JP2010023817A - Stably traveling two-wheeler with less stagger - Google Patents

Abstract

<P>PROBLEM TO BE SOLVED: To provide a safe two-wheeler with less stagger and overturning during traveling, even if cargoes and children are put in front part and rear part of the two-wheeler. <P>SOLUTION: Front part deck stay 2 and rear part deck stay 3 are installed in a vehicle body frame 1 of the two-wheeler. Deck frames 6 are mounted in upper parts of the front part and rear part deck stays 2 and 3. Each of auxiliary stays 4 and 5 is installed to reinforce strength of the front part and rear part of the deck frame 6. Fixed ends of the front part and rear part deck stays 2 and 3 are fixed in cantilever to a stay fixing bracket 12 in the lower part of the vehicle body frame 1, each part is not brought into contact with any part of the vehicle body frame 1, and thereby weight concentrates on the stay fixing bracket 12. When cargoes and children are put on the deck frame 6, the load concentrates in an intermediate part of a front wheel and a rear wheel in a lower part of the vehicle body frame 1, and a center of gravity becomes a lower position. As a result, stagger and overturning during traveling can be reduced as compared with the case where the equivalent load is applied to the front wheel part and the rear wheel part in a conventional two-wheeler. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

  The present invention provides a two-wheeled vehicle with little steering wobbling even when a heavy object is mounted or a three-seater passenger including a child rides.

  Conventional motorcycles are very dangerous when they are traveling with children or luggage. That is, when a large load is applied to the front part of the steering wheel, the load concentrates mainly on the front wheel, and when a large load is applied to the rear part, the load concentrates on the rear wheel. In addition, there is a drawback that stable running becomes difficult and dangers such as rollover occur.

  The cause of such a dangerous condition is that the load applied to the front wheels and the rear wheels is extremely unbalanced.For example, if the load applied to the rear wheels is large, the force acts in the direction in which the front wheels are lifted, and the load applied to the front wheels. If it is large, force acts in the direction that the rear wheel is lifted, and the wobbling of the steering wheel increases.

The present invention was invented in order to reduce the drawbacks of wobbling of a motorcycle, and will be described below with reference to the drawings.
FIG. 5 shows a basic configuration of the present invention, that is, a front cargo bed stay 2 and a rear cargo bed stay 3 are provided on the vehicle body frame 1, and the front and rear rear stays 2 and 3 are fixed to the lower part of the vehicle body frame 1. It is installed at a location located in the middle.

  As shown in FIG. 1, the lower parts of the front cargo bed stay 2 and the rear cargo bed stay 3 are fixed to the vehicle body frame 1, and the loading bed frame 6 is mounted and fixed on the upper parts of the front cargo bed stay 2 and the rear cargo bed stay 3. The lower portions of the front cargo bed stay 2 and the rear cargo bed stay 3 are connected and fixed to the stay fixing bracket 12. The shape of the frame and stay may be tubular, rod-like, or plate-like, and these materials may be aluminum, iron, synthetic resin, or glass material.

  As shown in FIG. 2, the front loading platform stay 2 and the rear loading platform stay 3 are not in contact with any part other than the stay fixing bracket 12 of the vehicle body frame 1, and the loading frame 6 is not in contact with the vehicle body frame 1. It is the biggest feature. Therefore, the weight of the child or the luggage is concentrated between the front wheel and the rear wheel and at the lower part of the frame.

  As shown in FIG. 2, the front auxiliary stays 4, 4 ′ and the rear auxiliary stays 5, 5 ′ are installed to prevent the load carrier frame 6 from tilting due to the load when the load is loaded on the load carrier frame 6. A stay fixing bracket 12 for fixing the lower portions of the front and rear cargo bed stays 2 and 3 in a cantilever manner was provided.

  As shown in FIG. 1, a luggage basket 9 and a child seat 7 are mounted on the front part of the loading frame 6, a child is placed on the child seat 7, a luggage is loaded on the luggage basket 9, and a child seat 8 is mounted on the rear part of the loading frame 6. Even when a child is placed on the child seats 7 and 8 and when the luggage is loaded on the luggage bag 9, the total weight of the luggage and the child is concentrated at one place of the stay fixing bracket 12 of the body frame 1.

  Since the total load of the driver, children, and luggage is concentrated only at one location of the stationary bracket 12 of the body frame 1, the total weight is applied to the front and rear wheels in a well-balanced manner. I can do it.

  As shown in FIG. 3, the front cargo bed stay 2 is fixed to the stay fixing bracket 12 at the lower part of the body frame 1 of the motorcycle, and the front cargo bed stay 2 and the vehicle body frame 1 are fixed by the wire 10. By fixing the rear cargo bed stay 3 and the vehicle body frame 1 with the wire 11, the tilt prevention strength of the front cargo bed stay 2 and the rear cargo bed stay 3 is maintained.

  As shown in FIG. 4 and FIG. 5, the structure of fixing the loading platform stay 2 and the loading platform stay 3 to the vehicle body frame 1 as shown in FIG. It is good also as a structure which mounts the luggage bag 9 child seats 7 and 8 in the edge part.

FIG. 7 shows a method of connecting the loading platform stay 2 loading platform stay 3 loading platform frame 1 at the lower part of the body frame 1.
A: The front loading platform stay 2 and the rear loading platform stay 3 are fixed to the loading platform frame 1 by screwing at the stay fixing bracket 12 portion.
B: It is set as the shape which inserts and fixes the front loading platform stay 2 and the rear loading platform stay 3 to 12 portions of the stay fixing bracket.
C: An integrated shape in which the loading platform frame 1 front loading platform stay 2 and rear loading platform stay 3 are not divided is used without using the stay fixing bracket 12.
The above three types were represented.

  Since the present invention is structured as described above, when a child or luggage is placed on the front part of the motorcycle and a child or luggage is placed on the rear part, the weight is concentrated on the stay fixing bracket 12 so that the weight is balanced in the front wheel and rear. The stability of the steering wheel is increased because it is dispersed on the wheels and the center of gravity is low, and the two-wheeled vehicle can travel safely with little wobbling. Further, the body frame 1 and the front / rear loading platform stays 2 and 3 may be additionally modified to the conventional motorcycle.

(Embodiment 1) A front loading platform stay 2 and a rear loading platform stay 3 are installed in the lower part of the middle part of the front wheels and the rear wheels on a body frame 1 of a motorcycle according to the present invention. An overall configuration in which a child and a luggage are mounted on the loading platform frame 6 is shown. (Embodiment 2) FIG. 6 is a perspective view showing a frame structure of (Embodiment 1) of a motorcycle according to the present invention. (Embodiment 3) An overall configuration diagram in which a front loading platform stay 2 and a rear loading platform stay 3 of a two-wheeled vehicle according to the present invention are reinforced by a front wire 10 and a rear wire 11 and children and luggage are placed on the loading platform stays 2 and 3 is shown. FIG. (Embodiment 4) It is the perspective view which showed the frame structure of (Embodiment 3) of the two-wheeled vehicle by this invention. (Embodiment 5) A shape in which a loading frame 6 of a motorcycle according to the present invention is omitted is shown. (Example 6) It is the perspective view which showed the frame structure of (Example 5) of the two-wheeled vehicle by this invention.
