Description

Inverse trailing multi-function tricycle

The utility model relates to a kind of improved three-wheel vehicle, particularly a kind of later-model towed multi-functional three-wheel vehicle that falls.

Manned or cargo-carrying three-wheel vehicle in the prior art, its structure all are a front-wheel and two trailing wheels, and in the process of moving, the rider can't look after goods or person's (child particularly especially needs to look after at any time) by bus after one's death well.And, the three-wheel vehicle of this structure, stability of travelling and traveling comfort are all relatively poor, overturn easily when turning to, and the beginner need grasp technology by bike for a long time.

The purpose of this utility model is to overcome the defective of prior art, provides a kind of simple in structure, multiple functional, easy to use fall towed three-wheel vehicle, it adopts two front-wheels and a trailing wheel, has steering hardware on the front-wheel chassis, can finish handling maneuver at an easy rate.

The purpose of this utility model is achieved in that a kind of towed multi-functional three-wheel vehicle that falls, by vehicle frame, handlebar, and vehicle seat, the compartment, brake, chain drive, foresteerage gear, preceding wheeling support, two front-wheels and a trailing wheel are formed.Described foresteerage gear by with integrally formed chassis, compartment, the slideway on the chassis is fixed on pipe in the turning center on the chassis, with the integrally formed spindle arm of vehicle frame, the turning center outer tube and the travelling arm that are fixed on the spindle arm constitute.One end of described travelling arm is captiveed joint with spindle arm, and the other end is connected with a pulley or slide block, slides in the circular arc slideway that this pulley or slide block form on the chassis.In the described turning center between pipe and the turning center outer tube for being connected rotationally, as an antifriction-bearing box is set.The two ends of described circular arc slideway are provided with spacing rubber block.Described handlebar is captiveed joint with the compartment, and rim brake handle and bicycle bell are housed on the described handlebar, and described compartment is equipped with seat, and hood can be installed in the top, compartment.Can the installation foot brake foot plate below between described compartment and the vehicle seat.

Of the present utility modelly fall towed multi-functional three-wheel vehicle and compared with prior art have simple in structure, good manufacturability, multiple functional, widely applicable advantage.Foresteerage gear and handlebar attended operation turn to nimbly and freely, are difficult for overturning.The compartment is located at front-wheel, and the rider can look after goods or person by bus easily.The general part of full car accounts for more than 60%, and interchangeability is good, and is easy to maintenance.

Below in conjunction with accompanying drawing, most preferred embodiment of the present utility model is described in further detail:

Fig. 1 is that the utility model falls the structural representation of towed multi-functional three-wheel vehicle;

Fig. 2 is the structural representation of foresteerage gear of the present utility model.The direction of this figure is for to look up under the compartment.

Among the figure: vehicle frame 1, vehicle seat 2, back vehicle frame 3, trailing wheel 4, chain drive 5, brake 6, travelling arm 7, preceding wheeling support 8, front-wheel 9, spindle arm 10, turning center outer tube 11, front apron (or stretcher) 12, compartment 13, chassis 18, rim brake handle 14, handlebar (handrail) 15, bicycle bell 16, circular arc slideway 17, chassis 18, pulley 19, pipe 21 in the spacing rubber block 20, turning center, foresteerage gear 22.

Referring to attached Fig. 1 and 2, a kind ofly fall towed multi-functional three-wheel vehicle, by vehicle frame 1, handlebar 15, vehicle seat 2, compartment 13, brake 6, chain drive 5, foresteerage gear 22,8, two front-wheels 9 of preceding wheeling support and a composition such as trailing wheel 4.Described foresteerage gear by with integrally formed chassis 18, compartment, circular arc slideway 17 on the chassis 18, be fixed on pipe 21 in the turning center on the chassis, be actually the part of vehicle frame with vehicle frame 1 integrally formed this arm of spindle arm 10(), the turning center outer tube 11 and the travelling arm 7 that are fixed on the spindle arm 10 constitute.One end of described travelling arm 7 is captiveed joint with spindle arm 10, for example welding.The other end is fixedly connected with a pulley or slide block 19, slides in the circular arc slideway of this pulley 19 on chassis 18.Connect rotationally between pipe 21 and the turning center outer tube 11 in the described turning center, an antifriction-bearing box (not shown) can be set between them.The two ends of described circular arc slideway 17 are provided with spacing rubber block 20, in case limited slip wheel or slide block 19 are deviate from from slideway 17.Rim brake handle 14 and bicycle bell 16 are housed on the described handlebar 15.In the described compartment 13 seat can be housed, can also load onto lid during loading, front apron 12 is equipped with in the place ahead in compartment 13, is connected with the chassis by extension spring, as sitting man-hour in the compartment, can also put down this front apron 12, and this moment, front apron 12 just became stretcher.Hood can be installed in 13 tops, compartment, and seeking shelter from wind and rain, but the installation of hood can not be blocked cyclist's sight line.A backpedalling brake pedal (not shown) can be installed in below between compartment 13 and the vehicle seat 2, to be used with rim brake.

Of the present utility model to fall towed multi-functional three-wheel vehicle the same with ordinary bicycle, adopts chain drive, the back-wheel drive front-wheel, and load acts on the front-wheel, therefore is referred to as towed.The cyclist is sitting in walking vehicle handle on the vehicle seat, and foresteerage gear and handlebar attended operation turn to steadily flexibly, and the degreeof turn of car can reach 180 °
