Background technology
The continual mileage of current electronlmobil is shorter, and electrically-charging equipment is perfect not enough, and electronlmobil can only as the vehicle of short distance.To long-distance long journey or the longer mileage of continuous traveling, gasoline car more for convenience.
Because battery-driven car market is also unstable ripe, if it is high to develop special electromobile frame input cost, have a big risk.If make battery-driven car into after removing the assemblies such as driving engine with existing fuel vehicle, retrofit process not only bothers, and also reduces the performance of former vehicle frame to a certain extent, also causes larger hidden danger at secure context.The deficiency of obvious interchangeability aspect is there is between visible traditional fuel vehicle vehicle frame and pure electric automobile vehicle frame.Therefore, exploitation Dual-energy source general utility functions vehicle frame well can take into account gasoline car or electronlmobil parts are arranged and installed, improve the alerting ability of vehicle production, greatly reduce enterprise and design and develop cost and mould development expense, also well meet the demand of client to gasoline car or pure electric automobile simultaneously.
Summary of the invention
Object of the present invention is just to provide one according to the different demand of client, can produce gasoline car or electronlmobil with same vehicle frame.And without the need to making any change to vehicle frame, overcome the deficiency of traditional vehicle frame dynamic assembly interchangeability aspect.Namely remain the advantage of conventional gasoline car, meet again the Dual-energy source general utility functions vehicle frame of portions of client to the demand of pure electric automobile.
Solution of the present invention is such:
A kind of Dual-energy source general utility functions vehicle frame, comprises the vehicle frame connected into by left and right longeron, front cross rail and after cross member, it is characterized in that: described longeron is bent, form low early and high after two attachment faces; Mount pad is fixed with at the longeron of front attachment face, connection structure of living is adopted to be fixed with change speed gear box mount pad and power battery pack assembly mount pad at rear attachment face after cross member foremost, the installation support installed change speed gear box or install battery assembly is formed, for installing change speed gear box or installing battery assembly between longeron bending place and the support of front attachment face.
Technical scheme also comprises more specifically: described change speed gear box mount pad is positioned at the middle part of crossbeam foremost, and described power battery pack assembly mount pad adopts two, lays respectively at the both sides of change speed gear box mount pad.
Further: the connection structure alive of described fixing change speed gear box mount pad is structure with bolts, is fixed by change speed gear box mount pad with bolt.
Further: the connection structure alive of described stationary power battery pack assembly mount pad is structure with bolts, is fixed by power battery pack assembly mount pad with bolt.
Further: described longeron is bent to square.
Further: the mount pad that left and right longeron is fixed is symmetrical installation.
Advantage of the present invention is that chassis side rail central space and set mount pad can the installations of compatible gasoline vehicle engine and transmission assembly or electric automobile power battery group assembly well, vehicle frame rear portion can according to gasoline car or the different back axle required of electronlmobil choosing dress, the exchange that any change can realize between gasoline car and pure electric automobile need not be carried out to vehicle frame, improve the alerting ability of vehicle production, greatly reduce enterprise and design and develop cost and mould development expense, also well meet the demand of client to gasoline car or pure electric automobile simultaneously.
