Clutch cylinders for trucks and buses
The DT Spare Parts brand offers a complete range with more than 30 000 different spare parts for trucks, trailers and buses, including all standard clutch cylinders.
Clutch cylinders are hydraulic master cylinders. Combined with a reservoir for the operating fluid, they serve to transmit power from the clutch pedal to the subsequent downstream components of the hydraulic clutch actuation system.
Actuation of the clutch pedal moves a piston. This compresses a fluid and so converts the mechanical power into hydraulic power. The thus generated pressure change in the cylinder is transferred by a line to the clutch servo (slave cylinder).
In vehicles with automatic transmission, the clutch cylinders are additionally equipped with shift point and travel sensors.
The cylinder bores are specially honed. This keeps wear on the piston sealing components to a minimum.
The sealing components in the cylinder are adapted to the pressure medium to be used. The nature of the medium to be used is specified on each DT clutch cylinder.
Plastic pistons are internally reinforced with a metallic cap.
In order to increase the service life, the plastic eyelet on the push rod is additionally reinforced with glass fibre.
DT Spare Parts brand clutch cylinders undergo numerous tests. These include, for instance, the test of hardness of mouldings and inspection of the quality of the honed inner running surface, as well as the test of tightness and functionality of the cylinder at high humidity levels and extreme temperatures ranges (-42°C to +85°C).
Construction of ABS sensors
In addition to clutch cylinders, the comprehensive DT range includes all matching repair kits, as well as all standard clutch servos and the corresponding hose assemblies.
