摘要： An improved arrangement of locking apparatus for securing the fulcrum ring of a clutch in adjusted position includes a rotatable cam operable from a readily accessible location for forcing a locking bar radially into engagement with a slotted fulcrum ring; a wedge shaped nose on the locking bar is preferred for taking up clearance between the bar and slot in order to eliminate hammering or chucking; the nose of the locking bar may have compound inclination for exerting wedging action both radially and parallel to the axis; the wedging and securing of the locking bar is facilitated by the provision of coaxial hexagonal drive lugs adapted for engagement by wrenches. In addition, an improved interlocking drive connection is provided between the finger of a belleville spring and a release sleeve assuring that the sleeve rotates with the spring.

摘要： The transmission of torsional vibrations from a rotating driving shaft, at the output of an internal combustion engine, to a driven shaft, at the input of a manual transmission, are reduced or eliminated by employing a normally-engaged, oil-cooled wet clutch to interconnect the two shafts, the clutch being controlled to introduce a desired amount of slippage. Slipping the wet clutch to a relatively small extent allows the necessary torque to be transmitted, but any torque fluctuations in the driving shaft will be effectively absorbed and prevented from causing torsional vibrations in the drivetrain.

摘要： A compact arrangement for a continuously variable transmission and power train system is provided to be used in rear wheel drive vehicles. In one arrangement, the input shaft is in-line with the output shaft. In this arrangement, the input shaft, having a hydraulic pump, is connected to an engine by a torque converter. A first transfer gear assembly transfers power from the input shaft to the adjustable input pulley of a continuously variable transmission assembly. The adjustable input pulley transfers power to an adjustable output pulley through a belt. A second transfer gear assembly transfers power from the adjustable output pulley to an output shaft in-line with the input shaft. A forward and reverse gear system having a compound planetary gear set and clutch on the output shaft provides forward, neutral, and reverse gears.

摘要： A control system for a power shifted transmission includes an electrical signal processing system, incorporating a digital processor, which provides output signals to regulate operation of the directional clutch and the range clutches through a plurality of spool valves. A hydraulic stabilizer is connected to a common line supplying the directional clutch, to provide a predetermined amount of fluid with each change in direction, with the remainder of the fluid being provided through a forward-reverse modulating valve. A neutral bleed valve is connected to reduce the measured amount of fluid in the stabilizer when the clutch is being shifted from the neutral position, instead of a full directional change. To improve range shifts, the directional clutch is slipped while the range change is made, and the directional clutch is then re-applied. A horsepower indicator provides the vehicle operator with an instantaneous indication of the vehicle operating efficiency. "Inching" or low speed operation, notwithstanding a high engine speed, is also provided.

摘要： This invention relates to a unique transmission system for applying torque from an engine flywheel to the drive train of an automotive vehicle including a long travel viscous damped torsional damper driven by the flywheel and coupled to a continuously variable transmission which in turn is coupled to a wet drive clutch, the output of which is connected to an output counter shaft for the automotive drive train. An important part of the unique combination is the long travel viscous damped torsional damper of the invention which includes an enclosed, effectively sealed housing contains input and output members coupled through a plurality of series parallel spring sets and immersed in a viscous medium to provide effective viscous damping matched to the effective spring rate of the mechanical damping system to accommodate both transient and steady-state vibrational torques. The damper is especially useful with the continuously variable transmission but is useful in other applications as well.

摘要： A dump valve mechanism for a wet clutch wherein the clutch includes a plurality of friction elements supplied with lubricating and cooling oil when the clutch is engaged and including a fluid pumping means as a part of a release mechanism, the release mechanism being axially movable to a position engaging a brake for a transmission input shaft. The dump valve is defined by a pair of annular surfaces which are opened and separated when the brake is engaged due to relative movement between parts of the release mechanism to divert the lubricant and cooling fluid from the clutch discs as the brake is applied to prevent viscous drag from providing unwanted drive between the friction elements when the clutch is disengaged.

摘要： The operating temperature of an internal combustion engine is maintained within desired limits by employing a single coolant temperature sensor for controlling and coordinating the operation of three different temperature control devices for the engine coolant. When the sensed coolant temperature is in a relatively low range a flow control valve controls the amount of coolant diverted from the engine jacket to a radiator to dissipate heat absorbed by the coolant from the engine. If the coolant temperature exceeds that low range, even though the control valve is fully open and all of the coolant is circulated through the radiator, the sensor then effects the opening of radiator shutters to cause ram air to impinge on the radiator to increase the cooling of the coolant. If the temperature still continues to rise after the shutters are fully open, the coolant sensor causes operation of a variable speed fan drive to blow a sufficient amount of air through the radiator to cool the coolant back down to the desired operating range. Such sequential operation of the three control devices provides close temperature control within a relatively narrow range despite wide variations of external conditions and load on the engine, resulting in higher efficiency and longer engine life.
摘要翻译： 通过使用单个冷却剂温度传感器来控制和协调用于发动机冷却剂的三个不同温度控制装置的操作，内燃机的操作温度保持在期望的限度内。 当感测到的冷却剂温度处于相对低的范围时，流量控制阀控制从发动机护套转移到散热器的冷却剂量，以散发来自发动机的冷却剂吸收的热量。 如果冷却液温度超过该低温范围，即使控制阀完全打开，并且所有冷却液都通过散热器循环，传感器然后实现散热器百叶窗的打开，使冲头空气撞击散热器以增加冷却 的冷却液。 如果在百叶窗完全打开之后温度仍然继续上升，则冷却剂传感器使得可变速风扇驱动器的操作使足够量的空气吹过散热器，以将冷却剂冷却回到期望的操作范围。 尽管外部条件和发动机上的负载有很大变化，三个控制装置的这种连续操作也提供了相对较窄范围内的温度控制，导致更高的效率和更长的发动机寿命。
