1. A chain link (2, 2,′ 2″) for a crawler chain (6), wherein the chain link (2, 2,′ 2″) comprises at least two roller tracks (29, 29′) extending in parallel, on whose running surfaces (21, 22; 21′,22′, 210, 220; 310, 320) at least one track roller (3) is movable during operation of the crawler, whereinthe at least two roller tracks (29, 29′) extend along opposite sides of a center line extending in a running direction of the tracks (29, 29′),the running surfaces (21, 22; 21′,22′, 210, 220; 310, 320) of the at least two roller tracks (29, 29′) are asymmetrical with respect to the center line, in both the running direction of the tracks (29, 29′) and transversely to the running direction of the tracks (29, 29′), have different running lengths and all have an identical height level, andare positioned with respect to one another such that gaps (40) transversely extending between adjacent running surfaces (21, 22; 21′,22′, 210, 220; 310, 320) are offset from one another in the running direction of the tracks (29, 29′) and do not continuously extend transversely across the tracks (29, 29′) and the center line of the tracks (29, 29′),such that the track roller (3) is always completely supported by one of the roller tracks (29) in parallel when passing over one of the gaps (40) and does not simultaneously pass over gaps (40) of both tracks (29, 29′). 2. The chain link according to claim 1, wherein the running surfaces of the at least two roller tracks at least cross-sectionally differ by different transverse dimensions along the running direction. 3. The chain link according to claim 1, wherein the running surface of at least one roller track extends from the outermost front end of the chain link in the running direction to the outermost rear end of the chain link. 4. The chain link according to claim 1, wherein at its front and rear ends of the chain link end as seen in the running direction, the chain link comprises one or more connecting means for the articulated, releasable connection with another chain link. 5. The chain link according to claim 1, wherein one or more running surfaces are rectangular or square-shaped, and the at least two running surfaces differ in the length of the running direction. 6. The chain link according to claim 1, wherein the running surfaces of the at least two roller tracks form a T-shape whose crossbars extend in running direction and whose longitudinal stems extend in a common direction transversely to the running direction, with adjacent T-shaped surfaces in the running direction oriented oppositely and complementary to one another, and adjacent T-shaped surfaces in the transverse direction oriented identically to one another. 7. The chain link according to claim 1, wherein in both the running and transverse directions, the adjacent running surfaces of the at least two roller tracks alternately form an H-shape and a cross shape. 8. The chain link according to claim 1, wherein the running surfaces are formed fork-shaped and are aligned to each other point-reflection, such that a stem of a fork engages into a fork opening of an adjacent chain link. 9. A chain for a crawler drive having at least two chain links according to claim 1. 10. The chain according to claim 9, wherein the chain links are identical and adjacent chain links are mounted in a manner rotated to each other by 180 degrees about an axis vertical to the running direction. 11. The chain link according to claim 1, wherein the track roller (3) has a guide wheel (33) separating two track rims (31, 32) having identical width and diameter, and with the diameter of the guide wheel (33) being greater than the diameters of the track rims (31, 32). 12. The chain link according to claim 1, wherein the running surfaces (21, 22; 21′,22′, 210, 220; 310, 320) of the at least two roller tracks (29, 29′) are all rectangular.
