New technical device for traction tests of autotractor equipment

Abstract

Advanced agricultural production is based on innovative scientific developments. The priority direction is given to the technical support of the agro-industrial complex, which makes it possible to significantly increase labor productivity in this sector of the economy, including the quality of products. Autotractor equipment is not an exception in this regard. Correct operation, which largely depends on its timely and qualified maintenance, including tests. Traction tests of machines make it possible to establish and test their traction characteristics, economy, high-quality performance indicators of the main units, as well as control systems. Proposed is a new technical facility (load support) for traction tests of autotractor equipment, which includes a base, a support-brake plate installed on it for placement on it of tested equipment and traction-brake device. The design of the support and brake plate is made in the form of a treadmill. The base is made with the possibility of mounting a traction-braking device in it and is made in the form of a recess with a small ledge in the bottom part. Traction-braking device consists of two posts and support boards made in the form of parallelepiped. Front post is secured from base front wall element. The rear post is mounted on a small ledge on the side of the rear wall of the base. The structures of the lower part of the front pillar, as well as the upper part of the rear pillar, are firmly attached to the spar by braces. To the left and to the right of the installed posts there are locks in the form of bars. The advantages of the new technical device for traction tests of autotractor equipment are expressed in the improvement of operational properties through reduced weight and size characteristics, simpler design, as well as a small amount of preparatory work.
