Abstract
The utility model discloses a coach frame structure comprising a frame girder. The frame girder comprises a left longitudinal beam and a right longitudinal beam which are arranged parallelly. Two vertical columns are respectively fixed at two opposite positions of the outer sides of the left longitudinal beam and the right longitudinal beam. The axis of each vertical column is perpendicular to the axis of each of the left longitudinal beam and the right longitudinal beam. The upper ends of the vertical columns as well as the lower ends of the vertical columns are connected via an upper crossbeam and a lower crossbeam, so that a closed frame structure is formed. Action force on the frame from air sacs and plate springs and the like can be borne by the aid of the closed frame structure formed by the two vertical columns, the upper crossbeam and the lower crossbeam, and meanwhile, the closed frame structure and an outer crossbeam are arranged in the same plane, and the problem of insufficient arrangement space for a power assembly can be effectively solved on the basis of guaranteeing frame strength.
Description
Technical field
The utility model belongs to the vehicle body structure technical field, relates in particular to a kind of bus frame structure.
Background technology
Large and medium-sized vehicle power train system for rearmounted rear-guard is arranged; In practical application; Owing to receive the restriction of rear overhang length and propeller shaft length; With driving engine, change speed gear box, retarder, transmission shaft and the postpone of back axle cloth, the fall crossbeam type vehicle frame is in the back leaf spring hanger of rear suspension or the crossbeam difficult arrangement at air bag mounting rail place.It is particularly evident that this kind phenomenon is reacted on the passenger vehicle of 8m～10m.At present, the retarder of the change speed gear box rear end of motor omnibus arrange almost with the outer crossbeam that air-spring bellows is installed on same X axis plane, short transverse does not have rich space yet.According to the designing requirement of vehicle frame, near crossbeam in spring block or air bag installation site, needing to arrange normally passes through connecting panel interior crossbeam and outer crossbeam front and back biasing one segment distance, reaches the purpose of avoiding retarder.Through engineering analysis, combine practical experience to get, when interior crossbeam with outside the crossbeam longitudinal separation squint when excessive, the intensity of bus frame structure will reduce significantly.
The utility model content
In view of the defective that above-mentioned prior art exists, the purpose of the utility model is to propose a kind of bus frame structure, on the basis that guarantees frame strength, can effectively solve the not enough problem of arrangement space of dynamic assembly.
The purpose of the utility model will be achieved through following technical scheme:
A kind of bus frame structure; Comprise frame beam; Said frame beam comprises left longeron and the right vertical beam that laterally arranges, and the relative position of the lateral surface of said left longeron and right vertical beam is fixed with a column respectively, and the axial line of said column is vertical each other with the axial line of said left longeron and right vertical beam; Be connected through entablatrance and cross sill respectively between the upper end of said column and between the lower end, form the closure frame structure.
Preferably, above-mentioned bus frame structure, wherein: the relative position of the lateral surface of said left longeron and right vertical beam also is fixed with an outer crossbeam respectively, and the axial line of the axial line of said outer crossbeam and entablatrance and cross sill is parallel to each other and is positioned at same plane.
Preferably, above-mentioned bus frame structure, wherein: connect through diagonal brace structure triangular in shape between said outer crossbeam of the same side and the column.
Preferably, above-mentioned bus frame structure, wherein: said entablatrance right ends horizontal-extending respectively has extending beam, strengthens diagonal brace through one between said extending beam of the same side and the outer crossbeam and is the connection of zigzag structure.
Preferably, above-mentioned bus frame structure, wherein: said entablatrance and cross sill are square steel tube.
Preferably, above-mentioned bus frame structure, wherein: the strength beam that also is provided with at least one between the said column.
Preferably, above-mentioned bus frame structure, wherein: said strength beam is a square steel tube.
The outstanding effect of the utility model is: the utility model has been cancelled interior beam structure of the prior art; The closure frame structure that constitutes through two root posts and entablatrance, cross sill; Bear the application force to vehicle frame such as air bag, leaf spring; This closure frame structure and outer crossbeam on the basis that guarantees frame strength, can effectively solve the not enough problem of arrangement space of dynamic assembly in same plane simultaneously.
Following constipation closes the embodiment accompanying drawing, the specific embodiment of the utility model is done further to detail, so that the utility model technical scheme is easier to understand, grasp.

The specific embodiment
Embodiment 1:
A kind of bus frame structure of present embodiment; Like Fig. 1～shown in Figure 3; Comprise frame beam; Frame beam comprises the left longeron 1 and right vertical beam 2 that laterally arranges, and the relative position of the lateral surface of left longeron 1 and right vertical beam 2 is fixed with column 3 respectively, and the axial line of column 3 is vertical each other with the axial line of left longeron 1 and right vertical beam 2; Be connected through entablatrance 4 and cross sill 5 respectively between the upper end of column 3 and between the lower end, form the closure frame structure.The relative position of the lateral surface of left side longeron 1 and right vertical beam 2 also is fixed with outer crossbeam 6 respectively, and the axial line of the axial line of outer crossbeam 6 and entablatrance 4 and cross sill 5 is parallel to each other and is positioned at same plane.Connect through diagonal brace 7 structures triangular in shape between outer crossbeam 6 of the same side and the column 3.Also be provided with a strength beam 8 between the column 3.Entablatrance 4, cross sill 5 and strength beam 8 are square steel tube.
The closure frame structure that present embodiment constitutes through two root posts 3 and entablatrance 4, cross sill 5; Bear the application force to vehicle frame such as air bag, leaf spring; This closure frame structure and outer crossbeam 6 are in same plane simultaneously; On the basis that guarantees frame strength, can effectively solve the not enough problem of arrangement space of dynamic assembly.
Embodiment 2:
A kind of bus frame structure of present embodiment; Structure and embodiment 1 are approximate; Difference is: as shown in Figure 4, entablatrance 4 right ends horizontal-extending respectively have extending beam 41, are the connection of zigzag structure through strengthening diagonal brace 9 between extending beam 41 of the same side and the outer crossbeam 6.
The utility model still has numerous embodiments, and all employing equivalents or equivalent transformation and all technical schemes of forming all drop within the protection domain of the utility model.
