Modular Door Drive with Universal Motor Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing drive devices for passenger transport vehicles, particularly those with pivoting sliding doors, face challenges in compact installation due to limited space around door openings, requiring specific component arrangements and increasing production and maintenance costs.
Innovation Solution
A drive device with a linearly movable runner and a motor attached to the vehicle or the runner, featuring multiple attachment options for the motor and gear, allowing flexible arrangement and reducing the variety of components needed, including a carrier with guide rails and a universal joint for efficient movement and locking mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a specific arrangement relationship between motor and gear is used for each installation situation, then the door drive can be properly installed, but the production and storage costs increase due to the need for specific components
Solution Approach 1:
The motor is designed with multiple mounting options that allow it to be installed in different positions (above or below the door opening) using the same motor unit. The carrier assembly provides universal mounting capability with multiple attachment points, enabling a single motor design to serve multiple installation configurations without requiring variant components
2Adaptability or versatility
If the motor moves with the runner, then the drive configuration is flexible, but the electrical wiring becomes more complex
Solution Approach 1:
The motor is extracted from the moving runner assembly and fixed to the stationary carrier, which is itself fixed to the vehicle body. This separation allows the motor to remain stationary while the runner moves independently, simplifying electrical connections as the motor can be wired to a fixed power source rather than requiring flexible wiring to a moving component
3Reliability
If multiple specific components are manufactured for each installation situation, then proper installation is achieved, but component diversity and storage requirements increase
Solution Approach 1:
A single universal motor unit with multiple mounting options replaces the need for multiple situation-specific motor variants. The carrier assembly serves as a universal mounting structure that can accommodate the motor in different positions, eliminating the need to manufacture and store multiple component variants for different installation scenarios

AI summary
The invention relates to a drive device for a sliding door or a sliding plug door of a passenger transportation vehicle, comprising at least one at least linearly movable runner (7) in order to move a door leaf fastened thereto, a motor (3) fastened to the runner (7) or to the passenger transportation vehicle, and a first gearbox (2, 5, 6) between the motor (3) and runner (7) in order to effect at least the longitudinal displacement of the runner, characterized in that at least two fastening options (13, 14), which differ in the arrangement ratios of the first gearbox and motor, are provided between the motor and the first gearbox.
