    Cab mounting for a tiltable cab of a commercial vehicle Description
    The invention relates to a cab suspension for a tiltable cab of a commercial vehicle, in particular a front cab suspension for a tiltable cab of a truck.
    From EP 1 690 781 A2 a front cab mounting for a tiltable cab of a commercial vehicle is already known. Such cab mountings usually include a swing construction for damping movements of the cab during a ride of the utility vehicle and a torsion bar construction for manually operated tilting of the cab. A disadvantage of such cab bearings is that the swing function and the torsion bar function influence each other, in particular with respect to their bearings. Another disadvantage is that in a front crash case, the engine of the commercial vehicle tends to penetrate into the cab floor.
    An object of the invention is to provide an improved and / or alternative cab suspension for a tiltable cab.
    This object can be achieved with the features of the independent claim. Advantageous developments of the invention can be taken from the subclaims and the following description of preferred embodiments of the invention.
    The invention provides a preferably front cab suspension for a tiltable cab of a commercial vehicle, for. B. a truck. The cab is conveniently tilted by hand.
    The cab mounting has two brackets for frame-mounted, in particular cross-beam-resistant mounting on the frame structure of the commercial vehicle. The frame construction expediently comprises at least one cross member and two side members.
    The cab suspension further comprises a swing construction for damping movements of the cab during a drive of the utility vehicle and a torsion bar construction for tilting the cab, in particular by manual force.
    The swing construction may preferably have two lateral, e.g. B. bearing block-shaped bearing sections and a connecting the bearing sections cross member, z. B. a hollow profile element having.
    The torsion bar construction is preferably designed substantially U-shaped, which z. B. by a one-piece substantially U-shaped torsion bar structure or z. B. can be realized by two substantially L-shaped torsion bar structures.
    The cab suspension is characterized in particular by the fact that the brackets have a ramp structure, along which in a front crash case (eg frontal impact) the swing construction can be expediently guided to the rear and / or above, so that expediently the risk of Penetration of a commercial vehicle engine in the cab floor prevented or at least reduced.
    Alternatively or additionally, the cab suspension is characterized in particular by the fact that the swing construction and the torsion bar construction are functionally separated from each other.
    It is possible that the swing construction and the torsion bar construction are supported by means of separate bearings and / or are separated by means of execution as separate component units from each other to allow functional separation functional.
    It is possible that the torsion bar construction z. B. is rotatably mounted on the brackets, so that the brackets serve as storage for the torsion bar construction.
    The consoles can each with z. B. a biasing means for biasing the torsion bar construction may be provided.
    The bearing sections of the swing construction, in particular at the front, z. B. be supported by means of deformation bearings, so that the deformation bearings serve as storage for the swing construction. The deformation bearing can be suitably designed as strut, elastomer, pot and / or Punktkipplager.
    The bearing sections can rear z. B. be stored on side rails of the frame structure of the commercial vehicle, for. B. rest.
    In particular, the deformation bearings do not serve for supporting the torsion bar construction, so that preferably the deformation bearings of loads of the torsion bar construction are at least substantially insulated.
    The deformation bearing z. B. be passed through through holes in the consoles and / or z. B. be supported directly with their underside under the consoles. The passage openings are preferably formed in useful substantially horizontal sections of the consoles.
    It is possible that in a front-crash case, the deformation bearings are moved out of the passage openings in the consoles (pulled out), expedient substantially upwards.
    The cab bearing can have two bearing blocks for rotatable mounting of the cab. The bearing blocks can z. B. rotatably mounted on the bearing portions of the swing structure, so that they z. B. are rotatable relative to the bearing portions of the swing structure.
    The bearing sections of the swing construction expediently each comprise two essentially projecting mounting sections.
    The bearing blocks for rotatable mounting of the cab can preferably be rotatably mounted on and / or between the two mounting portions.
    It is possible that the torsion bar construction is rotatable about at least a first axis, the bearing sections of the swing structure are rotatable about a second axis of rotation and / or the two bearing blocks for rotatably mounting the cab are rotatable about a third axis of rotation.
    The at least one first axis of rotation, the second axis of rotation and / or the third axis of rotation are preferably spaced apart from one another and / or run essentially parallel to one another.
    It is possible that in the front crash case in particular the transverse element of the swing structure along the ramp structure is expediently feasible upwards and / or to the rear. Consequently, in the front-crash case, in particular, the transverse element of the swing construction abuts against the ramp structure.
    The consoles can z. B. each having an upwardly projecting portion and preferably a substantially horizontal portion.
    The ramp structure can, for. B. are formed by end faces of the upwardly projecting portions, the two bearing portions of the swing construction, z. B. each side are arranged outside the two upwardly projecting sections and / or the two bearing blocks can, for. B. are each arranged laterally outside of the two upwardly projecting sections.
    It is possible that the consoles are mounted on a cross member of the frame structure. Alternatively or additionally, the deformation bearings may be mounted on formed on the cross member bearing structures, for. As retaining flanges, retaining brackets, retaining projections, Halteeinbuchtungen etc., which may preferably be formed under the brackets. The storage structures can, for. B. protrude from the cross member or be integrated therein.
    From Figures 4 to 6 results in particular that the cab is appropriate in tilt position and driving condition on the cab support placed, which is particularly feasible that the torsion bar construction, in particular their two stabilizers, by the biasing device to stop (tilting position) upwards are rotatable or only after putting on the cab in level position are prestressed.
    The bearing sections of the swing construction and / or the bearing blocks for mounting the cab may preferably comprise supporting structures extending substantially in the longitudinal direction of the utility vehicle.
    It should be mentioned once again that the torsion bar construction can expediently be embodied in one piece or in two parts by means of two substantially L-shaped torsion bar structures in a substantially U-shaped manner.
    It should also be mentioned that by means of the cab bearing preferably multi-axial loads on the deformation bearings can be prevented.
    It should also be mentioned that the torsion bar construction can be made of preferably one or more bar profiles, in particular hollow or. The latter applies expediently also for the transverse element of the swing construction.
    The invention includes not only a cab suspension as described herein, but also a cab provided with such cab suspension for a commercial vehicle, especially a truck.
    The preferred embodiments and features of the invention described above can be combined with one another. Other advantageous developments of the invention are disclosed in the dependent claims or will become apparent from the following description of preferred embodiments of the invention in conjunction with the accompanying drawings.

    Embodiment of the invention,
    FIG. 2 shows a front view of the cab mounting of FIG. 1,
    FIG. 3 shows a sectional view along section A-A of FIG. 2,
    FIGS. 4 to 6 illustrate a process for placing the swing structure to the torsion bar construction, particularly deformation bearings, according to an embodiment of the invention; and FIGS
    Figure 7 shows a side view of a cab according to an embodiment of the invention.
    FIG. 1 shows a perspective view of a cab mount 1 for a driver's cab 10 which can be tilted by hand power (see FIG. 7) of a commercial vehicle, in particular a truck.
    The cab mount 1 is designed in particular as a front cab suspension.
    The cab mount 1 comprises two brackets 2a and 2a for frame-fixed mounting to a frame structure having at least one cross member and two side members, in particular chassis construction of the commercial vehicle. The brackets 2a, 2b are used in particular for mounting on a cross member of the frame structure.
    A swing construction 3 serves to dampen movements of the driver's cab 10 (eg pitching, yawing and / or rolling movements) during a drive of the utility vehicle. The swing construction 3 comprises two lateral, z. B. bearing block-shaped bearing portions 3a and 3b and the two bearing portions 3a, 3b connecting cross member 3c, z. B. a round tube. The bearing sections 3a, 3b comprise supporting structures in the longitudinal direction of the utility vehicle.
    A torsion bar construction 4 is used to tilt the cab 10 by hand. In Figure 1, the torsion bar construction 4 is made up of two substantially L-shaped torsion bar structures forming a substantially U-shape. However, it is within the scope of the invention also possible to use a one-piece, preferably also substantially U-shaped torsion bar construction instead of the twofold in Figure 1 torsion bar construction. The torsion bar construction 4 is rotatably mounted on the brackets 2a, 2b, so that the brackets 2a, 2b serve as a bearing for the torsion bar construction 4. The brackets 2a, 2b each include a biasing device 7 (eg, Figure 4) for biasing the torsion bar structure 4, which allows the tilting of the cab 10 with manual force or at least supportive acts for this purpose.
    The brackets 2a, 2b have a ramp structure Ra and Rb. In a front crash case of the commercial vehicle, the swing structure 3, in particular by means of the cross member 3 c, along the ramp structure Ra, Rb are expediently pushed backwards and upwards, whereby the risk of penetration of the commercial vehicle engine in the cab floor can be reduced or even completely avoided ,
    The bearing sections 3 a, 3 b of the swing structure 3 are expedient front by means of z. B. designed as an elastomeric / pot bearing bearing bearings 5a and 5b, wherein the deformation bearings 5a, 5b but can also be designed as a suspension strut bearing. The deformation bearings 5a, 5b thus serve as bearings for the swing construction 3.
    The torsion bar construction 4, however, is not supported by means of the deformation bearings 5a, 5b, but by means of the brackets 2a, 2b. As a result, it can be ensured that the deformation bearings 5b, 5b are substantially insulated from loads of the torsion bar construction 4, so that the deformation bearings 5a, 5b are expediently acted upon at least almost exclusively by substantially vertical loads from the swing construction 3 and thus preferably an undesired multi-axial load the same can be at least substantially avoided.
    The brackets 2a, 2b preferably each comprise a substantially horizontal section and in each case an upwardly projecting section 2.1 and 2.2 (see Figure 2).
    The deformation bearings 5a, 5b are guided in particular through through openings in the brackets 2a, 2b, in particular through the essentially horizontal sections of the brackets 2a, 2b, from which they are expediently expelled in the frontal crash case.
    The cab mount 1 further comprises two bearing blocks 6a and 6b, which are for rotatably mounting the cab 1 and are rotatably mounted to the bearing portions 3a, 3b of the swing structure 3, so that the two bearing blocks 6a, 6b relative to the bearing portions 3a, 3b the swing structure 3 are rotatable.
    The bearing sections 3a, 3b of the swing construction 3 each comprise two upwardly projecting mounting sections 3.1 and 3.2 on the one hand and 3.3 and 3.4 on the other hand.
    The bearing blocks 6a, 6b are rotatably mounted on and / or between the two mounting sections 3.1, 3.2 and 3.3, 3.4.
    The bearing sections 3a, 3b of the swing construction 3 and the bearing blocks 6a, 6b comprise support structures extending substantially in the longitudinal direction of the utility vehicle.
    The rear torsion bar structure in FIG. 1 and the torsion bar structure of the torsion bar structure 4 in front of FIG. 1 are rotatable about two essentially parallel axes of rotation, which are provided together with the reference number D1. In a one-piece embodiment of the torsion bar construction 4, only one axis of rotation D1 would expediently be present.
    The bearing portions 3a, 3b of the swing structure 3 are rotatable about a rotation axis D2.
    The two bearing blocks 6A, 6B are rotatable about a rotation axis D3.
    The axes of rotation D1, the axis of rotation D2 and the axis of rotation D3 are expediently spaced apart from one another and run essentially parallel to one another.
    The swing construction 3 and the torsion bar construction 4 are functionally separated from each other. Thus, in particular, the swing construction 3 and the torsion bar construction 4 are designed as separate, separate component units and additionally supported on separate bearings (2a, 2b, 5a, 5b).
    FIG. 2 shows a front view of the cab mount 1 of FIG. 1.
    It can be seen in particular from FIG. 2 that the bracket 2 a comprises the upwardly projecting part section 2. 1 with the ramp structure R a and the bracket 2 b comprises the upwardly projecting part section 2. 2 with the ramp structure 2 b.
    The two bearing sections 3a, 3b of the swing construction 3 as well as the two bearing blocks 6b, 6b are expediently arranged laterally outside the two sections 2.1, 2.2.
    The brackets 2a, 2b are suitably provided to be mounted with their lower sides on a cross member of the frame structure (not shown). The deformation bearings 5b, 5b are provided to suitably be supported on bearing structures (not shown) formed on the cross member, e.g. B. supported by the cross member retaining projections.
    FIG. 3 shows a side view of the cab mount 1 according to section A-A of FIG. 2.
    Figures 4 to 6 illustrate a process for placing the swing structure 3 on the torsion bar structure 4, in particular on the deformation bearings 5a, 5b according to an embodiment of the invention.
    Figures 4 to 6 also show the provided on the bracket 2a biasing means 7 for biasing the torsion bar construction 4, which can be realized in an appropriate manner identical to the console 2b.
    From FIGS. 4 to 6, it can be seen that the driver's cab 10 can be placed on the cab suspension 1 in the tilted position and in the driving state, which can be realized in particular in that the two stabilizers 4 (torsion bar construction) move upwards by the pretensioning device 7 to stop (tilting position) be rotated or biased only after putting the cab 10 in level position.
    FIG. 7 shows a side view of a driver's cab 10 with a cab suspension 1 as described herein and a load and moment load occurring in a front crash case of the commercial vehicle.
    The invention is not limited to the preferred embodiments described above. Rather, a variety of variants and modifications is possible, which also make use of the inventive idea and therefore fall within the scope. Moreover, the invention also claims protection of the subject matter and the features of the subclaims independently of the features and claims referred to.
