Parking Lock Actuator

KÜSTER moving smart!

We play it safe: A car must not only drive, it must also stand safely when it is not in use and is parked. We were one of the first developers and manufacturers worldwide to bring an electric parking brake onto the market - and have been continuously improving it ever since.

KÜSTER moving smart!

We play it safe: A car must not only drive, it must also stand safely when it is not in use and is parked. We were one of the first developers and manufacturers worldwide to bring an electric parking brake onto the market - and have been continuously improving it ever since.

Maximum security

Progressive even at a standstill

The innovative technology of our parking lock actuator ensures that parked cars are securely parked. Even with heavy vehicles parked on particularly sloping terrain, where enormous forces act on the system. Thanks to the special, patented design of the actuator, even heavy vibrations - for example on construction sites - do not affect the system. The lock remains firm and the vehicle remains secure and stable.
 

The facts:

It's the details that make the difference.

Patented design

A special feature of our parking lock actuator is the patented concept for the arrangement of the motor and gearbox. This enables a particularly compact design and therefore not only saves weight, but also takes up very little space.

The position sensor detects the exact position of the actuator at all times and makes our actuator extremely safe and robust.

The electronics meet the security requirements of ISO 21434.

More safety, more comfort

How the parking lock works

As soon as drive mode "P" is selected, the motor torque is transmitted to the actuator's output shaft via a self-locking worm gear. Its rotary movement engages the locking pawl in the vehicle gearbox and the vehicle is secured against rolling away.

  • 40° rotation of the output shaft 
  • High torque up to 22 Nm
  • Docking time of just 470 ms
  • Spring-mounted engine mount
  • Separate chamber for mechanics and electronics
  • Inductive sensor concept
  • Separate chamber for ECU IP 67
  • Lifetime of at least 300,000 actuation cycles
  • Mechanical transmission lock for combustion vehicles
  • Mechanical rotor lock on Elektor vehicles
Comfort at the touch of a button

Motor-over-caliper actuator

Whether in urban stop-and-go traffic or when driving uphill, the electric parking brake from KÜSTER provides noticeable comfort and maximum safety – the smart solution for modern parking.

  • Compact construction
  • High torque transfer
  • Convenient acoustic performance
  • Low cost
Our strength: the strength

High torque, maximum safety

When particularly heavy vehicles such as construction machinery, trucks or SUVs are parked on slopes, possibly even with a trailer, enormous forces are released. This is not a problem for our parking lock actuator, as it can withstand torques of up to 22 Nm. In addition, the motor is spring-mounted, which prevents the lock from "jumping out" even in the event of strong vibrations.

Future made by KÜSTER

Our innovative spirit is demonstrated by the fact that we were one of the first manufacturers worldwide to launch series production of the first electric parking brake back in 2002. Just one of many examples of our progressive thinking and actions.
