Description

Technical Field

[0001] The present invention relates to the technical field of automobile suspension systems, and in particular to a rear suspension arrangement structure for a rear-axle rear-wheel drive automobile. Background Art

[0002] The suspension is the system of tires, tire air, springs, shock absorbers, and the linkage that connects the vehicle to the wheels and allows relative motion between them. The suspension system must simultaneously support ride quality and handling / holding. It also protects the vehicle itself and any cargo or luggage from damage and wear. The purpose of a car's suspension is to maximize friction between the tires and the road, provide steering stability for good handling, and enhance passenger comfort.

[0003] When the existing rear-axle rear-wheel drive car rear suspension is driving, the shock absorber on the rear suspension provides shock absorption and cushioning for the vehicle. When the vehicle is driving on a bumpy road, the shock absorber can provide shock absorption and cushioning for the vehicle, making the passengers more comfortable. However, the rear suspension of the rear-axle rear-wheel drive car is only equipped with two shock absorbers for shock absorption and cushioning. When the vehicle needs to travel continuously for a long time, these two shock absorbers will gradually become fatigued, and the performance of key components such as the elastic elements and damping devices inside them will also decline, resulting in the shock absorption effect becoming increasingly worse. Small vibrations and impacts that could have been effectively filtered out begin to be transmitted into the interior of the car, seriously affecting the comfort of the passengers and reducing the overall driving quality.
