Left suspension cushion assembly

Abstract

The invention discloses a left suspension cushion assembly. The assembly comprises a left automobile body connecting support, a left suspension cushion installation tube and a left power assembly connection support, wherein the left automobile body connecting support is connected with the periphery of the left suspension cushion installation tube in a welded mode and provided with bolt holes connected with an automobile body, the left power assembly connecting support is provided with an inserting part, and the inserting part is inserted into the left suspension cushion installation tube fromthe side of the left suspension cushion installation tube; an outer lining, a left suspension cushion and an inner lining are sequentially and fixedly arranged on the inner side of the left suspensioncushion installation tube in the radial direction from outside to inside; a rubber body layer is vulcanized at the side of the inner lining, and an anti-disengaging ring protruding outwards is arranged on the inserting part; the maximum diameter of the anti-disengaging ring is larger than the inner diameter of the rubber body layer, and the anti-disengaging ring is clamped in the rubber body layer. According to the left suspension cushion assembly, the machining precision requirement of the inserting part of the left suspension cushion support is lowered, the product qualification rate is increased, and the production efficiency is improved.

Description

technical field [0001] The invention relates to auto parts, in particular to a left suspension cushion assembly. Background technique [0002] The left suspension cushion assembly is located on the left side of the powertrain, which connects and fixes the powertrain, and at the same time isolates the vibration transmission between the powertrain and the body. The left suspension cushion assembly generally includes a left vehicle body connection bracket, a left suspension cushion installation tube and a left powertrain connection bracket, and the left vehicle body connection bracket includes a first left suspension cushion installation bracket and a second left suspension cushion Mounting bracket, the first left suspension cushion installation bracket is welded on the upper part of the left suspension cushion installation pipe, the second left suspension cushion installation bracket is two and welded symmetrically to the left suspension cushion installation pipe along the hor...

AI Technical Summary

Problems solved by technology

This kind of interference fit is difficult to control due to its large interference error, resulting in cracking and damage to the inner liner if the interference is large, and insufficient pull-out force if the interference is small, and the power assembly will appear during the driving process of the whole vehicle. If the connecting bracket falls off, the imagination of the powertrain falling will be caused, which will affect driving safety.

Therefore, the processing accuracy of the splicing part of the left suspension cushion bracket of the existing left suspension cushion assembly is relatively high, the product qualification rate is low, and the production efficiency is low.
