摘要： A lock-up torque converter for automatic transmissions which transmits the torque of an internal combustion engine from the engine crankshaft to the transmission input shaft is disclosed. The torque converter includes a converter cover, a turbine hub receiving the input shaft to provide a driving connection, a clutch piston slidably mounted on the turbine hub, and a turbine runner having the outer shell drivingly connected to the hub. The torque converter comprises a first torsional damper operably connected between the clutch piston and the turbine hub to provide a driving connection only when the clutch piston engages the converter cover, and a second torsional damper operably connected between the crankshaft and the converter cover to provide a driving connection during operation of the engine. During operation of the lock-up mechanism, the two dampers cooperatively operate in series with each other to provide an optimum damping effect.

摘要： A shock absorber is provided a piston stroke dependent variable shock absorbing characteristics by a first and second flow restrictions associated with a piston. The first and second flow restrictions are arranged in a fluid path for communicating first and second working chambers defined within a shock absorber cylindrical housing in series. The first flow restriction associated with an orifice forming a part of the fluid path and has a predetermined relief pressure, for providing a predetermined first fixed flow restriction rate in response to a pressure difference between the first and second chambers smaller than or equal to the relief pressure and providing a second variable flow restriction rate in response to a pressure difference between the first and second chambers greater than the relief pressure. The second flow restriction is associated with the orifice for providing a third variable flow restriction rate variable depending upon the pressure difference between the first and second chamber.

摘要： A torsional vibration damper is capable of neutralizing vibrations with a relatively large amplitude, and includes a pair of strengthened equalizers. The damper transmits a torque between a drive plate operatively connected to a torque input member, and hub operatively connected to a torque output member. The hub has a plurality of hub arms extending outward from its outer periphery with an equal angular. A pair of equalizers is journalled on the outer peripheries of and floating independently of said hub arms, each equalizer including an annular portion and arm portions extending inward from the inner periphery of the annular portion. The arm portions of two equalizers alternate between neighboring hub arms. Compression spring sets are interposed in serial between the arm portions of both the equalizers and between the arm portions and the hub arms. The drive plate engages the groups of the compression spring sets by means of both the side inner edges of arcuate windows which are defined in the drive plate and have the same arclength to that of the neighboring hub arms.

摘要： A piston head block is provided with smaller exernal diameter at the portion where a cut-out for receiving a lubricant injection nozzle that remaining portion. With the smaller diameter, a clearance or gap is formed between the internal surface of an engine cylinder and the external surface of the smaller diameter portion. Therefore, during piston stroke, the smaller diameter portion, in which the lubricant injection nozzle receptacle cut-out is formed, becomes free from the transverse stress.
