Description

A GPF mounting bracket

technical field

The utility model relates to the technical field of air intake and exhaust of automobile engines, in particular to a GPF mounting bracket that meets the overall modal and strength requirements of an exhaust system and a GPF.

Background technique

Engine pollution mainly comes from four components: PM, HCx, NOx and CO, of which PM is mostly composed of carbon or carbide tiny particles (less than 4-20 μm in size). Gasoline particulate filters (GPFs) can reduce engine soot by more than 90%, and the captured PM is then burnt out during vehicle operation.

At present, after the ordinary GPF mounting bracket is connected to the engine, the modal frequency is low, and resonance is easy to occur within the working speed range of the engine; and the structural strength of the ordinary GPF mounting bracket is low, which is prone to fatigue damage.

Utility model content

In order to overcome the above-mentioned defects in the prior art, the purpose of the present invention is to provide a GPF mounting bracket, which effectively improves the mode of the bracket and the exhaust system, and meets the overall mode and strength requirements of the exhaust system and the GPF.

In order to achieve the above purpose of the present utility model, the present utility model provides a GPF mounting bracket, comprising a GPF main body mainly composed of a cylinder and a heat shield, and both ends of the GPF main body in the axial direction are provided with an air inlet and an air outlet. , the air inlet and the air outlet pass through the main body of the GPF through a channel, and the outer wall of the cylinder is axially positioned with a first bracket and a second bracket for suppressing bending vibration and translational vibration of the engine, so The first bracket has at least two first positioning holes for positioning the engine, and the two first positioning holes are arranged along the radial direction of the cylinder; the second bracket has at least one positioning hole for the engine The second positioning hole for positioning.

The arrangement of the first bracket and the second bracket on the cylinder body of the GPF main body, which cooperate with the engine positioning, can respectively suppress the bending vibration and the translational vibration, effectively improve the mode of the bracket and the exhaust system, and meet the requirements of the exhaust system and the exhaust system. GPF overall modal and strength requirements.

In a preferred solution of the present application, the GPF main body is arranged horizontally, the first bracket is arranged on the upper end of the cylinder through a first bracket mounting plate, and the second bracket is arranged on the side of the cylinder through a second bracket installation plate Through the indirect positioning of the first bracket mounting plate and the second bracket mounting plate, on the one hand, the first bracket and the second bracket are prevented from being directly installed and positioned with the cylinder of the GPF, which will damage the cylinder and affect the function of the GPF. On the other hand, through the first bracket mounting plate and the second bracket mounting plate, the GPF cylinder can be used multiple times without the problem of accuracy or wear, and only the brackets and the mounting plates need to be replaced, which reduces maintenance costs.

In a preferred solution of the present application, the first bracket and the second bracket are integrally formed by cast iron, and the first bracket and the second bracket are provided with reinforcing ribs, which improves the overall strength of the brackets.

In a preferred solution of the present application, both the first bracket and the second bracket have two mounting holes, the first bracket is fixed on the first bracket mounting plate by two bolts passing through the mounting holes, and the first bracket is The second bracket is fixed on the second bracket mounting plate through two bolts through the mounting hole, wherein the mounting hole, the first positioning hole and the second positioning hole are all strip holes, which improve the overall installation of the GPF and the engine. craft.

Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

As shown in FIG. 1 , the present embodiment discloses a GPF mounting bracket, which includes a GPF main body 1 mainly composed of a cylinder and a heat shield. The two ends of the GPF main body 1 in the axial direction have air inlets and air outlets. The GPF main body 1 is penetrated through a channel between the air inlet and the air outlet, wherein the outer wall of the cylinder is axially positioned with a first bracket 2 and a second bracket 4 for suppressing bending vibration and translational vibration for the engine. A bracket 2 has at least two first positioning holes 22 for positioning the engine, and the two first positioning holes 22 are arranged along the radial direction of the cylinder; the second bracket 4 has at least one second positioning hole for positioning the engine hole 42.

Specifically, the GPF main body 1 is arranged horizontally, the first bracket 2 is arranged at the upper end of the cylinder through the first bracket mounting plate 3 , and the second bracket 4 is arranged at the side end of the cylinder through the second bracket installation plate 5 . The first bracket mounting plate 3 and the second bracket mounting plate 5 can be an integral structure or a separate structure, which can be fixed on the outer wall of the cylinder by spot welding. Both the first bracket 2 and the second bracket 4 have two mounting holes, the first bracket 2 is fixed on the first bracket mounting plate 3 by two bolts passing through the mounting holes, and the second bracket 4 is passed through two bolts The mounting holes are fixed on the second bracket mounting plate 5 , wherein the mounting holes, the first positioning holes 22 and the second positioning holes 42 are all bar-shaped holes to improve the installation process of the GPF mounting bracket.
