Description

 Elastic Bearing {ELASTIC BEARING}

The present invention relates to an elastic bearing for the purpose of supporting a transmission, an engine or other units in a vehicle, and comprises an inner member, a housing, and at least one bearing spring for elastically supporting the inner member against the housing, Or the inner member and the housing are made of plastic and the housing can be securely fastened to the additional component via releasable fastening means.

This type of bearing is essentially known and the majority of bearings are used in the automotive industry, particularly for the purpose of supporting engines and transmissions.

For power transmission, it is necessary to use these bearings to attach (e.g., cure) an elastomeric bearing spring to at least one stationary portion, e.g., a housing. The housing can then be secured to the housings or power devices by being pressed into the receptacles or through the detachable connecting member.

However, in particular, metal materials and plastics are increasingly used for the housing. DE 10 2004 018241 A1 discloses a bearing of this type wherein the bearing spring is pressed against the bearing housing and the inner member is firmly attached to the bearing spring. The bearing housing and the inner member may also be made of plastic.

Similarly, DE 10 2004 054618 A1 discloses a bearing of this type, in which an outer member made of plastic is molded around an elastic bearing spring.

In the case of using plastic for the housing, the elastic bearing springs are pre-cured as discrete components, so that a plurality of bearing springs can be simultaneously produced in a single curing process due to the relatively small size of the mold cavity. Then, a housing having a larger volume can be formed around the bearing spring.

However, if the intent is to fix these types of bearings to additional components via removable fastening means (e.g., bolts), then the pressure-dependent flow and set behavior of the plastic will cause the fastening state to be permanent It will not be robust.

The object on which the present invention is based is to provide a bearing of this type which allows fastening through detachable connecting elements such as bolts, without the housing exhibiting excessive settling, even when plastic is used for the housing .

This object is achieved in that the bearing comprises a fastening strap made of a flow-resistant material, the fastening strap being characterized in that the housing comprises at least partly a fixing means To be securely fastened to the additional component and the fastening strap by means of a fastening strap.

With this arrangement, advantageously, the bearing can also be manufactured by molding plastic members on a fully cured elastomeric bearing spring. The fact that the surface pressure during fixation is not limited to the bolt-on surface so that the settleability of the plastic is completely eliminated or not important, and that it can be distributed over a large surface area, depending on the design of the fixing strap , The plastic does not flow under the load by the bolt.

According to one embodiment of the present invention, the housing is designed as a base plate and is fixed in such a way that at least one bearing spring is firmly adhered to a part of the base plate surface; The fastening strap is matched to that portion of the at least one bearing spring surface that is not connected to the base plate and is gripped around the spring in a detachably fixed position on the additional component, Lt; RTI ID = 0.0 > a < / RTI > At least one bearing spring is enclosed between the base plate and the stationary strap with / without play.

In this configuration, the fastening strap replaces a portion of the housing, and as a result, a smaller mold volume is required in bearing manufacture.

According to one embodiment of the invention, the fastening strap is made of a metallic material.

The metallic material can be well fitted to the shape of the bearing, for example through a casting process, and is particularly flow-resistant.

According to one embodiment of the present invention, the base plate has at least one hole, and the fixing strap has at least one protrusion with a hole, and the at least one protrusion of the fixing strap is fixed to the at least one hole And protrudes through the base plate to such an extent that the projection of the fastening strap is concave or coplanar with a predetermined amount relative to the surface facing the additional component.

This configuration is advantageous in that the base plate is fixed to the additional component under stress or without stress so that it moves according to the degree of concavity and such that the detachable connection is permanently rigid irrespective of the flow behavior of the base plate, Through holes in the protrusions to be directly fastened to additional components.

According to one embodiment of the present invention, even if the bearing is not fixed to the additional component, the fixing strap and the housing are connected to each other by a transport lock.

The advantage of this configuration is that the assembly process is simplified because it is impossible to lose the part.

According to an embodiment of the present invention, a conveying lock is formed by a housing provided with at least one pin, wherein the conveying lock protrudes through a corresponding hole in the fixing strap so as not to slide back through the hole of the fixing strap, It can be deformed at the end projecting from the stationary strap.

In this way, the transport lock can be implemented with little effort without additional components.

Embodiments of the present invention will be described in more detail below with reference to the drawings.

1 is a perspective view of a bearing according to the present invention;

2 is a sectional view through a bearing according to the present invention;

The elastic bearing 1 according to the present invention shown in Fig. 1 comprises an inner member 2, an elastic bearing spring 3 having two legs 4 and 5 arranged in a V-shape, a base plate 6, And a fixing strap (7). The fixing strap (7) has two fixing holes (8).

The elastic bearing spring 3 is hardened hard both on the inner member 2 and the base plate 6 of the bearing 1 and the inner member 2 is surrounded by the elastic material of the bearing spring 3. [ The fastening straps 7 can be threaded around additional components (not shown) through the fastening holes 8 and gripping around the elastomeric bearing springs 3. The inner member 2 and the base plate 6 are made of a thermoplastic material. The fixing strap 7 is made of aluminum by die casting.

2 is a cross-sectional view of the bearing 1. In Fig. The fixing strap 7 is provided with protrusions 10 through which the fixing holes 8 pass. These protrusions 10 are inserted into the base plate 6 through corresponding openings 11 in the base plate 6 and are inserted into the base plate 6 on the side facing the additional components ). ≪ / RTI >

This ensures that the flowable material is not placed between the fixing strap 7 and the additional components, while at the same time ensuring that the bearing 1 is fixed permanently and permanently to the additional element (not shown). By appropriately adjusting the length of the projections 10, it is possible to adjust the line load which allows the base plate 6 to be fixed to an additional component (not shown).

The bearing member 3 surrounding the inner member 2 and the inner member 2 within the clearance 12 are spaced apart from the bearing spring 3 as the fixing strap 7 is separated by the clearance 12. [ Lt; / RTI > If the vibration amplitude becomes too large, the fixing strap 7 acts as a stop.
