[0033] The invention provides a subframe connecting bush assembly. figure 1 It is a structural schematic diagram of Embodiment 1 of a sub-frame connecting bushing assembly of the present invention; figure 2 It is a connection diagram of Embodiment 1 of a sub-frame connection bushing assembly of the present invention and the installation hole of the sub-frame bushing; image 3 It is a connection diagram of the rubber body and the lower mandrel in Embodiment 1 of a subframe connection bushing assembly of the present invention; Figure 4 It is a structural schematic diagram of the inner frame in Embodiment 1 of a sub-frame connecting bushing assembly of the present invention; Figure 5 for Figure 4 sectional view of Image 6 It is a structural schematic diagram of the middle and lower mandrel in Embodiment 1 of a sub-frame connecting bushing assembly of the present invention; Figure 7 It is a structural schematic diagram of the upper mandrel in Embodiment 1 of a sub-frame ...

Embodiment 2

[0044] On the basis of the first embodiment, the present invention provides another subframe connecting bushing assembly. Figure 9 It is a structural schematic diagram of Embodiment 2 of a sub-frame connecting bushing assembly of the present invention; Figure 10 It is a structural schematic diagram of the limit bracket in Embodiment 2 of a sub-frame connecting bushing assembly of the present invention. The structure of this embodiment is the same as that of Embodiment 1, and will not be described here one by one, as Figure 9 with Figure 10 As shown, the difference between this embodiment and Embodiment 1 is that, on the basis of Embodiment 1, this embodiment adds a limit bracket 19;

[0045] Specifically: include a limit bracket 19, the limit bracket 19 is connected with a second buffer 20, the second buffer 20 is located at the bottom of the rubber body 3, the second buffer 20 has the same effect as the first buffer 18, and also It plays the role of flexible limit, pre...

Embodiment 3

[0051] The invention also provides a sub-frame, Figure 11 It is a structural schematic diagram of Embodiment 3 of a sub-frame of the present invention. Such as Figure 11 As shown, the subframe provided by the present invention includes the subframe connection bushing assembly and the subframe body 21 provided in the first or second embodiment above, wherein the structure and working principle of the subframe connection bushing assembly and main functions have been described in detail in the foregoing embodiments 1 and 2, and will not be repeated here.

[0052] The sub-frame provided by the present invention, by setting the sub-frame connecting bushing assembly, makes the limit stroke of the sub-frame connecting bushing assembly adjustable, improves the universalization rate of parts of the sub-frame connecting bushing, and increases the overall car comfort.

Abstract

The invention provides an auxiliary frame connection bushing component, an auxiliary frame and an automobile. The auxiliary frame connection bushing component comprises a plurality of upper mandrels,a lower mandrel and a rubber part, the lower mandrel penetrates the rubber part to be in vulcanized connection with the rubber part, the upper mandrel and the lower mandrel are axially provided with first through holes and a second through hole respectively, each first through hole is communicated with the second through hole to form a shaft hole for connection with a shaft, and one of the upper mandrels different in height is selected to be coaxially connected with the lower mandrel. By replacement of the different upper mandrels, axial size variation of the auxiliary frame connection bushingcomponent is realized, and accordingly limiting stroke adjustability of the auxiliary frame connection bushing component is realized.

Description

technical field [0001] The invention relates to the technical field of automobile auxiliary frames, in particular to an auxiliary frame connecting bush assembly, an auxiliary frame and an automobile. Background technique [0002] The sub-frame and the body are connected through the sub-frame connection bushing. The main function of the sub-frame connection bush is to attenuate and filter various high and low frequency vibrations transmitted from the suspension system (sub-frame) to the body, and improve the comfort of the vehicle. sex. [0003] The outer sleeve of the existing sub-frame connecting bush is made of metal material, the inner sleeve of the sub-frame connecting bush adopts a single mandrel structure, and the inner sleeve of the sub-frame connecting bush is press-fitted into the sub-frame connecting bush In the outer sleeve of the sleeve, a subframe connecting bush is formed. [0004] However, the inner sleeve of the subframe connecting bush is usually not adjus...
