Fig. 2 is the partial sectional view along speed changer among the Fig. 1 of the line 2-2 among Fig. 1;
Fig. 3 is from different visual angles and the speed changer perspective view of part excision with Fig. 1 of demonstration speed changer internal component.
Embodiment
Referring now to accompanying drawing,, show the rear portion power train of a part, particularly tractor of the Work machine 10 of farm tractor form especially with reference to Fig. 1, Fig. 2 and Fig. 3.Although be shown as farm tractor, Work machine 10 can be the form of dissimilar Work machines, for example builds tractor or forestry machinery.
In the schematic representation shown in Fig. 1, tractor 10 comprises speed changer 12, and speed changer 12 is connected with rear portion differential mechanism 14, and rear portion differential mechanism 14 drives pair of rear wheels axle 16 again.Each rear-wheel spindle 16 comprises outside wheel hub 18, and corresponding rear driving wheel (not shown) is installed on this outside wheel hub 18.Speed changer 12 comprises driven shaft 20, and driven shaft 20 and IC motor 22 mechanical connections also receive the rotation input of IC motor.Driven shaft 20 transmits rotary power by the speed change gear that matches with differential mechanism 14, and differential mechanism 14 extends from the rear portion again and provides the rotation input power to rear portion differential gear set 26 (with reference to Fig. 2).
Driven shaft 20 extends through shell 72 and rotatably mounted by shell 72, and shell 72 also loads and rotatably mounted many other parts.Also be positioned at shell 28 and by shell 28 supporting be idler assembly 30, idler assembly 30 mechanically is interconnected between power input 32 and the power output 34.With reference to Fig. 2, the power input comprises input shaft 36 and the input gear 38 that is supported by input shaft 36.In an illustrated embodiment, input shaft 36 is exactly differential drive axle 24 in fact, but may provide the different rotatable drive shaft that input power is given idler assembly 30.Input shaft 36 receives input power from the driven shaft 20 that is connected with IC motor 22.
As Figure 1-3, shell 12 comprises first shell 70 and second shell 72, and described first shell comprises differential mechanism 14, and described second shell comprises a plurality of speed change gears, and total passes through with reference to character 74 indications.Speed change gear 74 is articulated in the shell 72, and described shell 72 is connected to shell 70 removedly by the fastening piece that matches with shell 70.As shown in Figure 2, speed change gear 74 selectivity connect the transmission shaft 24 that the ring gear 26 that inputs to described differential mechanism 14 is provided.
In shell 74, idler assembly 30 comprises the input shaft 44 that has gear 46, gear 38 engagements on gear 46 and the axle 24.Gear 48 meshes with the output shaft 40 that provides driving to MFWD41.As showing especially among Fig. 2, idler assembly 30 and axle 24 are spaced to be placed in compact total casing with the mechanism that is used in gear ratio.Speed reduction gearing 50 is positioned at shell 72 and shell 70 and spaced so that described mechanism takies shell 70 other spaces that are not used with axle 24.Special in shown in Figure 2, idler assembly 30 is positioned at below the axle 24 substantially, so that for oil hydraulic pump and lubricating pump device provide the space, oil hydraulic pump and lubricating pump device are totally with 76 indications of reference character.These all with the central cross of shell 72 at interval but in the holoaxial that is installed in described shell surrounds.Oil hydraulic pump and lubricating pump device 76 provide the gear of oiling agent to inside and the assembly of described speed changer 12, and other the assembly of pressurized hydraulic fluid to described Work machine 10 also is provided.
Described shell 70 also comprises multiple gear reduction assembly 77 and the service brake 78 that is installed on the shell 70 except comprising differential cross pin 14.Be arranged on the side of shell 70 with axle 16 integrant side plates 80.
Gear arrangement 12 comprises the 3rd shell 82 that is fixed to shell 70 removedly.Shell 82 comprises coupling piece 84 and comprises the input driving 87 that is used for PTO that PTO shows with reference character 86 in Fig. 3.The driving of PTO86 extends through shell 70 in PTO86 from shell 72.Described driving 87 relative differential gear set 26 are setovered so that described driving can be passed through.Described PTO provides and can be applicable to about the predetermined RPM ratio of motor input shaft 22 and the needs of looking the specific run duty factor and to connect and to break away from.Described PTO86 takies the axial depth of no more than shell 82 substantially with the further overall package that strengthens compactness.
Distributing valve body 88 to be positioned at shell 70 tops provides the central position with the valve regulated function of thinking speed changer 12 and receives compression fluid from described oil hydraulic pump and lubricating pump device 76 inner passage (not shown)s.The fluid that distributes valve body 88 to return directly passes described PTO86 does not have unnecessary pressurized with fluid so that efficient lubricating to be provided.
The result of the integral layout of speed changer 12 internal components has constituted a speed changer that has the compactness of its assembly, so that can reach the length of the whole speed changer of minimum.Extra assembly laterally is placed in side, and is the same with lubricating pump device 76 as oil hydraulic pump, or downwards, as the idler assembly 30 that is used for MFWD driving 41, so that can fill the non axial space of shell 72.The layout type of this assembly allows described speed changer 12 to be applied in the wider scope of Work machine.Simultaneously, described speed changer 12 provides all features that exist usually in such speed changer.Usually to cause the packing case of speed changer approximately be half of axial length of speed changer technology formerly to the layout of part in the speed changer.And, the speed change gear 74 that provides in the shell 72 and MFWD drive can access efficient sub-device and subsequently with shell 70 be connected reduction gear and service brake 78 that described shell 70 comprises differential mechanism 14, is correlated with.Provide the shell 86 of shell 70 opposite sides only can make the simple fixation by shell 86 and unclamp just can access and replace the quick selection that accessory is packed.
Preferred embodiment has been described, obviously, under not departing from, can have carried out various modification as the situation of scope of the present invention defined in the appended claims.
