Problems solved by technology

If each part is installed on the body separately, it cannot be arranged due to the limitation of the cabin space; if the powertrain is installed on the body through suspension, and the rest of the parts are installed on the body through brackets, the frame and parts required for collision cannot be guaranteed. Cabin Space Requirements

Embodiment 1

[0037] Such as Figures 1 to 2As shown, the present embodiment provides a powertrain installation system for an electric vehicle, which is used to install the motor 11, reducer 12, motor controller 13, compressor 14, on-board charger 15, and PTC heater in the engine compartment of the electric vehicle 16. Water pump 17 and other parts and pipelines. Among the above components, the motor 11, the speed reducer 12, the compressor 4 and the water pump 17 are moving parts, and the motor controller 13, the on-board charger 15, and the PTC heater 16 are non-moving parts. When the vehicle is accelerating, the moving parts, especially the motor 11, rotate at a relatively high speed, resulting in a large rotational force in the X direction, which easily causes the entire powertrain to overturn. Due to the large number of parts that need to be arranged, and the shapes and installation requirements are different, it is a challenge for the electric vehicle industry to set up an electric v...

Embodiment 2

[0060] This embodiment provides an electric vehicle, the engine compartment of the electric vehicle includes the electric vehicle powertrain installation system 100 designed in the first embodiment. The electric vehicle powertrain installation system 100 is connected between the left side beam 1, the right side beam 2 and the subframe 3, and is used to carry all the powertrains of the electric vehicle. The suspension assembly 5 matched with the frame 4, the suspension assembly 5 at least includes a first suspension 51 connected between the bracket 4 and the left side beam 1, a first suspension 51 connected between the bracket 4 and the right side beam 2 The second suspension 52 and the third suspension 53 connected between the power assembly and the sub-frame 3 .

[0061] By setting the electric vehicle powertrain installation system 100, the electric vehicle can integrate and install the motor, reducer and other components in the engine compartment on the same bracket 4, whic...

Abstract

The invention discloses an installing system for electric vehicle power assemblies and an electric vehicle. The installing system is connected among a left side longitudinal beam, a right side longitudinal beam and an auxiliary frame, and used for bearing all the power assemblies of the electric vehicle. The system comprises a bracket and a suspending assembly matched with the bracket, the suspending assembly at least comprises a first suspension connected between the bracket and the left side longitudinal beam and a second suspension connected between the bracket and the right side longitudinal beam, the first suspension, the second suspension and a third suspension each comprises a suspension body, a first connecting part and a second connecting part, the first connecting parts and the second connecting parts are connected to the two ends of the suspension bodies, the suspension bodies comprise first cylinders and supporting parts attached to the interiors of the first cylinders, thesupporting parts comprise second cylinders and X-type supports arranged in the second cylinders, and the second cylinders and the X-type supports are integrally arranged. By arranging the suspensionbodies with the X-type supports, the X-type supports conduct supporting in four directions, in this way, turning impact caused by operating of movement parts can be effectively resisted, and then thevibration isolation performance of NVH is guaranteed.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to an installation device for the power assembly of the electric vehicle. Background technique [0002] Nowadays, with the gradual consumption of non-renewable mineral energy represented by petroleum, energy crisis, environmental protection and sustainable development have become urgent problems to be solved in front of people. [0003] In terms of automobiles, which account for about 1 / 3 of the world's energy consumption, many countries around the world, led by developed countries such as the United States, Japan, and Europe, have invested heavily in the research and development of electric vehicles. Pure electric vehicles attract people's attention with their great advantages of environmental protection, high efficiency and sustainable development. [0004] Due to the large difference from traditional cars, electric passenger cars require a large change in design and layout in te...
