Tilting Cab Supply Line Layout With Rear Connector Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for routing supply lines in tilting cabs of commercial vehicles suffer from mechanical stress, inefficient routing, and space constraints, particularly around the pivoting axis, and fail to provide a reliable connection, which can lead to fatigue and increased production costs, and mechanical stress during each tilting operation, which can lead to cable run long, and mechanical stress during each operation, which can lead to fatigue and increased mechanical stress during each tilting operation, which can lead to fatigue and increased mechanical stress during each tilting operation.
Innovation Solution
The solution involves a commercial vehicle with a chassis, a cab, and a tilting mechanism, where supply lines are divided into sections on the chassis and cab, connected by a detachable connecting device, preferably located in the rear half of the cab, allowing automated or manual disconnection and connection, and featuring sensors and locking mechanisms to ensure safe and efficient tilting operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If supply lines are routed over the tilting axis to allow cab tilting, then the cab can be tilted for maintenance work, but the cable run becomes long and production costs increase
Solution Approach 1:
The supply line system is segmented into a first section on the chassis and a second section on the cab, connected by a detachable connecting device. This segmentation allows the supply lines to be shorter while maintaining cab tilting capability, as the connections are made at the rear of the cab rather than routing lines over the tilting axis.
2Ease of operation
If supply lines are routed over the tilting axis, then the cab can be tilted, but mechanical stress during each tilting operation leads to fatigue
Solution Approach 1:
By segmenting the supply line system with detachable connections at the rear of the cab, the invention eliminates mechanical stress on continuous lines during tilting operations. The connecting device allows the cab to tilt freely without subjecting supply lines to repeated mechanical stress that would cause fatigue.
3Ease of operation
If supply lines are routed over the tilting axis, then the cab can be tilted, but installation space in the tilting axis area is constrained
Solution Approach 1:
The connecting device is extracted from the tilting axis area and positioned at the rear of the cab. This removes the supply line routing from the constrained tilting axis area, freeing up installation space while maintaining cab tilting functionality through the relocated connection point.

AI summary
The invention relates to a commercial vehicle comprising a vehicle chassis, a driver's cab, and a tilting mechanism by means of which the driver's cab is mounted to tilt. The commercial vehicle includes at least one supply line, wherein the supply line has a first section arranged on the vehicle chassis and a second section arranged on the driver's cab. The commercial vehicle further includes a connecting device for detachably connecting the first and second sections, wherein a cab-side part of the connecting device is arranged in a rear half, preferably in a rear third, and more preferably in a rear end region, of the driver's cab.
