FIELD: engines and pumps. ^ SUBSTANCE: proposed suspension comprises steel ropes, thrust sleeves, lower crossarm with ribs arranged on both sides to receive adjusting bolts with moving crossarm mounted there between. Said moving crossarm has prismatic slot accommodating prismatic plate moving support with cylindrical recess receiving damper outer case lower end interacting, via flexible element with cone that accommodates adjusting sleeve interacting with polished rod. The latter is arranged in chamber formed by cylindrical bores of adjusting sleeve, cone and moving support. Proposed suspension incorporates damping assembly made up of cone cylinder accommodating damping element interacting with tapered thrust sleeve coupled with adjusting sleeve and thrust sleeve. ^ EFFECT: higher reliability. ^ 3 dwg, 2 cl |
