Long-wheelbase low-floor light-weight fully independent suspension passenger car

Abstract

The invention discloses a long-wheelbase low-floor light-weight fully independent suspension passenger car. A body skeleton is composed of a lower body skeleton, a front wall skeleton, a side wall skeleton, a rear wall skeleton and a roof skeleton, and each skeleton is made of aluminum alloy. A power battery pack is installed at the middle of the lower body skeleton, a front drive steering axle is arranged at the front end of the lower body skeleton, and a rear drive steering axle is arranged at the rear end of the lower body skeleton. According to the invention, the long-wheelbase low-floor structure is realized through the optimization innovation design of each system, the design and development of a light-weight suspension, and the design of the aluminum alloy body skeleton according to the characteristics of the structure of the traditional passenger car, a new energy pure electric or hybrid drive system is designed to be carried, light-weight materials are used, the passenger car has the characteristics of being green, energy-saving, high in strength, light-weight, low-floor and the like, and the passenger car has better power performance, comfort and vehicle handling performance.

Description

technical field [0001] The invention belongs to the technical field of passenger cars, and in particular relates to a long-wheelbase, low-floor, lightweight fully independent suspension passenger car. Background technique [0002] The structure of a traditional bus consists of a square (rectangular) steel pipe body frame, a front double wishbone (torsion bar shock absorber), a rear integral bridge (leaf spring shock absorber), and a fuel-powered front or rear drive system. It has a high floor design and a short wheelbase. Since it is basically made of steel or cast iron and welded or screwed, it results in low space utilization, high weight, and high fuel consumption, which is not energy-saving and environmentally friendly. Contents of the invention [0003] In view of the above-mentioned defects in the prior art, the technical problem to be solved by the present invention is to provide a long-wheelbase, low-floor, lightweight fully independent suspension passenger car. ...

[0002] The structure of a traditional bus consists of a square (rectangular) steel pipe body frame, a front double wishbone (torsion bar shock absorber), a rear integral bridge (leaf spring shock absorber), and a fuel-powered front or rear drive system. It has a high floor design and a short wheelbase. Because it is basically made of steel or cast iron and welded or screwed, it results in low space utilization, high weight, and high fuel consumption. It is not energy-saving and environmentally friendly.
