A control device for an oscillating axle suspension, in particular a front axle suspension, includes at least of one hydraulic accumulator device (10), a suspension device (12) and a proportional valve (14) having a valve piston (26). The proportional valve (14) is connected to the accumulator and suspension devices (10, 12) via fluid ports (16, 18, 20, 22). The valve piston (26) is actuatable by an electric motor (28), is longitudinally guided in a valve housing (24) of the proportional valve (14) and controls the fluid ports (16, 18, 20, 22) such that, in at least one functional position of the valve piston (26), the axle oscillation is provided while the suspension is blocked and, in at least one further second functional position of the valve piston (26), the suspension is provided while the axle oscillation is blocked.

A wheel suspension for a vehicle with a supporting vehicle element includes at least one pair of single-sided swing arms. Each single-sided swing arm is associated with a hydraulic cylinder, which is linked to the single-sided swing arm and/or the supporting vehicle element. Each hydraulic cylinder is subdivided in a fluid-tight manner into two chambers.

A stabilizer includes a stabilizer bar, left and right cylinders, a parallel pipe, a cross pipe, a parallel on-off valve, and a valve controller. The parallel on-off valve maintains communication between a left side first fluid room of the left cylinder and a right side first fluid room of the right cylinder and maintains communication between a left side second fluid room of the left cylinder and a right side second fluid room of the right cylinder by opening itself. The parallel on-off valve cuts off the communication by closing itself. The valve controller switches an opening/closing state of the parallel on-off valve based on a running state of a vehicle or an operation state of the vehicle by a driver.
摘要:
Thermocouples and their associated thermocouple junctions can be integrated via freeform fabrication into various parts of injection-molding apparatuses, including the nozzles. Unitary monolithic integration of thermocouples allows thermocouple junctions to be located highly proximate to the locations where temperature monitoring is desired, particularly, near the tips of injection-molding nozzles, which has conventionally been difficult or impossible to achieve. An injection-molding nozzle with one or more integrated thermocouples, a hot-runner manifold with injection-molding nozzles, having integrated thermocouples, monolithically integrated with the manifold as a single part using a freeform fabrication process, and a separately formed injection-molding nozzle having at least one integrated thermocouple and a robust electrical connection are presented according to various aspects of the invention.

There is provided a vehicle comprising a chassis, two surface-engaging front wheels, at least one surface-engaging rear wheel and a propulsion unit for driving either the front wheels or the rear wheel or wheels. Each front wheel being connected to the chassis by means of a front wheel support assembly, wherein the front wheel support assembly comprises a hydraulic cylinder associated with each front wheel. Each hydraulic cylinder comprises a housing connected to one of the chassis and the front wheel support assembly, and a piston connected to the other of the front wheel support assembly and the chassis. The piston is moveable within the housing and arranged to divide the hydraulic cylinder into first and second chambers each having respective ports arranged to allow hydraulic fluid to enter and exit the respective chamber, the ports of the first chambers of each hydraulic cylinder being in fluid communication and the ports of the second chambers of each hydraulic cylinder being in fluid communication such that movement of hydraulic fluid from the first or second chamber of one hydraulic cylinder to the respective first or second chamber of the other hydraulic cylinder displaces the pistons of the hydraulic cylinders in opposing directions relative to the respective housings to enable the vehicle to tilt.

A damper assembly for a vehicle suspension system includes a primary damper and a secondary damper. The secondary damper includes a housing having a wall that at least partially surrounds at least a portion of the primary damper, the volume between the wall and the primary damper defining a chamber, and the wall defines an aperture. The secondary damper also includes a piston positioned within the chamber, a conduit defining a flow path that includes the aperture, and a valve disposed along the flow path. The primary damper is configured to provide a base damping force and the secondary damper is configured to provide a supplemental damping force that varies based on the position of the piston within the chamber.

A vehicle and a suspension system for the vehicle are disclosed. The suspension system includes a first suspension corner assembly adapted to support a structure of the vehicle and a second suspension corner assembly adapted to support the structure. The first suspension corner assembly includes a first bell crank and the second suspension corner assembly includes a second bell crank. The suspension system also includes an actuator device attached to the first and second bell cranks to selectively change at least one of a first spring rate and a preload.
摘要:
A system for varying an eyelet-to-eyelet distance of a vehicle. The system includes top and bottom mounting components defining the eyelet-to-eyelet distance, the top mounting component being operatively connected to a frame of the vehicle, and the bottom mounting component being operatively connected to a supporting component of the vehicle. The system also includes a telescopic component disposed about a housing of at least one of the top and bottom components, the telescopic component being displaceable with respect to said housing in response to a given input of a driver of the vehicle, for varying a distance between the top and mounting components, and thus varying the eyelet-to-eyelet distance of the vehicle. Also described is a vehicle including such a system, and a method of operating associated thereto.
