The number in the figure explanation:
Oil pump electrical machinery 1, power steering oil pump 2, insulator 3, Oil pump electrical machinery female splined shaft 4, oil pump castellated shaft 5, assembling bolt 6, bearing 7.
The specific embodiment
In order to understand better according to automatically controlled power steerig pump of the present utility model, below in conjunction with the specific embodiment of accompanying drawing description according to automatically controlled power steerig pump of the present utility model.
With reference to figure 1.Automatically controlled power steerig pump of the present utility model comprises Oil pump electrical machinery 1 and power steering oil pump 2, and described Oil pump electrical machinery 1 adopts the mode of direct connection interpolation type to link together with power steering oil pump 2.Vehicle and deflector thereof for certain model, the design of maximum oil pump delivery is determined, when setting higher motor speed, choose the traffic requirement that less displacement oil pump just can satisfy oil pump, thereby reduced the bulk of automatically controlled power steerig pump, have little, the compact conformation of volume, be convenient to passenger vehicle operator and make author's installation and maintenance; This product running steadily simultaneously, noise is low, vibration is little, improves the comfort level of passenger vehicle.
Oil pump electrical machinery 1 in the utility model passes through spline interpolation direct connection with automatically controlled power steerig pump 2, with two assembling bolts 6 Oil pump electrical machinery 1 and automatically controlled power steerig pump 2 is fixedly connected again; Adopt two class B insulations: a class B insulation adopts the high special oil pump motor of the class of insulation, two class B insulations realize that by increase insulator 31 of Oil pump electrical machinery the connection electricity can not take place for automatically controlled power steerig pump assembly and automobile, thereby have guaranteed automatically controlled steering pump assembly safety in utilization.
Oil pump electrical machinery 1 is selected the special oil pump motor of class of insulation H level for use.The class of insulation of motor refers to the temperature classification of its used insulating material, divides A, E, B, F, these five ranks of H level.Their permission operating temperature is respectively: 90,105,120,130,155,180 ℃, the heat resisting temperature of insulating material is 180 ℃ in the Oil pump electrical machinery in the utility model thus.
Be provided with Oil pump electrical machinery female splined shaft 4 in the mouth of Oil pump electrical machinery 1; Be provided with oil pump castellated shaft 5 in the mouth of power steering oil pump 2.
Described oil pump castellated shaft 5 is male splined shaft, and it matches with Oil pump electrical machinery female splined shaft 4.Castellated shaft is for the appearance at axle has keyway longitudinally, and the revolving part that is enclosed within on the axle also has corresponding keyway, can keep with axle rotation synchronously.In rotation, what have can also do longitudinal sliding motion at axle, as the gearbox gear-shift gear etc.Will keeping of also having is reliably locked, usually uses at braking, steering hardware.Castellated shaft in the utility model is selected rectangular spline axle or involute splined shaft for use.Castellated shaft works to transmit moment of torsion between Oil pump electrical machinery and power steering oil pump.
The length of Oil pump electrical machinery female splined shaft 4 is greater than the length of oil pump castellated shaft 5.When automatically controlled power steerig pump was worked, at first Oil pump electrical machinery started, and meanwhile Oil pump electrical machinery is delivered to power steering oil pump to the moment of torsion of output by Oil pump electrical machinery female splined shaft and oil pump castellated shaft, and obtain power steering oil pump and can realize fuel feeding this moment.Since the length of Oil pump electrical machinery female splined shaft 4 greater than the length of oil pump castellated shaft 5 when automatically controlled power steerig pump assembly takes place to shake behind the automobile starting, oil pump castellated shaft 5 can leave certain distance and slide in Oil pump electrical machinery female splined shaft 4, oil pump castellated shaft 5 just can not touch the bottom of Oil pump electrical machinery female splined shaft 4 like this, vehicle has been played the effect of damping.
As shown in Figure 2, be equipped with bearing 7, seal ring, insulating mat in the mouth of Oil pump electrical machinery 1 and power steering oil pump 2.Be equipped with insulating mat in the mouth of Oil pump electrical machinery 1 and power steering oil pump 2, Oil pump electrical machinery 1 and power steering oil pump 2 main parts size are insulated fully, thereby when electric leakage takes place in Oil pump electrical machinery 1, whole automatically controlled power steerig pump can outwards not leak electricity, so just fundamentally eliminate the potential safety hazard of automatically controlled power steerig pump, greatly improved the safety that automatically controlled power steerig pump uses.
Oil pump electrical machinery 1 is identical with the revolution of power steering oil pump 2.For vehicle and the deflector thereof of certain model, the design of maximum oil pump delivery is determined, when setting higher motor speed, chooses less displacement oil pump and just can satisfy the traffic requirement of oil pump, thereby reduced the bulk of automatically controlled power steerig pump.
Oil pump electrical machinery 1 is linked together by assembling bolt 6 with power steering oil pump 2.When after Oil pump electrical machinery female splined shaft 4 or oil pump castellated shaft 5 wear and tear, needing to change, only need back out assembling bolt 6 and can change Oil pump electrical machinery female splined shaft 4 or oil pump castellated shaft 5.
The mount pad of Oil pump electrical machinery 1 is provided with insulator 3.Set up insulator 3 at the mount pad of Oil pump electrical machinery 1, make automatically controlled power steerig pump assembly and automobile erecting frame insulate fully, even when electric leakage takes place automatically controlled power steerig pump assembly, can not leak outside to automobile yet, so just fundamentally eliminate the potential safety hazard of automobile electric leakage, improved the safety that automatically controlled power steerig pump assembly uses widely; The automatically controlled power steerig pump assembly of insulated type also has more advantages of higher of energy-conserving and environment-protective, longer service life, service efficiency height and cost performance.
Because in light weight, easy processing that epoxy resin has, physical strength height, withstanding corrosion and the high characteristics of insulativity are so insulator 3 selects for use epoxy resin as work material.
It will be apparent to those skilled in the art that automatically controlled power steerig pump of the present utility model comprises the combination in any of each several part in this specification sheets.As space is limited and in order to make specification sheets simple and clear, these combinations not to be introduced one by one in detail at this, but after having seen this specification sheets, the scope of the present utility model that the combination in any of the each several part that is made of this specification sheets constitutes is self-evident.
