Description
The utility model relates to a kind of three-wheel vehicle.
Existing three-wheel vehicle, no matter be manual tricycle, or three wheeled motor car or electro-tricycle, all form by front vehicle frame and back vehicle frame, wherein front vehicle frame includes bottom girder, and the bottom girder front end upwards is connected with standpipe, and the standpipe upper end is connected with seat cushion, the bottom girder front end is connected with preceding cant beam to the front upper place simultaneously, and it is used for connecting the front-wheel support of three-wheel vehicle.Then vehicle frame is a framework, and both sides are used for connecting two trailing wheels, and top is used for installing the railway carriage of three-wheel vehicle.Captive joint with the underframe of back vehicle frame usually in the bottom girder rear end of front vehicle frame.It is bad to meet the road surface like this, or rear flank wheel runs into when exceeding the ground-surface obstacle, can make the back vehicle frame to a side perk, makes three-wheel vehicle be prone to the rollover accident.Because captiveing joint of three-wheel vehicle front vehicle frame and back vehicle frame makes that then the turn radius of three-wheel vehicle is big, and the turning very flexible also is prone to the rollover accident when meeting sharply turning, safety is relatively poor simultaneously.
The purpose of this utility model is exactly in order to address the above problem, and provides a kind of stability, alerting ability and safety good Tricycle with the function of preventing it from side turning over.
Technical solution of the present utility model is as follows:
A kind of Tricycle with the function of preventing it from side turning over, it includes the front vehicle frame and the back vehicle frame of three-wheel vehicle, and wherein front vehicle frame is made of bottom girder, standpipe and preceding cant beam, the standpipe upper end is connected with seat cushion, the termination of preceding cant beam links to each other with front-wheel support, and front-wheel support upwards is connected with handlebar, is connected with front-wheel downwards; The back vehicle frame of three-wheel vehicle is a frame body, its both sides are used for connecting trailing wheel, its middle part is used for installing the railway carriage of three-wheel vehicle, it is characterized in that it is fixed beam that trailing wheel carriage frame support body bottom connects the middle wheel shaft of two trailing wheels, the bottom girder rear end of front vehicle frame just is movably connected in the middle part of this fixed beam, and both sides, back carriage frame support body top all connect forward to stretch connecting rod, and two connecting rods are connected with the standpipe correspondence position of front vehicle frame by elastic body separately, they is flexibly connected be one.
The utility model is movably connected the bottom girder and the back vehicle frame of the front vehicle frame of three-wheel vehicle, and also link to each other between front vehicle frame and the back vehicle frame by elastic body, so have relatively independent stability and alerting ability between the forward and backward vehicle frame of three-wheel vehicle, when trailing wheel is met Uneven road or obstacle, when making back vehicle frame generation perk phenomenon, then since front vehicle frame for flexibly connecting, so not subsequently vehicle frame phenomenon appears turning on one's side together, safety improves greatly.Because the movable connection structure of front vehicle frame makes that the turn radius of three-wheel vehicle is little, and alerting ability is good, can not turn on one's side when meeting sharply turning simultaneously yet, make the performance of three-wheel vehicle bring up to a new height.
Fig. 1 is a monnolithic case scheme drawing of the present utility model;
Fig. 2 is a forward and backward vehicle frame scheme drawing of the present utility model.
(Fig. 1, the 2nd is an example with the electro-tricycle as Fig. 1,2, other three-wheel vehicle is all identical), the utility model includes the front vehicle frame 1 and the back vehicle frame 2 of three-wheel vehicle, wherein front vehicle frame 1 is made of bottom girder 3, standpipe 4 and preceding cant beam 5, standpipe 4 upper ends are connected with seat cushion 6, the termination of preceding cant beam 5 links to each other with front-wheel support 7, and front-wheel support 7 upwards is connected with handlebar 8, is connected with front-wheel 9 downwards.The back vehicle frame 2 of three-wheel vehicle is a frame body, its both sides are used for connecting trailing wheel 10, its middle part is used for installing the railway carriage 11 of three-wheel vehicle, characteristics of the present utility model are trailing wheel vehicle frame 2 frame body bottoms to be connected two trailing wheels, 10 middle wheel shafts change fixed beam 12 into, bottom girder 3 rear ends of front vehicle frame 1 just are movably connected in the middle part of this fixed beam 12, and both sides, back vehicle frame 2 frame body top all connect forward to stretch connecting rod 13, two connecting rods 13 are connected with standpipe 4 correspondence positions of front vehicle frame 1 by elastic body 14 separately, they are flexibly connected be one.In order to guarantee the stability of three-wheel vehicle, usually standpipe 4 rear sides in front vehicle frame 1 are provided with arc support bend pipe 15, its upper end links to each other with standpipe 4 upper ends, its lower end links to each other with bottom girder 3 middle parts, at this moment, two of back vehicle frame 2 connect the connecting rod stretched 13 forward and just link to each other with the middle part of support bend pipe 15 by two elastic bodys 14.Elastic body 14 can be a spring, also steel spring, also can adopt energy disperser, elastic body 14 shown in Fig. 2 is energy disperser, there is extension spring energy disperser inside, the interior pipe outer end of two energy dispersers is connected with the outer end of two connecting rods 13 of back vehicle frame 2 respectively, and the outer tube outer end of two energy dispersers links to each other with the two side at support bend pipe 15 middle parts of front vehicle frame 1 respectively.Above-mentioned energy disperser can stretch under inner extension spring effect or compress certain distance, tilts about each 25 degree so the standpipe 4 of front vehicle frame 1 can prolong the ground perpendicular line, and alerting ability is fine.Transmission device of the present utility model can change following structure into, front portion at back vehicle frame 2 is connected with axle drive shaft 16 downwards, the middle part of this axle drive shaft 16 is provided with primary flywheel 17, two ends are provided with auxilliary flywheel 18, primary flywheel 17 links to each other with pedal power floral disc 20 by main gear chain 19, and the auxilliary driving chain 21 that two auxilliary flywheels 18 pass through separately links to each other with flywheel 22 on two trailing wheels 10.When driving floral disc 20 so by bike, it just drives axle drive shaft 16 by main gear chain 19 and primary flywheel 17 and rotates, and axle drive shaft 16 drives two trailing wheels 10 by two auxilliary flywheels 18 and auxilliary driving chain 21 again and rotates, and finishes the operational process of three-wheel vehicle.The utility model also can adopt other transmission device.When three-wheel vehicle of the present utility model moves, because front vehicle frame 1 and back vehicle frame 2 are for flexibly connecting, then meeting the bad or trailing wheel in road surface when running into obstacle and tilting, the utility model just makes front vehicle frame 1 held stationary under the effect of elastic body 14, vehicle frame 2 does not tilt together subsequently, so prevented the generation of rollover phenomenon.In like manner, when the utility model sharply turning, because the flexible connection of forward and backward vehicle frame 1,2 and the effect of elastic body 14, so turn radius is little, alerting ability is good, the rollover accident can not occur, is with a wide range of applications.
