6 Claims. (Cl. 11518) boat.
Heretofore, shock mountings have been developed for cushioning the torque vibration of the power head and propeller unit from the transom bracket and boat. Such mountings, however, do not prevent other types of vibration from being transmitted to the transom bracket and boat. Applicants invention provides a novel and improved means for resiliently suspending the outboard motor unit comprising the power head, drive shaft and lower unit to vibrationally isolate the outboard motor unit from the supporting bracket and boat.
It is therefore an object of the present invention to suspend or float an outboard motor unit for freedom from torque vibration without transmitting any of such vibrations to the supporting bracket or boat and without in any way interfering with the perfect control of the pivotal steering movement of such motor.
Another object of the invention is to provide novel means for resiliently suspending the outboard motor unit within a supporting member. 7
Another object of the invention is the provision of novel resilient means of simple construction requiring fewer parts and less machining than prior known means for vibrationally isolating the outboard motor unit from the boat and supporting member.
Another object of the invention is to provide a resiliently suspended outboard motor unit in which the dynamic forces developed thereby are resisted primarily by the supporting resilient means.
Another object of the invention is the provision of novel resilient means for supporting the outboard motor unit wherein impact resulting from the outboard motor propeller striking an obstruction is absorbed by said resilient means.
Objects and advantages other than those set forth above will be apparent from the following description when read in connection with the accompanying drawing, in which:
Fig. l is a side elevation view shown partially in section of an outboard motor embodying the invention;
Fig. 2 is a side elevation view of a part of an outboard motor embodying the invention;
Fig. 3 is a front view of the structure shown in Fig. 2;
Fig. 4 is a section view taken along line 4-4 of Fig. 2;
Fig. 5 is a view shown partially in plan and partially in section taken along line 55 of Fig. 3;
Fig. 6 is an enlarged section view taken along line 6-6 of Fig. 4; and
Fig. 7 is a side elevation view of an outboard motor embodying the invention showing a force diagram of thrust forces acting thereon.
As shown in the drawings, a preferred embodiment of the invention is illustrated as applied to'an outboard motor ice 1 comprising a hollow drive shaft housing 2 for enclosing a drive shaft 5, a gear housing 3 or lower unit connected to the drive shaft housing 2 and-carrying a propeller 4 at the lower end thereof, and attachment means 6 for attaching the outboard motor 1 pendently to the transom 7 of a boat, not shown. The vertical drive shaft 5 may be considered to be at or near to the center of gravity of the outboard motor unit, although in some cases the center of gravity may be rearwardly of the shaft.
The attachment means 6 or support member comprises a clamp bracket 8 having a generally L-shaped swivel bracket 9 pivotably connected thereto by means of a bolt 11 for pivotal movement in a vertical plane. Theclamp bracket 8 is shown as a substantially U-shaped clamp adapted to engage over the upper edge of the transom 7 and carrying a clampingscrew 12 at the lower end thereof for engaging the inside of the transom '7 to clamp the transom 7 between the end of thescrew 12 and a portionof the clamp bracket 8. The swivel bracket 9 includes a vertically extending bushing 13 in register with openings 14 provided in the upper and lower bifurcated members 18, 19 which together with the connecting hollow pivot pin 17 comprise a yoke'member 16 forming a part of the support member. The yoke member is pivotably connected to the swivel bracket for movement in a horizontal plane with the hollow pivot pin 17 passing through bushing 13. The pin 17 isconnected to the members 18, 19 by means of a press fit 'to'solidly join the up per and lower members 18, 19. A pair of laterally spaced bolts 20 as shown in Fig. 4' pass through fore and aft horizontally extending openings '21 in the lower member 19 while a pair of laterally spaced studs 22 as shown in Fig. 5 parallel the bolts 20 and engage tapped openings in the upper member'l-S to-cornplete the yoke member 16.
The drive shaft housing 2 as shown inFig. 1 comprises a hollow cast memberhaving an upper flared region 23, an intermediate convergent region 24, and a lower portion 26 which extends outwardly, both forwardly and rearwardly. The drive shafthousing 2 is provided with a streamlined rear portion 27 as shown in Fig. 4 to reduce the resistance of the housing 2 while.moving through water, and the front portion 28 of the housing 2 opposite from yoke member 16 is substantially planar.
The drive shaft housing 2 is attached and spaced from the yoke member 16 by means of resilient members comprising annular rubber members 29 as shown in Figs. 4, 5 and 6. The resilient members 29 are each provided with inner and outer annular vmetal cylinders 31, 32 bonded thereto as shown in Fig. 6. .The inner metal cylinder 31 is mounted on a corresponding finger projecting from yoke member 16, here illustrated as a bolt 20 or stud 22 and the outer metal cylinder 32, in the case of the lower member 19, is seated within an annular groove 33 provided in recess 34 of the housing 2. YA metal cap 35 of semi-circular cross section is secured to the housing 2 by means of screws 36 and together with recess 34 forms a cavity within which the resilient member 29 is disposed. In the case of the upper member 18, the outer metal cylinder 32 of the resilient member 29 is seated within an annular groove 37 formed by a splithollow cylindrical member 38 which is secured to the drive shaft housing 2 by means of bolts 39 passing therethrough and engaging threaded openings, not shown, in the housing 2. The inner metal cylinders 31 of the rubber members 29 are secured to the lower member 19 between the heads of'the respective bolts 20 and the member19 by means of nuts 41. In the upper member 18 the inner metal portions 31 are secured between the member 18 and respective nuts 42 threaded on the studs 22. Interposed between the nuts 42 and the resilient members 29 of the upper member 18 are resilient cushion rings 43 adapted to engage a A power head 45 as shown inFig. l', the drive shaft .housing2 upon which the power head 45 is mounted, and the lower unit or gear housing 3 form an outboard motor unit that is completely supported by the yoke member 16 of the attachment means 6 by means of the resilient members 29. Therefore, the weight of this outboard motor unit, the forces developed by the'action of the power head 45 and the thrust developed by the propeller 4 are resisted bythe vertically spaced resilient members 29.
In order to permit substantially complete freedom of movement of the outboard motor unit relative to the yoke member 16, a flexible shift control rod 46 as shown in ,Fig. l is provided passing through the pivot pin 17 to connect the shift control 47 carried by the power head 45 to the portion of the shift control 48 carried by the gear housing 3.
The proper positioning and dimensioning of the resilient members 29 may be readily calculated by resorting to a force-moment diagram as shown in Fig. 7. Assuming that the maximum propeller thrust F acting through the point C is 100 pounds and the lower resilient member 29 is positioned at B so that the distance S be tween the upper resilient member 29 positioned at A and the lower member at B is equal to the distance S between the lower member at B and the point C, the forces F and F may be computed as follows:
Taking force'moments about the point B:
Where the center of gravity of the outboard motor unit is to the rear of the resilient members 29, the weight of the motor will generally add to the forces referred to above. It is, therefore, desirable to dispose the resilient members on opposite sides of the center of gravity with at least some part of the members in the transverse plane containing the centerof gravity; Intheillustrations, it will be noted that the members 29 are disposed laterally of the drive shaft 5, whichin this instance isvery close to the vertical transverse plane of the center of gravity,
Although only one embodiment has been illustrated and described, it will be apparent to those skilled in the art that various changes and modifications may be made therein without departing from the spirit of the'invention or from the scope of the appended claims.
