Embodiment Construction

[0049] figure 1 A preferred embodiment of the hydropneumatic circuit 4 of the suspension system 1 according to the invention is shown. According to the invention, the control element S is connected to at least one of said components 2, 3 (not shown). Said parts 2, 3 are oscillatingly movable relative to each other and are mounted spring-loaded relative to each other. According to the invention, said control element S is connected in series with a hydropneumatic spring F1. The circuit 4 is filled with a hydraulic medium 13 having a flow direction 11 of a volume flow 17 shown. The hydraulic medium 13 in the control element S occupies a proportion of the volume V1. According to the variant shown, the control element S has two connections for the volume flow 17 of the hydraulic medium 13 . However, a known T-piece (T-piece) can be arranged on the control element S as a difference. The T-piece is usually a pipe or wire having the approximate shape of the letter "T". It is co...

Abstract

Suspension system for vehicle seats, in particular for utility motor vehicle seats, comprising at least a first and a second part, the two parts being mounted oscillatorily movable and spring-loaded with respect to one another, wherein a closed hydropneumatic circuit is provided which comprises at least one control element, connected to at least one of the two parts, and at least one first hydropneumatic spring connected in series therewith, a hydraulic pressure of a hydraulic medium in the circuit being convertible into a force acting between the two parts by means of an action surface arranged in the control element, the pressure being dependent on a gas pressure in a gas volume of the first spring.

Description

technical field [0001] The invention relates to the field of vehicles, more specifically, to a vehicle suspension system and a method for suspending and installing vehicle components. Background technique [0002] Agricultural and construction machines are often required to travel over very rough terrain. In these conditions, the driver will experience strong vibrations and collisions. These strong vibrations and impacts are applied to the driver through the vehicle body and seat. In order to dampen the vibrations loaded on the driver, the seats are usually equipped with passive suspension systems. Usually pneumatic springs and hydraulic shock absorbers and deflectors are used for this to connect the seat to the vehicle body, thereby reducing the transmission of vertical acceleration. However, these passive suspension systems quickly reach their physical limits, especially for low frequency oscillations. In this frequency range, the transmission of disruption is almost i...
