MULTI-SPEED GEARBOX WITH A GEAR-CLUTCH ASSEMBLY
An electric drive axle of a vehicle includes an electric motor having an output shaft. A compound idler assembly is connected to the electric motor. The compound idler assembly includes at least one gear-clutch assembly in driving engagement with the output shaft of the electric motor. A differential is connected to the compound idler assembly, and in selective driving engagement with the compound idler assembly.
Output gearing for a dual motor mixed-speed continuous power transmission
An electric powertrain includes a first electric motor that has an uninterrupted connection with a drive shaft of a vehicle. The electric powertrain further includes a second electric motor that has an interruptible connection with the drive shaft. In one form, this interruptible connection includes a clutch. The electric powertrain further includes a first gear train in the form of a first planetary gear and a second gear train in the form of a second planetary gear. The first gear train, second gear train, and clutch are arranged downstream from the first electric motor and second electric motor.
POWER SHIFTABLE MULTI-GEAR TRANSMISSION HAVING FREEWHEEL
The invention relates to a power-shiftable multi-gear transmission (12) having a driven input shaft (14) and a shaft (16). The power-shiftable multi-gear transmission (12) comprises at least one first gear stage (18) and one second gear stage (26) which are in each case configured as spur gear teeth. At least one first power transmission element is arranged on the input shaft (14) by means of a freewheel (21).
Power shift transmission for agricultural machines
A power shift transmission for an agricultural machine includes a transmission housing, an input shaft unit and an output shaft. The input shaft unit and the output shaft extend at least partially inside the housing. The transmission includes an auxiliary shaft arranged offset but parallel between the input shaft unit and the output shaft inside the housing. The input shaft unit and the auxiliary shaft are connected together via an upstream group, and the auxiliary shaft and the output shaft are connected together via a downstream group. Each of the upstream and downstream shift groups includes gearwheel pairs which may be individually selectively coupled. The input shaft unit includes an outer shaft and an inner shaft which is arranged coaxially in the outer shaft and which is rotatable relative to the outer shaft. The inner shaft and the outer shaft are connected together via a layshaft.
Multi-speed gearbox with a gear-clutch assembly
An electric drive axle of a vehicle includes an electric motor having an output shaft. A compound idler assembly is connected to the electric motor. The compound idler assembly includes at least one gear-clutch assembly in driving engagement with the output shaft of the electric motor. A differential is connected to the compound idler assembly, and in selective driving engagement with the compound idler assembly.
GEAR SHIFTING MECHANISM, TWO-SPEED GEARBOX, AND VEHICLE
This application provides a gear shifting mechanism, a two-speed gearbox, and a vehicle. The gear shifting mechanism includes a drive motor, a shifting drum, and a first shifting mechanism. The first shifting mechanism includes a first shifting fork, an inner shaft, an outer hub, a first coupling pin, and an elastic component. The elastic component is sleeved on the inner shaft and is located between the inner shaft and the outer hub. There are a first limiting portion and a second limiting portion between the outer hub and the inner shaft. The elastic component is located between the first limiting portion and the second limiting portion. The first limiting portion is connected to one of the outer hub and the inner shaft, and the second limiting portion is connected to the other of the outer hub and the inner shaft.
Power shift transmission with electric power assist
A power shift transmission includes an input shaft and a gear housing including a gear assembly disposed therein. The gear assembly is driven by the input shaft. The transmission also includes an output shaft rotated by the gear assembly. The transmission also includes an auxiliary shaft extending through a portion of the gear housing. The auxiliary shaft is rotated by an internal combustion engine. The transmission also includes a clutch assembly movable from a disengaged position to an engaged position. The clutch assembly includes a first clutch portion coupled to the input shaft and a second clutch portion coupled to the auxiliary shaft. The second clutch portion transmits rotational force to the first clutch portion only with the clutch assembly in the engaged position. The transmission also includes an electric motor including an electric motor shaft in geared relationship with the first clutch portion.
Power shiftable multi-gear transmission having freewheel
The invention relates to a power-shiftable multi-gear transmission (12) having a driven input shaft (14) and a shaft (16). The power-shiftable multi-gear transmission (12) comprises at least one first gear stage (18) and one second gear stage (26) which are in each case configured as spur gear teeth. At least one first power transmission element is arranged on the input shaft (14) by means of a freewheel (21).
HYDRAULIC SYSTEM AND METHOD FOR OPERATION OF SAID SYSTEM
Methods and systems for hydraulic actuation of axle system components are provided. A hydraulic system in an electric axle, is provided in one example, which includes a housing with a plurality of sections that enclose an electric motor and a gearbox, the system further includes a hydraulic pump that is coupled to the housing and configured to supply pressurized fluid to a solenoid valve through a plurality of fluid passages. The hydraulic system further includes a clutch in the gearbox configured to receive the pressurized fluid from the solenoid valve through a hydraulic passage internally routed through the housing.
TRANSMISSION, IN PARTICULAR FOR A VEHICLE
A transmission, such as a transmission for a vehicle, a driveline including the transmission, and a method of performing a gear shift using the transmission. The transmission comprises a first transmission shaft, a first gear disposed on the first transmission shaft, a first wet clutch, and a first synchronizer. The first wet clutch and the first synchronizer are configured to selectively drivingly engage the first gear with the first transmission shaft and are connectable in series between the first gear and the first transmission shaft, such that the first gear is drivingly engaged with the first transmission shaft only when both the first wet clutch and the first synchronizer are engaged, and such that the first gear is drivingly disengaged from the first transmission shaft when either one or both of the first wet clutch and the first synchronizer is/are disengaged.
