Abstract
The utility model discloses a tandem bicycle and relates to the technical field of bicycle manufacturing. The tandem bicycle comprises a frame, a front transmission mechanism and a rear transmission mechanism, wherein the rear transmission mechanism comprises a first gear transmission mechanism and a second gear transmission mechanism, the first gear transmission mechanism comprises a first pinion, a second bull gear, a third pinion and a fourth bull gear, the first pinion is fixedly connected to a rear wheel axle, the second bull gear and the third pinion are arranged in a coaxial and integrated mode, the first pinion is meshed with the second bull gear, the third pinion is meshed with the fourth bull gear, and a treading connection rod is fixedly connected to the fourth bull gear; the structure of the second gear transmission mechanism is identical to the structure of the first gear transmission gear, the first gear transmission mechanism and the second gear transmission mechanism are oppositely arranged on the other side of the frame, a treading connection rod is fixedly connected to a gear opposite to the fourth bull gear, and the rear wheel rotating speed provided by the rear transmission mechanism is higher than the rear wheel rotating speed provided by the front transmission mechanism. The tandem bicycle can be ridden alternately by two riders, the speed can be adjusted freely, and people feel relaxed while ridding.
Description
Technical field
The utility model relates to a kind of manufacturing technology field of bicycle, particularly a kind of manufacturing technology field of tandem bicycle.
Background technology
Existing tandem bicycle, while riding, two people ride and need exert oneself simultaneously, and need basically identical harmony, ride and comparatively consume power.
Utility model content
The utility model object is that speed regulates freely, and two people can substitute and ride, the tandem bicycle easily of riding.
The utility model comprises vehicle frame, front transmission mechanism, rear transmission device, described front transmission mechanism comprises chain wheel, flywheel, stampede body, described stampede body and described chain wheel are connected, described chain wheel is connected on described vehicle frame, described flywheel is fixedly connected on hind axle, and described chain wheel is connected by chain gear with described flywheel, described rear transmission device comprises the first gear drive, the second gear drive, described the first gear drive comprises the first miniature gears, second largest gear, third pinion, the fourth-largest gear, described the first miniature gears is fixedly connected on described hind axle, described second largest gear is coaxial and be wholely set with described third pinion, described second largest gear, third pinion is connected on described vehicle frame by a rotating shaft, described the first miniature gears and described second largest gear engagement, described the fourth-largest gear and the engagement of described third pinion, described the fourth-largest gear is connected on vehicle frame by rotating shaft, on described the fourth-largest gear, be fixedly connected with one and trample connecting rod, described the second gear drive is identical with described the first gear drive structure and be oppositely disposed in the opposite side of described vehicle frame, on the gear relative with described the fourth-largest gear, be fixedly connected with one and trample connecting rod, the angle of trampling between connecting rod of described both sides is 180 °, the rear wheel rotation speed that described rear transmission device provides is greater than the rear wheel rotation speed that described front transmission mechanism provides.
Bicyclist before the utility model goes top bicycle to move ahead by front transmission mechanism, its driving is below ridden by rear transmission device, the rear wheel rotation speed providing due to rear transmission device is greater than the rear wheel rotation speed that described front transmission mechanism provides, such as the chain wheel of front transmission mechanism can offer the rotating speed of 6 times of trailing wheels, then transmission device offers 9 times of rotating speeds of trailing wheel by the multistage acceleration of gear, bicyclist so is above as main bicyclist, its circle of riding, rear bicyclist is without the circle of stepping on, it rides lighter, if bicyclist is below as main bicyclist, it can provide speed faster, bicyclist above even can not step on, all can move ahead, this tandem bicycle two bicyclists can alternately ride, speed free adjustment, and two kinds of speed all can be used as main (inferior) speed, ride easily.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, this tandem bicycle comprises vehicle frame 1, front transmission mechanism 2, rear transmission device 7, front transmission mechanism 2 comprises chain wheel 3, flywheel 4, stampede body 5, stampede body 5 is connected with chain wheel 3, chain wheel 3 is connected on vehicle frame 1, flywheel 4 is fixedly connected on hind axle 6, and chain wheel 3 is connected by chain gear with flywheel 4, rear transmission device 7 comprises the first gear drive 8, the second gear drive 9, the first gear drive 8 comprises the first miniature gears 10, second largest gear 11, third pinion 12, the fourth-largest gear 13, the first miniature gears 10 is fixedly connected on hind axle 6, second largest gear 11 is coaxial and be wholely set with third pinion 12, second largest gear 11, third pinion 12 is connected on vehicle frame 1 by a rotating shaft, the first miniature gears 10 and second largest gear 11 engagements, the fourth-largest gear 13 and third pinion 12 engagements, the fourth-largest gear 13 is connected on vehicle frame 1 by rotating shaft, on the fourth-largest gear 13, be fixedly connected with one and trample connecting rod 14, the second gear drive 9 is identical with the first gear drive 8 structures and be oppositely disposed in the opposite side of vehicle frame 1, is fixedly connected with one and tramples connecting rod 15 on the gear relative with the fourth-largest gear 13, and the angle of trampling between connecting rod 14,15 of both sides is 180 °, the rear wheel rotation speed that rear transmission device 7 provides is greater than the rear wheel rotation speed that front transmission mechanism 2 provides.
