Embodiment
With reference to Fig. 1-4, power steering pump and water pump component 10 are shown.This assembly 10 comprises power steering pump 12 and water pump 14.Power steering pump 12 comprises shell 16, and water pump 14 also comprises shell 18.Power steering pump 12 shells 16 for the sake of clarity only illustrate one by fastening piece 19(in Fig. 1) be assembled into water pump 14 shells 18.As shown in Figure 2, power steering pump 12 comprises rotatable shaft 13.Rotatable shaft 13 is driven by the motor (not shown), turns to fluid to pressurize as those skilled in the art are known with distributed power.The axle 13 of power steering pump 12 drives water pump 14.
As shown in Figure 2, water pump 14 shells 18 are formed by case member 20,22 structures of a pair of coupling.Case member 20,22 is fastened to together by a series of fastening piece 24.Packing ring 26 is positioned between the case member 20,22 of two couplings, so that two case members 20,22 connection sealing, thereby prevent that freezing mixture from leaking into surrounding environment.Case member 20,22 connection are defined among the 28(of pumping chamber of freezing mixture such as Fig. 3 the most clearly visible).
As in Fig. 2 and 3 as seen, water pump 14 also comprises bearing 40.Bearing 40 can be the two row ball bearing that comprises outer ring 42, inner ring 44 and ball 46.Although be preferable for bearing 40 two row ball bearings, can adopt the bearing of other type, include but not limited to it is needle bearing.Bearing 40 shown in Fig. 2 comprises for bearing lubricant being remained in the bearing 40 and preventing two Sealings 48 that pollutant disturbs bearing 40 suitably to work.The outer ring 42 of bearing 40 is fixing with respect to the part 20 of water pump 14 shells 18.The inner ring 44 of bearing 40 is formed on the outer end 36 of 14 32 on water pump.Although inner ring 44 and axle 32 are depicted as a body unit, be understood that axle 32 can form the unit that separates with inner ring 44, but can be such as coupling together by being press-fitted.
The outer end 36 of the axle 32 of bearing 40 supporting water pumps 14.In addition, axle 32 suspends by bearing 40, with supporting with support impeller 30.Advantageously, thisly support impeller 30 by bearing 40 and can in water pump 14 operation and impeller 30 rotation processes, prevent 32 excessive deflection in the water pump 14.This can produce the better sealing of water pump 14, thereby the frequency that refills freezing mixture is reduced, and makes the longer service life of the Sealing 46 of water pump 14.
As mentioned above, bearing 40 also comprises Sealing 46.Sealing 46 is arranged between impeller 30 and the bearing 40, so that the freezing mixture in the pumping chamber 28 and bearing 40 sealings are opened.As shown in Figure 3, Sealing 46 comprises installs the collar 48, and this installations collar is fixed to case member 20, and with water pump 14 in spools 32 shoulder 50 adjacency.Impeller 30 and the installation collar and Sealing 46 adjacency.
The outer end 36 of the axle 32 of water pump 14 cooperates with the end 52 of the rotatingshaft 13 of power steering pump 12.Axle 13,32 cooperation is transmitted the interaction that profile 54 and cloudy moment of torsion transmit profile 56 by positive moment of torsion and is carried out, wherein, profile 54,56 by a profile is slided axially within another profile or on cooperate.As the most clearly visible among Fig. 4, the rotatingshaft 13 of power steering pump 12 forms positive moment of torsion and transmits profile 54, and the inner ring 44 of bearing 40 forms cloudy moment of torsion transmission profile 56.Perhaps, such as not integrally formed but form independent parts and be press fitted under the situation on the axle 32 with axle 32 at the inner ring 44 of bearing 40, the axle 32 of water pump 14 can form cloudy moment of torsion and transmit profile 56.Although be understood that in the embodiment shown in Fig. 1-4, the axle 13 of power steering pump 14 forms positive moment of torsion and transmits profile 54, and the inner ring 44 of bearing 40 forms cloudy moment of torsion transmission profile 56, and sun/cloudy orientation can be put upside down between water pump 14 and power steering pump 12.
Moment of torsion transmits profile 54,56 and shown in Fig. 2-4 be spline, yet, can be understood by the present invention to allow sun and cloudy profile other moment of torsion transmission profile in axial sliding together.Other moment of torsion of carrying out this function transmits that profile includes but not limited to be that hexagonal, two hexagonal, five jiaos, D shape key, four jiaos, wabbler, pan head screw (torq-set), three are wing, three four jiaos, bull transmission (polydrive), rice word groove, cross recess, unidirectional, groove transmission (slot drive) and interior hexagonal (bristol).As shown in Fig. 2 and 3, the cooperation that positive and cloudy moment of torsion transmits between the profile 54,56 can be protected by O shape ring 58, and this O shape ring slides in the end 52 of the axle 13 of power steering pump 12.This O shape ring 58 prevents that any foreign particles from hindering the cooperation between sun and the cloudy moment of torsion transmission profile 54,56.
Because transmitting profile 54,56, sun and cloudy moment of torsion allow axle 13 inner rings 44 with bearing 40 of power steering pump 12 to endwisely slip, so the assembly and disassembly of power steering pump and water pump component 10 need few step.For example, can be by from tapped hole 60(as shown in Figure 2) remove three fastening piece 19(a fastening piece 19 for the sake of clarity only be shown among Fig. 1) otherwise come from water pump 14 pull down power steering pump 12 or, these fastening pieces pass the part 20 of power steering pump 12 shells 16 and water pump 14 shells 18.In case removed fastening piece 19, water pump 14 and power steering pump 12 can endwisely slip separated from one another away from another by making one in the pump 12,14.This method allows effective assembly and disassembly of power steering pump 12 and water pump 14 assemblies 10.
The description of front relates generally to a preferred embodiment of the present invention.Although noted various modification in the scope of the invention, should reckon with that those of ordinary skill in the art will recognize now the additional variations that becomes apparent probably from the disclosing of the embodiment of the invention.Therefore, scope of the present invention should be determined by following claims, and should do not limited by top specification.
