ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a battery receptacle structure in a two-wheeled motor vehicle.
2. Description of the Background Art
A battery receptacle structure in a two-wheeled motor vehicle is shown, for example, in FIG. 1 of Japanese Patent Laid Open No. 175477/96 entitled “An Engine-Motor Power Switching Device in a Two-wheeled Motor Vehicle or the like,” in which a battery
6
(this and the following reference numerals mentioned in connection with the above unexamined publication are quoted from the same publication) is accommodated below a foot rest
38
of a vehicle body frame
2
.
Since the total load of the heavy battery
6
is imposed on the vehicle body frame
2
, the body frame must be very rigid. However, as the rigidity of the body frame is enhanced, its weight becomes heavier.
SUMMARY OF THE INVENTION
It is therefore an object of the present invention to provide a battery receptacle structure for the purpose of reducing the weight of the vehicle body frame
It is a further object of the present invention to provide a battery receptacle structure which reduces the weight of the vehicle body frame while maintaining the frame rigidity.
These and other objects of the present invention are achieved by a battery receptacle structure for a motorcycle including a main frame portion extending generally horizontally, the main frame portion including a pair of laterally spaced-apart side frame members, a front cross member interconnecting forward portions of each of the side frame members, and a rear cross member interconnecting rearward portions of each of the side frame members. A head pipe extends upwardly from the main frame portion. A battery receiving area is located on the main frame portion generally between the side frame members.
A control unit serves as a bottom plate between the paired side frame members and permits batteries to be carried thereon. Therefore, it is no longer necessary to use a separate frame or member for carrying batteries thereon. Accordingly, the weight of the vehicle body and the number of components used are reduced.
Because the control unit closes the bottom of the main frame, the rigidity of the main frame is enhanced. Further, since the control unit is exposed below the main frame, the heat generated in the control unit is dissipated and effectively cooled by the air traveling therepast.
Further scope of applicability of the present invention will become apparent from the detailed description given hereinafter. However, it should be understood that the detailed description and specific examples, while indicating preferred embodiments of the invention, are given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from this detailed description.
