Description

The three-wheel horizontal bicycle

The utility model relates to a kind of vehicle, especially is fit to the vehicle that outing and old man use.

Raising day by day along with people's living standard, demand layer develops from low to high, people are also more and more higher to the requirement of required bicycle, though common two-wheeled cycle (as phoenix bicycle series etc.) is simple in structure, compact, good rigidly, travel more flexible, but also there are many weak points, buttocks, waist, wrist as the people are stressed bigger, and long distance is driven and is easy to produce fatigue; And need certain driving skills; To children, old man etc. or at the snow poor stability that travels on day than the ways face; Analyze from ergonomic, the saddle horse posture can not be given full play to the power of human body, causes the speed of a motor vehicle lower.

For a kind of light, quick, comfortable walking-replacing tool is provided, especially is fit to outing and old man and uses ad hoc this three-wheel of meter horizontal bicycle.

This utility model product mainly is made of five major parts, referring to accompanying drawing.

One, vehicle frame, seat are shown in accompanying drawing 1,2, and vehicle frame [14] is a bathtub formula curved beam structure, designs by ergonomic, curves with metal tube, and seat [5] is used than thin metal pipe and curved, the structure of sofa-type, and shape meets the ergonomic requirement.Be welded with seat front frame [13], after poppet [10], back vent plate [22], front-wheel crossbeam deck [30] on the vehicle frame, supporting links to each other with the seat front frame with bolt before the seat, back supporting links to each other by pin with sleeve pipe [11] on sleeve pipe [12] and the seat after poppet, supporting place respectively has position, some holes before and after the seat, can make seat do the adjustment of front and back, backrest inclination degree, to be fit to different height human needs.

Two, running part adopts the chain-driving of band transmission system shown in accompanying drawing 1,2.Floral disc [2] and pedal [1] are in the foremost of car, adopt the biplate floral disc of normal tape backplate, the floral disc axle sleeve is welded on the vehicle frame, flywheel and change-speed box [7] are identical with common variable speed bicycle, collide in order to prevent chain [19] and vehicle frame, seat etc., between from the floral disc to the flywheel, be provided with two pressing sprockets [16], [17], pressing sprocket adopts antifriction-bearing box to link to each other with the pressing sprocket axle, the pressing sprocket axle is fixed by bolts on the pressing sprocket frame, one of them pressing sprocket frame is welded on below the seat front frame, and another pressing sprocket frame is welded on the front portion of vehicle frame.Change transmission by speed regulation device and recently control the speed of a motor vehicle.Running part also can adopt secondary chain-driving or gear--the transmission of chain secondary.

The secondary chain-driving as shown in Figure 4, flywheel, change-speed box and floral disc pedal are the same, the cancellation pressing sprocket increases a tween drive shaft [36], first order chain-driving [33] is from the floral disc to the tween drive shaft, second stage chain-driving [34] is from the tween drive shaft to the flywheel, gear--chain-driving as shown in Figure 5, there is not floral disc, the first order [36] adopts Bevel Gear Drive, power turns first pair of conical gear of beam warp by pin and passes to transmission shaft, passes to tween drive shaft [33] through second pair of conical gear again, and chain-driving [39] is adopted in the second stage from the tween drive shaft to the flywheel.

Three, front-wheel and knuckle section are shown in accompanying drawing 1,2, and front-wheel is two 12 "-22 " general bicycle quick [15].Knuckle section adopts double trapezoid steering hardware or Ackerman steering mechanism, and wushu deflecting bar [3] adopts the preceding bearing arrangement of ordinary bicycle with deflecting bar axle sleeve [18]; The deflecting bar axle sleeve is welded on the connecting panel [29], and connecting panel is fixed by bolts on the crossbeam [23].Front-wheel is contained on the front wheel spindle [24], front wheel spindle and steering yoke bolt adopt screw thread or cylinder to be connected, bearing arrangement, the steering yoke bolt cover is welded on the crossbeam before steering yoke bolt [27] and steering yoke bolt cover [28] the employing bicycle, and crossbeam and vehicle frame are fixed with screw thread by connecting panel.Tie rod arm [25] forms certain included angle and fixing by circumferential locate mode (as square hole) and steering yoke bolt, central rocking arm [31] on the deflecting bar is used the articulation hole bolted connection with tie rod arm by length-adjustable pull bar [26], and braking rim brake [20] and speed change regulating handle device [21] are housed on the handlebar.For the ease of seat up and down, deflecting bar can fall forward, deflecting bar was divided into two-section for this reason, adopted cassette to connect between the two-section, with eccentric pin [32] locking.

Four, trailing wheel part adopts general three or five or six grades of speed changes 24 as shown in Figure 1 "-28 " rear wheel assembly [8], by after again plate [22] be fixed by bolts on the vehicle frame.

Five, brake portion as shown in Figure 1.Adopt general cable brake formula rim brake, the trailing wheel braking.Rim brake [20] is contained on the handlebar, and the brake rubber block drg is contained on the vehicle frame.

Can set up article basket [6] in addition, sun and rain shading awning [4].As shown in Figure 1.

This three-wheel horizontal bicycle changes riding and is the sitting posture of lying, and changing two-wheeled is three-wheel, thereby has overcome the shortcoming of above-mentioned two-wheeled cycle, and has certain new function.The utility model product is compared with ordinary bicycle, has advantages such as comfortable, laborsaving, that speed is fast, and F-Zero can reach 40 kilometers/hour, drives easily, and safety is better.The most parts of this car, consumable accessory are general with the part on the common two-wheeled cycle, have make simply, use, advantage such as easy to maintenance.
