Description

Like the Bowden cables, the push-pull cable consists of a multi-layer construction of a pressure-resistant guide sheath, also called outer sheath, guide tube or jacket. The guide sheath consists of the inner tube, a wire mesh with support wire armoring which surrounds the inner tube and a cover layer of plastic which protects the construction from environmental influences.

Technical structure:

The inner tube made of plastic is used to guide the inner cable (for push-pull cables usually a wire rope with flat band armoring) and prevents the metal from rubbing against metal. This guide tube is reinforced with a metal wire to absorb higher forces and increase the service life of the cable. The metal wire here consists of round wires. In the most technically sophisticated version of the Bowden cable, the wires are also placed around the inner tube at a certain impact angle and reinforced with a support wire.

Construction with support wire reinforcement:This high-quality version of the Bowden cable, the push-pull cable, is used, for example, for gear selection in manual transmissions in vehiclesKey technical data:

In practice the following standards have emerged.

 
Advantages of the Bowden cable immediately:

>> High efficiency
>> Complex installation possible
>> Very robust
>> Transmission of compressive and tensile forces
>> Long service life
>> No maintenance necessary
>> Absorbs high environmental pollution
>> High modularity

Special solutions, which negate the above-mentioned values are of course possible, just contact us and we will support you with a specific solution.

Our push pull controls are custom built to meet your needs. Cable material, cable type, inner assemblies, outer conduits, stroke/travel, and other features can be tailored to your specifications. Conduit liners, lubricated inner members, actuation springs, and other additional components can also be added.
