摘要： A linear energy harvesting device that includes a housing and a piston that moves at least partially through the housing when it is compressed or extended from a rest position. When the piston moves, hydraulic fluid is pressurized and drives a hydraulic motor. The hydraulic motor drives an electric generator that produces electricity. Both the motor and generator are central to the device housing. Exemplary configurations are disclosed such as monotube, twin-tube, tri-tube and rotary based designs that each incorporates an integrated energy harvesting apparatus. By varying the electrical characteristics on an internal generator, the kinematic characteristics of the energy harvesting apparatus can be dynamically altered. In another mode, the apparatus can be used as an actuator to create linear movement. Applications include vehicle suspension systems (to act as the primary damper component), railcar bogie dampers, or industrial applications such as machinery dampers and wave energy harvesters, and electro-hydraulic actuators.

摘要： Self-steering axle assembly has an axle with central tube having a longitudinal central axis. A king pin is connected with an end portion of the axle. A knuckle is connected with the king pin. The knuckle includes a torque plate section. A first arm of the knuckle extends from a side of the torque plate section and receives a first end portion of the king pin. A second arm extends from the torque plate section in the same direction as the first arm. The second arm receives a second end portion of the king pin. A spindle is friction welded to the torque plate section and has a longitudinal central axis. The torque plate section has at least one surface on the torque plate section extending substantially perpendicular to the longitudinal central axis of the spindle. A tool engages the surface during friction welding of the spindle to the torque plate section. The relative locations of the axle, spindle and king pin enable an air disc brake actuator to avoid contact with components of the heavy-duty vehicle during steering and with the ground and debris.
