  • Publication number: 20160230818
    Abstract: A coupling for an AWD vehicle comprises a disc package with alternate discs (6,7; 56, 57; 76, 77), which are connected for rotation with, but are axially movable in relation to an ingoing (1; 52, 71) and an outgoing axle (2; 51; 72), respectively, of the coupling, and a hydraulic piston (9; 59; 79) for pressing the disc package together under the action of hydraulic pressure, hereby establishing a connect mode, in which the ingoing axle is connected to the outgoing axle. A coupling slack adjuster (13-15; 64, 65; 83-85) is provided for mechanically establishing a rest position for the hydraulic piston (9; 59; 79) in a disconnect mode, in which a predetermined slack in the disc package is established, irrespective of the wear of the discs.

  • Patent number: 9409588
    Abstract: A device adjusts the rotational damping of a steering device such that the rotational damping varies depending on whether the rotational motion about a steering axis is caused by a force acting on the steering device of the vehicle or a force acting on the part(s) of the vehicle contacting the ground. The flow of hydraulic fluid in the steering damper partly or wholly is adjusted by a main valve unit that is coupled together with both an attaching part and a steering device. The opening area of the main valve unit is determined by a relative motion between the attaching part and the steering device such that the flow of the hydraulic fluid in a direction from and to the respective damping chambers of the steering damper is controlled depending on the cause of the rotational movement.

  • Patent number: 9332570
    Abstract: A network node that serves a cell in a cellular communication system is operated. An air interface of the cellular communication system is divided up into sequentially occurring frames, each of the frames comprising a plurality of sequentially occurring sub-frames, each of the sub-frames comprising a plurality of sequentially occurring symbols. Operation includes receiving and detecting a request signal transmitted by a device within the cell. Based at least in part on a characteristic of the request signal that is indicative of one or more device capabilities of the device, an associated time/frequency position for transmitting a response signal is ascertained. The response signal is transmitted at the ascertained time/frequency position.

  • Publication number: 20150240935
    Abstract: A transfer case is provided with a primary shaft which is selectively engagable with a secondary shaft via a clutch mechanism. The clutch mechanism is inclusive of a friction pack. A hub of the clutch mechanism is connected on the primary shaft and the clutch housing is torsionally fixed with a primary sprocket rotatively mounted on the primary shaft. A passive or active controlled lubricant collection receptacle is provided which maximize fluid retention in conditions wherein there is not a high demand of torque for the clutch system of the transfer case thereby minimizing fluid that is unnecessarily churned by engagement with the hub connected with the secondary shaft.

  • Publication number: 20150236804
    Abstract: A user equipment (UE) in a cellular telecommunications system is able to detect the uplink/downlink configuration of a detected neighboring cell by receiving a signal from the neighboring cell. A characteristic of the received signal is detected and used as an indicator in a blind detection process to identify one or more downlink slots in the received signal. Known pilot signals in the identified one or more downlink slots can then be used to obtain a signal power measurement of the received signal. The blind detection process is also capable of detecting whether a slot of a neighboring cell's signal is a downlink unicast slot or a Multicast-Broadcast Single Frequency Network slot.
