Technique: The usefulness of veerpootbruggen

Or strut bars, if you like.

Veerpootbruggen are those things that you have in some cars, side to side under the hood find These bars to connect as the name suggests the ends of the two struts to the top with each other. What is exactly the point of it? The most common reason for a veerpootbrug to install, is the increase of the stiffness of the car.

A few samples of cars that have such a thing at the factory (or of the huistuner of the relevant brand) were:

– BMW 125i Performance
The Volvo V60 Polestar
– BMW M4
– Toyota GT86 with TRD stuff

The technique is primarily used on cars with MacPherson struts. For the sake of completeness, here is a schematic representation of this type of suspension, where we are already, perhaps, once an article would have to devote to it. Note, in each case on the upper part (with the green disc) of the strut is the point of the strut bar is confirmed.

As soon as the wheel comes up -you drive over a bump, you take a turn with reasonable speed etc – is there also a reasonable pressure on the head of the strut. This can, in turn, slightly move relative to the other strut, but also in relation to the chassis. Therefore, the wheel position (also known as a camber change and that’s not desirable, as well as the necessary flexibility in the chassis. This can indeed go twisting and that’s not the intention.

The strut bar makes sure that such forces more evenly over both struts to be divided, so that the overall stiffness of the car slightly increases. It draws you scheurijzer this significantly more G’s in the faster turns? Not per se. The operation of the veerpootbrug depends to a large extent on the stiffness of the (front)wheel suspension and particularly with the suspension. MacPherson suspension is used primarily in cheaper, and therefore often also less fast cars. Consequently, suspension is not super stiff adjusted, which is the effect of a strut bar partly.

Where a veerpoogbrug is, however, useful is to increase the ‘feeling’. Despite the fact that the handling does not change significantly need to improve, it may well be that the director in question to better feel what the front assembly is exactly doing and especially about asphalt that is not super sleek. And that can of course again result in higher cornering and improved lap times and so on.

That a strut bar as stiff as possible and that, moreover, at any point, will not surprise. Weight is also a factor. The veerpootbrug is relatively high in the car and it’s less convenient for the centre of gravity. On the picture at the very top you will see, however, a construction of carbon fiber, that both the stiffness and weight a helping hand.

Conclusion

In daily commuting, or to the supermarket 3 km away, you will have little of the installation of a strut bar brands. At faster cornering in a car with stiffer suspension to a MacPherson setup, so it can indeed make a difference, especially in feel and not necessarily pure speed.
