The fixed shaft type transmission mainly comprises a torque converter, a transmission gear and a connecting seat, wherein the torque converter is fixedly connected with the transmission through a bolt, a power takeoff is arranged on the torque converter, the fixed shaft type transmission is provided with a transfer case which is fixedly connected with the transmission, and a front output flange and a rear output flange are arranged on the transfer case; and a gear pump is built in the torque converter. The fixed shaft type transmission is mainly used for loading machines or excavating and loading machines and other engineering machines.
Description
Technical field
The utility model belongs to parts on the loader, belongs to engineering machinery manufacturing technology field, specifically, relates in particular to a kind of fixed shaft type speed changer.
Background technique
The torque converter that present most wheel loader adopted is made up of two hydrotransmitters and planet transmission.Fluid torque converter adopts single-stage, two-phase, quaternary part torque-converters.Speed changer is planetary drive mechanism, and the second gear that advances falls back one grade.The subject matter of the existence of this torque converter: owing to be subjected to structural limitations, free wheel device force-bearing situation and lubricating condition are relatively poor, easily lose efficacy in the using process, thereby cause transmission reliability poor; Adopt flow deviding type hydraulic machine transmission in the power, power loss is big, causes tow-rope horsepower, efficient lower, and it is narrower efficiently to distinguish scope; Planetary complex structure, dimensional chain is longer, and dimensional accuracy is difficult for guaranteeing, causes the speed changer noise bigger, the manufacturing difficulty, maintenance is inconvenient.
Summary of the invention
The purpose of this utility model is to provide a kind of fixed shaft type speed changer, and free wheel device influences greatly to solve being subjected to that planet transmission exists in the prior art, poor reliability, power loss is big, tow-rope horsepower is lower, efficiently distinguish narrower, the planetary complex structure of scope, the manufacturing difficulty, keep in repair defectives such as inconvenience.
The utility model has taked following technological scheme to realize: a kind of fixed shaft type speed changer, comprise torque-converters, gearbox and connecting base, torque-converters and gearbox are bolted to connection, torque-converters is provided with power take-off, described fixed shaft type speed changer is provided with transfer case, transfer case is fixedlyed connected with gearbox, output flange and back output flange before transfer case is provided with; The built-in gear pump of torque-converters.
Described fixed shaft type speed changer can be provided with filter cleaner, vernier scale, break and automatically controlled speed change valve; Described gear pump is crescent gear pump preferably.
Compared with prior art, the beneficial effects of the utility model are: speed changer advances, retreats each four gear, and gear is many, the speed ratio regulation range is big, can give full play to engine power; Adopt the crescent gear pump technology, the volumetric efficiency height, the life-span is long, and noise is low; Adopt electric liquid shift+KD gear change system, one grade and second gear gear-change operation employing KD gear shift function have been simplified operation, have reduced operator's labor intensity; The modular design of gearbox is divided into two traditional gearbox, is divided into gearbox and transfer case, increases one-level deceleration form, is convenient to modular design and manufacturing, to adapt to different tonnages, to be convenient to mate the loader product that different drive ratios requires; Adopt the built-in technology of oil duct, avoid the external leakage of oil duct.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Among the figure: 1, torque-converters; 2, power take-off; 3, gearbox; 4, transfer case; 5, break; 6, preceding output flange; 7, vernier scale; 8, back output flange; 9, filter cleaner; 10, automatically controlled speed change valve; 11, connecting base; 12, crescent gear pump.
A kind of fixed shaft type speed changer, comprise torque-converters 1, gearbox 3 and connecting base 11, torque-converters 1 and gearbox 3 are bolted to connection, torque-converters 1 is provided with power take-off 2, described fixed shaft type speed changer is provided with transfer case 4, transfer case 4 is fixedlyed connected with gearbox 3, output flange 6 and back output flange 8 before transfer case 4 is provided with; Torque-converters 1 built-in crescent gear pump 12; The fixed shaft type speed changer is provided with filter cleaner 9, vernier scale 7, break 5 and automatically controlled speed change valve 10.
Torque-converters 1 built-in crescent gear pump 12 and turbine group, gearbox 3 built-in second gear clutch assemblies, three fourth gear clutch assemblies and the clutch assembly of forward-reverse shelves, transfer case 4 built-in driving gear set.
When using the utility model, by connecting base 11 the utility model is fixed on the vehicle frame, motor connects the elastic plate of torque-converters 1, transmission of power is to torque-converters 1, power is delivered to gearbox 3 and transfer case 4 behind the turbine group bending moment of torque-converters 1, be connected the transmission shaft output torque by preceding output flange 6 respectively with back output flange 8 again; Automatically controlled speed change valve 10 is used for selecting each gear to open, and controls the pressure of each gear pressure oil simultaneously, makes the piston pressing friction sheet in the isolating frame come transferring power; Break 5 is used for control torque output.
The utility model is simple in structure, easy to manufacture, reliability is high, shifting of transmission is convenient freely simultaneously, the impact of employing buffer technology is little, gear range is big, can realize stepless change within the specific limits, variation to external load has adaptive ability, can give full play to engine power performance and improve Economy, long service life not only can be used for loader, also can be used for loader-digger and Other Engineering machinery.
