摘要:
The lever comprises a trigger (10) that retracts upon contact with a stop (12) in order to shift from reverse, said lever (1) being secured to means in order to be switched from a position that allows the shift and the selection of gears to another position for actuating the parking brake with the possibility of selecting and shifting gears. The base of the lever comprises a spherical body (2) mounted such that it can move in multiple directions in a supporting member (3) and arranged for the shifting and selection of gears.

The gear change arrangement has a gear change lever (1) and a mechanism (4-9) for transferring the selection movement to the gearbox. The gear lever can be moved in an automatic gear change gate for selecting automatic gear stages and in a sequential change gate for manually changing up and down. The gear change arrangement has three adjacent, pref. essentially mutually parallel movement areas, each two adjacent movement areas being provided for different functions

A control unit for the gear or shift program selection of an automatic transmission of a motor vehicle is presented, which has a emergency release mechanism. With this a parking brake of the motor vehicle transmission can be released by an operating device that can be actuated by the driver. A housing (3) is provided and a selector lever (1), which can be brought into at least two end positions, in which control unit the operating device of the emergency release mechanism is an integral part of the control unit, and in which the operating device has a detachable stop element (7). The stop element (7) is secured in a mount (9) of the control unit by means of a coded release mechanism (15) and acts as a movement limitation for the release movement of the parking brake by the operating device of the emergency release mechanism in the non-actuated state. The emergency release mechanism can also be actuated due to this novel design even with the control unit only, and, moreover, increased requirements on theft protection can be met.
摘要:
A selector mechanism for a vehicle transmission comprising an automatic transmission coupled to a range-change transmission having first and second ranges includes a ratio selector lever movable along three paths defined by an H-shaped gaze. The first path is defined by a first limb of the gate for shift selection in the automatic transmission with the first range of the range-change transmission selected. The second path is defined by a second limb of the gate substantially parallel with the first limb for shift selection in the automatic transmission with the second range of the range-change transmission selected and the third, transverse, path is defined by a limb of the gate transverse to the first and second limbs. Movement of the selector lever along the transverse path effects a change from one range to the other in the range-change transmission.

A compound transmission (10) comprising a main transmission section (12) connected in series with a range type multiple speed auxiliary drive train unit (14) having at least two selectable range type ratios, and a combined shift control unit (56) therefor, is provided.
摘要:
A fluid pressure actuated auxiliary transmission section (14) shift control system (230)/method is provided which includes control members (246, 328) to prevent auxiliary section synchronized clutch (92, 128) damage if the main transmission section (12) is engaged during an auxiliary section shift. A range interlock assembly (258) is provided which will release the range slave valve (238) as the main transmission section is shifted toward the neutral position thereof.

Le dispositif de commande d'une transmission composite ayant une boîte de vitesses principale (1) et une boîte de vitesses auxiliaire (2) à deux gammes ayant une gamme supérieure et une gamme inférieure. Ce dispositif comporte quatre coulisseaux, le quatrième coulisseau (37) est destiné à engager la gamme inférieure et la gamme supérieure de la boîte de vitesses auxiliaire (2) à deux gammes. Un mécanisme (51) est prévu pour le déplacement du quatrième coulisseau (37) en position de la gamme inférieure lors du déplacement du troisième coulisseau (36) du point mort en position d'engagement sous l'action d'un élément d'entraînement (38). Ce dispositif s'applique par exemple, aux transmissions de véhicule de transport tel qu'un camion.
摘要:
A snift control for change speed gear transmission for vehicles having a main transmission and a two-section group transmission provides two sets of shift paths for a gear change lever one for each section of the group transmission, and individual positions in each shift path set for selecting individual ratios in the main transmission. The control comprises parallel axially slidable shift rods (11, 12 and 13) and a cross shaft (14) which is axially and rotationally movable. The shift rods present exially spaced pairs of faces (16a, 16b, 17a, 17b and 18a) for selective engagement by a selector finger (15) carried by the cross shaft. One pair of faces (16b and 17a) on each shift rod (11 and 12) is disposed between the two pairs of faces (16a, 16b and 17a, 17b) on the other shift rod (12 and 11). A switch (not shown) is operable by the cross shaft to shift the group transmission as a result of movement of the gear change lever from one set of shift paths to the other and a resilient detent (62) is provided in the path of a formation (52) on the cross shaft to inform the driver when a group transmission change is effected. Furthermore, spring abutments (55, 56) position the formation (52) against the detent (62) in the neutral position of the gear change lever. In this fashion, a "double-H" pattern of shift control is achieved using a single lever having predictable neutral positions each side of a range change "gate" and a unique position to select each vehicle drive ratio in high and low range.
