Abstract
The invention relates to a design method for a highway passenger car three-section overlap butt carframe. The design method for the highway passenger car three-section overlap butt carframe is characterized by comprising a front section carframe module, a middle truss module and a back section carframe module. Two side front section carframe longitudinal beams in the front section carframe module are in a [-shaped structure, two side back section carframe longitudinal beams in the back section carframe module are in a [-shaped structure, and the middle truss module is welded into a framework structure by rectangular tubes. The design method for the highway passenger car three-section overlap butt carframe meets the demands on reasonable layout of all systems of an underpan, can conveniently achieve the systematization and the modularization design of the underpan, and simultaneously meets the demand of luggage compartment size, manufacture cost of all sections of the carframe is greatly reduced, the weight of the carframe is greatly decreased, and simultaneously completely knocked down (CKD) different place transportation and assembly of a underpan carframe can conveniently achieved.
Description
Technical field
The present invention relates to the method for designing of three sections overlap joint vehicle frames of a kind of highway passenger vehicle.
Background technology
What the domestic demand amount was larger now is the highway passenger vehicle of 8.5m and two kinds of length sections of 8.9m.The passenger vehicle of these two length sections is mainly to run at short-distance transportation inside the province, tourism and group's regular bus, and the 8.5m passenger vehicle all has wide market outlook at short-distance transportation inside the province, tourism and group's regular bus.In order to satisfy the technical requirements of 8.5 meters highway passenger vehicle chassis specials, realizing the reasonable Arrangement requirement of each system of chassis, and be convenient to strange land transportation and assembling that chassis frame is realized CKD.Need to adopt modular design to frame assembly.
Summary of the invention
What the domestic demand amount was larger now is the highway passenger vehicle of 8.5m and two kinds of length sections of 8.9m.The passenger vehicle of these two length sections is mainly to run at short-distance transportation inside the province, tourism and group's regular bus, and the 8.5m passenger vehicle all has wide market outlook at short-distance transportation inside the province, tourism and group's regular bus.In order to satisfy the technical requirements of 8.5 meters highway passenger vehicle chassis specials, realizing the reasonable Arrangement requirement of each system of chassis, and be convenient to strange land transportation and assembling that chassis frame is realized CKD.Need to adopt modular design to frame assembly.
