| 20100107868 | Multi-part piston for an internal combustion engine and method for its production - The present invention relates to a multi-part piston ( | 05-06-2010 |
| 20100107999 | Multi-part piston for an internal combustion engine and method for its production - A multi-part piston for an internal combustion engine has an upper piston part with a piston crown, and a lower piston part with pin boss supports and pin bosses connected with the pin boss supports. The upper piston part and the lower piston part each have an inner and an outer support element, which elements delimit an outer circumferential cooling channel. The inner support elements delimit a cavity that is open toward the pin bosses. The cavity is provided with a separate cooling oil collector that has at least one cooling oil opening. | 05-06-2010 |
| 20100108000 | Multi-part piston for an internal combustion engine and method for its production - A multi-part piston for an internal combustion engine has an upper piston part having a piston crown, and a lower piston part. The lower piston part has pin boss supports and pin bosses connected with them and the upper piston part and the lower piston part each have an inner and an outer support element, which elements delimit an outer circumferential cooling channel. The inner support elements delimit a cavity that is open toward the pin bosses. The cavity has a separate cooling oil collector that has at least one cooling oil opening. The piston is produced by manufacturing the upper piston part and lower piston part, inserting the cooling oil collector into the upper piston part or lower piston part, and joining the upper and lower piston parts together by friction welding. | 05-06-2010 |
| 20100108001 | Multi-part piston for an internal combustion engine and method for its production - A multi-part piston for an internal combustion engine has an upper piston part having a piston crown, and a lower piston part having pin boss supports and pin bosses connected with them. The upper piston part and lower piston part each have an inner and an outer support element, which delimit an outer circumferential cooling channel. The inner support elements delimit a cavity that is open toward the pin bosses, and the cavity is provided with a separate cooling oil collector that has at least one cooling oil opening. In a method for producing a piston, the upper and lower piston parts are manufactured, the cooling oil collector is inserted into one of the upper and lower piston parts in a region of the cavity, and the upper and lower piston parts are connected together at their support elements. | 05-06-2010 |
| 20100108016 | Multi-part piston for an internal combustion engine and method for its production - The present invention relates to a multi-part piston ( | 05-06-2010 |
| 20110232480 | Piston for an internal combustion engine - A piston for an internal combustion engine has at least two hub bores for holding a piston pin. The hub bores are formed with a cylindrical inner contour and are provided with a coating comprising a resin with solid lubricant particles embedded therein. The coating forms at least one geometric deviation from the cylindrical inner contour of the hub bores. A method for producing a piston of the type, includes producing bores with a cylindrical inner contour and applying a coating medium comprising a resin with solid lubricant particles embedded therein to the inner faces of the bores by a coating tool, such that the resulting coating forms at least one geometric deviation from the cylindrical inner contour of the hub bores. | 09-29-2011 |
