Description

This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1916 edition. Excerpt: ...force becomes very great. However, the maximum strains do not occur in ordinary driving, but when the wheels suddenly strike a large obstacle. Then the resistance to rotation of the wheel suddenly increases, perhaps to the limit of adhesion to the road surface, while the flywheel momentum, adding to the normal torque of the engine, produces a momentary driving effect greater than any produced in regular running. The torque and radius rods must be capable of taking such stresses. It is, therefore, very necessary that they should occasionally be examined for fracture, and replaced without delay if any breakage occur, although the failure of a torque rod is not nearly so serious as the breaking of a radius rod, or of a gear wheel within the axle casing. Radius Rods for Chain Drive.--The radius rods on chain-driven vehicles also serve for the purpose of adjusting the chains. They also take up the reaction due to the chain pull, and transmit the driving thrust or braking pull from the rear axle to the frame. These rods must be jointed at both ends, so as to permit of free play of the springs, and the joint centres should preferably lie in the axes of the sprockets, so that any play of the springs will not affect the sprocket centre distances. A most satisfactory form of radius rod for a chain-driven vehicle is shown in Fig. 59, which form of construction allows of the front ends encircling the ends of the differential shaft bearings, whilst the rear ends embrace the axle body. With this form of rod it is not convenient to use the latter as a torque member to take up the brake reaction. In that case the brake-reaction has to be taken up by the body springs by connection of the brake support with the spring seat, or the brake support may be...show more
