TORSION BEAM, TORSION BEAM UNIT AND TORSION TYPE SUSPENSION SYSTEM Russian patent published in 2017 - IPC B60G9/04 B60G21/05 

FIELD: automobile production.

SUBSTANCE: torsion type suspension system comprises a pair of arm elements, coil springs, shock absorbers and torsion beam. The torsion bar has a recess which extends in the longitudinal direction, the first and the second branches in a plane which is vertical in relation to the noted longitudinal direction and a substantially V-shaped or U-shaped cross section. The beam has connecting parts, a part of fixed shape, which is located in the central part and parts of an asymmetrical shape, which are arranged between this part of the fixed shape and the noted connection parts. In the part of fixed shape a recess has a constant depth, and the first and second branches have generally the same dimensions in thickness or width. In the parts of an asymmetrical shape a recess depth becomes gradually deeper from the connecting parts to parts of a fixed shape, and the first branch has a greater width than the width of the second branch.

EFFECT: possibility of constant rigidity maintaining while torsion beam twisting by changing the voltage profile which occurs in the torsion beam.
