  • Devices using a dolly for reinforcing the loading capacity of tractor vehicles
    Patent number: 5067741
    Abstract: The invention relates to the control of the steering of the wheels of a dolly interposed between a tractor and a semi-trailer. The bars controlling the steering of the wheels of the dolly are actuated by a power system controlled from a pilot stage detecting the steering movement of the wheels of the tractor. The pilot stage comprises a pilot link freely rotating on a shaft and driven in rotation by a transmission connected to the steering lever of the wheels of the tractor; the rotation of the pilot link selectively controls a hydraulic valve which actuates a double-acting actuator connected to a link controlling the steering bars.
