Problems solved by technology

[0003] The present invention is a research aimed at the above-mentioned problems, and its purpose is to replace the original single-beam three-wheel skating drive bicycle with double beams and four wheels so as to solve the problem of unstable operation; and the reciprocating chain drive structure, so that the push and pull of the rowing rod and the chain disc can fully play the driving role in the reciprocating operation; The length of the rod can be expanded and contracted at any time according to the requirements of the speed of the rod, so that the rod becomes a variable force and speed-changing rod; the sliding seat is changed from being indirectly driven only by the rod to being independently and directly driven, achieving a performance beyond the existing two-wheel drive The speed, endurance and towing capacity of the pedal bicycle create a single or double four-wheel skating drive bicycle with multiple purposes such as energy saving, environmental protection, labor saving, fun, transportation, competition, fitness, etc.

Embodiment Construction

[0026] As shown in Fig. 1, adopt double parallel middle beam [1], the front car insert [5] that double-wheel double front axle [2] is fixedly equipped with at the front end of double parallel middle beam [1], its rear end is installed with two The rear axle [13] of the wheel is respectively equipped with a pedal steering device, a casing telescoping paddle bar variable force push-pull drive device, and a sliding seat drive device on the double parallel center beam [1]:

[0027] Pedal steering device: the front car insert [5] has three ends, upper, left and right, and its upper end is fixed with the front end of the double parallel center beam [1], and the left and right ends of the front car insert [5] beam are respectively connected with The left and right front axles [2] equipped with front wheels are connected and parallel to the front axle connecting rods [11] connected to the left and right front axles [2], and the connecting rods [4] are installed on the double parallel c...

Abstract

A 4-wheel vehicle driven by two hands in a mode similar to rowing and ridden by one or two persons is composed of parallel two central beams, front fork, front axle with two front wheels, back axle with two back wheels, pedal-type steering mechanism, sleeve tube-type telescopic rowing rod mechanism, and slide saddle driver.

Description

Technical field: [0001] The invention relates to a four-wheel bicycle device, in particular to a four-wheel skating-driven single or tandem bicycle that can realize fun, fitness and competitive sports. Background technique:: [0002] At present, the pull rod type and crank type tricycles have become good helpers for the disabled, but the steering and driving force of this tricycle all come from both arms, and both feet are idle. The car seat is fixed, the range of force is small, and it is prone to fatigue, and its speed, endurance and towing capacity are all difficult to exceed that of a pedal bicycle. Therefore, the fun and practical value of promotion of its competitive sports are lost. Although the three-wheel sliding drive bicycle disclosed by us previously solved the above-mentioned problems, there were single beams, insufficient stability of the three-wheel body in operation, insufficient simplification of the pedal steering device, and insufficient function of the c...
