Embodiment 1

[0032] An integrated main reducer assembly with oil throwing blades (see figure 1 ), including the integral housing 1, the final drive 2 located in the integral housing 1, the inter-axle differential 3 and the inter-wheel differential 4 located outside the integral housing, the inter-wheel differential 4 includes differential The differential case 401, the differential located in the differential case 401, the differential case 401 includes a differential left case 4011, a differential right case 4012, a differential left case 4011, a differential The right shells 4012 are connected together by bolts 4013 . The differential case 401 is also connected with an oil throwing blade 5, and the oil throwing blade 5 is formed by vertically connecting the A end face 501 and the B end face 502 to form an approximate 7-shaped structure (see Figure 2-Figure 4 ), the A end surface 501 of the oil throwing blade is attached to the end surface of the right differential case 4012, and the A ...

Abstract

The invention discloses an integrated main speed reducer assembly with an oil throwing blade and relates to a main speed reducer assembly. The integrated main speed reducer assembly comprises an integrated shell, a main speed reducer, an interaxial differential and an inter-wheel differential; the inter-wheel differential comprises a differential shell and a differential, and the differential shell is also connected with the oil throwing blade; the oil throwing blade is of an approximately 7-shaped structure formed by vertically connecting an end surface A and an end surface B, the end surface A of the oil throwing blade is jointed with the end surface of the differential shell, and a connecting hole connected with the differential shell is formed in the end surface A; and the end surface B is jointed with the excircle surface of the differential shell, and the part where the end surface B is jointed with the excircle surface of the differential shell outwards warps to form an edge for scraping and throwing oil. By using the integrated main speed reducer assembly, a rear half axle gear bearing and a tandem axle bearing are sufficiently lubricated, bearing faults such as early wear and ablation as well as tandem axle breakage, tooth beating and tooth jumping can be avoided, and the aims of reducing noise and faults and prolonging the service life are achieved; and the integrated main speed reducer assembly is simple in structure, low in cost and easy to popularize and use.

Description

technical field [0001] The invention relates to a main reducer assembly, in particular to an integrated main reducer assembly with oil throwing blades. Background technique [0002] Heavy-duty truck traction has a small speed ratio and a large gear offset. When the vehicle is running, the differential case rotates, and the lubricating oil driven by it is far away from the rear half-shaft gear bearing and through-shaft bearing due to the large offset distance. Gear bearings and through-shaft bearings cannot be adequately lubricated. Especially at low speeds and when going uphill, the above phenomenon is more obvious. Poor lubrication of vehicles is likely to cause the following failures: 1. Poor lubrication of the through-shaft bearings, resulting in early wear and even ablation of the bearings; 2. Breakage of the through-shaft due to poor lubrication; A series of failures such as jumping teeth. Contents of the invention [0003] The technical problem to be solved by th...
