In a road-paving machine (1) with a tyred running gear, which has a longitudinally continuous material conveying section (9), a central drive motor/pump aggregate (14, 15) and steerable front wheels (5) as well as driven rear wheels (6, 7) on a substructure (8), and in which a hydrostatic rear-wheel drive device (16) with at least one hydro-adjusting motor (21), at least one switching gear which can be switched over between extremely slow working travel and rapid transport travel, and a multi-stage reduction gear, which drives each rear wheel (6, 7) directly, with at least one planet wheel set (46, 47, 48) are provided, the rear wheel drive device (16) has for each machine side an individual hydrostatic drive unit (17a, 17b) with a hydro-adjusting motor (21), a planet wheel switching gear (23) and the planet wheel set (46, 47, 48) built into the rear wheel (6, 7), each hydrostatic drive unit (17a, 17b) engages over the edge region (27, 28) of the material conveying section (9) from the outside, and an intermediate spacing (36) is provided in the transverse direction between both hydrostatic drive units (17a, 17b). <IMAGE> |
