Filed: 1997-10-15
Abstract: PROBLEM TO BE SOLVED: To reduce the weight of a vehicle, to aim at the straight traveling stability, and to restrict the rolling in an automobile provided with plural front axles and plural rear axles by installing single tire in each axle. SOLUTION: In an automobile provided with two front axles and two rear axles, each one tire is installed in each axle so that eight single tires in total are installed. Four tires 3a, 3b are respectively installed in right and left of the two front axles, and four tires 4a, 4b are installed in right and left of the two rear axles. With this structure, since the number of axle is increased in relation to the upper limit of the axle-load so as to improve the loading capacity, high loading capacity is realized. Since the load is evenly applied to the four axles, straight traveling stability is improved, and vibration of a load carrying platform is reduced, balance of abrasion of the tires is taken. Even in a vehicle provided with two front axles and two rear axles, since the number of tires to be installed is eight, weight of the vehicle is reduced, and the cost is lowered.
