摘要： In a transmission for a steerable drive wheel (4) of a forklift, which transmission is pivotable around a vertical axle (8) and contains a spur gear stage (24, 26) and a second reduction stage formed by a pinion shaft (28, 30) and a bevel wheel (36), the second reduction stage is designed as hypoid wheel set (30, 36) with positive axle offset. Unlike the designs known already, it is hereby possible, by adhering to preset limits of the outer dimensions and a preset reduction ratio, to obtain a toothing of more supporting capacity and a thicker pinion shaft (28) so that the loads of the tooth flanks are canceled and it is possible to use a design of a high loaded pinion bearing (34) having more supporting capacity.
