Description

Trailer

The present invention is about a kind of trailer, concrete relevant sulky vehicle, the single wheel trailer of using as bicycle or motor-car.

The trailer that has single flower wheel for bicycle or motor-car has been on record, is that this trailer is always not very successful, because tend to unstable in the time advancing fast or turn.

So one object of the present invention is just to provide a kind of trailer, even under quite at a high speed, can stablizes and advance, and not damage the maneuvering performance of towing vehicle.

A kind of trailer for two-wheel vehicles proposing according to the present invention, have one can carrying goods main component, and have a front end and a rear end;

There is a wheel to rotate on the rear end of main body, axle in basic horizontal;

There is an attaching parts at the front end of main component; generally stretch to main component front upper place; there is hanging device in its upper end to articulate with towing vehicle; this hanging device makes trailer and the towing vehicle mutually can be around the axle of first this horizontal positioned of foundation, with this second axis rotation vertical with the first axle of a foundation;

In Fig. 1 of accompanying drawing, with " A ", " B ", " C ", the ratio of the length that " D " and " E " represents is as follows:

(I) ratio A: B is between 1: 4 and 1: 6

(II) ratio A: C is between 1: 3 and 1: 4;

(III) ratio A: D is approximately not more than 1: 3;

(IV) ratio E: A is between 1: 1.3 and 1: 1.7.

According to a desirable embodiment of the present invention, length " A ", " B ", and " C ", the ratio of " D " and " E " is as follows:

(I) ratio A: B is about 1: 5;

(II) ratio A: C is about 1: 4;

(III) ratio A: D is about 1: 3;

(IV) ratio E: A is about 1: 1.5.

Hanging device can change, thereby in the time articulating with towing vehicle, the second pivot of hanging device and upright position tilt, thereby the second pivot and one connect angle between the straight line (dotting in Fig. 1) of rotation of wheel axle and the imagination of hanging device horizontal pivot (in Fig. 1 with symbol " a " expression), between 70 ° and 110 °.

In a desirable embodiment, angle α is about 90 °.

According to finding, if do not observe A presented above, B, C, the length ratio between D and E, as present regular practice, in the time advancing at a high speed, trailer tends to unstable, and damages the maneuvering performance of towing vehicle so.If find that again angle α does not propose in limit in the above, will cause so trailer wheel to have unsuitable strain, cause wheel to rock, in the time that high-speed downstream enters relatively, even wheel may be damaged, the second pivot of inclination also plays a part to make trailer stable in the time turning.

Now by way of example, be described herein with reference to accompanying drawing as follows:

Fig. 1 is the lateral plan of trailer of the present invention, and the trailer articulating with bicycle is shown;

Fig. 2 is the transparent view of the trailer in Fig. 1;

Fig. 3 is the hanging device lateral plan of the trailer in Fig. 1.

Label 10 in Fig. 1 and Fig. 2, the overall picture of expression trailer, has a main component 12, has in its back-end a wheel 14, and front end has attaching parts 16, generally stretches out to front upper place from main component 12.Attaching parts 16 is provided with hanging device 18 in upper end, in order to trailer 10 and two-wheel towing vehicle are articulated, towing vehicle only shows its some as 20(Fig. 1 such as bicycles).

Main component 12 is oblong substantially, and form is that side's bucket (receptacle) is in order to load trailer 10 handling loads.Can add a cover (not shown) according to wish.

Wheel 14 is conventional cycle wheel, and its installation method is conducive to rotation on the horizontal shaft 22 of main component 12 rear ends.As seen from Figure 2, main component 12 has a notch 12.1 in rearward end, holds wheel 14.Wheel 14 is placed along the longitudinal centerline of main component 12.

Attaching parts 16 has a pair of lever arm leaving mutually 16.1 and 16.2, in the direction to hanging device 18, moves closer to mutually, is provided with crossbeam 16.3 above.

Hanging device 18 has a Y-piece 18.1 to be located at the end of attaching parts 16, there is a sleeve pipe 18.2 to be connected with Y-piece 18.1, in order to around a horizontal shaft 24, do rotatablely moving with respect to Y-piece 18.1, in sleeve pipe 18.2, there is one 18.3, on support 18.5, there is connecting arm 18.4, can be in order to be commonly called as back vent-translator with the after-frame 20.1(of bicycle 20) be connected.This arrangement be convenient to bicycle 20 and trailer 10 around second axle 26 rotate, the second axle 26 is axle 18.3, it is vertical with pivot 24.Therefore hanging device 18 is versatile spindle type, and rotatablely moving around two mutually perpendicular axles is provided.

Whole arrangement can more clearly be found out from Fig. 3, in the time that support 18.5 is connected with bicycle 20, axle 18.3, that is second pivot 26, tilt with upright position, the α angle being formed by the straight line (illustrating with dotted line in Fig. 1) of the imagination between the axle 26 tilting and connection wheel 14 S. A.s 22 and horizontal shaft 24 is about 90 °.

As can be seen from Figure 1, main component 12 stretches downwards from the S. A. 22 of wheel 14, by a vertical distance " A ", then forward by a horizontal throw " B ", the outer rim of wheel 14 or the wheel rim that contacts to earth, be positioned at main component 12 belows, lower end, or below, chassis vertical distance is the place of " E ".

The horizontal pivot 24 of hanging device 18, is positioned at main component 12 tops, bottom, and vertical distance is the place of " C ", and horizontal pivot 24 is positioned at the place of main component 12 front end horizontal throws for " D ", as shown in Figure 1.

Although above-mentioned length " A ", " B ", " C ", the absolute value of " D " and " E " might not be conclusive, it is found that the optimum stabilization in order to obtain trailer running, should adopt the ratio between following length, that is:

A: B should be between 1: 4 to 1: 6, take 1: 5 as good;

A: C should be between 1: 3 to 1: 4, take 1: 4 as best;

A: D should approximately be not more than 1: 3, in the time making towing vehicle with bicycle, take 1: 3 as best;

E: A should be between 1: 1.3 to 1: 1.7, take 1: 1.5 as best.

If observed the length ratio of above-mentioned A: C and A: D, the concrete shape of the curved arc forward and upwards of attaching parts 16, can select with wish so.

Trailer 10 can be used in conjunction with the bicycle of various sizes, and the diameter of wheel 14 is not necessarily identical with the wheel diameter of towing vehicle.

Although what above narration related to is being used in conjunction with of trailer 10 and bicycle, be understood that trailer 10 can also be used in conjunction with motor-car, at this moment trailer 10 can arrange levitation device, bumper and drg.
