Abstract

A throttle body having an integrated sector gear which includes a sector gear component, a bushing integrally formed with the sector gear component such that the bushing and sector gear component are a single part, and an insert, where the bushing and the sector gear formed around the insert. The insert includes a first arm and a second arm, and the insert is configurable to be formed with the sector gear and the bushing to be suitable for use with one or more packaging requirements of the throttle body.

First claim

What is claimed is:

1. An apparatus, comprising:
a sector gear component, including:
a gear member;
a first bushing integrally formed with the gear member;
an insert, a portion of the gear member integrally formed around at least two surfaces of the insert;
a shaft, the insert mounted on the shaft such that the shaft rotates as the gear member, the first bushing, and the insert are rotated;
a ridge integrally formed with the gear member, the ridge substantially circumscribing the first bushing, the outer diameter of the ridge being larger than the outer diameter of the first bushing;
a groove integrally formed with the gear member such that the ridge is substantially circumscribed by the groove;
a spring in contact with the ridge formed as part of the gear member;
a second bushing, the spring in contact with a portion of the second bushing; and
a bearing boss, the second bushing mounted to the bearing boss;
wherein the spring partially surrounds the first bushing and partially surrounds the second bushing, the portion of the gear member is formed around the insert such that the sector gear component is in a right-hand configuration or a left-hand configuration, and the position of the insert relative to the first bushing in the right-hand configuration is different than the position of the insert relative to the first bushing in the left-hand configuration.

2. The apparatus of claim 1 , wherein the sector gear component is mounted within a throttle body.

3. The apparatus of claim 2 , the throttle body further comprising:
a housing portion, the bearing boss integrally formed as part of the housing portion;
a port formed as part of the housing portion; and
a valve disposed in the port;
wherein the valve is connected to the sector gear component such that the sector gear component is used to change the valve between an open position and a closed position.

4. The apparatus of claim 3 , the throttle body further comprising:
wherein the shaft disposed in the housing such that a portion of the shaft extends into the port, and
the valve is mounted to the shaft, and the shaft moves the valve between the open position and the closed position.

5. The apparatus of claim 4 , the valve further comprising a plate, the plate mounted on the shaft such that the plate is disposed in the port.

6. The apparatus of claim 2 , the throttle body further comprising:
a gear box connected to the housing portion; and
a plurality of gears disposed in the gearbox, the sector gear component being one of the plurality of gears;
wherein the plurality of gears are used for rotating the shaft and changing the valve between an open position, a closed position, and any position there between.

7. The apparatus of claim 1 , further comprising:
a first arm formed as part of the insert; and
a second arm formed as part of the insert;
wherein the first arm and the second arm are parallel to an axis of rotation of the sector gear component.

8. The apparatus of claim 7 , further comprising:
a first section formed as part of the gear member; and
a second section formed as part of the gear member;
wherein each of the first arm and the second arm extend through one of the first section or the second section when the insert is formed with the sector gear and the first bushing.

9. The apparatus of claim 8 , wherein the first arm extends through the first section, and the second arm extends through the second section when the insert and the sector gear are in the left-hand configuration.

10. The apparatus of claim 8 , wherein the first arm extends through the second section, and the second arm extends through the first section when the insert and the sector gear are in the right-hand configuration.

11. The apparatus of claim 7 , wherein the second arm is shorter than the first arm.

12. An integrally formed sector gear, comprising:
a sector gear;
a first bushing integrally formed with the sector gear;
an insert, the first bushing and the sector gear integrally formed around at least two surfaces of the insert;
a ridge integrally formed with the gear member, the ridge substantially circumscribing the first bushing, the outer diameter of the ridge being larger than the outer diameter of the first bushing;
a groove integrally formed with the gear member such that the ridge is substantially circumscribed by the groove;
a spring in contact with the ridge formed as part of the gear member;
a second bushing, the spring in contact with a portion of the second bushing;
a bearing boss, the second bushing mounted to the bearing boss;
a first arm formed as part of the insert;
a second arm formed as part of the insert; and
a shaft, the insert mounted on the shaft such that the shaft rotates as the sector gear, the first bushing, and the insert are rotated;
wherein the spring partially surrounds the first bushing and partially surrounds the second bushing, the sector gear and the first bushing are formed around the insert in a right-hand configuration or a left hand configuration to be suitable for use with one or more packaging requirements, and the position of the insert relative to the first bushing in the right-hand configuration is different than the position of the insert relative to the first bushing in the left-hand configuration.

13. The integrally formed sector gear of claim 12 , further comprising:
a gear box having a plurality of gears, the sector gear being part of the plurality of gears and located in the gear box; and
a throttle body, wherein the gear box is connected to a throttle body.

14. The integrally formed sector gear of claim 13 , the throttle body further comprising:
a housing portion, the bearing boss integrally formed as part of the housing portion;
a port formed as part of the housing portion;
the shaft extending through the housing portion such that a portion of the shaft is disposed in the port, and a portion of the shaft is connected to and rotated by the insert; and
a valve mounted to the shaft such that the valve is disposed in the port;
wherein the plurality of gears are used for rotating the shaft and changing the valve between an open position, a closed position, and any position there between.

15. The integrally formed sector gear of claim 12 , the sector gear further comprising:
a first section where material has been removed; and
a second section where material has been removed, wherein each of the first arm and the second arm extend through one of the first section or the second section when the insert is formed with the sector gear and the first bushing.

16. The integrally formed sector gear of claim 15 , wherein the first arm extends through the first section, and the second arm extends through the second section when the insert and the sector gear are configured in the left-hand configuration.

17. The integrally formed sector gear of claim 15 , wherein the first arm extends through the second section, and the second arm extends through the first section when the insert and the sector gear are configured in the right-hand configuration.

18. The integrally formed sector gear of claim 12 , wherein the second arm is shorter than the first arm.

19. An integrally formed sector gear, comprising:
a sector gear;
a first bushing integrally formed with the sector gear;
