An apparatus for estimating vehicle weight using a vehicle height adjusting device is provided. The apparatus includes a vehicle height adjusting device that raises or lowers four positions of front left (FL) and right (FR) sides and rear left (RL) and right (RR) sides of a vehicle body, respectively. A vehicle height controller operates the vehicle height adjusting device to raise or lower the FL and FR sides and the RL and RR sides of the vehicle body. A weight estimating unit measures time required for raising or lowering the vehicle body or operating speed of the vehicle body and calculates an expected vehicle weight value by comparing the time required or the operating speed with a preset reference data.

Example illustrations are directed to a suspension system for a vehicle and methods. In some examples, a controller of a suspension system is configured to determine the vehicle is in a service environment, and to set a height precision mode for the suspension system based on the determination the vehicle is in the service environment. In some examples, the controller is configured to detect a suspension operating condition of the vehicle, and to change a setting associated with the suspension system based on the suspension operating condition. An example method comprises detecting, using a controller, a suspension operating condition of a suspension system of a vehicle. The method may further include changing, using the controller, a setting associated with the suspension system based upon the suspension operating condition.

An apparatus for adjusting a height of a vehicle including a vehicle height adjustment unit configured to adjust a height of the vehicle; a hydraulic pressure supply unit configured to supply a hydraulic pressure supplied to a caliper from a braking device for braking of the vehicle to the vehicle height adjustment unit; and a control unit configured to control a hydraulic pressure supplied to the vehicle height adjustment unit from the braking device, by controlling the hydraulic pressure supply unit depending on whether a predetermined vehicle height adjustment condition is satisfied.

An air suspension system, comprising a manifold, defining a first and second port, each port defining a receiving region at the second end, wherein the first and second ports are arranged in a common plane, a channel intersecting the first and second port, a cavity intersecting each port, and a pressure sensor port, positioned between the first and second port, defining a sensor insertion axis normal to the common plane, the pressure sensor port separated from the first port, the second port, and the channel by a thickness; a first and second solenoid valve, each solenoid valve arranged within the cavity and coaxially arranged with the first and second ports, each solenoid valve comprising a connector; a pressure sensor arranged within the pressure sensor port, the pressure sensor comprising a connector; and an electronics module arranged parallel the common plane, the electronics module configured to electrically couple to the connectors.

A damper valve with an adjustable effective stiffness of a shim. The damper valve includes a piston. The piston has a fluid path formed therethrough. A shim is disposed proximate the fluid path formed through the piston. A stiffness adjustment feature is coupled to the shim, and the shim is disposed between the piston and the stiffness adjustment feature. The stiffness adjustment feature is configured to adjust the effective stiffness of the shim without affecting a preload applied to the shim.

A vehicle is provided which has a vehicle body, at least one hub of a wheel, and a suspension connecting the hub to the vehicle body. The suspension has a suspension arm hinged to the vehicle body and to the hub, a spring, and an electromechanical rotary actuator operable between an active adjustment condition and a damping condition of the motion of the suspension, via a leverage.

An electric drive system including: a rotary motor system including a hub assembly, a first rotating assembly, a second rotating assembly, and a third rotating assembly, wherein the hub assembly defines a rotational axis about which the first rotating assembly, the second rotating assembly, and the third rotating assembly are coaxially aligned and are capable of independent rotational movement independent of each other; a multi-bar linkage mechanism connected to each of the first and third rotating assemblies and connected to the hub assembly and constraining movement of the hub assembly so that the rotational axis of the hub assembly moves along a defined path that is in a transverse direction relative to the rotational axis and wherein the multi-bar linkage mechanism causes the rotational axis of the hub assembly to translate along the defined path in response to relative rotation of the first rotating assembly and the third rotating assembly with respect to each other.

A shock damper is disposed between a vehicle body side and a wheel side. A suspension control device calculates a damping force of the shock damper on the basis of vehicle height information and controls the damping force. A steering system includes an electric motor and a steering control device that controls the electric motor, and assists steering effort of the driver through the electric motor. The suspension control device calculates the vibration generated in a steering on the basis of a detected value of a vehicle height sensor and creates a signal for generating steering torque that reduces the generated vibration. The suspension control device outputs the created signal to the steering control device. Steering torque for cancelling steering vibration is accordingly outputted from the electric motor of the steering system.

A trailer system for hauling material. The trailer system including a frame and a container attached to the frame. A lid is operatively associated with a first aperture and adapted to at least move between an open position and a closed position. When in the closed position the lid seals the first aperture such that the seal is watertight. A gate is operatively associated with a second aperture and adapted to at least move between an open position and a closed position. When in the closed position the gate seals the second aperture such that the seal is watertight. A pusher plate assembly is arranged with the container for pushing material contained in the container in a direction towards the second aperture.
