Description

Super light driving and steering device for three wheel motor car

The utility model relates to the driving and the steering hardware of the preceding bikini motor-tricycle of driving and steering hardware, particularly engine petrol of the preceding bikini of a kind of ICE-powered (positive three-wheel) three-wheel vehicle.

Motor-tricycle, because its structure is simpler, turn radius is little, and the influence of various countries' traffic law, 50-sixties end once developed at state Ceng Xingwang such as the U.S., Japan, Italy and Germany and Italy federal states, wherein with " big sending out ", " Mazda " of Japan, the type trades mark such as " RUNABOUT " of AM General company is more representative.Because the rear driving system diff exists and the engine installation position is preposition, except that cost near the four-wheeled, also higher apart from ground because of freight house, be easy to turning over during high speed steering.

For addressing this problem, U.S. TRIVAN proposes the first two and takes turns back one scheme of taking turns, though its freight house is high lower apart from ground, moves after the center of gravity during heavy duty, and safety is still bad.

The purpose of this utility model be propose a kind ofly to obtain that center of gravity is low, the turning to and driver train of motor-tricycle simple in structure.

It is achieved in that the front-wheel with three-wheel vehicle is arranged on the vehicle body longitudinal axis, and two trailing wheels then wait and leave longitudinal axis longways, and two trailing wheels connect with the hitch and the vehicle body of known band telescopic shock absorber traveller swing arm type or other known forms respectively.Wheel is bearing on the lateral shaft with the wheel hub inner core-body of traveller sports association knot by bearing, also has another root arm on horizontal axletree next door, and the arm end has a hinge, and hinge connects by a pull bar and another wheel pull bar, again with car before end turning mechanism output swing arm connection.When rotating steering wheel, two-wheeled then turns over respective angles to the left and right and realizes turning to of car.

For avoiding descending because of the back interconnected intermediate rod of two-wheeled hinders the freight house bottom, a kind of alternative plan is that the steering hardware output arm is increased by an arm again in 180 degree directions, makes output shaft turn to down same, and two output arm sense of motions are opposite.At two output arm ends one hinge is arranged all, the pull bar that saves length with two Ke Yi Tone connects the rear-axle steering arm, and when making the steering wheel left-right rotation, back two-wheeled gets final product to the corresponding rotation of required direction.

Front-wheel is by common bearing--and axle bolt is separately fixed on a shaft-like beam and the strip gearbox body in parallel, shaft-like beam and gearbox body one end are hinged on vehicle frame, form the rocker structure, suitably apart from also having a pair of cartridge type double acting bumper to connect to ground outward, front-wheel can swing up and down under road surface or vehicle body impact apart from hinged point.

The common automatic transmission with hydraulic torque converter of device or other change-speed box in the change speed gear box, the direct and front-wheel connection of gearbox output also can be passed through chain, belt pulley and wheel and connect.The gear box input end is with the prolongation axle connection of methods such as elastic coupling, spline with driving engine.Axle is outer to have tubular cover that driving engine and change speed gear box are linked to be an integral body, and driving engine is positioned at the relative gearbox body opposite side of front-wheel, with the moment of balance change speed gear box to front-wheel.Engine cylinder is got vertical or horizontal according to common mode, also can cylinder axis and the oblique placement between 15 degree-30 degree of horizon angle, and when utilizing the natural wind heat radiation, the cylinder head court direction of advancing makes the air-flow useful effect in radiating gill.

Because gearbox body and front-wheel connect, driving engine and change speed gear box are an integral body, therefore during shimmy of front wheels, engine block and gearbox body be swing simultaneously also, because engine crankshaft is positioned at gearbox body and shaft-like beam and the hinged place of vehicle body, therefore as long as carburettor is arranged near the crankcase, be fully can normal operation.

Because change-speed box is positioned at the front-wheel side, can not use the direct control mode of engine speed changer under the common seat, (automatic transmission with hydraulic torque converter makes an exception certainly) should be at the speed-changing lever end, fixing a roots and tops has the arm of direction hinge (spherical hinge, rubber bearing hinge) or common directed hinge, hinge connects a pull bar, make the pull bar axis parallel or be parallel to the front-wheel axle center as far as possible--under the condition of hinged some axle center on line of front-wheel rocker and vehicle body, guide easy to handle position into.

The steering unit of throttle, clutch, preceding braking then can use two, the existing structure of motor-tricycle.

Another kind of alternative front-wheel suspension solutions is that rocker is served as separately by gearbox body, and front wheel spindle is encorbelmented at change speed gear box one end, and bumper can be kept to one.

It is pointed out that when using two bar beam rocker and also can bar beam and gearbox body be linked with a contact beam.The hinged bumper in stress equilibrium position in the contact beam.Move to the back lower place when bumper is compressed, facing the wind highly to reduce vehicle body.

The utility model is because use the front engine front drive mode, omitted diff and semiaxis, axle housing, coupler structure very simple outside, also can more freely reduce the car load height of gravitational center.Simultaneously, driving engine, gearbox body are positioned at front-wheel two sides, not only utilize natural air cooled convenience, vehicle body is positive facing the wind height can near or similar in appearance to the tire height.

Another kind of alternative plan is: rocker, telescopic shock absorber that the gearbox body and the shaft-like beam on brake drum of front wheel right hand and left hand right side constitutes is hinged on " door " shape framework, the rigidity of framework should be enough to support whole front-wheel and driving engine--transmission system, " door " shape framework is by two planes-axially the double acting bearing is bearing on the vehicle body, also has an end that the arm of hinge is arranged on " door " shape truck transom.The steering box output arm is by a bar or directly connection with it, the left-right rotation steering wheel can make " door " shape framework and front-wheel, driving engine, change-speed box left-right rotation turn to realizing, at this moment handle throttle, power-transfer clutch, change-speed box, drg all need use common flexible steel wire rope--casing bit.

Below in conjunction with accompanying drawing the utility model is further elaborated.
