Description
Technical Field
The utility model belongs to electricelectric moves city bus, especially relates to before electricelectric moves bus aluminium alloy enclose skeleton texture field.
Background
The passenger car body framework in the market is formed by welding steel plate profiles, the whole car body is heavy, dust, harmful particles and the like are more in the product implementation process, the influence on the body of an operator is deep, in order to prolong the service life of a car, the steel car body also needs to be subjected to multi-channel anticorrosion process treatment, the front wall serves as a key part of the safety of the whole car, and the reliability of the structure plays a very critical role. The aluminum alloy material on the one hand the proportion is less, can effectively reduce the weight of whole automobile body skeleton, and secondly, the corrosion resistance of aluminium alloy itself is stronger, need not do the surface corrosion protection of material and handle, and on the other hand because the characteristic of its forming process can select according to whole car molding structure, extrudes the different preceding section bar structure of enclosing, guarantees product batch production's uniformity.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a enclose skeleton texture before electricelectric moves bus aluminum alloy solves above-mentioned problem is provided.
The technical scheme of the utility model as follows: an aluminum alloy front wall framework structure of a pure electric bus comprises a front wall upper framework, a front wall middle framework and a front wall lower framework;
the utility model discloses enclose skeleton texture before electricelectric moves bus aluminum alloy forms by aluminum alloy ex-trusions and coupling assembling, standard part combination, aluminum alloy ex-trusions form through the mould extrusion by raw and other materials aluminium ingot, the connecting piece is then formed through the mould forging, rivet mounting hole has all been seted up at corresponding position to aluminum alloy ex-trusions, connecting piece, uses the rivet to pass through the riveter will square pipe and coupling assembling connect. Firstly, the front wall framework is provided with a plurality of aluminum alloy sections with uniform specifications, different section specifications are selected according to modeling and structure, mounting hole positions are arranged at corresponding fixed positions, and the front wall framework is connected with the main body structure through connecting pieces and rivets. Secondly, each sub-assembly of the front wall framework is connected and fixed through a connecting piece and a side wall upright post through an aluminum connecting plate through bolts, so that the strength of the whole vehicle framework is enhanced, and the overall structural performance of the vehicle body framework assembly is improved. Meanwhile, traditional large-scale process tool equipment does not need to be set for the front wall framework assembly, so long as at each split charging and final assembly station, small-sized connecting equipment such as a professional riveter is installed, operability is strong, the utilization rate of a plant is effectively improved, the turnover period of logistics is shortened, and initial investment in the research and development process of new vehicle types is reduced. The utility model discloses the structure can effectively reduce the weight of enclosing the skeleton before whole car, has avoided the welding process between each part, is favorable to product modularized design and production, has improved product batch production's efficiency, has guaranteed to enclose the uniformity of assembly installation before each.
