The hydrodynamic drive speed changer is characterized in that: a speed changer and a torque converter have an integrated structure; a torque converter shell is connected with a speed changer case; a driving gear and a hydraulic pump driving shaft are arranged in the speed changer case; the driving gear is assembled on the hydraulic pump driving shaft; the two ends of the hydraulic pump driving shaft are supported against the speed changer case by bearings; and one end of the hydraulic pump driving shaft is connected with the hydraulic pump. The hydrodynamic drive speed changer has the advantages of simple structure, compact assembly, convenience of maintenance, low machining accuracy, time saving, labor saving, low manufacturing cost, high coaxiality, stable and reliable performance, long service life and the like.
Description
Technical field
The utility model belongs to the speed changer technical field, particularly relates to a kind of hydraudynamic drive speed changer.
Background technique
At present, the hydraudynamic drive speed changer is the various engineering machinery vehicles kinds of drive commonly used, speed changer also attaches dynamic output unit except being the engineering vehicle walking transferring power, and its effect is to make the output of the power of motor be used for driving oil hydraulic pump to give the hydraulic system fuel feeding.
The type speed changer mostly is the hydraudynamic drive power-shifting transmission.The power of motor is delivered to hydraulic pump driveshaft through actuation gear, and hydraulic pump driveshaft drives oil hydraulic pump and rotates, thereby makes the transmission of power of motor give oil hydraulic pump, realizes the power output of motor.
The oil hydraulic pump attachment face of existing hydraudynamic drive speed changer and the center out of plumb of hydraulic pump driveshaft cause the very fast damage of bearing or oil hydraulic pump, and entire machine can not be worked.
The main cause that causes damage of bearings is that a step bearing of hydraulic pump driveshaft is installed on the torque-converters housing, and the other end Bearing Installation is on mission case.Torque-converters and speed changer generally are by the different manufacturers manufacturing, and its coaxality is difficult to assurance, thereby bearing is damaged in early days, the hydraulic pump driveshaft swing.
When assembling, measure the perpendicularity that oil hydraulic pump is installed end face and hydraulic pump driveshaft,, adopt manually to repair and grind end face if error is excessive.Such result can not guarantee precision, and efficient is low besides, and workload is big, and is high to assembler's technical ability requirement.
Summary of the invention
The utility model provides a kind of hydraudynamic drive speed changer for solving the problem that prior art exists.
The utility model purpose provides a kind ofly to be had simple in structurely, and assembling is compact, and easy to maintenance, machining accuracy is low, and is time saving and energy saving, low cost of manufacture, and the coaxality height, stable and reliable for performance, the hydraudynamic drive speed changer of characteristics such as long service life.
The utility model hydraudynamic drive speed changer adopts following technological scheme:
A kind of hydraudynamic drive speed changer, be characterized in: speed changer and torque-converters are an overall structure, torque-converters housing and mission case even are fitted together, actuation gear and hydraulic pump driveshaft are housed in the mission case, actuation gear is assemblied on the hydraulic pump driveshaft, the hydraulic pump driveshaft two ends are bearing in mission case by bearing, the hydraulic pump driveshaft one end oil hydraulic pump that links to each other.
The utility model hydraudynamic drive speed changer can also adopt following technical measures:
Described hydraudynamic drive speed changer is characterized in: actuation gear by spline on hydraulic pump driveshaft.
Described hydraudynamic drive speed changer is characterized in: the torque-converters housing is in the same place by bolt with mission case.
Advantage that the utlity model has and good effect:
The hydraudynamic drive speed changer, owing to adopted the utility model brand-new technology scheme, compared with prior art, the utility model improves the casing of torque-converters housing and speed changer, two bearings all is supported on the mission case, can eliminates hydraulic pump driveshaft out-of-alignment situation.The hydraudynamic drive speed changer changes the structure of torque-converters housing and mission case, under the prerequisite that can guarantee assembling, strengthens mission case, shortens the torque-converters housing simultaneously.Gear and hydraulic pump driveshaft splined are so that assembling.The utlity model has simple in structurely, assembling is compact, and easy to maintenance, machining accuracy is low, and is time saving and energy saving, low cost of manufacture, and the coaxality height, stable and reliable for performance, advantages such as long service life.

Embodiment
For further understanding technology contents of the present utility model, characteristics and effect, enumerate following example now, and conjunction with figs. is described in detail as follows:
With reference to accompanying drawing 1 and Fig. 2.
Embodiment 1
A kind of hydraudynamic drive speed changer, its speed changer and torque-converters are an overall structure, torque-converters housing 1 and mission case 2 have bolt to connect to be fitted together, actuation gear 3 and hydraulic pump driveshaft 4 are housed in the mission case 2, actuation gear 3 by spline on hydraulic pump driveshaft 4.Hydraulic pump driveshaft 4 two ends are bearing in mission case 2 by bearing 6, the hydraulic pump driveshaft 4 one ends oil hydraulic pump 5 that links to each other.
The concrete structure of present embodiment and work characteristics thereof:
Present embodiment hydraulic pump driveshaft 4 is supported on the mission case 3 by bearing 6, and actuation gear 2 is installed on the hydraulic pump driveshaft 4 by spline, does not have bearing hole on the torque-converters housing 1, only is fixed by bolts on the mission case 3.
The structure of design torque-converters housing and mission case, under the prerequisite that can guarantee assembling, the lengthening mission case, shorten the torque-converters housing simultaneously, make the two bearings of support hydraulic pump live axle all be installed on the mission case, thereby when making the processing mission case, can process the two bearings hole simultaneously, can guarantee the coaxality of two bearings like this.
