Abstract

The invention discloses a structure for reducing the equivalent unsprung mass of a single cross arm suspension wheel-side electric driving system; an elastic rubber is supported on a rack in a hinging way; one end of an oscillating arm of a single cross arm suspension is connected with the elastic rubber in a hinging way; the other end of the oscillating arm of the single cross arm suspension is connected with an electric machine which is fixedly arranged on a speed reducing case; the speed reducing case is connected with a half shaft sleeve pipe; a power output end of the electric machine isconnected with a pinion gear which is meshed with a main gear; the main gear is connected with the half shaft sleeve pipe; and after the electric machine is decelerated by the gears, the power is output to rims so as to drive wheels. The distance from the mass center of parts which are not concentric with the wheels to the oscillation central axis of the single cross arm suspension is reduced, namely, the equivalent unsprung mass is reduced. The structure has the advantages of reducing the equivalent unsprung mass of the wheel-side driving system so as to increase vibration frequency of the wheels, reduce resonance vibration and impact and vibration from road surfaces and improve smoothness of automobile driving.

Description

technical field [0001] The invention relates to the field of electric vehicle chassis and transmission, in particular to a structure and method for reducing the equivalent unsprung mass of a wheel-side electric drive system of a single-wishbone suspension. Background technique [0002] The size of the car's unsprung mass (unsprung mass) affects the driving safety and comfort of the car. At present, the wheel-side electric drive system represented by electric wheels has become a research hotspot due to its simple drive system and vehicle structure, high transmission efficiency, and independent control of the torque of each drive wheel, which is conducive to improving driving performance under harsh road conditions. . But because the motor is installed in the drive wheel, the unsprung mass of the car will be increased. [0003] In the past, when calculating the unsprung mass of a car, the mass of all parts in the wheel was directly regarded as the unsprung mass. But in fact...
