VEHICLE SUSPENSION Russian patent published in 2004 - IPC

FIELD: automotive industry; passenger cars.

SUBSTANCE: proposed suspension of car is made in form of support beam one end of which is connected to frame by bracket and other end is connected to wheel hub. Support beam is arranged lengthwise the car being made of two coaxially arranged sleeves. Outer sleeve is secured by its closed side on axle of bracket, and inner rod sleeve provided with movable brace adjustable length in axial space is coupled with bracket by pair of levers resting on profiled corner cams of bracket through thrust rollers. Bridges between walls of sleeve form four chambers creating hydrogas unit for synchronization of bringing together and release of wheel axles. Two chambers from side of sleeve end faces are filled with gas and are interconnected through calibrated channel. Inner chambers interconnected by channel are filled with hydraulic fluid of pressure lower than pressure in gas chambers. Piston is located between inner chambers. Working area of piston from side of bracket is greater than working area from side of wheel. Spring are fitted in two chambers from side of wheels. Outer sleeve is mechanically connected with spring-stabilizer.

EFFECT: provision of lead in suspension system of pair of forces influencing bringing to and release of vehicle wheel axle at straight-ahead running wheel at least one wheel-meets road obstacle or pit on road.
