  • Patent number: 10962521
    Abstract: A condition monitoring system that determines a presence of change of water content in grease. The system provides a sensor electrode that is placed in the space where the grease is located. The electrode is suitably a plate with a surface area creating a capacitance C. This in combination with a resistor R, creates an RC circuit. The system senses the RC circuit. The dielectric constant of the monitored grease varies in dependence of the water content of the grease. A change of the dielectric constant will change RC, that is then sensed by the system. An analysis of a change of RC will determine if there is a presence of a change of the level of water content in the monitored grease.

  • Patent number: 6868751
    Abstract: A parking brake including a lever (3) coupled to a brake wire (9) included in the brake system. The lever (3) is arranged to work in two steps to achieve the desired braking power. In the first step the lever is arranged to make a translational movement for taking up wire slack in the brake system, while in the second step the lever is arranged to execute a rotation whereby the force transmission to the wire (9) takes place at a higher ratio than in the first step.
