Housing 100 according to the retarder 1000 of the embodiment of the present invention can comprise: enclosure body 10 and isolation mounting 20.As shown in Figure 4, in enclosure body 10, there is cavity, and enclosure body 10 offers the output shaft hole 11 from the front portion of enclosure body 10 to the rear portion of enclosure body 10, intermediate shaft hole 12 and the input shaft bore 13 that are arranged in order setting from.
According to one embodiment of present invention, enclosure body 10 can comprise: the first housing 14 and the second housing, and the first housing 14 and the second housing relatively fasten and arrange to form enclosure body 10.Enclosure body 10 part shown in Fig. 4 is that the structure of the first housing 14, second housing can be substantially identical with the structure of the first housing 14, and the first housing 14 and the second housing can be arranged about both fastening line place plane symmetry.It should be noted that, the first housing 14 and the second housing are provided with output shaft hole 11, intermediate shaft hole 12 and input shaft bore 13, thus input shaft 200, jack shaft 300 and output shaft 400 can be made to be arranged on rotationally in enclosure body 10.
In addition, it should be noted that, in order to ensure the good working state of input shaft 200, jack shaft 300 and output shaft 400, lubricant oil is stored in cavity in enclosure body 10, lubricant oil can oilgear preferably, extend the working life of each gear on input shaft 200, jack shaft 300 and output shaft 400, the working life of prolonged deceleration device 1000.
Isolation mounting 20 is arranged on the below of intermediate shaft hole 12 and/or input shaft bore 13 with formative dynamics oil storage region 21 in cavity.Be understandable that, isolation mounting 20 can be arranged on the below of intermediate shaft hole 12, or isolation mounting 20 can be arranged on the below of input shaft bore 13, or isolation mounting 20 can be arranged on the below of input shaft bore 13 and intermediate shaft hole 12 simultaneously.Dynamic oil storage region 21 has circulation oil inlet end 22 and circulation oil outlet end 23, circulation oil inlet end 22 is communicated with cavity inside respectively with circulation oil outlet end 23, as shown in Figure 4, and circulation oil inlet end 22 is positioned at the top of circulation oil outlet end 23, at least part of region being positioned at the front side of isolation mounting 20 of its hollow cavity is static oil storage region 30.
Wherein, alternatively, the upper end of isolation mounting 20 can be opened wide to form circulation oil inlet end 22, thus the lubricant oil being positioned at static oil storage region 30 can be splashed to circulation oil inlet end 22 place under the effect of the gear of output shaft 400, and enters dynamic oil storage region 21.
According to one embodiment of present invention, isolation mounting 20 can comprise: many isolating plates of arranging from front to back, each isolating plate upwards extends from diapire in enclosure body 10, and the region between two adjacent isolating plates forms the part in dynamic oil storage region 21.Thus, lubricant oil can be stored in dynamic oil storage region 21 at least in part.Alternatively, as shown in Figure 4, multiple isolating plate can be evenly distributed on the below of intermediate shaft hole 12 and input shaft bore 13.When vehicle is in upward slope, dynamic oil storage region 21 can storage compartment lubricant oil, thus the level change of the lubricant oil in cavity can be prevented comparatively large, and then can prevent retarder 1000 from occurring the phenomenon that churning loss is too high.
