Problems solved by technology
Most of the existing axle housings are cast in one piece. The inner surface of the cast axle housing is smooth. The shell wall is thicker and the weight is heavy. In addition, casting defects such as shrinkage porosity and pores are easy to appear at the wall thickness during casting. , reduce the strength of the axle housing, and the axle housing often cracks and breaks at casting defects during use, causing safety accidents
The existing axle housings are all connected by welding, which makes the stability decrease with time. At the same time, the manufacturing thickness of the general axle housings is not thick, and various damages will occur after long-term use. For this reason, we A one-piece axle housing forged by intermediate frequency heating is proposed

Embodiment Construction
[0012] Any feature disclosed in this specification, unless specifically stated, can be replaced by other alternative features that are equivalent or have similar purposes. That is, unless expressly stated otherwise, each feature is one example only of a series of equivalent or similar features.
[0013] Such as figure 1 The one-piece axle housing shown is forged by intermediate frequency heating, including a half shaft casing 1, a flange 2, a reinforcement plate 3, a leaf spring seat 4, a housing 5, a reinforcement rib 6 and a steel plate bracket 7, the housing The inner wall of the top and the bottom of the body 5 is symmetrically fixed with reinforcing ribs 6, and both ends of the housing 5 are symmetrically fixed with steel plate support 7, and one end of the reinforcing rib 6 is fixedly connected with the steel plate support 7, and the steel plate support 7 is far away from the side of the housing 5. One end is fixed with a reinforcement plate 3, and the side of the reinf...

The invention discloses an integrated axle housing forged by means of medium-frequency heating. The integrated axle housing is simple in structure, low in cost and high in stability and safety and includes axle shaft sleeves, flanges, reinforcing boards, a steel board spring base, a housing body, reinforcing ribs and steel plate supports. The reinforcing ribs are symmetrically fixed to the inner walls of the bottom and top of the housing body, the steel plate supports are symmetrically fixed to the two ends of the housing body, one end of each reinforcing rib is fixedly connected to the corresponding steel plate support, the end, away from the housing body, of each steel plate support is fixedly provided with the corresponding reinforcing board, and each axle shaft sleeve is arranged on the side, away from the corresponding steel plate support, of the corresponding reinforcing board and fixedly connected to the corresponding reinforcing board through the corresponding flange. The housing body is integrally connected with the axle shaft sleeves and is higher than the steel plate supports. According to the integrated axle housing forged by means of medium-frequency heating, through an integrated structure, connection among objects is tighter, the stability is better, the durability is improved, the cost for replacing the objects is reduced, and the working efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of axle housings, in particular to an integrated axle housing forged by intermediate frequency heating. Background technique [0002] The axle housing is the basic part for installing the main reducer, differential, half shaft, wheel hub and suspension. Its main function is to support and protect the main reducer, differential and half shaft. At the same time, the axle housing is one of the main components of the driving system. The drive axle housing should have sufficient strength and rigidity, low mass, and facilitate the disassembly and adjustment of the main reducer. Most of the existing axle housings are cast in one piece. The inner surface of the cast axle housing is smooth. The shell wall is thicker and the weight is heavy. In addition, casting defects such as shrinkage porosity and pores are easy to appear at the wall thickness during casting. , Reduce the strength of the axle housing, and the axl...
