FIELD: construction.
SUBSTANCE: support device (100) comprises a support (1) made capable to be inserted into contact with coupling rod (51), and holder (2) connected with support and attachable to the lower frame (60) of car body. Support is movable relative to the holder and along the holder at exceeding of critical force acting thereon in vertical direction. Support device additionally comprises a spring mechanism with spring element (3a, 3b, 3c), connected to support and holder by means of force transmission mechanism (10) for elastic element deformation by the support moving relative to the holder. Force transmission mechanism converts the force of elasticity arising as a result of deformation of spring element in supporting force opposite to the force acting on the support. Force transmission mechanism is designed for conversion of the distance made by support moving relative to the holder in deviation of the spring which deforms the spring element when support moves relative to holder. Force transmission mechanism is also made so that asynchronous correlation between characteristic curve of the supporting force and characteristic of the spring elastic element, to decrease support force in working zone of the support device the more the spring element is deformed.
EFFECT: preventing damage to the hinged device and/or the lower part of car body.
