Problems solved by technology

[0003] When the rear independent suspension of a bus is used as a drive axle, the connection method is relatively complicated. Since the suspension is mainly used for passenger cars, the overall size of the suspension is relatively large, requiring more space for layout, and the weight is also heavy

Abstract

The invention discloses an independent rear suspension of a pure electric four-wheel drive passenger car. The independent rear suspension is arranged on a passenger car frame, and comprises a left suspension unit and a right suspension unit, each suspension unit comprises an airbag bearing mechanism, a suspension fixing mechanism, a shock absorption and buffer mechanism, a wheel hub mechanism, a mounting block and a positioning mechanism, wherein one end of the suspension fixing mechanism is arranged on the passenger car frame, the other end of the suspension fixing mechanism is rotationally connected with the mounting block, one end of the shock absorption and buffer mechanism is hinged to the suspension fixing mechanism, and the other end of the shock absorption and buffer mechanism is fixed to the suspension fixing mechanism. The independent rear suspension of the pure electric four-wheel drive passenger car has the advantages that the structure is compact, the fixing mode is flexible, the independent rear suspension and a drive motor can be integrated in the car frame conveniently, and the lightweight of the whole car is achieved more easily.

Description

Technical field: [0001] The invention relates to a rear independent suspension of a pure electric four-wheel drive passenger car. Background technique: [0002] The suspension system of the chassis is a connection device that transmits various forces between the frame and the wheels of the car. The suspension can transmit various forces on the body and the wheels, and slow down the body vibration caused by uneven road surfaces. In the existing passenger cars, the rear independent suspension is generally used as a follower axle, and is used as the third axle in a three-axle passenger car. [0003] The connection method of the rear independent suspension of a passenger car is more complicated when it is used as a drive axle. Since the suspension is mainly used for passenger cars, the overall size of the suspension is large, which requires more space for layout, and the weight is also heavier. Invention content: [0004] The invention provides a rear independent suspension o...
