Definitions
- the invention relates to a hydropneumatic suspension system for motor vehicles according to the kind defined in the preamble of claim 1.
- Hydropneumatic suspension systems offer decisive advantages in terms of robustness, suspension comfort and quick and easy controllability. However, the characteristics depend to a large extent on the loading condition.
- a conventional hydropneumatic suspension system consists of the basic elements of gas pressure accumulator, hydraulic cylinders and the connecting old pressure lines. Instead of the normal leaf, air or coil springs, hydraulic cylinders are installed between the axle and frame. These are connected to gas pressure accumulators via lines. The gas in each pressure accumulator serves as a spring, the oil column in the line system serves as a transmission medium for the gas spring forces to the hydraulic cylinders. The damping takes place in the area of the oil column by appropriate devices in the direction of deflection and rebound.
- DE 40 03 493 AI describes a hydropneumatic suspension system with the hydropneumatic support assemblies assigned to the vehicle wheels and a level control interacting therewith, which, depending on the stroke position of the wheels, introduces hydraulic medium from a reservoir into the support assemblies or hydraulic medium from the support assemblies into the reservoir.
- an active bypass and delivery system is arranged between the support members, which, depending on the lift position and / or pitching or rolling moments acting on the vehicle, bypasses the reservoir with respect to the longitudinal axis of the vehicle and / or bypasses the reservoir. or the support units located opposite the transverse axis of the vehicle.
- the hydraulic medium between the support units is different
- the present invention is based on the object of presenting a hydropneumatic suspension system which can represent the functions of suspension, roll stabilization and level control without an additional control unit and actuators with a reduced number of parts.
- the object on which the invention is based is achieved by a generic hydropneumatic suspension system which also has the characterizing features of the main claim.
- Another advantage is that by lowering the inside of the vehicle for roll stabilization, the lateral acceleration is reduced, the center of gravity of the vehicle is lowered and the road holding of the vehicle is thus improved.
- the solution according to the invention can be implemented in at least four constructive variants.
- the pressure supplies are separated from the suspension and level control, while in a second exemplary embodiment they are supplied by a central pump.
- the third and fourth embodiments show a separate system for the front and rear axles, in which the axles can be controlled independently of one another.
- FIG. 1 shows a first exemplary embodiment of a hydropneumatic suspension system for a two-axle motor vehicle with separate pressure supply for suspension and level control;
- FIG. 2 shows a second exemplary embodiment of a hydropneumatic suspension system, in which the suspension and the level control are supplied by a central pump;
- FIG. 3 shows a further exemplary embodiment of a hydropneumatic suspension system in which the front axle can be regulated independently of the master axle and
- the front axle 1 like the rear axle 2, has a hydropneumatic suspension system consisting of two piston-cylinder units, each with two chambers, hereinafter referred to as spring cylinders.
- the spring cylinders 3 and 4 of the front axle 1 and the spring cylinders 5 and 6 of the rear axle 2 are identical in construction and dimensioned according to the respective axle load.
- the function of the spring cylinders 3, 4, 5, 6 will be explained with reference to the spring cylinder 6 of the rear axle 2.
- the piston rod 7 is connected to the rear axle 2 via a joint 8.
- the control pressure of the roll stabilization system acts in the lower spring cylinder chamber 9.
- the pressure of the suspension and level control system acts in the upper spring cylinder chamber 11 above the piston 10.
- the upper spring cylinder chamber 11 is connected to the corresponding upper spring cylinder chamber 12 of the opposite spring cylinder 5 of the rear axle 2 via a pipe 13.
- a switching valve 14 is arranged in the pipeline 13 and is open when roll stabilization is active.
- the switching valve 14 is controlled without current for safety reasons and the closed position is thus reached.
- the control valve 15 is also de-energized and brought to a neutral open position via an integrated, mechanical centering.
- the upper spring cylinder chambers 11 and 12 are separated from one another and thus act as a stabilizer.
- a damping valve 17 is arranged, which regulates the damping of the spring process by the two throttle devices 18 and 19 acting in different directions in each case in an adapted intensity.
- the level is regulated by changing the oil volume in the suspension hydraulics.
- a pump 20 which via a flow valve 21 and a control valve 22 01 in the suspension system, ie in the upper spring cylinder rooms 11, 12, 23, 24, pumped via the switching valves 25 and 26.
- the damping valves 17, 27, 28, 29 are designed to be controllable.
- the damping characteristics of the spring cylinders 3, 4, 5 and 6 can also be varied as a function of the axle load, for example by influencing the electromagnetic force of the throttle devices 18, 19, 30 and 31 and 32, 33, 34 and 35.
- a valve 36 which supplies the roll stabilization in the open position and controls the level control in the closed position by activating the switching valves 25 and 26.
- the flow dividing valve 21, the control valve 22 and the pump 20, which are shown in the hydropneumatic suspension system according to FIG. 1, are not required in this arrangement.
- the high-performance pump 37 offers the additional advantage that the level control can be carried out in a very short time when the vehicle is at a standstill. When using a Central pump 37 for all functions, this must be dimensioned somewhat larger, but you can therefore do without a pump and an oil container.
- each axle can be regulated independently and, despite the same size of the spring cylinder, different pressure ratios in accordance with the front and rear Set the axle loads or the load status.
- the vehicle can be tilted on both sides around the longitudinal axis of the vehicle to make it easier to get in especially interesting for city buses
- FIG. 4 shows a simplified variant of the hydropneumatic suspension system shown in FIG. 3, in which only one-sided kneeling can be represented by using the switching valves 14, 25, 26 and 42.
