Abstract
A transfer case for transferring a driving torque of a driving unit of a motor vehicle to a first axle and a second axle of the motor vehicle. The transfer case includes a housing, an input shaft allocated to the driving unit, a first driven shaft allocated to the first axle, and a second driven shaft allocated to the second axle and offset parallel to the input shaft. The transfer case further includes an offset drive for transmitting driving torque from the input shaft to the second driven shaft. The offset drive comprises a gear wheel coaxial to the input shaft or to the driven shaft. The gear wheel is rotatably mounted on a section of the housing.
Claims21
A transfer case for transferring a driving torque of a driving unit of a motor vehicle to a first axle and a second axle of the motor vehicle, the transfer case comprising:
- an input shaft allocated to the driving unit;
- a first driven shaft allocated to the first axle, and a second driven shaft allocated to the second axle and which is offset parallel to the input shaft;
- a housing configured to rotatably support each of the input shaft and the first and second driven shafts, the housing having a mounting collar defining an aperture and a tubular extension extending axially from the mounting collar, wherein the input shaft extends through the aperture in the mounting collar and at least a portion of at least one of the input shaft and the first driven shaft is coaxially surrounded by the tubular extension;
- and
- an offset drive coupled for rotation with the second driven shaft, wherein the offset drive comprises a gear wheel rotatably mounted on the extension.
A powertrain having a transfer case for transferring a driving torque of a driving unit of a motor vehicle to a first axle and a second axle, the transfer case comprises a housing, an input shaft allocated to the driving unit, a first driven shaft allocated to the first axle, a second driven shaft allocated to the second axle and which is offset parallel to the input shaft, an offset drive for transmitting driving torque from the input shaft or the first driven shaft to the second driven shaft and having a gear wheel coaxial to the input shaft or to the first driven shaft and being rotatably mounted on a section of the housing, and a clutch unit by means of which the second driven shaft can be supplied selectively with driving torque, and wherein the powertrain comprises a clutch which is arranged between the clutch unit of the transfer case and at least one wheel of the motor vehicle and the purpose of which is to deactivate a section of the powertrain situated between the clutch unit and the clutch.
A transfer case for transferring a driving torque of a driving unit of a motor vehicle to a first axle and a second axle, the transfer case comprising:
- a housing having a mounting collar section defining an aperture;
- an input shaft adapted to receive the driving torque from the driving unit and which extends through said aperture in said mounting collar section of said housing;
- a bearing for rotatably mounting said input shaft within said aperture;
- a first output shaft adapted for connection to the first axle;
- a second output shaft adapted for connection to the second axle;
- a tubular extension extending axially from said mounting collar section and coaxially surrounding at least a portion of at least one of said input shaft and said first output shaft;
- and
- an offset drive coupled for rotation with said second output shaft and including a gear wheel coaxially surrounding said extension.
A transfer case for use in a motor vehicle to transfer a driving torque from a driving unit to first and second axles, comprising:
- an input shaft aligned for rotation about a first rotary axis and adapted for connection to the driving unit;
- a first output shaft aligned for rotation about said first rotary axis and adapted for connection to the first axle;
- a second output shaft aligned for rotation about a second rotary axis and adapted for connection to the second axle, said second rotary axis being offset relative to said first rotary axis;
- a housing configured to rotatably support said input shaft and said first and second output shafts, said housing having a mounting collar defining an aperture and a tubular extension extending axially relative to said mounting collar, wherein said input shaft extends through said aperture in said mounting collar;
- and
- an offset drive for transmitting driving torque from said input shaft to said second output shaft, said offset drive including a first rotary component that is drivingly coupled to a second rotary component fixed for rotation with said second output shaft, wherein said first rotary component is rotatably mounted on said tubular extension which is secured to or formed integrally with said housing, and wherein at least one of said input shaft and said first output shaft coaxially extends through an aperture formed in said extension.
