Embodiment Construction

[0026] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0027] Such as figure 1 As shown, the power platform of the new bus chassis consists of four parts: the lower body frame 1, the power battery pack 2, the front drive steering axle A and the rear drive axle B. Wherein, the power battery pack 2 is installed in the middle part of the lower body frame 1, the front drive steering axle A is arranged at the front end of the lower body frame 1, and the rear drive axle B is arranged at the rear end of the lower body frame 1.

[0028] Such as figure 1 , figure 2 and Figure 4 As shown, the structure and installation method of the front drive steering axle A are as follows:

[0029] The front drive axle support 3 is a frame structure, and is preferably made of steel or aluminum alloy. The front drive axle support 3 is fixed on the lower vehicle body frame 1 . A group of front lower swing arms 4 are respectively ar...

Abstract

The invention discloses a new type of passenger car chassis power platform, which includes a lower body frame and a power battery pack. Drive axle. Based on lightweight technology and integrated design ideas, the present invention adopts an integrated design power system and four-wheel independent suspension to realize the light weight of the chassis power platform of a medium-sized bus. The passing performance under the attached road surface enhances the driving safety of the bus on the rainy and snowy road. It not only has a simple structure, compact size, small size, good handling stability, ride comfort and NVH performance, but also simplifies the production and assembly steps of the bus, effectively Increased production efficiency.

Description

technical field [0001] The invention belongs to the technical field of passenger cars, and in particular relates to a novel passenger car chassis power platform. Background technique [0002] For the Class 3 chassis of ordinary medium-sized buses, most of the steering axles do not have a driving device and use a relatively simple double wishbone structure with torsion bar springs. This type of suspension is less comfortable and has no driving function. Most of the driving axles are integral bridge type, the power is transmitted from the engine arranged at the front end of the bus to the driving axle through a long transmission shaft, and the driving axle transmits the power to the wheels on both sides. The above-mentioned structure is bulky, and the handling stability, ride comfort and NVH (noise, vibration and harshness) performance are relatively low. At present, the chassis power layout of conventional pure electric medium-sized buses also uses the above-mentioned struct...
