Suspension system used for electric vehicle, and electric vehicle comprising suspension system

Abstract

The invention discloses a suspension system used for an electric vehicle, and an electric vehicle comprising the suspension system. The suspension system comprises a power assembly and a suspension element, wherein the suspension element is provided with an auxiliary frame connecting bushing; the auxiliary frame connecting bushing comprises an upper bushing and a lower bushing; the upper bushing and the lower bushing are separably laminated and are both arranged in the suspension installation hole of the auxiliary frame; and the suspension installation hole is arranged in the body of the auxiliary frame. Therefore, by use of the above suspension element, on one hand, the auxiliary frame connecting bushing which is constructed into the split structure enables the suspension element to be simple and convenient in installation on the auxiliary frame, and therefore, the auxiliary frame and the power assembly can be simply and conveniently connected; and on the other hand, the auxiliary frame connecting bushing has a better damping and energy dissipation effect, the damping and torsion elimination effect of the suspension system can be improved, and therefore, the suspension system canmeet the use requirements of the electric vehicle.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a suspension system for an electric vehicle and an electric vehicle with the same. Background technique [0002] In the related art, most of the existing electric vehicle suspension systems are derived from traditional vehicle suspension structures. Due to the lack of pre-design and post-matching, the vibration isolation of the suspension is low during the driving process of the vehicle, which reduces the ride comfort of the occupants. [0003] In addition, due to the fact that the engine torque of a traditional vehicle has a certain climbing process, there is an idling condition, and the impact on the mount is small, and more vibration isolation performance is required for the mount. A huge torsional impact is caused, which will cause the suspension to break and pose a safety hazard. [0004] In addition, electric vehicles have no idle speed, and can output the maximum torque...

AI Technical Summary

Problems solved by technology

Due to the lack of pre-design and post-matching, the vibration isolation of the suspension is low during the driving process of the vehicle, which reduces the ride comfort of the occupants

[0003] In addition, due to the fact that the engine torque of a traditional vehicle has a certain climbing process, there is an idling condition, and the impact on the mount is small, and more vibration isolation performance is required for the mount. A huge torsional impact is caused, which will cause the suspension to break and pose a safety hazard

[0004] In addition, electric vehicles have no idle speed, and can output the maximum torque at the moment of starting, which will cause a large impact on the vehicle body during starting and braking conditions, and the suspension force is even worse

Direct misappropriation of the suspension system layout and suspension structure of the transmission vehicle cannot meet the use requirements of pure electric vehicles
