Background

Fork trucks are industrial handling vehicles, and refer to various wheeled handling vehicles that perform handling, stacking, and short-distance transport operations on piece pallet goods. The International organization for standardization ISO/TC110 is referred to as an industrial vehicle. It is commonly used for transportation of large warehouse goods, and is usually driven by an oil-burning engine or a battery. The heavy forklift adopts a diesel engine as power, has the bearing capacity of 10.0-52.0 tons, and is generally used for outdoor operation in industries such as wharfs and steel with heavy goods. The processing of the drive axle of the heavy forklift usually needs a lathe combined with a boring machine tool, the cost for purchasing numerical control boring machine tools is too high, the cost is too high for small factories, particularly for small factories producing the heavy forklift, and the annual output of the small factories in one year basically does not exceed two digits. Meanwhile, the axle package (namely the drive axle middle axle housing) of the front drive axle housing of the heavy forklift is large in body and high in casting cost. However, large trucks need to be scrapped and treated by the service life and similar iron scraps, but many parts of large trucks far reach the abandonment degree, so that a great deal of waste is caused. Therefore, how to effectively reduce the cost and improve the production profit when the front drive axle of the heavy forklift is produced is a problem to be solved urgently.

Furthermore, the reduction gear includes gear wheel, pinion and second drive shaft, rotationally installs gear wheel and pinion in the reduction gear mount pad and gear wheel cover establish be fixed in with scrap large-scale automobile rear drive axle's spiral bevel gear assembly's drive shaft on, gear wheel and pinion mesh mutually, the fixed cover of pinion is located on the second drive shaft and the free end of second drive shaft is worn out the reduction gear mount pad and is connected with heavy fork truck's engine output shaft.

The utility model provides a front drive axle for heavy fork truck, including scrapping the complete rear drive axle of large automobile, reduction gear mount pad and reduction gear, reduction gear mount pad installation one side is equipped with the second ring flange with the well drive axle housing ring flange looks adaptation of large-scale scrapped automobile rear drive axle, it is used for linking up with heavy fork truck engine output shaft to be equipped with the third ring flange on the one side of processing second ring flange is kept away from to the reduction gear mount pad, the reduction gear is installed in the reduction gear mount pad and the output shaft of reduction gear and the drive shaft coaxial coupling of scrapping the spiral bevel gear assembly of large automobile rear drive axle, the input shaft and the heavy fork truck engine output shaft coaxial coupling of reduction gear.

Furthermore, the reduction gear includes gear wheel, pinion and second drive shaft, rotationally installs gear wheel and pinion in the reduction gear mount pad and gear wheel cover establish be fixed in with scrap large-scale automobile rear drive axle's spiral bevel gear assembly's drive shaft on, gear wheel and pinion mesh mutually, the fixed cover of pinion is located on the second drive shaft and the free end of second drive shaft is worn out the reduction gear mount pad and is connected with heavy fork truck's engine output shaft.

Furthermore, the gear ratio of the large gear to the small gear is 3-8: 1-2.

By adopting the technical scheme, the invention has the beneficial effects that: the whole rear drive axle of the scrapped large automobile can completely meet the driving speed low-speed carrying speed of the front drive axle of the heavy forklift truck by combining the speed reducer, so that the front drive axle of the heavy forklift truck is reformed and applied to the front drive axle of the heavy forklift truck by reforming the scrapped large automobile rear drive axle shell of the large automobile into a durable rear drive axle, the scrapped large automobile can completely finish the scrapping degree when the large automobile is scrapped, and the partial components of the scrapped large automobile can be realized by reforming the scrapped large automobile rear drive axle into the front drive axle of the heavy forklift truck The front drive axle of the heavy forklift is not required to be cast again, and compared with the existing front drive axle of the heavy forklift, the cost can be saved by more than 60%, the production cost is greatly reduced, and the front drive axle of the heavy forklift can be widely popularized and applied.
