1. A transport roller, comprising:a wheel (18), which is carried in a rotary manner on a fixture (10); a one- or multi-piece bearing block (20), which is fixed to the fixture (10) or is a component of the fixture; two sections (201, 20r) of the bearing block (20) run outside the wheel (18) in its peripheral area on opposite sides of the wheel (18); each section (20l, 20r) has a pivot bearing (22), on which a brake lever (24l, 24r) is carried; and the brake levers (24l, 24r) are connected by a spring (30) at their end (24lo, 24ro) running above the pivot bearing (22) in such a way that a spacing of the brake levers (24l, 24r) at their ends (24lo, 24ro; 24lu, 24ru) is variable by means of a change in the spring length between the linking points of the spring (30) to the brake levers (24l, 24r). 2. The transport roller according to claim 1, wherein the bearing block (20) whereof runs essentially parallel to the wheel axis and overlaps the wheel (18) with a gap.3. The transport roller according to claim 1, wherein first arms (24lo, 24ro) of the brake levers (24l, 24r) running above the pivot bearing (22) are shorter than second arms (24ru, 24lu) of the brake levers (24l, 24r) running below the pivot bearing (22).4. The transport roller according to claim 1, the brake levers (24l, 24r) whereof are coupled on the bearing block (20) in a structurally identical, but mirror-inverted manner.5. The transport roller according to claim 1, the brake levers (24l, 24r) whereof are bent in the direction of one another at their end (24lu, 24ru) running below the pivot bearing (22).6. The transport roller according to claim 1, with which the ends (24lu, 24ru) of the brake levers (24l, 24r) running below the pivot bearings are designed with brake linings (26).7. The transport roller according to claim 1, the pivot bearings (22) whereof consist of bolts, whose axes run parallel to the wheel plane.8. The transport roller according to claim 1, with which the spring (30) is designed as a leaf spring.9. The transport roller according to claim 1, with which the spring (30) is bent over as it ends and fitted on corresponding bearing pins (28).10. The transport roller according to claim 1, with which the spring (30) can be acted upon by a bolt (14).11. The transport roller according to claim 10, with which the bolt (14) is a component of the fixture (10) carrying the wheel (18).
