Abstract

A resilient rubber mounting, in particular an engine mounting for motor vehicles, is provided with rigid inner and outer parts to be fixed respectively to the engine casing and the vehicle frame. The rigid parts (1, 2, 3 and 4) are separated by intermediate assemblies made of rubber material of differing shock absorption properties. One assembly (9) has limited shock-absorption properties for the take up of the main load and for the damping of high frequency vibrations of small amplitude, and at least one other assembly is provided with greater shock-absorption properties for the damping of lower frequency vibrations with greater amplitude. The rigid inner part is made up of three parts, an axially inner sleeve (1) and two axially outer sleeve parts (2 and 3). The rigid outer part (4) is in a double cone-shape. The rubber assembly (9) gripping the axially inner sleeve (1) has limited shock absorption properties and is joined by vulcanisation to a cylindrical section (6) of the outer part (4), whilst the rubber assembly (10) vulcanised to the axially outer sleeve parts (2 and 3) and which has greater shock absorption properties cooperates with the outer part (4) in an adjacent and supporting manner resulting from axial bracing against the cone-shaped end parts (7 and 8) of the rigid outer part (4). <IMAGE>

Description

SPECIFICATION Resilient rubber mounting in particular engine mounting for motor vehicles The invention relates to a resilient rubber mounting suitable for use as an engine mounting for motor vehicles and the like.
A resilient rubber mounting of this sort is already known from DE-GM 80 10 569. In this resilient rubber mounting two intermediate assemblies with differing shock absorption properties are provided. One assembly has limited shock absorption property for the take up of the main load and the damping of high frequency vibration of small amplitude whilst at least one another assembly has increased shock absorption property for the damping of the lower frequency vibrations of greater amplitude.
The known resilient rubber mounting has the disadvantage that both the resilient intermediate assembly with the limited shock absorption properties as well as the assembly with increased absorption properties are vulcanized to the rigid inner and outer parts of the mounting which by its very nature involves a difficult production process.
According to the invention, there is provided a resilient rubber mounting, with a rigid inner part and a rigid outer part and intermediate assemblies between the inner and outer parts made of rubber of differing shock absorption properties, one assembly having limited shock absorption properties to take sup the main load and to absorb the high frequency vibrations with small amplitude and at least one other assembly having greater shock absorption properties to absorb the lower frequency vibrations with greater amplitude, the rigid inner part having an axially inner sleeve and two axially outer sleeve parts and the rigid outer part having a double cone-shape, the rubber assembly of limited shock absorption properties gripping the axially inner sleeve and being connected by vulcanisation to a cylindrical section of the rigid outer part, the rubber assembly of greater shock absorption properties being vulcanised to the axially outer sleeve parts and cooperating with the outer part, to absorb shocks.
Since the rigid inner part consists of an axially inner sleeve and two axially outer sleeves and is received in a double coneshaped rigid outer part with the rubber assembly of limited shock absorbing property gripping the axially inner sleeve being connected by vulcanisation with a cylindrical middle part of the rigid outer part whilst the rubber assembly with increased shock absorption property is vulcanised to the axially outer sleeve parts and cooperates with the outer part in an adjacent and supporting manner resulting from axial bracing against the coneshaped extremities, it is possible to produce the individual parts from differing rubber material more simply enabling an improved adaptation to differing loading conditions as a result of the assembly that follows and the possibility of prestressing the assembly.
If the axially inner sleeve part is formed in an oval or elliptical shape transverse to the direction of the main load, and furthermore if recesses are provided in the rubber assembly to increase yieldability, an adaptation to the predetermined loading conditions can be achieved.
If the rubber assemblies vulcanised to the axially outer sleeve parts have specific outer contours, which facilitate a predetermined assembly of the rubber material to the coneshaped extremities of the fixed outer part, an initially gently starting and thereafter progressively continuous characteristic of an engine mounting, particularly for the take up of critical start-up loads is achieved.
The rubber assembly vulcanised to the lower axially outer sleeve part can support the axially inner sleeve part by prestressing achieved through shortening the axial length of the sleeve part. As a result, excessive vibration play of the inner rubber assembly due to the limited shock-absorption property is hindered and the forward vibration of the gearbox resulting from a change of load or the impact of change of direction of travel is suppressed.
The invention is explained with the help of the embodiment shown in the drawing. It shows: Figure 1 a vertical section through a resilient rubber mounting; and Figure 2 a horizontal section along the line Il-Il in-Fig. 1.
The resilient rubber mounting shown in the embodiment consists principally of a rigid inner part which in the present case consists of three components, an axially inner sleeve 1 and two axially outer sleeve parts 2 and 3. A rigid outer part 4 is formed as a single piece, pressed metal part which has next to mounting flange 5, a cylindrical sleeve part 6 and cone-shaped end pieces 7 and 8.
The components 1, 2 and 3 forming the rigid inner part have mounted on them two different rubber assemblies with differing shock absorption properties. The axially inner sleeve 1 is associated with a rubber material 9 with limited shock absorption properties for the take up of the main load and the damping of high frequency vibrations of smaller amplitude whereas the axially outer sleeve parts 2 and 3 are associated with a rubber material 10 with higher shock absorption properties for the damping of low frequency vibrations with greater amplitude.
The rubber material 9 with limited shock absorption properties is joined to the axially inner sleeve 1 and to a cylindrical section 6 of the outer part 4 by vulcanisation.
The rubber material 10 with higher shock absorption properties is fixed in this case on the axially outer sleeve parts 2 and 3 by vulcanisation and cooperates in an adjoining and supporting manner with the cone-shaped extremities 7 and 8 of the outer piece 4.
The axially inner sleeve part 1 of the resilient rubber mounting preferably has an oval or elliptical outer contour 11 transverse to the main direction of the load in order to reduce the shearing forces at the edges of the vulcanised joints. Similarly the rubber material 9 can be provided with recesses 1 2 in order to make an increased absorption effect available in specific directions, and recesses 1 9 can be provided in outer sleeve parts which lie in the same plane as the recesses 1 2.
Assuming that the conical extremities 7 and 8 of the outer part 4 have, in an axial crosssection a circular outline, then it can be pointed out that the corresponding outer contours 1 3 and 14 of the rubber material 10 can be made so that they deviate from the axially outer sleeve parts 2 and 3 and possibly have additional ribs 1 5 or noses 1 6 which modify the impact characteristics of the rubber material in specific directions as required.
The inner sleeve 1 and the sleeve section 6 can, on receiving a higher pre-load, easily be extended into cone shape, see dotted contours 17 and 18.
The assembly of the resilient rubber mounting takes place in a conventional manner by means of threaded bolts one of which grips through the middle bore of the housing while others hold the mounting flange 5 of the outer part 4 in position.
