Description

Description
Elastic mount, in particular rubber-metal mount The invention relates to an elastic mount, in particular a rubber-metal mount, for vibratory decoupling of a part to be mounted on a mobile machine, wherein a component of the part to be mounted or of the mobile machine can be fastened to the elastic mount by means of a screwed connection.
Elastic mounts are used for vibration-free elastic mounting and structure-borne noise and vibration damping of parts on vehicle bodies and employed for example for mounting and fastening of driving motors or driving cabs or driver work stations on vehicle frames of mobile machines. Here, the elastic mount can be formed by a decoupling element, a spring-damper element or a rubber-metal mount. Here, the elastic mount serves to decouple the part to be mounted in order to reduce the transmission of noise and/or vibration between the parts.
Elastic mounts have to be fastened appropriately for fitment, and as a rule a component of the part to be mounted or a component of the vehicle frame is screwed to the elastic mount by means of a screwed connection in the form of a fastening screw which is screwed into a threaded bore of the elastic mount, and a corresponding fastening torque is applied to the elastic mount through the fastening screw. However, during this fitting operation, twisting and distortion of the elastic mount can occur. The distortion resulting from the twisting during fitment can lead to premature damage to the elastic mount, which reduces the service life and can lead to premature failure of the elastic mount. Causes of twisting of the elastic mount during fitment can be an inability to hold the elastic mount while tightening the screw or unfavourable frictional conditions between the mount and the component to be mounted and between the threaded bore of the elastic mount and the fastening screw. If for example the friction in the threaded bore of the elastic mount is high, severe distortion of the elastic mount occurs during fitment. These effects occur in particular with an elastic mount in the form of a rubber-metal mount with an elastic rubber element when the rubber element is twisted due to the fastening torque applied during fitment.
To avoid twisting of the elastic mount during fitment, a positive form-locking connection can be produced between the mount and the component of the part to be mounted or the component of the vehicle body. For example, centering pins can be located between the elastic mount and the component to obtain a positive form-locking and thus twist-free connection and avoid twisting of the rubber element of the elastic mount. However, this requires precise positioning between the component and the elastic mount in order to produce the positive form-locking connection so that equalisation of tolerances is no longer possible, for example by providing the component with a slot receiving the fastening screw or with a bore of enlarged diameter receiving the fastening screw.
The underlying object of the present invention is to provide an elastic mount of the kind named initially with which twisting of the elastic mount can be eftectively avoided during fitment and a long service life can be obtained from the elastic mount.
According to the invention, this object is achieved in that the screwed connection is provided with a torque-transmitting part, and when the elastic mount is fitted to the component, a fastening torque applied to the screwed connection can be supported through the torque-transmitting part on the component. Thus, the idea according to the invention is that the fastening torque applied to the screwed connection when the elastic mount is fitted to the component through the screwed connection is supported through the torque-transmitting part of the screwed connection directly on the component. This makes it possible to avoid the elastic mount being twisted or distorted by the applied fastening torque during fitment so that torsion-free fitment of the elastic mount to the component is obtained. The avoidance of distortions at the elastic mount means that premature damage can be effectively avoided through the torsion-free fitment of the elastic mount so that the elastic mount exhibits a long service life.
According to one preferred form of embodiment of the invention, the component is provided with a receiving opening for receiving the torque-transmitting part, the receiving opening in the component being of such a size that the torque-transmitting part is located with play in the receiving opening and when a fastening torque is applied to the screwed connection by turning the torque-transmitting part in the receiving opening, support for the torque-transmitting part can be obtained in the receiving opening. One essential aspect of the invention is that the receiving opening is larger in size than the torque-transmitting part so that the play produced by this between the receiving opening and the torque-transmitting part allows an equalisation of tolerances which permits simple fitment and easy assembly of the component and the mount. When the component is fitted to the elastic mount by means of the screwed connection, a fastening torque is applied to the screwed connection with the result that the screwed connection turns in relation to the elastic mount and thus the torque-transmithng part turns in relation to the receiving opening in the component and in turn the torque-transmitting part comes into contact with the receiving opening and bears against the latter in order to support the fastening torque between the torque-transmitting part and the receiving opening directly in the component.
This makes it possible to avoid twisting or distortion of the elastic mount occurring when the elastic mount is fitted to the component and thus torsional stress-free fitting of the elastic mount is obtained with a simultaneous equalisation of tolerances between the parts.
Particular advantages are obtained if according to a further development of the invention the torque-transmitting part is formed by a torque-transmitting shaped part arranged on or integral with a fastening pin, and the torque-transmitting shaped part is arranged between a first fastening portion of the fastening pin with which the fastening pin can be fastened to the elastic mount, and a second fastening portion of the fastening pin with which the component can be fastened to the fastening pin. The screwed connection with which the component is fastened to the elastic mount can be formed simply by a fastening pin which can be fastened to the elastic mount by a first fastening portion and holds the component by the second fastening portion. The torque-transmitting shaped part provided to support the fastening torque applied to the fastening pin when the component is fitted to the mount can easily be formed on or integral with the fastening pin.
Expediently, the thickness of the torque-transmitting shaped part is less than the thickness of the material of the component. This ensures in a simple manner that the fastening pin can turn with the torque-transmitting shaped part in the receiving opening when the fastening torque is applied in order to ensure that the torque-transmitting shaped part makes contact in the receiving opening and thus the fastening torque is supported in the receiving opening of the component.
Expediently, the first fastening portion and the second fastening portion of the fastening pin are in each case formed as a threaded portion. Threaded portions of this kind on the fastening pin make it simple to fasten the fastening pin to the elastic mount and to fasten the component to the fastening pin and thus to the elastic mount.
According to one preferred form of embodiment of the invention, the elastic mount is provided with a fastening threaded bush in which the fastening pin can be screwed by the first fastening portion. When the fastening portion is screwed into the elastic mount it is simple to fasten the fastening pin to the elastic mount.
According to an alternative form of embodiment of the invention, the elastic mount is provided with a fastening bush which is provided with a through bore for receiving the first fastening portion of the fastening pin, and the first fastening portion can be fastened to the elastic mount by means of a fastening device, in particular a nut. With a fastening device on the opposite side to the component the fastening pin, which extends through a through bore in a the fastening bush, can also be simply screw-fastened to the elastic mount.
Particular advantages are obtained when the component can be fastened on the second fastening portion by means of a fastening device, in particular a nut. This allows simple screw-fastening and fitment of the component to the elastic mount.
According to one advantageous form of embodiment of the invention, the screw-fastening to the elastic mount can be fastened and arranged pivotably in such a way during fitment of the component that when the fastening torque is applied to the screw fastening, the screw fastening is allowed to turn with the torque-transmitting part on the elastic mount in order to obtain support for the torque-transmitting part in the receiving opening of the component. When the screw-fitting takes the form of a fastening pin which is fastened and arranged in the elastic mount by the first fastening portion, the first fastening portion is thus loosely screwed into the elastic mount or held rotatably in the elastic mount in order to allow rotation of the fastening pin with the torque-transmitting shaped part in relation to the receiving opening and to ensure the torque-transmitting shaped part is supported in the receiving opening when the fastening torque is applied during fitment of the component and thus during tightening of the screw fitting on the fastening pin. With a fastening pin screwed into the elastic mount, such foose fastening can be obtained easily if the fastening pin is not screwed into the fastening bush as far as a stop by the first fastening portion.
The torque-transmitting shaped part can be formed by a transverse pin arranged on the fastening pin. Morever, the torque-transmitting shaped part can be formed directly on the fastening pin in one piece. The torque-transmitting shaped part can exhibit a suitably freely optional geometry with which contact can be obtained in the receiving opening to support the fastening torque. Advantages arise as regards simple manufacture of the torque-transmitting shaped part on the fastening pin if the torque-transmitting shaped part is formed by a square or a rectangular or a polygonal profile section.
The receiving opening in the component can exhibit a shape adapted to the geometry of the torque-transmitting shaped part in order to obtain play and thus equalisation of tolerances and to support the fastening torque by contact and bearing of the torque-transmitting shaped part in the receiving opening. Preferably, the receiving opening is formed by a square or rectangular profile section or a polygonal profile section or a slot.
Particular advantages are obtained with a mobile machine, in particular an industrial truck, with an elastic mount according to the invention for mounting a driving motor, in particular an internal combustion engine or an electric driving motor, which is connected with a gearbox and a steerable driving wheel to form a unit, and/or a driving cab or a driver work station on a vehicle frame. The mount according to the invention, which allows stress-free fitting and at the same time equalisation of tolerances when the parts are fitted, permits simple decoupling of a driving motor and/or a driver work station in the form of a driving cab for example from a vehicle frame of a mobile machine to avoid transmission of noise and vibration, while ensuring the elastic mount has a long service life.
Further advantages and details of the invention are explained in greater detail with reference to the embodiment examples illustrated in the diagrammatic figures in which figure 1 shows an elastic mount according to the invention in a cross-sectional view, figures 2a, 2b show plan views of the elastic mount in figure 1 in the area of the torque-transmitting part in different fitting steps, figure 3 shows a second form of embodiment of an elastic mount according to the invention in a cross-sectional view, figures 4a, 4b show plan views of the elastic mount in figure 3 in the area of the torque-transmitting part in different fitting steps, and figures 5a, 5b show a fastening pin according to the invention in different forms of embodiment.
Figure 1 shows an elastic mount 1 according to the invention which is embodied as a rubber-metal mount. The elastic mount 1 consists of a fastening flange 2 and a receiving flange 3 and an interposed elastic rubber element which is preferably vulcanised to the fastening flange 2 and the receiving flange 3.
The fastening flange 2 is formed by a sheet metal bracket in which a plurality of receiving bores 4a, 4b are formed with which the elastic mount can be fastened to a vehicle frame as a component of a mobile machine.
A component 5 of the part to be mounted, which for example takes the form of a driving motor or a driving cab or a driver work station of the machine, can be fastened to the receiving flange 3. To fasten the component 5 to the receiving flange 3, there is a screwed connection 6 which is formed by a fastening pin 7 which can be fastened to the elastic mount 1.
For this the elastic mount 1 comprises a fastening threaded bush 9 which is provided with a threaded bore 8, into which the fastening pin 7 can be screwed by a first fastening portion 7a which takes the form of a threaded portion and is provided with a thread. Here, the fastening threaded bush 8 can be provided with the receiving flange 3 and vulcanised on to the rubber element.
To fasten the component 5, the threaded pin 7 is provided with a second fastening portion 7b which takes the form of a threaded portion and is provided with a thread. Here, the component 5 can be fastened to the elastic mount 1 by means of a washer 10 and a fastening device 11 in the form of a nut which can be screwed on to the second fastening portion 7b.
In the axially middle area between the first fastening portion 7a and the second fastening portion 7b the fastening pin 7 is provided with a torque-transmitting part 15 which is formed on and integral with it and takes the form of a corresponding torque-transmitting shaped part 16 formed in one piece on the fastening pin 7.
The torque-transmitting shaped part 16 is arranged in a receiving opening 17 of the component 5, the receiving opening 17 being enlarged in relation to the torque-transmitting part 15 such that the torque-transmitting part 15 is arranged and mounted with play in the receiving opening 17.
Here, the thickness d of the torque-transmitting part 16 is less than the thickness h of the material of the component 5. Preferably the thickness d of the torque-transmitting part 16 is less than the thickness h of the material of the component 5 by at least half a thread pitch of the thread on the first fastening portion 7a. This makes it possible for a further turning movement to be made with a turning angle in the range of up to 900 after the fastening pin 7 is fastened loosely in the fastening threaded bush 8.
In figure 2a it can also be seen that the receiving opening 17 is enlarged in relation to the torque-transmitting shaped part 16 by the dimensions Ti and T2 which form the play between the receiving opening 17 and the torque-transmitting shaped part 16 and represent an equalisation of tolerances which allows simple fitment of the component 5 to the elastic mount 1.
However, the dimensions Ti and T2 are also such that with a turning movement of the torque-transmitting shaped part 16 -as shown by the arrow in figure 2b -the torque-transmitting shaped part 16 after a few degrees of rotation of the fastening pin 7 comes into contact through a side face or an edge with a corresponding edge face of the receiving opening 17 in order to form a means to prevent turning of the fastening pin 7 and support a fastening torque applied to the fastening pin 7 in the component 5.
Figures 5a, 5b show fastening pins 7 with different embodiments of the torque-transmitting part 15 formed by the torque-transmitting shaped part 16. According to figure 5a, the torque-transmitting shaped part 16 can be formed by a square profile section which is symmetrical in shape and exhibits edge faces of equal length. According to figure 5b, the torque-transmitting shaped part 16 is formed by a rectangular profile section which is formed symmetrically and provided with edge faces of different length.
Instead of a symmetrical design, the torque-transmitting shaped part 16 can also be of asymmetrical design.
The receiving opening 17 of the component 5 in the present embodiment example takes the form of a rectangular opening in order to obtain equalisation of different tolerances in the two directions perpendicular to one another through different dimensions Ti and T2.
It is also possible for the receiving opening to be formed square and to have the same dimensions for equalisation of tolerances in the two directions perpendicular to one another. In addition, the receiving opening 17 can be formed by a slot-like opening.
To fit the elastic mount 1 to the component 5, the fastening pin 7 in the form of a threaded stud is screwed into the fastening threaded bush 9 of the elastic mount 1 by the first fastening pin (portion) 7a. Here, the fastening pin 7 is screwed in loosely so that the fastening pin 7 is not screwed into the fastening threaded bush 9 as far as a stop but a further turning movement in the form of a turning angle in the range of approx. 90° is allowed. After the fastening pin 7 is screwed into the elastic mount 1 loosely, the component 5 with the receiving opening 17 can be fitted over the fastening pin 7 in the area of the torque-transmitting shaped part 16, as shown in figure 2a. Here, the dimensions Ti and T2 allow equalisation of tolerances and simple fitment of the parts, as can be seen in figure 2a. After fitment of the washer 10 and the fastening device 11 on the second fastening portion 7b of the fastening pin 7, a fastening torque can be applied to the fastening device 11 in the form of the nut. When the fastening pin 7 is screwed loosely into the fastening threaded bush 9 by the first fastening portion 7a, this allows the fastening pin 7 to turn initially with the torque-transmitting shaped part 16 -as shown by the arrow in figure 2b -so that the torque-transmitting shaped part 16 comes into contact through one edge with one edge of the receiving opening 17 in the component 5 to be mounted and is prevented from turning further. After the torque-transmitting shaped part 16 is supported in the receiving opening 17, a fastening torque can be built up when the parts are screwed together, during which a reaction force is absorbed through the torque-transmitting shaped part 16 directly by the component 5 to be mounted and thus the fastening torque applied through the screwed connection 6 is supported directly through the torque-transmitting shaped part 16 on the component 5 to be mounted. This means that when the component 5 is screwed to the mount 1 and thus during fitment of the component 5 to the mount 1, twisting of the elastic mount 1 and in particular of the rubber element arranged between the fastening threaded bush 9 and the fastening flange 2 can be avoided if during fitment of the component 5 this is screwed to the elastic mount 1 through the screwed connection 6.
Figures 3 and 4a, 4b show a second form of embodiment of an elastic mount 1 according to the invention. In the sectional illustration in figure 3 the construction of the elastic mount 1 is shown with the fastening flange 2, a fastening bush 20 and a rubber element 21 which can be vulcanised on to the fastening flange 2 and the fastening bush 20. The fastening flange 2 is formed by a sheet-metal bracket in which a plurality of receiving bores 4a, 4b, 4c, 4d are formed, with which the elastic mount 1 can be fastened to a vehicle frame as component of a mobile machine.
The fastening bush 20 is provided with a through bore 22 through which the fastening pin 7 extends by the first portion 7a. The fastening pin 7 can be formed according to the embodiment examples shown in figures 5a, 5b. In the present form of embodiment, the design of the torque-transmitting shaped part 16 on the fastening pin 7 and the design of the opening 17 in the component 5 to be mounted are identical to the embodiment example shown in figures 1 to 2b. In addition, the fastening of the component 5 to the elastic mount 1 by means of the washer 10 and the fastening device 11 in the form of a nut which can be screwed on to the second fastening portion 7b is also identical to figures 1 to 2b. To fasten the fastening pin 7 in the fastening bush 20, a washer 23 and a fastening device 24, preferably formed by a nut which can be screwed on to the fastening portion 7a, are provided in the region of the fastening bush 20 lying opposite the component 5. When the fastening torque is applied through the fastening devices 11 and 24 to screw the component 5 to the mount 1 and thus to fit the component 5 to the mount 1, first the fastening pin 7 turns -as shown in figures 4a and 4b -with the torque-transmitting shaped part 16 in the receiving opening 17 of the component 5 to be mounted (arrow in figure 4b) so that the fastening pin 7 is supported by means of the torque-transmitting shaped part 16 in the receiving opening 17 of the component 5, as shown in figure 4b. After the torque-transmitting shaped part 16 is supported in the receiving opening 17, a fastening torque can build up so that a reaction force is received through the torque-transmitting shaped part 16 directly by the component 5 to be mounted and thus the fastening torque applied through the screwed connection 6 is supported directly through the torque-transmitting shaped part 16 on the component 5 to be mounted. This makes it possible to avoid twisting of the elastic mount 1 and in particular of the rubber element 21 when fitting and when screwing the component 5 in place.
With the screwed connection 6 according to the invention, which is formed by the fastening pin 7 with the torque-transmitting part 15 which is received with play in the receiving opening 17 of the component 5, it is possible to obtain an equalisation of tolerances between the parts which allows simple fitment and also ensures stress-free fitment of the elastic mount when the component 5 is screwed to the mount 1.
Preferably, the mount according to the invention is used in a machine in the form of an industrial truck for mounting a driving motor, for example an internal combustion engine or an electric driving motor, which is connected with a gear box and a steerable driving wheel to form a unit, and/or a driving cab or a driver work station on a vehicle frame.
