Abstract

The invention relates to a tug-of-war sports bicycle, which integrates body building and competition into a whole. According to the invention, bicycle bodies of two bicycles are integrated together back by back to form a four-wheel bicycle; two relatively independent transmission mechanisms are reserved; two riders sit in the reverse direction, and the riding directions are opposite; when the two riders respectively tread pedals of the bicycle to move, the bicycle moves along, and the moving speed and direction of the bicycle depend on the treading speed difference of the two riders; when one rider wants the bicycle to move towards the self riding direction, the treading speed needs to be more than the treading speed of the other rider, therefore two treading parties form an opponent competition relation; and destination points are respectively arranged in front of the two riders, and the rider who reaches the termination point wins. The competition form is similar to a tug-of-war match, and therefore the invention is called as the tug-of-war sports bicycle.

Description

The tug-of-war lifecycle

Technical field type of the present invention relates to bicycle, relates in particular to the two-motor drive bicycle.

The background technology bicycle also is bicycle, mainly as the vehicle, also generally as fitness tool; It is a sports events; But during as fitness tool or as sports events, usually receive the restriction in place with traditional bicycle, then there is high requirement in the place during especially as sports events; The indoor bicycle that occurs in the market, its function only is confined to body-building.

Summary of the invention the present invention proposes a kind of bicycle that integrates body-building and contest, and this car combines two bicycle car body dos-s, constitutes the bicycle of a four-wheel form, keeps two relatively independent transmission devices; Two people by bike oppositely sit, and the direction of driving is also opposite, when two people step on the bicycle pedal motion separately; Bicycle meeting movement therewith, the speed of its motion and direction depend on two cyclists velocity contrast to pedal, people by bike wants the ride direction motion of bicycle to oneself; Speed is greater than another person's speed to pedal to pedal, and therefore, both sides have to pedal just become adversary's contest relation each other; Terminal point is respectively established in front both sides, and who reaches home, and who just wins; This contest form class is similar to tug-of-war, therefore, is called the tug-of-war lifecycle.

Technical scheme is, with the car body of two bicycles with back-to-back form with their trailing wheels partly combine form one after wheel mechanism, two bicycle car bodies keep separately independently Power train; Wheel mechanism after the common transmission drives the bicycle motion through the back wheel mechanism, and a box of tricks is arranged in the back wheel mechanism; Box of tricks has two driving members; A driven member, two driving members are respectively by the Power train transmission of two bicycles, and driven member connects hind axle; Hind axle prolongs vertically, and two trailing wheels are contained in the two ends of hind axle.

Beneficial effect can body-building, again can contest, and less demanding to the place just can carry out contest or exercise under the condition that does not need big athletic ground, the meaning of succession and this traditional ethnic sports campaign of development tug-of-war is arranged.

Appended drawings 1 be specific embodiment overlook train figure, accompanying drawing 2 is hind axle mechanism partial view of accompanying drawing 1.

Among the figure: 1. bevel planet gear; 2. sun finishing bevel gear cuter; 3. sprocket shaft; 4. rotary damper outer ring; 5. trailing wheel; 6. rotary damper inner ring; 7. sprocket wheel; 8. bevel planet gear frame; 9. chain; 10. chain wheel; 11. sun finishing bevel gear cuter; 12. sprocket shaft; 13. rotary damper inner ring; 14. trailing wheel; 15. rotary damper outer ring; 16. sprocket wheel; 17. hind axle; 18. chain; 19. chain wheel; A. car body; B. car body.

It is following that specific embodiment specifies specific embodiment with reference to accompanying drawing 1,2, and present embodiment comprises identical chain wheel driving mechanism of two-strip structure and back wheel mechanism, the tooth of chain 9 engagement chain wheels 10 and sprocket wheel 7; Constitute a Power train; The tooth of chain 18 engagement chain wheels 19 and sprocket wheel 16 constitutes another Power train, and back wheel mechanism comprises awl tooth planetary gear train and hind axle; Sun finishing

bevel gear cuter

2,11 and bevel planet gear 1, bevel planet gear frame 8 are formed bevel planet gear system; Sprocket wheel 7 is connected on the sprocket shaft 3, and sprocket shaft 3 connects sun finishing bevel gear cuter 2, sun finishing bevel gear cuter 2 and bevel planet gear 1 engagement; Sprocket wheel 16 is connected on the sprocket shaft 12; Sprocket shaft 12 connects sun finishing bevel gear cuter 11; Sun finishing bevel gear cuter 11 and bevel planet gear 1 engagement, bevel planet gear frame 8 is connected with hind axle 17, and

sprocket shaft

3,12 all is a hollow shaft; Hind axle 17

passes sprocket shaft

3,12 and extends axially, and at the two ends of hind axle 17 two

trailing wheels

5,14 is installed.

Wheel mechanism is provided with two rotary dampers to present embodiment in the back, rotary damper inner ring 6 connection chain wheel shafts 3, and rotary damper outer ring 4 connects vehicle frame; Rotary damper inner ring 13 connection chain wheel shafts 12, rotary damper outer ring 15 connects vehicle frame.

Chain wheel driving mechanism in the present embodiment is the Power train described in the technical scheme.

Bevel planet gear system is the box of tricks described in the technical scheme in the present embodiment, two sun finishing bevel gear cuters the 2, the 11st, and the driving member of box of tricks, bevel planet gear frame 8 are driven members of box of tricks.

Be A, two bicycle car bodies of B in the present embodiment frame of broken lines, car body A and car body B are back-to-back form.

Described car body A or car body B refer to the bicycle element body that vehicle frame, wheel, tap, handle, pedal, seat are formed.

Though described trailing wheel is in the midway location of tug-of-war car, with respect to the cyclist, still be in back location, so still be called trailing wheel in this manual.
