It is bending moment device assembly 16 to be arranged in the housing 12 of speed changer 10, in bending moment device assembly, according to traditional reality
Trample, including such as pump 18, turbine 20 and stator 22.Always according to traditional practice, flex plate or similar mechanism 24 are attached
Torque converter pump 18 is driven to torque converter pump 18 and from the bent axle (output shaft) of prime mover (being also not shown).After torque converter pump 18
Portion includes rigidly attached with one heart axle, collar or hub 26, which defines first axle.
It is being integrally formed therewith, be affixed directly to or for example by complementation the male and female spline 28 to engage each other revolve
It is chain drive sprocket 30 to turn be connected to the axle, collar or hub 26.Sprocket wheel 30 is therefore with the output speed and bending moment of prime mover
The input speed rotation of device 16, and be always rotating when prime mover works.Chain drive sprocket 30 includes setting around its outer rim
The multiple chain soldered tooths 32 put.What is wrapped up around a part for chain drive sprocket 30 and engaged and driven by multiple teeth 32 is single
Loop chain or more loop chains 34.
The monocyclic chain or more loop chains 34 extend through the opening 36 in installing plate or boss 40, and installing plate or boss are preferred
Ground is integrally formed or is integrally formed in the housing 12 with the housing of speed changer 10 12.Alternatively, installing plate or boss 40 can
Individually cast or manufacture and by any suitable means, such as threaded fastener, be attached to case of transmission 12.
By any suitable means, such as multiple threaded fasteners, i.e. machine bolt 44, installing plate or boss are attached to
40 be middle casing 50, and the housing packing ring 52 seals.It is arranged in middle casing 50 and collar or the driving of hub 26 and chain
It is that it, which has, surrounds its outer rim by drive sprocket 56 that the first axle of sprocket wheel 30, which is spaced apart and in parallel second axis,
Multiple chain soldered tooths 58, these teeth are engaged and driven by described monocyclic chain or more loop chains 34.Interference is passed through by drive sprocket 56
The male and female spline 62 coordinate, being bonded with each other or other means, such as the footpath of drive pin, positioning screw or hollow stub shafts 60
To expansion, hollow stub shafts 60 are connected to.Alternatively, it is integrally formed or is manufactured by drive sprocket 56 and short axle 60, such as by
Powdered-metal is formed or manufacture.Therefore more loop chains 34 are arranged on the plane vertical with axle or hub 26 and the first axle of short axle 60
It is interior.
Short axle 60 is rotatably supported on bearing 66, bearing 66 and then is supported in middle casing 50.It is excellent
Selection of land, middle casing 50 include checking plate or lid 68, and it includes packing ring 70 and fixed by suitable threaded fastener 72
To middle casing 50.Check that plate or lid 70 are provided to the selective passage of the inside of middle casing 50 to be for example advantageous to monocyclic

Such as multiple female splines 78 or similar inner teeth, these splines or toe joint merge the pump input shaft 84 for driving hydraulic pump 90
On male form spline 82 or similar external teeth.Hydraulic pump 90 can be fixed directly to middle casing 50 or the axle fixed to adaptation
Ring or ring 92, the collar or ring 92 are secured to middle casing 50 and and then tight by screw thread by multiple threaded fasteners 94
Firmware 96 is secured to hydraulic pump 90, and two of which interface is all sealed by packing ring 98.The collar or ring of adaptation can be used for adapting to
The large-scale installation surface of different hydraulic pumps 90.According to traditional practice, hydraulic pump 90 includes suitable import (suction)
With outlet (discharge) accessory or connector 100, it is connected to supply (supply) and outlet (pressure) pipeline (not shown).
It should be appreciated that some benefits provided according to the chain of present invention driving power takeoff.First, chain kit is usual
Reduce the space for the power takeoff using gear shared by the power takeoff in speed changer.Second, and further
It is secondary relative to gear apparatus, Chain conveyer do not show because engine torque excitation and caused by gear sound of laughing ring problem and because
This more undisturbedly runs.3rd, because chain and pump are all driven from the input to torque-converters, as long as transported in prime mover
During row, power is just supplied to hydraulic pump.This with respect to be for the construction of power takeoff by the output driving of torque-converters it is significant and
Worth improvement, the lower torque-converters of that construction are exported only when vehicle moves to rotate and therefore offer power.Finally,
Make middle casing, permission hydraulic pump is integrally formed by drive sprocket, axle, adaptation ring and other parts and speed changer by quick and straight
Ground connection installation, without requiring to buy power taking device assembly, thus provide significant value to consumer.
Change that is that description of the invention is substantially merely exemplary and not departing from spirit of the present invention is also considered as at this
In the range of invention.This change is not to be regarded as a departure from the spirit and scope of the present invention.
