Definitions
- the invention relates to a multi-part cooled piston for an internal combustion engine according to the preamble of claim.
- European Patent Application 0 604 223 A1 discloses a piston which is used in a diesel engine and which consists of a piston upper part and a piston lower part.
- the upper piston part is screwed onto the lower part of the piston via a threaded bolt mounted centrally on the upper part of the piston and via a threaded hole incorporated in the lower part of the piston.
- a threaded bolt mounted centrally on the upper part of the piston and via a threaded hole incorporated in the lower part of the piston.
- a lock nut In order to achieve a permanent assembly connection, it is necessary to secure the screw connection by means of a lock nut.
- the disadvantage here is that during assembly of the piston, only a short piece of the threaded bolt between the pin bosses appears, so that it is difficult to screw on a lock nut.
- a piston according to the preamble of claim 1 is described in EP 04 696 66 A1.
- the invention is based on the problem of designing the upper and the lower part of a multi-part, cooled piston such that a simple assembly of the piston upper part on the piston lower part is possible without the additional use of a lock nut or other securing means.
- a multi-part cooled piston 1 which consists of a piston upper part 2, which has a combustion bowl 3 and an annular wall 4 with a ring portion 5, and a piston lower part 6, which has a box-shaped piston shaft 7 and two associated pin bosses 8 each comprises a pin bore 9 for receiving a piston pin, not shown in the figure.
- the upper piston part 2 and the lower piston part 6 delimit an outer annular cooling channel 10 and an inner cooling channel 11 arranged concentrically therewith, wherein the outer cooling channel 10 has at least one inflow opening 12 for introducing cooling oil and is connected to the inner cooling channel 11 via at least one overflow channel 13 ,
- This overflow channel 13 may be formed as a bore.
- two opposing overflow channels 13 may be provided here.
- the inner cooling channel 11 has at least one drain hole 14, via which the cooling oil can escape from the inner cooling channel 11.
- the upper piston part 2 is in this case on the one hand via an annular bearing surface 15 which is arranged on the combustion bowl 3 side facing away from the piston upper part 2, on an upper support surface 16 of an annular support rib 17 of the piston lower part 6 and on the other via a on the underside of the annular wall 4 located cross-sectional area 18 mounted on an upper cross-sectional area 19 of an annular support web 20 of the piston lower part 6.
- the bearing surfaces 15 and 16 form an inner, planar and horizontally arranged, or roof or plate-shaped support 21 and the cross-sectional surfaces 18 and 19 a to the inner pad 21 coaxially and horizontally arranged, or also roof or plate-shaped, outer pad 22nd
- the support web 20 is formed step-shaped, so that the piston upper part 2 can be centered by a machined into the inside of the lower part of the annular wall 4, cylindrical recess 23 in that during assembly of Kolbenober- and -unterteil the inner wall of the cylindrical recess 23 with the cylindrical Front side 24 of the support web 20 comes into contact, wherein it is necessary that the inner diameter of the cylindrical recess 23 is greater by such a tolerance measure than the outer diameter of the cylindrical end face 24 of the support web 20 that a trouble-free mounting of the upper part 2 is ensured on the lower part 6 ,
- On the combustion bowl 3 side facing away from the piston upper part 2 has a centrally and coaxially to the longitudinal axis 25 of the piston 1 arranged bolt 26, whose end 27 is provided with a thread 28.
- the region 31 between the annular support rib 17 of the piston lower part 6, which defines the inner cooling channel 11 together with the piston upper part 2, is formed relatively thin-walled and is provided in its center with a coaxial with the longitudinal axis 25 of the piston 1 arranged bore 29, the one on the thread 28 of the bolt 26 has matching internal thread 30.
- the piston upper part 2 may consist of an oxidation-resistant and / or heat-resistant material.
- the piston lower part 6 consists of a precipitation-hardening ferritic-pearlitic steel or tempered steel, the steel grades 38MnVS6 or 42CrMo4 typically being used (according to the German Steel-Iron-Material-Sheet 101).
