COMPANY HIGHLIGHTS ARGO-HYTOS Is Expanding Its Presence in France On Friday, July 10, 2015, in a fantastic summer weather, the new building of ARGO-HYTOS France in Forbach, in a beautiful situated location, was ofcially opened in the presence of customers, colleagues and family members. Didier Ledig, CEO of ARGO-HYTOS France, opened the festivities and presented the necessity of the decision to move from Sarreguemines to Forbach and erect an own building. Christian H. Kienzle, CEO of the ARGO-HYTOS Group, explained the history of ARGO-HYTOS France, which began in Paris in 1983 and now...

APPLICATION HIGHLIGHTS Comfort Hydraulics: Pitching Vibration Damping Coordinated solutions: Design to dedication Damping block for wheel and telescopic loaders Damping block with hydraulic accumulator The driving speeds of mobile machines in agriculture have steadily risen in recent years. This affects tractors with front loader as well as yard and wheel loaders and telescopic loaders. These mostly unsuspended vehicles tend to oscillate due to the mass distribution and the spring effect of the tires in both speed and direction changes as well as when driving over bumps. The kinematic of...

main control block system pressure tank control pressure min. 8 bar Schematic diagram Info Depending on the application, requirements and request, various functional elements can be combined almost arbitrarily. › Directional control valves for switching on and off 70 - 300 l/min › Pressures up to 350 bar › Block material of galvanized aluminum or steel › With or without accumulator protection and accumulator discharge › Accumulator without pre-charge › With constant or load-dependent pre-charge of the accumulator › With / without pipe rupture protection in the block › Piloting or bypassing...

APPLICATION HIGHLIGHTS Pitching Vibration Damping in a Wheel Loader Diaphragm accumul or Diaphragm accumulator p Hydr Hydraulic cont control block Machine control LiŌi LiŌing cylinder If a manufacturer turns to ARGO-HYTOS with the task of realizing a pitching vibration damping in a wheel loader, the customer accompanies the development process in close cooperation with our application experts up to a successful testing of the project. In a rst step, the current state is analyzed together with the customer. A matched to the wheel loader pitching vibration damping can only work efciently, if...

APPLICATION HIGHLIGHTS Comfort Hydraulics: MHPS - Hydro-Pneumatic Suspension Systems Modularity for faster and more cost-effective development Hydro-pneumatic suspension systems improve comfort and productivity of vehicles. The fact that these systems are currently utilized in only a small number of vehicles is mainly due to high development efforts and the additional costs of the suspension components. ARGO-HYTOS now offers a modular system, which features an improved cost-benet ratio and a reduced development effort. Moreover, two specially developed hydraulic solutions offer distinct...

The target of ARGO-HYTOS is therefore to remove these barriers for vehicle manufacturers and to advance the technology of hydro-pneumatic suspension systems. Development costs and development time shall be reduced considerably. This is accomplished with a new system solution, which is characterized by three particular benets: Fig. 3: Basic module with 4/3 position control valve 1. A standardized, modular control system for hydropneumatic suspension systems – including hydraulics and electronics 2. A straightforward adaptation of the system to customer-specic needs simply by choosing...

The basic module consists of a minimum of required hydraulic components. It is a manifold that provides position control of the suspension: it feeds or drains oil to/ from the suspension cylinder’s piston chamber. A special feature of it: it needs just one proportional valve with only one solenoid (see g.3), for upward and downward leveling. There are two advantages here as opposed to suspension manifolds commonly used at present; one solenoid can be eliminated, additionally the position adjustment can be done proportionally. This means that the valve can on react very sensitively to small...

The electronics needed to operate the manifold can be supplied as well should the customer request it. They consist of a position sensor and a position control unit in its most basic form. It is precongured according to the given hydraulic setup and can be adapted to an application by selecting algorithms and parameters. The electronics can be also equipped with operating elements, which enable the operator to manually adjust the normal position or the suspension characteristics (damping/spring rate). The control unit is able to receive further data from the vehicle’s CAN bus. At present,...

APPLICATION HIGHLIGHTS MHPS - Hydro-Pneumatic Suspension in a Self-Propelled Sprayer The best way to demonstrate the advantages of the modular concept is by using the example of the wheel suspension of a self-propelled sprayer with a production quantity of 15 - 20 machines per year: Due to the ever-growing demand on comfort and safety, chassis suspensions (the so-called wheel suspension) at self-propelled sprayers belong for quite some time to the delivery spectrum of the major manufacturers. In order to remain in business, a small manufacturer has to make large investigations in...

Schematic diagram The machine data such as weight of the machine, loading conditions, speed, etc. were the basis for the calculation of the new system. The design of cylinder sizes, pre-charging of the diaphragm accumulators or cable diameters was made by ARGO-HYTOS, based on these parameters. Based on the layout, the software has been congured and loaded into the control electronics, the control blocks and other accessories have been compiled. A rst functional test was carried out at ARGO-HYTOS, at the load test rig belonging to the company. Before the system has ever been installed, all...
