Definitions

  • the present invention relates to multiple output transmission systems, that is to say transmission systems with a single input shaft and a plurality of output shafts, each of which may be selectively coupled to be rotated by the input shaft. More specifically, the invention relates to a transmission system for driving a selected one or two of a plurality of drivable devices by a single drive motor including an input shaft for connection to the drive motor, a plurality of output units, each output unit including a drive member which is drivable by the input shaft, an output shaft and a clutch mechanism, and a clutch engagement actuator arranged to act on a selected one of the clutch mechanisms to connect the input shaft to the associated output shaft, thereby transmitting rotation from the input shaft to the said output shaft.
  • Such transmission systems have a number of applications, particularly in the automotive field. It is common for automotive seats to be provided with a number of dedicated actuators for adjusting the height, position and degree of recline of the seat, as well as headrest, armrest, lumbar and lateral restraint adjustment. In some cases, two actuators are provided for a single adjustment, e.g. one actuator on each side of the seat for adjusting its position or height. It would of course be possible for each actuator to include a respective electric motor but this is highly undesirable as regards cost and weight and due to the fact that space is at a premium within and below automotive seats. It is therefore known to provide each actuator in the form of an unpowered device which may be selectively connected to a single electric drive motor.
  • a further application for such transmission systems is in automotive door actuators.
  • a single motor coupled to a transmission system may be accommodated in a vehicle door and used selectively to operate one of for instance, a powered wing mirror, a powered window and a powered door luck.
  • a transmission system of the type referred to is disclosed in WO2006/008663.
  • the drive members constitute gear wheels, each of which is in mesh with one or more of the other gear wheels and one of which is connected to be rotated by the drive motor.
  • a further object of the invention is to provide such a transmission system in which the clutch mechanisms have a significantly reduced part count, overall weight, and are thus simpler and cheaper.
  • a transmission system of the type referred to above is characterised in that the drive members are carried on a common drive shaft and are rotatable with respect to it and that the clutch mechanisms are operable to selectively connect the drive members to the drive shaft to rotate with it.
  • the drive members are all permanently connected to the drive shaft and thus all rotate when the drive shaft rotates.
  • the clutch mechanisms are selectively operable to connect the drive members to the associated output shafts.
  • the drive members are permanently connected to the associated output shafts and the clutch mechanisms are operable to selectively connect the drive members to the drive shaft.
  • each clutch mechanism includes a first portion carried by the associated drive member and a second portion which is mounted to rotate about the axis of the drive shaft and is movable longitudinally along the shaft by a clutch engagement actuator between an engaged position, in which the first and the second portions of the clutch are in engagement and the associated drive member therefore rotates with the drive shaft, and a disengaged position in which the two portions of the clutch mechanism are not in engagement.
  • each clutch mechanism may be connected to the drive shaft to rotate with it in a number of different ways but in one simple embodiment the drive shaft has a number of portions of non-circular cross section spaced apart along its length, each of which carries a respective second portion of a clutch mechanism, which has an opening formed in it whose shape corresponds to that of the associated portion of the drive shaft.
  • the complementary non-circular shape of the apertures in the second portions of the clutch mechanisms and of the portions of the drive shaft ensure that the second portions of the clutch mechanisms are keyed to and thus rotate with the drive shaft but may move longitudinally along it.
  • the drive shaft may carry the drive members and the portions of the drive shaft between the portions of non-circular cross-section may be circular, to permit rotation about them of the drive members.
  • the portions of the drive shaft around which the drive members extend could also be of non-circular shape and carry circular bearings on which the drive members are rotatably supported.
  • the transmission system includes an outer housing and that the drive members are supported for rotation by bearings which are fixed to the housing.
  • the drive shaft is preferably of constant cross-section along its entire length. It will be appreciated that in this embodiment there will be no direct or indirect contact between the drive members and the drive shaft.
  • clutch mechanisms may be of friction type, it is preferred that they are of positive engagement type.
  • Positive engagement clutches e.g. dog clutches, are not only cheaper than friction clutches but require less maintenance.
  • the clutch engagement actuator is connected to a rotary clutch shaft, which carries one or more actuating members cooperating with a respective second portion of the clutch mechanisms, each actuating member being so constructed that as the clutch shaft rotates the clutch mechanisms are engaged and disengaged sequentially.
  • a rotary clutch shaft which in practice will be parallel to the drive shaft, which carries a number of actuating members.
  • the actuating members are so shaped and engage the second portions of the clutch mechanisms or otherwise cooperate with them such that as the clutch shaft is rotated each clutch mechanism is engaged and then disengaged and the actuating members are so arranged that only one clutch mechanism is engaged at only one time.
  • Each clutch actuating member may be a continuous element in the form of a disc or it may be apertured or constituted by a bent portion of wire or thin rod of any appropriate cross-sectional shape.
  • the actuating members may be made of plastic, metal or of composite material.
  • the actuating members may take many forms but it is preferred that they are connected to the clutch shaft and extend generally radially from it and that they include a portion which is offset from the remainder of the actuating member in the direction of the axis of the clutch shaft.
  • each actuating member is resiliently deformable in the direction of the axis of the clutch shaft. This means that if the two clutch portions cannot be fully engaged initially, the actuating member will be deformed resiliently and will exert a biasing force onto the second clutch portion tending to move it into engagement with the associated first clutch portion. As soon as relative rotation of the two clutch portions commences, they will rapidly move into a position in which engagement is possible and the biasing force exerted by the actuating member will then ensure that engagement incurs immediately.
  • the number of actuating members Whilst it is possible for the number of actuating members to be equal to the number of clutch mechanisms, this is not in fact necessary and in the preferred embodiment the second portions of the clutch members of at least one pair of adjacent output units are connected together to form a clutch unit which cooperates with a single actuating member, which includes two portions which are offset in opposite directions from the remainder of the actuating member in the direction of the axis of the clutch shaft, which two portions are offset from one another in the circumferential direction of the actuating member.
  • the clutch mechanisms are of positive engagement or dog clutch type and in the preferred embodiment the first and the second portions of each clutch mechanism are of castellated construction affording projections and recesses, the projections on each portion engaging in the recesses in the other portion, when the clutch mechanism is engaged.
  • the drive members of the transmission system may take many forms and could be, for instance, spur gears or bevel gears. It is, however, preferred that they are worm gears in mesh with respective output worm gears which are connected to rotate with respective output shafts. Worm gears are preferred because of their low noise generation characteristics. A further reason why worm gears are preferred is that it is preferable for the output shafts to extend perpendicular to the drive shaft and the clutch shaft and worm gears represent a cheaper way of converting rotary drive in one direction to rotary drive in a direction at right angles thereto than using bevel gears.
  • each output worm gear may be connected to rotate with only a single output shaft, it is preferred that it is in fact connected to rotate with two respective output shafts, whereby each output unit may power two separate drive mechanisms.
  • each output unit may power two separate drive mechanisms.
  • worm or helical gears also provides the possibility of using differing gear ratios within a very compact arrangement for adjustments requiring different speeds of actuation.
  • Figure 1 is a perspective view of a transmission system in accordance with the present invention of a transmission system in accordance with the present invention, from which the outer housing has been omitted for the sake of clarity;
  • Figure 2 is a plan view of the transmission system of Figure 1;
  • Figure 3 is a vertical sectional view of the transmission system of Figures 1 and 2, additionally showing the outer housing;
  • Figures 4 and 5 are perspective views showing only a single drive gear and the associated clutch mechanism and actuating member in the disengaged and engaged positions only.
  • the transmission system includes a drive shaft 2, which is connected at each end to an input shaft 4, only one of which will be used in any particular application.
  • the drive shaft is of constant non-circular section, e.g. of hexagon shape, over its entire length.
  • Each spaced pair of bearings 5 rotatably supports a drive gear 6 of worm gear type.
  • Each worm gear 6 is thus supported for rotation about the drive shaft 2 but is not in contact with it.
  • At one end of each worm gear 6 is a sleeve 8 whose free end is castellated and thus affords a number of projections 10 extending in the actual direction, between which are recesses 12.
  • In mesh with each drive gear 6 is an output worm gear 14, which is mounted to rotate about an axis perpendicular to that of the drive shaft 2.
  • Connected to each end of each output gear 14 is a
  • Each clutch engagement unit 18 Slidably received on the portions of the drive shaft 2 situated between the two drive gears 6 on the left in Figure 1 and the two drive gears 6 on the right in Figure 1 are respective clutch engagement units 18.
  • Each clutch engagement unit affords a central aperture of hexagonal shape, which matches the hexagonal shape of the drive shaft.
  • the clutch engagement units 18 are thus constrained to rotate with the drive shaft 2.
  • Each clutch engagement unit 18 includes two spaced radially extending flanges 20, between which is defined an annular recess 22. Projecting longitudinally from the outer surface of each flange 20 is a number of axial projections 24, the shape, size and arrangement of which correspond to those of the recesses 12 formed in the end surface of the adjacent sleeve 8.
  • a clutch actuation shaft 26 Extending parallel to the drive shaft 2 is a clutch actuation shaft 26. This is connected by gearing 28 of any desired type to a clutch actuation motor 30. Carried by the clutch shaft 26 so as to rotate with it are two spaced actuating members 32. Each of these is constituted by a generally radially extending substantially circular disk, the outer portion of which includes a portion 34 which is offset from the remainder of the disk in one direction parallel to the length of the clutch shaft 26. Diametrically opposed to that offset portion 34 is a further similar offset portion 34, which is offset in the opposite longitudinal direction.
  • the two offset portions 34 on each actuating disk 32 are offset from one another by 180 degrees and the offset portions 34 on one actuating disk 32 are offset from those on the other actuating disk 32 by 90 degrees.
  • Each actuating disk 32 is made of nylon or some other tough but yet resilient material.
  • the outer edges of the two actuating disks 32 are received in the annular recess 22 of a respective clutch engagement unit 18.
  • the magnitude of the longitudinal offset of the offset portions 34 is so sized with respect to the dimensions of the clutch mechanisms that when the clutch motor 30 is actuated so as to rotate the clutch shaft 26, each clutch engagement unit 18 is moved sequentially by the offset portions 34 from a central position between the two drive gears 6 between which it is located to a position to the left and then back to the central position and then to a position to the right and then back to the central position again.
  • a drive motor (not shown) will be connected to one of the input shafts 4.
  • the drive shaft When the drive motor is actuated, the drive shaft will be caused to rotate about its axis and since the drive gears 6 are rotatably carried by bearings supported on the housing 3, the drive shaft will rotate with respect to the drive gears which will thus remain substantially stationary.
  • the output shafts 16 will be connected to respective actuators, e.g. the actuators of an adjustable vehicle seat. If it is desired to actuate one or more actuators connected to one or two of the output shafts 16 associated with one of the output gears 14, a control signal is sent to the clutch actuation motor 30 which then rotates the clutch shaft 26 to the desired angular position.
  • the clutch shaft is rotated until the offset portion 34 on the actuation disk 32 associated with the drive gear 6 reaches a position in which it has longitudinally displaced the associated clutch engagement unit towards the associated drive gear 6.
  • the clutch engagement unit 18 moves towards the associated drive gear 6, the projections 24 on one side of it move into the recesses 12 in the end of the associated sleeve 8.
  • the clutch engagement unit 18, which is of course constrained to rotate with the drive shaft 2, becomes rotationally locked with the sleeve 8 and drive gear 6 and the drive gear 6 thus begins to rotate.
  • This rotation is transmitted to the associated output gear 14 and thus to the associated output shafts 16, whereby the actuator or actuators connected to those output shafts are caused to rotate to produce the desired movement of e.g.
  • each clutch mechanism incorporates a first portion which forms part of the sleeve 8, and a second portion which falls part of a clutch engagement unit 18.
  • each clutch engagement unit 18 constitutes the second portion of two clutch mechanisms connected back to back. It would, however, also be possible for each second clutch portion to be wholly separate and in this event each second clutch portion would cooperate with a respective clutch actuation member carried by the clutch shaft 26. In the present case, this would mean that there would then be four clutch actuation members but each of them would then have only a single offset portion and not two but the offset portions on the four clutch actuation members would again be substantially equiangularly offset from one another.
  • the shaft of the clutch actuation motor 30 may conveniently carry a multi-pole ring magnet or a ring or disc with a number of magnets embedded in it co-operating with a Reed switch or Hall effect sensor or some other suitable electrical or electronic component or device capable of closing a circuit or creating an electrical signal.
  • the signals produced may be processed to calculate the angular positions of the various clutch actuating members.
  • the clutch shaft 26 may carry one or more magnets co-operating with a Reed switch or Hall effect sensor or another suitable device capable of closing a circuit or creating an electronic signal.
  • the signals produced may be processed to enable the position of the clutch shaft to be determined when the clutch actuation motor is energised.
  • clutch actuation members in the illustrated embodiment comprise disks with one or more portions of their outer periphery offset in the direction of the length of the clutch shaft, it will be appreciated that these actuation members may take many forms and all that is necessary is that they are so shaped and cooperate with the second portions of the clutch mechanisms such that rotation of the clutch shaft will result in sequential engagement of the clutch mechanisms.
