    摘要: PROBLEM TO BE SOLVED: To provide a drive pinion capable of reducing noise while satisfying both of flexural rigidity and torsional rigidity that are required. SOLUTION: The drive pinion 74 which is disposed between the propeller shaft 65 and rear differential 71 of a vehicle and transmits a rotation drive power transmitted through the propeller shaft 65 to the rear differential 71 includes a shaft member 20 rotatable about the center axis 11, and a cylindrical member 30 rotatable about the center axis 11 integrally with the shaft member 20. The cylindrical member 30 extends from the one end 76 of the drive pinion 74 to the other end 77 and is disposed to cover the outer circumferential surface 21 of the shaft member 20. The drive pinion 74 is pivoted by a unit ball bearing 12 only at the one end 76. COPYRIGHT: (C)2010,JPO&INPIT

    摘要: PROBLEM TO BE SOLVED: To provide a compact and low-cost vibration damping device capable of minimizing an adverse influence on a compliance characteristic of a rotary shaft in a rotational direction thereof and sufficiently exerting a vibration damping effect by an inertial mass for a vibration transmission sensitivity in a translational direction other than the rotational direction; and to provide a low-cost vehicular power transmission device capable of sufficiently reducing the level of vibration noise such as a whining noise.
    SOLUTION: A vibration damping device includes a mass body 12 disposed spaced apart from a rotational center axis CL of a rotary shaft 11 by a certain distance, and a rolling bearing 13 that rotatably supports the mass body 12 with respect to the rotary shaft 11 and holds a support posture of the mass body 12 with respect to the rotational center axis CL of the rotary shaft 11 constant.

    摘要: PROBLEM TO BE SOLVED: To provide a unique carrier and differential assembly configuration for a drive axle.
    SOLUTION: This carrier assembly for a drive axle includes a pinion and ring gear input operably coupled to a differential assembly. The differential assembly includes first and second case halves attached to each other at an interface to define a case split line, and a differential gear assembly supported by the first and second case halves with the gear assembly being operably coupled to drive a pair of laterally spaced wheels. The ring gear, first case half and second case half are all connected together via a single bolted joint with the case split line being located behind the ring gear. The differential housing is supported on a pair of tapered roller bearings having a diverging apex configuration to reduce cup rotation. The pinion gear is solely supported by a pair of tapered roller bearings positioned on opposite sides of the ring gear. A two-piece pinion cage supports both pinion bearings and facilitates the setting of preload with the use of external shims.
