Abstract: A multi-ratio rotorcraft drive system and a method of changing gear ratios thereof are disclosed. According to one embodiment, the multi-ratio rotorcraft drive system comprises a rotor system comprising one or more rotors and one or more engines. Each engine of the one or more engines is coupled to the rotor system through a multi-ratio transmission. The multi-ratio transmission comprises an output shaft coupled to the rotor system, an input shaft coupled to a respective engine of the one or more engines, a high speed clutch integrated into a high speed gear train, and a low speed clutch integrated into a low speed gear train. The high speed clutch and the low speed clutch are freewheeling clutches without a friction plate and are capable of disconnecting the output shaft and the input shaft in an overrunning condition when the output shaft spins faster than the input shaft.

Abstract: A method for the control of an automatic transmission during a change of ratio procedure, wherein the synchronous speed of rotation (SD) for the new transmission gear-stage lies under the no-load speed of rotation (LD) of a drive motor which can be connected to the transmission and wherein a gear-stage engagement actuator for the engagement of a new transmission gear-stage is then activated, when the transmission input speed of rotation (GED) has reached a predetermined speed of rotation window (F), which window also encompasses the synchronous speed of rotation (SD). In order to make such a shifting method more comfortable than previously, the invented method deviates from that procedure based on downshifting, which has been customary up to this time and rather proceeds in a upshifting mode.

Abstract: A method and system for executing a shift from a first fixed gear to a second fixed gear in a powertrain system comprising a two-mode, compound-split, electro-mechanical transmission operative to receive a speed input from an engine is described. It includes deactivating an off-going clutch, and generating a time-based profile for rotational speed of an oncoming clutch. The input speed is controlled based upon the rotational speed of the oncoming clutch and an output of the transmission. The oncoming clutch is actuated, preferably when the input speed is synchronized with a rotational speed of an output shaft of the transmission multiplied by a gear ratio of the second fixed gear, preferably after a predetermined elapsed period of time in the range of 500 milliseconds.

Abstract: This is a constant-mesh transmission that uses special latches, electromagnetic actuators to operate said latches, and an associated computerized control unit to command said actuators and, at the same time, synchronize the speed of the motor/engine and the gear trains with the speed of the transmission output shaft. During gear ratio changes, the transmission control cooperates with the motor/engine control in such a way that speed differences between—and torque transmitted through—the gear trains involved and the output shaft are minimal; this permits effortless and on-the-fly coupling and decoupling of gears to/from the output shaft, without requiring any clutch operation. This transmission can be used in a variety of automotive and industrial applications, and is mainly intended for automotive vehicles with internal combustion engines.

Abstract: A system for controlling vehicle braking operation includes a mechanism for determining desired service brake force, a mechanism for determining vehicle deceleration, an electronically actuatable engine compression brake unit, an electronically controllable turbocharger boost pressure adjustment device and a transmission including a number of automatically selectable gear ratios, wherein each of these components are coupled to a control computer. The control computer is operable to activate the engine compression brakes whenever service brake action is detected, and to modulate the downshift engine speed points of the transmission as a function of the desired brake force. The boost pressure adjustment device and the engine compression brake may optionally be controlled to maintain a vehicle deceleration rate below a deceleration rate threshold. Alternatively, the downshift engine speed points may be controlled to maintain the vehicle deceleration rate below the deceleration rate threshold.

Abstract: A control apparatus (64) for a transmission. The transmission includes first and second transmission lines (7 8), (10, 11) disposed in parallel between an upstream transmission shaft (2) for receiving power from an engine (1) and a downstream transmission shaft (4) for transmitting the power to a traveling unit (53, 54); a hydraulic multiple disc transmission clutch (6) disposed transmission-wise upstream or downstream of the first and second transmission lines, the power of the upstream transmission shaft being transmitted via one of the first and second transmission lines to the downstream transmission shaft; a first gear change-speed mechanism (13) disposed between either the upstream transmission shaft or the downstream transmission shaft and the first transmission line, the first gear change-speed mechanism having a plurality of speed positions; a first actuator (35) for operating the first gear change-speed mechanism; a first friction clutch (9) incorporated in the first transmission line; a second gear change-speed mechanism (15) disposed between either the upstream transmission shaft or the downstream transmission shaft and the second transmission line, the second gear change-speed mechanism having a plurality of speed positions; a second actuator (37) for operating the second gear change-speed mechanism; and a second friction clutch (12) incorporated in the second transmission line. When the power is being transmitted via the first transmission line, a first controlling means operates the second gear change-speed mechanism into a predetermined speed position by means of the second actuator and operates the first friction clutch from a transmitting state to a non-transmitting state and simultaneously operates the second friction clutch from a non-transmitting state to a transmitting state, thereby to realize a progressive shifting of the transmission clutch from a transmitting state to a semi-transmitting state.
