Description

[Detailed Description of the Invention] The present invention provides an automobile front vehicle (Vorderwagen) equipped with a running frame (Fahrschemel) and a front bumper as a support for a drive train assembly.
The traveling platform has a rear horizontal support and two lateral vertical supports protruding forward from the horizontal support, and can be separated from the vehicle body in a narrow sense both in the area of these horizontal supports and in the rows of the vertical supports. , and the vehicle body in the narrow sense is
A shock absorber accommodating portion is provided above the traveling platform, and includes two vertical supports which are curved in the direction of the vertical supports of the traveling platform and are separably connected to the vertical supports at the front end region. Regarding the vehicle in front of you. In this type of construction, known from German Patent No. 31 46 554, the longitudinal support of the traveling frame and the curved longitudinal support of the vehicle body in the narrow sense are connected to each other at their free front ends and the curved Push rod supports are also fastened to the ends of the longitudinal supports. The traveling frame is approximately U-shaped when viewed from above, and has a base passing through the horizontal supports and side legs passing through the vertical supports.
Other anterior lateral supports are missing.

In the publication, it is simply shown that the drive unit of the vehicle is fixed to the above-mentioned traveling frame. An advantage of the known design is that the carriage can be removably fixed to the vehicle bodywork from below with screws. In short, this represents the advantageous possibility of pre-assembling the drive unit on the traveling frame before it is connected to the vehicle body in the narrow sense. However, the shape of the known traveling frame makes it possible to assemble the motor block in the narrow sense, possibly together with the gearing, but without the auxiliary equipment of the drive train assembly, on the said traveling frame. It shows.

The problem of this invention is to replace the vehicle in front with the style described at the beginning.
The drive train assembly is configured in such a way that the auxiliary assemblies such as the radiator, the cooling water conditioning tank and the battery, as well as the wash water tank and/or the bumper, can be assembled from the front; The possibility of good isolation of vibrations between the assembly and the vehicle body in the narrow sense is of particular importance.

This problem is solved as follows. That is,
Both front ends of the curved vertical support are located at a distance from both ends of the vertical support of the traveling frame, which holds the bumper and is connected to the rear horizontal support via a horizontal support different from the rear horizontal support, so that the motor support is located at a distance. The rear transverse support has an upper end laterally beyond the longitudinal support, and the separable elastic joint at the upper end is in a narrow sense. The problem is solved by configuring the system to draw power into the vertical sill of the vehicle body.

Preferred configurations of the present invention are as shown in claims (2) and following claims for utility model registration. That is, the longitudinal supports of the traveling frame extend diagonally rearward and inwardly from the connection point with the curved longitudinal supports, while the curved longitudinal supports extend outwards and engage the wheels. It is advantageous if it is designed so as to enclose a pair of spaces for the supporting shock absorbers.

Further, it is preferable that the traveling frame is constructed by assembling and holding auxiliary devices of the assembly in advance, such as a radiator and a battery.

It is also advantageous for the traveling frame to be constructed by assembling and holding the front side edge plates in advance.

The longitudinal supports of the traveling frame are each separated and screwed together in front of the point of connection with the curved longitudinal support of the vehicle body, forming two longitudinally successive support parts; The front support parts of the body parts each form an underframe for the auxiliary equipment and/or the edge plates and/or components of the vehicle, together with a lateral support that is different from the lateral support of the traveling frame mentioned above. If so, it is suitable.

It is advantageous if the support part is constructed so that it can be connected from below or from the front.

Compared to the state of the art, the longitudinal support of the traveling frame extends so far in the forward direction that it holds the bumper at its front free end. This is due to the fact that a releasable connection between this longitudinal support on the one hand and the curved longitudinal support of the vehicle body in the narrow sense on the other hand is made immediately adjacent to the assembly bearing in contact with the longitudinal support of the traveling frame. , a further rearward connection between the lateral support on the one hand and the narrow bodywork, i.e. the sill, on the other hand, significantly reduces the weight of the drivetrain assembly, thereby reducing the acoustic effects. It is made very flexible in an advantageous way.

The fact that in the event of a crash, the force acting on the running frame is guided through the rear lateral support to the stability area of the vehicle body in a narrow sense, that is, to the sill, is advantageous for the crash of the front vehicle of the present invention. Causes behavior.

For the improvement of technology, the Federal Republic of Germany patent no.
In publication no. 2713604, a front vehicle is shown with two vertical supports provided on each side, as if on top of one another. From the two longitudinal supports, an upper longitudinal support with a bumper receptacle joins in the area of the lower longitudinal support at a distance from the front free end. However, all of the known structural supports are rigidly connected to each other. This means that a traveling frame, which can be disassembled, for example by unscrewing, on which the drive train assembly is preassembled together with the auxiliary assembly is not created.

Two embodiments of the present invention will be described in detail with reference to the drawings.

The traveling frame has vehicle side longitudinal supports 2 - which, as can be seen in FIG. - the vicinity of its ends is recognized simply as an end region 5 and laterally overhangs the longitudinal supports 2 - and a front transverse support 6 - a running frame which is also constructed as a support for the bumper 7 1 to fixedly connect the front free ends of the longitudinal supports 2.

From the vehicle body in the narrow sense, a left-hand sill 8, a left-hand A-post 9 and a left-hand curved longitudinal support 10 can be seen. The right side of the vehicle is naturally enantiomeric with respect to the longitudinal axis 3 of the vehicle. The curved longitudinal supports 10 each have their free ends directed in the direction of the longitudinal supports 2 of the traveling frame 1 , and the curved longitudinal supports 10 are significantly shorter than the longitudinal supports 2 of the traveling frame 1 . There is. the result,
The longitudinal support 10 is a longitudinal support of the carriage 1 which corresponds to a position remote from the free end of the above-mentioned longitudinal support 2 and immediately adjacent to the aggregate bearing 11 provided on the longitudinal support 2. It is connected to one point 12 of 2. Accordingly, the motor bearing 11 is located, viewed in the longitudinal direction, between the connection point 12 on the one hand and the shock absorber receptacle 13 for supporting the wheel force on the other hand. The shock absorber accommodating portion 13 is a curved vertical support 10
exists in contact with

As is clear from FIGS. 1 and 2, due to this structural feature, the motor bearing 11 and the weight support of the assembly are limited from the rear end of the traveling frame, that is, from the free end of the rear transverse support 4. , is also located relatively far away from the rear coupling location 14. Thereby, this connection can be made relatively flexible with the use of a rubber support - advantageous for reducing the transmission of vibrations to the vehicle body in the narrow sense.

As can be seen in FIG. 2, the longitudinal support 10 of the vehicle body in a narrow sense is curved not only at the front lower part but also toward the front inside, and as a result, this curved longitudinal support and the longitudinal support of the traveling frame 1 2 surrounds a housing space for a wheel-suspended shock absorber (not shown).

The drive system assembly is simply designated by the reference numeral 1 in FIG.
It is represented by 5. This is intended for horizontal motors. The traveling frame 1, which can be attached or detached from the lower part by, for example, screws, can be attached or detached depending on its size, in addition to a drive system assembly in a narrow sense, for example, a battery, a radiator 16 on the front lateral support 6, etc. It also has an aggregate. The front side edge plates 17 are also fixed to the traveling frame. This itself is used for water tanks.

In the embodiment of the invention shown in FIGS. 3 and 4, the traveling frame 20 is provided with a pre-installation area by subdivision of the longitudinal supports, here the left-hand longitudinal support 21 being shown. In order to expand the longitudinal support portions 22 and 23, a front frame 24 is formed which includes a longitudinal support 22 and a further transverse support 25. . Subdivision position 26
is immediately in front of the position 27 where the longitudinal support 21 of the traveling frame 20 joins the curved longitudinal support 28 of the vehicle body. The connection between the two longitudinal support parts 22 and the position 26 takes place in this embodiment by a movement of the underframe 24 from the front to the rear and by screwing in with the screw 29 .
