Abstract

Abstract Gear shift and clutch simulation apparatus for use in a driver trainer in which manual and automatic shift patterns are contained in a block on the gear shift column and into one of which a pin is selectively inserted in accordance with clutch position, the clutch being in a down position for manual or an up position for automatic, by a linkage connected to the clutch pedal arm is shown. A further linkage causes the manual pin to be lifted a small amount from the block, which has deeper indentations at each shift position, in response to clutch operation to provide a realistic simulation.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 118 words
A driver trainer gear shift simulation mechanism comprising: a. a gear shift lever; b. mounting means supporting said lever for movement in two degrees of freedom; c. means defining a pair of gear shift patterns corresponding to movement of the shift lever of manual and automatic transmissions; and d. at least one follower member selectively movable into mating engagement with one or the other of said patterns; e. said shift lever being rigidly connected to one of said pattern defining means and follower member to produce movement thereof in said 2 degrees of freedom in response to movement of said lever, such movement being constrained to the one of said patterns with which said follower member is engaged.
Claim 2
Dependent Claim 118 words
A driver trainer gear shift simulation mechanism comprising: a. a gear shift lever; b. mounting means supporting said lever for movement in two degrees of freedom; c. means defining a pair of gear shift patterns corresponding to movement of the shift lever of manual and automatic transmissions; and d. at least one follower member selectively movable into mating engagement with one or the other of said patterns; e. said shift lever being rigidly connected to one of said pattern defining means and follower member to produce movement thereof in said 2 degrees of freedom in response to movement of said lever, such movement being constrained to the one of said patterns with which said follower member is engaged.
Claim 3
Dependent Claim 24 words
The invention according to claim 1 wherein said pattern defining means comprises a single block of material with both of said patterns formed thereon.
Claim 4
Dependent Claim 19 words
The invention according to claim 2 wherein said block is rigidly attached to said shift lever for movement thereby.
Claim 5
Dependent Claim 24 words
The invention according to claim 1 wherein said follower mEans comprises a pair of pins, each adapted for engagement with one of said patterns.
Claim 6
Dependent Claim 39 words
The invention according to claim 4 wherein said pins are mounted on a common movable member to effect movement of one pin into engagement with its respective pattern while moving the other pin out of engagement with its pattern.
Claim 7
Dependent Claim 48 words
The invention according to claim 5 wherein said common movable member is connected to a clutch pedal in the trainer and said member is moved by movement of said pedal between operative and inoperative positions when manual and automatic transmissions, respectively, are to be simulated in the trainer.
