摘要

#CMT# #/CMT# The differential gear has a drive unit (12) rotatably connected with a pinion cage (21), and two power take-off units (13, 14). A mechanical coupling device (10) connects the drive unit with the power take-off units and has mechanical locking units (15-18) arranged in row. The coupling device is locked based on rotation speed and one of the power take-off units. The power take-off units is locked below a marginal rotation speed of the drive unit. #CMT# : #/CMT# An independent claim is also included for a method for a coupling device. #CMT#USE : #/CMT# Spur wheel differential gear. #CMT#ADVANTAGE : #/CMT# The mechanical coupling device connects the drive unit with the power take-off units, thus realizing drive torque distribution for different drive wheels in different road conditions. The mechanical locking units are arranged in row, thus achieving high flexibility and locking characteristics of the coupling device in a simple manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a sectional view of a spur wheel differential gear with a coupling device. 10 : Coupling device 12 : Drive unit 13, 14 : Power take-off units 15-18 : Locking units 21 : Pinion cage.
