The range box also selected reverse giving 6 reverse gears with speeds similar to medium in forwards. All gear changes were made with the use of a dry clutch. This gearbox then had a 2-speed powershift section added after the dry clutch and before the 6-speed gearbox. This resulted in 36 forward gears (2×6×3) and 12 reverse (2×6×1).
In 1991, the firm entered a joint venture with Sumitomo of Japan to produce excavators, which ended in 1998. [7] Two years later, a JCB factory was completed in Pooler near Savannah, Georgia, in the US, and in 2012 a factory was opened in Brazil. [8] In 2005, JCB bought a company, purchasing the German equipment firm Vibromax.
In some cases, including the Honda Gold Wing and BMW K1200LT, this is not really a reverse gear, but a feature of the starter motor which when reversed, performs the same function. To avoid accidental operation, the reverse is often engaged using an entirely separate control switch - e.g., a pull-toggle at the head of the fuel tank - when the ...
Typically the multi-plate clutches are arranged on the main shaft or on the counter shaft. The forward reverse section of the gear box is generally located in the forward section as close to the engine as possible. This is beneficial to the forward reverse control elements as they are not subjected to the high relative torque.
Performing a three-point turn (shown for right-hand traffic). The three-point turn (sometimes called a Y-turn, K-turn, or broken U-turn) is the standard method of turning a vehicle around to face the opposite direction in a limited space, using forward and reverse gears.
For reverse gear, an idler gear is used to reverse the direction in which the output shaft rotates. In many transmissions, the input and output shafts can be directly locked together (bypassing the countershaft) to create a 1:1 gear ratio which is referred to as direct-drive .
[7] [8] The Baldwin Locomotive Works used the Ragonnet reversing gear, and other US builders generally abandoned positive locking features sooner than later. Many American locomotives were built, or retro-fitted, with power reversers, including the PRR K4s , PRR N1s , PRR B6 , and PRR L1s , but in Britain locking cylinders remained in use.
