Embodiment 1

[0032] like figure 1 - Figure 5 As shown, a single-wheel bicycle deceleration device provided by the present invention is characterized in that the device includes a base 1, a wheel 2 rotatably connected to the base 1 for driving the bicycle deceleration device to move, and a wheel 2 rotatably connected to the The cylinder 3 for placing the bicycle rear wheel 6 on the base 1, the device also includes a reduction transmission device 4 connected between the cylinder 3 and the wheel 2 and a connecting rod 5 connected between the base 1 and the bicycle frame 7, The reduction transmission device 4 includes a pinion 41 rotatably connected to the base 1 and fixed coaxially with the drum 3 , a large gear 42 rotatably connected to the base 1 and meshed with the pinion 41 for transmission, and rotatably connected to the base 1 The small sprocket 43 fixed on the top and coaxial with the large gear, the large sprocket 44 rotatably connected to the base 1 and coaxially fixed with the whe...

Embodiment 2

[0041] Such as Figure 6-8 As shown, the difference between Embodiment 2 and Embodiment 1 is that: the bicycle deceleration device further includes a roller 3 rotatably connected to the base 1 , and the bicycle rear wheel 6 is placed on the two rollers 3 . Setting two rollers 3 can make the transmission more stable, and the exercise intensity is greater, which is suitable for young people or people with better physical fitness to operate. And bicycle rear wheel 6 is pressed on two cylinders 3 at the same time, and the pressure acting on the surface of cylinder 3 is half smaller than the deceleration device of a cylinder, and the deformation of bicycle rear wheel 6 and cylinder 3 contact parts is also reduced a lot thereupon, so , which greatly improves the simulation of heavy riders operating.

Abstract

The invention relates to a single-wheel type bicycle speed reduction device. The device comprises a base, a wheel which is rotatably connected to the base and is used for driving the bicycle speed reduction device to move, and a roller which is rotatably connected to the base and is used for allowing a bicycle rear wheel to be placed thereon, and further comprises a speed reduction transmission device which is connected between the roller and the wheel, and a connecting rod which is connected between the base and a bicycle frame, wherein the lower end of the connecting rod is fixedly connectedto the front end of the base and the upper end of the connecting rod is detachably fixedly arranged on the bicycle frame. The device can conduct training in a mode of cooperating with the bicycle, sothat the bicycle riding speed can be reduced and a training effect can be achieved; and moreover, the reduction device is rigidly connected to the bicycle frame, so that good controllability and highresponse speed are guaranteed; the device is simple in structure, convenient to carry and low in making cost; in addition, the device, which is provided with one wheel only, can swing along with theswinging of the bicycle, so that a high simulation degree is achieved; and since the contact area between the wheel and the ground is small, the frictional resistance is also small, the bicycle speedreduction device is applicable to old people and children.

Description

technical field [0001] The invention relates to a deceleration device, in particular to a single-wheel bicycle deceleration device. Background technique [0002] As the pace of life continues to accelerate, people spend less and less time exercising, and fitness equipment has become the choice of more and more people, such as bicycle training devices. Chinese patent 201510212136.3 discloses a portable bicycle deceleration device, but the device not only weighs and bulky, inconvenient to carry, high manufacturing cost, and the supporting steering rod of the speed reduction device is movably connected with the bicycle frame, so the response speed is slow and the controllability is poor. In addition, the device is provided with two wheels, which cannot swing with the swing of the bicycle, and the degree of simulation is poor. The friction resistance between the two wheels and the ground is greater, and the operation is more strenuous, that is, the intensity of aerobic exercise...
