摘要:
A piston actuated synchronizer system for a split torque transmission where the piston is attached directly to the synchronizer shift collar on the synchronizer centerline to provide the required actuation in a small volume of space and resolve fork and rod deflection issues seen on other synchronizers that use such a system. The piston is pressure applied and spring released. This design also uses a displacement sensor to monitor synchronizer engagement.

A drive arrangement for driving, or for being driven by, a fluid is disclosed. The drive arrangement comprises a rotatable member (40) for receiving the fluid, and having mounted thereon a plurality of drive members (56). The drive members (56) are movable between a drive position, in which the drive members can drive, or be driven by, the fluid, and a non-drive position in which the drive members (56) are substantially prevented from driving or being driven by a fluid received in the rotatable member (40).
摘要:
A multi-speed transmission assembly including a gear box portion having first and second inputs and an output; the first input is connectable to a pump portion of the torque converter, whereas the second output is selectively connectable to an impeller portion of said torque converter such that separate torque converter and direct drive paths are established from a prime mover to the transmission output. Clutches are used to selectively couple the first and second inputs with their associated driving elements. The gear box includes two countershafts having their axes arranged to be parallel and spaced apart from each other and parallel and spaced from an axis of an output shaft. The axes are arranged in a triangular relationship which enables a “straight through” version, a “short drop” version and a “long drop” version of the transmission to be easily manufactured using a commonality of components. By providing different input gear ratios for the first and second inputs, the torque converter can be used as an “energy absorber” under certain vehicle operating conditions, by simultaneously actuating clutches associated with the first and second inputs to produce relative rotational speeds in the impeller and pump portions of the torque converter.

The hydromechanical transmission is all in all designed as a power splitting transmission having at least two hydraulic machines adapted to selectively act as pumps and motors, a control or connecting block, epicyclic gearing and various clutches, the hydraulic machines adapted to selectively act as pumps and motors forming a preassembled unit or subassembly with the control or connecting block. The subassembly, the epicyclic gearing, the clutches and any intermediate shaft required are arranged in a unitary manner in a common housing, in which the various elements are surrounded with a small clearance. the hydraulic machines adapted to selectively act as pumps and motors are arranged within the overall length of the epicyclic gearing and are axially parallel thereto.

A vehicular four-wheel drive system which includes: an oil pump adapted to be actuated by the relative rotations of a first rotating shaft connected to front wheels and a second rotating shaft connected to rear wheels for discharging pressure oil; a hydraulic clutch having a cylinder chamber communicating with the discharge passage of the oil pump; an electromagnetic throttle valve for controlling the discharge pressure of the oil pump; and a control mechanism for changing the throttle opening of the electromagnetic valve in accordance with the running situation of the vehicle.
摘要:
A transmission having a two-stage torque converter with a turbine and two stators, a one-way clutch and a stator shaft, one of the stators being connected to the stator shaft through the one-way clutch. The reverse drive of the stator connected to the stator shaft through the one-way clutch is interconnected to and disconnected from the drive of the turbine through counter gear mounted on counter shafts selectively interconnected and selectively disconnected through clutches mounted on the counter shafts.
摘要:
A speed ratio detecting valve means of torque converter comprising a hub of a stator vane spline fitted onto a fixed shaft and being freely rotatable through a prescribed play angle, the hub being permitted to rotate relative to the fixed shaft by said play angle at a prescribed speed ratio utilizing a phenomenon that the direction of force of a working fluid in the torque converter exerted on the stator vane is reversed when an input-output rotation speed ratio reaches said prescribed value, and causing a fluid passage opening through a fixed shaft inside to an outer periphery of the fixed shaft to joint with or shut off from its jointing part.
摘要:
A power supplying member supplies rotational power in a certain rotational direction to a first member of the transmission, and a power receiving member takes out power from a second member. Several power transmission systems are provided between the first and the second member, which are selectively engagable so as to provide various speed stages between them. Each power transmission system has a clutching mechanism which either can be disconnected so as to freewheel in both rotational directions, or can be connected to transmit rotational power at least in the one rotational direction which is required for transmission of power through that power transmission system from the first member to the second member. A fluid torque converter is provided in the rotational power transmission path of only one of the power transmission systems which provides the lowest gearing ratio between the first member and the second member.
摘要:
In a tank having a pair of supercharged engines for driving the transmission via a hydraulic torque converter having a controllable bypass coupling, vibration control and efficiency are improved by providing for the engines individual fluid couplings with a common output to a controllable converter for adaption to the power level. Controllable guide vanes of the converter serve to block the hydraulic coupling when the bypass coupling is operative.
