Abstract
The utility model relates to a car frame of a car, which is composed of front end car frame, a back end car frame and a middle ridge beam supporting frame. The front end car frame and the back end car frame are side beam type. The middle ridge beam supporting frame comprises one-two longitudinal middle beams and at least four transverse branch beams, and the longitudinal middle beams and the transverse branch beams are fixedly connected. The longitudinal middle is supported and arranged on each transverse branch beam. At least two transverse branch beams are respectively transversely supported and arranged on two longitudinal beams of the front end and the back end car frames and the transverse branch beams are fixedly connected with the longitudinal beams. When the longitudinal middle beams of the middle ridge beam supporting frame are provided with two, the longitudinal middle beams are mutually parallel between the two longitudinal middle beams and are fixedly connected a transverse beam. The outside width of the two longitudinal middle beams is smaller than the outside width of the longitudinal beams of the front end and the back end car frames. The utility model has the advantages of simple structure and easy fabrication, and sufficient space under a floor of a passenger car carriage can be obtained for placing larger luggages.
Description
The utility model relates to the vehicle frame of automobile.
Existing many passenger vehicles, what its vehicle frame adopted is autotruck straight frame commonly used, article two, side bar passes through full car, because the obstruction of crossbeam, the space below floor compartment is less, is difficult to arrange interior environment system and bigger baggage container, so, baggage rack often is arranged on carriage top and compartment internal upper part, and this not only can make the center of gravity of automobile raise, and vehicle body will bear heavier load.Utilize the grid type vehicle body framework construction, but cloth deposits big baggage container below floor compartment, but its complex structure, the manufacturing technique requirent height, the production cycle is long.
The purpose of this utility model is a backbone tray frame in the passenger vehicle that will provide a kind of simple in structure, easy to manufacture, and it makes has enough spaces to be arranged bigger baggage container below the passenger car floor.
The purpose of this utility model is to adopt following measure to realize.
The utility model is made up of leading portion vehicle frame, back segment vehicle frame and median ridge boom support, leading portion vehicle frame and back segment vehicle frame are the side bar formula, the median ridge boom support comprises that 1～2 vertical central sill and at least 4 proppings are composed of a fixed connection, vertically central sill is erected on each crossbeam, at least respectively have two proppings respectively transverse strands be located on two longerons of leading portion vehicle frame and back segment vehicle frame and captive joint with it.
When vertical central sill of central spine support is designed to two, two vertical central sills be parallel to each other and two vertical central sills between be fixedly connected with crossbeam, two vertical central sill outside widths are less than the longeron outside width of leading portion vehicle frame and back segment vehicle frame, satisfying under the condition of strength and stiffness, two vertical central sills of median ridge boom support should be drawn close to central authorities as far as possible, so that there is bigger space both sides under the floor compartment.
Mainly in order to front suspension, rear suspension, driving engine and other assemblies of chassis to be installed, body framwork is erected on the median ridge boom support for leading portion vehicle frame and back segment vehicle frame.
Advantage of the present utility model:
1, vertical central sill of median ridge boom support is overhead highly big, and width is less than the width of leading portion vehicle frame and back segment vehicle frame, and making has enough spaces to be arranged bigger baggage container and air conditioner between two axletrees under the floor compartment;
2, simple in structure, easy to manufacture, productive costs is low;
3, can combine with the front and rear sections vehicle frame after the installation vehicle body finishes on the median ridge boom support again, the production on vehicle body and chassis can independently be carried out simultaneously separately, shorten the production cycle, turnover of funds is accelerated;
4, be easy to carry out the modularization design, satisfy the client the different configuration requirements of vehicle body with the chassis;
5, vehicle body and chassis separation of produced to the influence of chassis quality, have reduced waste of power when having avoided car body coating simultaneously.
Below in conjunction with the embodiment accompanying drawing the utility model is further described.
Fig. 1 is the example structure scheme drawing, among the figure solid line figured be the utility model, down with;
Fig. 2 is the birds-eye view of Fig. 1;
Fig. 3 is the left view of Fig. 1.
The present embodiment vehicle frame is made up of leading portion vehicle frame 1, back segment vehicle frame 2 and median ridge boom support 3, and leading portion vehicle frame 1 is the side bar formula, its length be from the vehicle frame front end backward to the rear spring bearing of front suspension steel spring; Back segment vehicle frame 2 also is the side bar formula, and its length is to the vehicle frame rear end before the front spring bearing from the rear suspension steel spring; Median ridge boom support 3 is by two vertical central sills 301 and 302, crossbeam 303 between two vertical central sills, article 4, propping 304,305,305,307 and transverse bracket 308,309 are welded, each beam is box girder, two vertical central sills 301,302 are erected at propping 304 parallel to each other, 305, on 306 and 307, the wide 400mm in the outside, the wide 860mm in the two longerons outside of leading portion vehicle frame 1, the wide 860mm in the two longerons outside of back segment vehicle frame 2, propping 304,305 respectively transverse strands be located at before the leading portion vehicle frame 1 front axle position top, after two longerons above, propping 306,307 respectively transverse strands be located at before the back segment vehicle frame 2 back axle positions tops, after two longerons above, and with bolt captive joint with it, transverse bracket 308,309 are welded on two vertical central sills 301 respectively, 302 the outside.
