    摘要: An automatic stability control system is provided which senses the lateral acceleration of a vehicle by way of strain gauge sensors, or the like, to provide lateral acceleration signals to an amplifier. Since strain gauge sensors which operate on the piezoelectric effect provide very weak signals, special amplifier circuits must be employed. The amplified signals control a brake assembly on the vehicle to simultaneously, continuously and gradually apply the right and left brakes with a force proportional to the lateral acceleration signals in order to eliminate swerving or swaying of the vehicle. The amplifier is mounted in the vehicle and includes a sensitivity adjustment for setting a threshold point corresponding to a minimum lateral acceleration force to which the system will respond. Sensor configurations are also used which have strain gauges to sense the regular brake fluid pressure of the vehicle in combination with the lateral force sensing sensors. Additional sensitivity adjustments are provided for the amplifiers of these configurations. The control system is primarily adapted for use in a trailing or towed vehicle in combination with a leading or towing vehicle although it is equally effective when used in a single vehicle.

    摘要: A vehicle suspension includes a dock height holding device. First and second jounce bumper portions preferably each include a surface configuration that faces generally toward the oppositely facing jounce bumper portion. By moving at least one of the jounce bumper portions between first and second alignment positions, the clearance between suspension components is controlled in a manner that controls the height of a truck bed or trailer deck. In one example, each jounce bumper portion includes four projections and four spaced recesses. In the first alignment position the projections on one jounce bumper portion are received within the recesses on the oppositely facing portion during normal driving conditions. In the second alignment position, the projections of the jounce bumper portions engage each other and maintain a larger clearance between the suspension components to ensure an appropriate deck height when the vehicle is parked for loading or unloading.

    摘要: A trailer sliding suspension is remotely controlled to move between locked and unlocked positions. To unlock the sliding suspension, the driver initiates generation of a first signal which is communicated to an electronic control unit of a trailer anti-lock brake system. The electronic control unit then generates an unlocking signal in response to the first signal to unlock the sliding suspension such that a position of the sliding position can be adjusted relative to a trailer supported by the sliding suspension. Once the sliding suspension is in the desired position, the driver generates a second signal which is communicated to the electronic control unit. The electronic control unit then generates a locking signal in response to the second signal to lock the sliding suspension to a trailer body rail.

    摘要: A vehicle suspension assembly includes a height holding device that is at least partially supported within an air spring of the suspension assembly. The height holding device includes a hydraulic ram. A moveable portion of the hydraulic ram moves between a first position where a minimum clearance is maintained between suspension components and a second position where a larger clearance is maintained between the suspension components. The height holding device moves into the second position to maintain a desired height of the truck or trailer bed during loading and unloading operations at a loading dock, for example. The height holding device allows for the suspension air springs to be evacuated of air pressure during loading or unloading conditions without a change in deck height.
