Solution Overview
Problem
Existing braking and/or clamping devices face challenges in achieving a simple, space-saving design with high clamping forces, short reaction times, precise positioning, and maintenance-free operation.

A braking and/or clamping device with a longitudinally displaceable central body that supports spline gears and spring accumulators, arranged alternately in the circumferential direction, allowing for efficient absorption of clamping forces and minimizing the housing's load, while using various actuators for loading and unloading directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the spline gears and spring accumulators are arranged one behind the other in the longitudinal direction of the guide, then the device structure is simplified, but the device occupies more longitudinal space and the housing has to support larger longitudinal forces
Solution Approach 1:
The patent transitions from a longitudinal arrangement (one behind the other) to a circumferential arrangement (side by side) of the spline gears and spring accumulators. This dimensional change allows the components to be distributed around the guide rail in the circumferential direction, reducing the longitudinal footprint while maintaining structural simplicity.
2Force
If the clamping forces are absorbed by the housing, then the housing structure must be reinforced, but this increases the weight and complexity of the housing
Solution Approach 1:
The patent extracts the clamping force absorption function from the housing and transfers it to a dedicated central body. The central body is specifically designed to support the spline gears and spring accumulators and absorb the radial clamping forces, while the housing is relieved of this heavy loading, reducing its weight and structural complexity.
3Measurement precision
If the friction blocks are actuated via spline gear with roller bearings, then the positioning precision is improved, but the device requires more maintenance
Solution Approach 1:
The patent employs self-lubricating materials for the roller bearings in the spline gear mechanism. This allows the bearings to maintain their lubrication without external intervention, enabling the device to maintain precise positioning while requiring minimal maintenance. The self-service characteristic eliminates the need for periodic lubrication replenishment.

Function Achieved in This Case
The solution enables high clamping forces, short reaction times, precise positioning, and maintenance-free operation, with the central body effectively managing clamping forces and reducing the load on the housing, resulting in a robust and efficient braking and/or clamping mechanism.
Implementation Method 1
the spline gears can be driven for loading and relieving the friction block per loading and relieving direction by means of at least one actuator and/or by means of at least one spring accumulator
Implementation Method 2
