Embodiment Construction

[0034] In order to make this structural scheme clearer, this paper uses a 6.84-meter fully-loaded pure electric mid-bus chassis structure as a specific description:

[0035] A general-purpose pure electric passenger car underframe structure, the underframe is a truss structure welded by rectangular steel pipes, which includes a front section 1 of the underframe, a middle section 2 of the underframe, and a rear section 3 of the underframe connected in sequence along the front and rear directions.

[0036] The underframe front section 1 includes three horizontal truss structures connected to each other and parallel to the yoz coordinate plane of the vehicle body coordinate system and the front axle.

[0037] The middle section 2 of the chassis is composed of four longitudinal trusses I, II, III, VI4, 5, 6, 7 and four transverse trusses I, II, III, VI8, 9, 10, 11 parallel to the yoz coordinate plane, The distance between adjacent transverse trusses may be between 800-850 mm, and ...

Abstract

The invention relates to a truss underframe structure applicable to bearing and non-bearing pure-electric buses. The universal pure-electric bus underframe structure includes an underframe front segment (1), an underframe middle segment (2) and an underframe rear segment (3), the underframe middle segment (2) is of complete truss structure, and fixed oblique supports (19) for a floor layer (12) and a lower floor layer (13) of the underframe middle segment (2) are staggered. Front and rear ends of a longitudinal truss I (4) ends at an axle (16), longitudinal trusses II and III (5) and (6) are of keel structure passing through a whole underframe, front and rear ends of a longitudinal truss VI (7) ends at the axle (16), the middle of the longitudinal truss VI (7) breaks at a door step (17). The longitudinal truss III (6) uses the fixed oblique supports (19), and the longitudinal trusses I, II and VI (4), (5) and (7) use tensioner type moving oblique supports (14).

Description

technical field [0001] The patent of the present invention relates to the field of bus body structure design, in particular to a truss-type underframe structure that can be applied to load-bearing and non-load-bearing pure electric buses at the same time. technical background [0002] With the rapid development of railway vehicles such as high-speed trains, long-distance highway buses parallel to them are gradually being replaced, and the sales volume of short- and medium-distance buses complementary to them is increasing year by year. And with the intensification of global energy and environmental crisis, pure electric bus has become a key research object because of its many advantages. [0003] At present, the research on the structure of pure electric buses in my country is still at a low level. Basically, the powertrain is replaced on the basis of the structure of traditional internal combustion engine buses and the existing structure is partially modified, resulting in ...
