摘要： Provided are a speed changer device, a forward/reverse switchover device for converting output of the speed changer device into forward traveling power and reverse traveling power, a rear wheel differential mechanism for inputting output of the forward/reverse switchover device and transmitting it to rear wheels, and a gear transmission mechanism for transmitting power of an output shaft of the forward/reverse switchover device to an input shaft of the rear wheel differential mechanism. A transmission case is separable into a front case portion accommodating the speed changer device and a rear case portion accommodating the forward/reverse switchover device, the rear wheel differential mechanism and the gear transmission mechanism. The gear transmission mechanism is detachably provided at a portion of the inside of the transmission case which portion corresponds to a front end portion of the rear case portion.

摘要： A rear mount power take-off for a transmission includes a housing assembly configured to be mounted in an opening in the transmission. A power take-off shaft includes an externally splined end extending into an opening in the housing assembly and is configured to be driven by a component of the transmission. A guide sleeve is received in the housing assembly and includes an exterior shoulder opposing an interior retaining shoulder of the housing assembly, the guide sleeve further including an interior shoulder. A spring biases the guide sleeve against the interior retaining shoulder of the housing assembly. A coupler sleeve is secured to an interior of the guide sleeve and includes a first internal spline for selective engagement with the externally splined end of the power take-off input shaft and a second internal spline configured to engage a power take-off device.

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 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 drivetrain system includes a first drive gear driven by a first motor and a second drive gear driven by a second motor. The first drive gear and the second drive gear are arranged along the axis. The first drive gear includes a first extension and the second drive gear includes a second extension arranged radially within and axially overlapping the first extension. The drivetrain system includes a system of bearings arranged between the first drive gear and the second drive gear, either drive gear and a stationary component, or a combination thereof. In some embodiments, the drivetrain system includes a clutch assembly arranged between the first drive gear and the second drive gear that interfaces to the first drive gear and to the second drive gear. The clutch assembly allows the drive gears to be locked or otherwise engaged to improve torque transfer.
