Description
The utility model relates to the motor-tricycle of using in a kind of automotive field, a kind of more precisely superminiature three-wheel passenger and freight transportation car or car for disabled persons.
The existing motor-tricycle that makes things convenient for all is equipped with a driving engine, by power-transfer clutch, driving device, drives a trailing wheel as drive wheel, causes vehicle influenced by an additional deflecting torque, thereby reduces vehicle handling and stability.In addition, a trailing wheel is only arranged, adhesive ability is reduced, go up a slope and skid easily as drive wheel.Existing motor-tricycle all is provided with diff in back axle, no matter turning or make pure rolling when rough road travels with two drive wheels about guaranteeing, this not only makes complex structure, from great, and makes the cargo floor height be difficult to reduce.All use dependent suspension in addition, directly have influence on the riding comfort of vehicle.After the driving engine et out of order was shut down, vehicle just can not travel.
The utility model is exactly for overcoming above deficiency, and provide a kind of twin-engined motor-tricycle that makes things convenient for, its main purpose is: adopt two driving engines, be installed in two outsides about vehicle frame respectively, connect with separately self-acting clutch and active Pulley, drive transmission gearbox and drive wheel semiaxis by drive belt and drive separately two rear drive sprockets, to improve the dynamic property and the road-holding property of vehicle.Save traditional diff, reduce the vehicle's center of gravity height, the body contour height is reduced greatly, thus the moulding that makes the home-use car of superminiature wide, be tending towards coordinating at high proportion, create a new road for the superminiature home vehicle enters society.
The utility model is achieved in that twin-engined motor-tricycles, comprise driving engine, vehicle frame, chain stay, it is characterized in that: two driving engines are installed in two outsides about the vehicle frame middle part respectively, respectively with separately self-acting clutch and initiatively Pulley connect, clutch plate connects with transmission gearbox and drive wheel semiaxis, drives transmission gearbox and drive wheel semiaxis by drive belt and drives separately two rear drive sprockets.The vehicle bridge that does not have in the middle of two rear drive sprockets to connect connects, and has saved diff.On two base chambers hinged support is set respectively, hinged with bearing pin and vehicle frame, two combination rocker structures constitute independent suspension naturally about formation.
Below in conjunction with accompanying drawing groundwork of the present utility model is described in further detail:
The twin-engined motor-tricycle scheme drawings of Fig. 1 a, b
Foreign steamer force analysis figure in when Fig. 2, turning
Wherein:
1-driving engine 2-vehicle frame 3-bearing pin
4-drive belt 5-chain stay 6-drive wheel semiaxis
7-transmission gearbox 8-is from movable strap disc
9-self-acting clutch and active Pulley 10-drive wheel
The concrete measure that the utility model adopted is: two driving engines are installed in two outsides about the vehicle frame middle part respectively, are handled the synchronous unlatching of two throttle gates or are closed by a twist grip throttle control.Self-acting clutch and active Pulley are an integral body, drive clutch plate ［ 8 ］ by drive belt ［ 4 ］, form the belt type adjustable speed drive structure.When engine speed during greater than 1500 rev/mins, the self-acting clutch of crankshaft end is engaged, the moment of torsion of driving engine just drives from movable strap disc ［ 8 ］ through drive belt ［ 4 ］, drives drive wheel semiaxis ［ 6 ］ through transmission gearbox ［ 7 ］ and orders about drive wheel ［ 10 ］ and rotate.The structure of vehicle frame the right and left driving engine connects and working process is same.
Because two driving engines are not cascaded, thereby allow with different rotation speed operation.If behind the engine shutdown on the left side, the driving engine on the right still produces tractive force, and the drive wheel on the left side promptly becomes flower wheel.When this car is made straight-line travelling on straight road surface; if the driving engine developed power is different, one side the little one side of left and right wheels power can be by big driving, and left and right wheels speed difference can not appear; but the degree that drives is more much smaller than shutting down on one side, so can make left and right wheels run-in synchronism.Because two drive wheels are driven by separately driving engine respectively, therefore, when the tyre skidding of one side, the another side wheel still can produce propulsive effort as usual, as automobile the antiskid diff is housed, thereby has improved the cross-country traveling ability of vehicle.
Foreign steamer force analysis in when Fig. 2 turns is because the no stage gear ratio of the right and left drive belt can change because of the difference of two wheel drags, so can allow two drive wheels to rotate with different speed.Because work as Ackermann steer angle, because the deflection of vehicle frame ［ 2 ］ produces the steering torque in horizontal surface by chain stay ［ 5 ］ to two drive wheel semiaxis ［ 6 ］.Under the effect of this moment, drive wheel semiaxis ［ 6 ］ is just internal, foreign steamer produces an equal and opposite in direction, the additional levels directed force F that direction is opposite
JBecause the F of interior wheel (left figure)
JOpposite with vehicle heading, must play the effect that wheel rotates in slowing down, i.e. F
JDrag wheel backward, produce F
J.Y additional resistance square, and (because of its direction opposite with drive torque Mt).If this moment, moment of torsion, the rotating speed of two driving engines still remained unchanged,,, slow down thereby take turns in making just the transmitting ratio of its stepless speed changing mechanism can correspondingly increase because interior wheel dropping moment increases.In addition, because interior wheel dropping moment increases, the external load of driving engine also increases, even converter speed ratio does not change, therefore the rotating speed of driving engine also can decrease, thus the corresponding deceleration of wheel in making.In like manner, because foreign steamer F
JIdentical with vehicle heading, accelerate the effect that foreign steamer rotates so must play.Vehicle wheel rotational speed like this one increases one and subtracts, and foreign steamer is made pure rolling with different rotating speeds in just guaranteeing when turning to, and can not go out phenomenon integral type axletree like that in wheel spike, the outer skidding phenomenon of dragging.
The vehicle bridge that does not have in the middle of two rear drive sprockets of the present utility model to connect connects, thereby saved diff, cargo floor is sunk down into below the wheel center, vehicle's center of gravity is reduced greatly, improve stability, traveling comfort, the safety of motorcycle driving, height of contour that the more important thing is vehicle body reduces greatly, thereby makes the moulding of the home-use car of superminiature be tending towards coordinating on wide high proportion, creates a new road for the superminiature home vehicle enters society.
The utility model is combined into a rigid unitary to driving engine ［ 1 ］, chain stay ［ 5 ］, transmission gearbox ［ 7 ］ and drive wheel ［ 10 ］, hinged support is set on base chamber, with hinge ［ 3 ］ and vehicle frame pin joint, two combination rocker structures about formation, it teeters along with the vibration of bumper, because the vehicle bridge that does not have between two drive wheels to connect connects, is independent of each other during the left and right sidesing driving wheel bob, naturally formed independent suspension by trailing arms, structure is very simple.
Compared with the prior art, the utility model has the advantage of:
1, employing is twin-engined, has improved dynamic property and reliability. After an engine hindered shutdown for some reason, another still can make Vehicle Driving Cycle, unlikelyly cast anchor halfway.
2, save differential mechanism, reduced vehicle's center of gravity height and vehicle body height overall.
3, constitute independent suspension simply, improved ride comfort.
