Description

Walking tetracycle

Technical field

The utility model relates to the walking-replacing tool technical field, especially relates to a kind of Walking tetracycle.

Background technology

Bicycle is a walking-replacing tool indispensable during people live as conventional vehicles.At present, along with the raising of technological advance and people's living standard, bicycle has been endowed more function.Such as, as a kind of instrument of taking exercises.But in terms of overall, no matter bicycle is as walking-replacing tool or as fitness tool, and its basic structure and operating mode do not have too much variation, feel comparatively uninteresting when causing the user to use.Therefore be necessary to improve.

The utility model content

To the deficiency that above-mentioned prior art exists, the purpose of the utility model provides a kind of Walking tetracycle, and it has structure and operating mode is different from standard bicycle fully, thereby can make the user continue to keep using the characteristics of enjoyment.

To achieve these goals, the technical scheme that the utility model adopted is: Walking tetracycle comprises vehicle frame; The front end of vehicle frame is hinged with headstock, and headstock is provided with front-wheel, simultaneously; The rear end of vehicle frame is provided with trailing wheel, and trailing wheel is provided with brake gear, and the middle part of said vehicle frame is provided with front roll and back roll; Be connected with the band of running between front roll and the back roll, simultaneously, back roll is connected with trailing wheel.

Be provided with at least 1 intermediate calender rolls between said front roll and the back roll.

The external diameter of said intermediate calender rolls is less than any one external diameter of front roll and back roll.

The angle a of the upper surface of said running band and horizontal surface is: 15 °≤a≤30 °

Be provided with transmission system between said back roll and the trailing wheel.

Said transmission system is a change gear transmission.

Said brake gear is a disc brake.

Be provided with shock absorption device between said vehicle frame and the headstock.

After adopting said structure, the utility model is compared the advantage that is had with prior art and is: 1, can continue to keep the person taking exercise to use the enjoyment of bicycle.The Walking tetracycle of the utility model, its structure have been made great change on power input device for traditional bicycle.That is: with original mode that drives chain or the rotation of other transmission medium drive trailing wheel through bicycle pedal; Change into through the user and on running is with, walks about or run; The drive back roll rotates, and moves ahead thereby the mode that the drive trailing wheel rotates drives bicycle.The function of treadmill and bicycle has been carried out organic combination, made the user keep the permanent enjoyment of using bicycle.2, use is comfortable.Be provided with at least one intermediate calender rolls between the forward and backward cylinder, like this, the user in use, the foot bottom pressure is comparatively even.After the optimization, be provided with shock absorption device between headstock and the vehicle frame, like this, when the user walked about or runs, foot can not receive bigger vibrations.3, rational in infrastructure, use easily.The front roll of the Walking tetracycle of the utility model or the external diameter of back roll are all greater than intermediate calender rolls, and like this, that runs and be with can not contact between the partial sum cylinder of cylinder downside, thereby have reduced the unnecessary friction between band and the cylinder of running.The top of running band is to have angle between plane and this plane and the horizontal surface, and like this, the user runs to be with the auxiliary output torque that provides.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further specified:

Fig. 1 is the three-dimensional decomposition texture scheme drawing of the embodiment of the utility model;

Fig. 2 is the perspective view of the embodiment of the utility model;

Fig. 3 is the main TV structure scheme drawing of the utility model.

Among the figure: 1, vehicle frame; 2, front-wheel; 3, trailing wheel; 4, front roll; 5, intermediate calender rolls; 6, back roll; 7, running band; 8, transmission system; 9, brake gear; 10, headstock; 11, shock absorption device.

The specific embodiment

The following stated is merely the preferred embodiment of the utility model, does not therefore limit the protection domain of the utility model.

Embodiment, see Fig. 1, Fig. 2 and shown in Figure 3: Walking tetracycle comprises vehicle frame 1.Concrete, vehicle frame 1 is square frame shape.The front end of vehicle frame 1 is hinged with headstock 10.Headstock 10 is provided with front-wheel 2.Certainly, the top of front-wheel 2 is connected with parts such as handrail.Simultaneously, the rear end of vehicle frame 1 is provided with trailing wheel 3, and trailing wheel 3 is provided with brake gear 9.The middle part of vehicle frame 1 is articulated with front roll 4 and back roll 6.Being connected with between front roll 4 and the back roll 6 runs is with 7.Simultaneously, back roll 6 is connected with trailing wheel 3.Certainly, back roll 6 and trailing wheel 3 ways of connecting can take trailing wheel 3 to be directly fixed on any common mode at two ends etc. of the S. A. of back roll 6.In order to increase the inner support of running, then be articulated with at least 1 intermediate calender rolls 5 between front roll 4 and the back roll 6 with 7.Obviously, all cylinders are parallel mutually.For fear of the part that be positioned at downside of running with the lasting intermediate calender rolls 5 that rubs of 7 the part that is positioned at the cylinder downside, then the external diameter of intermediate calender rolls 5 is less than any one external diameter in front roll 4 and the back roll 6.Like this, no matter run and be with 7 to have what kind of tensile force, when the upper side of front roll 4, intermediate calender rolls 5, bottom roll 6 has same plane, run with 7 be positioned at the cylinder downside part all can not contact with the part that intermediate calender rolls 5 is positioned at downside.In order to make the user when running is with 7 to walk about or run, can make full use of self gravitation, running with 7 the upper surface and the angle a of horizontal surface is: 15 °≤a≤30 °.Like this, the user has downward potential energy, can make full use of from being with 7 output torques to provide auxiliary as running.Further, be provided with transmission system 8 between back roll 6 and the trailing wheel 3.That is: rear roller 6 is connected with trailing wheel 3 through transmission system 8.Transmission system 8 can be taked any common such as modes such as chain speed changes.Optimize, transmission system 8 can be taked change gear transmission.In order to increase the effect of brake, brake gear 9 is taked disc brake.In order to increase the traveling comfort of use, be connected with shock absorption device 11 between vehicle frame 1 and the headstock 10.

The course of action of the utility model: the user stands in to run to be with and walks about on 7 or run, and driving runs is with 7 to rotate.Running is with 7 to drive front wheel 4, middle roller 5, rear roller 6 rotations.Rear roller 6 drives trailing wheel 3 through transmission system 8 and rotates, and Walking tetracycle is advanced.

Bicycle, disc brake are widely-used at present, and other structure is identical with prior art with principle, repeats no more here.
