Description
Technical field
The present invention relates to a kind of truss structure transition beam, belong to automobile technical field.
Background technology
With the continuous intensification of global energy crisis, in the increasingly depleted of petroleum resources and atmosphere pollution, Global Temperature
The harm aggravation risen, national governments and Automobile Enterprises are it is well recognized that energy-conservation and emission reduction are the main directions of future automobile development.
Electric automobile has as the vehicles of a new generation in energy-saving and emission-reduction, the reduction mankind to the relying party face of the conventional petroleum energy
The incomparable advantage of orthodox car.And chassis is as one of big system of automobile four, either orthodox car or new energy vapour
Car, chassis arrangement and adjustment are all highly important, and the quality of chassis arrangement and adjustment directly affects the performance and stably of vehicle
Property.
Orthodox car is upper different with new-energy automobile chassis arrangement, and new-energy automobile is arranged with " three is big on chassis
Part " and " six smallclothes " instead of the power section of orthodox car.Electrokinetic cell in new-energy automobile " three-major-items " has weight big,
The long feature of size, therefore new-energy automobile chassis rationalization arrangement is very crucial.
Current more than 5 tons of electric commercial vehicle electrokinetic cell is generally symmetrically arranged in longitudinal beam using 2 pieces of batteries
Both sides, this mode is also easy to produce fan pendulum phenomenon, vehicle is travelled jerk value aggravation, has a strong impact on vehicle cruising characteristic.
The content of the invention
Present invention aims above mentioned problem of the prior art is solved there is provided a kind of truss structure transition beam, by electricity
Pond is moderate before and after its position as wherein, making, and left and right is uniform, and center of gravity is reduced；Along with truss structure uniform force, deform small
The features such as, greatly improve vehicle cruising characteristic.
The present invention is reaches above-mentioned purpose, and the technological means used is：A kind of truss structure transition beam, in transition beam
Interior arrangement electrokinetic cell, truss structure is set to trapezium structure, separates truss structure pair according to cell shapes size and number
The lattice answered, battery is laterally as in lattice；The lap-joint of the excessive beam of truss structure and vehicle frame is attached, and in horizontal, longitudinal stress
Place sets horizontal reinforcing plate and longitudinally reinforced plate respectively, for strengthening fixing.
Further, the truss structure transition beam is formed using rectangular steel pipe by drilling, cutting, welding.
Further, the transition beam is formed with vehicle frame lap-joint by welding, bolt connection.
Further, the electrokinetic cell sets two pieces, and in the trapezium structure of truss structure, blending bolt is consolidated
It is fixed.
Further, the transition beam sets reinforcing plate U-lag, reinforcing plate U-lag and vehicle frame sheet in vehicle frame lap-joint
Body lap-joint is by being welded to connect, to increase transverse and longitudinal intensity.
As best applications example, the truss structure transition beam be applied to electric commercial vehicle chassis special small lot,
The exploitation of multi items.
Beneficial effect of the present invention is：（1）Truss structure formula transition beam is to be cut, drilled by rectangle steel, is welded,
Bulk strength is higher；（2）Truss structure uniform force, deforms small, and battery is as wherein, making moderate, left and right before and after its position
Uniformly, the stationarity of vehicle traveling is greatly improved；（3）Manufacturing process is completed by welding, simple to operate, and need not reopen mould,
Cost is relatively low；（4）Truss structure transition beam is also water route, gas circuit, the arrangement of high-low pressure wire harness provide sufficient space.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is the dimensional structure diagram of the present invention.
In figure：1st, transition beam, 2, electrokinetic cell, 3, horizontal reinforcing plate, 4, longitudinally reinforced plate, 5, vehicle frame, 6, reinforcing plate U-shaped
Groove.
