    Title Field of the invention The present invention relates to a suspension system for a sound damping device in a vehicle and a vehicle comprising such a suspension system according to the preambles of the independent claims.
    Background of the invention In a vehicle, a sound damping device is arranged in connection with the exhaust pipe to steam the sound from the engine. Such a sound evaporation device may, for example, also comprise a particle filter for exhaust gas aftertreatment. Today, the sound-damping device is usually mounted on a vehicle without the requirement that it can then be easily dismantled.
    However, the particle filter in the sound damping device may need to be replaced and thus the sound damping device also needs to be dismantled. This disassembly can be extremely difficult because the sound damping device can weigh between 100 and 150 kg. The sound damping device on a bus can be fixed on the side of the rear of the bus.
    In addition, there are high demands on the evaporation of vibrations to give the passengers in the bus a high level of comfort.
    The invention has identified a problem with the present suspension system, among other things regarding the responsibility to disassemble the sound damping device.
    The object of the present invention is thus to provide a suspension system for a sound damping device which ensures that the sound damping device is easy to assemble / disassemble and that this can be done in a safe manner. In addition, it must meet the requirements for evaporation.
    SUMMARY OF THE INVENTION The above objects are achieved by the invention defined by the independent claims.
    Preferred embodiments are defined by the dependent claims.
    According to a first aspect, the invention relates to a suspension system for a sound damping device in a vehicle. The system comprises at least two mounting parts arranged in connection with the underside of the sound-damping device and at least two slide rails, with a first and a second spirit, which rails are intended to be arranged in connection with the underside of the sound-damping device. In addition, the system comprises at least two support rails, with a first and a second spirit, which rails are intended to be fixedly arranged at the vehicle. The sound damping device is fixedly arranged at the slide rails via at least two steaming units intended to be mounted in said mounting parts. Furthermore, the slide rails are intended to be arranged in connection with and to be movable in relation to the support rails, which makes it possible for the sound damping device to be extendable.
    The suspension system aims for the sound damping device to be exposed for, for example, 20 service garages. The system is also space-efficient and easy to assemble and disassemble. In addition, assembly / disassembly can be done in a safe way.
    According to a second aspect, the invention relates to a vehicle comprising a suspension system.

    Detailed Description of Preferred Embodiments of the Invention Figure 1 shows a perspective view of a suspension system for a sound damping device 1 at a vehicle. The suspension system comprises at least two mounting parts 13 arranged in connection with the underside of the courier steaming device. At least two mounting openings 15 are arranged in each mounting part. In addition, the suspension system comprises at least two slide rails 2 and at least two support rails 3. The slide rails 2 are intended to be fixedly arranged at the underside of the skin steaming device via steaming units 4 mounted in the openings 15 in the mounting parts. The slide rails 2 are also intended to be arranged in connection with and be movable in relation to the support rails 3, which makes it possible that the sound damping device is also movable and can be pulled out from the team when it is mounted in the vehicle. The support rails 3 are intended to be arranged parallel and horizontally fixed to the vehicle. Since the slide rails 2 are arranged in connection with the support rails 3, this means that the alien slide rails will be substantially parallel and horizontally arranged in connection with the support rails 3.
    As can be seen from Figure 3, which shows a perspective view of a suspension system when the sound damping device is in a retracted mounted position, the support rails 3 are arranged in connection with a support structure 11, 12. The support structure is intended to be arranged in connection with the vehicle chassis and / or body. For example, the lower part of the standing frame 11 may be fixed in the chassis of the vehicle and the upper part of the standing frame 12 may be fixed in the body of the vehicle. The post structure 11, 12 comprises beams which are substantially angular at right angles to sliding and support rails 2, 3.
    Figure 2 shows a perspective view of the slide rail 2 and the support rail 3. The slide rail 2 is intended to be arranged in connection with the inside of the support rail 3. In this embodiment, both rails are substantially U-shaped. In an alternative embodiment, the slide rail does not have to be U-shaped, but can only consist of a flat rail which abuts the inside of the support rail 3 (the middle part of the U). Two mounting openings 25 are arranged in connection with the slide rail 2. In these mounting openings the steaming units 4 are intended to be mounted. The mounting openings 25 can be arranged in a first and a second mounting post 23, 24. These mounting posts are also shown in Figure 5, which is a side view of a slide rail and a support rail in the extended layer. Both the stand rail 3 and the slide rail 2 are longitudinal narrow elements with a first and a second spirit.
    In figure 5, the slide rail 2 is extended about 550 mm in relation to the support rail 3. The slide rail is extendable between 500 and 600 mm in relation to the support rail.
    The slide rail 2 preferably comprises at least two rollers 22 arranged at its first spirit, which can be seen in figure 2. The rollers can be connected by means of a shaft 21. The sound damping device 1 is mounted in the vehicle, i.e. When the slide rail 2 is completely inserted into the support rail 3, the rollers 22 are countersunk in the respective recesses 33 (only one recess is shown in figure 2) in the support rail 3. The inserted layer is shown in figure 3. The slide rail 2 is fixedly connected to the support rail 3 by means of a fixed device dA sound damping device 1 is mounted in the vehicle. Thus, the sound damping device is mounted on a safe salt. The fastening device can be, for example, screws, nuts, rivets or the like.
    The DA slide rail 2 is movable in relation to the support rail 3, i.e. dA the slide rail is pulled out or pushed in, the rollers rest against the longitudinal sides of the support rail 3 and contribute to the muffler being easy to disassemble / assemble. The extended layer can be seen, for example, in Figures 4 and 5.
    When the slide rail 2 is fully extended, the fixedly connected mcd support rail 3 is partly a fixed device. Thus, the sound damping device is securely arranged in the extended layer, whereby service guards can be made. The fastening device can be, for example, screws, nuts, rivets or the like.
    When the sound damping device has been extended and pushed into the vehicle, the movement of the slide rail 2 in relation to the support rail 3 is limited by a ratchet rod 31 arranged at the first end of the support rail 3. The spar rod 31 then comes into abutment against the first end of the slide rail 2.
    When the sound damping device is pulled out, the movement of the slide rail 2 is limited in relation to the support rail 3 by a spar device 32. The spar device comprises projecting flanges arranged at the longitudinal sides of the stud rail 3. The flanges are arranged substantially perpendicular to the inside of the support rail. When the sound damping device is fully extended, the ratchet device 32 comes into abutment against the rollers 22 of the slide rail. Both ratchet rod 31 and ratchet device 32 can be seen in figure 2.
    The location of the steam units 4 is shown in Figures 1, 3 and 4. However, their design is most clearly seen in the perspective view in Figure 6. The steam units comprise an upper and a lower cylindrical steam pad 41, 42 and an intermediate part 44. The pads 41, 42 and the intermediate part 44 is connected by a rod 43 which is intended to be arranged with a longitudinal central axis C.
    The steam 43 of each steaming unit is intended to be mounted in said mounting openings on the slide rails 2 and in openings 15 in the mounting parts 13. The mounting parts have projecting right-angled flanges. When the sound damping device is fixedly arranged at the slide rail, the surface of the mounting part 13 in which the openings 15 are arranged and the surfaces of the mounting post 23, 24 in which the openings 25 are arranged will be arranged in parallel in relation to each other. These surfaces are slightly inclined, so that the normal to them will have a certain slope in relation to a vertical line. The normal to the surface of the mounting part 13 and to the surface of the mounting post 23, 24 is parallel to the longitudinal central axis C of the rod. The longitudinal central axis C of the rod 43 has an inclination a relative to a vertical reference line V. The inclination a is about 0.
    The steam pads 41, 42 of the steam units 4 are homogeneous cylinders made of an elastic material. This elastic material may comprise metal rivets, rubber or plastic or other hot metal material.
    When the sound damping device is to be pulled out, the fastening device arranged in slide rails and support rails is unscrewed. Then the sound damping device 1 together with the parts attached thereto (slide rails and steaming units) can be pulled out. The sound damping device is mainly square and each side amounts to about 700 mm. The total length of the rails is about 1200 mm. The spar device 32 is arranged at a distance from the first end of the support rail 3 which amounts to between 500 and 600 mm, preferably 550 mm. This corresponds to the distance that the sound damping device can be pulled out as far as possible. The sound damping device is then not completely outside the vehicle, as it is not necessary to carry out service guards. Since the weight of the sound damping device amounts to between 100 and 150 kg, it is desirable not to pull the rails out too far, but instead the rails overlap each other by about 500 mm in the extended layer.
    The lamps in the suspension system for the sound damping device are arranged at a height of about 1 m. This allows a relatively good ergonomic position for the person or persons who are to carry out service guards on the sound damping device, or mount / dismount it.
    In a preferred embodiment, the suspension system comprises four mounting openings 15 in the mounting unit 13 arranged in connection with the underside of the sound damping device and four steaming units 4 intended to be mounted in said mounting openings 15 and 25.
    When mounting the sound damping device at the vehicle, the steaming units 4 are arranged in the mounting openings 15 in the mounting parts 13, to then arrange the steaming units 4 also in the mounting openings 25 in the mounting post 23, 24. The steaming units must then be fixed to both mounting parts 13 (on the sound steaming device 23) and to 24 (on slide rail). The slide rails 2 then come into abutment against the support rails 3, so that the rails are completely inserted into each other and the rollers 22 on the slide rails 2 will be located in the recesses 33 on the support rails 3. The slide rails 2 are then attached to the support rails 3 by means of the fastening device. securely mounted in the vehicle.
    The present suspension system is not limited to being used to hang a sound damping device, but can be used for hanging a motor, gearbox or the like.
    The present invention is not limited to the preferred embodiments described above. Various alternatives, modifications and equivalents may be employed. The above embodiments are not to be construed as limiting the scope of the invention, which is defined by the appended claims.
