Power assembly suspension arrangement structure, assembling method thereof and vehicle

Abstract

The invention relates to the technical field of vehicles, and especially relates to to a power assembly suspension arrangement structure, an assembling method thereof and a vehicle. The power assemblysuspension arrangement structure comprises a power assembly, a suspension support, a steel sleeve and a connecting bolt, the suspension support comprises a first positioning hole, a first assemblinghole and a second assembling hole, and the portion where the second assembling hole is located, the first assembling hole and the portion where the first positioning hole is located form a bent structure. The power assembly comprises a second positioning hole, a third assembling hole and a fourth assembling hole, the connecting bolts penetrate through the corresponding holes to be connected with the power assembly and the suspension support, the steel sleeve is located between the first positioning hole and the second positioning hole, one part of the steel sleeve is embedded into the first positioning hole, and the other part of the steel sleeve is embedded into the second positioning hole. According to the power assembly suspension arrangement structure, the positioning precision can beeffectively improved, the situation that the assembling gap is too large or assembling cannot be conducted is avoided, and the assembling stability is improved.

Description

technical field [0001] The present application relates to the technical field of vehicles, in particular to a powertrain suspension arrangement structure and an assembly method thereof, and a vehicle. Background technique [0002] The vehicle powertrain is generally connected to the suspension system through the suspension bracket, so as to realize the connection between the powertrain and the body. The design of the powertrain suspension bracket not only needs to ensure the structural strength, modal and other performance requirements, but also needs to consider the coordination and positioning design with other components, otherwise it may be impossible to assemble or the assembly accuracy is low, resulting in vehicle NVH (Noise, Vibration , Harshness, abbreviated as NVH, which means noise, vibration and harshness). [0003] In order to realize the accurate positioning of the suspension bracket and the power assembly, a hole with a smaller diameter is generally designed i...

AI Technical Summary

Problems solved by technology

However, the use of small holes for positioning assembly cannot meet the requirements for assembly between components that require high positioning accuracy.

Also, complex suspension brackets may require assembly with mating parts in two different orientations

For the suspension bracket that needs to be assembled in multiple directions, after the positioning assembly in one direction is completed, due to the low positioning accuracy and the dimensional tolerance of the parts themselves, it is likely to cause the assembly of the suspension bracket in another direction. Situations that do not fit or do not fit
