, and is compose of a plunger, an air cylinder, an exhaust valve, an air motor, a friction wheel, etc. Aerodynamics principle is adopted by the utility model with address, so the purposes of high speed riding, work saving, novel structure and reasonableness are achieved. The utility model plays an important function in promoting urban and rural economic circulation, escaping poverty towards well-off conditions, and booming economy.

Description

Bicycle drive

The utility model relates to a kind of driver train of bicycle, particularly relates to the driver train of a kind of two-wheeled and tricycle.

At present, the driver train of Regular Bicycle is made up of pedal, crank, chain, sprocket wheel or Eight characters gear mostly.Chinese patent (87103306), (88203311), (89207295.4) disclose a kind of hydraulic-driven bicycle, and its purpose is laborsaving, quick.Structure comprises parts such as oil pump, transport pipe, valve, oil motor.The shortcoming that exists is: 1, can not reach at a high speed and purpose efficiently; 2, accuracy of manufacture height, the cost height; 3, complex structure, repairing difficulty.In recent years, Wuxi Bicycle Factory produces a kind of morpet, and it is with the engine petrol tyre rotation that rubs, and reaches province's merit and fast speed purpose.But there is following shortcoming: 1, manufacturing cost, use cost height; 2, precision height is repaired difficulty, is not good at if repair, and can cause leakage of oil, brings many inconveniences to the user.

At the shortcoming of above existence, the purpose of this utility model is the air pressure driver train that a kind of bicycle will be provided.It can be efficiently, economize merit, at a high speed.

The purpose of this utility model can reach by following measure: two inflators are installed in the bicycle middle shaft both sides, have piston to link to each other with piston rod in the inflator, the other end of piston rod joins with hinge form and stretcher.When stepping stretcher with manpower, piston moves back and forth in inflator, and the gas of compression is opened blow off valve, the pipeline of flowing through.Gas shock gas motor wheel rotation is so the friction wheel coaxial with impeller begins to rotate.Because friction force, friction wheel drives the bicycle rear tire and rotates.Bicycle burns the wind.

The utility model, is installed two inflators and a gas motor and just can be realized in former bicycle middle shaft both sides because of a need, thus simple in structure, low cost of manufacture; Simultaneously, ratio of precision hydraulic pressure and engine petrol require low, assembling, repair convenient; In addition, because drive torque is bigger 8 times than former bicycle, net effciency is by 10 original---20% is increased to 80---90%, so with same manpower, speed can be accelerated 3 times.

The drawing of the utility model accompanying drawing is described as follows:

Fig. 1 is the utility model partial elevation view.

Fig. 2 is the utility model A---the A section-drawing.

Fig. 3 is the utility model B---the B section-drawing.

The utility model will be described in further detail in conjunction with the accompanying drawings:

Fig. 1,2 and Fig. 3 in, two inflators (3) symmetries be fixed on cycle frame axis both sides.Fixed form is: on inflator (3), be welded with connecting panel (26), and fastening with screw (14) and vehicle frame axis connecting panel.Vehicle frame axis connecting panel is again a gas motor drive shaft bearing (5) simultaneously.Friction wheel (7) contacts with certain pressure with bicycle rear tire (1), regulates with spring (38).

Among Fig. 1, Fig. 2, be fixed with friction wheel (7), impeller (6) on the axle (40).And adjustment circle (10) and (11) of adjusting the impeller axial location are arranged.Antifriction-bearing box (8) is equipped with at the two ends of axle, and antifriction-bearing box (8) is contained in the bearing seat (5).Bearing seat (5) mills the shape that bearing is moved in the horizontal direction.Compress antifriction-bearing box (8) with spring (38) and arc plate (39), guarantee friction wheel (7) and tire contact pressure.Antifriction-bearing box (8) seals with bearing cap shim (4) and (13).Bearing cover screw (9) is fixing.Adjusting circle (10) is fixed on the axle with nail silk (14).Impeller (6) with apply mechanically key (15) be connected the axle (40) on.And surrounded by circle (12).

Among Fig. 3, stretcher (20) is hinged with pin (21) and piston rod (18), and the form that pin (21) is taken off with the Kazakhstan is hinged with pin (37) and bar thick stick (36), and there is spring cotter (19) the pin end.The middle part of bar thick stick (36) and cramp bar are hinged with pin (35) and cramp bar (22) with the form that the Kazakhstan is taken off again.Cramp bar (22) is welded in the middle of the axis.The other end of piston rod (18) is equipped with guide collar (15), oil-resistant rubber ring (25), and collar (16) constitutes piston.The lower end of each inflator (3) is equipped with blow off valve, and valve joint chair (27) is welded on the inflator bottom, and valve seat (28) is used for adjusting the pressure of spring (34) to valve block (29), and tight loop (33) can prevent that valve seat (28) is loosening.Tracheae (31) one ends are connected with adaptor union (32), and the other end is connected with gas motor wind joint (30).

When alternately stepping on stretcher (20) with pin, piston (forming by 15,16,25) just moves back and forth in inflator (3), and the gas of compression is discharged from blow off valve, enters the gas motor by tracheae (31), and air-flow promotes impeller (6) and rotates.Simultaneously, friction wheel (7) also begins to rotate, and utilizes friction force to drive bike tyre and rotates.Bicycle begins rapidly to run.
