Abstract
The utility model relates to a hydraulic power system of clutch mechanism arranged between a power input axle and a driving gear axle of a gear pump, which comprises the gear pump, a change valve, an overflow valve, an input mechanism of dynamic force and the clutch mechanism. The deflector rod in the clutch mechanism drives a sliding sleeve to axially move and combines with an input axle or separates with the input shaft. According to the requirement of use, the gear pump can separate or combine with the input axle, which can save energy consumption and extend service life; the other feature is that the gear pump does not have a front cover, and a casing of the input mechanism of dynamic force, the casing of the gear pump and an inverting valve body are connected integration by screws. The utility model has the advantages of compact structure, high integration degree and saving cost price.
Description
The utility model relates to hydraulic transmission and control technique field, is specifically related to have between power input shaft and the gear pump driving gear shaft hydraulic power unit of clutch mechanism.
Existing hydraulic power unit is with gear pump, and selector valve and relief valve are made one, and the bonnet of gear pump is the valve body of selector valve, and with protecgulum, the valve body of gear pump body and selector valve connects into an integral body with connecting bolt.The mounting flange face of the mounting flange face of gear pump protecgulum and positioning spigot and power input mechanism housing and positioning spigot cooperate, with screw both are fastenedly connected, the flat mouth of input shaft and driving gear is connected cooperation, when main frame power drove the belt pulley rotation, input shaft drove driving gear and driven gear rotation.The deficiency that this hydraulic power unit exists is: the one, when hydraulic power unit is not worked, belt pulley driven gear pump driving gear and the driven gear rotation that does as usual, consume main frame power in vain, shorten the Acceptable life of hydraulic power unit, and make the hydraulic system heating.The 2nd, this device level of integration is not high, and power input mechanism and gear pump are still two discrete parts, and after both linked into an integrated entity, gear pump protecgulum reality had become a unnecessary part, consumes raw material more, increased product cost.
The purpose of this utility model is, a kind of integrated degree height is provided, between input shaft and the driving gear can in conjunction with or the hydraulic power unit that separates.
The purpose of this utility model can realize by following technical proposals: its structure includes gear pump, selector valve, relief valve, power input structure and clutch structure, they are assemblied in by the commutation valve body, in the housing that defeated pump case of tooth and input mechanism housing constitute, the technical characterstic of this device is: put between the driving gear shaft of the input shaft of power input structure and gear pump clutch structure is housed: one end face is arranged is the flip sleeve of tooth embedding structure to head on the shaft extension of gear pump driving gear shaft, one end of the input shaft of power input mechanism is shaped on castellated structure, activity is installed in the dead man on the power input mechanism housing, in the rectangle annular groove that patches garden week outside flip sleeve, drive the slip interplanting and move axially, with input shaft in conjunction with or separate.The commutation valve body, gear pump case is connected with fastener with input mechanism housing three, and power input mechanism and clutch mechanism, gear pump and selector valve are become one.
The good effect that the utility model produces is: input power can by clutch mechanism, make gear pump combination or separation with it as required, can reduce energy consumption, prolongs the working life of hydraulic power unit, and it is warm to reduce hydraulic system oil.Commutation valve body, gear pump case are connected one with the input mechanism housing, without the gear pump protecgulum, reduce fixing link, compact structure, and cost reduces, and improves whole integrated degree.
Below in conjunction with accompanying drawing, the utility model technical application content is described in detail.
Fig. 1 is a topology view of the present utility model.
Fig. 2 is a selector valve body structure view.
The bonnet 3 of gear pump is the valve body of selector valve, selector valve, relief valve are installed in valve body 3, its selector valve, relief valve, it is identical with the conventional device connection that oil duct between gear pump connects, and as shown in Figure 2: the filler opening 16 of selector valve is the oil outlet of gear pump, and the oil outlet of selector valve is connected with oil cylinder, oil duct in relief valve valve port 18 and the valve body interlinks, and overflow spool 17 roof pressures are on overflow valve port 18.The driving gear 5 of gear pump and the tooth axle of driven gear 2 cooperate activity to be installed on the gear pump case 4 with axle sleeve, the skeleton self-tightening oil seal 8 in the endoporus of the axle journal of driving gear 5 and power input mechanism housing 13 matches, isolated oil leakage.Be equipped with flip sleeve 12 on the driving gear shaft 6, adopting the match right-hand member of flip sleeve 12 of internal spline shaft extension is tooth embedding structure, input shaft 14 left sides of power input mechanism are corresponding with it tooth embedding structures, be connected with flip sleeve 12, input shaft 14 is supported by bearing, bearing is by the end cap axial compression, and its other end has a belt pulley 15, and input shaft 14 and belt pulley 15 constitute the power input structure.A dead man 10 in the activity attaching on power input mechanism housing 13, one spheroid 9 is arranged in the middle of the dead man 10, be installed on the housing 13 by sheet rubber and hemispherical cover plate activity, the inner of dead man 10 patches outside flip sleeve 12 in the rectangle annular groove 11 of garden on week, manually dead man 10 remain on position that the operator sets to left and right stir mobile, the right side, left separate or combination with input shaft to moving vertically to drive flip sleeve 12 by annular groove 11, flip sleeve 12, the end face that dead man 10 and input shaft 14 have tooth embedding structure constitutes clutch structure, and is shown in Figure 1.In conjunction with the time, belt pulley 15 drives driving gears 5 rotations with input shaft 14, driven gear 2 is rotation synchronously also, gear pump sucks hydraulic oil from inlet port, by pressing oil duct to be pressed into selector valve from filler opening, hydraulic power unit is in work condition state; During separation, flip sleeve 12 separates with input shaft 14, and hydraulic power unit is not worked.Commutation valve body 3, gear pump case 4 and power input mechanism housing 13 usefulness screws 1 are fastenedly connected one, on the junction plane of gear pump case 4 and power input mechanism housing 13, the rationed marketing hole is arranged, installing and locating pin 7 has guaranteed the coaxality of driving gear axle journal and input shaft 14.
