Problems solved by technology

[0005] In an offset collision, this design will cause the suspension system to be unstable and fail, and the following three situations may occur: the suspension rear bracket of the stamping part is basically not deformed, and the collision space at the rear of the powertrain cannot be fully utilized; or the powertrain The connection point of the front bracket and the rear bracket is used as the reference point to rotate, and the rotation cannot be controlled in this case, which may increase the intrusion of the firewall; the rear bracket may be twisted and deformed

Embodiment 1

[0043] This embodiment provides a powertrain suspension rear bracket, such as figure 1 and figure 2 As shown, it includes a first assembly and a second assembly, wherein the first assembly includes a lower plate 1, and the first end 20 of the lower plate 1 is bent and extended to the second end 19 of the lower plate 1 to form an upper plate 2; image 3 , 4 , 7, and 8, the upper plate 2 and the lower plate 1 are respectively provided with a first opening 11 and a second opening 12 at corresponding positions, and the lower plate 2 is also provided with a first long groove 4; as Figure 5 and Figure 6 As shown, the second assembly includes a plate part 3, and the second long groove 5 and the third opening 13 are opened on the plate part 3; the plate part 3 is located between the upper plate 2 and the lower plate 1, and the first fastener passes through the second An opening 11, a second long slot 5 and a second opening 12 are fixed on the upper plate 2 and the lower plate 1,...

Embodiment 2

[0058] This embodiment provides a powertrain suspension failure mechanism, such as Figure 9-11 As shown, it includes the suspension front bracket 18 and the powertrain suspension rear bracket provided by Embodiment 1. The second assembly of the suspended rear bracket is connected to the first end of the suspended front bracket 18, the first assembly of the suspended rear bracket is suitable for connecting with the subframe, and the second end of the suspended front bracket 18 is suitable for connecting with the gearbox Shell connection. Such as Figure 9 and 12 As shown, the suspension front bracket 18 is provided with three seventh openings 16, and the suspension front bracket is connected with the gearbox housing through the seventh openings 16 and matching bolts.

[0059] The beneficial effect of this embodiment is based on the powertrain suspension rear bracket provided by the first embodiment, so the beneficial effect is the same as that of the first embodiment, and w...

Abstract

The invention provides a powertrain suspension rear bracket and a powertrain suspension failure mechanism, the suspension rear bracket includes a first component and a second component, the first component includes a lower plate, and the first end of the lower plate faces the second The two ends are bent and extended to form an upper plate; the upper plate and the lower plate are respectively provided with a first opening and a second opening at corresponding positions, and the lower plate is also provided with a first long groove; the second component includes a plate part, a plate A second long slot and a third opening are opened on the upper part; the plate part is located between the upper board and the lower board, and the first fastener passes through the first opening, the second long slot and the second opening and is fixed, and the second The fastener passes through the third opening and the first slot and is fixed, the second fastener is suitable for moving in the first slot, and the first fastener is suitable for moving in the second slot, so that the lower plate The second end is far away from or close to the plate portion. The suspension rear bracket of the power assembly provided by the invention makes the automobile fail in the same failure mode when the front part is collided, and the suspension rear bracket will not be deformed or twisted.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a power assembly suspension rear bracket and a power assembly suspension failure mechanism. Background technique [0002] The suspension system is an automotive powertrain used to reduce and control the transmission of engine vibration and play a supporting role. The suspension system generally includes a front bracket and a rear bracket, and the front bracket and the rear bracket are connected by nuts. [0003] Due to the weak strength of the casting bracket, the rear suspension and rear brackets of general models are all designed as stamping parts. [0004] In the process of realizing the present invention, the inventor has found that there are at least the following problems in the prior art: [0005] In an offset collision, this design will cause the suspension system to be unstable and fail, and the following three situations may occur: the suspension rear bracket of the ...
