Front steering drive axle assembly

Abstract

The invention discloses a front steering drive axle assembly which comprises an axle housing (1), hubs (7), a main speed reducer belt differential assembly and wheel rim speed reducers, wherein the axle housing is provided with a balance pin hole (21) connected with a vehicle chassis; the two hubs are connected to the left end and the right end of the axle housing by hub steering structures (3); the middle part of the axle housing is provided with a cavity; the main speed reducer belt differential assembly is arranged inside the cavity; each of the two sides of the main speed reducer belt differential assembly is connected with a driving shaft (6) in a rotating mode; the driving shafts are rotatably connected with the wheel rim speed reducers on the two ends of the axle housing; the axle housing is provided with a wheel steering drive device (4); the wheel steering drive device is respectively connected with the hub steering structures of the two hubs; the section of the axle housing is in a cavity structure in a square shape; the edge of a planet wheel axle (15) is provided with a small hole (30); a wheel rim speed reducer (11) is correspondingly provided with a sinking slot (31); an anti-shifting ball (19) is installed between the hole and the slot; and the outmost side of the wheel rim speed reducer shell is provided with an end cover (20).

Description

Technical field [0001] The invention relates to a front steering drive axle assembly. Background technique [0002] With the continuous advancement of national urbanization and infrastructure construction, the production and sales of construction machinery and agricultural machinery have been significantly promoted, especially the production and sales of large-tonnage backhoe loaders and large tractors. At the same time, the technical level and manufacturing technology of construction machinery, tractors and other agricultural machinery have made considerable progress, and models with four-wheel drive are becoming more and more common. At the same time, higher requirements are put forward for the quality requirements of the whole machine. [0003] The working environment of construction machinery and agricultural machinery is harsh, and there are high requirements for the reliability and passability of the whole machine. Four-wheel drive models have become a trend. [0004] The cu...

AI Technical Summary

Problems solved by technology

[0004] The currently used axles have a large dead weight and low carrying capacity, and due to the uncompact structure, there will be oil leakage at the wheel side reducer or damage to the wheel side planetary gears, which will affect the mechanical quality.
