Embodiment Construction

[0092] exist figure 1 Neutralize in figure 2 The device 01 shown in full or in part for actuating a clutch-controlled transfer case with a two-stage intermediate transmission comprises:

[0093] - a shift shaft 02 preferably rotatably driven in opposite directions of rotation,

[0094] - a drive, preferably an electric motor, for rotating the shifting shaft 02 , wherein however other drives are also conceivable, for example hydraulic or pneumatic drives to name only a few conceivable designs, or combinations of these drives;

[0095] - the clutch cam disc 03 and possibly the shift cam disc, both of which can be rotated by means of the shift shaft 02 about their own axis or about a common axis, for example the same axis as the shift shaft 02 , or both One of them is rotatable about the axis of the shift shaft 02 and the other of them is rotatable about its own axis; and

[0096] - one or two scissor levers 05 coupled to the actuating mechanism 04 for actuating the friction ...

Abstract

A device for actuating a clutch-controlled transfer case including a rotatable selector shaft, a clutch cam disk rotatable about a clutch cam disk axis by means of the selector shaft and having a gate, and at least one scissor lever having an end guided in the gate. The gate has at least one curved portion having a continuously increasing radial distance from the clutch cam disk axis. The clutch cam disk defines an opening about the clutch cam disc axis, and the clutch cam disk defines a pair of stops extending radially into the opening. The selector shaft is rotatably positioned in the opening. The selector shaft includes a stopping member in radial alignment with the pair of stops such that the selector shaft can be rotated with respect to the clutch cam disk between two stops.

Description

technical field [0001] The invention relates to a device and a clutch-controlled transfer case. Background technique [0002] Transfer cases are commonly used 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 driven shafts of the transfer case to more than one driven axle. In this case, each of the output shafts drives an axle of the motor vehicle or—if the motor vehicle has more than two driven axles—drives an axle drive with a direct drive. [0003] Along the line of force from the engine to the driven axles, the transfer case is usually mounted downstream of the vehicle transmission for transmitting the torque produced by the engine. [0004] For example, for use in off-road vehicles and / or in heavy-duty tractors, in addition to multi-wheel drive and / or all-wheel drive by means of a transfer case, there is a two-stage intermediate drive, also called off-road re...
