Drive arrangement, in particular for the material pumps of road-marking machines or the like

摘要

The invention relates to a drive arrangement, in particular for the pump for supplying marking material to the discharge members in road-marking machines or the like, and has the aim, in particular in the case of road-marking machines, to achieve, using only one material pump, a very rapid adaptation of the delivery rate of this pump for feeding the discharge members with different, rapidly changing material quantities. For this purpose, it is proposed according to the invention to arrange hydrostatic power transmission means, consisting of oil pumps and oil motors which can be abruptly reversed and/or switched on and off, between a path-dependent drive source proportional to the travelling speed and the material pump (Fig. 1).
