Definitions
- the invention relates to a device for suspension and roll stabilization of motor vehicles according to the kind defined in the preamble of claim 1.
- Active chassis systems which work in conjunction with a hydropneumatic suspension and which shift hydraulic medium from the hydropneumatic suspension struts on one side of the vehicle to the hydropneumatic suspension struts on the other side of the vehicle by means of one or more displacement units, so as to influence the roll angle of the body structure, are known from the prior art .
- a hydropneumatic suspension either replaces a conventional suspension of the body structure or its stabilizers.
- a system in which a hydropneumatic suspension replaces a conventional suspension of the body structure is known from DE 39 36 987 C2.
- This system is characterized by an active counteraction against rolling and pitching movements of the vehicle by actively moving hydraulic medium directly between the support members of different vehicle sides or between the front and rear support units in order to raise or lower one side of the vehicle while lowering the other side of the vehicle to move the front part of the vehicle in a corresponding manner in the opposite direction to the rear of the vehicle.
- this has the disadvantage that additional stabilizers are required in order to ensure the required passive roll rigidity of the vehicle and thus safe driving.
- a device for stabilizing the vehicle superstructure against cornering in which the hydropneumatic suspension replaces the stabilizers and a pressure medium depending on the cornering directly to the pistons of cylinder-pistons interposed between the wheels and the vehicle superstructure Units, in particular hydropneumatic springs, are conveyed in such a way that the cylinder-piston unit assigned to the inside wheel is shortened in the sense of lowering the vehicle superstructure and the cylinder-piston unit assigned to the outside wheel is lengthened in the sense of lifting the vehicle body .
- a disadvantage of the prior art, as described in DE-OS 20 48 323, is the fact that additional body springs are required which have a negative influence on the overall stiffness of the vehicle. In both devices known from the prior art it also has a negative effect that, in addition to the active hydropneumatics, there are further passive suspension elements in the vehicle which provide passive roll rigidity against which an active device has to work, which has an unfavorable effect from an energy point of view .
- the present invention has for its object to present an active device for suspension and roll stabilization of motor vehicles, in which additional springs and stabilizers can be dispensed with.
- the object on which the invention is based is achieved by a generic device for suspension and roll stabilization of motor vehicles, which also has the characterizing features of the main claim.
- a generic device for suspension and roll stabilization of motor vehicles which also has the characterizing features of the main claim.
- the hydropneumatic device for suspension and roll stabilization of motor vehicles can simultaneously provide the full required lifting and rolling rigidity.
- the hydropneumatic device for suspension and roll stabilization of motor vehicles thus takes over the complete suspension of the motor vehicle, so that additional springs or stabilizers can be dispensed with, which offers advantages in terms of cost, weight and installation space in addition to the energy benefits.
- Fig. 1 shows various embodiments of an inventive and 2 inventive device for suspension and roll stabilization of motor vehicles.
- FIG. 1 shows, as a first advantageous embodiment of the invention, an active hydropneumatic suspension with a rigid axle 1 and vehicle wheels 2 and 3 attached to it.
- a rigid axle 1 is connected to a body structure 4 by means of axle-side joints 5, 6 and body-side joints 7, 8 via two spring cylinders 9 and 10.
- the spring cylinder 9 is articulated on the rigid axle 1 with a piston rod 11 in the joint 5.
- a piston rod 12 of the spring cylinder 10 engages in the joint 6 of the rigid axle 1.
- Each of the spring cylinders 9 and 10 has an upper spring cylinder chamber 13 and 15 and a lower spring cylinder chamber 14 and 16.
- the spring cylinder spaces 13 and 14 are separated from each other by a separating piston 17, the spring cylinder spaces 15 and 16 by a separating piston 18.
- a line 19 connects the upper spring cylinder space 13 of the spring cylinder 9 to the lower spring cylinder space 16 of the spring cylinder 10.
- a line 20 connects the upper spring cylinder space 15 of the spring cylinder 10 to the lower spring cylinder space 14 of the spring cylinder 9.
- a memory 23 and 24 is connected to each of the lines 19 and 20 via lines 21 and 22. Damping elements 25 and 26 are attached in the lines 21 and 22, which additionally weaken roll movements.
- An actuator 27 is connected to lines 19 and 20 via lines 28 and 29. This actuator 27 is an actuating or shifting device that makes it possible to generate active rolling moments. The actuator moves the medium from one side of the vehicle to the other, which means that the roll stabilization is achieved.
- tion elements 30 and 31 and memory 32 and 33 integrated in the cross-connected lines 19 and 20.
- the overall rigidity of the device for the suspension and roll stabilization of motor vehicles is composed of the stroke and roll rigidity of the rigid axle 1.
- n is the polytropic exponent
- AK is a piston surface 34
- AR is a piston ring surface 35
- 37 is the pressure in a reservoir 23
- V is the gas volume of the reservoir 23
- 24 is the track width of axis 1.
- the required roll and stroke rigidity of the entire device for suspension and roll stabilization of motor vehicles can be achieved in that the dimensioning of piston surfaces 34, 36 and piston ring surfaces 35, 37 in a ratio
