Production Methods
The term ‘spring rate’ is used in order to define the ‘strength’ and ‘stability’ of a spring. The spring rate is made up of the variables: ‘Change in the force impacting on the coils’ for ‘Resulting change in the length’ of the spring. A spring with a constant ‘stability’ is described as a spring with a ‘linear characteristic curve’.
The term ‘spring rate’ is used in order to define the ‘strength’ and ‘stability’ of a spring.
The spring rate is made up of the variables: ‘Change in the force impacting on the coils’ for ‘Resulting change in the length’ of the spring. In the case of a spring with a progressive spring rate, the ‘stability’ of the spring increases, the more the spring is compromised.
The most important characteristic of this spring shape is that the wire diameter is always constant and the spring rate stays the same.
This type of spring shape is currently experiencing a reduction in its use, as further developed designs have advantages which are described below.
Side load (or banana) ‘springs’ are curved and when compressed, they develop a side force on the shock absorber, which greatly reduces the friction on the piston rod and seal.
This function improves the response of the shock absorber and increases the service life of the damper.
The most important characteristic of this spring shape is that the wire diameter is always different, i.e. inconstant, and as a result, the spring rate is very variable.
Each individual coil has a different ‘stability’ whereby, when compressed, the total strength of the spring progressively changes towards a load. The spring is stronger, the more pressure that is applied upon it.
The mini spring block has a barrel-shaped appearance and as a condition of the design, it always has to be produced with a variable (inconstant) wire diameter.
As a result, a perfect compact size is combined with progressive characteristics. The inconstantly cone-shaped and tapered wire diameter allows for full compression, without the coils being touched. This characteristic guarantees noise-free function under the vehicle and an extremely smooth ride.
