TENSILE FORCE APPLYING DEVICE FOR MECHANICAL POWER TRANSMISSION, TRANSMISSION HAVING THE SAME AND AUTOMOBILE ENGINE HAVING THE TRANSMISSION

摘要

PROBLEM TO BE SOLVED: To reduce noises and oscillations, and obtain excellent dynamic and static characteristics by arranging a pressing means for processing a belt, a repulsion means for providing the means with belt-pressing force, and a cover on the pressing means for eliminating oscillation. ;SOLUTION: A belt 3 serving as a power transmission of a vehicle passes on a pulley 5 on a crank shaft 7, a pulley 9 on a shaft of an ac generator, and is sequentially wound around a deflector wheel 11, a pulley 13 on a shaft of a power steering hydraulic pump, and a pulley 15 on a shaft of a water pump, for transmitting power to accessories. A tensile force applying device 19 applies tensile force to the belt 3 while pressing a wheel 17 covered with a cover 37 against an outer surface of the belt 3. The device 19 has a main body 21 which has one end pivoted (23) to an engine body, and the other end to that one end of a bell crank 27 is pivoted, the bell crank has a free end provided with the wheel 17. A coil spring 33 is arranged on the main body 21 as a repulsion means.;COPYRIGHT: (C)1998,JPO
