AI Technical Summary

Technical Problem

Existing connecting methods between vehicle components, such as axle and motor supports, suffer from micromovements due to corrosion protection coatings, leading to complex and expensive solutions like interlocking profiles or elastic bearings, which are not cost-effective.

Method used

A connecting element with elevations that dig into the contact surfaces of components, creating a positive and non-positive connection to prevent micromovements, allowing for a firm fit without over-tightening the screw connection.

Benefits of technology

The solution provides a simple and cost-effective method to eliminate micromovements by using elevations that penetrate into the contact surfaces, ensuring a firm connection without over-tightening, thus preventing unwanted movement between components.

Abstract

The invention relates to a connecting element (18) for the play-free connection of two components, which has a first connecting surface (20) which, in the connected state, bears against a contact surface of one of the components, and a second connecting surface (24) which, in the connected state, bears against a contact surface of the other component, wherein the first connecting surface (20) and / or the second connecting surface (24) has at least one elevation (32) which, in the connected state, digs into the contact surface of one of the components, so that a positive and non-positive connection is created between the component and the connecting element (18). Furthermore, the invention relates to a vehicle having at least two components which are screwed together, wherein at least one such connecting element (18) is arranged between the components.

Claims

[1] Connecting element (18) for the play-free connection of two components (11), which has a first connecting surface (20) which, in the connected state, bears against a contact surface (22) of one of the components (11), and a second connecting surface (24) which, in the connected state, bears against a contact surface (22) of the other component (11), wherein the first connecting surface (20) and / or the second connecting surface (24) has at least one elevation (32) which, in the connected state, digs into the contact surface (22) of one of the components (11), so that a positive and non-positive connection is created between the component (11) and the connecting element (18). [2] Connecting element according to claim 1, characterized by that each connecting surface (20, 24) has at least three elevations (32). [3] Connecting element according to claim 1 or 2, characterized by that the at least one elevation (32) is designed as a circular elevation (32). [4] Connecting element according to one of the preceding claims, characterized by that the at least one elevation (32) has a height between 0.4 mm and 0.6 mm. [5] Connecting element according to one of the preceding claims, characterized by that the connecting element (18) is designed as a disc. [6] Connecting element according to one of the preceding claims, characterized by that the connecting element (18) has a thickness between 1 mm and 2 mm. [7] Connecting element according to one of the preceding claims, characterized by that the connecting element (18) has a diameter between 30 mm and 40 mm. [8] Connecting element according to one of the preceding claims, characterized by that the connecting element (18) has a through-opening (28) for passing through a screw element (16) in order to screw the components (11) and the connecting element (18) together. [9] Connecting element according to one of the preceding claims, characterized by that the connecting element (18) has at least one fastening opening (30) for passing through a fastening element in order to fasten the connecting element (18) to one of the components (11). [10] Vehicle (10) comprising at least two components (11) which are screwed together, wherein at least one connecting element (18) according to one of claims 1 to 9 is arranged between the components (11).
