Abstract
The utility model relates to a hydraulic gear pump driving device, which comprises a belt pulley installed on a clutch and a hydraulic gear pump which is in linkage with the belt pulley. The hydraulic gear pump driving device is characterized in that the hydraulic gear pump is arranged on the external side of the belt pulley and fixedly installed on a gear pump support, the gear pump support is fixedly connected with one end of a beam, the other end of the beam is fixedly connected with a tractor rack, the belt pulley is fixedly provided with a driving block which is in driving connection with the pump shaft of the hydraulic gear pump, the driving block is provided with a slot, the front end of the pump shaft is formed in a polygon prism shape and is corresponding to that of the slot, and the front end of the pump shaft is inserted in the slot. In the hydraulic gear pump driving device, power is transmitted to the hydraulic gear pump by the driving block, saving two driving belt pulleys and driving belts in a traditional device, not only reducing the cost, but also decreasing power loss. Further the arrangement of the hydraulic gear pump is more reasonable, and after the clutch pedal is stepped, the entire device can work normally.
Description
Technical field
The utility model relates to a kind of mekydro pump drive.
Background technique
In the mekydro pump drive of existing four-wheel tractor, hydraulic gear pump is installed on the tractor rear axle, a transmission pulley is installed on the pump shaft of hydraulic gear pump, the outside that is installed in the belt pulley on the clutch also correspondence is equipped with a transmission pulley, two transmission pulleys link by belt, and hydraulic gear pump obtains power by two transmission pulleys and a belt from the belt pulley on the clutch.The intrinsic defect of this traditional device is the cost height, and the layout of hydraulic gear pump is unreasonable, and after depressing clutch pedal, whole drive unit just can not be worked.
Summary of the invention
The purpose of this utility model provides the mekydro pump drive that a kind of cost is low, hydraulic gear pump is rationally distributed.
For achieving the above object, the utility model is by the following technical solutions:
A kind of mekydro pump drive described in the utility model, comprise the belt pulley that is installed on the clutch, with the hydraulic gear pump of belt pulley interlock, its characteristics are: hydraulic gear pump is arranged on the outside of belt pulley, be fixedly mounted on the gear pump support, the gear pump support is fixedly connected on the end of crossbeam, and the other end of crossbeam is fixedly connected on the tractor frame; Be installed with drive block on the belt pulley, the pump shaft of drive block and hydraulic gear pump is in transmission connection.
Have draw-in groove on the described drive block, the front end of pump shaft is the polygon prism shape, and is corresponding with the shape of draw-in groove, and the front end of pump shaft is plugged in the draw-in groove.
In the utility model, hydraulic gear pump is arranged on the outside of the belt pulley of clutch, by drive block power is transported to hydraulic gear pump, like this, just save two transmission pulleys and drivign belt in the conventional apparatus, not only reduced cost, also reduced the loss of power.In addition, the layout of hydraulic gear pump is more reasonable, and after depressing clutch pedal, whole device can proper functioning.
Description of drawings
Accompanying drawing is a kind of embodiment's of the utility model a structural representation.
Embodiment
The utility model will be further described below in conjunction with the drawings and specific embodiments.
A kind of mekydro pump drive, as shown in drawings, comprise the belt pulley 7 that is installed on the clutch, with the hydraulic gear pump 3 of belt pulley 7 interlocks.Gearbox 8 belows are provided with crossbeam 1, and the right-hand member of crossbeam 1 is bolted to connection on tractor frame 9, and left end reaches the outside of belt pulley 7, welded gear pump support 2 at an upper portion thereof, and hydraulic gear pump 3 is fixedly mounted on the gear pump support 2.Like this, hydraulic gear pump 3 just is arranged on the outside of belt pulley 7.Be installed with drive block 6 on the belt pulley 7, draw-in groove 5 on the drive block 6, and pump shaft 4 front ends of hydraulic gear pump 3 are quadrangular, and are corresponding with the shape of draw-in groove 5, and like this, pump shaft 4 is plugged in the draw-in groove 5, has just realized being in transmission connection of belt pulley 7 and hydraulic gear pump 3.
During work, belt pulley 7 obtains power from motor, and belt pulley 7 drives drive block 6, and drive block 6 drives pump shaft 4 and rotates, and hydraulic gear pump 3 obtains power like this, and then the elevator mechanism of control tractor carries out work.
