AI Technical Summary
Existing technologies cannot effectively lubricate the drive axle through shaft bearings, leading to frequent burn-out failures due to poor lubrication.
Design a lubricating oil collection cover that uses an oil collection groove, an oil guide groove and an oil outlet hole to collect and guide gear oil to the through shaft bearing for continuous lubrication. The rotation of the gear drives the lubricating oil to flow from bottom to top into the bearing cavity.
This achieves continuous and effective lubrication of the through shaft bearing, reduces lubricating oil churning losses, and improves the transmission efficiency of the drive axle.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of drive axles, in particular to a drive axle lubricating oil collecting cover. The oil collecting cover can concentrate and guide the drive axle lubricating oil and continuously and effectively lubricate the through-shaft bearing. Background Art
[0002] Lubricating oil has the functions of lubrication, cleaning, heat dissipation, and rust prevention. At present, the drive axle mostly uses two lubrication methods, gear splash lubrication or gear pump active lubrication, to lubricate the gear pair and bearings in the drive axle cavity; when the vehicle is running at a low speed for a long time, the through-shaft bearing is located upward, and the above two lubrication methods cannot effectively lubricate it, resulting in poor lubrication and frequent ablation failures of the through-shaft bearing. Utility Model Content
[0003] The purpose of the utility model is to overcome the deficiencies of the above-mentioned prior art and to provide a lubricating oil collecting hood, by means of which the gear oil can be concentrated, guided and flowed into the through-shaft bearing cavity under the rotation of the gear to continuously and effectively lubricate the bearing, thereby solving the frequent burning faults caused by poor lubrication of the through-shaft bearing of the drive axle.
[0004] The technical solution provided by the utility model is: a lubricating oil collecting hood, comprising a lubricating oil collecting hood body, which is special in that an oil collecting groove is arranged at the lower end of the lubricating oil collecting hood body, and the opening of the oil collecting groove is communicated with the lubricating oil in the driving axle cavity; an oil guide groove is arranged in the middle position of the lubricating oil collecting hood body, and the oil guide groove is wrapped around the outer side of the gear; an oil outlet hole is arranged above the lubricating oil collecting hood body, the oil outlet hole is hollow, and the oil outlet hole extends into the through-shaft bearing cavity; the oil collecting groove, the oil guide groove and the oil outlet hole are communicated; and a plurality of mounting holes are arranged on both sides of the lubricating oil collecting hood body.
[0005] Furthermore, the oil guide groove is wrapped around the outside of the gear on three sides, and a gap is left along the gear profile.
[0006] Furthermore, the oil outlet hole is tubular.
[0007] The beneficial effects of the utility model are as follows: 1. By utilizing the oil collecting cover, the gear oil can be concentrated, guided, and flowed out into the through-shaft bearing cavity under the rotation of the gear to continuously and effectively lubricate the bearing, thereby solving the problem of poor lubrication and ablation of the through-shaft bearing; 2. The agitation of the lubricating oil in the drive axle cavity is reduced, the kinetic energy loss of the oil agitation is reduced, and the transmission efficiency of the entire axle is improved.

[0013] In order to better understand and implement the present invention, the present invention is described in detail below with reference to the accompanying drawings.
[0014] like Figure 1 , 2 As shown in Figures 3 and 4, a lubricating oil collecting hood comprises a lubricating oil collecting hood body, an oil collecting groove 1 is provided at the lower end of the lubricating oil collecting hood body, the oil collecting groove 1 is open, the oil collecting groove 1 is located below the lubricating oil surface in the driving axle cavity and is connected with the lubricating oil in the driving axle cavity; an oil guide groove 2 is provided in the middle part of the lubricating oil collecting hood body, which is wrapped around the outer side of the gear 7 on three sides, and a certain gap is left along the contour of the gear 7 to prevent mutual wear; an oil outlet hole 3 is provided above the lubricating oil collecting hood body, the oil outlet hole 3 is in the shape of a special-shaped tube, the oil outlet hole 3 is hollow, the oil outlet hole 3 extends into the through-shaft bearing cavity, a bearing 6 is arranged in the through-shaft bearing cavity, and the bearing 6 supports and positions the through-shaft 5; the oil collecting groove 1, the oil guide groove 2 and the oil outlet hole 3 are connected, the lubricating oil is collected and flows in through the oil collecting groove 1, guided by the oil guide groove 2 and flows out through the oil outlet hole 3; a plurality of mounting holes 4 are provided on both sides of the lubricating oil collecting hood body, and the lubricating oil collecting hood and the reducer housing are fixed as a whole by bolts.
[0015] The utility model provides a lubricating oil collecting hood. When the vehicle is running, the lubricating oil collecting hood and the reducer housing are solidified into one and relatively still. The gear 7 rotates counterclockwise in the lubricating oil collecting hood, and a local negative pressure is formed between the tooth surface of the gear 7 and the inner wall of the lubricating oil collecting hood, thereby driving the lubricating oil in the lubricating oil collecting hood from bottom to top through the oil guide groove 2 and the oil outlet 3 to be injected into the through-shaft bearing cavity, so as to achieve the purpose of continuously lubricating and dissipating the through-shaft bearing 6.
[0016] It should be understood that the technical features not elaborated in this specification belong to the prior art. Although the implementation methods of the utility model patent are described above in conjunction with the drawings, the utility model is not limited to the above specific implementation methods, which are only illustrative and not restrictive. Ordinary technicians in this field can make more forms under the enlightenment of the utility model without departing from the scope of protection of the purpose of the utility model and the claims, which are all within the protection scope of the utility model.
