Rererring now to the drawings in detail, wherein like reference characters indicate like parts throughout the several figures, the reference numeral 10 indicates generally a shock absorber unit for motor vehicles con~ ' `
structed in accordance with the invention. ~ ~ `
The shock ab.sorber unit 10 includes a channel shaped base member 11 which is adapted to be secured to the frame of a motor vehicle in any desired manner. A generally rectangular housing 12 is secured to the base member 11 and extends upwardly therefrom. A shaft 13 is journalled in the front wall 14 of the housing 12 at one end and in the rear wall 15 at its opposite end.
A shaft 16 is arranged parallel to the shaft 13 and is similarly ~ournalled ,~. - .
in the front wall 14 and rear wall 15. A shaft 17 is journalled in the ront wall 14 and in a block 18 secured to the bottom wall 19 of the housing 12.
The housing 12 has a top wall 20 secured by studs 21 to the side walls 22,`23 of the housing 12. A rectangular opening 24 extends through the top wall 21 adjacent the rear wall 15 and a rectangular opening 25 extends through the bottom wall 19 and the channel 11 adjacent the rear wall 15 in aligned relation to the opening 24.
A generally rectangular rack bar 26 having rack teeth 27 on one side thereof and rack teeth 28 on the opposite side thereof, is mounted for vertical reciprocation through the opening 24, 25 as can be clearly seen in Figures 3 and 4. An upright slot 29 is formed in the forward face of the rack bar 26 and engages over a tongue 30 on the block 18 in the housing 12.
A gear 31 is keyed for the shaft 13 and meshes with the rack teeth 27 on the bar 26. A second gear 32 is keyed to the shaft 16 and meshes with the rack teeth 2B oI' the bar 26. A gear 33 is journalled on the shaft 13 and is secured to one-way clutch element 34 also journalled on the shaft 13.
A second one-way alutch element 35 i5 keyed to the shaft 13 and is held in engagement with the one-way clu1,ch element 34 by means of a coil spring 36 encompassing the shaft 13 and extending between the gear 31 and the one-way clutch element 35. ~387~4 A gear 37 is ~o~rnalled on the shaft 16 and is rigidly secured to a one-way clutch element 38 also journalled on the shaft 16. A one-way clutch element 39 is keyed to the shaft 16 and is held in engagement with the one-way clutch element 38 by means of a coil spring 40 encompassing the shaft 16 and extending between the gear 32 and the one-way clutch element 39. The one-way clutch elements 35, 39 ars mounted for endwise sliding movement on the shafts 13, 16 respectively~ -A gear 41 is secured to the shaft 17 intermediate the gears 33, 37 and meshing with the gears 33, 37 to be driven thereby. A shaft 42 is rigidly mounted to the base member 11 and a second shaft 43 is also rigidly mounted to the base 11 in parallel relation to the shafts 42 and 17. A relatively large spur gear 44 is fixed to the shaft 17 and meshes with a relatively small spur gear 45 journalled on the sha~t 42 and rigidly secured to a relatively large spur gear 46. A relatively small spur gear ~7 is journalled on the shaft 43 and meshes with the spur gear 46. A double V-pulléy 48 is fixed to the spur gear 47 to revolve therewith.
An alternator 49 is mounted on the base member ll and is driven by a belt 50 extending from the double V-pulley 48. A second alternator 51 is ZO mounted on the base member 11 and is driven by a V-belt 52 extending from the double V-pulley 48.
In the use and operation of the invention the unit 10 is secured to the frame of a motor vehicle in any desired manner with the lower end of the rack bar 26 connected to vertically moveable portions of the running gear in the manner of connecting conventional shock absorbers. As the motor vehicle mwve~ over the earth~ surface the running gear vertically reciprocates and thus causes the rack bar to reciprocate with respect to the housing 12. As the rack bar reciprocate~ the rack teeth 27 rotate the spur gear 21 and the rack teeth 28 rotate the spux gear 32. As the rack bar moves downwardly with respect to the hou~ing 12, the gear 31 as seen in Figure 4 rotates in a ~ 3~77~
clockwise direction to thus rotate the one-way clutch element 35 in a clockwise direction driving the one-way clutch element 34 and the gear 33 in a clockwise direction so as to turn the shaft 17 in a counter clockwise direction. As the rack bar 26 reverses its diraction and moves upwardly with respect to the housing 12. The one-way clutch elements 34, 35 slip by each other 50 that no drive occurs to the gear 33. The gear 32 is then rotated in a clockwise direction and through the one-way clutch elements 38, 39 rotates the gear 37 in a clockwise direction to thus rotate the shaft 17 in a countér clockwise direction. The one-way elements 38, 39 slip by each other when the gear 32 is rotated in a counter clockwlse direction during downward movement of the rack bar 26 with respect to the housing 12.
The shaft 17 is thus rotated solely in a counter clockwise direction by alternate driving connections to opposite sides of the rack bar 26. The gears 44, 45, 46 and 47 provide a relatively high speed drive for the alter-`nators 49, 51. The driving of the alternators 49, 51 produces a drag on the movement of the raak bar 26 sufficient so that the rack bar 26 has a shock absorbing effect on movements of the running gear of the motor vehicle on which the unit 10 is mounted.
- Having thus described the preferred embodiment of the invention it shou~d be understood that numerous structural modifications and adaptations may be resorted to without departing from the spirit of the invention.

in the front wall 14 and rear wall 15. A shaft 17 is journalled in the ront wall 14 and in a block 18 secured to the bottom wall 19 of the housing 12.
The housing 12 has a top wall 20 secured by studs 21 to the side walls 22,`23 of the housing 12. A rectangular opening 24 extends through the top wall 21 adjacent the rear wall 15 and a rectangular opening 25 extends through the bottom wall 19 and the channel 11 adjacent the rear wall 15 in aligned relation to the opening 24.
A generally rectangular rack bar 26 having rack teeth 27 on one side thereof and rack teeth 28 on the opposite side thereof, is mounted for vertical reciprocation through the opening 24, 25 as can be clearly seen in Figures 3 and 4. An upright slot 29 is formed in the forward face of the rack bar 26 and engages over a tongue 30 on the block 18 in the housing 12.
A gear 31 is keyed for the shaft 13 and meshes with the rack teeth 27 on the bar 26. A second gear 32 is keyed to the shaft 16 and meshes with the rack teeth 2B oI' the bar 26. A gear 33 is journalled on the shaft 13 and is secured to one-way clutch element 34 also journalled on the shaft 13.
A second one-way alutch element 35 i5 keyed to the shaft 13 and is held in engagement with the one-way clu1,ch element 34 by means of a coil spring 36 encompassing the shaft 13 and extending between the gear 31 and the one-way clutch element 35. ~387~4 A gear 37 is ~o~rnalled on the shaft 16 and is rigidly secured to a one-way clutch element 38 also journalled on the shaft 16.

The one-way clutch elements 35, 39 ars mounted for endwise sliding movement on the shafts 13, 16 respectively~ -A gear 41 is secured to the shaft 17 intermediate the gears 33, 37 and meshing with the gears 33, 37 to be driven thereby. A shaft 42 is rigidly mounted to the base member 11 and a second shaft 43 is also rigidly mounted to the base 11 in parallel relation to the shafts 42 and 17. A relatively large spur gear 44 is fixed to the shaft 17 and meshes with a relatively small spur gear 45 journalled on the sha~t 42 and rigidly secured to a relatively large spur gear 46. A relatively small spur gear ~7 is journalled on the shaft 43 and meshes with the spur gear 46. A double V-pulléy 48 is fixed to the spur gear 47 to revolve therewith.
An alternator 49 is mounted on the base member ll and is driven by a belt 50 extending from the double V-pulley 48. A second alternator 51 is ZO mounted on the base member 11 and is driven by a V-belt 52 extending from the double V-pulley 48.
In the use and operation of the invention the unit 10 is secured to the frame of a motor vehicle in any desired manner with the lower end of the rack bar 26 connected to vertically moveable portions of the running gear in the manner of connecting conventional shock absorbers. As the motor vehicle mwve~ over the earth~ surface the running gear vertically reciprocates and thus causes the rack bar to reciprocate with respect to the housing 12. As the rack bar reciprocate~ the rack teeth 27 rotate the spur gear 21 and the rack teeth 28 rotate the spux gear 32. As the rack bar moves downwardly with respect to the hou~ing 12, the gear 31 as seen in Figure 4 rotates in a ~ 3~77~
clockwise direction to thus rotate the one-way clutch element 35 in a clockwise direction driving the one-way clutch element 34 and the gear 33 in a clockwise direction so as to turn the shaft 17 in a counter clockwise direction. As the rack bar 26 reverses its diraction and moves upwardly with respect to the housing 12. The one-way clutch elements 34, 35 slip by each other 50 that no drive occurs to the gear 33. The gear 32 is then rotated in a clockwise direction and through the one-way clutch elements 38, 39 rotates the gear 37 in a clockwise direction to thus rotate the shaft 17 in a countér clockwise direction. The one-way elements 38, 39 slip by each other when the gear 32 is rotated in a counter clockwlse direction during downward movement of the rack bar 26 with respect to the housing 12.
The shaft 17 is thus rotated solely in a counter clockwise direction by alternate driving connections to opposite sides of the rack bar 26. The gears 44, 45, 46 and 47 provide a relatively high speed drive for the alter-`nators 49, 51. The driving of the alternators 49, 51 produces a drag on the movement of the raak bar 26 sufficient so that the rack bar 26 has a shock absorbing effect on movements of the running gear of the motor vehicle on which the unit 10 is mounted.
- Having thus described the preferred embodiment of the invention it shou~d be understood that numerous structural modifications and adaptations may be resorted to without departing from the spirit of the invention.
