Ultra-miniature double-crankshaft front drive vehicle

Abstract

The invention relates to an ultramicro double-crank shaft front drive vehicle, which is characterized in that crank truncation of a front drive chainwheel is converted into crankshaft connection and even sleeve extension; the track of a foot pedal is greatly reduced, so that forward moving and pedaling are more comfortable and labor-saving; the length and the height of a vehicle body are shrunk into below 70 centimeters, so that the ultramicro double-crank shaft front drive vehicle is folded, and is small, portable, light, cheap, safe and practical, is easy to manufacture, and is actually taken as a mobile chair, an easy bed, an ultramicro house, a luggage barrow and a small truck and can transport heavy cargoes; the inside of the ltramicro double-crank shaft front drive vehicle is provided with a rain cover support which is quick to assemble and disassemble; a thwart is a box and can be filled with a notebook computer; and a bag box can store more articles, and is used by people to learn and work at any place. The ultramicro double-crank shaft front drive vehicle is safe, comfortable, multifunctional and incomparable, particularly has superior capacities of pivot steering, quick advance and retreat, easy obstacle crossing, independent and stable storey-ascending and room entrance, capability of going to any place such as buses, underground railways and so on, convenient traveling, and elimination of all the troubles of walking and standing for a long time, can greatly solve various problems of traffic jam and inconvenient parking, generates a green, high-efficiency, coherent and complete traffic means, deeply improves the livelihood and the wisdom of the people, can be used by any person, is beneficial to all ages, is about to be quickly popular worldwide, and generates good effect.

Description

technology field; [0001] Bicycles, electric vehicles, rickshaws, tricycles, motorcycles, vehicles for the disabled Background technique: [0002] Motorcycles, electric vehicles, tricycles, and bicycles are the most popular light vehicles with huge quantities. However, the previous bicycles all adopt driving and control structures such as pedaling force, the body is tall and bulky, the safety, comfort and mobility are low, it is extremely inconvenient to store and carry, and there is no ideal multiple functions of sitting and carrying goods. Motorcycles are heavier and bigger, and the occupants are more likely to rush forward and fly out, all of which require major improvements in structural performance. Invention content: [0003] The original pedal crank of the front wheel driving the front sprocket is cut off and lengthened to form a new crankshaft connection, and both sections can be made into an extension spring casing telescopic structure. In this way, the stirrup s...
