ELC Case

Task

The level of a truck trailer is to be controlled by air springs, for example when the trailer is unevenly loaded or takes a curve. The system is designed to compensate for the "misalignment".

Solution

KKI pneumatic valve bodies made of plastic replace the currently used aluminum valve bodies. The valve bodies regulate actively and dynamically the air supply of the air springs. The trailer height is constantly monitored and maintained at the desired position and level.
No mechanical rework is needed on the valve body.

Your Benefits

  • No corrosion
  • Reduction of system weight
  • Reduction of costs
  • Active increase of road safety (by centering the vehicle's balance point)
  • KKI mounts all additional components such as silencers, screw sleeves, ultrasonic-welded covers and checks component leakage.

POS Case

Task

For parking and maneuvering a truck trailer, a system is required which opens, closes and controls the compressed-air brakes.

Solution

KKI pneumatic valve bodies made of plastic replace the currently used aluminum valve bodies. The valve bodies control the air supply to the compressed-air brakes.
The trailer can be parked and maneuvered with the highest degree of safety and precision.
No mechanical rework is required on the valve bodies.

Your Benefits

  • No corrosion
  • Reduction of system weight
  • Reduction of costs
  • KKI ultrasonically welds the covers to the valve body and checks the component for leakage.

Locking Bracket

Task

A bracket with corresponding locking contour is inserted into the transmission to prevent the axial movement of non-activated shift forks. This comes into play when the shift fork lock fails. For this purpose, a sheet metal bending component is used, which is very costly to manufacture and requires several processing steps.

Solution

The KKI locking bracket replaces the previously used sheet metal bending component. To manufacture the component by injection molding, the existing component was re-engineered to adopt a design compatible with injection molding. This polymer solution not only reduces the weight but also enables single-process production. The sheet metal bending part, in contrast, had to be produced in several steps.

In addition, the polymer solution has the advantage that the component can be used in several transmission types through appropriate optimization.

Your Benefits

  • Dimensionally stable construction material
  • Resistant to oils
  • Thermal expansion coefficient close to aluminum
  • Significant weight savings
