Description

Employment instrument motor bike

Technical field:

The utility model relates to a kind of employment instrument motor bike, and this motor bike is formed the two patterns that drive of a four-wheel, can sit people or shipping goods, belongs to the field of motor bike.

Technical background:

Existing two-wheeled or motor-tricycle, poor stability, safety factor is low, often cause traffic accident, cause wounded or disabled consequence also a lot, when the speed of a motor vehicle is higher, be difficult to emergency braking,, all can not compare with the self-propelled vehicle of four-wheel because of emergency braking causes defective steering stabilizer degree and danger often, therefore a lot of two-wheeled motor vehicles often rolls, bumping does not in motion have the efficient buffer device yet, therefore causes wounded or disabled accident, and night, flame-out parking often scraped or damage on dark road, the different again automobiles of the steering mode of motor bike have also limited the application of motor bike.

Summary of the invention:

The purpose of this utility model is that a kind of employment instrument motor bike will be provided, it has four wheels, comparatively steady, be easy to drive, its frame-type vehicle frame joins by support arm and wheel, and shock absorber is housed, drive wheels is that sprocket chain strip transmission mechanism and difference device join, and this motor bike has the hand shift system, and single gas heating system and steering swivel system disappear, correspondingly the characteristics of motor bike are combined with the advantage of automobile, enlarged the range of use of motor bike.

By Fig. 1 combined framework type vehicle frame (1) is to be welded into steel pipe, by front and rear support arm 2, be connected with 2 trailing wheels (25) with 2 front-wheels (24) through wheel shaft (8), bumper (3) cooperates with support arm (2), realized that four-wheel is from each independently suspension and shock mitigation system, chain (4) connects sprocket wheel (5) and (26), be connected with sprocket wheel (28) with chain (29) again with another sprocket wheel (27) of sprocket coaxiality, the sprocket wheel (30) coaxial with sprocket wheel (28) is connected with sprocket wheel (32) with chain (31) again, sprocket wheel (32), 30,28,27 and chain (29) (31) form a secondary transmission and reverse gearwheel case (6), difference device (7) joins with hind axle (8), front-wheel (24) trailing wheel (25) is connected and fixed with the annex of vehicle frame (1), forms a two driving system that drives thus.

On front-wheel (24) axle brake wheel (9) is housed, later brake cross shaft (48) affects the braking shoes.Braking flexible cord (10) is connected by annex on the vehicle frame with brake pedal (11), constitutes consistent formula four-wheel braking system.Be provided with brake pedal (11) location, realize the device of vehicle parking maintenance.

By Fig. 1,2, the connecting rod of telescopic bearing circle (12) is connected with turning to conversion servo-unit (13), joins with direction machine (14) again.

By Fig. 3, sprocket wheel (5) the (see figure 1) chain drive-belt (4) on motor (22) axle is delivered to power the sprocket wheel (26) of back axle by chain (47).By figure (4), (5), the bearing circle of steering swivel system (12) connects an expansion link (37), connect a conversion servo-unit (13) again, just the expansion link lower end has the gear on a gear and the connecting rod (33) to mesh in gear case, this two gear constitutes a conversion servo-unit (not representing gear among the figure), 33 times termination directions of connecting rod machine (14), there is the tooth bar engagement (not representing rack-and-gear among the figure) in a gear and the direction machine (14) connecting rod (33) lower end, the spindle nose connection one at tooth bar two ends turns to the adjusting yoke (15) with preceding speed, pull bar (15) outer end has a steering ball end (34) to be connected with vertical shaft rocking arm (35), and rocking arm (35) other end connects a vertical shaft (36).

By Fig. 6,7, the hand gear shifting lever of hand shift system (20) is connected with conversion upper rocker arm (39) with gear shift transverse axis (38) warp beam sleeve (43), conversion upper rocker arm (39), be connected by attaching parts (40) with another conversion lower shake-changing arm (41), the front end of this lower shake-changing arm (41) is connected with the shift shaft (42) of driving engine (21).

By Fig. 1, the noise reduction freeing pipe is made structure of two layers, internal layer waste discharge gas, outer water filling, rely on the waste heat that absorbs internal layer waste gas to make water be subjected to thermal evaporation, discharge the radiator (representing the figure) that enters in the car storehouse from steam (vapor) outlet (44), after the heat radiation, water condensation sinks to flowing back to the freeing pipe skin through water return outlet (45) again, forms the heating system of heat cycles, power-transfer clutch flexible cord (16) one ends are connected with driving engine (21), another termination clutch pedal (17), throttle flexible cord (18) one termination carburettor (not shown) connect, another termination Das Gaspedal (19), exhaust fan (23) is loaded on driving engine (21) front end, and driving engine is carried out force-air cooling.

The peripheral buffering of car was protected thick stick and inflation or on-inflatable rubber impact bag and illumination 5 minutes, and is effectively luminous more than 10 hours, is not reflective, and the bright caution configuration at night of international third generation on-radiation is because of changing with the car profile, so do not illustrate.
