Abstract

The invention discloses a large-stroke independent suspension system of a super overload chassis. The large-stroke independent suspension system involves an upper cross arm, a lower cross arm, an oilgas spring and a height adjusting sensor, wherein the inner sides of the upper cross arm and the lower cross arm are hinged to a frame, wheel sets are connected between the outer sides of the upper cross arm and the lower cross arm through spherical hinges, the upper end and the lower end of the oil gas spring are hinged to the frame and the lower cross arm respectively, and the height adjusting sensor is mounted on the frame. The invention aims to provide the large-stroke independent suspension system of the super overload chassis, wherein the system can meet the requirements of the special vehicle super overload chassis on operation stability and driving smoothness.

Description

technical field [0001] The invention relates to the field of heavy-duty special vehicles, in particular to a large-stroke independent suspension system suitable for super-heavy-loaded chassis. Background technique [0002] The research on the double wishbone independent suspension system at home and abroad has been relatively rich, but there are few studies on the suspension system used in the super-heavy-duty chassis of special vehicles, especially for handling stability, ride comfort, and vehicle height adjustment. Fewer site studies are required. The existing double-wishbone independent suspension system cannot meet the requirements of the super-heavy-duty chassis of special vehicles for handling stability and ride comfort. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a large-stroke independent suspension system for a super-heavy-duty chassis, which can meet the requirements of the super-heavy-duty chassis...
