Automobile engine compartment front longitudinal beam

An engine compartment and front longitudinal beam technology, which is applied to vehicle components, superstructure, and subassembly of the superstructure, etc., can solve the problems of encroaching on the space of the engine compartment, increasing the workload of the welding process, inconvenient arrangement of other components, etc., and achieving a reinforced structure. Strength, the effect of optimizing the structure

Problems solved by technology

Another way is to design the engine mount mounting bracket. For example, the patent CN102101429A discloses a mounting structure for the engine mount bracket and the longitudinal beam of the vehicle body. Although this installation method can ensure the overall strength, the arrangement of the mount bracket will occupy the Part of the space in the engine compartment brings inconvenience to the arrangement of other components in the compartment, and the setting of the suspension bracket will also increase the workload of the welding process

Embodiment Construction

[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings and examples. The following examples are only used to explain the present invention, and do not constitute a limitation to the protection scope of the present invention.

[0019] Such as figure 1 , figure 2 , image 3 The front longitudinal beam of the automobile engine compartment shown includes a longitudinal beam body 1 with a C-shaped cross-section consisting of an upper plate 101, a side plate 102 and a lower plate 103. plate 2.

[0020] Two installation through holes 104 are opened on the upper plate 101 of the longitudinal beam body, and the two installation through holes 104 are arranged along the length direction of the longitudinal beam body.

[0021] Two fixing brackets 3 are provided inside the longitudinal beam body 1 , which are respectively supported and fixed between the upper plate 101 and the lower plate 103 where the mounting holes 104 of ...

Abstract

The invention discloses an automobile engine compartment front longitudinal beam which comprises a longitudinal beam body, wherein a mounting through hole is formed in the upper plate of the longitudinal beam body; a fixed bracket is arranged in the longitudinal beam body and is correspondingly fixed in a position between the upper plate and a lower plate and in the position where the mounting through hole of the longitudinal beam body is formed in a supporting manner; a mounting pipe provided with an internal thread hole is further fixedly arranged on the fixed bracket; the internal thread hole of the mounting pipe directly faces the mounting through hole of the longitudinal beam body. With adoption of the automobile engine compartment front longitudinal beam, the structural strength of the engine suspension mounting point can be ensured, and the space of the engine compartment is prevented from being occupied.

Description

technical field [0001] The invention relates to an automobile body part, in particular to a front longitudinal member of an engine compartment providing a mounting point for an engine mount. Background technique [0002] At present, there are usually two ways to design the mounting point of the engine mount: one is to weld the nut plate on the front longitudinal beam, and set the projection welding nut on the nut plate, and provide the mounting point for the engine mounting through the projection welding nut. This installation structure has high requirements for the strength of the front longitudinal beam, so in order to ensure the strength of the front longitudinal beam, high-strength plates are often selected or the thickness of the material is increased, but this will inevitably increase the difficulty of stamping the front longitudinal beam, increase the weight and Material costs. Another way is to design the engine mount mounting bracket. For example, the patent CN1021...
