The utility model adopts a three-section truss structure which comprises a transverse beam, a front section of a longitudinal beam and a rear section of a longitudinal beam, wherein, the middle section is a truss which is formed by the connection of steel pipes; the inner ends of the front section of a longitudinal beam and the rear section of a longitudinal beam are respectively connected with support pillars of the truss; supports are used for the connection between a main beam and the front section of a longitudinal beam; steel pipes are used for the connection between the main beam and a luggage chamber. The utility model solves the existing problems that the prior art has; the deformation of the whole vehicle frame is simple and free besides a large development space; the installation of the vehicle body has a favorable adaptability; the utility model can perfectly adapt to the existing complicated highway condition in China.
Description
Technical field
The utility model belongs to a kind of bus chassis, specifically relates to a kind of bus wiitth raised floor chassis.
Background technology
Frame assembly is equivalent to the skeleton of a passenger vehicle, and it is supporting the weight of car load, is the load bearing component of passenger vehicle.Simultaneously the version of frame assembly is again to the level and the profile decisive role of whole passenger vehicle.In China's passenger traffic industry, middle minibus is occupied an leading position always, along with the express highway fast development, in, long-distance high speed passenger transportation demand sharply rises, the class of passenger vehicle is also improving.Truss structure, on passenger vehicle, use with the frame assembly structure of big storage room.But present similar highland wooden handcart frame, structure are too complicated and inflexible, and limitation is big, is difficult to adapt to the variation of vehicle body.
Summary of the invention
The purpose of this utility model is the complex structure that will solve prior art, inflexible, problem that limitation is big.
The technical solution of the utility model: it comprises crossbeam, leading portion longeron, back segment longeron, it is characterized in that the stage casing is the truss that is linked by steel pipe, front and rear sections longeron the inner links with the support post 7 of truss respectively, establish brace panel between girder 4 and the front and rear sections longeron and connect, girder and storage room part link with steel pipe.In the binding of stage casing and front and rear sections, adopted the brace panel 6 of band flanging to link, four middle brace panels are riveted together the crossbeam that also install at the support place respectively with support 15 and support post.The leading portion longeron is a bathtub construction, has added one deck steel plate in the groove.First crossbeam is concordant with leading portion longeron front end, and two ends are riveted together with forward and backward longeron respectively.The back of first crossbeam is the spare tyre crossbeam, and the centre of spare tyre crossbeam has a big square opening and four mounting holes.The back segment longeron is a bathtub construction, and its big face width degree is greater than the big face width degree of leading portion longeron, and groove inside has added one deck and strengthened steel plate.The after cross member of back segment is a flute profile, the whole arc that bends to.
Structural strength of the present utility model and stability all are greatly improved, the bending resistance of two girders and torsional strength have all obtained enough assurances, owing to adopted the syllogic truss structure, make whole vehicle frame distortion simply freely, development space is very big, and its height and length can need can adjust arbitrarily in standard range by the user.

Fig. 2 is the utility model birds-eye view, wherein: 11, leading portion channel crossbar, 12, back segment channel crossbar, 13, the spare tyre crossbeam, 14, passenger vehicle passageway district.
The specific embodiment
Referring to Fig. 1,2.
The utility model adopts the syllogic truss structure, and whole vehicle frame becomes stepped appearance.Before and after it positive good utilisation of section the front and rear sections of former perforation longeron, be about to former vehicle frame and clip the middle part, keep front and rear sections, the middle part then connects with rectangular steel pipe and forms, and has formed the highland wooden handcart shelf structure of car load.Two long rectangular beams are the girders in vehicle frame stage casing, and below girder 4, design has two big storage room 5, make things convenient for passenger car to place object.
In the connection of stage casing and front and rear sections, adopted the reinforcement 6 of band flanging to link, and four middle brace panels just in time are riveted together with four supports of suspension, the effect of brace panel is embodied fully and utilize, at four point of connection places, adopt the support post of rectangular steel pipe respectively as the middle part, all adopted the less rectangular steel pipe of specification to link at two girders and storage room position, like this, in the bending resistance of two girders with antitorquely all obtained enough assurances.
The leading portion of vehicle frame is used to arrange passenger vehicle driver zone part, because passenger-carrying chassis is the engine at extreme rear chassis, so the back segment of this vehicle frame is being born the layout of total member such as driving engine, air inlet, exhaust, fuel tank then is arranged in the middle part of vehicle frame.This vehicle frame back segment is lower, has reduced the center of gravity of members such as driving engine, has increased the stability of automobile to a certain extent.In the stage casing of frame assembly, the centre of two girders has formed a passage that width is 440mm, and this passage is just in time as the passageway in the bus body, and in the both sides of passage, also provides optimized trend for various pipelines, wirning harness and reinforcement wire drawing etc.
The leading portion of frame assembly can divide to come to be seen, it mainly is made up of two longerons and several crossbeams.Longeron is made by the thick 16MnL material of 5mm, bathtub construction, length is 2255mm, added the thick steel plate of one deck 4mm at the inner stressed comparatively complicated position of longeron simultaneously, be enough to guarantee the intensity of vehicle frame leading portion, the front end of first crossbeam and longeron is concordant, and the crossbeam two ends are that rivet and the longeron of 10mm is riveted together with diameter respectively, and it plays crucial effects to improving the chassis torsion stiffness.In the back of first crossbeam, design and installation one spare tyre crossbeam, the centre of spare tyre crossbeam has a large square hole and four mounting hole site, and like this, the spare tyre of car load just can be fixed on by the support of a special use on this crossbeam.In addition, four supports of the front suspension of car load are fixed on the leading portion of frame assembly, and four flat spring brackets use rivet respectively on the longeron of vehicle frame, have guaranteed its fastness.At flat spring bracket place also design and installation the crossbeam of a flute profile, with the stiffness that guarantees vehicle frame and the suspension system stability when the motion.
The back segment of frame assembly also is made up of two longerons and several crossbeams, because back segment is stressed than the leading portion complexity, so the big face width degree of longeron is bigger than leading portion, added the thick steel plate of one deck 4mm in the longeron inside at the position of bearing driving engine, the length of steel plate has surpassed the back supporting of driving engine, to guarantee the intensity of vehicle frame back segment.The after cross member of vehicle frame is a slotted shape, and the overall beam embowment is to avoid the interference with the dynamo belt dish.Four supports of the rear suspension of car load are riveted on the longeron of this back segment because the stressed complexity in rear suspension position, at the front and back support place of rear suspension respectively design and installation crossbeam, with the torsional stiffness that guarantees vehicle frame and the stability of rear suspension motion.
