摘要： The present invention relates to a road paver, particularly a small road paver, for paving a subbase layer in a working direction (a), with a machine frame, a traveling mechanism, a material hopper for receiving paving material, a paving screed for smoothing and compacting the paving material, a transverse distribution device for distributing paving material in the working direction (a) in front of the paving screed and transversely to the working direction (a), the transverse distribution device being supported at the machine frame via a support housing, and a height adjustment device for vertical adjustment of the transverse distribution device relative to the machine frame, wherein the support housing is supported at the machine frame such that it is height-adjustable via a quick coupling apparatus, wherein the quick coupling apparatus comprises at least one oblong hole with an expanded insertion portion and a sliding device, wherein the sliding device can be inserted into the oblong hole through the expanded insertion portion, and wherein the sliding device in the inserted state slides in the region of the oblong hole outside the expanded insertion portion during vertical adjustment of the transverse distribution device through the height adjustment device, and wherein the sliding device is supported in a form-closed manner in a direction perpendicular to the height adjustment in this region. Moreover, the invention relates to a method for mounting a transverse distribution device on a road paver.
