Stepped part 68 forms to radially inner side from the end of wide diameter portion 67.Forming the inwall of side gear 6 of stepped part 68 and the angle of the running shaft O of side gear 6 is 90 °.Stepped part 68 extends to the radially inner side of the portion of being pressed into 66.
Insertion part 69 forms along being pressed into direction from the end of the stepped part 68 of radially inner side, and transmission shaft 16 is inserted from opening portion 65.Form the spline tooth 69a chimeric with the spline tooth 16a that is formed at transmission shaft 16 in insertion part 69.
Gear part 62 is arranged on the periphery of the gear cylinder portion 61 that is positioned at container 13, engages with small gear 5.
The rotation that is passed to main reducing gear 2 is transmitted to side gear 6 via cover 3, differential mechanism support 4, spindle unit 14, small gear 5.The rotation that is delivered to side gear 6 via transmission shaft 16 to driving wheel transmission.
Sealed member 7 is made up of metal material, is pressed into portion 66 from opening portion 64.Sealed member 7 has dish portion 71, sealed cylindrical portion 72 and barb portion 73.In addition, describe in detail below, barb portion 73 forms in the time of indentation sealing parts 7.
Dish portion 71 mate side gear 6 opening portion 64 diameter and form, opening portion 64 is blocked.
Sealed cylindrical portion 72 extends setting from the outer periphery of dish portion 71 to being pressed into direction, is pressed into the portion of being pressed into 66.
Barb portion 73 makes the front end side distortion of sealed cylindrical portion 72 and forms in the time being pressed into, and engages with the inwall of the side gear 6 that forms wide diameter portion 67.
At this, in Fig. 3, represent to be pressed into the sealed member 7 before the portion of being pressed into 66.The sealed member 7 being pressed into before the portion of being pressed into 66 is made up of dish portion 71 and sealed cylindrical portion 72, is formed with along the tapered portion 74 that is pressed into direction hole enlargement in the front end side of sealed cylindrical portion 72.Tapered portion 74 is 45 ° as illustrated in fig. 3 with the angle beta of the inwall of the side gear 6 of formation stepped part 68.
If sealed member 7 is pressed into portion 66, the front end of sealed cylindrical portion 72 contacts with the inwall of the side gear 6 that forms stepped part 68, if and then sealed member 7 is pressed into portion 66, the front end side direction radial outside plastic deformation of sealed cylindrical portion 72, formation barb portion 73.Barb portion 73 engages with the inwall of the side gear 6 that forms wide diameter portion 67, suppresses the chimeric loosening of sealed member 7.
Effect to embodiment of the present invention describes.
There is the interior rotation of oily case of transmission 8 and along the running shaft O of side gear 6, sealed member 7 be pressed in the box of tricks 1 of side gear 6 of formation porose 63 in inclosure, by the portion that is pressed into 66 of indentation sealing parts 7, from the end that is pressed into portion 66 along being pressed into the wide diameter portion 67 of direction hole enlargement, extending the stepped part 68 of the radially inner side that is set to the portion of being pressed into 66 from the end of wide diameter portion 67, forming hole 63 from the end of stepped part 68 along the insertion part 69 that is pressed into direction extension setting.In addition, be formed on while being pressed at sealed member 7 the barb portion 73 contact with the inwall of side gear 6 that forms stepped part 68 and be out of shape and engage with the inwall of the side gear 6 of formation wide diameter portion 67.
By barb portion 73 is engaged with the inwall of the side gear 6 that forms wide diameter portion 67, even in the situation that sealed member 7 expands, shrinks due to heat, also can suppress the chimeric loosening of sealed member 7, suppress the generation (corresponding to claim 1,4,5 effect) of vibration.
In addition, the oil that can prevent from being sealing in case of transmission 8 escapes in hole 63, and prevents from case of transmission 8 leakage of oils, improves sealing.Although Sealing also can be set between transmission shaft 16 and gear cylinder portion 61, now, oil sealing can not be entered in case of transmission 8 before inserting transmission shaft 16.Therefore,, in the time of assembling, must after having assembled case of transmission 8, insert transmission shaft 16, and then oil sealing be entered in case of transmission 8 to operating efficiency variation.In the present embodiment, indentation sealing parts 7, and then barb portion 73 is engaged with the inwall of the side gear 6 that forms wide diameter portion 67, can prevent thus leakage of oil before inserting transmission shaft 16, as long as insert transmission shaft 16 after having assembled case of transmission 8, can improve operating efficiency (corresponding to claim 1,4,5 effect).
Front end side in the sealed cylindrical portion 72 that is pressed into the sealed member 7 before the portion of being pressed into 66 forms along the tapered portion 74 that is pressed into direction hole enlargement, can make thus the front end side of sealed cylindrical portion 72 easily to radial outside distortion, can easily form the effect of the 73(of barb portion corresponding to claim 2).
Above, embodiments of the present invention are illustrated, but above-mentioned mode of execution only represents a part for Application Example of the present invention, not technical scope of the present invention has been defined as to the concrete formation of above-mentioned mode of execution.
In addition, as an example, box of tricks is illustrated in the above-described embodiment, but is not limited to this, can be applicable to prevent that fluid from escaping to the seal construction in the hole of being located at a rotating body.
In the above-described embodiment, be provided with stepped part 68 to form the inwall of side teeth groove 6 of stepped part 68 and the angle of the running shaft O of side gear 6 as the mode of 90 °, but be not limited to this, also can form hole 63 with stepped part 68 along the mode that is pressed into direction hole enlargement as illustrated in fig. 4.Thus, the in the situation that of in sealed member 7 is pressed into hole 63, can make the front end side of the sealed cylindrical portion 72 contacting with the inwall of side gear 6 that forms stepped part 68 easily to radial outside distortion (corresponding to the effect of claim 3).
In the above-described embodiment, tapered portion 74 and the angle beta of the inwall of the side gear 6 of formation stepped part 68 are made as to 45 °, the inwall of the side gear 6 that forms wide diameter portion 67 is made as to 40 °~50 ° with the angle [alpha] of the inwall of the side gear 6 of formation stepped part 68, but be not limited to this, as long as the front end side that makes sealed cylindrical portion 37 in the time being pressed into easily to radial outside distortion, make the barb portion 73 of sealed member 7 and form wide diameter portion 67 side gear 6 inwall engaging and obtain the effect of present embodiment.
