| Summary: | The new rolling roof fairing installed in the tractor non-bonnet cab main train layout constructing are given. After analyzing
existing exhausting elements installed on the tractor highway trailer and a large number of roof rails, it has been substantiated
the expediency of installing a movable rope on the tractor roof, which can change the angle of the trailer airflow link with the
combination of two movements - vertical and horizontal. The combination of these movements enables to change the parameters
of streamline. For this purpose, the basic hydraulic control scheme is designed, which has a number of advantages:
the starting units movements smoothness, the ability to continuously adjust the speed in a wide range, low inertia, simplicity
of management and automation, high operational reliability and resistance to overload. Due to the modern capabilities and
development of sophisticated electronic control systems through the introduction of such a system in the control process of
hydraulic cylinders can ensure the system reliability, efficiency, ergonomics and safety equipment. |
