1. A toothed belt comprising a belt body which extends substantially in a longitudinal direction (X) and which comprises a flexible material;
wherein at least one tension member is at least partially embedded in a flexible material of the belt body in the longitudinal direction (X), and wherein the at least one tension member is at least partially enclosed by the flexible material of the belt body;
wherein the belt body has a toothed side with teeth and tooth spaces which alternate in the longitudinal direction (X);
wherein a minimum thickness (a) of the flexible material of the belt body in a vertical direction (Z) on the at least one tension member of at least one of the tooth spaces corresponds at least to a minimum thickness (h) of the flexible material of the belt body in the vertical direction (Z) on the at least one tension member;
wherein the minimum thickness (h) is calculated as follows in dependence on thickness (d) of the tension member in the vertical direction (Z) and on material hardness (ShA) of the flexible material of the belt body in Shore A, where h=3*d/ShA.
