Abstract

The utility model relates to a treading light cycle, which comprises a cycle frame, wheels, a ratchet mechanism, a supporting tube for cycle handles. The utility model is characterized in that one end of a right and a left pedal rods is connected with the cycle frame via a connector, and the other end is provided with pedals; the right and the left pedal rods are connected with a spring and the ratchet mechanism via a chain or a rope belt; the cycle is driven to move forwards by that the ratchet mechanism is driven by the right and the left pedal rods to rotate. The treading light cycle of the utility model has reasonable design and novel structure, the traditional driving means of crank rotation type is replaced by the driving means of pedal rod reciprocating type, and thus the utility model has the handy body, and the cabinet body after folded. The riding posture is more coincident with the science of the human body motion, so as to improve the riding effect greatly, and the utility model is easy, comfortable and convenient.

Description

Step on capable Light-duty Vehicle

Technical field:

The utility model relates to the manpower transportation, especially a kind ofly steps on capable Light-duty Vehicle.

Background technology:

In existing manpower transportation, multiwheel vehicles such as bicycle and the three-wheel vehicle that goes out by the bicycle derivation, four-wheeled, its driver train all is a crank and chain-wheel swinging driver train of having applied mechanically Irishman Lawson invention in 1879.Because the next dead point that all has is gone up by the inherent limitation of crank up formula drive configuration when rotating as crank, the length limited of crank makes the effect of riding be difficult to improve again; And for example be subjected to the limitation of said structure, make height, length, center of gravity and the weight of vehicle body be difficult to reduce again, folding aftercarriage is long-pending to be difficult to dwindle again, and the traveling comfort of riding and convenience are difficult to improve again.

Summary of the invention:

The purpose of this utility model is exactly to substitute traditional crank up formula driver train to pedal the reciprocating type driver train of bar, thereby provide a kind of reasonable in design, novel structure, car body is light and handy, effect is higher, it is small and exquisite to fold, it is more light to ride, and steps on capable Light-duty Vehicle more easily.

The technical scheme of determining thes contents are as follows to achieve these goals: the utility model is stepped on capable Light-duty Vehicle and is comprised vehicle frame, wheel, ratchet device, the handlebar support tube, be characterized in: about pedal bar an end link to each other with vehicle frame respectively by connecting device, about pedal bar the other end pedal all is housed, about pedal bar and link to each other with left and right sides ratchet device respectively by left and right sides chain or rope band, left and right sides ratchet device all links to each other with wheel, the other end of left and right sides chain or rope band links to each other with left and right sides spring respectively, the other end of left and right sides spring is separately fixed on the vehicle frame, and handlebar support tube and vehicle frame saddle support tube are respectively equipped with can be backward and folding forward hinge.

The utility model is stepped on capable Light-duty Vehicle basic functional principle: when people ride, bipod is pedaled bar about pedaling respectively and stepping on, and then the pulling and pedal left and right sides chain or the rope band that bar links to each other, drive the left and right sides ratchet device that links to each other with wheel again, thereby car is moved ahead, left and right sides pin pumpback then, about pedal bar and be subjected to the pulling force of spring and self-return thereupon, left and right sides pin has just been finished one and has been pedaled the motion circle phase of stepping on like this.

The major advantage that the utility model is stepped on capable Light-duty Vehicle is: because type of drive is changed into by traditional crank up formula driver train and pedals the reciprocating type driver train of bar, the feasible driving effect of riding further improves, simultaneously because the change of said mechanism, it is longitudinal folding to make the vehicle body folding mode change vehicle body into from traditional vehicle body side-foldable, and the folding aftercarriage is more small and exquisite; The change of body construction makes the position ride also meet the science of human motion more, and the height of vehicle body, length, center of gravity and weight further reduce, and vehicle body is more light and handy, thus make ride more light, comfortable and convenient.

The specific embodiment:

Step on capable Light-duty Vehicle and comprise vehicle frame 1, wheel 2, left and right sides ratchet device 3,4, handlebar support tube 5, be characterized in: about pedal bar 6,7 an end link to each other with vehicle frame 1 respectively by connecting device, about pedal bar 6,7 the other end pedal all is housed, about pedal bar 6,7 and link to each other with left and right sides ratchet device 3,4 respectively by left and right sides chain (or rope band) 8,9, left and right sides ratchet device 3,4 all links to each other with wheel 2, the other end of left and right sides chain or rope band links to each other with left and right sides spring 10,11 respectively, and the other end of left and right sides spring is fixed on the vehicle frame 1 respectively.

Embodiment 1: pedal about an end of left and right sides chain (or rope band) 8,9 is separately fixed on the bar 6,7, left and right sides chain (or rope band) 8,9 is pile warp left and right sides ratchet device 3,4 respectively, left and right sides ratchet device 3,4 all links to each other with wheel 2, the other end of left and right sides chain (or rope band) 8,9 links to each other with left and right sides spring 10,11 respectively, and the other end of left and right sides spring 10,11 is fixed on the vehicle frame 1 respectively.

Embodiment 2: left and right sides chain (or rope band) 8, about being separately fixed at, an end of 9 pedals bar 6, on 7, left and right sides chain (or rope band) 8,9 respectively pile warp be located at left and right sides pulley 12 on the vehicle frame 1, after 13, distinguish pile warp left and right sides ratchet device 3 again, 4, left and right sides ratchet device 3.4 all links to each other with wheel 2, left and right sides chain (or rope band) 8,9 the other end respectively with left and right sides spring 10,11 link to each other, left and right sides spring 10,11 the other end is fixed on the vehicle frame 1 respectively, handlebar support tube 5 is provided with rearward the folding hinge 14 of folding down, and vehicle frame 1 saddle support tube is provided with forwards the folding hinge 15 of folding down.
