Electric vehicle power assembly suspension system and vehicle

Abstract

The invention provides an electric vehicle power assembly suspension system and a vehicle. The electric vehicle power assembly suspension system comprises a left suspension support, a right suspensionsupport and a rear suspension support. The left suspension support, the right suspension support and the rear suspension support are all arranged on an auxiliary frame and are used for supporting anelectric vehicle power assembly. By means of the electric vehicle power assembly suspension system and the vehicle, the light weight level of the whole vehicle can be improved, the assembly efficiencycan be improved, the damping effect can be enhanced, and the matching range of rigidity can be widened.

Description

Technical field [0001] The present invention relates to the field of automobile powertrain assembly, in particular to an electric vehicle powertrain suspension system and a car having the suspension system. Background technique [0002] Due to the convenience of refueling traditional fuel vehicles, users do not have high requirements for driving range. However, electric vehicles require battery charging, which takes a long time and is inconvenient. Therefore, electric vehicles with higher driving range will inevitably be more favored by consumers. There are two important means to improve the driving range of electric vehicles. One is to reduce weight, and the other is to increase battery energy density. Increasing battery energy density often means sacrificing safety, cycle, rate performance and cost. At this stage, it has reached a great stage. bottleneck, which shows that if you want to continue to increase the driving range and enhance the competitiveness of electric veh...

AI Technical Summary

Problems solved by technology

[0005] (1) The material density is relatively high, there are many parts and components, the level of light weight is poor, and the cost is also high;

[0006] (2) When the left mount 91 and the right mount 92 are hoisting the power assembly, the left mount 91 and the right mount 92 need to be installed on the vehicle body first, and then the power assembly is hoisted, and the assembly efficiency is low;

[0007] (3) The left mount 91 and the right mount 92 are directly connected to the vehicle body through the cushion, and only the cushion is the first-level damping system, and the damping effect is limited;

[0008] (4) The rear suspension 93 is installed in the suspension installation hole 941 in the middle of the sub-frame 94, which requires high strength and rigidity of the sub-frame 94. In order to meet this requirement, it is necessary to install There are many other matching structures, which will lead to limited installation space of the rear suspension 93, and the adjustable range of the soft cushion will be reduced, resulting in a lower rigidity matching range
