PNEUMO-HYDRAULIC TRACTION AND COUPLING DEVICE OF A FORESTRY CAR WITH TRAILER
The urgency of the need for constructive improvement of the towing device of a forest car with a trailer, aimed at increasing its reliability, reducing metal consumption, reducing fuel consumption of a forest car with a trailer due to the accumulation and reuse in the process of energy that is not efficiently dissipated into the environment of the energy generated in the traction coupling device when driving a road train. The conditions for the removal of forest materials by a timber truck with a trailer in the conditions of logging are described. The basic regulatory documents governing the requirements for the design of towing devices are considered. The main transient processes during the movement of a forest car with a trailer are described, which contribute to the appearance of large dynamic loads from the inertia of the forest car and trailer in the towing device. A promising design of a pneumatic-hydraulic towing device of a forest car with a trailer is proposed, which allows converting kinetic energy that inevitably arises in the towing device from the inertia forces of the masses of a forest car and trailer to potential for its further useful use in technological hydraulic equipment of a forest car with a trailer . The device and the operation of the pneumatic-hydraulic towing device of a forest car with a trailer are described. It is established that the use of the developed device will reduce fuel consumption, increase reliability and improve the smoothness of the forest car with a trailer.
