Problems solved by technology

[0002] Due to the particularity of non-highway vehicle systems such as chariots, the shock absorption system is generally poor. In harsh working environments such as combat, and limited by road conditions, weather and other conditions, the occupants are often subject to strong bumps, which can cause serious damage to the human body. damage

Abstract

The invention relates to a nonlinear seat suspension. The nonlinear seat suspension comprises a lower frame, an upper frame, a first connecting rod and a second connecting rod which are arranged between the lower frame and the upper frame, an adjusting rod arranged in the upper frame, a hand wheel arranged at one end of the upper frame for driving the adjusting rod to rotate, main springs arranged at the two sides of the adjusting rod, a first sliding block and a second sliding block arranged at one end of the main springs, a first boss arranged on the second sliding block, a torsion bar arranged on the upper frame, a second boss arranged on the torsion bar, and a third connecting rod of which the two ends are hinged to the first sliding block and the first connecting rod respectively. The middle of the first connecting rod is hinged to the middle of the second connecting rod. Negative rigidity is achieved through the torsion bar, and force acting on the upper frame and displacement of the upper frame are nonlinear through cooperation of the torsion bar and the main spring; the structure is simple, low-frequency vibration caused by the working environment can be effectively isolated, and therefore the body health of the driver is guaranteed.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a nonlinear seat suspension. Background technique [0002] Due to the particularity of non-highway vehicle systems such as chariots, the shock absorption system is generally poor. In harsh working environments such as combat, and limited by road conditions, weather and other conditions, the occupants are often subject to strong bumps, which can cause serious damage to the human body. damage. [0003] The present invention designs a seat nonlinear suspension, which is composed of upper and lower frames, adjustment rods, sliders, springs, torsion bars and other structures. After adjusting the weight and height, the non-linear suspension can well absorb the shock of the chassis and ensure the comfort of the passengers. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a non-linear seat suspension for the defects in the ...
