Embodiment Construction

[0076] exist figure 1 The exemplary embodiment of the hydraulic system according to the invention shown in can be used as a suspension system in a mobile work machine and in particular for position adjustment of an axle, wherein the left and right wheels of the axle can be adjusted individually. Hydraulic systems are suitable for the suspension of all types of vehicles, especially when no (more) hydraulic supply is provided in said vehicle or an air suspension is not suitable. The invention is not limited to figure 1 Position adjustments shown in . In particular, the depicted hydraulic system can be used as an axle suspension or as a single wheel suspension. Other suspensions are possible that require height adjustment, eg for adaptation to load conditions or for adjustment of ground clearance.

[0077] In particular, the hydraulic system comprises two position regulating circuits 29 and 30 which are configured accordingly. Position control loops 29 , 30 can be designed in...

Abstract

The invention relates to a hydraulic system, a hydraulic unit, a vehicle, a method and use. The hydraulic system for controlling or adjusting a hydraulic cylinder comprises at least one hydraulic cylinder; at least one hydraulic unit, by means of which the hydraulic cylinder can selectively be connected to a pressure source and a tank; and at least one controlling or adjusting device for controlling or adjusting the supply of hydraulic liquid to the hydraulic cylinder, the controlling or adjusting device forming a first assembly and the hydraulic unit forming a second assembly, and the first assembly and the second assembly are structurally separated from one another and are fluidically connected, wherein the supply of hydraulic liquid to the hydraulic cylinder is predominantly controlledor adjusted, from outside the hydraulic unit by means of the controlling or adjusting device, and the hydraulic unit is rigidly connected to the hydraulic cylinder.

Description

technical field [0001] The invention relates to a hydraulic system for controlling or regulating hydraulic cylinders. A hydraulic system of this type is known, for example, from EP 1 067 296 A1. The invention also relates to a hydraulic unit, a vehicle, a method and the use of a hydraulic unit. Background technique [0002] Known hydraulic systems are used in self-propelled forklifts which operate in an energy-efficient manner. For this purpose, the load-dependent pressure potential of the hydraulic fluid is used. Known hydraulic systems deal with the problem of the provision of a second supply pump for actuating consumers for auxiliary functions. For controlling the auxiliary functions, known hydraulic cylinders have complex control circuits, which lead to throttling losses. Contents of the invention [0003] The object of the present invention is to provide a hydraulic system for controlling or regulating hydraulic cylinders which has a simple, compact and reliable c...
