Abstract
A trike with two front wheels comprises a frame, a rear wheel, a rear axle, a shock absorber and two front wheels controlled by the steering mast. The utility model is characterized in that two front wheels placed side by side are connected together through a connecting mechanism and a steering mast. The utility model has the advantages of simple structure and convenient usage; and the utility model remarkably increases the loading ability of the front wheel and prolongs the life span of the front wheel; the utility model is also great in the prevention of side overturn of the vehicle.
Description
(1), affiliated technical field
The utility model relates to a kind of three-wheel vehicle, particularly a kind of motor-tricycle.
(2), technical background
Existing motor-tricycle generally comprises vehicle frame, trailing wheel, back axle, bumper and is subjected to a front-wheel of column control.Because the hermetically sealed vehicle body of present motor-tricycle, metal body, big Windshield, glass for vehicle window and thick car door, make that the front-wheel load-bearing of motor-tricycle is increasing, even to the stage that can't bear to stand, shorten the service life of front-wheel greatly, even the phenomenon of front-wheel tyre-burst occurs.The deficiency of having only the motor-tricycle of a front-wheel depositing poor stability, when tempo turn, the phenomenon of rollover happens occasionally.
(3), summary of the invention
The purpose of this utility model just provides a kind of three-wheel vehicle of compound front-wheel simple in structure, easy to use, and it can increase the load-carrying capacity of front-wheel significantly, plays good effect to preventing rollover.
The purpose of this utility model is to realize that by such technical scheme it includes vehicle frame, trailing wheel, back axle, bumper and is subjected to the front-wheel of column control, it is characterized in that: two and front-wheel together are connected with Steering gear by bindiny mechanism.Because with the supporting of two front-wheels as the car body front end, it will strengthen load-carrying capacity greatly, prolong the service life of front-wheel, and because of two front-wheel broadening areal of support, the possibility that car body is turned on one's side significantly reduces.
Owing to adopted technique scheme, the utlity model has advantages such as simple in structure, easy to use, it enlarges markedly the load-carrying capacity of front-wheel, prolongs the service life of front-wheel, and good effect is played in the rollover that prevents car body.
(4), description of drawings
Description of drawings of the present utility model is as follows:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that front-wheel is by bindiny mechanism and the assembling scheme drawing that turns to rotating shaft.
Among the figure: 1. front-wheel; 2. vehicle frame; 3. trailing wheel; 4. back axle; 5. Steering gear; 6. universal knot transmission shaft; 7. bearing; 8. steering driving shaft; 9. bumper; 10.U type pipe assembly; 11. front wheel spindle; 12. axis pin base; 13. pivot pin; 14. support set; 15. packing ring; 16. circular nut; 17. bearing; 18. rotation seat combination; 19. brake shoes subpanel assembly; 20. connection pipe; 21. male splines; 22. female splines.
(5), the specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1, the utility model includes vehicle frame 2, trailing wheel 3, back axle 4, bumper 9 and is subjected to the front-wheel 1 of Steering gear 5 control, it is characterized in that: two and front-wheel 1 together are connected with Steering gear 5 by bindiny mechanism.Because with the supporting of two front-wheels as the car body front end, it will strengthen load-carrying capacity greatly, prolong the service life of front-wheel, and because of two front-wheel broadening areal of support, the possibility that car body is turned on one's side significantly reduces.
As Fig. 1, shown in 2, bindiny mechanism includes U type pipe assembly 10, steering driving shaft 8, universal knot transmission shaft 6 and front wheel spindle 11, two front-wheels 1 are positioned in the middle of the U type pipe assembly 10 side by side, front wheel spindle 11 is by support set 14, the centre hole that nut passes two front-wheels 1 versatilely is connected to each other front-wheel 1 and U type pipe assembly 10, Steering gear 5 is connected by the male splines 21 of universal knot transmission shaft 6 lower ends and the female splines 22 of steering driving shaft 8 upper ends, the bottom of steering driving shaft 8 is by pivot pin 13, nut and the axis pin base 12 that is fixedly arranged on the U type pipe assembly are connected with U type pipe assembly 10, and steering driving shaft 8 is connected with vehicle frame 2 by bearing 7.
As shown in Figure 3, can exchange in order to make between front-wheel and the trailing wheel, the structure of front-wheel can be identical with trailing wheel, only need two brake shoes subpanels 19 are welded into an integral body with connection pipe 20 respectively, after rotation seat combination 18 was pressed into bearing 17, integral body was pressed in the brake shoes subpanel assembly 19 again, screwed in circular nut 16, load onto packing ring 15, front-wheel 1 is installed in the rotation seat combination 18.So, because the trailing wheel load-bearing is bigger, and the brake use is more, and trailing wheel is worn and torn easily, only needs front-wheel that wearing and tearing are less and trailing wheel to exchange, and this has prolonged the service life of wheel undoubtedly again.When long-term travel, only need to be equipped with a reserve wheel.
