摘要： Methods and systems for a multi-ratio gear box and four speed transmission are provided. In one example, a first shaft is coupled to one or more input speed reduction gear sets. A second shaft is coupled to a multi-range clutch having a first position and a second position allowing for two speeds. A third shaft is coupled to a low-speed clutch and a fourth shaft is coupled to a high-speed clutch, together doubling the number of speeds. The high and low-speed clutches provide a large gear spread that allow the multi-range clutches to have a reduced gear spread, overall reducing the required size of the transmission. A fifth shaft, coupled to the fourth shaft via a gear, may be an output shaft spaced away from the electric motors, thereby creating a short flange to flange distance.

The electric drive unit, in one example, includes a first motor and a second motor arranged parallel to each other and rotationally coupled to a first input gear that is fixedly coupled to a first transmission shaft and a first clutch arranged coaxial to a second clutch. The drive unit further includes a second transmission shaft with an output gear rotationally coupled thereto and including a first and second mechanical interface configured to rotationally couple to a first drive axle and a second drive axle, where the output gear meshes with a gear that is directly rotationally coupled to a carrier in a planetary gear set.

摘要： Methods and systems are provided for reducing vehicle movement during standstill. In one example, a method for a hybrid or electric vehicle may include monitoring a requested torque of an electric machine and a clutch position, predicting a torque at an output shaft by multiplying the requested torque and clutch position, and operating the hybrid or electric vehicle in a default state in response to an indication of a predicted torque exceeding a threshold torque.

摘要： A driveline system and driveline operating method are provided herein. In one example, the driveline system includes a hydraulic coupling designed to rotationally couple to a prime mover and an output interface designed to rotationally couple to a downstream driveline component, and a power take-off (PTO) assembly. The PTO assembly includes a first pump gear rotationally coupled to an input gear that is directly coupled to the output interface, where the first pump gear is designed to rotationally couple to a first pump via a first pump shaft interface and a first pump adapter designed to mount to the first pump.

摘要： The present document relates to a method of disengaging a clutching device. The method comprises sweeping an output torque of an electric motor drivingly connected to the clutching device such that a torque transmitted by the clutching device vanishes at least temporarily during the sweep, and disengaging the clutching device during the sweep. The present document further relates to an electric driveline for carrying out the method.
