The function of transmission of 10 wheels dump truck:

Change the drive ratio, expand the drive wheel torque and speed range to meet the changing conditions of travel, while the engine in the favorable (high power and low fuel
consumption) under the conditions of work; in the engine rotation direction unchanged The use of neutral, interrupt power transmission to the engine to start, idle, and easy to shift gear or power output.

The transmission is composed of variable speed transmission mechanism and operation mechanism, if necessary, can also be installed power output device. There are two ways to classify: according to the transmission ratio change mode and according to the different ways to divide the way.

According to the transmission ratio to change the way points:
The stepless transmission is currently the most widely used. It uses a gear drive, with a number of fixed transmission ratio. According to the type of wheel used, there are two kinds of fixed-type fixed transmission (ordinary transmission) and rotary rotary transmission (planetary gear transmission). At present, cars and light and medium-sized truck transmission transmission ratio is usually 3-5 forward and a reverse gear, heavy trucks in the modular transmission, there are more stalls. The so-called transmission file
number refers to the forward gear number.
Continuously variable transmission of its transmission ratio in a certain range of values ​​can be infinitely many levels of change, common with electric and hydraulic (moving liquid) two. The variable speed drive part of the electric type continuously variable transmission is a DC string motor, which is widely used in the super heavy duty dump truck drive train, except for the application of the trolleybus. The transmission parts of the moving fluid type continuously variable transmission are hydraulic torque converter.
Integrated transmission refers to the hydraulic torque converter and gear type transmission composed of hydraulic mechanical transmission, the transmission ratio can be between
the maximum and minimum in the range of several intermittent changes, the current More applications.

By way of manipulation: (HOWO 12 wheels heavy duty dump truck for sale)
The forcedly operated transmission is operated by the driver directly to the shift lever.
Automatic transmission of the transmission ratio selection and shift is automatically carried out, the so-called "automatic" refers to the mechanical transmission of each gear
conversion is to reflect the engine load and speed of the signal system to control the transmission system components To achieve. The driver only needs to manipulate the
accelerator pedal to control the speed.
There are two types of semi-automatic transmission: one is commonly used in several stalls automatically manipulated, the rest of the stalls by the driver; the other is pre-selected, that is, the driver with the button to select the stalls, When the clutch pedal is released or the accelerator pedal is released, an electromagnetic device or hydraulic device is switched on for gearshift.
