摘要:
A transfer case (10) includes an input shaft (12), first and second output shafts (14, 16) and a planetary gearset (18) having a sun gear (74), a ring gear (70), a carrier (84, 90) and a pinion gear (78) meshingly engaged with the sun and ring gears. A range actuator (20) includes first, second and third range sleeves (22, 24, 26) abutted in series being axially translatable between a first position (H) to provide a drive connection between the input shaft (12) and the first output shaft (14), a second position (HL) providing a direct drive ratio connection between the input shaft (12) and the first output shaft (14) as well as the input shaft (12) and a second output shaft (16), and a third position (L) to provide a reduced speed drive ratio connection between the input shaft (12) and the first output shaft (14) as well as the input shaft (12) and the second output shaft (16). The gears of the planetary gearset (18) are not driven when the range sleeves are at the first and second positions.
摘要:
An arrangement structure of a shifting actuator of an internal combustion engine mounted on a motorcycle is provided in which while the shifting actuator is provided externally of an engine case of the engine so as not to interfere with auxiliaries, it is protected without external protrusion and external appearance is kept satisfactory. An external wall of an engine case is partially inwardly recessed to form a recessed portion capable of accommodating a shifting actuator. An actuator body of the shifting actuator is disposed in the recessed portion. An attachment bracket attached to an end portion of the actuator body is fitted to a first fitting hole of an engine case outer lateral wall on the side of the recessed portion and is secured to the engine case outer wall. The motorcycle has a multistage transmission that can reduce its axial width to achieve compactness.
摘要:
A shift drive mechanism for a multi-speed transmission in which a shift rod can be stably maintained at a desired fixed position without the need for an intermittent drive mechanism and which is small in size and low in cost. The shift drive mechanism for a multi-speed transmission includes a shift guide groove G formed in a shift drum so as to guide a shift pin moved in the axial direction together with the shift rod. Each of gear speed groove portions Gs is formed at axial-direction positions determined on a gear speed basis and directing the shift pin only to the circumferential direction or not moving the shift pin in the axial direction attendant on turning of the shift drum is set to be longer than the distance the shift drum travels idly from the moment of stop of driving of a shift actuator.

摘要:
The invention concerns an automated gear drive, comprising two main gearshafts (18, 20) bearing drive pinions (22, 24) and linked each by a clutch (E1, E2) to a clutch shaft (10), a gearbox output shaft (12) bearing driven pinions (26) each of which is associated with one-way locking means (28) controlled to be selectively interlocked with the gearbox output shaft (12), said means (28) being controlled by mechanical means (30, 32, 34) common to all the loose pinions (26) of the different gear ratios. The invention enables in particular gear ratio shift with uninterrupted torque transmission to the gearbox output shaft (12).
摘要:
A vehicle transfer case shifter system including a shifter mechanism with a cable actuator for actuating the pivot arm of a transfer case. The shifter mechanism includes two plates, one connected to the shifter handle and the other to the cable. The one plate is vertically slidable relative to the other plate and uniquely coupled to the other plate.
摘要:
A device for operating a transmission for a four-wheel drive vehicle, the power transmission system of which is selectively changed to two-wheel driving. The power transmission system selectively provides a two-wheel drive, a high range four-wheel drive and a lower range four-wheel drive via movement of a shift lever. The shift lever has a shift movement pattern which laterally changes direction at an intermediate position, such that the shift lever cannot be shifted from one end position to the other end position without passing the lateral direction change.
摘要:
A transmission shift mechanism having straight line movement. The shift control operates a single shift rail carrying two shift forks to provide three speeds and a neutral position.
摘要:
Controls for transfer case gearing in which a manual lever is moved in a straight path to predetermined stations operating a pair of shift rods, connected by interlock pins and cam surfaces, to condition transfer case gearing for four wheel high, two wheel high, neutral and four wheel low drive.
