Abstract:
The invention relates to a gear change control device(1) for a vehicle, comprising a spring-loaded gearshift(5) which runs in guide grooves (3) which are provided in a bottom plate (2) and define the gear change pattern and gear change resistance of the gearshift(5) when the driver moves the gear lever between different gear positions (9). The invention is achieved by at least one pin (6) being arranged to be movable in a recess or channel(8) in the bottom plate (2), by the pin (6) being arranged to be movable between different positions, from at least an inactive state to an active state, by the pin (6) being lockable/blockable in the active state and/or the inactive state, and by the pin (6) in one state being adapted to allowing engagement of a certain gear position(9) or preventing disengagement from a certain gear position(9).
Abstract:
A safety device for a mechanical gearbox, comprising a gear lever-operated internal control shaft (2) translatable to select a gear change line, and rotatable to engage a gear on the selected line, a gear change pin (3) secured to the internal control shaft (2), a set of dogs (6a, 6b, 6c, 6d) including at least one special forward gear dog (6c) and a reverse gear dog (6d), said dogs being adjacent and moved on either side of their neutral line and in opposite directions to engage the highest forward gear and the reverse gear, respectively. Said device includes means for guiding the gear change pin (3) in such a way as to prevent insertion thereof into the reverse gear dog (6d) when the special forward gear dog (6c) is realigned with the other forward gear dogs (6a, 6b).
Abstract:
An exemplary shifter may include a lever, at least a portion of which may extend along an axis. The lever may be movable along the axis from and to a neutral position. The exemplary shifter may also include a spring operatively attached to the lever. The spring may be configured to bias the lever to the neutral position. The exemplary shifter further may include a lever control assembly to substantially inhibit the lever from rotating about the axis. The lever control assembly generally may remain stationary with respect to the axial movement of the lever. The lever control assembly may include a bushing around at least a portion of the lever, and through which the lever is slidable in the axial direction. The lever control assembly may also include a first pair of pins and a second pair of pins, which may form a cross joint around the bushing.
Abstract:
An exemplary transmission may have a reverse shift rail and a locking mechanism to ensure that the reverse shift rail stops in a neutral position when disengaging from the other gear range. The reverse shift rail may be configured to move axially in a first direction to place the transmission in a drive gear, and in a second direction for a reverse gear. The transmission may also include a rail selector configured to engage with the reverse shift rail, and a reverse inhibitor configured to selectively dampen the reverse shift rail from moving in the second direction. An exemplary locking mechanism may include a main body and an arm extending from the main body. When the reverse shift rail disengages from the drive gear, the arm may be configured to contact the reverse inhibitor to substantially inhibit the movement of the reverse shift rail in the second direction.
Abstract:
L'élément (4) est monté pivotant par rapport à un axe (5) et assujetti à un doigt de sélection (3) solidaire du levier pour provoquer le pivotement de l'élément (4) sous un effet de basculement angulaire. Il comprend, au niveau de l'axe de pivotement (5) dudit élément (4), un profil en came (6) que présente une partie dudit élément (4), ledit profil (6) coopérant avec un organe élastique de rappel (7) pour créer, en fonction du positionnement angulaire de l'élément de sélection et de la zone considérée du profil en came, une résistance d'intensité variable jusqu'à créer un point dur correspondant à la sélection de la marche arrière
