Title:
DIFFERENTIAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/061409
Kind Code:
A1
Abstract:
A differential device in which extension members that are inserted through bearing members of a differential case are joined to bottomed members of output members of the differential mechanism and oil seals are interposed between the outer ends of the extension members and the transmission case. In the differential device, inner pipe sections (Pi) are provided in the bottomed members (11b) or the extension members (20) and outer pipe sections (Po) are provided in the other of the bottomed members and the extension members. Between the surfaces of the inner and outer pipe sections (Pi, Po) that are fitted together, joining members (J) and sealing members (26) are interposed. The joining members (J) are provided with a joining pipe section (Jp) that is fitted together with and fixed to one of the surfaces that are fitted together, and an elastic locking member (Jc) that is connected to one end of the joining pipe section (Jp). Recesses (30) for locking the elastic locking member are provided on the other of the surfaces that are fitted together. As a result, in addition to making it possible to secure the advantages that result from special installation of extension members in prior devices, the present invention makes it possible to precisely join the extension members to the bottomed members regardless of the material configuring the extension members, increasing the degree of freedom in selecting materials for the extension members.
