Abstract

The invention discloses a vehicle suspension control arm based on an array type shock absorber. The control arm comprises a control arm body, an array type shock absorber and a control arm connectingassembly, wherein the control arm body is the most basic structural component of the vehicle suspension control arm and used for bearing loads in the vehicle running process and providing an installation base for the array type shock absorber and the control arm connecting assembly; the array type shock absorber is installed on the control arm body and used for absorbing vibration and impact transmitted to a vehicle body from a running system in the vehicle running process; the control arm connecting assembly is installed on the control arm body and connected with a vehicle driving system anda vehicle body. The vehicle suspension control arm is used for attenuating impact and vibration transmitted to a chassis by a driving system through the array type shock absorber arranged in the control arm in the driving process of a vehicle. Therefore, the vibration acceleration energy and amplitude of the vehicle are reduced as much as possible on the premise of not obviously increasing the structural complexity and the curb weight of the vehicle suspension system.

Description

technical field [0001] The invention relates to the vibration reduction of vehicle parts, in particular to a vehicle suspension control arm with a vibration reduction structure and a parameter calculation method. Background technique [0002] The NVH characteristics (noise, vibration and roughness) of the vehicle during driving have a very important impact on the ride comfort of the vehicle. Among them, road noise is an important part of vehicle vibration noise. During the driving process of the vehicle, the tires are in direct contact with the road surface, and the vibration shock generated by the uneven road surface is transmitted to the vehicle body through the driving system and suspension system, so it is very difficult to reduce the vibration and noise of road noise. The method of attenuating and blocking vibration shock without significantly increasing the complexity and quality of the suspension system has always been the focus of industry research. [0003] At thi...
