Description

The present invention relates to a front end for a motor vehicle according to the preamble of claim 1. Such front ends are known in many versions from the series production of motor vehicles and usually serve to attach the bumper and the associated bumper cover, but also respective add-on parts such as light units, central trim parts such as front grilles or the like, to the front end of the body or the shell of the motor vehicle. Typically, the front end includes a front end carrier, which supports the cladding and attachment parts and is attached to the respective longitudinal beams in the body shell. One problem with such front ends is creating consistent gaps and joints between the various trim and add-on parts of the front end, as well as between these parts and adjacent body panels forming the vehicle's exterior, such as hoods, fenders, and the like. Factors such as weight-related settling of the components must also be considered. For example, modern headlight units weigh approximately 10 kg each, which can cause the respective component to sag within its mounting. For this reason, a simple tolerance compensation or adjustability of the respective attachments is required. Such tolerance compensation is already provided, for example, by the EP 3 110 666 B1 known. Here, the front end comprises a front end carrier and several attachments that partially form the outer skin of the motor vehicle and are arranged on the front end carrier in an adjustable position. Furthermore, the JP 2008- 132 960 A A support structure for a vehicle body housing a heat exchanger located at the front of a vehicle. Within this support structure, the heat exchanger can be moved a predetermined distance towards the rear of the vehicle while maintaining its support state relative to the vehicle body when external force is applied from the front. Furthermore, from the EP 1 247 681 A2 A fastening device for motor vehicles is known to be attached to a first part and comprises receiving means for a positioning element of a second part in a first position with respect to the first part. Furthermore, the JP 2004- 351 959 A a rear light mounting structure for automobiles. The object of the invention is to create a front end whose respective attachment part can be adjusted in an improved manner in its position on the front end carrier. This problem is solved according to the invention by a frontend with the features of claim 1. Advantageous embodiments of the invention are the subject of the dependent claims. The front end according to the invention, which comprises a front end carrier and at least one attachment part forming the outer skin of the motor vehicle in a region and which is adjustable in its position on the front end carrier, enables an improved adjustment of the respective attachment part on the front end carrier by having a main carrier and a carrier slide adjustable relative to it, to which the at least one attachment part is attached and by means of which the attachment part can be adjusted in its position relative to the main carrier. The mounting bracket allows one or more attachments to be fixed to the front-end carrier, or more precisely, its mounting bracket, and adjusted relative to the main carrier. This enables, for example, a system supplier to pre-adjust the mounting bracket relative to the main carrier and attach attachments such as headlights and central trim panels. This pre-adjustment typically results in a precise and uniform gap pattern or dimensions with the adjacent trim panels or similar components. Should an inaccurate or inconsistent gap pattern or dimensions occur in a particular case, this can be easily corrected by adjusting the mounting bracket and the attached components relative to the components fixed or relatively fixed to the main carrier. In this way, production and manufacturing tolerances can be easily compensated for. Furthermore, in the event of a repair-related replacement of components due to damage/accidents over the vehicle's lifetime, the joint pattern for the new components can be individually adjusted in the repair shop and the The original joint quality is thus restored. Furthermore, the carrier carriage is designed as a frame with two laterally spaced vertical struts extending in the vehicle's vertical direction. Each strut has a guide for moving the carrier carriage vertically and is connected to each other at its upper and lower ends via cross struts. This results in a stable mounting and adjustment of the attachments mounted on the carrier carriage. In a further embodiment of the invention, two lighting units are attached to the support carriage as add-on components, the position of which relative to the main support can be adjusted by means of the support carriage. Thus, both lighting units can be adjusted simultaneously and uniformly relative to the main support. It is further advantageous if a trim panel, in particular a central trim panel, a radiator grille, or the like,
