A suspension system of a suspension electric vehicle and a method for using the same

Abstract

A suspension system of a suspension electric vehicle comprises a mounting beam, a vibration damping mechanism, a load bearing mechanism and a torsion resistance mechanism, wherein the vibration damping mechanism is integrally mounted on one end of the load bearing mechanism, the other end of the load bearing mechanism is connected to the power system, the vibration damping mechanism is connected to the mounting beam, one end of the torsion resistance mechanism is connected to the power system, and the other end of the torsion resistance mechanism is connected to the subframe. The load-bearingelement skeleton I and skeleton II are arranged on both sides of the power system, the damping element I is arranged on the skeleton I, and the damping element II is arranged on the skeleton II, so that the mounting beam is more force-bearing and the structure is more stable. By adjusting the direction of the rubber bushings in the damping element I and the damping element II, the stiffness of theentire suspension system in all directions is more reasonable, the limit capacity of the suspension system to the dynamic system is improved. The vibration damping element I is arranged on the frameI and the vibration damping element II is arranged on the frame II, so that the force on the mounting beam is more reasonable and the structure is more stable. The design of the anti-torsion mechanismimproves the anti-torsion ability of the whole system. The invention also discloses a method for using the suspension system of the suspension electric vehicle.

Description

technical field [0001] The invention belongs to the technical field of auto parts, and in particular relates to a suspension type electric vehicle suspension system and a use method thereof. Background technique [0002] As family cars become more and more popular between people's life and work, the development of the automobile industry is also faster and faster, and energy issues are paid more and more attention to by everyone, and electric car cars emerge as the times require. At present, the development of electric vehicles is basically remanufactured from traditional fuel vehicles, that is, the body, interior and exterior, chassis and other systems are the same as those of traditional vehicles, with corresponding changes in power systems and electrical systems. However, since the power system of an electric vehicle adopts a combination of drive motor + reducer, the volume is much smaller than that of a traditional vehicle's engine + gearbox. At the same time, the instan...

Problems solved by technology

However, since the power system of an electric vehicle adopts a combination of drive motor + reducer, the volume is much smaller than that of a traditional vehicle's engine + gearbox. At the same time, the instantaneous torque of the motor is large, and the layout of the front cabin and the power system are resistant to torsional vibration. There have been some difficulties
