Abstract

PURPOSE:To keep the superior weight balance of a chassis by keeping the min. ground height of the front part high by installing an intermediate shaft between a front-wheel driving shaft and an engine. CONSTITUTION:An intermediate shaft 5 is arranged between an engine 3 and a front-wheel driving shaft 4, and sprockets 6 and 7 are installed. The sprocket 6 is linked with a sprocket 9 installed onto the output shaft 8 of a speed change mechanism for transmitting the power of the engine 3, through a chain 10, and the sprocket 7 is linked with a sprocket 11 installed onto a front-wheel driving shaft 4, through a chain 12. The chain line between the sprocket 7 and the sprocket 11 is set at the proper position where the intereference with a suspension installed onto the swing arm 16 of a front wheel 2 is avoided and the weight balance at right and left can be secured, by setting the length of the intermediate shaft 5 to a proper value.

FIG. 1 shows a straddle-type four-wheel vehicle 1 developed for this type of purpose and equipped with low-pressure balloon tires. This type of straddle-type four-wheel vehicle 1 has a four-wheel drive system in order to eliminate the resistance of the front wheels 2, or can be switched to four-wheel drive, front-wheel drive, or rear-wheel drive as necessary. There was a strong desire to do so.
