DUAL AXLE AIR SUSPENSION VEHICLE Russian patent published in 2023 - IPC F16F9/00 

FIELD: vehicle suspensions.

SUBSTANCE: two-bridge air suspension of a vehicle contains a frame, support brackets, trailing arms, shock absorbers and air springs. Support brackets are installed on the frame with inner ends of trailing arms fixed to it by means of hinges. There are fastening points of the front and rear axles on the levers, hinges for fastening the lower bases of the front and rear shock absorbers, hinges of the lower supports of the front and rear air springs. The upper mounting units of the shock absorbers and the upper supports of the air springs are fixed to the frame. The lower supports of the air springs are fixed on the trailing arms between the attachment points of the bridges and the hinges of the support. Support diameter D is increased by L₂/L₁ times, where: L₁ is the distance between the axes of the hinges of the air spring supports and the hinges of the support, and L₂ is the distance between the outer ends of the trailing arms and the hinges of the support.

EFFECT: increased reliability of the balancer suspension of the vehicle while reducing the longitudinal overall dimension of the suspension.
