A communication system for a vehicle comprises a mechanism for sensing a motion status of a vehicle, a control device, plurality of data acquisition sensors, and one or more alerting device activation circuits. The communication system is customizable with the plurality of data acquisition sensors and one or more alerting device activation circuits based upon the needs of the vehicle.

A machine includes a first cylinder coupled to a first wheel and a second cylinder coupled to a second wheel. A first proportional dampening valve fluidly connects to the first cylinder and a second proportional dampening valve fluidly connects to the second cylinder. First accumulators are fluidly connected to the first cylinder and the first proportional dampening valve, and second accumulator(s) are fluidly connected to the second cylinder and the second proportional dampening valve. Additionally, a first proportional flow control valve fluidly connects to the first cylinder and a second proportional flow control valve fluidly connected to the second cylinder. An electronic control module (ECM) communicatively couples to the first proportional flow control valve and the second proportional flow control valve to adjust a ride height of the first wheel via the first cylinder and a ride height of the second wheel via the second cylinder.

A rocking arm structure includes an arm body, a motive wheel assembly connected to the arm body, a caster wheel assembly connected to the arm body, and a shaft assembly connected to the arm body and disposed between the motive wheel assembly and the caster wheel assembly. The two wheel assemblies are configured to revolve in a same direction around the shaft assembly and for example allow a 4-wheeled vehicle/robot to become a 6-wheeled vehicle for stability as required during changes of terrain.

An active control system for vehicle suspensions includes a detection module which detects a vehicle running state and a front road condition by means of an advanced mode or a standard mode; a calculation module which comprehensively calculates, in combination with running data and dimensions of a vehicle and the front road condition data collected by the detection module and according to passenger comfort requirements, target data of adjustment; and an implementation module which adjusts a height of each suspension of the vehicle according to the target data obtained by the calculation module.

A multi-axle transport trailer having a plurality of axles includes a suspension comprising air bags associated with each axle, the air bags in communication with an air source, wherein air bags associated with different axles are capable of having different air pressures therein. The trailer further optionally includes a steering system associated with at least one axle, the axle including a tie rod connected between wheels on both ends of the axle, the steering system comprising cylinders configured to articulate the wheels, and a sensing device configured to monitor movement of the tie rod and facilitate actuating the cylinders to turn the wheels.

A hydraulic level-adjustment device has a reservoir, a reversible hydraulic unit with a hydraulic pump, and a single-acting hydraulic linear actuator. To lift a vehicle chassis, the working space of the linear actuator can be pressurized by the hydraulic pump operated in its first pumping direction via its first pump connection and a fill line with a fill-check valve arranged therein. To lower the chassis, via its second pump connection, the hydraulic pump, operated in the reverse pumping direction, pumps hydraulic fluid into the reservoir via an outflow line with a throttle unit arranged therein. The pressure present upstream of the throttle unit acts on the control connection of a lockable, drainage-check valve via a control line and opens same, so that, under the weight of the motor vehicle, hydraulic fluid is forced out of the working space of the hydraulic linear actuator into the reservoir via the drainage line.

A vehicle includes a chassis, an axle, and a sway bar assembly coupled between the chassis and the axle. At least one actuator is configured to move the sway bar assembly relative to the axle to thereby move at least a portion of the chassis toward or away from the axle to adjust an attitude of the vehicle.

The present disclosure relates to an apparatus and method for controlling a lift axle of a vehicle. To assist with braking according to an operation of a forward collision avoidance (FCA) system by using the lift axle in an emergency braking situation, the vehicle lift axle control apparatus includes a lift axle actuator that drives the lift axle of the vehicle, an interworking device that interworks with the FCA system, and a controller that controls the lift axle actuator based on information obtained from the FCA system.

Disclosed embodiments are related to suspension systems including dampers and suspension actuators and related methods of control for mitigating the effects of potholes and other road surface discontinuities.

A spur gear includes an input wheel, an output wheel, and an intermediate wheel, which engages via a gear with a gear on the input wheel and with a gear on the output wheel. A blocking mechanism is provided on the intermediate wheel which, in a first operating state, permits the transmission of torque from the input wheel to the output wheel and, in a second operating state, blocks the transmission of torque from the input wheel to the output wheel. At least one guide track for the blocking mechanism is formed on the intermediate wheel, the guide track having a radially inner guide wall and a radially outer guide wall. A latching position for blocking the blocking mechanism is formed on the radially outer guide wall.
