Definitions
- the invention relates to a steering column arrangement with the features of the preamble of patent claim 1.
- steering columns are designed so that their inclination and length can be changed for comfort purposes. This allows them to be adjusted to the individual needs of a driver.
- Clamping means are provided to fix the steering column in its position.
- Such a steering column is known for example from EP 0 802 104 AI.
- the steering column described in this document has a vehicle-mounted bracket on which clamping means in the form of lamellae are mounted.
- the steering column is connected to the vehicle-fixed console via these clamping means. In an open position of the clamping means, it is possible to move the steering column relative to the console. In a closed position of the clamping means, the steering column is fixed in relation to the console.
- the clamping device must be designed so that it reliably and permanently blocks the changeability of the position of the steering column.
- a steering column that is not adjustable for comfort reasons is disclosed, which is connected to the console via a bracket.
- Bolts are provided which engage in elongated holes drilled in the bracket and, in the event of an accident, enable the bracket to be moved relative to the console while absorbing energy.
- the present invention is therefore based on the object of providing a steering column arrangement in which, while maintaining known comfort functions, the safety of vehicle occupants is increased and reliable use of the steering column arrangement is ensured.
- the solution according to the invention is characterized by a steering column arrangement with a console arranged fixed to the vehicle, and a steering column which, for reasons of comfort, is variable in its inclination and in length.
- clamping means are also provided.
- a console slide is arranged between the console fixed to the vehicle and the steering column with the clamping means, which is connected to the console in such a way that a linear displacement of the console slide along the console is possible.
- an actuating element for releasing and locking the clamping means is provided, which is in operative connection with the clamping means. The operative connection is made detachable.
- the possibility of releasing the connection between the actuating element and the clamping means has the advantage that after. Loosening the connection fixes the position of the clamping means and the actuating element can be moved independently of the clamping means. A loosening of the operative connection between the actuating element and the clamping means causes the position of the clamping means to “freeze” because the clamping means cannot be easily changed without the actuating element. In this way it can be ensured, for example, that the clamping means are not released in certain situations, even though the actuating element is moved. Such a situation can occur, for example, in the event of an accident if an axial force acts on the steering column, which causes the steering column to be displaced. because this would result in an uncontrolled, especially resistance-free movement of the steering column to the front without energy absorption.
- the operative connection between the actuating element and the clamping means is released in the event of the console carriage being displaced relative to the console.
- the console carriage is moved relative to the console with an axially on the steering column. le applied force, such as occurs in an accident. In this situation it is important that the clamping means maintain their locking position. If the operative connection between the actuating element and the clamping means is now released in the event of the console slide being moved relative to the console, it is ensured that the clamping means maintain their locking position and thus the clamping means maintain the once-fixed position of the steering column. This ensures that the steering column performs a controlled movement. The movement takes place only by a relative displacement of the console carriage to the console. All other elements of the steering column arrangement maintain their position. This ensures that the shifting is defined, that is to say in particular via a defined reduction in force.
- the clamping means can be mutually overlapping lamellas which are penetrated by a clamping bolt.
- a defined frictional force can be built up via lamellae, which guarantees a reliable fixing of the steering column arrangement and at the same time ensures that the clamping means can be easily released.
- clamping means can be arranged on the clamping bolt, such as, for example, disks which can be displaced relative to one another and, depending on their position relative to one another, exert pressure on the lamellae via the clamping bolt.
- the actuating element can be a lever, for example.
- the lever can be arranged so that one end points towards the vehicle interior and is therefore easy to handle by a vehicle occupant.
- the other end of the lever can interact with the clamping means.
- the Clamping means transferred from an open position to a closed position or vice versa.
- a positive connection has the advantage that the force required to release the connection can be set precisely. This has the advantage that a defined tear-off force can be set.
- the actuating lever can, for example, have a U-shaped receptacle for a corresponding connecting element of the clamping means.
- the U-shaped receptacle can be designed as a double, for example.
- a double has the advantage that a frictional connection can be established which has an influence on the release behavior, in particular the resistance opposed to the release, of the operative connection between the actuating lever and the clamping means.
- the receptacle is advantageously oriented such that, in the event of the console carriage being displaced relative to the console, the connection between the actuating lever and the clamping means can be released.
- the open end of the U-shaped receptacle can be oriented in the direction in which the console carriage moves relative to the console.
- the lever can have a driver which is oriented such that it moves on the console when the console carriage is moved comes to rest, which prevents further movement of the lever becomes. If the console slide is moved further, the connection between the lever and the clamping device is released.
- FIG. 1 shows a three-dimensional representation of a steering column arrangement according to the invention before an impact
- FIG. 2 shows a three-dimensional representation of the steering column arrangement according to the invention according to FIG. 1 after an impact
- FIG. 3 shows a three-dimensional representation of an actuating lever according to the invention
- Fig. 4 is a three-dimensional representation of the actuating lever according to the invention according to Figure 3 from the opposite side as well
- Fig. 5 is a schematic representation of a further embodiment of an actuating lever according to the invention.
- a steering column arrangement 1 is shown in FIG.
- the steering column arrangement 1 has a console 2 arranged fixed to the vehicle.
- the console 2 has a substantially rectangular cross section. It has receptacles 3 for fasteners, not shown. With these fasteners, the console 2 is mounted on a vehicle, also not shown. Furthermore, the console 2 has an elongated hole 4, which extends over a large part of the length of the Console 2 extends. In slot 4 is a sliding block
- console carriage 5 arranged, on the console 2, a console carriage
- the connection of the console carriage 6 via the sliding block 5 mounted in the elongated hole 4 enables the console carriage 6 to be displaced relative to the console 2 fixed to the vehicle.
- the displacement path is predetermined by the length and orientation of the elongated hole 4.
- the steering column arrangement 1 also has a steering column 7 with a jacket tube 8 and a steering spindle 9 rotatably mounted in the jacket tube 8.
- the steering spindle 9 serves to receive a steering wheel (not shown) and to transmit a rotary movement introduced into the steering wheel by a driver to a steering gear.
- the console slide 6 On its side facing away from the console 2, the console slide 6 has two cheeks 11 and 11 ′′, between which the jacket tube 8 is arranged.
- both the cheeks 11 ⁇ and 11 ′′ and the jacket tube 8 are penetrated by a clamping bolt 12.
- the lamella package is 13 ⁇ via bolts 14 to the wall 11 ", respectively.
- the plate pack 13 ′′ is in turn connected to the casing tube 8 via bolts 15.
- the clamping means 16 are composed of two relatively slidable discs 16 and ⁇ 16 "(see Figure 2). By means of balls arranged between the disks and running in slide tracks introduced into disks 16 ⁇ and 16 ⁇ , the distance between the disks changes as soon as they are moved relative to one another. The movement of the discs 16 ⁇ and 16 "to each other takes place as Rotational movement that the disk 16 "executes relative to the disk 16 ⁇ around the clamping bolt.
- the clamping means either assume an open position in which the steering column 7 can be moved and pivoted is, or a closed position in which the position of the steering column 7 is fixed. If the distance between the disks 16 ⁇ and 16 ⁇ is minimal, the open position is present; if the distance between the washers 16 ⁇ and 16 ⁇ is maximum, the closed position is present.
- a lever 17 is provided so that a vehicle occupant can easily actuate the clamping means.
- One end of the lever 17 is operatively connected to the clamping means 16 ⁇ and 16 ", while the other end of the lever 17 protrudes into the vehicle interior so that it can be operated easily.
- the lever 17 is now closer in connection with FIGS. 3 and 4 explained.
- the lever 17 has an elongated substantially rectangular shape. Recesses 18 and 19 are provided at both ends.
- the lever 17 has a step 21 in its central region. The step 21 serves to guide the lever 17 around the casing tube 8 in its installed position.
- a U-shaped receptacle 22 is provided in the area of the upper recess 18.
- the receptacle is characterized by a web 23 with an undercut extending around the recess 18. The undercut creates a guide groove 24 which is delimited on one side by the web 23 and on the other side by the lever 17.
- the design of the receptacle 22 just described creates the possibility of a form-fitting receptacle of a connecting element which has a degree of freedom with respect to the lever 17 the receptacle 22 allows the lever 17 to be displaced in the direction of the arrow A.
- the recess 19 serves to receive connecting means which are not of interest in connection with the invention and is therefore not to be described further here.
- a nose 25 is arranged pointing in the direction of arrow A.
- the nose 25 has a recess 26.
- the recess 26 serves to receive a needle, not shown, which connects the lever
- FIG. 4 shows the back of the lever 17 shown in FIG. 3. It is the recesses
- the nose 25 is shown with the recess 26 and the notches 27.
- a projection 28 is provided which has ribs 29 for stabilization.
- the ribs 29 are arranged on the side of the projection 28 opposite the recess 18.
- An abutment connection between the lever 17 and the console 2 can be established via the projection 28.
- the operation of the projection 18 is also explained in more detail below.
- the steering column 7 of the steering column arrangement 1 can be changed both in its inclination and in its length.
- the lever 17 must be at its bottom pointing end are actuated, that is to say shifted in the direction of arrow B according to FIG.
- the displacement causes the lever 17 to pivot. Since the lever 17 is connected via its receptacle 22 to a corresponding connecting element 31 (see FIG. 2) of the disk 16 "of the clamping means 16, the displacement of the lever 17 causes the disk 16" to rotate relatively to the disk 16 ⁇ .
- the distance between the two discs changes - the discs 16 ⁇ and 16" slide closer to each other.
- the console carriage 6 detaches from the console 2 and the steering column 7 can be moved relative to the console 2.
- the projection 28 establishes a connection between the lever 17 and the console 2.
- the console 2 prevents further displacement of the lever 17.
- the lever 17 is thus fixed relative to the console 2 via the projection 18. If the force acting axially on the steering column 7 now exceeds a certain amount, this leads to the operative connection between the lever 17 and the clamping means 16 being released.
- tel 16 which are firmly connected to the advancing steering column 7 via the clamping bolt 12 are pushed out of the receptacle 22 of the lever. So that the pushing out does not take place at the smallest force applied to the steering column 7, but only from a predetermined force, a connection is established between the lever 17 and the tensioning means 16 via the nose 25 and the needle mounted therein Notches 27 are designed so that they release the needle from a certain force. This means that it is only possible to release the clamping means 16 from the receptacle 22 once this predetermined force has been exceeded.
- clamping bolt 12 only extends as far as the clamping means 16 and no longer through the lever 17. This feature enables the operative connection to be released due to a translational displacement of the steering column arrangement 7 relative to the console 2.
- FIG. 5 A further embodiment of an actuating lever 17 according to the invention is now described below (see FIG. 5).
- one end of the lever 17 is operatively connected to the tensioning means 16 while the other end of the lever 17 projects into the vehicle interior.
- the operative connection between the lever 17 and the clamping means 16 is established by the lever 17 having a round recess 31, in which a likewise shaped projection 32 of the clamping means 16 is arranged.
- the size of the round recess 31 and the molding 32 are coordinated with one another in such a way that they can move relative to one another - the lever 17 can be rotated about the clamping means 16 without the clamping means also moving.
- a fixie tion of the two components for establishing the operative connection takes place via a split pin or a wire 33 which is arranged in a bore 34 extending through the lever 17 and the molded part 32 of the clamping means 16.
- This fixation means that when the lever 17 is actuated, the clamping means 16 are also moved, which leads to the opening and closing of the clamping means 16 and the previously described options with regard to the comfort adjustment of the steering column.
- the cotter pin or wire 33 is connected to the console 2 via schematically illustrated connection means 35.
- the connecting means 35 can be, for example, the continuation of the wire 33.
- the console carriage 6 is released from the console 2, as already described, and displacement of the steering column 7 relative to the console 2 becomes possible.
- the split pin or wire 33 is connected to the console 2. If the steering column 7, on which the clamping means 16 are arranged, moves relative to the console 2, the lever 17 is also moved in this exemplary embodiment. The cotter pin or wire 33 remains however. Due to this relative movement, the wire 33 is released from the bore 34 and thus releases the movement between the lever 17 and the clamping means 16. As a result, no matter how the lever 17 moves relative to the clamping means 16, the clamping remains closed. This reliably prevents the risk of uncontrolled opening of the clamp when the steering column 7 is displaced in the event of an accident.
