Design of driving axle of heavy truck
ABSTRACT
Drive axles as one of its four Assembly vehicles, which have a direct impact on the performance of vehicle performance, and load goods vehicles is very important. When using the high power output of the engine torque to meet current fast and heavy-truck when the need for efficient, cost effective, must be used with an efficient, reliable drive axle. Design structure is simple, reliable, low cost drive axle, can greatly reduce the total cost of vehicle production, promote the economic development of the automobile.
This design first expositions has driven axles of overall structure, in analysis has at home and abroad status, and driven axles the part structure form and past form of advantages and disadvantages of Foundation Shang, determine has overall design programme: used overall type driven axles, main reducer of deceleration type type used double level reducer, main reducer gear used spiral cone gear, differential used General symmetric type cone planet gear differential, half axis used full floating type, axles shell used casting overall type axles shell. In this design, the major completed a two-stage reducer, planetary gear differential, full floating axle with tapered design and check of axle of selection of materials and so on.
