20100147641 | COOLING SYSTEM WITH A DRIVE MOTOR AND A HYDRODYNAMIC MACHINE - A cooling system has a drive motor which is to be cooled by a cooling medium. A cooling medium circuit conducts the cooling medium. A hydrodynamic machine comprising a working space can be filled with a working medium. The working medium is the cooling medium, and the hydrodynamic machine has a seal which is cooled and/or lubricated by the cooling medium. A cooling medium pump for circulating the cooling medium is in the cooling medium circuit. A pick-off is in the cooling medium circuit in the region of the cooling medium pump. Via the pick-off, the cooling medium is branched out of the cooling medium circuit. The branched-off cooling medium is conducted directly through or past the seal to cool and/or lubricate the latter, and the cooling medium which is conducted through or past the seal is supplied to the cooling medium circuit upstream or downstream of the working space. | 06-17-2010 |
20120222927 | COOLER FOR A SUSPENSION DAMPER - A method and apparatus are disclosed for cooling damping fluid in a vehicle suspension damper unit. A damping unit includes a piston mounted in a fluid cylinder. A bypass fluid circuit having an integrated cooling assembly disposed therein is fluidly coupled to the fluid cylinder at axial locations that, at least at one point in the piston stroke, are located on opposite sides of the piston. The cooling assembly may include a cylinder having cooling fins thermally coupled to an exterior surface of the cylinder and made of a thermally conductive material. The bypass channel may include a check valve that permits fluid flow in only one direction through the bypass channel. The check valve may be remotely operated, either manually or automatically by an electronic controller. A vehicle suspension system may implement one or more damper units throughout the vehicle, controlled separately or collectively, automatically or manually. | 09-06-2012 |
20140131153 | Hydrodynamic Retarder and Method for Controlling the Power Transmission of Such a Retarder - The invention concerns a method for controlling the power transmission of a hydrodynamic retarder, comprising a rotating bladed rotor and a bladed stator or a bladed counter-rotor rotating against the direction of rotation of the rotor, which form together a working chamber which selectively can be filled with a working medium via an inlet and can be drained via an outlet; whereas the working chamber is filled with a working medium in braking mode, and a braking torque is generated with the hydrodynamic retarder and in a non-braking mode the working chamber is emptied of working medium down to a certain residual amount and substantially no braking torque is generated with the hydrodynamic retarder. The invention is characterised by the following step: In non-braking mode, working medium is injected into the working chamber of the hydrodynamic retarder for adjusting the residual amount, said working medium being extracted from a stock of working medium, which is provided outside the working chamber in a working medium storage tank using an idle pump. | 05-15-2014 |

20140305755 | ELASTOMERIC DAMPER WITH HEATER - A damper system includes a damper and a heater operably associated with the damper. The method includes heating the damper with heat energy from the heater and then monitoring and regulating the heat energy to the damper with a sensor and control subsystem. | 10-16-2014 |
20150090547 | METHODS AND APPARATUS FOR SUSPENSION LOCK OUT AND SIGNAL GENERATION - Methods and apparatus for regulating the function of a suspension system are disclosed herein. Suspension characteristics often contribute to the efficiency of a suspended system. Depending on the desired operating parameters of the suspended system, it may be desirable to alter the functional characteristics of the suspension from time to time in order to maintain or increase efficiency. The suspension hereof may be selectively locked into a substantially rigid configuration, and the damping fluid may be phase separated and/or cooled to increase damping rate during use (or offset rate degradation). The suspension hereof may generate power usable to achieve any or all of the foregoing or to be stored for use elsewhere in the suspended system or beyond. | 04-02-2015 |
