Description

Four-wheel double pedal car

The utility model provides a kind of four-wheel double pedal car, belongs to technical field of transportation means.

Various manpower carts, three-wheel vehicle that existing market is popular all adopt traditional saddle type vehicle seat, and straight leg scrunches, and the single-wheel of front fork wushu turns to.This structural focus height, the stability extreme difference, direction is difficult for grasping, in case when emergency situation generation or driver were uncomfortable, driver self did not have the part of support, does harm rather than good during especially to the excessive driving of middle-aged and old hip lower compression, and racing to the time centre-of gravity shift, the time have roll-over accident to take place, cause personal injury, safety does not ensure.

The purpose of this utility model provides a kind of double four-wheeled bicycle of backrest flat seat backstroke that has for addressing the above problem to design exactly.

The utility model is to realize like this, car body is box, back seat is container down, two front lower place before and after two pedal drive wheels are separately positioned on, the chain wheel of preceding pedal drive wheel on chain and gap bridge power wheel and hind axle drives hind axle and trailing wheel, back foot drive wheel another chain wheel on chain and hind axle drives hind axle and trailing wheel, collapsible hood all is housed before and after the car body, to be lonely shape " T " word shape drive two front-wheels through direction vertical rod and steering track rod to direction device rotates in the same way, get on or off the bus and operate for ease of personnel, direction device and direction vertical rod are that hinge-coupled is fixed and is provided with locating dowel pin and carries out high low level and set.

The utility model has the advantages that: two-wheeled parallel steer driving stability is flexible before this car, the comfortable safety of the flat seat of backrest, can support each one of driver's health, backstroke scrunches, can exempt to rub, oppress, scrunch under the personal hip comfortable laborsaving, lower the center of gravity, driving safety is reliable, when raining winter protection, the collapsible hood of this car design-calculated nylon props, weather is just often collapsible to be put down, folding formula semicircle direction device can be regulated arbitrarily, two cover pedal actuating devices can use separately, also can drive jointly, make operation more convenient.
