Systems for vehicle doors and liftgates

The “crank drive for lowerable windows” marked the start of Brose’s innovation success. We also developed and produced the world’s first door system. Then we added closure systems, electronics as well as sensor technology to the portfolio and applied our expertise to the vehicle access. Brose opens up completely new dimensions of comfort with drives for side doors and liftgates that open and close automatically.

Door system with plastic carrier plate

  • Scalable product and integration scopes (window regulator rails, soundbox, fasteners)
  • Carriers available in fiber-reinforced plastics
  • Endless fiber-reinforced plastics reduce weight in the vehicle and have a positive effect on crash behavior in the door

#
#

Compact module

  • Plastic window regulator with wet-dry room seperation function as a module
  • Weight savings of up to 2 kg per vehicle compared to conventional component design
  • Integration of interfaces for further components such as loudspeaker, crash sensor and door control unit possible

Cable window regulator

  • Single or double-guided window regulator with steel, aluminum or plastic guide rails
  • Short development times thanks to high degree of standardization
  • Modular solutions for customer-oriented setting concepts for window regulators for frameless doors

#
#
#
#
#

Door control unit

  • Control of drives for window regulators with anti-trap feature, side mirror and latch
  • Control with standardized interfaces to the window regulator drive
  • Control of side door drives
  • CAN or LIN interface

#
#
#
#
#

Latch module

  • Integrated system for optimal function
  • Integration of additional functions such as window guides and theft-protection
  • All components in a pre-tested, ready-to-fit delivery unit
  • Door assembly therefore reduced by 90 seconds compared to installation of components
