Manual transmission - Wikipedia

There are a number of gears fixed along the countershaft, and matching gears along the output shaft, although these are not fixed, and rotate independently of the output shaft. There are sliding dog collars, or dog clutches, between the gears on the output shaft, and to engage a gear to the shaft, the collar slides into the space between the ...

Automatic Transmissions A Short Course on How They Work ...

To shift from first to high gear, the band is released and the clutch is applied causing the output shaft to turn at the same speed as the input shaft. ... Each of the many valves in the valve body has a specific purpose and is named for that function. For example the 2-3 shift valve activates the 2nd gear to 3rd gear up-shift or the 3-2 shift ...

function of the output shaft on a gear boand

The output shaft is connected to the wheels by means of additional gears: the angular speed of the output shaft has a much wider range of possible angular speed as the gearbox is capable of changing the speed ratio, i.e. the ratio between the angular speed of the input shaft and that of the output shaft.

Differential (mechanical device) - Wikipedia

A differential is a gear train with three shafts that has the property that the rotational speed of one shaft is the average of the speeds of the others, or a fixed multiple of that average.

How the Sychronizer Works - The MGA With An Attitude

When the clutch is depressed the input shaft is free to change speed, so the input either speeds up or slows down to match speed of the output shaft, after which the mating gear and hub can engage. On the side of the freewheeling gear, after the narrow row of small teeth, there is smooth steel male cone.

Power and Torque: Understanding the Relationship Between ...

Referring to Figure 1, assume that the handle is attached to the crank-arm so that it is parallel to the supported shaft and is located at a radius of 12" from the center of the shaft.In this example, consider the shaft to be fixed to the wall. Let the arrow represent a 100 lb. force, applied in a direction perpendicular to both the handle and the crank-arm, as shown.

Techtips - GM TH350 Transmission Disassembly Guide

Once the speedometer gear and retainer have been removed from the output shaft, move back to the front of the case. Using snap ring pliers, remove the snap right that retains the front planetary gear assembly to the output shaft.

Automatic Transmissions - Learn how an automatic ...

On the transmission output shaft there is a straight spur gear that has a parking pawl that prevents the shaft from turning. When the operator selects park, the parking pawl engages and slips between two of the teeth on the parking pawl gear.

Section 5 Transfer Case - Testroete

The chain drive transfer case has a similar function to the gear drive transfer case. This type of transfer case uses a planetary gear set instead of a countershaft to provide low range gear reduction. It also ... drives the rear output shaft. In transfer case lowrange operation, the input shaft drives the sun

Transmission (mechanics) - Wikipedia

The continuously variable transmission (CVT) is a transmission in which the ratio of the rotational speeds of two shafts, as the input shaft and output shaft of a vehicle or other machine, can be varied continuously within a given range, providing an infinite number of possible ratios.
