6 GROUNDING SYSTEMS It feels good to be on the road with Schunk. Perfect protection. Schunk shaft grounding preserves motor and transmission components. The motor and transmission bearings of electric rail vehicles are often damaged by high-frequency currents. Shaft grounding provided by Schunk effectively protects against costly bearing damage and decisively reduces your maintenance outlay. Schunk shaft grounding systems with carbon fiber reliably draw stray shaft currents to vehicle ground. They thus protect roller bearings and neighboring components in transmissions and AC motors from damage. The unique structure in interwoven carbon fibers ensures optimum contact and high abrasion resistance. The Schunk shaft grounding system can be adapted to the traction motor on the bogie or to industrial plants, as required. Thanks to their compact dimensions, they can also be retrofitted without problems. An investment that quickly pays for itself. The major benefits of working with Schunk: This system prevents costly damage to bearings Rapid amortization through reduced maintenance and repair outlay Slim design allows use in compact installation situations on the bogie. Depending on the application: expensive coatings for bearings are no longer required Steadfast service. Grounding contacts from Schunk stand out with their long service lives. Grounding contacts must be reliable and must last as long as possible. Schunk offers you durable solutions for all current installation situations and interfaces. It s no coincidence that leading vehicle manufacturers ask for our grounding contacts and grounding brushes. After all, we revolutionized the transfer of signal currents with our carbon/carbon grounding contact and allowed new dimensions in maintenance intervals to be achieved. Meanwhile, our robust carbon/steel grounding contacts are ideal for standard applications. Both types stand out for low wear and for the particularly long life of the grounding brushes. Our extensive experience secures you the decisive edge when developing new vehicles. The major benefits of working with Schunk: Extremely long service life of all grounding contacts Variety of systems covers all current installation situations and interfaces High design and development competences Robust universal versions for applications in traction and industry Carbon brush for grounding contact Axial Grounding system for mounting on axle end Carbon/carbon grounding contact Carbon fibre grounding system for vagrant shaft currents Radial grounding system for mounting on gearbox 10 11

7 CARBON BRUSHES AND BRUSH HOLDERS WHEEL FLANGE LUBRICATION Power transmission perfected. Schunk carbon brushes and brush holders have been the driving force in electric motors for decades. The path of least resistance. Schunk wheel flange lubrication ensures profitability silently. Switches Brush holders for railway applications Conductor lines Contact sets Long-life carbon brushes for local transportation reduce maintenance outlay Stick for wheel flange lubrication Carbon brushes for regional traffic Contact levers For 100 years, Schunk Carbon Technology has been at the leading edge of carbon brush development. This knowhow will continue to take you forward in the future. Schunk carbon brushes stand out for their high electrical and thermal conductivity and long service life. They ensure optimal power transfer under all operating conditions. We also make brush holders, current braids and switch and breaker contacts. All components are produced in close cooperation with leading manufacturers or to your individual specifications. Our customized materials options mean we can satisfy even unusual requirements. When steel rolls on steel, friction and noise are generated. By applying Schunk flange lubrication, you measurably reduce wear and operating costs. And the annoying squeaky noise is reduced to a minimum. The principle of Schunk flange lubrication is simple: a carbon-based dry lubricant reduces the frictional forces between flange and rail. This is achieved by fitting a holder and a lubricant nipple directly to the bogie. The nipple is pressed against the flange by a spring and ensures constant lubrication at the correct dosage. The result is significantly reduced wear and thus also a longer service life for both wheels and rails. The major benefits of working with Schunk: Low investment costs Economical consumption using dry lubricant Low wear to wheels and rails Simple to maintain and repair Environmentally friendly: reduced traction energy required, no oil on the tracks and less running noise Schunk s material competence means optimized solutions for all requirements 12 13
