A powertrain mounting arrangement structure and its assembly method, and vehicle

Abstract

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. The suspension arrangement structure of the power assembly includes a power assembly, a suspension bracket, a steel sleeve and connecting bolts, the suspension bracket includes a first positioning hole, a first assembly hole and a second assembly hole, and the location where the second assembly hole is located Part of the first assembly hole and the first positioning hole are in a bent structure. The power assembly includes the second positioning hole, the third assembly hole and the fourth assembly hole. The connecting bolts pass through the corresponding holes to connect the power assembly. Forming and suspending the bracket, the steel sleeve is located between the first positioning hole and the second positioning hole, a part of which is embedded in the first positioning hole, and the other part is embedded in the second positioning hole. The power assembly suspension arrangement structure provided by the present application can effectively improve the positioning accuracy, avoid the situation that the assembly gap is too large or cannot be assembled, and improve the assembly stability.

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...

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
