Embodiment Construction

[0030] figure 1 An example of a self-propelled machine F representing a paving machine F for processing asphalt and / or concrete paving materials in the production of overlays such as traffic surfaces or the like.

[0031] The machine F has a chassis 32 with undercarriage 33 (alternatively a tracked undercarriage) comprising wheels in the illustrated embodiment and an internal combustion engine M (for example a diesel engine) as a main drive source. Furthermore, the machine F has a plurality of functional components and operating components which are mainly operated hydraulically and are supplied with driving power from the internal combustion engine M. As shown in FIG. A hopper 36 is provided on the chassis 32 . A longitudinal conveyor 37 extends from the hopper 36 on the chassis 32 to the rear end of the chassis, where a transverse distribution assembly 38 with a height adjustment 47 and a drive 39 is located. A paving screed 34 is linked to the chassis 32 . The angle of ...

Abstract

The machine (F) has a setting and regulating device for setting operation temperature of hydraulic medium to about 60[deg] C. The hydraulic medium cooling region includes a cooler having a fan that is switched ON and OFF, while regulating the speed of fan. The hydraulic medium cooler is structurally separated from the cooling liquid cooling region. The fan is connected with the setting and regulating device. A thermostatic valve controlled by the setting and regulating device is arranged in the hydraulic circuit within a bypass deviating from the cooler.

Description

technical field [0001] The present invention relates to self-propelled machines. Background technique [0002] The drive principles for the functional and working components have been standardized for the machines, in particular paving machines and paving supply vehicles. The internal combustion engine serves as the main drive source, whereas the functional and working components are operated exclusively or almost exclusively hydraulically, for example by means of a hydrostatic drive unit. At least one covering layer having a variable width is laid on a plane by means of a paving machine which flattens and compacts the covering layer. The paving supply vehicle stores a sufficient quantity of paving material and supplies the paving material to the paving machine while the paving supplying vehicle and the paving machine being towed are traveling on a flat surface at a low operational travel speed, for example at a speed of about 20 m / min , so that the paver can work continu...
