Description

Oil storage cavity structure

Technical Field

The utility model relates to an automobile manufacturing technical field especially relates to an oil storage cavity structure.

Background

Improving the transmission efficiency of commercial vehicles is always a goal constantly pursued by the automobile industry, and has the economic benefits of reducing the vehicle cost of customers and the social benefits of saving energy and reducing carbon emission. The drive axle is used as an important component of a transmission system of the commercial vehicle, and the transmission efficiency of the drive axle directly influences the transmission efficiency of the whole commercial vehicle.

At present, the drive axle of the commercial vehicle mainly stirs oil in an oil cavity of the drive axle package by a gear, and the lubricating oil reaches a bearing and the gear through an oil duct or a direct splashing mode. In the starting and low-speed running stages of the vehicle, the splashing effect is not obvious due to the low rotating speed of the gear, and the oil liquid level in the bridge package needs to be filled to a higher position for effectively lubricating key parts such as a bearing gear and the like. When the vehicle normally runs to a high-speed stage, oil splashes violently due to high-speed operation of the gear, key parts such as bearings are sufficiently lubricated, excessive oil far meets the lubricating requirement, and meanwhile, the oil stirring power consumption is increased, the efficiency of a drive axle is reduced, and the axle produces serious side effects.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a thereby to the not enough of prior art provides an oil storage chamber structure, has solved the lubricated and low problem of transmission efficiency of prior art transaxle.

The utility model discloses an adopt following technical scheme to realize:

an oil storage cavity structure comprises a drive axle, a drive gear, an oil storage cavity, an axle packet cavity and an oil storage cavity; the oil storage cavity is provided with an oil inlet and an oil outlet, the oil storage cavity is arranged on the gear face side of the driving axle gear, and the oil inlet faces the gear; the bridge package cavity and the oil storage cavity are arranged in the drive axle.

Preferably: the oil storage cavity is provided with an oil inlet, and the oil scraping plate is arranged at an oil inlet of the oil storage cavity. Preferably: still include connection structure, the oil storage chamber side is equipped with connection structure.

Compared with the prior art, the utility model discloses following profitable technological effect has:

compared with the prior art, the utility model, effectively improve the transmission efficiency of transaxle under operating mode commonly used, reduce user's cost of using car, the energy saving reduces the carbon emission.

Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention more clearly understood, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict. In the description of the present invention, it should also be noted that, unless otherwise explicitly specified or limited, the terms "disposed," "mounted," and "connected" are to be construed broadly, e.g., as meaning fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

The first embodiment is as follows:

as shown in fig. 1-5, an oil storage cavity 1 structure comprises a drive axle, a drive gear, an oil storage cavity 1, an axle bag cavity 3 and an oil storage cavity 4; the oil storage cavity 1 is a hollow cavity thin-wall part, the oil storage cavity 1 is provided with an oil inlet 6 and an oil outlet 8, and the shape of the oil inlet 6 is not limited to a circle, a square or other shapes; the number of the oil inlets 6 and the oil outlets 8 is not limited to single or multiple, the oil storage chamber 1 is arranged on the tooth face side of the drive axle gear 2, and the oil inlets 6 face the gear; still include the frizing, 1 oil inlet 6 in oil storage chamber is equipped with frizing 7 makes fluid get into the cavity more easily, 1 side in oil storage chamber is equipped with connection structure 9 makes things convenient for oil storage chamber 1 reliably to be connected to main reducer housing 5 on, the connection form in oil storage chamber 1 is not limited to bolted connection, the riveting, splices, connection modes such as welding, bridgeware cavity 3 and oil storage chamber cavity 4 set up in the transaxle.

During operation, gear operation flies to splash and fluid attached to the gear enters into oil storage chamber 1 through oil scraping plate 7, simultaneously 1 downside in oil storage chamber is opened oil-out 8, should oil-out 8 and bridge package fluid intercommunication, fluid flows back to bridge package cavity 3 through oil-out 8 in the oil storage chamber 1.

The oil inlet quantity of an oil inlet 6 of the oil storage cavity 1 is influenced by the rotating speed of a drive axle and the size of the oil inlet 6, the higher the rotating speed of the drive axle is under the condition that the size of the oil inlet 6 is determined, the higher the oil inlet speed of the oil inlet 6 is, and the oil outlet quantity of an oil outlet 8 is mainly influenced by the size of the oil outlet 8.

When the oil inlet speed is not greater than the oil outlet speed, oil cannot be stored in the oil storage cavity 1, the liquid level in the bridge package cavity 3 cannot be changed, and the liquid level of the oil in the oil storage cavity 1 is flush with the liquid level in the bridge package cavity 3; when the oil inlet speed is higher than the oil outlet speed, oil is stored in the oil storage cavity 1, at the moment, the oil part in the bridge package cavity 3 is stored in the oil storage cavity 4, and the oil liquid level in the bridge package cavity 3 is reduced.

By assembling the structure of the oil storage cavity 1, the sizes of the oil inlet 6 and the oil outlet 8 are reasonably designed, so that the oil storage cavity 1 does not store oil when running at low speed, and the liquid level in the bridge package cavity 3 is unchanged; and oil liquid is stored when the vehicle runs at a high speed, and the liquid level in the bridge package cavity 3 is reduced. The dynamic liquid level management function of the oil storage cavity 1 can effectively improve the transmission efficiency of the drive axle.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.

The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications or substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present invention.
