The Transmission in a Ferret
The transmission in a Ferret In the Ferret transmissive power from the engine is taken through a fluid flywheel to a five speed pre-selector gearbox. At the front of, and forming a single unit with the gearbox, is a transfer box which contains a forward and reverse mechanism and a differential drive: the H-drive. An H-drive drivetrain is used for heavy off-road vehicles to supply power to each wheel. H-drives do not use axles but rather individual wheel stations. A transfer case is a part of the drivetrain of four-wheel-drive, in other words: a vehicle with multiply-powered axles. With a permanent 4x4 drive there is no ‘diff' action between the front wheels and rear wheels on either side. Therefore, the only disadvantage of the H-differential configuration is wind-up. A single differential splits the drive into separate left and right drive shafts. At each wheel station a bevel box drives the half-shaft out to the wheel. Effectively, a longitudinal diff lock is permanently engaged in a vehicle with an H- drive. The advantages of the H-differential are: Independent suspension at each wheel station Traction is maintained if one wheel loses grip Greater ground clearance and lower unsprung mass (no centre diff box on the axle). A low unsprung mass (i.e. the suspension, wheels/tracks and other components directly connected to the suspension) leads to better ride & handling and less vibration. The upper half of the Ferret transfer box contains two spiral bevel directional control gears, in constant mesh with the driving bevel on the output shaft of the gearbox. -

This torque-assist mechanism becomes a torque transfer path during gearshifts, in order to overcome a typical dynamic problem of the AMTs, that is the driving force interruption. The mean power contributions during gearshifts are computed for different engine and ACL interventions, thus allowing to draw considerations useful for developing the control algorithms. The simulation results prove the advantages in terms of gearshift quality and ride comfort of the analysed transmission. -
Jeep Cherokee XJ Grand ZJ 1 Inch and 1.5 Inch Transfer Case
PRODUCT INSTRUCTIONS Jeep Cherokee XJ Grand ZJ 1 Inch and 1.5 Inch Transfer Case INSTRUCTIONS - Read complete instructions before beginning installation, the following special tools are recommended: Coil spring compressor, floor jack, jack stands, and hand tools. 1. Park the vehicle on a flat level surface and block the front and rear tires. Place the transmission in neutral. 2. Loosen all of the engine mount bolts ½ turn. 3. Support the transfer case cross member with a transmission floor jack. Remove the 2 bolts, 2 nuts and 2 studs from each side of the cross member. 4. Slowly lower the cross member 1 1/8 inches to allow enough room to install the new tube or bar spacers. 5. Place the spacers supplied in this kit between the frame and cross member so that the edge of the spacers are nearly flush with the ends of the cross member and be sure that all the mounting holes are lined up. 6. Slowly raise the jack up to firmly hold the spacers in place. Using the new bolts supplied with this kit place a lock washer (if supplied) on the bolt first then the flat washer second. With everything in position place a drop of thread lock (not supplied) on the threads of each bolt in the kit. Insert the new bolts and torque to 33 foot lbs. Remove the transmission jack and set aside. 7. Re-torque the engine mount bolts loosened in step 4. The engines mount to block bolts torque to 45 foot lbs. The engines mount to frame bolts torque to 30 foot lbs. -

The article presents the results of a comparative tests and mathematical modeling for the selection of various units and assemblies of motor vehicles. These results were analyzed for optimal power plant and transmission selection, followed by improvements to develop a vehicle with an up to date electromechanical transmission. The article substantiates the choice of components and assemblies for a 4x4 ATV with an electromechanical transmission. 1 Description of the developed all-terrain vehicle (ATV) Many works have been devoted to the creation of the technical appearance of all-terrain vehicles and the selection of its components. [1-17] Currently, there is a tendency to switch to environmentally friendly alternative methods of generating electrical energy, one of which is the electric motor. Unfortunately, now, ATVs with an electric motor are inferior to ATVs with internal combustion engines in terms of various performance characteristics. Although the former have a number of advantages over the latter: the absence of emissions, which makes it possible to improve the ecological state of the planet, and an almost silent operation mode, which makes it possible to use them during special operations, as well as for walks in natural protected areas. As a rule, during development work, it is necessary to make changes in the design of the mechanical part of the transmission, i.e. -

MANUAL TRANSMISSION SERVICE Introduction
MANUAL TRANSMISSION SERVICE Introduction Internal combustion engines develop very little torque or power at low rpm. This is especially obvious when you try to start out in direct drive, 4th gear in a 4-speed or 5th gear in a 6-speed manual transmission -- the engine stalls because it is not producing enough torque to move the load. Manual transmissions have long been used as a method for varying the relationship between the speed of the engine and the speed of the wheels. Varying gear ratios inside the transmission allow the correct amount of engine power to reach the drive wheels at different engine speeds. This enables engines to operate within their power band. A transmission has a gearbox containing a set of gears, which act as torque multipliers to increase the twisting force on the driveshaft, creating a "mechanical advantage", which gets the vehicle moving. From the basic 4 and 5-speed manual transmission used in early Nissan and Infiniti vehicles, to the state-of-the-art, high-tech six speed transmission used today, the principles of a manual gearbox are the same. The driver manually shifts from gear to gear, changing the mechanical advantage to meet the vehicles needs. Nissan and Infiniti vehicles use the constant-mesh type manual transmission. This means the mainshaft gears are in constant mesh with the counter gears. This is possible because the gears on the mainshaft are not splined/locked to the shaft. They are free to rotate on the shaft. With a constant-mesh gearbox, the main drive gear, counter gear and all mainshaft gears are always turning, even when the transmission is in neutral.
