摘要： A gooseneck trailer coupler is disclosed which secures a first structure such as a towing vehicle to a second structure such as a trailer. The coupler is provided with a mounting element extending from the first structure, a chuck having a top end and a base at a bottom end opposite the top end, with the chuck attached to the mounting element at the top end and adapted to receive a ball mounted to the second structure. A locking assembly is adapted to releasably secure the ball and the chuck, and comprises a ring gear mounted around the chuck and movable from a locking position where the chuck is secured with the ball and an unlocking position where the chuck is unlocked from the ball, wherein the ring gear translates from the base toward the top end of the chuck as the ring gear moves from the locking position to the unlocking position. The locking assembly can also comprise at least one jaw mounted in the chuck for engaging the ball when the ring gear is in the locked position. A novel release lever assembly is also disclosed which moves the ring gear.

摘要： A trailer brake system includes a control sensor adapted to provide a signal when the braking system of the tow vehicle is actuated, at least one trailer brake actuated by pressurized brake fluid, a brake fluid reservoir, a brake fluid pump receiving fluid from the brake fluid reservoir, and a first solenoid valve connected to the brake fluid pump and directly connected to the trailer brake. A brake fluid accumulator receives pressurized brake fluid from the brake fluid pump and is connected to the first solenoid valve to quickly provide pressurized brake fluid to the trailer brake to increase the braking force. A second solenoid valve connects the trailer brake and the brake fluid reservoir so that brake fluid can be returned to the reservoir to reduce to reduce the fluid pressure and resulting braking force. A feedback pressure sensor is capable of generating a signal that represents braking force applied to the trailer brake. A controller is in communication with the control sensor, the first solenoid valve, the second solenoid valve, and the feed back sensor and is adapted to selectively open the first valve to increase braking force applied to the trailer brake and to open the second solenoid valve to decrease braking force to the trailer brake. The controller automatically provides a predetermined braking force to the trailer brake by selectively opening and closing the first and second valves as required to maintain the predetermined pressure. When the control sensor indicates the degree to which the braking system of the tow vehicle is actuated, the controller is can automatically provide different braking forces depending on the degree to which the braking system of the tow vehicle is actuated.

摘要： A trailer jack system includes an electric linear actuator having an electric motor, a source of electric power, and a controller that supplies a first voltage to the electric motor when the electric linear actuator is loaded and a second voltage to the electric motor when the electric linear actuator is unloaded. The electric linear actuator also includes a cylindrically shaped housing, a leg coaxially extending and retracting from the housing, and a support foot at a free end of the leg. The controller supplies the first voltage to the electric motor when a motor current of the electric motor is below a predetermined threshold value and supplies the second voltage to the electric motor when the motor current is above the predetermined threshold value. Preferably, the first voltage is about 24 volts and the second voltage is about 12 volts.
