Description
The present invention relates to a vehicle differential device, and more particularly to lubrication around a bearing that supports a differential case.
In this type of differential device, there is a case where the lubricating oil filled in the housing is supplied to each sliding portion such as a bearing by being lifted up by a diff ring gear fixed to the outer wall of the differential case. For example, Patent Document 1 proposes that a bearing receiving recess is formed with an oil receiving rib for receiving the lubricating oil scattered by the rotation of the diff ring gear, and a guide rib for guiding the lubricating oil received by the oil receiving rib to the bearing. Has been.
By the way, when adopting a structure in which the lubricating oil scattered by the diff ring gear is received and guided to the bearing as in the conventional device, there is a problem that the mechanical loss of the diff ring gear due to agitation resistance increases.
Therefore, in order to reduce the stirring resistance by the lubricating oil, it is conceivable to arrange a separate plate in the differential case. However, when the separate plate is simply disposed, the amount of the lubricating oil scattered on the oil receiving rib is likely to decrease, and in some cases, the lubricity may be lowered.
The present invention has been made in view of the above-described conventional situation, and an object of the present invention is to provide a vehicle differential apparatus that can reduce agitation resistance due to lubricating oil and can secure the amount of lubricating oil to the bearing.

In the vehicle differential device, a rib extending so as to face the rotation direction of the differential case is formed in a portion of the housing facing the other side in the axial direction of the differential case, and the differential ring gear is disposed in the housing by a separate plate. It is divided into a side chamber and the other side chamber in which the rib is formed, and an oil reservoir portion is formed by the separate plate and the rib to store a part of the lubricating oil swept up by the diff ring gear. A communication path for supplying at least lubricating oil to the bearing is provided.
According to the differential device of the present invention, the inside of the housing is divided into the one side chamber in which the diffring gear is arranged by the separate plate and the other side chamber, so that a part of the lubricating oil in the one side chamber swept up by the diffring gear is another As a result, the amount of lubricating oil in one side chamber can be reduced, and the stirring resistance can be reduced.
In the present invention, the oil reservoir portion for storing a part of the lubricating oil is formed by the rib formed on the housing and the separate plate, and the lubricating oil in the oil reservoir portion is supplied to the bearing. Lubricating oil can be stored, and the required amount of lubricating oil to be supplied to the bearing can be ensured as compared with the case where the conventional scattered lubricating oil is received and supplied to the bearing as it is.
Further, since the oil reservoir is formed by the rib for increasing the rigidity of the housing and the separate plate for reducing the stirring resistance, the lubricity can be improved without adding any special parts.

A part of the obtained lubricating oil flows into the right chamber B. As a result, the agitation resistance received by the diff ring gear 7a can be reduced by the amount that the amount of lubricating oil in the left chamber A decreases.
In the present embodiment, the rib 27e and the outer wall 27a 'of the differential housing portion 27 and the separate plate 35 form an oil reservoir portion 37 for storing lubricating oil, and the lubricating oil in the oil reservoir portion 37 is passed through the communication path 38. Since the lubricating oil pumped up by the diff ring gear 7a is temporarily stored in the oil reservoir 37, the lubricating oil scattered to the bearing 32 is compared with the conventional case where the scattered lubricating oil is supplied to the bearing as it is. The required amount of lubricating oil for supply can be ensured.
Further, since the oil reservoir portion 37 is formed by the rib 27e for increasing the rigidity of the differential housing portion 27 and the separation plate 35 for reducing the stirring resistance, the lubricity can be improved without adding special parts. Can be planned.
In the above embodiment, the rib 27e extends in the direction orthogonal to the rotation direction of the differential case 26, in other words, in the mold splitting direction of the housing body 27a, so that the oil reservoir 37 is formed without complicating the casting operation. can do.
Note that the ribs 27e are not necessarily orthogonal to the rotation direction. In short, the ribs 27e may be opposed to the rotation direction, for example, may be crossed obliquely.
