Abstract

The invention relates to a novel electric automobile two-stage vibration isolation two-dimensional adjustable suspension system which comprises a suspension support, a suspension and a balancing weight, a bolt A is installed on the top of the suspension support, the suspension support is connected with a motor through the bolt A, a bolt C is installed at the bottom of the suspension support, and the suspension is installed on the suspension support through the bolt C; the suspension is composed of a suspension shell, a suspension inner sleeve, a suspension inner rubber bushing, a suspension middle sleeve, a suspension outer rubber bushing and a suspension outer rubber bushing sleeve, and the suspension inner sleeve, the suspension inner rubber bushing, the suspension middle sleeve and the suspension outer rubber bushing are arranged in the suspension shell in sequence from inside to outside. The suspension outer rubber bushing is arranged in the suspension outer rubber bushing sleeve; a balancing weight is fixed to the suspension middle sleeve through a bolt, and the bottom of the suspension shell is connected with an auxiliary frame or a vehicle body through an E bolt. The high-frequency dynamic stiffness of the power assembly suspension system can be effectively reduced, the high-frequency vibration isolation performance is improved, and high-frequency vibration and high-frequency noise of an electric automobile are improved.

Description

[Technical field] [0001] The invention relates to the technical field of auto parts, in particular to a novel secondary vibration isolation two-dimensional adjustable suspension system for electric vehicles. [Background technique] [0002] The powertrain suspension system is the part of the car that installs the powertrain to the body and frame. The powertrain mounting system supports the powertrain, isolates the vibration and noise of the powertrain and transmits it to the passenger compartment, reduces the vibration and noise of the powertrain, and manages the force and motion displacement of the powertrain under various working conditions. Provides good NVH performance and drivability for driver and occupant. At present, there is a contradiction between the increasingly high requirements of customers on the vibration and noise performance of automobiles, and the requirement for automobile enterprises to upgrade technology and increase costs. At the same time, due to the...
