Wet axle box integrated drive axle for forklift

Abstract

The invention discloses a wet axle box integrated drive axle for a forklift. The wet axle box integrated drive axle comprises an axle housing, an input assembly, two service brake assemblies, two coaxially-distributed half shafts and two hub assemblies; the axle housing comprises a first housing body and two second housing bodies which are fixedly connected, wherein the two second housing bodies are located on the left side and the right side of the first housing body correspondingly, the service brake assemblies are located in the second housings and arranged on the half shafts in a sleevingmode, the hub assemblies are installed at the outer ends of the second housings and fixedly connected with the outer ends of the half shafts, the input assembly is installed on the first housing, andthe input assembly comprises an input shaft and an output shaft which are transversely arranged, so that the structure of the drive axle housing is reasonable, and the size is reduced, and the occupied space of the drive axle is reduced.

Description

technical field [0001] The invention relates to the technical field of construction machinery transmission, in particular to a wet-type axle box integrated drive axle for forklifts. Background technique [0002] As we all know, the operating conditions of construction machinery are relatively harsh. At present, the domestic construction machinery axle product market is still dominated by dry brake drive axles. For example, the Chinese patent document with the publication number CN202272694U discloses a dry brake axle. Dynamic internal combustion counterbalance series forklift. CN203496676U discloses an integrated transmission device for an axle box for an electric forklift, including an axle housing, a transmission, a drive axle and an axle arm assembly. CN204567140U discloses an axle-box integrated speed reduction transmission device on engineering machinery such as electric forklifts and trucks, including left drive axle housing, right drive axle housing, primary decelera...

AI Technical Summary

Problems solved by technology

[0005] 1) At present, the power input of the wet brake drive axle is the engine through the gearbox and then input to the drive axle by the transmission shaft. There is no wet axle box integrated drive axle for the motor or hydraulic motor as the power source;

[0006] 2) The dry brake drive axle adopts an external dry brake, which causes the dry brake drive axle to be greatly affected by environmental factors such as humidity, freezing, sand and dust, resulting in unstable braking performance and short service life
