A motor suspension structure of a new energy vehicle

Abstract

A suspension structure of a motor of a new energy vehicle includes drive motors, two frame rails and two suspension pocket rails for mounting drive motors, the housing of the driving motor is providedwith a plurality of mounting bosses, The two suspension pocket beams are arranged in parallel on the front and rear sides, further comprising a biasing bracket for making the output shaft of the drive motor correspond to the input shaft of the rear axle and a plurality of shock absorbing devices respectively connected with the respective mounting bosses, the two suspension pocket beams are both arranged in a rearward inclined manner, and the height of the cross member located on the rear side is greater than that of the cross member located on the front side. The advantage of that invention are simple structure, Easy to manufacture, lighter weight, cost saving, strong adaptability to different rear axle elevation angles and motor models, and can solve the problems of vehicle resonance andmotor whistling caused by traditional horizontal suspension due to vibration isolation rate difference, greatly improve the noise level and ride comfort of the vehicle, and at the same time can prolong the service life of the motor.

Description

technical field [0001] The invention relates to the field of new energy vehicles, in particular to a new energy vehicle motor suspension structure. Background technique [0002] In recent years, my country's new energy automobile industry has developed rapidly under the promotion of national policies, and domestic traditional automobile companies are gradually transforming to new energy. As the powertrain of new energy vehicles, the drive motor's design and layout directly affect the power and comfort of the vehicle. The vibration of the motor mainly includes six degrees of freedom of front and rear, left and right, up and down, roll, pitch and torsion, and is often coupled with multiple degrees of freedom. The traditional motor mounts mostly adopt a horizontally arranged structure, which has insufficient rigidity and damage to the motor. The problem of poor vibration isolation rate in the left and right directions and the side tilt direction will cause vehicle resonance an...

Problems solved by technology

The vibration of the motor mainly includes six degrees of freedom of front and rear, left and right, up and down, roll, pitch and torsion, and is often coupled with multiple degrees of freedom. The traditional motor mounts mostly adopt a horizontally arranged structure, which has insufficient rigidity and damage to the motor. The problem of poor vibration isolation rate in the left and right directions and the side tilt direction will cause vehicle resonance and motor whistle during actual use, which will affect the ride comfort of the vehicle and the service life of the motor
