摘要： A shift rail and fork assembly for a transmission includes a shift channel (10) having a pair of side pieces (11) that are connected together by cross pieces (12). A plurality of shift rails (30) are supported on the shift channel for relative sliding movement. A corresponding plurality of shift forks (20) are supported on the shift channel for relative sliding movement. The shift rails (30) are connected to the shift forks (20) for concurrent longitudinal movement. A cross slide (50) is supported on the shift channel for relative lateral movement. The cross slide including a depending tang (51) that selectively cooperates with corresponding slots (31) formed in each of the shift rails for concurrent movement The cross slide (50) can be moved laterally such that the selector tangs (51) engage any desired one of the shift rails (30). An interlock bracket (70) is also supported for lateral movement relative to the shift channel, but is prevent from longitudinal movement. To initiate a shifting operation, a shift lever is first moved in the lateral direction to select one of the shift rails, causing lateral movement of both the cross slide (50) and the interlock bracket (70). The lateral movement of the cross slide causes selector tangs (51) provided thereon to become laterally aligned with a slot (31) formed in a selected one of the shift rails. At the same time, the lateral movement of the interlock bracket (70), causes depending arm portions (72) provided thereon to become laterally aligned with slots formed in all of the other non-selected shift rails. Then, the shift lever is subsequently moved in a longitudinal direction, causing the cross slide, the selected one of the shift rails, and the shift channel to be moved longitudinally therewith. The interlock bracket prevents the non-selected shift rails from moving longitudinally.

摘要： An apparatus and method for operating a continuously variable transmission (CVT), such as a toroidal drive type transmission, is disclosed. The CVT is selectively operated in either a torque control strategy and a ratio control strategy, depending upon the operating conditions of the vehicle. The transition from the torque control strategy to the ratio control strategy (and vice versa) can be accomplished by simultaneously calculating the control pressures that would result from operation in both the torque and ratio control strategies, and further assigning a weighted value to each of such calculated control pressures based upon the current operating conditions. The summation of such weighted values provides a composite control signal that facilitates a smooth transition between the two control strategies. The transition from the torque control strategy to the ratio control strategy preferably occurs before a mode shift is effected.

摘要： An apparatus and method for controlling the operation of a clutch (12) in a partially or fully automated mechanical transmission (13) which is responsive to the actual speed of the vehicle engine (11) for varying the engagement rate of release bearing (33) during re-engagement of the clutch (12). The apparatus includes an electronic controller (20) which initially sets a desired speed for the vehicle engine (11) during the shifting process, determines a rate of engagement movement of a release bearing (33) of the clutch (12), and actuates appropriate valves (41, 42) to initiate the gradual engagement of the clutch (12). The electronic controller (20) sets a first lower engine speed threshold and a second lower engine speed threshold. The magnitude of the first lower engine speed threshold may vary with the amount of depression of an accelerator pedal (24) of the vehicle.

摘要： An apparatus and method for controlling the rate of engagement of a clutch (12) in response to an indication provided by the driver, such as the depression of an accelerator pedal (24) of the vehicle. The apparatus includes an electronic controller (20) which initially determines a start rate as the minimum duty cycle which is required to modulate an engage valve (41) in order to cause movement of a release bearing (33) of the clutch in the engagement direction. Following the receipt of a signal from the operator of the vehicle to initiate the engagement of the clutch, the electronic controller calculates an initial transition rate of movement of the release bearing from a disengaged position to a transition point. The transition rate is determined as a function of the start rate and a position error signal. The position error signal can be calculated as the difference between the actual position of the release bearing and the transition point.

摘要： An apparatus and method for controlling the engagement rate of a clutch in an automated mechanical transmission in response to the depression of an accelerator pedal of the vehicle. The apparatus includes an electronic controller which initially sets a desired engine speed during the shifting process (51), determines a rate of engagement of the clutch (52), and actuates appropriate valves to initiate gradual engagement of the clutch (54). The electronic controller is responsive to depression or rate of depression of the accelerator pedal for incrementing the rate of engagement of the clutch, and to release or rate of release of the accelerator pedal for decrementing the rate of engagement of the clutch. If the accelerator pedal is maintained in a constant position, the rate of engagement of the clutch is unchanged.

摘要： An apparatus and method for controlling the engagement rate of a clutch (12) having an input member (11a) and an output member (13a) for selectively connecting an engine (11) to a transmission (13) includes first and second sensors (25, 21) which generate signals representing the rotational speed of the input and output members (11a, 13a), respectively. A controller (20) generates a desired engine speed signal and a control signal representative of an engagement rate of the clutch (12). The controller (20) modifies the control signal when the rotational speeds of the input member (11a) and the output member (13a) are approximately equal to the desired engine speed. A clutch actuator (16) controls the engagement rate of the clutch (12) in response to the control signal.
