Actively controlled truck cab suspension

摘要

The system is provided for actively controlling the pitching of a truck cab. The system includes sensors and a single point hydraulic actuator mounted at the rear of the cab between the cab and the frame on which the cab is mounted which is computer controlled and activated in accordance with calculations provided by an algorithm programmed into the controller in response to cab or frame pitch acceleration signals received from the sensors. A feedback circuit is also provided which verifies activation of the actuator in accordance with the calculations provided by the algorithm being run in the controller.
