Abstract

The utility model relates to a reverse motor tricycle. The problems of poor performance of anti-vibration waves, unstable traveling and low mechanical efficiency of a present positive three-wheel type and a deflective three-wheel type motorcycles are solved. The utility model is characterized in that two steering wheels are arranged in the front part of the motor tricycle. A drive wheel is arranged in the back part of the motor tricycle. Front wheels are hinged on a motor tricycle frame by using a hanging bracket with a wheel bracket. Back wheels are arranged on the output shaft of an engine which is hinged on the motor tricycle frame through a back rock arm and a spring damper. The reverse motor tricycle can be used as a common motorcycle.

Description

Reverse motor tricycle

The utility model relates to a kind of motor bike, particularly a kind of Reverse motor tricycle.

Existing motor-tricycle has two kinds of patterns, and a kind of is positive three-wheel pattern, and promptly there is a wheel front of car, and there are two wheels the back, and three wheels are equicrural triangle and distribute; A kind of is inclined to one side three-wheel pattern, i.e. wheel in the front of car, and two wheels in back, three rectangular triangles of wheel distribute.The motorcycle front-wheel of these two kinds of patterns all is a wheel flutter, and trailing wheel is a drive wheel, and their engine installation drives two trailing wheels in the front portion of car through chain-driving or shaft transmission system.There are 2 deficiencies in they: the firstth, and driving engine causes mechanical efficiency to reduce through chain or axle driving trailing wheel; The secondth, the wheel in the front of car, make bear travel in the ability of top wave impact, cause and travel not steadily, even may cause overturning.

It is strong that the purpose of this utility model designs a kind of top wave impact ability of bearing exactly, the motor bike that mechanism efficiency is high.

The utility model is achieved in that this motor bike still has vehicle frame, compartment, oil circuit and electric apparatus, brake equipment, its difference is: the anterior the right and left at car respectively has a wheel, they are passive wheel flutters, in the middle of the rear portion of car a wheel is arranged, it is a drive wheel.Two front vehicle wheels respectively are hinged on the vehicle frame with a suspension that has wheel stand.Trailing wheel is installed on the output shaft of driving engine.Articulated rear arm and jounce bumper between driving engine and vehicle frame.For making wheel steering, a connecting lever is respectively arranged on the wheel stand of two front-wheels, articulated lateral connecting rod between two connecting levers, also has a spindle arm on one of them wheel stand, articulated connecting rod between spindle arm and the swing arm that affected by steering wheel shaft turns to synchronously thereby just can drive two front-wheels when steering wheel rotation.

Its structure of suspension that has wheel stand of the present utility model is: axletree is contained in the lateral aperture of wheel stand, the vertical shaft on the top of wheel stand is contained in the upright hole of rocking arm one end, the other end at rocking arm, it is hinged on the vehicle frame also articulated jounce bumper between rocking arm and vehicle frame with the bearing pin that passes horizontal endoporus on the rocking arm.

Because this motor bike has two front-wheels, each front-wheel all is installed on the suspension, between suspension and vehicle frame jounce bumper is housed, and suspension can be around swinging up and down with the relative vehicle frame of bearing pin of vehicle frame hinged place, so its anti-top wave impact ability and the stationarity of travelling are better than the motor bike of the wheel in front greatly.Its trailing wheel and driving engine also are to adopt suspension type to be hinged on the vehicle frame, and resistance to shock is also very good.This motor cycle engine is contained in the rear portion of car, and trailing wheel just is contained on the output shaft of driving engine, therebetween need not any transmission device, therefore just there are not mechanical loss, mechanical efficiency height.

Below in conjunction with accompanying drawing the utility model is described in detail.

Anterior the right and left at car has

wheel

2 and 3 as can be seen from Fig. 1 and Fig. 2, and they are passive wheel flutters, in the middle of the rear portion of car wheel 18 is arranged, and it is a drive wheel.

Wheel

2 and 3 is contained in respectively on

suspension

4 and 5 as can be seen from Figure 2, and

suspension

4 and 5 is hinged on the right and left of vehicle frame 1 front portion respectively with bearing pin 6 and 7.Suspension 4 is identical with 5 structure, and existing is the example explanation with right suspension 5.Fig. 3 and Fig. 4 have represented the structure of right suspension.The connection of wheel 3 usefulness splines is contained on the right axletree 9, and right axletree 9 usefulness two dish bearings 8 are contained in the horizontal endoporus of right wheel stand 11, and axle head is all fixed with nut.Right vertical shaft 13 is arranged at the top of right wheel stand 11, and right vertical shaft 13 usefulness two dish bearings 14 are contained in the upright hole of right rocking arm 15, and axle head is fixed with nut.Outside at the upright hole wall of right rocking arm has hangers 17.One end of jounce bumper 16 just is hinged on the hangers 17, and the other end is hinged on the vehicle frame 1.The other end of right rocking arm 15 has a lateral aperture, and bearing pin 7 passes this lateral aperture and right rocking arm 15 is hinged on the vehicle frame 1.When car travels at scraggly road, but except that jounce bumper 16 up-down vibration, whole right suspension 5 is being with wheel 3 to swing up and down around bearing pin 7 relative vehicle frames 1, has so just improved the stationarity of car.

From Fig. 2 and Fig. 5 as can be seen, rear wheel 18 usefulness pattern chains connect and are contained on the output shaft of driving engine 17.Articulated rear arm 16 and jounce bumper 19 between driving engine 17 and the vehicle frame 1.This underslung structure has guaranteed that when being vibrated driving engine 17 can swing up and down by relative vehicle frame 1 with rear wheel 18.

From Fig. 2 Fig. 6 as can be seen, the structure of steering hardware.On the right wheel stand 11 connecting lever 21 is arranged, a connecting lever 22 and a spindle arm 24 are arranged on the left wheel support 10.Articulated connecting rod 25 between spindle arm 24 and the swing arm 23, articulated lateral connecting rod 26 between connecting lever 22 and the connecting lever 21.Between steering wheel shaft 27 and the swing arm 23 universal coupling 28 is housed.When steering wheel rotation, but left wheel 2 is rotated around left vertical shaft 12 with regard to direction of passage dish axle 27-swing arm 23-connecting rod 25-spindle arm 24.Simultaneously, spurred right wheel 3 by connecting lever 22-lateral connecting rod 26-connecting lever 21 and rotate around right vertical shaft 13, this has just reached two

front vehicle wheels

2 and 3 is turned to synchronously.
