铺路机及方法
摘要：
一种铺路机(F)包括主驱动总成(P)的内燃机(M)尤其是柴油机发动机、由具有包括行进泵总成(23)的液压泵(23，30-33)的功能单元，该功能单元由内燃机(M)驱动以向至少一个行进驱动装置(16)供能，以及用于向铺路机(F)上和/或铺路机(F)的铺路刮板(B)上的电加热装置(H)提供电力的发电机(G)，发电机(G)得到永久驱动同时至少一个泵(23，30-33)可以经由至少一个可变换离合器(K1，K2，K3)选择性与内燃机脱开。在电加热装置(H)经由得到永久驱动的发电机(G)的热启动过程中，至少一个泵脱开。在运输行进过程中，除了得到永久驱动的行进泵总成(23)和发电机(G)，功能单元的至少一个泵脱开。在内燃机(M)的起动过程中，以及选择地热启动过程中，功能单元的泵选择地包括行进泵总成(23)脱开。
摘要（英）：

In a paver F comprising a combustion engine M, in particular a diesel engine, of a primary driving aggregate P, functional units having hydraulic pumps 23, 30 to 33 inclusive a travel pump aggregate 23 which can be driven by the combustion engine M for supplying at least one travel drive 16, a generator G for supplying electric heating devices H of the paver F and/or of a paving screed B of the paver F with electric power, the generator G is driven permanently while at least one pump 23, 30 to 33 selectively can be disconnected from the combustion engine via at least one shiftable clutch K1, K2, K3. During a heating-up phase of electric heating devices H via the permanently driven generator G at least one of the pumps is disconnected. During transport travel at least one pump of the functional units, except the permanently driven travel pump aggregate 23 and the generator G, is disconnected. During start and, optionally, during warm-up of the combustion engine M pumps of functional units, optionally including the travel pump aggregate 23, are disconnected.
