Abstract
Commercial vehicle's transaxle, including axle housing, main reducer, be provided with an installation cavity on the axle housing, one side of installation cavity is provided with the back lid, the opposite side is provided with the opening relative with the back lid, and main reducer is including fixing at opening edge and closing cap open-ended reduction gear bracket, driving gear, driven gear, and driving gear and driven gear all are provided with an oil shield through the rotatable cooperation of bearing and reduction gear bracket between driven gear edge and back lid. The utility model discloses set up the oil removal cover between driven gear and back lid, when the vehicle high speed in-process of traveling, the inboard lubricating oil of oil removal cover can be because driven gear rotates produced centrifugal force at a high speed, enter into between oil removal cover and the back lid, that is to say, the inboard lubricating oil liquid level step-down of oil removal cover, thereby the resistance that lubricating oil produced to driven gear has been reduced, when driven gear's rotational speed step-down, the inside lubricating oil position of oil removal cover risees, in order to carry out sufficient lubrication to driven gear.
Description
Technical Field
The utility model relates to the technical field of vehicles, concretely relates to commercial vehicle's transaxle.
Background
Commercial vehicle's transaxle generally includes the axle housing, main reducer, it has the open-ended installation cavity to be provided with the side at the middle part of axle housing, main reducer includes the reduction gear bracket, the driving gear, driven gear, wherein the opening part at the axle housing installation cavity is fixed to the reduction gear bracket, become an inclosed cavity with the installation cavity closing cap, the driving gear all passes through the rotatable cooperation of bearing and reduction gear bracket with driven, in order to carry out sufficient lubrication to main reducer, need pack more lubricating oil in the installation cavity, and thus, though can reach the lubricated effect of preferred, but more lubricating oil also can lead to power loss more simultaneously, especially driven gear is when rotating, its resistance that need overcome and come from lubricating oil, cause power loss, then, the transmission efficiency who leads to main reducer is lower.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a commercial vehicle's transaxle, it can reduce power loss under the prerequisite that does not influence lubrication, improves transmission efficiency to prior art not enough.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
commercial vehicle's transaxle, including axle housing, main reducer, be provided with an installation cavity on the axle housing, one side of installation cavity is provided with the back lid, the opposite side is provided with the opening relative with the back lid, and main reducer is including fixing at opening edge and closing cap open-ended reduction gear bracket, driving gear, driven gear, and driving gear and driven gear all are provided with an oil shield through the rotatable cooperation of bearing and reduction gear bracket between driven gear edge and back lid.
Two bearing covers are further arranged in the mounting cavity, the two bearing covers are respectively and fixedly connected to two sides of the speed reducer bracket, and two sides of the oil separation cover are respectively fixed on the two bearing covers.
The two sides of the oil separation cover are respectively provided with outward extending flanging parts, the two flanging parts are respectively arranged on the outer sides of the two bearing covers in an overlapping mode, and the flanging parts are fixed on the bearing covers through bolts.
The beneficial effects of the utility model reside in that:
the utility model discloses set up the oil removal cover between driven gear and back lid, when the vehicle high speed in-process of traveling, the inboard lubricating oil of oil removal cover can be because driven gear rotates produced centrifugal force at a high speed, enter into between oil removal cover and the back lid, that is to say, the inboard lubricating oil liquid level step-down of oil removal cover, thereby the resistance that lubricating oil produced to driven gear has been reduced, when driven gear's rotational speed step-down, the inside lubricating oil position of oil removal cover risees, in order to carry out sufficient lubrication to driven gear.
Drawings
Fig. 1 is a schematic structural view of the present invention;
fig. 2 is an installation schematic diagram of the present invention.
Detailed Description
The invention will be further described with reference to the accompanying drawings and specific embodiments:
as shown in fig. 1 and 2, in order to provide a driving axle of a commercial vehicle of the present invention, which includes an axle housing 10 and a main reducer, a mounting cavity 11 is provided at a middle portion of the axle housing 10, a rear cover 12 is provided at one side of the mounting cavity 11, an opening opposite to the rear cover 12 is provided at the other side of the mounting cavity 11, the main reducer includes a reducer bracket 20, a driving gear 41, and a driven gear 42, wherein an edge of the reducer bracket 20 is fixedly connected to an edge of the opening of the axle housing 10, i.e., the reducer bracket 20 covers the opening of the axle housing 10, i.e., the mounting cavity 11 is enclosed by the reducer bracket 20 and the middle portion of the axle housing 10, the driving gear 41 and the driven gear 42 are rotatably mounted on the reducer bracket 20 through bearings and are engaged with each other to transmit power, an oil-proof cover 30 is provided between the edge of the driven gear 42 and, that is, the oil separation cover 30 separates a space between the driven gear 42 and the rear cover 12 into two portions which communicate only at the edge of the oil separation cover 30.
The utility model discloses set up the oil removal cover between driven gear and back lid, when the vehicle high speed in-process of traveling, the inboard lubricating oil of oil removal cover can be because driven gear rotates produced centrifugal force at a high speed, enter into between oil removal cover and the back lid, that is to say, the inboard lubricating oil liquid level step-down of oil removal cover, thereby the resistance that lubricating oil produced to driven gear has been reduced, when driven gear's rotational speed step-down, the inside lubricating oil position of oil removal cover risees, in order to carry out sufficient lubrication to driven gear.
The utility model discloses still be provided with two bearing caps 21 in foretell installation cavity 11, these two bearing caps 21 pass through bolt difference fixed connection in reduction gear bracket 20's both sides, and the both sides of oil removal cover 30 are respectively through the bolt fastening on two bearing caps 21, and of course, oil removal cover 30 also can be the snap-on reduction gear bracket 20, and in a word, can be between oil removal cover 30 and back lid 12 and all form the clearance between oil removal cover 30 and driven gear 42's the edge can.
On the basis of the above scheme, in order to facilitate the fixing of the oil separation cover 30, the two sides of the oil separation cover are respectively provided with the flanging parts 31 which extend outwards, the two flanging parts 31 are respectively erected at the outer sides of the two bearing covers 21, the flanging parts 21 are fixed on the bearing covers 21 through bolts, and the oil separation cover 30 is of a roughly semicircular structure and comprises an arc-shaped section in the middle and the flanging parts 31 at the two sides in the cross sectional shape.
The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still make modifications to the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some technical features, and these modifications or substitutions do not make the essence of the corresponding technical solutions depart from the spirit and scope of the technical solutions of the embodiments of the present invention.
