摘要： A transmission includes an input shaft coupled to a prime mover, a countershaft, main shaft, and an output shaft, with gears between the countershaft and the main shaft. The shift actuator is mounted on an exterior wall of a housing including the countershaft and the main shaft. A shift control circuit operates a shift actuator using a first opposing pulse command and a first actuating pulse command, and releases pressure with shift actuating and opposing volumes of the shift actuator upon determining a shift completion event.

摘要： A transmission includes an input shaft coupled to a prime mover, a countershaft, main shaft, and an output shaft, with gears between the countershaft and the main shaft. A shift actuator selectively couples the input shaft to the main shaft by rotatably coupling gears between the countershaft and the main shaft. The shift actuator is mounted on an exterior wall of a housing including the countershaft and the main shaft. An integrated actuator housing includes a single external power access for the shift actuator. A controller interprets controls the shift actuator with actuating and opposing pulses, and interprets a shaft displacement angle, determines if the transmission is in an imminent zero or zero torque region, and performs a transmission operation in response to the transmission in the imminent zero or zero torque region.

摘要： A method of controlling a transmission of an electric vehicle of the present disclosure includes: applying a driving force to an actuator of a synchronizer by means of a controller such that the synchronizer is disengaged from a current gear stage, when a power-on shifting instruction to shift from the current gear stage to a desired gear stage is given; engaging a servo-clutch by means of the controller such that torque is transmitted from an input shaft to an output shaft through a servo-gear unit, after the applying of a driving force; and disengaging the synchronizer from the current gear stage using a driving force of the actuator, when torque of the current gear stage is switched to the servo-gear unit, after the engaging of the servo-clutch.

摘要： The invention relates to a multistage transmission for an internal combustion engine with a disconnect-type clutch, a drive shaft and a driven shift on which engaged gear wheels are arranged to achieve different gear steps. Clutches (S1 to S4) actuated via shift forks (6 to 12) are used to move the speed gears to generate a frictional connection with the gear shaft (2, 4). The gear change is effected by means of a control cable and/or gearshift linkage. It is proposed that the gear pairs for the even gears (G2, G4, G6) and for the odd gears (G1, G3, G5, G7) are arranged side by side in the manner of a dual clutch gear set. To implement an H shift pattern to actuate the clutches (S1 to S4) of the even gears (G2, G4, G6) and the odd gears (G1, G3, G5, G7) a shifter shaft (14, 16) is provided, respectively. The two shifter shafts can be controlled via a common selector and/or shift control system.

摘要： A proportional pressure reducing valve includes a spool having a first end connected to a solenoid and a second end exposed to a feedback chamber. The spool is formed with a groove for allowing a supply port to communicate with an output port when the spool is driven by the solenoid in proportion to solenoid current under balanced condition of an axial force of the solenoid and feedback pressure. The pressure reducing valve further comprises a pressure reduction valve including a second spool formed with a path, for relieving hydraulic pressure within the feedback chamber to the drain port, when output port pressure rises a predetermined relief pressure, to sharply increase the output port pressure up to the supply pressure in proportion to the current passed through the solenoid.

摘要： Disclosed herein is a mechanism for preventing misoperation, that is, change from a four-wheel drive operation to a two-wheel drive operation at a low speed geared position or select-operation to a low speed gear during a two-wheel drive operation in a manual transmission which permits change from a two-wheel drive operation to a four-wheel drive operation and vice versa and also permits a shift-operation to a low speed gear upon running on a steep slope, sandy place and rough road. The mechanism comprises a stopper arm extending from a shift-and-select lever toward a drive changing shaft and a stopper surface formed on one end of the drive changing shaft. The stopper surface is effective to abut against the stopper arm in the two-wheel drive position of the drive changing shaft and is effective to prevent the shift-and-select lever from engaging the shift head fixed to the fork shaft for a low speed gear.

摘要： A gear-shift mechanism for a motor vehicle having a change-speed transmission equipped with a speed-range selection device. The mechanism has a multi-speed gear-shift transmission unit and a range-shift transmission unit. The mechanism incorporates a shift control level whose movement can be transferred via a gear-selector passage and via several gear-shift passages to a gear-shaft which is supported in a rotating manner and can be axially moved inside a housing. The shaft loosely supports gear shifting levers which can be engaged on the shaft and locked in position in a non-revolving manner after an axial movement of the gear-shift shaft caused by the respective gear-selecting operations of the shift-control lever. The arrangement being characterized in that for the purpose of establishing a non-revolving engagement of the gear-shift transmission unit's shifter levers (13, 14) on the shifting shaft (27), the latter is provided with two engaging members (28, 29) arranged at an axial distance to each other and alternatively moved into an operating connection with the shifter levers (13, 14). The arrangement further characterized in that the range-shift transmission unit can be operated by a shifting mechanism (40) which is controlled by an axially moveable shift finger (37). The finger (37) is loosely connected to the shifting shaft (27) in the direction of rotation and is in a fixed connection with the shifting shaft (27) in an axial direction.
