Bearing Assembly Locking Pin for Tipper Trailer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bearing arrangements for vehicles with tipper trailers, particularly two-way or three-way tippers, require improved locking mechanisms for operational safety and user convenience, as current axial socket pin locks necessitate two-handed operation and additional security measures.
Innovation Solution
A locking pin with an integrated actuating element and locking element, allowing one-handed operation by pivoting the handle section to secure and release the locking position, eliminating the need for additional components like spring pins, while also incorporating a damping element in ball tilting bearings to reduce noise and wear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If axial locking pins with spring clips are used to secure bearing components, then operational safety and reliability are improved, but ease of operation deteriorates as two-handed operation is required
Solution Approach 1:
The patent combines the locking pin and spring clip into a single integrated locking element. The spring clip is attached directly to the locking pin, forming one unified component that performs both locking and securing functions simultaneously, eliminating the need for separate components and two-handed operation
Solution Approach 2:
The integrated locking element uses the spring's elastic force to automatically engage and secure the locking pin in place. The spring clip leverages its own elastic deformation to provide the securing action, making the system self-securing without requiring additional manual intervention or separate securing components
2Reliability
If additional security components like spring clips on chains are added to prevent unintentional release, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent merges the locking pin and spring clip into a single integrated component. The spring clip is directly attached to the locking pin, forming one unified element that provides both locking and securing functions, thereby reducing the total number of components while maintaining double-locking security
Solution Approach 2:
The integrated locking element serves multiple functions simultaneously: it provides the primary locking action through the locking pin, and provides the secondary securing action through the attached spring clip. This multi-functional design eliminates the need for separate security components, reducing overall device complexity

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables secure, one-handed operation of the bearing arrangement without compromising safety or reliability, and reduces noise and wear in ball tilting bearings through the use of a damping element, enhancing the overall user experience and operational efficiency.
Implementation Method 1
an initial position in which the locking element and the actuating element are not interacting with each other, in particular by means of an elastic element (140)
Implementation Method 2
incorporating a damping element in ball tilting bearings to reduce noise and wear

AI summary
The present invention relates to a bearing arrangement for a vehicle with a tipper trailer, comprising a first bearing part (110) which can be assigned to a frame (R) of the vehicle, a second bearing part (120) which can be assigned to the tipper trailer (K), wherein the first (110) and the second (120) bearing part are provided to enable a pivoting movement of the tipper trailer (K) relative to the frame (R) of the vehicle about at least one inner pivot axis (A) in a connected state, and a releasable locking pin (130) which, in a locking position, interacts with the first (110) and the second (120) bearing part in such a way that the connected state of the first (110) and second (120) bearing part is fixed.According to the invention, the locking pin (130) comprises an actuating element (132, 136) which, when actuated by a user, enables the locking pin (130) to be released from the locking position and thus the connected state to be released, wherein a locking element (118) is further assigned to the first (110) or the second (120) bearing part, wherein the locking pin (130) can be moved into or out of a locking position while maintaining the locking, in which the locking element (118) and the actuating element (132, 136) interact in such a way that actuation of the actuating element (132, 136) is prevented.
