Definitions

  • This invention relates to improvements in electric motor driven hydraulic pumps, for example of the type used in hydraulic suspension systems for vehicles.
  • ECUs electronice control units
  • pcbs printed circuit boards
  • US-A-6091 174 describes a pump having a casing extended to form a casing for electronics.
  • a lead-frame assembly may be implemented that retains and connects all the high power components, for example including a power-module of bare die FETs.
  • the low power electronics may be mounted on a pcb board which is mounted on and connected to the lead-frame.
  • the low power electronics may be mounted on a traditional FR4 pcb board which is mounted on and connected to the lead-frame.
  • the lead-frame also includes a system connector moulded into it.
  • the lead frame may also include mouldings adapted to guide the connectors of a stator assembly through the lead frame.
  • the lead frame may also include mouldings adapted to guide the connectors of a stator assembly through the lead frame, for connection to the bare die FETs
  • the lead frame may include integrally moulded portions for housing components of a three hall effect sensor.
  • a support frame may be provided which together with a closure lid covers the electronics of the motor.
  • Our invention has the advantage of achieving optimum space and conserving costs. It is not necessary, in this construction, to provide a separate housing for the electronics.
  • a clamping means may be provided for releasably connecting the pump sub-assembly to the electronics sub-assembly.
  • the clamping means may secure the support frame to a cup shaped housing of the pump sub-assembly.
  • the pump/rotor sub-assembly may comprise a housing for a pump and a rotor assembly attached to the pump and sealed by a can within the pump housing.
  • the pump sub-assembly may comprise a housing for a pump and a rotor assembly attached to the pump and sealed by a can within the pump housing.
  • the support frame On assembly, the support frame may be introduced to the pump housing to place the stator around the rotor whereby the pump, the stator and the electronics are sealed by the pump housing, the support frame and the closure member.
  • the motor with the pump and the motor drive and control electronics is integrated into a single case, preferably a single cast housing.
  • the electric motor driven hydraulic pump illustrated in Figure 1-5 of the accompanying drawings comprises two sub-assemblies 1 and 2.
  • a first of the two sub-assemblies is associated with a casting 3 of cup-shaped outline and the second with a support frame 4 which are clamped together at adjacent ends by a circumferentially extending clamping band 5.
  • the casting 3 defines a housing for the rotor of an electric motor 6 and a pump impeller 7.
  • the impeller 7 is driven by a drive shaft 8 driven by the rotor 9 of the motor and which is enclosed within a stainless steel can 10 which the stator 11 surrounds.
  • the can is preferably manufactured from a non-magnetic material preferably stainless steel.
  • the open end of the casting 3 is closed by the support frame 4 by the clamping action of the band 5 as described above.
  • the support frame is of die cast construction and defines a mounting for a lead frame 12, the support frame 4 and the lead frame 12 include connecting paths from the motor to the electronics for controlling operation of motor 6.
  • the lead frame provides a mounting for a circuit board 14 and also includes a connector 13.
  • the lead frame 12 also includes a moulded bare die FET module indicated at 12' and integrally moulded portions 12" housing a hall effect sensor.
  • the lead frame has additional mouldings 12"' each having an opening through which respective connectors 11' from the motor stator can pass to be joined with the FET leads.
  • the lead frame and electronics are enclosed within an end cover 15.
  • the sub-assembly 1 is built by inserting a further assembly comprising the pump impeller 7 and associated components, the shaft 8, the rotor 9, the pump housing 16 and the can 10. The further assembly being located within the housing 3 and then being secured with a circlip. The completed sub-assembly 1 then forms a stand alone sealed unit in which all the elements of the pump can be hydraulically tested prior to final assembly with the electronics.
  • the sub-assembly 2 is assembled by mounting the board 14 carrying the electronics on the lead frame 12 and then locating the connector 13 of the lead frame through the opening 4' in the support frame 4. Once mounted in this position the bare die FET module is exposed on the side of the lead frame adjacent the support member 4 such as to abut the spigot 4" on the support member 4. A thermal compound may be applied between the abutting surfaces.
  • stator connectors 11' are inserted through respective openings in the support frame 4 and the lead frame 12 to be joined with the FET leads in known manner.
  • the support frame 4 is configured to support the stator 11 in its final position on sub-assembly 2.
  • sub-assembly 2 The final part of sub-assembly 2 is to mount the cover 15 in place by way of a snap fit connection with the edge of the lead frame 12.
  • the completed sub-assembly 2 then forms a stand alone unit in which the electronics and stator can be tested prior to final assembly with the pump assembly.
  • stator 11 of assembly 2 is assembled such as to surround the can 10 of assembly 1.
  • the assembly is completed by securing the clamping band 5 in position to clamp mating faces of the casting 3 and the lead frame 2 into engagement. In this final position, it is notable that the bare die FET module on the lead frame 12 is in contact with the support frame 4 as described above, which serves to help dissipate heat.
  • each of the two sub-assemblies 1 and 2 can be manufactured separately, and tested individually.
  • Each of the two sub-assemblies 1 and 2 can be manufactured at different locations and then both supplied to the customer for final assembly, for example on a vehicle during production.
  • the two sub-assemblies can simply be assembled together and then clamped with mating faces in engagement as described above.
  • stator could be part of sub-assembly 1 and the electronics alone would be a separate sub-assembly.
