Abstract
A tricycle with an extended rocker arm is composed of frame, front, back and middle axles, chain wheel, chain and crank, central axle and front chain wheel (400 mm) arranged at the position of original central axle, chain connected to said chain wheel, extended right and left rockerarms similar to ratchet spanner at both ends of central axle, ratchet unit consisting of ratchet wheel, pawl and pawl spring, axle joint on flat fork, central axle bowl, central axle stop, steel ball, supporting central axle, left and right rockers, steel cable connected between said left and right rockers, pulley axle supported grooved wheel on upper transverse plate for supporting steel cable, steel cable clamp at both ends of rope and connected between left and right rockers, and pedal for moving up in right slideway when left rocker arm moves down in left slideway, instead, the pedal is used for up-and-down movement, and the pedal is labor-saving because the rocker arm is lengthened.
Description
Technical field
The utility model relates to a kind of three-wheel vehicle, particularly relates to a kind of lengthening rocking handle three-wheel vehicle.
Background technology
The three-wheel vehicle of selling in the market that is using with people all is to drive sprocket wheel with crank, the chain rotation drives the trailing wheel rotation and moves ahead, this three-wheel vehicle is using the time spent, cyclist's both feet otherwise the rotation that stops are stepped on and are pedaled axis, make the sprocket wheel rotation, drive the trailing wheel rotation by chain and move ahead, the time is under a strain once long people's sensation both feet, and require great effort very much, and speed is also very slow.
Summary of the invention
The purpose of this utility model is at the problem of above existence, a kind of lengthening rocking arm up-and-down movement is provided, trishaw, this structure is foot-operated again not to be needed cyclist's both feet not stop to rotatablely move to step on to pedal crank and drives the sprocket wheel rotation, pedal the rocking arm up-and-down movement and only need both feet to step on, adopt escapement, thus since the rocking arm lengthening step on pedal very laborsaving.Speed is also very fast.
The purpose of this utility model is achieved in that and mainly comprises vehicle frame, before, after, in three, sprocket wheel, chain and crank, pedal, flywheel and preceding, rear wheel, the position of former axis move backward 400mm be provided with axis and before sprocket wheel, connect the back sprocket wheel by chain, the right rocking arm of lengthening and the left rocking arm of similar ratchet wrench are set at the axis two ends, on the rocking arm of the left and right sides, pedal are set, be provided with ratchet at the rocking arm root, ratchet, the escapement that click spring is formed, shaft adapter is arranged on the chain stay, and shaft adapter is provided with bottom bracket cup, middle axle bumper, steel ball, supporting axis, left rocking arm, right rocking arm is connected by steel rope, on upper cross plate, be provided with sheave shaft carries left sheave, right sheave supporting steel-cable, two of rope is provided with the steel cable card and is connected with left and right sides rocking arm; When left rocking arm moved downward in left slideway, at this moment, right rocking arm is upward movement in right slideway; The slideway lower end is provided with the slideway baffle plate in the left and right sides; Left and right sides slideway is provided with lower cross plate and connects, and is fixed on the chain stay.
The escapement upward movement of described rocking arm root is a neutral, moves downward to be the reinforcing retaining.
The utility model has the advantages that: simple in structure, convenient and practical, structure is provided with rationally, creative, improve former three-wheel vehicle and make circular movement with foot-operated pedal, move up and down and change into foot-operated pedal, because the lengthening of rocking arm, so pedal very laborsavingly, the front and back sprocket wheel adopts same size, and institute's speed is also very fast.
