20160001765 | METHODS, SYSTEMS, AND VEHICLES WITH ELECTROMECHANICAL VARIABLE TRANSMISSION - A method of operating a first motor/generator and a second motor/generator in a vehicle drive includes operating the vehicle drive in a first operating mode and a second operating mode, the first operating mode including operating the first motor/generator as a generator and operating the second motor/generator as a motor, the second operating mode including operating both the first motor/generator as a generator and the second motor/generator as a generator when a first power generation capability associated with the first motor/generator is below a first threshold level, the first motor/generator and the second motor/generator providing electrical power to the DC bus without doing either of (a) providing electrical power to an energy storage device or (b) consuming electrical power from an energy storage device. | 01-07-2016 |
20150377314 | DAMPER ASSEMBLY - A damper assembly includes a tubular member, an outer cylinder positioned at least partially within the tubular member, an inner cylinder positioned at least partially within the outer cylinder, a cap coupled to the inner cylinder, a plunger received within the inner cylinder and coupled to an end of a rod extending at least partially within the inner cylinder, an annular piston fixed to the inner cylinder where the annular piston extends between the inner cylinder and the outer cylinder, and a barrier extending between the inner cylinder and the outer cylinder. The rod has an outer diameter that is smaller than an inner diameter of the inner cylinder. The plunger, the cap, and an interior of the inner cylinder at least partially define a first chamber. The barrier, the annular piston, an exterior surface of the inner cylinder, and the outer cylinder at least partially define a second chamber. | 12-31-2015 |
20150290993 | SUSPENSION ELEMENT - A suspension element includes a main body having an internal volume configured to contain a liquid therein, a tubular element extending at least partially within the main body, the tubular element having an internal volume that defines a first fluid chamber configured to contain a compressible gas therein, a first piston separating the internal volume of the main body into a second fluid chamber and a third fluid chamber, a second piston positioned to separate the first fluid chamber from the second fluid chamber, and a flow control element disposed along a flow path between the second fluid chamber and the third fluid chamber. Movement of the tubular element generates a flow of the liquid through the flow control element to produce a damping force and changes the pressure of the compressible gas to produce a spring force. | 10-15-2015 |
20150224847 | CO-AXIAL SWAY BAR FOR A SUSPENSION SYSTEM - A suspension system for a vehicle having a frame includes a first interface member configured to be positioned on a first lateral side of the frame and a second interface member configured to be positioned on an opposing second lateral side of the frame. The first interface member and the second interface member are positioned along a common central axis. The suspension system also includes a first swing arm coupled to the first interface member and configured to rotate about the common central axis, a second swing arm coupled to the second interface member and configured to rotate about the common central axis, and a sway bar coupled to the first interface member and the second interface member. The sway bar is positioned coaxially with the common central axis and extends between the first swing arm and the second swing arm. | 08-13-2015 |
20150197129 | GAS SPRING ASSEMBLY FOR A VEHICLE SUSPENSION SYSTEM - A gas spring for a vehicle suspension system includes a cylinder, a rod disposed within the cylinder, the rod and the cylinder defining a chamber, and an accumulator in communication with the chamber. The rod and the cylinder are configured such that a relative movement therebetween changes the volume of the chamber. Gas in the chamber and the accumulator are configured to cooperate to at least partially provide a spring rate that varies based on at least one of a deflection and a spring force associated with at least one of the rod and the cylinder. | 07-16-2015 |
