Description

The invention relates to a fastening element for a component, in particular a carrier component, such as, for example, a body component of a vehicle. The invention also relates to a device for compensating for tolerances between two components to be connected.

Such a device for compensating for tolerances is generally known and is used in particular in automobile construction and is used to compensate for a distance between these components when connecting two components due to manufacturing or assembly tolerances, for example. Such a device comprises a fastening element for one of the components and a connecting element engaging in this, in particular a connecting bolt or a connecting screw, of the other component.

The object of the present invention is to specify a fastening element and a tolerance compensation device which enable the fastening element to be used multiple times.

According to the invention, the object is achieved with a fastening element having the features of claim 1. With regard to the tolerance compensation device, the object is achieved according to the invention by the features of patent claim 11.

Advantageous further developments of the invention are the subject of the dependent claims.

The fastening element according to the invention comprises a fastening section for a component, in particular for a carrier component of a vehicle, the fastening section having a receptacle in which a spring element is arranged that is axially fixedly connected to an inside of the receptacle in both directions.

The advantages achieved with the invention are in particular that such a spring element axially fixed in both directions within the fastening section in the receptacle transmits forces such as insertion and removal forces, in particular compressive or tensile forces, axially in both directions and in the direction the recording can be derived and thus the fastener enables multiple use.

The fastening element can be designed in one or more parts and can be formed, for example, from a metal or plastic material or from a combination of metal parts and plastic parts. In one possible embodiment, the fastening section is made of plastic and the spring element is made of metal. Such a design of the fastening element with a fastening section made of plastic, in which a spring element, for example made of steel, is firmly held, is less susceptible to wear and tear and enables multiple use.

One possible embodiment provides that the spring element comprises a base body from which spring arms protrude radially outward and which engage in the inside of the receptacle in a form-fitting and / or force-fitting manner. Axial forces and their dissipation in both directions can be adjusted in a targeted manner by means of the spring arms.

Another aspect provides that the base body of the spring element is sleeve-shaped and comprises several spring arms along a longitudinal extent of the base body one above the other in at least one row. Such a one-sided or one-row arrangement of spring arms on the base body enables asymmetrical power transmission and dissipation. Alternatively, at least two rows of spring arms can be diametrically opposed to one another with respect to the base body. Such an arrangement of spring arms on the base body, in particular two-sided or two-row, enables symmetrical force transmission and dissipation.

In addition, outside of the row of spring arms, the base body can have a wave-shaped section in some areas. The wave-shaped section enables in particular a frictional or clamping connection with the inside of the receptacle. In a possible embodiment, the spring arms can protrude radially outward and then penetrate into the inside of the receptacle when inserted in the receptacle and enable a form fit and / or force fit with the inside of the receptacle. As an alternative or in addition, the spring arms can project radially inward from the base body and, when the connecting element is inserted, can form a positive and / or non-positive connection with the connecting element.

The spring element can thus be held in the receptacle by frictional or clamping engagement by means of the wave-shaped section of the spring element. Additionally or alternatively, the spring element can be held in the receptacle by positive and / or non-positive locking by means of the spring arms of the spring element which are directed radially outward and protrude from the base body and engage the inside.

Another embodiment provides that adjacent spring arms of the spring element have at least one of the rows alternately radially outwardly and radially inwardly directed spring ends. In particular, the spring ends protrude from the spring element and can thus engage positively and / or non-positively in the respectively adjacent element - the inside of the receptacle or an outside of the connecting element. Such a spring element thus enables a form fit and / or force fit of the spring element with the fastening section of the fastening element for the associated component and a form fit and / or force fit of the spring element with the connection element of the other component.

In addition, the spring arms of one or more rows are arranged at an axial distance from one another. When a connecting element is used, this enables a corresponding non-positive and / or form-fitting connection to the latter, which is axially adjustable, for example can be adjusted in adjustment steps by means of the corresponding distances. This enables axial adjustment steps to compensate for tolerances, in particular small component tolerances, in small steps of, for example, 0.2 cm to 1 cm, in particular 0.35 cm.

In one possible embodiment, the spring arms are designed as locking arms, ratchets or clamping arms.

Another aspect provides that the fastening section has coupling elements in the direction of a head section of the fastening element, on which a sealing element is arranged. The fastening section is designed in particular as a sleeve and forms a socket of the fastening element. The fastening section and the sealing element can be formed as one component, in particular made of plastic. For example, the fastening section and the sealing element are designed as a 2-component plastic injection-molded part. The fastening section is made from a harder plastic material and the sealing element integrated in the fastening section is made from a softer plastic material. The spring element is formed from metal, in particular from a steel material, for example spring steel.

In addition, the fastening section below the coupling elements can have a circumferential edge or a flange for supporting the component. The receptacle of the fastening section is designed to be open at least on one side, in particular on the head side, for receiving a connecting element of the other component. Alternatively, the receptacle can also be designed as a through opening at the bottom end and thus open on both sides. Furthermore, the receptacle on the head-side and / or bottom-side end can have a circumferential and inwardly directed edge, in particular an inner edge. An inwardly directed inner edge into the receptacle additionally secures the arrangement of the spring element in the receptacle axially upwards and / or downwards.

The sealing element also has an outer circumference which is larger than the outer circumference of the fastening section and / or an inner circumference which is smaller than the circumference of the receptacle. This enables a secure and damped arrangement of the connecting element in the fastening element.

The device according to the invention for compensating for tolerances between two components to be connected, wherein a first component is provided to which a second component can be fastened in an axially adjustable manner, and which comprises the fastening element described above, which can be fastened to the first component, one with Second component connected connecting element, such as a connecting bolt or a connecting screw, engages axially adjustable in the receptacle of the fastening element.

The spring element inserted in the receptacle of the socket-shaped fastening element and axially fixed in both directions has the task of connecting the engaging connecting element and the fastening element through shape and form when the connecting element is inserted and thus into the inner spring element until a defined force is reached / or to maintain a positive connection. When the defined force is exceeded, the connection to the engaging connecting element is released so that the connecting element can move, in particular shift, adjust or rotate relative to the fastening element, so that tolerances can be compensated for. The tolerance compensation function can be implemented for smooth connecting elements or for corrugated connecting elements or connecting elements with threaded sections. A corrugated connecting element is used in particular in connection with asymmetrically acting spring elements, for example with higher pull-out, in particular pull-out, forces than insertion, in particular insertion forces. A smooth connecting element is used in particular in connection with symmetrically acting spring elements, which effect a stepless adjustment and thus a stepless tolerance compensation. This enables a high level of adjustment accuracy.
