Definitions

• the invention relates to a multi-plate clutch or multi-disc brake with a spacer according to the preamble of the first claim.
• a multi-plate clutch or multi-plate brake is known to consist of inner and outer plates and the associated plate carrier.
• the lamella / lamella support is made using a positive connection, for example a dovetail profile.
• Both the inner and the outer disk carrier have longitudinal grooves running in the axial direction. The slats can be moved axially through these longitudinal grooves.
• a closing of the multi-plate clutch or multi-plate brake occurs because, for example, a piston presses the multi-plates against an end stop.
• the clutch or brake is opened by pushing the piston back into its rest position, for example by means of a spring. When open, a coolant and lubricant flows through the plate pack.
• the clutch or brake is opened, the actual play of the disks is not uniform. For example, individual fins can be in contact with one another and the lubricant and coolant causes individual fins to stick together.
• a friction clutch is known from DE-OS 20 30 408. Every second outer plate carries a rubber-like spacer. The spacer is installed by pressing or pulling it through a hole in the driving profile of the outer lamellae. This arrangement has the disadvantage that each spacer must be inserted individually. Damage to the spacer cannot be ruled out due to the type of installation. Another disadvantage is that the type of assembly results in uneven volumes on the left or right side of the outer lamella. This results in uneven spacing of the outer lamellae.
• the object of the invention is to ensure a safe separation of the slats and to strive for an assembly-friendly solution.
• the object is achieved in that the spacer is in one piece and elastic.
• the solution according to the invention offers the advantage that the spacer is clipped onto the outer circumference of all outer lamellae in only one work step or the spacer is clipped onto the inner diameter of all inner lamellae in one step.
• assembly time is significantly reduced and assembly work is reduced.
• the advantage of the one-piece construction is that the spacing of the lamellae specified by the spacer is exactly maintained.
• the spacer be arranged between the outer plates or between the inner plates.
• a spacer be arranged between the inner plates and a spacer between the outer plates.
• the spacer consist of a rod-shaped base body with disk-shaped elements.
• the disc-shaped elements have constrictions on the outer circumference in the radial direction. This has the advantage that the type and configuration of the disc-shaped
• a disc-shaped element is to be understood to mean both elements with a circular and elliptical cross section.
• the spacer consist of a rod-shaped base body with spherical elements. In this way, a different force-displacement curve of the closing clutch can be achieved. In a further embodiment it is proposed that the spacer consist of an elastomeric material.
• Another solution according to the invention consists in that a spacer is applied on both sides of the entrainment profile, for example by vulcanizing or gluing.
• the spacer is applied to every second outer plate and / or inner plate.
• Fig. 5 spacers with spherical elements.
• FIG. 1 shows a segment of an outer lamella 1 with two driving elements 2A and 2B.
• the counterpart of the driving elements 2A and 2B is an axial groove of an outer disk carrier (not shown).
• the transmission of the rotary movement of the slat / slat carrier is thus carried out in a form-fitting manner by the connection of the driving element / groove.
• the driving element 2B has a recess.
• the spacer 3 is clipped into this recess during assembly.
• the spacer 3 is clipped onto all outer slats in only one work step.
• FIG. 2 shows a section along the line II-II from FIG. 1.
• Four outer plates 4 and three inner plates 5 are shown.
• the spacer 3 is clipped into the outer plates.
• a spacer with a rod-shaped base body 6 and three disk-shaped elements is shown Elements 7.
• the disc-shaped elements 7 ensure the equidistance of the outer slats.
• the disk-shaped elements 7 can be designed as a cylindrical body or an elliptical body.
• FIG. 4 shows the rod-shaped base body 6 from FIG. 3 and four disk-shaped elements 8.
• the disk-shaped elements 8 have constrictions on the outer circumference in the radial direction. These constrictions allow the force-displacement curve of the closing clutch to be specified.
• FIG. 5 shows a further embodiment of the spacer. This consists of a rod-shaped basic profile 6 and four spherical elements 9.
