A vehicle air suspension installation includes pneumatics configured for operation in conjunction with a compressed air supply installation, and comprises: a pneumatic line having a port connection to the air supply installation, air bellows, each serving as a pressure chamber for an air spring, one air bellows being connected to the pneumatic line via a directional solenoid valve, and the air bellows being fillable/bleedable depending on a switching state of the valve, and first and second directional valves forming a solenoid valve system, which has a pneumatic part that is actuatable by a magnetic part. The first directional valve forms a primary valve, and the second forms a secondary valve. First and second air bellows associated with the valve system are fillable/bleedable depending on the switching state of the primary and secondary valves. The primary and secondary valves are controllable by a controller of the magnetic part. The controller is common to and acts upon both valves.

An air management system for a vehicle having a first pneumatic circuit and a second pneumatic circuit, in which the first and second pneumatic circuits are pneumatically connected in a neutral position via a cross-flow mechanism. The first pneumatic circuit is configured to independently adjust air pressure of a first side of the vehicle. The second pneumatic circuit is configured to independently adjust air pressure of a second side of the vehicle. The system is configured to establish pneumatic communication between the first and second pneumatic circuits when the air management system is not independently adjusting the adjust air pressure of the first side of the vehicle and the air pressure of the second side of the vehicle in the cross-flow mode.

A device, system, and method for leveling a load may be provided. The system may utilize load sensors to monitor the weight allocation of a load in a vehicle or trailer. The system may further include air bag suspension configured to inflate or deflate based on the weight allocation. The air bag suspension may use at least one compressed air tank, actuator, and dump valve. A computer control module may receive all of the data from the load sensors, calculate the adjustments to the suspension necessary to level the load or compensate for shifts in the load.

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 vehicle includes a chassis, a plurality of tractive assemblies coupled to the chassis, and a controller. Each tractive assembly includes a tractive element and an actuator coupled to the tractive element and configured to move the tractive element relative to the chassis. The controller is configured to control at least one of the actuators to vary a load supported by one of the tractive assemblies in response to an indication that a portion of a first tractive assembly of the plurality of tractive assemblies is disabled.

A dryer circuit for a pneumatic regulating device of a vehicle, comprising an air dryer, and a first compressor, wherein the first compressor is designed to compress system air present in the pneumatic regulating device, wherein the air dryer, the first compressor and subsystems, which can be connected to the first compressor, of the pneumatic regulating device are arranged in such a way that, in the operating mode of a closed air supply, air delivered between the components of one of the subsystems by the first compressor is delivered so as to bypass the air dryer.

A method of controlling a suspension system of a vehicle includes identifying an amplitude and a frequency of at least one harmonic event in a topology of a surface to be traversed by the vehicle, and, with a controller, altering at least one response characteristic of at least one adjustable component of the suspension system based on at least one of the amplitude and frequency of the harmonic event. Systems and methods relate to controlling vehicle suspension systems.

A vehicle linear motor includes: a tubular casing; a pair of armatures placed and fixed in the casing; a mover formed in a flat plate shape and placed to face the pair of armatures and to be movable in the casing; and a support member configured to slidably support the mover such that the mover moves in a longitudinal direction of the mover. The mover formed in the flat plate shape includes a plurality of magnets that are arranged at intervals in the longitudinal direction. Each of the pair of armatures has a magnetic pole that is arranged to move the mover relative to the armatures in the longitudinal direction. The casing is mounted on a vehicle such that the longitudinal direction is a horizontal direction, and the mover and the armatures are placed to face each other in the horizontal direction.

A shock-absorbing front fork assembly of a motorcycle includes a front fork, a pressure buffering cylinder and a control valve disposed between the front fork and the pressure buffering cylinder and electrically connected with a brake system to control the communication between the front fork and the pressure buffering cylinder according to the operation of the brake system. When the brake system is not actuated, the control valve is open to make the front fork communicate with the pressure buffering cylinder, thereby making the spring supporting force relatively smaller. When the brake system is actuated, the control valve is close to make the front fork not communicate with the pressure buffering cylinder, thereby making the spring supporting force relatively larger. Therefore, the spring supporting force is adjusted by the brake operation, that raises the riding comfort and safety.

A weight estimation device for a vehicle includes a storage unit storing a weight calculation information indicating a correspondence between an internal pressure value of an air spring supporting a vehicle body and a vehicle height serving as a height of the vehicle body from a base, a measured value acquisition unit acquiring a measured internal pressure value and a measured vehicle height, an internal pressure value calculation unit calculating a corrected internal pressure value of the air spring by deducting or adding a corrected value from or to the measured internal pressure value in a case where the measured internal pressure value is greater or smaller than the internal pressure value of the weight calculation information which corresponds to the measured vehicle height, and a weight calculation unit calculating a weight of a supported body, including the vehicle body, based on the corrected internal pressure value.
