We received many inquiriesHeight-adjustable suspension for CX-8Has been released.We pursued handling with a sense of unity that does not make you feel a heavy-duty SUV, and we are proud that the product has a quick follow-up of the car and a suppressed roll feeling when turning corners.

The key to the ride is the characteristics of the damper.If you aim to run at will, such as in winding, the most important item is to quickly raise the damping force in the very low speed range (initial roll range in the figure) where the piston speed is 0.05 m / s or less at the moment when the damper starts to move. is.
If the rise of Coco is delayed, the damping force at the beginning of steering and the moment when the roll starts will be insufficient, and you will feel a glaring and unstable behavior.

However, it is extremely difficult to raise the damping force in this area according to the design value.Not only the accuracy of the piston, but also the friction of the sliding parts, the viscosity of the oil, and the riding comfort when the piston speed increases must be taken into consideration, so it is not straightforward.

Damping characteristics according to the design value, that is, what we wantThe method selected to achieve a comfortable ride is the fixed damping force type.I will explain the advantage with a conceptual diagram.By the way, the figure shows the state where the damper is about to stretch.Red lineIs the flow of oil.

<Fixed damping force>　Since it is as simple as the oil path ①, oil resistance is generated from the very low speed range at the moment when it starts moving, and the damping force rises without waste.

<Adjustable damping force>　In addition to the oil path ①, there is an adjustment path ②.Even if the damping force adjustment needle is fully closed, a small amount of oil leaks from a small clearance, so there is not enough resistance to the oil and there is a delay in the rise of the damping force.

There are no flashy specs to decorate the catalog, but the adoption of fixed dampers to achieve a ride suitable for "The Sports Limousine" is our commitment to AutoExe.

The KG-06 demo car with the same suspension will be available this weekendShonan Mazda Yokosuka storeIt will also be exhibited at the sports fair of.The person in charge of development is also resident for two days, and we also hold tuning consultation meetings.Please come by all means!
