Definitions
- the invention relates to a drive unit, in particular a motor-pump unit for slip-controlled brake systems, according to the preamble of claim 1.
- Drive units with a device for converting rotary and translatory, for example oscillating, motion sequences find a wide range of applications in general mechanical engineering.
- the use of such drive units is of particular importance in industrial hydraulics, vehicle hydraulics and process engineering, even if the operating conditions are quite different, the kinematics of the units can be permanently controlled with high precision.
- a pump unit actuated by an electric drive unit supplies pressure medium to a slip-controlled motor vehicle brake system.
- the drive shaft of the electric motor has an eccentric pin at the shaft end, on which two pump pistons of a radial piston pump are supported by a needle bearing.
- the pin which is attached to the stub shaft off-center then describes an eccentric track curve which leads to the oscillating movement of the pump pistons. Due to the piston stroke determined by the eccentric cam curve, the current design permits a variation in the delivery volume only to a limited extent, for example via a speed control of the electric motor, which can be regarded as worthy of improvement due to the considerable control measures.
- FIG. 2 shows a partial view of the radial piston pump according to FIG. 1 at the interface A-A
- FIG. 3 shows a top view of the adjusting element arranged between the second eccentric and the control slide.
- FIG. 1 shows a drive shaft 3 assigned to an electric motor, the shaft end of which is provided with a peg-shaped first eccentric 1.
- the end of the first eccentric 1 facing away from the drive shaft 3 protrudes eccentrically into the control slide 5 shaped as a hollow pin.
- a feather key or insert 8 inserted in a longitudinal groove 7 of the first eccentric 1 establishes the positive connection to the bore 9 arranged eccentrically in the hollow cylinder, into which a longitudinal groove 7 is inserted, so that the control slide 5 rotates with the first eccentric 1.
- the control slide 5 assumes the function of a slide bearing guiding the eccentric pin.
- a roller bearing for guiding the drive shaft 3 is arranged on the shaft section opposite the control slide 5.
- the actuating element 4 is fastened to the mutually facing end faces of the control slide 5 and the second eccentric 2.
- the second eccentric 2 rolls in an adjustable manner relative to the first eccentric 1 on a needle bearing 10, so that the pump pistons 11 arranged on the outer bearing ring perform an oscillating stroke movement.
- a control piston 6 oriented perpendicular to the end face of the control slide 5 is under pump or consumer pressure on the end facing away from the control slide 5.
- the basic The control slide 5 is caused by the actuating element 4 held between the control slide 5 and the second eccentric, the compression spring 12 resting against the stop 13 positioning the control piston 6 on a stop surface fixed to the housing and facing away from the compression spring 12.
- FIG. 2 shows with reference to FIG. 1 at the interface A-A the cross section through the drive shaft 3 accommodating the first eccentric 1, and the needle bearing 10 fastened on the second eccentric 2, on which the pump pistons 11 lie diametrically.
- the first eccentric 1 has a rotation by the eccentric dimension El
- the second eccentric 2 has a rotation by the eccentric dimension E2 with respect to the drive shaft 3, so that the radial distances E1, E2 are dependent on the same angle of rotation and thus equal
- the line of action determines the variable total dimension forming the total stroke of the pump pistons 11.
- FIG. 3 shows the top view of the corrugated, essentially sickle-shaped adjusting element 4, which extends in the circumferential dimension over approximately 270 degrees.
- the control element 4 has a plurality of holding bores 14.
- the section between 180 and 270 degrees acts as a torsion spring, the holding hole 14 is attached to the end face of the second eccentric 2 at the second end of the resilient section (270 ° position).
- the control piston 6 displaces the control slide 5 which rotates with the first eccentric 1, as shown in the drawing, to the left, so that the distance dimension is reduced proportionally x the axial distance between the second eccentric 2 and the control slide 5 is also reduced.
- the actuating element 4, which is under pressure, as a spring element performs a twist, as a result of which the translational movement of the control slide 5 leads to a rotational movement of the actuating element 4 and thus also the second eccentric 2 comes into effect.
