A rubber bearing in accordance with claim 2, wherein a connection is provided for circulation of damping agent between said chamber or chambers formed in the vicinity of one axial end of the bearing and said chambers in said channel carrier. 4. A rubber bearing in accordance with claim 1, wherein an outer contour of said inner sleeve of said channel carrier and said second elastomer surrounding said inner sleeve have a cross section deviating from a circular shape, and an inner contour of said inner sleeve has an essentially circular cross-sectional shape. 5. A rubber bearing in accordance with claim 1, further comprising another elastomer; and an outer ring, said bearing inner part is formed from two carrier bodies, a first of said carrier bodies forming an entire middle area of said bearing inner part and a section of one axial bearing end which joins said middle area and has an increased diameter compared with said middle area, and a second of said carrier bodies is a ring forming another axial bearing end of increased diameter, said second of said carrier bodies being pushed over said middle area of said first of said carrier bodies, where in both said first of said carrier bodies and said second of said carrier bodies are surrounded in an area of the axial bearing ends by said another elastomer, said another elastomer having a part vulcanized to said first of said carrier bodies and to said outer ring, and having a part vulcanized to said second of said carrier bodies and to said outer ring. 6. A rubber bearing in accordance with claim 5, wherein said carrier body on said part forming said middle area of said bearing inner part has a shoulder provided at in the vicinity of a section of increased diameter for axial fixation of a position of said channel carrier. 7. A rubber bearing in accordance with claim 5, wherein said part of said carrier body forming said middle area of said bearing inner part has a flattened area on a circumferential surface for mounting the bearing in the correct position. 8. A rubber bearing in accordance with claim 5, wherein said carrier bodies forming said bearing inner part are designed as thin-walled hollow section elements. 9. A bearing comprising: a inner part with first and second ends and with a middle area, said first and second ends having a larger diameter than said middle area, said first and second ends and said middle area being rigid; an inner sleeve around said middle area of said inner part; a middle elastomer arranged around said inner sleeve and connected to said inner sleeve by vulcanization; a channel ring arranged around said middle elastomer and connected to said middle elastomer by vulcanization; a bearing shell arranged around said channel ring, said bearing shell and said channel ring defining a channel extending between said first and second ends of said inner part; a first end elastomer connected to said first end of said inner part and connected to a first end of said bearing shell; a second end elastomer connected to said second end of said inner part and connected to a second end of said bearing shell, said first, second and middle elastomers defining end chambers at said first and second ends of said inner part, said first, second and middle elastomers defining middle chambers at said middle area of said inner part, said channel connecting said end chambers, said middle chambers including first and second middle chambers arranged on diarmetrically opposite radial sides of said inner part. 10. A bearing in accordance with claim 9, wherein: said elastomers are mo
