Several sensors or actuators can be reached with a single sheathed cable. For example, a multicore sheathed cable is laid from the chassis to the wheel carrier for a front axle and only then distributed accordingly. This not only saves space, but also cuts costs.
There are many terms in the industry for wheel arch harnesses: They are also known as wheel arch wiring, axle wiring, or speed sensor cables. But whatever you want to call them, the key issue mostly concerns safety. Safety. It all began with the first cable harness for the anti-lock braking system. That has been supplemented over the last few decades to include ESP, shock absorber adjustment, electronically controlled suspension, brake lining wear monitoring, electric parking brakes, tire pressure monitoring systems, and a host of other features. The scope of these functions will continue to grow in the future, for example through highly automated driving, HAD for short. WeWire provides innovative installation solutions in the cramped installation space of a wheel arch.
Wire harnesses in wheel arches are exposed to constant loads. At the front axle, they not only have to deal with dynamic loads caused by the suspension system, but the steering movements as well. However, it’s not only the uneven road surfaces and curves that put so much strain on wheel arch harnesses; environmental influences also play a key role. This is where the right material is key, because the wires need to function reliably, even at extreme below-zero temperatures. To resist the dynamic loads that they are exposed to when driving, the wires need to be routed with great precision, may not come into contact with other components and may not be exposed to tension. We faced these challenges at a very early stage and are constantly taking advantage of the already very cramped installation space. That is the reason why we are a technology leader in the field of wheel arch harnesses today.
