  • Patent number: 10690220
    Abstract: A mass damper system with a damper mass support receives a damper mass. A guide track and damper mass are in operative connection with one another by a coupling element movable in the guide track between a central position in which the coupling element is free from deflection in circumferential direction of the guide tracks and a deflection position out of the central position. The guide tracks and the coupling element are configured for an order that depends on the number of cylinders of the respective exciting drive. The guide tracks are tailored with respect to their geometric configuration for excitations of a virtual order between a first order associated with excitations of a drive with a first number of cylinders and a second order with which are associated with excitations of a drive with a second number of cylinders.

  • Patent number: 10690216
    Abstract: A control arrangement for a frequency-dependent damping valve having a control pot and an axaially displaceable control piston that axially limits a control space in the control pot and is connected to the damping valve device via an inlet connection. A spring element is arranged between the control piston and the damping valve that introduces a spring force axially into the control piston and the damping valve. When the control piston displaces towards the damping valve and the spring element increases the pressing pressure of the valve disks to increase the damping force. An axial position of a stop in the control arrangement is adjusted by plastic deformation of the pot base. A deformation portion produced by the plastic deformation and a depression partially receives the guide bush. A cross section of the depression corresponds to an outer cross section of the guide bush received in the depression.

  • Patent number: 10682909
    Abstract: A method of operating a drive-train of a vehicle having a drive engine, at least one drive axle and at least one further axle which can be drivingly connected by a pressure-controlled switching device. The switching device is acted upon by an opening pressure to disconnect the axle. When a service brake system of the vehicle is actuated, the axle is automatically connected by actuating the switching device, which is actuated as a function of a braking mode determined during actuation of the brake system, in such manner that when the brake system is actuated in a first braking mode, the switching device is actuated by a first control pressure to transmit a first torque, and if at least one parameter that characterizes the occurrence of a second braking mode is exceeded, the switching device is actuated by a second control pressure to transmit a second, higher torque.

  • Patent number: 10683009
    Abstract: A method for operating a drive train of a motor vehicle in an inclined position, in particular an agricultural or municipal utility vehicle. A connection between a prime mover and at least one drive axle of the motor vehicle is automatically disconnected as part of a function upon actuation of a service brake for stopping the motor vehicle monitored by at least one sensor. To avoid uncontrolled backward rolling, provision is made that a maximum brake pressure applied to achieve or maintain the standstill of the motor vehicle is determined and monitored by continually measuring a brake pressure applied by the service brake. Upon the brake pressure falling below the maximum brake pressure minus a pre-definable pressure difference, the function is automatically deactivated and thus the connection is automatically re-established between the prime mover and the at least one drive axle.

  • Patent number: 10668914
    Abstract: A method for operating a drive-train (1) of a motor vehicle having an internal combustion engine, a transmission connected between the internal combustion engine and a drive output, and a brake assembly. While the motor vehicle is traveling, if a manual command is given or if defined operating conditions exist, the drive-train (1) is operated in a coasting mode, in which the drive-train (1) is disengaged and the internal combustion engine is turned off. If the internal combustion engine, turned off for the coasting mode, fails to restart despite the existence of a signal to restart the internal combustion engine, a braking process is initiated automatically.
