Description

Multifunction four-wheel motorcycle

The utility model relate to a kind of four-wheel motor cycle be used for manned lie to sit all can.

With the motor cycle engine is propulsion source, the motor bike that adopts four-wheel to travel on the basis of positive three-wheel.The instability that swings because two-wheeled motorcycle travels; do not protect fluffy to driving accidental impact; for example: the Piaggio that China Foshan produces. NCC GT250 two-wheeled motorcycle; and the motor-tricycle turning loses center of gravity easily; incompatibility sleet sandy soil road surface, for example: the prosperous imperial XL100 wheeled motorcycle that China Hebei produces.

The utility model has improved driving environment, has strengthened comfort of passenger, has strengthened traffic safety and comformability.

The utility model mainly is to be assigned to realize by vehicle frame part, seat part, manoeuvre portion.Front axle with turn to knot connect guide wheel shaft on the interior felling axe fixedly bumper overlap on terminal pad and be fixed on the front-axle beam by U type support, under axle bridge two ends, fix firm plate and connect left-right longeron, the centre adds crossbeam and welds the framework that rolls, and forms two preceding supporting frame, fixedly operator'ies compartment.

Car load is long 240 centimetres, and wide 120 centimetres, high 120 centimetres, about operator's compartment each two, is separated by 40 centimetres in the middle of the door of front and back, the Qianmen dress back mirror that goes, the dress front-view mirror is opened at the back door backward, and the dress tail-gate is upwards opened behind the car.

Front-seat two backrests of operator's compartment lean on mutually with non-two backrest tops, back, 10 centimetres are separated by in bottom, long 40 centimetres, wide 40 centimetres of front-seat seat cushion, with hinge make can turn over forward 180 the degree take flat, high 40 centimetres wide 40 centimetres on backrest, with hinge make can turn over downwards 90 the degree just arrive the seat cushion position, promptly open the seat and just can form long 90 centimetres wide lectulums of 40 centimetres.

Long 40 centimetres wide 40 centimetres of back row's seat cushion, high 60 centimetres wide 40 centimetres on backrest, spinal support is made half folding formula can turn over 90 degree forward and just put the leg position and take flatly, grow a berth of 190 centimetres as will all opening just can form with former and later two seats, one side to seat cushion the place ahead.

Manipulation is formed cross structure by steering handle, steering shaft, deflecting bar, connects left and right sides intermediate rod respectively, and distant arm connects kingpin before and after driving, and the guide wheel shaft fixing by bumper comes steering.

The utility model adopts four tire forces, has increased by 1/4th safety factor, the smoothness that having strengthened turns round travels.As long as the place that front-wheel can pass through, the front and back wheel track overlaps.The trailing wheel rolling resistance reduces, and promptly is convenient to drive improved current power again.With three tracks of positive three-wheel, become two tracks and just reduced by 1/3rd resistance, increased the comformability of road pavement.Use the upset jump seat, open former and later two seats and just can form a berth, the seat dos-, center of gravity in.Turn to the rod member high position in operator platform, chaufeur to be played certain protective action manipulation.

Fig. 1 is that lateral plan, the dashed line view of multifunction four-wheel motorcycle represented the seat, and compare rule is 1: 20 unit centimetre.Fig. 2 handles steering hardware, and compare rule is 1: 10 unit centimetre.1, back handle.2, steering shaft.3, deflecting bar.4, right horizontal drawing.5, kingpin.6, preceding distant arm.7, connect dish on.8, support sleeve.9, connect dish down.10, internal damping device.11, outer bumper.12, right wheel.13, front axle.14, left intermediate rod.The distant arm in 15 backs.16, kingpin.17, connect dish on.18, support sleeve.19, connect dish down.20, internal damping device.21, outer bumper.22, revolver.

Accompanying drawing embodiment: handling steering hardware has Brake lever, a left side that clutch lever is arranged by the right side on (1) handgrip, and handgrip is welded.(2) steering shaft is fixed on by eldest son 90 degree that two has spindle nose that (4) (14) intermediate rod is fastened with the free bearing cover on (3) deflecting bar, (4) (14) bearing fastens (6) (15) sockets (5) (16) in (6) (15) spindle nose cover, (8) (18) are by hub splines, cover is fixed on the lower connecting plate of (9) (19), key is fixed on the upper connecting plate of (7) (17), when vehicle frame is installed the location will be with the key axle to be bumped into fastening bumper top gong mother (10) (11) (20) (21) bumper in (8) (18) the turning sleeve pipe box following has perforation and perforation sieve bar gong mother of place fastening, the axle sleeve of (8) (18) (not drawing among the figure) (13) that link to each other with vehicle frame are connected wheel shaft for front axle two with turning to tie.
