SUSPENSION FOR VEHICLE Russian patent published in 1995 - IPC

FIELD: automotive industry. SUBSTANCE: suspension has shock-absorber 3 and double-arm balance beam 6. The top short arm of the balance beam is pivotally connected with guide rod 9. Additional compression spring 10 is mounted on the rod. The spring is mounted freely and is not in operation when a vehicle is unloaded. Additional compression spring 10 is interposed between flange 11 of rod 9 and supporting plank 12 secured to the frame. Guide rod passes through the opening in the plank. To exclude deformation of additional spring 10 due to its bending in operation, movable support 13 provided with the opening for guide rod 9 is mounted on the same axle as supporting plank 12 is. Movable support 13 is made up as a segment of a cylinder. The cylindric surface of the support is mated with the cylindric hollow in the supporting plank to define a kinematical pair. EFFECT: improved shock absorbing. 2 cl, 6 dwg
