Description

[Detailed Description of the Invention] The present invention relates to a vehicle body side support structure for a spring suspension system or a spring damper of a motor vehicle, as set forth in the generic concept of claim (1) of the registered utility model claim.

Federal Republic of Germany Patent No. 2435723 and German Patent No. 2745380 disclose a vehicle body side support structure equipped with thrust receiving rubber vulcanized and bonded to the inner and outer panels, and the support structure includes an outer panel and an inner panel. The rubber metal support body is fastened to the vehicle body with bolts via the flange.

The present invention provides the above-mentioned vehicle body side support structure, while maintaining the advantageous spring device or damper characteristics inherent to the thrust receiving rubber, while maintaining the spring suspension device or damper, or the axle supplemented by the spring suspension device or damper. The challenge is to enable automatic attachment.

This problem is solved as follows. That is,
Vehicle body support structures for spring suspensions or spring dampers of motor vehicles with a rubber-metal support acting between the vehicle body and the suspension, which support may also serve as an intermediate connection for roller bearings or plain bearings. It consists of an inner plate connected to a spring suspension system, an outer plate connected to the vehicle body, and a rubber element that is vulcanized and bonded between the inner and outer plates and mainly receives pressing force. It is inserted into a support receptacle molded inside the vehicle body according to the dimensions of the outer panel, and is housed therein in a shape-restricted manner in the direction of contraction of the spring and in a direction perpendicular thereto.
In a vehicle body support structure in which the outer skin and the support receptacle have a shape that tapers upward, the cone angle of the outer skin and the support receptacle is at least self-stopping, and the outer skin springs within the support receptacle. The above-mentioned problem is solved by adjusting it so that it is held only by frictional engagement in the direction of elongation.

Other configurations of the present invention are described in the claims for utility model registration as embodiments.

It is well known that a vehicle supports a spring suspension on the vehicle body side without bolts between a spring suspension bearing containing a rubber element and the vehicle body. It is not a thrust receiving rubber that can completely receive the thrust. Here, a ring-shaped rubber is used, which on the one hand is attached to a metal receiver fixed to the damper piston, and on the other hand is pushed into and supported by a rotationally symmetrical outer plate integrated into the car body. There is. The spring action and damping action of such a support structure is only slightly lower than that of a complete and fully vulcanized thrust receiver. The unbonded rubber must be placed in a form-constrained manner within the structural parts to be connected.
This rubber is therefore subjected to compression, and as a result its properties are much steeper than in forms which are subjected primarily to shear forces.

The present invention will now be described in detail according to the illustrated embodiments.

The applied rubber-metal support is, as is known,
It consists of an inner plate 1b and an outer plate 1c, between which a rubber element 1a is vulcanized and bonded. The lower end of the outer plate 1c is bent outward into a shoulder shape. In the exemplary embodiment, the rubber metal carrier is designed rotationally symmetrically, the inner plate 1b being cylindrical and the rubber element 1a having a ring shape. The outer plate 1c has a conical shape that tapers upward, and a thin rubber cover 1d is placed on the outside.
is covered.

As shown in FIG. 2, a support receptacle 2a is formed on the vehicle body part 2 of the automobile, and this support receptacle 2a
The outer plate 1c is inserted from below. The shape and dimensions of this support receiver 2a are adapted to the outer shape and dimensions of the outer panel 1c. That is, in the embodiment, the support receiver 2a is rotationally symmetrical and has an upwardly tapered conical shape, so that the outer plate and the support receiver are in close contact and frictionally engaged with each other. The skin is held within the support receiver without additional fastening means.

The shoulder portion 1e bent outward is in contact with the vehicle body from below.

For mounting a suspension device or a suspended damper, the rubber-metal support 1 is pre-mounted via a roller or plain bearing 10 at the upper end of the piston rod 6 of the damper with a sleeve nut 7 and then lowered in the usual manner. The side stoppers 5 can be attached together.

Due to the purposeful design of the support receptacles in the outer skin as well as in the vehicle body, the suspension or damper can be shaped in a simple manner manually or automatically from below into the support receptacle 2a as part of the preassembled axle structure. It becomes possible to insert it closely.

Advantageously, the cone angles of the outer skin 1c and the support aperture 2a are selected in such a way that they are at least wedged against each other and thus remain connected even under extreme operating conditions to prevent detachment of the outer skin from the support aperture. . Outer panel 1
A rubber cover 1d provided outside c compensates for the errors that actually occur and removes the noise that can be expected.

After inserting the suspension into the vehicle body, the upper plate 3 is screwed with nuts 4 in a known manner.

Basically, the rubber metal support 1 and its support receiver 2 do not necessarily have to be formed rotationally symmetrically, but
In this case, manufacturing costs increase.

In such cases, too, in order to facilitate automatic installation, the skin and its supports have an upwardly tapered shape, in which case the taper angle of the skin and its supports can be advantageously self-restricted. It is formed like this.

The support structure of the suspension system to the vehicle body according to the present invention is as follows:
It allows automatic mounting of the suspension system, is particularly simple in structure, and has spring and damper characteristics that ensure good riding comfort.
