Design improvement of a hydraulic stand for cold straightening of truck front axle beams

Abstract

The paper presents the design and operating principle of an improved hydraulic stand intended for cold straightening of truck front axle beams. Particular attention is paid to the arrangement of the load-bearing frame, supports, fixing and clamping devices, hydraulic cylinders, pump unit, distributor, high-pressure pipelines and measuring devices. The hydraulic drive provides smooth and controllable application of the straightening force without heating the beam. The main design parameters of the stand and the sequence of the restoration operation are substantiated.
