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 wet-dry room seperation 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 systems

Door components

Systems for liftgates

Drives for side doors

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

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

Modular principle for high robustness in all models and load ranges
Design as a one or two-sided spindle drive or push rod possible
Installation in the rainwater duct or under the roof
Integration of brake and overload clutch possible
Noise level below 45 dB(A)
Mechanical power from 33 to 43 W

Utilization of standard components for cost savings
Modular kit approach for high robustness and flexibility
Small package
Design with internal torque support
Plug & Play solution for manual decklids

Very low standby current consumption under 170 μA
New, more compact generation of electronics with sensor chip for improved sensitivity and same level of insusceptibility to environmental influences
High robustness through the use of standardized components

Best opening acoustics achieved through gearless power opening with cord actuator
Up to 150 g weight savings per door compared to competitors
Function and package space requirements customizable

The Brose system comprises:
(1) liftgate drive
(2) sensors
(3) latch with (4) power cinching unit
(5) control unit
(6) obstacle detection sensor

Scalable electronic functional scope at different levels, e.g. sensors, auto-down, anti-trap feature, PWM control
Variants from 8 to 14 Nm for wet and dry side applications
Weight from 270 g

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

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

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

60 g weight saving compared to previous generation
Optimized for high-volume production and global usage
Insusceptible to environmental influences
Further development of the proven spring clutch

Power opening and closing of even heavy doors in angled positions and on slopes
Integrated variable door check with zero-current brake
Attached to conventional structural interfaces, can thereby be offered as an optional feature
Modular design for flexible use and shorter development periods
