An application for a new type of pneumatic engine concept

Abstrakt

Heavy trucks are often equipped with loading and unloading systems like dock levellers with swing lip or telescopic lip. Most of these devices require hydro-electrical energy supply systems (eg. the pump that presses the working substance to the actuators must be propelled by electric engine.) The space taken by pump with electric engine can be reduced on condition that a new type of pneumatic drive will be considered. It is possible to supply pneumatic engine from air supply system that is existing on the board of transport vehicle which is a part of brake system. In addition, this solution allows for the use of compressed air energy stored earlier in the accumulation tank. Platform longitudinal movement that is provided by linear hydraulic cylinders also can be achieved with use of rotary pneumatic motor and simple linear gear units. For the other type of platforms engine rotational movement is converted to lip swing movement with usage of ropes or chains. The proposed concept assumes that the drive of the loading and unloading equipment is provided by a high-torque pneumatic engine which works in the reversed cycle of the tooth compressor and is propelled by compressed air directly from the truck's braking system. The reversal of the tooth compressor cycle is possible by attaching the discharge window of the compressor to the pressured tank with air. Such modification causes that suction window of the compressor becomes the outlet of the air and then tooth compressor is operated as a pneumatic engine.
