Abstract
The invention discloses a four-wheel bicycle for riding by double persons side by side. Two independent bicycle frames are welded together by a rigid connection mode to form an opening frame so as to ensure the strength. Two rear wheels are respectively connected with the frames through oscillating arms capable of swinging up and down, and the oscillating arms are connected with the frames through pin shafts to adjust the swinging amplitude of the oscillating arms; a spring damper can be arranged between the oscillating arms and the frames to ensure that four wheels can land under various situations and are stressed uniformly.
Description
Technical field
The present invention relates to a kind of double quadricycle of riding side by side.
Background technology
Usually tandem bicycle all is the two-wheeled cycle of riding in front and back, when riding, wants two people to cooperate each other and could keep driving stability.So owing to be that to take vehicle body before and after two people longer, the turn radius that goes is bigger.Quadricycle is that two people ride side by side, and four-wheel lands, and need not cooperate can smooth-ride, but quadricycle is owing to be at 4 and land, and can't let four wheels land simultaneously on ground during unfairness, so practical application is less.
Summary of the invention
The purpose of this invention is to provide a kind of double quadricycle of riding side by side, its trailing wheel adopts the swing arm type suspension, but the automatically regulating height is even to guarantee that four wheels also can land simultaneously under the roughness pavement situation, evenly stressed.
For carrying out above-mentioned purpose, the present invention adopts following technical scheme:
A kind of double quadricycle of riding side by side, be with two independently bicycle rack adopt the mode weld together that is rigidly connected, constitute degree of lip-rounding framework, to guarantee its intensity.Two trailing wheels link to each other with vehicle frame through the swing arm that can swing up and down separately, and swing arm links to each other through bearing pin with vehicle frame, in order to regulate the amplitude of fluctuation of swing arm, can both land under various situation to guarantee four wheels, and are evenly stressed.
In order to reduce the vibrations that the swing arm swing causes, can between swing arm and vehicle frame, adorn a spring damper.
Further, the inwall of two front vehicle forks of quadricycle of the present invention can connect through tie rod linkage, and tie rod linkage comprises intermediate rod and spindle arm, and the intermediate rod two ends connect spindle arm with articulated manner, and spindle arm is fixed on the inwall of front vehicle fork.
Quadricycle of the present invention, but trailing wheel automatically regulating height, even it is to guarantee that four wheels also can land simultaneously under the roughness pavement situation, evenly stressed.
Description of drawings
Fig. 1 is the axonometric drawing of quadricycle of the present invention;
Fig. 2 is the front view of quadricycle of the present invention;
Among the figure, 1 is intermediate rod, and 2 is spindle arm, and 3 is handlebar, and 4 is front cross rail, and 5 is vehicle frame, and 6 is vehicle seat, and 7 is the back shelf, and 8 is rear wheel, and 9 is the rear suspension swing arm, and 10 is spring damper, and 11 is rear suspension swing arm bearing pin, and 12 is front fork, and 13 is front vehicle wheel.
The specific embodiment
Below in conjunction with specific embodiment the present invention is set forth in detail.
As depicted in figs. 1 and 2; A kind of double quadricycle of riding side by side comprises intermediate rod 1, spindle arm 2 (2), handlebar 3 (2), front cross rail 4, vehicle frame 5 (2), vehicle seat 6 (2), back shelf 7, rear wheel 8 (2), rear suspension swing arm 9 (2), spring damper 10 (2), rear suspension swing arm bearing pin 11 (2), front fork 12 (2), front vehicle wheel 13 (2).Pedal, sprocket wheel, the chain of ordinary bicycle are housed respectively on said 2 vehicle frames 5, and can drive the trailing wheel rotation through rotating pedal.Said 2 vehicle frame 5 front ends and front cross rail 4 weld togethers, shape of the mouth as one speaks framed structure is formed in rear end and back shelf 7 weld togethers.Said front fork 12 adopts the pipe connection mode to be installed in the front end pipe of vehicle frame 5, and is free to rotate.Said handlebar 3 is installed in the upper end of front fork 12, rotates handlebar 3 may command front forks 12 and rotates.One end of said spindle arm 2 is welded on the yoke of front fork 12 inboards, and the other end links together with articulated manner and intermediate rod 1, forms trapezium structure, and two front-wheels 13 rotate to satisfy the requirement that turns to of four-wheeled by different corners when turning to assurance.Said rear wheel 8 is installed in the rear end of rear suspension swing arm 9.Said rear suspension swing arm 9 front ends are fixed on vehicle frame 5 bottoms by rear suspension swing arm bearing pin 11, and can swing up and down around suspension swing arm bearing pin 11.The two ends of said spring damper 10 adopt articulated manner to link to each other with rear suspension swing arm 9 with vehicle frame 5 respectively; Spring damper 10 is formed triangular structure with vehicle frame 5 and rear suspension swing arm 9; Spring when bearing load changes in the spring damper 10 is compressible, suspension swing arm 9 can be done swing up and down.
When reality is used, can a people or two people ride over respectively on the vehicle seat 6, walking vehicle turns to 3 controls and rides.Meet ground unfairness place, spring damper 10 effect under rear suspension swing arm 9 upwards or lower swing, go to guarantee that rear wheel 8 can both land at any time.Can put belongings on the back shelf 7, or repack seat into and supply the juvenile to take.Because being four-wheel, bicycle lands so riding stability is better.
