New energy commercial vehicle chassis capable of being flexibly expanded

Abstract

The invention discloses a new energy commercial vehicle chassis capable of being flexibly expanded. The chassis comprises an underframe mechanism, the underframe mechanism further comprises a first longitudinal beam, a second longitudinal beam, a third longitudinal beam, a right longitudinal beam, a fourth longitudinal beam, a driver and a special-shaped longitudinal beam, cross beams are installed on the two sides of the underframe mechanism, the top ends of the cross beams are connected through the first longitudinal beam, the second longitudinal beam is installed on the inner side of the first longitudinal beam, the third longitudinal beam is installed on the inner side of the second longitudinal beam, the right longitudinal beam is fixedly welded to one side of the third longitudinal beam, a fixed space is formed between the right longitudinal beam and the cross beams, the fourth longitudinal beam is installed between the cross beams on the other side of the right longitudinal beam, a fifth longitudinal beam is installed on the inner side of the fourth longitudinal beam, the driver is installed at the bottom end between the fourth longitudinal beam and the fifth longitudinal beam, and the special-shaped longitudinal beam is installed at the other ends of the cross beams. The chassis has the advantages of being high in universality, high in safety, high in adaptability and high in expansibility.

Description

technical field [0001] The invention relates to the technical field of design and manufacture of new energy commercial vehicles, in particular to a flexibly expandable new energy commercial vehicle chassis. Background technique [0002] New energy commercial vehicles are the future development direction of commercial vehicles. New energy commercial vehicles mainly include pure electric commercial vehicles, extended-range commercial vehicles and fuel cell commercial vehicles. However, at present, new energy commercial vehicles are all modified on the basis of traditional fuel vehicle chassis, resulting in huge differences in the chassis schemes of different types of new energy commercial vehicles, which cannot be used universally, resulting in many types of parts and poor generalization. The adaptability and expandability of the chassis are insufficient. At the same time, since the longitudinal beam adopts a parallel straight beam scheme, the power battery is usually arrang...

Problems solved by technology

However, at present, new energy commercial vehicles are all modified on the basis of traditional fuel vehicle chassis, resulting in huge differences in the chassis schemes of different types of new energy commercial vehicles, which cannot be used universally, resulting in many types of parts and poor generalization. Insufficient adaptability and expandability of the chassis

At the same time, since the longitudinal beam adopts a parallel straight beam scheme, the power battery is usually arranged outside the longitudinal beam, and the safety is low in the event of a side collision
