- a torque sensor assembly illustrated in accordance with the present invention.
- the torque sensor assembly 10 is preferably adapted to be installed onto a pinion shaft 28 (a portion of which is shown in Fig. 3), which is part of a vehicle steering system (not shown).
- the illustrated torque sensor assembly 10 includes a housing 12, a carrier 14, a pair of flux concentrators 16, a pair of hall effect IC's (integrated circuits) 18, a printed circuit board 20, a cover 22 and a stator 24 disposed on the pinion shaft S.
- the torque sensor assembly 10 can be assembled as follows.
- the stator 24 is disposed on the pinion shaft 28 and then the housing 12 is disposed on the pinion shaft 28 relative to the stator 24.
- the flux concentrators 16 and the hall Effect IC's 18 are disposed in the carrier 14 and the printed circuit 20 is installed on the carrier 14 to produce a carrier assembly.
- the carrier 14 is preferably provided with a positioning or locating means or member. In the illustrated embodiment, this is illustrated as being a pair of "upstanding" projections 14A on the carrier 14 which are disposed or received in a pair openings 20 A provided in the printed circuit board 20.
- this carrier assembly is disposed in a cavity or opening 12A the housing 12.
- the housing 12 is preferably provided with a positioning or locating means or member.
- this is illustrated as being a pair of "upstanding" projections 12B (only one of which is shown), on the housing 12 which are disposed or received in a pair of openings 14B provided in the carrier 14.
- the cover 22 is installed and secured to the housing 12 by preferably a laser welding process along an outer periphery of the cover 22.
- the housing 12 is preferably provided with a positioning or locating means or member. In the illustrated embodiment, this is illustrated as being a stepped portion or shoulder 12C on the housing 12 to receive the cover 22 therewithin.
- the housing 12 and the cover 22 are preferably formed from suitable like materials, such as for example plastic, which enable the laser welding process to be utilized to secure the housing 12 and the cover 22 together.
- the housing 12 and/or the cover 22 may be formed from other suitable materials, which may be like and/or non-like materials, which enable the laser welding process to be utilized or any other suitable process or method to be used in order to preferably permanently attach the cover 22 to the housing 12 in a preferably water-tight manner.
- suitable materials for the cover 22 and/or the housing 12 can include for example, non-metal materials and/or metal materials.
- suitable processes or methods to preferably permanently attach the cover 22 to the housing 12 can include for example, other suitable welding processes selected depending upon the materials for the cover 22 and the housing 12 and/or the use of a suitable adhesive.
- One advantage of the first embodiment of the torque sensor assembly 10 is that after the carrier assembly has been installed in the housing 12, the cover 22 is permanently secured to the housing 12 by, in the preferred embodiment, a laser welding process. As a result of this, the chances of water, dirt, debris, or other foreign bodies or contaminants entering past the cover 22 and into the cavity 12A of the housing 12 is virtually reduced or eliminated since the laser welding process is operative to form a fluid-tight seal between the cavity 12A of the housing 12 and the cover 22.
- the structure or configuration of one or more of the components of the first embodiment of the torque sensor assembly 10 can be other than illustrated and described if so desired.
- the method for assembling and/or securing the components of the first embodiment of the torque sensor 10 together can be other than illustrated and described if so desired.
- a torque sensor assembly illustrated a second embodiment of a torque sensor assembly, indicated generally at 30, constructed in accordance with the present invention.
- the illustrated torque sensor assembly 30 includes a housing 32, a pair of flux concentrators 34, a pair of hall effect IC's 36, a stator 38, and connector terminals and lead frame 40.
- the torque sensor assembly 30 can be assembled as follows. First, at least the illustrated components of the torque sensor assembly 30, which include at least the flux concentrators 34, the hall effect IC's 36, the stator 38 and the connector and lead frame 40 are disposed in a tooling mold 42 (which is schematically shown in Fig. 16). Next, the housing 32 is overmolded in situ to produce the finished or overmolded torque sensor assembly 30 of the second embodiment. To assist in this, in the illustrated embodiment the housing 32 is preferably formed from a suitable material which can be utilized in a suitable molding process, such as for example plastic, which can be utilized in an injection plastic molding process or other suitable molding process.
- the housing 32 is formed as an overmolded housing. As a result of this, water, dirt, debris, or other foreign bodies or contaminants entering through the housing 32 to the components housed therewithin is virtually reduced or eliminated since the overmolding process is operative to enclose the components of the torque sensor assembly 30 which are housed therein in a fluid-tight manner.
