Description
The utility model relates to a kind of bicycle, is meant the totally-enclosed bicycle of the laborsaving high speed of weather proof especially.
Bicycle now, though light and handy, attractive in appearance, practical pollution-free, also have tangible weak point: the Exposure to Sunlight that can not resist the elements, the effort of going up a slope, long-distance riding with too tired, speed are waited too slowly.
The purpose of this utility model is to provide the laborsaving high speed of a kind of weather proof totally-enclosed bicycle.
Before taking scheme to comprise for achieving the above object to be installed in triangular frame respectively, the direction lever of rear end and trailing wheel, lower end at direction lever connects front-wheel, there is brake at middle part at triangular frame, a sleeperette chair support is arranged at an upper portion thereof, it is characterized in that on support, utilizing pedal spindle that a shuttle-type left side is installed perpendicular to the triangular frame front portion, right threading and multiplying wheel, on a left side, the connecting portion of right threading and pedal spindle is provided with ratchet, on support, sprocket shaft is installed at following two ends respectively, and the installation hinge wheel reaches and multiplying wheel ingear miniature gears on sprocket shaft, on sprocket shaft, connect hinge wheel and speed change small flywheel, wherein the speed change small flywheel utilizes chain to be connected with hinge wheel, and the gear shift flywheel on hinge wheel utilizes chain and is installed in hind axle is connected.
Its another feature is to utilize bearing seat that safety wheel is installed in the both sides, middle part of triangular frame, at the built-in torque spring of bearing seat, between safety wheel and brake cable wire is arranged.
Another feature of the present utility model is the anterior captive joint wind and rain cover front portion at triangular frame, open portion after its rear portion with attachment point is hinged point articulated wind and rain cover, form an osed top case, and an organism glass form that makes things convenient for the rider to watch is set in the front portion of back open portion.
The utility model has the advantages that: the propulsive force that 1, increases bicycle.Its way is the lengthening foot-driven lever.The utility model is lengthened to foot-driven lever more than 45 centimetres from original 18 centimetres.2, gather way.The utility model adopts comparatively simple speed increasing mechanism: utilize gear and sprocket wheel to change the purpose that speed change reaches speedup mutually.Concrete way: on the long foot-operated miniature gears that at first starts a big gear wheel, driven by big gear wheel is coaxial a hinge wheel is housed, hinge wheel passes to power on the small flywheel of its below by chain, be positioned at its another coaxial hinge wheel thereby drive, this is taken turns power is directly passed to 5 grades of change wheels that are contained in trailing wheel.Promptly by the foot-operated power that sends through 3 speedups, its speed surpasses ordinary bicycle more than 4 times.Lengthening foot-driven lever and gear, sprocket wheel are contained in the vehicle frame front portion near the front-wheel place.A foot-driven lever and an axle junction built-in ratchet, foot-operated is that the mode of swing produces power.The driver is in half and sits the state of crouching.3, comfortable.Be the following measure of comfortable employing: half sits the sofa arm-chair that crouches, and its backrest angle is adjustable.Closed wind and rain cover is divided into two parts to be formed, anterior fixing, and latter half of have an individual fulcrum, can do the flip-up style unlatching.Closed wind and rain cover purpose is the weather proof Exposure to Sunlight, insulation.Can adopt the breather port mode to solve problems of excessive heat in hot day.4, safety, the way that ordinary bicycle available both feet in danger land or flee from, this totally-enclosed car can not be done like this.The utility model is equipped with each one of the anti-down safety wheel of avidity in the both sides, middle part that are positioned at car for this reason.Two safety wheel are connected as a single entity the built-in torque spring of bearing seat by bearing seat, axle.This safety wheel is suspended from overhead certain height when car travels, under external force, this safety wheel can be done up and down synchronously.In safety wheel mechanism, there is cable wire to be linked to brake, the adjustable height of safety wheel, driving technique unskilled person can directly transfer to safety wheel near the road surface.
Fig. 1 is the construction profile scheme drawing that removes stream line pattern glass steel cage.
Fig. 2 is the plan structure scheme drawing of Fig. 1.
Fig. 3 is the side schematic view that adds with stream line pattern glass-felt plastic cover.
Among the figure: 1, front-wheel.2, Front brake device.3, front wheel spindle.4, direction lever fixed cover.5,6,18,21 is the brake cable fulcrum.7, preceding 48 tooth sprocket wheels down.8, left threading.9, chain.10,90 tooth big gear wheels.11, pedal spindle.12, preceding last 48 tooth hinge wheels.13,20 tooth miniature gearss.14, front wheel spindle.15, front-wheel brake cable.16, sprocket shaft.17, back transmission riding chain.19, safety wheel pull line.20, safety wheel.22, triangular frame.23, rear wheel brake line.24, rear wheel brake device.25, sprocket shaft.26, triangle direction dish.27, right threading.28, preceding speed change small flywheel.29, brake.31, safety wheel bearing seat.32, sit the sleeperette chair support.33, back axle.34, rear wheel.35, support.36,5 grades of gear shift flywheels.37, the after wind canopy is opened attachment point.38, wind and rain cover front portion.39, the wind and rain cover is opened the attacker.40, organism glass form.41, open portion behind the wind and rain cover.42, direction lever.
The utility model exemplary embodiments: step on foot-operated 8,27 and promptly drive big gear wheel 10.Miniature gears 13, the hinge wheel 12, the hinge wheel 12 that also start simultaneously on the pinion shaft 25 reach small flywheel 28 and hinge wheel 7 with power by chain 9, and hinge wheel 7 is passed to trailing wheel 5 gear gearbox flywheels 36 by chain 17 with power, thereby finishes body movement.
When stepping on brake 29, brake cable 15,23 and safety wheel rete cord 19, realization emergency mouth before and after driving.
