Description

Connecting bushing structure between front subframe and body

technical field

The utility model relates to a connecting bushing structure, in particular to a connecting bushing structure between a front auxiliary frame and a vehicle body.

Background technique

With the development of the economy and the improvement of people's living standards, the automobile has become one of the important means of transportation for people to travel, and the parts on the automobile are indispensable components of the automobile. The front subframe of the car is connected with the body through the front and rear points of the installation, which is one of the essential parts of the car. The traditional connection methods are all rigid connections, that is, a metal pipe kit is installed at the front and rear points of the front subframe. The metal pipe kit and the body are rigid, so that the vibration generated during driving is easy. It is transmitted to the body, making the driver or passengers uncomfortable to sit, and the comfort is low.

As mentioned above, the prior art has the following disadvantages: the front and rear points of the front sub-frame are rigidly connected to the vehicle body, vibration is easily transmitted to the vehicle body, and the comfort is poor.

Contents of the invention

The utility model solves the problems in the prior art that the installation front point and rear point of the front subframe are rigidly connected with the vehicle body, the vibration is easily transmitted to the vehicle body, and the problem of poor comfort is provided, and a front subframe capable of reducing vibration transmission is provided. Connecting bushing structure with the body.

The above-mentioned technical purpose of the utility model is mainly solved by the following technical solutions: a bushing structure connecting the front sub-frame and the vehicle body has a bushing body, which is characterized in that the bushing body includes three layers, from From the inside to the outside are the inner casing, the rubber bushing and the outer sleeve respectively, and the inner casing and the rubber bushing are connected as a whole. The rubber bushing part of the connection bushing structure is first connected with the inner bushing as a whole through vulcanization, and then the connecting body is pressed into the outer bushing to make the connection firm and weaken the pre-installation point on the original front subframe And the rigid connection between the rear point and the body, and because the elasticity of the rubber bushing has a buffering effect, the vibration transmitted from the front sub-frame to the body is reduced, and the comfort of the driver and passengers is improved.

Preferably, both ends of the inner sleeve are provided with hobbing teeth. The fine-rolled design can increase friction, prevent it from rotating on the body, and improve stability.

Preferably, the two ends of the inner sleeve are provided with outwardly protruding sleeve bosses. Both ends of the rubber bushing are provided with protruding bushing bosses. The boss of the casing is adapted to the boss of the bushing. The tight fitting design of the boss of the casing and the boss of the bushing can not only play the role of restraint, but also play the role of shock absorption due to the elasticity of the rubber bushing.

Preferably, the outer sleeve is tightly connected between the bosses of the bushes at both ends. The outer sleeve is connected with the rubber bush through the fixed connection with the boss of the bush, and the boss of the bush does not completely cover the end surface of the outer sleeve.

The utility model is ingeniously conceived, and compared with the prior art, it has the following beneficial effects through the arrangement of the rubber bushing between the inner casing and the outer sleeve:

1. Reduce the vibration transmitted from the front sub-frame to the body, and improve the comfort of the driver and passengers;

2. The setting of casing bosses and bushing bosses has the function of limiting and damping;

3. The setting of hobbing teeth on both ends of the inner casing prevents it from rotating on the body and improves stability.

Fig. 2 is a schematic diagram of the end surface structure of the inner casing in Fig. 1 .

Detailed ways

The technical solutions of the present utility model will be further described below through the embodiments and in conjunction with the accompanying drawings.

Example 1. See Figure 1 and Figure 2, this example is a connection bushing structure between the front sub-frame and the vehicle body, which has a bushing body 1, which is characterized in that the bushing body 1 includes three layers, which are respectively inner and outer from the inside to the outside. Sleeve 2, rubber bushing 3 and outer sleeve 4, the inner sleeve 2 and rubber bushing 2 are connected as a whole, and rubber bushing 3 is added between the inner sleeve 2 and the outer sleeve 4, which reduces the previous The vibration transmitted from the subframe to the body improves the comfort of the driver and passengers. And the end faces of the inner casing 2 and the rubber bushing 3 are on the same plane (as shown in Figure 1), and the two ends of the inner casing 2 are provided with hobbing teeth 5 (as shown in Figure 2), Increased friction so that it does not want to turn against the body.

Wherein, the two ends of the inner casing 2 are provided with outwardly protruding casing bosses 6, and the two ends of the described rubber bushing 3 are provided with outwardly protruding bushing bosses 7, and the said casing bosses are 6 is adapted to the bushing boss 7, one side of the bushing boss 7 protrudes toward the outer sleeve 4, and the other side has a corresponding gap 8 inward, which is for matching the upper sleeve of the inner sleeve 2 The pipe boss 6, such a matching method has the functions of position limiting and shock absorption. The outer sleeve 4 is tightly connected between the bushing bosses 7 at both ends, that is, the outer sleeve 4 is connected with the rubber bushing 3 through the fixed connection with the bushing boss 7, and the bushing The sleeve boss 7 does not completely cover the end face of the outer sleeve 4 (as shown in FIG. 1 ).

It is obvious to those skilled in the art that the present utility model can be changed in many ways, and such changes are not considered to depart from the scope of the present utility model. All such modifications obvious to those skilled in the art are intended to be included within the scope of this claim.
