Description

One kind is lain formula pedal three-wheel bicycle

Technical field

Originally practical to be related to a kind of tricycle, especially a kind of reclining type three-wheeled bicycle.

Background technique

Usual bicycle driving is single pedal, is moved in a circle, due to pedal power direction cannot always perpendicular to shaft, Waste power, inefficiency of riding, and be single foot pedaling during having an effect without backrest, pedal power cannot maximum play Come, affects the advance travel speed of car.

Utility model content

The purpose of the utility model is to provide a kind of both feet to scrunch simultaneously, and is linear stroke, makes to pedal power direction always Perpendicular to shaft, it can make to pedal power and obtain maximum performance always in the process of moving, substantially increase the utilization rate for pedaling power, meanwhile, Guide wheel has certain altitude afterwards, and to adapt to organization of human body, sufficiently having an effect conducive to both feet has root.

The technical solution of the utility model

A kind of foot-operated driving bicycle of linear reciprocating, including it is vehicle frame, rear wheels, rear chain, axis group, preceding chain, preceding Wheel group, front jocket wheel draw rail, steering shaft, ride, rear guide wheel, braking system, turning to hand, and described stroke of rail is fixed on vehicle frame, described Foot-operated be mounted on is drawn on rail；The preceding chain is fixed on foot-operated；Described stroke of rail be equipped with two lower guideways, two upper rails and Connection rivet；It is described to ride equipped with limit plate, draw axis, preceding stroke of axis, foot pedal afterwards；The preceding chain around axis group, front jocket wheel, Foot-operated, rear guide wheel forms enclosed linear reciprocation drive system；The rear wheels are existing common coaster brake wheel group, by its inside two A brake block removes.

The utility model has the following beneficial effects:

Rationally, structure is simple for design, because structure is that reclining posture leans against, rides comfortable, not easy to fatigue, stability is high.Energy It enough utmostly plays and using power is pedaled, riding speed is fast.

Specific embodiment

The purpose of this utility model is achieved through the following technical solutions

A kind of foot-operated driving bicycle of linear reciprocating, described stroke of rail 8 are fixed on vehicle frame 1, and described foot-operated 10 are placed in It draws on rail 8, the preceding chain 5 is fixed on foot-operated 10, and described stroke of rail 8 is equipped with two lower guideways, 15, two upper rails 16 and connects Rivet 17 is connect, described foot-operated 10 are equipped with limit plate 18, draw 20, two pieces of axis 19, preceding stroke of axis foot pedals 21 afterwards；Preceding chain 5 is in Axis flywheel 14, front jocket wheel 7 ride 10, rear guide wheel 11 formation enclosed linear reciprocation drive system.

Based on vehicle frame 1, rear wheels 2, axis group 4, front wheels 6, front jocket wheel 7, stroke rail 8, steering shaft 9 are passed through into spiral shell The fasteners such as bolt, nut are connected and fixed on vehicle frame 1, and rear guide wheel 11 is fixed on by fastener and is drawn on rail 8, and bilateral turns to Hand handle 13 is fixed in front wheels 6 by welding manner, and axis flywheel 14 is mounted in axis group, and foot-operated 10 are placed in a stroke rail 8 On lower guideway 15 and upper rail 16 among, the part of braking system 12 be separately mounted to rear wheels 2 and turn to hand handle 13 on, Upper rail 16 is riveted on lower guideway 15 by connection rivet 17；The foot pedal 21 on foot-operated 10 is stepped by both feet when riding to exist It draws and does linear reciprocal stroke along a stroke rail 8 on rail 8, chain 5, axis flywheel 14 do reciprocating rotation around axis group 4 before driving, and drive Axis group 4, rear chain 3 move in a circle, and rear wheels 2 is driven to rotate forward, achieve the purpose that vehicle is driven to move forwards.Rear-wheel Group 2 is to remove existing bicycle coaster brake (backpedalling brake) device of internal two brake blocks, guarantees that foot-operated and chain will not when reversing It slides therewith.Axis flywheel 14 uses existing bicycle freewheel structure, so when both feet drive foot-operated 10 in vehicle operation When paddling or rest on backward any position on stroke rail 8 along a stroke rail 8, it will not influence vehicle and move forwards.
