Abstract

The invention discloses a suspension system for an electric vehicle. The suspension system comprises side suspension soft cushion assemblies and a rear suspension soft cushion assembly and further comprises a front cabin crossbeam assembly and a reducing agent distribution device. The side suspension soft cushion assemblies are arranged at the two ends of the front cabin crossbeam assembly in pairs. The reducing agent distribution device comprises reducing agent tank, delivery pipeline and reducing agent delivery pumps. The side suspension soft cushion assemblies and the rear suspension soft cushion assembly are connected with the reducing agent tanks in parallel through the delivery pipelines. The reducing agent delivery pumps are arranged between the reducing agent tanks and the delivery pipelines. The arranged reducing agent distribution device can automatically infuse a reducing agent to all the suspension soft cushion assemblies, so that the elasticity of a polymer elastic material in the suspension soft cushion assemblies is restored under the effect of the reducing agent after the polymer elastic material is used for a period of time and consequently fatigued and aged due to the influences of high temperature and long-term vibration stress, it is guaranteed that all the suspension soft cushion assemblies keep the good work performance for a long time, the integration degree is high, the front cabin space arrangement is optimized, and meanwhile the damping performance is improved.

Description

technical field [0001] The invention relates to an automobile engine installation structure, more specifically, it relates to an electric vehicle suspension system. Background technique [0002] Under the current automobile industry environment, pure electric vehicles that are more environmentally friendly and energy-saving are increasingly favored by domestic and foreign OEMs, and they are stepping up research and development of electric vehicles. The power system of pure electric vehicles includes key components such as motors, reducers, controllers, and chargers. At present, most OEMs are developing electric vehicles on the basis of traditional gasoline engine models. However, due to the differences in layout and power devices, how to reasonably arrange powertrain components has become the key to the development of electric vehicles. According to the investigation, at present most of the front cabin layout of the main engine factory is to add several front cabin beams, f...
