Abstract

 Radiator frame for the front of the car body containing the left and right struts of the radiator frame connected directly to the upper cross member, characterized in that the radiator frame struts are rigidly connected through the frame panel to the lower cross member, forming a closed "window" shape, which is a single integral element the front part of the body, which directly connects the upper and lower cross-beams assembly with the front side members and the front wing mudguards panels, while providing a predetermined section rigidity.

Description

The utility model relates to the field of transport engineering, namely to the designs of the front of the body in the area of attachment of the car radiator, in particular passenger.

A technical solution is known for the front of the car body (RF patent No. 2354578 dated 05/11/2005 - prototype), comprising a radiator frame strut of complex angular configuration, which are connected directly to the upper radiator cross member and onto which front side members, front wing mudguards are mounted.

The objective of the invention is to increase the structural rigidity of the front of the body and the body as a whole for bending and torsion, as well as providing more reliable fastening of the components and assemblies of the car.

To solve this problem, a radiator frame for the front of the car body is proposed, containing the left and right pillars of the radiator frame, which are connected directly to the upper cross member, and through the panel of the frame, of complex spatial shape, the radiator frame pillars are rigidly connected to the lower cross member. In this case, a closed, “window” form is formed, which is a single integral element of the front part of the body, which directly connects the upper and lower crossbars with the front side members and the front wing splash guard panels, while ensuring the specified section stiffness at the interface.

Comparison of the claimed technical solution with the prior art in scientific, technical and patent documentation as of the priority date in the main and related sections shows that the set of essential features of the claimed solution was not known - therefore, it meets the patentability condition of “novelty”.

The proposed technical solution is industrially applicable, because can be manufactured industrially, efficiently, feasibly, reproducibly, therefore, meets the patentability condition "industrial applicability".

The essence of the technical solution is shown in the drawings:

Figure 1 - frame design of the radiator;

Figure 2 is an explosion diagram of the design of the radiator frame;

Figure 3 - design of the radiator frame assembly;

Figure 4 - section aa of the rack frame of the radiator;

Figure 5 - design of the radiator frame of the prototype.

The radiator frame 1 for the front of the body is a welded structure of a closed "window" shape, consisting of an upper cross member 2, a panel assembly 3, a right 4 and a left 5 pillars. The panel assembly 3 with the flange 6 is rigidly connected to the vertical wall 7 of the upper cross member 2. The vertical walls of the posts 4, 5 are rigidly connected to the side surfaces 8, 9 of the panel 3, and through the upper welding flanges of the rack 4, 5 are rigidly connected to the shelf of the upper cross member 2. The lower cross member 10 is rigidly connected to the radiator frame through the central surface 11 of the panel 3.

At the junction of the side surfaces 8, 9 of the panel 3 with the working surfaces 12, 13 of the racks 4, 5, a T-shaped section is formed (in the prototype the section is formed by one surface with flanges), which provides greater structural rigidity.

The closed form of the panel assembly 3, which connects directly the upper cross member 2 with the side members 14, 15 and the lower cross member 10, which forms a closed power structure of increased rigidity. To the upper cross member 2, on its inner side, the panels of the front wing mudguards 16, 17 are attached, locking the above power structure to the car body.

When the car is moving, the radiator frame 1 through the lateral surfaces 8, 9 of the panel 3 receives loads from road irregularities transmitted by the side members 14, 15, and through the lower welding flange 18 and the central surface 11 of the panel 3 - loads transmitted by the lower cross member 10. Racks 4, 5 connected by vertical walls to the side surfaces 8, 9 of the panel 3, form a rigid brace that transfers forces through the upper welding flanges to the upper cross member 2, which distributes the loads on the spray panels through the side guide elements 19, 20 ovikov 16, 17.

The previously mentioned rigid connection not specified in the text should be understood as spot resistance welding.

The lack of design, unlike the prototype, the spacer of the radiator frame makes it possible to install a modular cooling system. The proposed technical solution provides greater structural rigidity, increases the rigidity of the body as a whole by bending and torsion, and also provides a more reliable fastening of components and assemblies of the car, without loss of functional properties.
