DEVICE TO INCREASE CROSS-COUNTRY CAPACITY OF AUTOMOBILE Russian patent published in 2008 - IPC B60B15/22 B60C27/04 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to additional equipment temporary mounted on wheels. Proposed device contains detachable grouser connected with lever made for fastening on automobile hub by support bolt passed through wheel disk, lever consists of three parts. Upper part forms, together with grouser, a common-l-shaped part in form of bent plate hinge-connected with middle part consisting of two shackles enclosing the plate, free ends of shackles being hinge-connected with third lower part of lever. The latter is essentially plate support of device of arbitrary form with holes in corners of isosceles triangle in plan, in vertex of which plate is arranged and hinge-fastened between said shackles. Said support bolt is fitted in one of two other holes. Bolt is provided with thread in middle part with turned-on locking washers with cylindrical projections pointed to each other, each being fitted in hole in support for free rotation. Lower part of support bolt is made cylindrical with flats for wrench on end not projecting beyond the contour of cylindrical part. Pin of cup is fitted in third hole of support. Axis of pin is displaced relative to axis of cup with eccentricity exceeding diameter of pin.

EFFECT: increased operating properties and reduced impact loads on parts of transmission.
