Abstract
The utility model discloses a plate spring suspension chassis frame capable of realizing one-stage stepping and solves the problems that the conventional air suspension chassis is high in production cost, and a plate spring suspension chassis cannot realize one-stage stepping. The frame consists of a front suspension section at the front section, an axle distance section at the middle section and a rear suspension section at the rear section; the axle distance section comprises longitudinal channel beams on two sides; a plurality of horizontal channel beams are arranged between the longitudinal channel beams on the two sides of the axle distance section in parallel; and a plurality of longitudinal rectangular beams are inserted between the horizontal channel beams in a welding way. The plate spring suspension chassis frame is simple in structure and low in production cost and can realize one-stage stepping.
Description
Technical field
The utility model relates to a kind of chassis frame, a kind of one-level that concrete is leaf spring suspension chassis frame of marking time.
Background technology
Can realize at present the air suspension that is that one-level marks time at home and abroad in the rearmounted public transport chassis, air suspension chassis cost is higher, and most of demestic user is difficult for accepting.And leaf spring suspension chassis productive costs is low, but mainly is formed by connecting on the groove beam, and intensity is high but because its outside of belly size is big, and is higher apart from ground, thereby is difficult to realize that one-level marks time.
Summary of the invention
The purpose of the utility model is in order to solve the problems of the technologies described above, and a kind of simple in structure, one-level pedal spring suspension chassis frame that productive costs is low is provided.
This vehicle frame is made up of the wheelbase section in the front overhang section that is positioned at leading portion, stage casing and the rear overhang section of back segment; Said wheelbase section comprises the longitudinal slot beam of both sides; Also parallelly between the longitudinal slot beam of said wheelbase section both sides be provided with many transverse groove beams, be plugged with many longitudinal moment ellbeams between the transverse groove beam.
To being provided with the transverse moment ellbeam between the longitudinal moment ellbeam that is applied to install disabled person's guide plate position; The said ground Clearance to the transverse moment ellbeam that is applied to install disabled person's guide plate position and longitudinal moment ellbeam bottom surface is bigger than the ground Clearance of other rectangular beam bottom surface, preferred 50-60mm.
Said front overhang section front end runs through and adopts rectangular beam to be connected between beam and the zee beam, the inclined-plane of said rectangular beam bottom surface leading portion for making progress.
Said front overhang section both sides and wheel correspondence position are equipped with the wheel cover that supplies the arch that pipeline passes, and said wheel cover is installed on the zee beam through connecting crossbeam, also is provided with the support that is used for fixing pipeline on the said wheel cover.
Beneficial effect:
1. through parallel many transverse groove beams and many rectangular beam longitudinally is set, form several osed top rectangular configuration between the longitudinal slot beam of both sides.Because rectangular beam is little than the size of the outside of belly of groove beam, thereby can reduce the step height on chassis, and rectangular configuration can actv. guarantees the loading strength on chassis.Further; Consider that there is the demand that disabled person's guide plate is installed in later stage assembling producer; In corresponding rectangular beam and groove beam position, the bottom surface that makes rectangular beam is low than the bottom surface of the rectangular beam of other position and groove beam, has reserved corresponding disabled person's guide plate installing space like this.
2. adopt rectangular beam to be connected at zee beam with running through between the beam; For the step height that reduces the chassis is given security; Can influence the angle of passing through of vehicle frame front end simultaneously for fear of lower rectangular beam; Therefore leading portion is inclined-plane upwards in the rectangular beam bottom surface, thereby has strengthened the local angle of passing through, and satisfies and has also improved the through performance on chassis when one-level is marked time requirement.
3. the position of corresponding wheel adds the wheel cover of arch form in front overhang section both sides, can supply pipeline to pass through, and the fixed support of wheel cover can be used for restrained line, thereby avoids pipeline to pass the floor space that takies vehicle from the vehicle frame middle part like this.
4. the utility model is simple in structure, through the transformation of leaf spring suspension chassis frame, has realized that the one-level of leaf spring suspension chassis frame is marked time, and compares than the air suspension chassis and has reduced productive costs greatly, more is prone to accepted by domestic correspondent.

Fig. 2 is the utility model upward view.
Fig. 3 is the utility model block diagram.
Fig. 4 is the inclined-plane scheme drawing of the utility model rectangular beam 8.
Wherein, 1-front overhang section, 2-wheelbase section, 3-rear overhang section, 4-transverse groove beam, 5-longitudinal slot beam, 6-Z type beam, 7-run through beam, 8-rectangular beam, 9-wheel cover, 10-support, 11-longitudinal moment ellbeam, 12-connection crossbeam, 13-transverse moment ellbeam.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further explained:
Referring to Fig. 1; Chassis frame is made up of the wheelbase section 2 in the front overhang section 1 that is positioned at leading portion, stage casing and the rear overhang section 3 of back segment; Said wheelbase section 2 comprises the longitudinal slot beam 5 of both sides; Also parallelly between the longitudinal slot beam 5 of said wheelbase section 2 both sides be provided with many transverse groove beams 4; Transverse groove beam 4 adopts the mode of welding to be plugged with many longitudinal moment ellbeams 11, forms a plurality of osed top rectangular configuration, wherein; 11 of two longitudinal moment ellbeams to being applied to install disabled person's guide plate position (A portion as shown in fig. 1) are provided with transverse moment ellbeam 13, the ground Clearance of longitudinal moment ellbeam 11 and transverse moment ellbeam 13 bottom surfaces that is positioned at A portion than big 50-60mm of the ground Clearance of the bottom surface of other rectangular beam so that the later stage disabled person's guide plate is installed.As one of selectable scheme; Can the longitudinal moment ellbeam 11 at this place and transverse moment ellbeam 13 be revolved vertically and turn 90 degrees; Make flash transfer horizontal direction to by original vertical direction; Broadside transfers vertical direction to by original horizontal direction, so just can make the bottom surface of longitudinal moment ellbeam 11 and transverse moment ellbeam 13 bigger than other rectangular beam and 4 bottom surface ground Clearances of groove beam.
Said front overhang section 1 front end runs through between beam 7 and the zee beam 6 and is connected with rectangular beam 8, and referring to Fig. 4, said rectangular beam 8 bottom surface leading portions are inclined-plane 8.1 upwards.Said front overhang section 1 both sides and wheel correspondence position are equipped with the wheel cover 9 that supplies the arch that pipeline passes, and said wheel cover 9 is installed on the zee beam 6 through connecting crossbeams 12, also is provided with the support 10 that is used for fixing pipeline on the said wheel cover 9.
