Patent ID: 8864156

Claim:
A vehicle having a chassis on which front and rear axles are respectively mounted by an upper pivotal mounting means which is pivoted on the chassis for vertical pivoting movement relative to the chassis and which carries an axle support on which each axle is free to pivot in a roll mode, each axle also being mounted from the chassis by a lower pivotal mounting means which is pivoted on the chassis for vertical pivoting movement relative thereto and which acts on each axle to control fore and aft movement of each axle relative to the chassis, the two pivotal mounting means being mounted on the chassis so that the line of action of the forces applied to the chassis by the upper pivotal mounting means at one end of the chassis is substantially aligned with a line of action of the forces applied to the chassis by the lower pivotal mounting means at the other end the chassis thus reducing the tendency for the chassis to be twisted by the forces applied thereto by the axles.
