A retarder system for commercial vehicles is provided which consists of a transmission oil circuit ( ) for lubrication of the transmission and of a retarder cooling circuit ( ) which uses oil as operating fluid, both circuits being coupled via a connection ( ) so that in the non-activated braking state of the retarder ( ), for increasing the transmission oil flow rate through a radiator ( ), oil can be branched off from the transmission oil circuit ( ). In addition a retarder pump ( ) is proposed which has a prime mover ( ), preferably an electrical motor.

Retarder system

An all-wheel distributor transmission ( ) is described for a motor vehicle comprising a planetary gear set as multiplication step ( ) for a switchable off-road gear and a planetary gear set ( ) with variable division for distributing a drive torque onto a front axle and a rear axle. The all-wheel distributor transmission ( ) also has an adjustable lock ( ) for locking between the front axle and the rear axle, the lock ( ) and the multiplication step ( ) being actuatable via a controllable drive device ( ). The drive device ( ) comprises a drive shaft ( ) and two output shafts ( ), the first output shaft ( ) being in operative connection with the multiplication step ( ) and the second output shaft ( ) being in operative connection with the lock ( ). A torque introduced via the drive shaft ( ) can be applied on the first or the second output shaft ( or ) according to a control of a shift unit ( ) for actuating the lock ( ) or the multiplication step ( ).

All-wheel distributor gearbox for a motor vehicle

A device for the suspension and for roll stabilization of motor vehicles achieves the required roll stiffness as well as the required lift stiffness without any additional springs by coordinating the ratio of the piston areas to the piston ring areas of the spring cylinders with simultaneous active engagement by an actuator integrated between the cross-wired lines.
