Telescopic Actuating Unit for Tilting Vehicle Main Stand
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing main stands for tilting vehicles often interfere with the user's foot or leg area when operating, as the actuating units extend in a direction that collides with the user during the tilting process, posing a risk of impairment.
Innovation Solution
The actuating unit is designed to be telescopic, allowing it to move from a rest position to an actuation position through translational movement, reducing its extent transversely to the longitudinal direction of the support element, and featuring a hinge mechanism with an offset axis of rotation and stop to ensure secure positioning, preventing collisions and facilitating easy operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the actuating unit extends obliquely or transversely away from the support element to enable easy movement into the support position, then the ease of operation is improved, but the actuating unit collides with the user's foot or leg area during operation
Solution Approach 1:
The actuating unit is designed to be dynamically adjustable in its extension length through a telescopic structure with fixed and movable actuating elements. The extension length can be adapted according to different operating conditions, allowing the unit to extend sufficiently for effective operation while retracting to avoid collision with the user's foot or leg area during vehicle operation
Solution Approach 2:
The extension length of the actuating unit is changed as a variable parameter. By adjusting the extension length of the telescopic actuating unit, the system optimizes between two conflicting requirements: sufficient extension for effective leverage when actuating the main stand, and reduced extension to avoid interfering with the user's foot or leg area during vehicle operation
2Productivity
If the actuating unit is extended to provide sufficient leverage for jacking up the vehicle, then the productivity is improved, but the extent transverse to the longitudinal direction of the support element increases causing collision risk
Solution Approach 1:
The telescopic actuating unit provides dynamic adjustment of its extension length, allowing the system to achieve sufficient leverage for effective vehicle jacking when needed, while maintaining the capability to reduce its transverse extent to avoid collision with the user's foot or leg area during normal vehicle operation
Solution Approach 2:
The extension length parameter of the actuating unit is varied to optimize performance. When jacking up the vehicle, the actuating unit is extended to provide sufficient leverage for effective operation. During normal driving, the extension length is reduced to minimize the transverse extent and prevent collision with the user's foot or leg area
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design allows for safe and efficient operation by preventing collisions with the user's foot or leg area while enabling effective transfer of the support element from a basic to a support position, providing favorable lever ratios for jacking and ensuring high torque transmission.
Implementation Method 1
the movable actuating element and the stationary actuating element are designed to be telescopically extendable into one another, whereby the actuating unit can be moved into the actuating position at least by a translational movement
Implementation Method 2
the actuating unit comprises a hinge means which is arranged between the stationary actuating element and the movable actuating element, which includes the axis of rotation and by which the movable actuating element can be rotated about the axis of rotation
Implementation Method 3
the hinge means comprises at least one stop which at least limits the movement of the movable actuating element from the rest position to the actuating position when the actuating position is reached

AI summary
The invention relates to a main stand (2) for a tilting vehicle (4), comprising at least one support element (6) that is rotatably secured or can be rotatably secured to a support structure (8) of the tilting vehicle (4) and can be converted from a support position, in which a contact section (10) of the support element (6) rests or can rest against the ground and in which the tilting vehicle (4) is kept from carrying out a movement, in particular overturning, by means of the support element (6), into a base position, in which the support element (6) is arranged at a distance from the ground so as to not contact same, and comprising at least one actuation unit (12) that is secured or can be secured directly or indirectly to the support element (6) and in an at least partly movable manner relative to the support element (6) and can be converted from a rest position, in which the extension of the actuation unit (12), when viewed transversely to the length of the support element (6), is minimal, into an actuation position, in which the extension of the actuation unit (12), when viewed transversely to the length of the support element (6), is maximal and in which the actuation unit can be actuated by a user of the tilting vehicle (4) in order to convert the support element (6) from the base position into the support position.
