Embodiment Construction

[0104] A clutch-controlled or "disengageable" transfer case 01 according to the invention as in particular in figure 1 As can be seen in , it comprises the housing 3 surrounding the housing interior 02 and essentially the following components 11, 12, 13, 14, 15:

[0105] - a first assembly 11 comprising a drive shaft 04 mounted rotatably in the housing 03 and / or relative to at least a part of at least one further assembly 12 , 13 , 14 , 15 by means of at least one drive shaft bearing 40 ,

[0106] - a second assembly 12 comprising at least one part permanently coupled to the drive shaft 04 and rotatable in the housing 03 and / or relative to at least one further assembly 11 , 13 , 14 , 15 by means of at least one spindle bearing 50 ground mounted spindle 05,

[0107] - a third assembly 13 comprising at least a part arranged axially offset from the drive shaft 04 and in the housing 03 and / or relative to at least one further assembly 11 , 12 , 14 , 15 by means of at least one cou...

Abstract

A clutch-controlled transfer gear having a drive shaft which is mounted so as to be rotatable by way of at least one drive shaft bearing, a primary shaft which is mounted so as to be rotatable by way of at least one primary shaft bearing, a secondary shaft which is arranged with an axial offset with respect to the drive shaft and which is mounted so as to be rotatable by way of at least one secondary shaft bearing, a transfer mechanism which is arranged between secondary shaft and drive shaft and bridges the axial offset thereof, and a clutch which is arranged between the drive shaft and an offset gear, by means of which clutch the secondary shaft is, for the operation thereof, coupled to the drive shaft and, for the deactivation thereof, decoupled from the drive shaft, as required.

Description

technical field [0001] The invention relates to a clutch-controlled transfer case. Background technique [0002] Transfer cases are used in particular in motor vehicles with all-wheel drive in order to distribute the torque generated by the engine and provided on the drive shaft of the transfer case to the two output shafts of the transfer case and thus to more than A driven axle. In this case, each output shaft drives an axle of the motor vehicle or—if the motor vehicle has more than two driven axles—an axle drive by means of a direct gear drive. [0003] Along the flow of power from the engine to the driven axles, the transfer case is usually arranged downstream of the main transmission of the drive motor for transmitting the torque generated by the drive motor. [0004] A distinction is made between transfer cases based on their construction type, so-called differential-controlled transfer cases, and clutch-controlled transfer cases. In differentially controlled transf...
