Abstract
The utility model belongs to the technical field of the manufacture of light industry mechanisms. A steering mechanism uses a chain-wheel and chain type steering apparatus; a differential mechanism uses a differential apparatus composed of a rear shaft husk of a bicycle with foot brakes; a foot-pedal mechanism uses a reciprocating foot-pedal apparatus composed of shoe type pedals and hard chains; a speed-changing mechanism uses a fork-shifting speed-changing apparatus. The known quadricycle has complex steering, differential and speed-changing mechanisms and the bicycle is only ridden by one person while the utility model has the advantages of simple structure and easy fabrication and maintenance, and can be ridden by more persons.
Description
The utility model belongs to light industry mechanism and makes the field.
General four-wheeled steering hardware is become with steering gear by the complicated deflector of a cover usually; Box of tricks adopts satellite differential usually; Speed-changing mechanism adopts speed-change gear box.As patent CN2056657U multi-power source four-wheel vehicle.These traditional mechanism complex structures.
It is foot-operated that the pedal position of Regular Bicycle is divided into traditional garden week, also has reciprocating type straight line foot-operated.As patent CN2054779U, its return has a cover fixed pulley group mechanism, and structure is also complicated.And be only limited to single rider.
The purpose of this utility model provides a kind of later-model foot-operated quadricycle.It has light, simple, failure-free steering hardware, box of tricks, footstep mechanism, speed-changing mechanism and can many people riding.
The purpose of this utility model is achieved in that steering hardware adopts sprocket wheel chain-type steering hardware; The differential gear that box of tricks adopts the backshaft skin of pedal brake bike to form; Footstep mechanism adopts footwear formula pedal, the reciprocating type straight line foot pedal apparatus that rigid chain is formed; Speed-changing mechanism adopts the fork type transmission system, and is simple in structure, is easy to make and safeguard.
The concrete structure of utility model is provided by accompanying drawing.Fig. 1. be quadricycle profile lateral plan.Fig. 2 is rear axle assembling unit structure figure.Fig. 3 is the foot pedal apparatus constructional drawing.Fig. 4 is the transmission system constructional drawing.Fig. 5 is the steering hardware constructional drawing.
Below in conjunction with details and the service condition of accompanying drawing detailed description according to the concrete device that the utility model proposes.
This device profile is seen Fig. 1.Its keystone configuration has: footstep mechanism (1), joystick (2), steering hardware (3), hinge-type hinge (4), speed-changing mechanism (5), middle shaft assembly (6), big trochal disc (7), rigid chain (8), can set level seat (9), the back shaft assembly (10).
Stepping stretcher (16) rolls along slideway (20) by supporting band dynamic bearing (19), drive rigid chain (8) (channel-section steel (17) and chain (18) riveting parts) linear reciprocating motion, drive the speed-changing chain group (25) with the speed-changing chain interlock of chain interlock, the big trochal disc (7) that drives axis (28) and be fixed on axis by slide key (24), roller clutch (26), key (23) rotates together.Drive rear axle by chain and rotate, drive right big shelves (14) (the selecting the bicycle part for use), the backpedalling brake body that are fixed on the rear axle by two screw nuts (13), holding screw (12) and rotate together, drive four-wheeled and advance.During the differential running, two trailing wheels can independently realize surmounting running.
When four-wheeled turned round, steering wheel rotation drove the minor sprocket (not shown) on the bearing circle vertical shaft, chain drive-belt (35) and driven sprocket (36), by joint (41), drivening rod (39), connecting arm (38), be rotating shaft, drive front-wheel (40) and turn to front-wheel vertical shaft (32).The length of connecting arm (38) is by two track fronts and the decision of front and rear wheel wheelbase.Support wheel (42) rolls along the chute (not shown) on the pipe link (34), does not shake to guarantee chain.
Connecting panel (34) closure dish vertical shaft and sprocket wheel (36) are connected on the car body by hinge-type hinge (4) then, before and after bearing circle needs during changing position, are that the length that rotating shaft changes sliding bar set (30) gets final product with the hinge hinge.The position mixes up the back by holding screw (31) screwed in place.
When the needs speed change, promote joystick forward, clutch driving lever (22) is lifted, drive rigid chain and break away from change wheel (25), the sprocket wheel that the joystick that swings then will be desired conversion by gear shift fork (27) pushes the desired location, is located by spring steel ball.The (not shown) joystick resets by torsion spring, drives the clutch driving lever rigid chain is placed on the sprocket wheel after the conversion, realizes speed change.
During reversing, joystick is pushed reverse gear position, pin reclaims, and drive rear axle and rotate backward, by holding screw, two spiral shell strand nuts, the right big shelves assembly in left side drives the trailing wheel reversing.(right big shelves assembly all is equipped with in backpedalling brake (15) left and right sides.）
Claims (5)
1, many people qudricycle, this installs mainly by footstep mechanism, and box of tricks, speed-changing mechanism, steering hardware are formed, and it is characterized in that the linear reciprocation foot pedal apparatus that footstep mechanism adopts footwear formula pedals (16), rigid chain (8) to form; The differential gear that box of tricks adopts the backshaft skin of pedal brake bike to form; Speed-changing mechanism adopts the fork type transmission system; Steering hardware adopts sprocket wheel chain-type steering hardware.
2, device according to claim 1 is characterized in that footwear formula pedal is supported on the slideway (20) by support and bearing (19); Rigid chain is made up of on channel-section steel (17) chain (18) riveting.
