Seven meters of traditional Medium Bus Chassis vehicle frames adopt double; two curved longeron riveted structure, and arrangement adopts front-engine rear-drive form, without through luggage compartment in the middle part of vehicle, only has a hatchback luggage compartment at the tailstock, and volume is less, are not enough to arrange the battery needed for electric automobile.
And the medium-sized electric motor coach that most bus and coach enterprise are released at present, it being on the basis of conventional internal combustion mechanomotive force middle bus, electrokinetic cell is arranged in central frame beam or outside, the installing space of battery is limited and is difficult to change safeguard in the future.Traditional vehicle frame heavier-weight, increases complete vehicle weight so that the power consumption of car load is higher, and product does not have clear superiority further after installing electrokinetic cell additional.
Therefore, how to solve the light-weight design of vehicle frame and rational space layout, be particularly important in the development process of medium-sized electric motor coach.
Utility model content
This utility model purpose is: for the problems referred to above, it is proposed to a kind of medium-sized electric motor coach chassis lightweight body frame structure for automotive, to realize the lightweight of the chassis frame of medium-sized electric motor coach, optimizes electrokinetic cell arrangement space simultaneously.
The technical solution of the utility model is: a kind of medium-sized electric motor coach chassis lightweight body frame structure for automotive, including chassis frame, described chassis frame adopts rectangular steel pipe to be welded, this chassis frame includes the centre-line beam frame assembly of full-bearing type, described centre-line beam frame assembly includes being fixed together: be used for installing front suspension, the front overhang centre-line beam skeleton of front axle and steering, for providing electrokinetic cell installing space, undertake the stage casing centre-line beam skeleton of the part carrying effect of floor in a vehicle skeleton simultaneously, for installing the rear overhang centre-line beam skeleton of rear suspension and back axle, for installing drive motor, the back segment centre-line beam skeleton of electric air compressor and cooling system.
This utility model, on the basis of technique scheme, also includes following preferred version:
Described centre-line beam skeleton, stage casing centre-line beam skeleton, rear overhang centre-line beam skeleton and back segment centre-line beam skeleton are fixed together with welding manner.
Described stage casing centre-line beam skeleton welds formation power battery cabin with body platform skeleton and body side wall skeleton.
Ventilative louvre is left in described power battery cabin.
Described power battery cabin has two, and each power battery cabin is provided with hatch door.
Stage casing centre-line beam skeleton bottom described power battery cabin is provided with the battery slide rail of locking position-limit mechanism.
Described medium-sized electric motor coach is seven meters of long middle buses.
The total length of described chassis frame is 6650mm.
The utility model has the advantages that:
1, ensureing that reducing vehicle frame on the basis of chassis frame intensity conducts oneself with dignity, and provides one mounting means easily to electrokinetic cell simultaneously, it is ensured that it is efficient and convenient that battery overhauls and changes.
2, chassis frame adopts rectangular tube Welding Structure, the each parts in chassis can be made convenient with the connection of chassis frame, the connection support making each parts in chassis merges into a single whole with chassis frame, when alleviating chassis frame deadweight, also can reduce chassis and connect the weight of support.

Fig. 2 is the planar structure schematic diagram of this medium-sized electric motor coach chassis lightweight body frame structure for automotive of this utility model embodiment；
Wherein: 1-chassis frame, 2-front overhang centre-line beam skeleton, 3-stage casing centre-line beam skeleton, 4-rear overhang centre-line beam skeleton, 5-back segment centre-line beam skeleton.
Detailed description of the invention
Figures 1 and 2 show that a specific embodiment of this medium-sized electric motor coach chassis lightweight body frame structure for automotive of this utility model, in this example, this medium-sized electric motor coach is seven meters long medium-sized high one-level electric motor coaches, it includes chassis frame 1, whole chassis frame 1 adopts high intensity rectangular steel pipe to be welded, in the impregnable situation of intensity, greatly reducing the deadweight of vehicle frame, the total length of this chassis frame 1 is 6650mm.This chassis frame 1 includes the centre-line beam frame assembly (introduce " entirely carrying centre-line beam " structure) of full-bearing type, and described centre-line beam frame assembly includes being fixed together: front overhang centre-line beam skeleton 2, stage casing centre-line beam skeleton 3, rear overhang centre-line beam skeleton 4 and back segment centre-line beam skeleton 5.And in this example, described centre-line beam skeleton 2, stage casing centre-line beam skeleton 3, rear overhang centre-line beam skeleton 4 and back segment centre-line beam skeleton 5 are fixed together with welding manner.During practical application, all it is connected with welding manner between described centre-line beam frame assembly with each parts mounting bracket of body frame assembly and chassis.
Front overhang centre-line beam skeleton 2 is used for installing the parts such as front suspension, front axle, steering.
Stage casing centre-line beam skeleton 3 is used for providing electrokinetic cell installing space, undertakes the part carrying effect of floor in a vehicle skeleton simultaneously.When practical application, this stage casing centre-line beam skeleton 3 welds with body platform skeleton and body side wall skeleton and forms complete power battery cabin.And in power battery cabin, leave air vent, ventilation and heat during in order to normal battery operation.Further, described power battery cabin has two, and a first from left parts cloth on the right side, and each power battery cabin is provided with hatch door, and hatch door is distributed in the vehicle body left and right sides.Stage casing centre-line beam skeleton 3 bottom described power battery cabin is provided with the battery slide rail of locking position-limit mechanism simultaneously.Stage casing centre-line beam skeleton 3 instead of electrokinetic cell fixed support, and electrokinetic cell is pushed in battery flat after correct position by the battery slide rail being contained on skeleton at the bottom of the centre-line beam of stage casing in advance, and is interfixed by described locking position-limit mechanism between battery slide rail.Being built the installing space of electrokinetic cell by the rectangular steel pipe of lighter in weight, relatively transmission vehicle frame, the space that centre-line beam skeleton takies itself is less, it is possible to more reasonably utilize space, reduces weight simultaneously.Adopting this power battery cabin to be advantageous in that, when vehicle is in flame-out halted state, open the hatch door of the vehicle body left and right sides, pull out the slide rail being installed on skeleton at the bottom of battery flat, battery skids off in the lump with slide rail, can carry out quickly changing or repair and maintenance.After completing to change or overhaul, battery pushes in Vehicular battery cabin with battery slide rail, simultaneously locking hatch door, can start vehicle and travel.
Rear overhang centre-line beam skeleton 4 is mainly used in installing the vehicle chassis component such as rear suspension, back axle.
Back segment centre-line beam skeleton 5 is mainly used in installing the parts such as drive motor, electric air compressor, cooling system.
Certainly, above-described embodiment only for technology of the present utility model design and feature are described, its object is to allow people will appreciate that content of the present utility model and to implement according to this, can not limit protection domain of the present utility model with this.All equivalent transformations done according to the spirit of this utility model main technical schemes or modification, all should be encompassed within protection domain of the present utility model.
