Description

A mounting bracket structure for an engine tie-rod type suspension

technical field

The invention belongs to the field of automobile bodies, and specifically refers to a mounting bracket structure for an engine pull-rod type suspension.

Background technique

Among the three-point mounts, most of the rear mounts are pull-rod mounts. One end of the mount is connected to the powertrain, and the other end is connected to the body or sub-frame. There are rubber bushes at both ends of the pull-rod mount. In the car, the torsional vibration of the powertrain is mainly damped.

The engine mount can not only attenuate the vibration of the powertrain, prevent the vibration from being transmitted to the body, isolate the vibration caused by uneven road surface from affecting the engine work, but also support the powertrain, limit the movement area of the powertrain, and protect the powertrain.

For cars with FF layout, a three-point suspension structure is often used, that is, the left and right suspensions support the weight of the powertrain; the rear suspension is a tie rod type, which bears the output torque of the powertrain.

However, in the following two cases, the suspension arrangement will be difficult. 1. For some B-class cars or C-class cars, the suspension arrangement is difficult due to the large-scale structure of some systems inside the engine compartment; 2. For most cars of class A and below, the space of the engine compartment is smaller than that of class B and C cars, and it is difficult to arrange the same number of various parts and components as the large cars. At this time, you can refer to the tie-rod mount described in this article to increase the layout space of the tie-rod mount, so as to solve the problem of difficult layout.

In most cars with three-point mounts, the rear pull-rod mounts are mostly arranged according to the form shown in the figure below. As shown in Figure 1 and Figure 2, the mounting bracket is composed of two separate structures: the support beam and the pull-rod mount The installation hole of the bushing at one end, the hole 1, hole 2 and hole 3 on the bracket are first connected with the gearbox with bolts, a projection welding nut is welded on the bracket hole 4, and then the large end of the suspension cushion is connected with the front sub-frame, and the small Insert the end between the two stamping parts where the hole 4 is located, then connect the hole 4 with bolts and bring it into the projection welding nut at the same time, and finally tighten the torque. The disadvantage of this structure is that the installation structure is prone to loosening and takes up a large space.

Contents of the invention

The purpose of the present invention is to overcome the deficiencies of the prior art and propose an improved technical solution, through which the problem of tight volume inside the engine compartment can be improved.

The present invention is achieved through the following technical solutions:

A mounting bracket structure for an engine tie-rod suspension, comprising a support beam structure and a U-shaped bracket structure; the support beam structure and the U-shaped bracket structure are fixedly connected;

The support beam structure includes an inner support beam and an outer support beam; one side of the outer support beam extends outward into

Protruding structure; the part where the protruding structure connects with the supporting beam bends toward the inner supporting beam; the inner supporting beam and the outer supporting beam are provided with a first mounting hole and a second mounting hole, and the protruding structure is provided with the third mounting hole;

The bottom of the U-shaped bracket is fixedly connected with the supporting beam structure; the two side ears of the U-shaped bracket are provided with opposite fourth installation holes.

A side ear of the U-shaped bracket, the protruding structure and the plane described by the inner support beam match the shape of the side wall of the gearbox.

The first mounting hole, the second mounting hole, the third mounting hole and the fourth mounting hole are all fixedly connected to the gearbox through bolts.

The two side ears of the U-shaped bracket are respectively arranged on both sides of the bushing at the small end of the pull-rod type suspension, and are fixedly connected with the gearbox through bolts.

The beneficial effects of the present invention are:

The technical solution of the invention solves the problem that the rear pull-rod suspension cannot be arranged due to insufficient layout space of some models; compared with the current existing solution, the invention saves a projection welding nut.

detailed description

The technical solution of the present invention is described in detail below through specific examples. The following examples are only exemplary, and can only be used to explain and illustrate the technical solution of the present invention, but cannot be interpreted as limitations to the technical solution of the present invention.

As shown in FIG. 3 to FIG. 5 , a mounting bracket structure for an engine rod suspension includes a support beam structure 5 and a U-shaped bracket structure 10 ; the support beam structure 5 and the U-shaped bracket structure 10 are fixedly connected.

The support beam structure 5 includes an inner support beam 12 and an outer support beam 11, and the inner support beam 12 and the outer support beam 11 are connected by stamping; one side of the outer support beam 11 extends outward to form a protruding structure 13; The part where the protruding structure 13 connects with the support beam bends toward the inner support beam; the first installation hole 6 and the second installation hole 7 are arranged on the inner support beam and the outer support beam, and the third installation hole 7 is arranged on the protruding structure 13 Mounting holes 9; the first mounting hole is close to the rod-type suspension, and the second mounting hole is away from the rod-type suspension.

The bottom of the U-shaped bracket structure 10 is fixedly connected with the support beam structure 5 by welding; the two side ears of the U-shaped bracket structure 10 are provided with opposite fourth mounting holes 8 .

A side ear of the U-shaped bracket, the protruding structure and the surface described in the inner support beam match the shape of the side wall of the gearbox; in this implementation, a side ear of the U-shaped bracket, the protruding structure and the inner support beam. The surface described is flat.
