Abstract: This invention is related to a service brake chamber manufactured with a composite pressure housing and a non-pressure housing, used in the air brake system of heavy vehicles such as trucks, trailers lorries and buses and a connection method of pressure housing and non-pressure housing forms this chamber.

Abstract: This invention is related to a diaphragm-diaphragm spring brake actuator with internal ventilation designed to decrease the actuator breakdowns used in the air brake system of heavy vehicles such as trucks lorries, trailers and busses.

Abstract: This invention is related to improving the sealing of the adapter plate inside the spring brake actuator and to improving the bearing of the intermediate shaft and the adapter plate. The invention is related to a new design regarding the bearing section providing sealing between the intermediate shaft and the adapter plate, which is a part of the spring brake actuator. The present invention is related to the development of two pieced bearing member having different hardness and being produced from different materials one of which is a rigid plastic piece which prevents force losses and decreases lateral loads, and the other of which is the rubber means.

Abstract: A non-detachable body connection with a connection ring which enables the non-detachable connection of the upper body located at the service part of the emergency brake cylinders used in the airbrake systems of heavy weight vehicles and the lower body parts located at the emergency section by using an additional piece during the coupling with adapter plate.

Abstract: This invention is related to the decrease of the breakdowns that occur in the actuators by means of the application of internal ventilation system to the diaphragm piston spring brake actuators which are used in vehicles such as truck, van, bus and trailer. The internally ventilated diaphragm-piston spring brake actuator that is developed by this invention is comprised by an aluminum piston, an aluminum pipe, a park chamber, a service chamber, a piston valve (6), a piston valve spring (7), inlet air openings (11), an air transition space, a plug (13), air inlet holes, a pneumatic sealing, an outlet channel characterized in that it has a valve (26) having sealing lips (27), sealing surface of piston valve (28) and a square or rectangular sectioned sealing member.
