21909007981 transmission assembly for LG956 Wheel Loader Parts
Product Description
21909007981 Transmission is composed of two main parts 1. the hydraulic Torque Converter;
2. the rear-mounted counter shaft transmission with multi-sheet friction clutch.
1).The hydraulic torque converter is a kind of hydraulic transmission component. It is an element that transfers power by means of high-speed movement of liquid. Its working characteristic is that the speed and torque at the input end are basically constant, while the speed and torque at the output end can be greater than, equal to or less than the speed and torque at the input end, and the output speed and output torque can vary with the load of the driven machine. Continuously adjust changes automatically. Because the hydraulic torque converter has the functions of stepless speed change and torque change, it is widely used as a transmission device between various power machines and working machines.
2). Manual transmission is also called mechanical transmission. It is necessary to shift the gear lever by hand to change the gear meshing position in the transmission and change the transmission ratio, so as to achieve the purpose of shifting. By shifting the shift lever, the driving gear on the intermediate shaft is switched, and the combination of gears of different sizes is combined with the power output shaft, thereby changing the torque and speed of the driving wheel. Manual transmission is mainly composed of housing, transmission components (input and output shafts, gears, synchronizers, etc.), and control components (shift levers, shift forks, etc.).
Advantages
Compared with the use of ordinary mechanical transmission, the use of hydraulic mechanical transmission has many
advantages.
1. The Machine can start smoothly, can absorb and attenuate vibration and impact, thereby improving ride and comfort.
2. It can drive stably at a very low speed to improve the passing performance of the machine on bad roads.
3. It can automatically adapt to the change of driving resistance, and carry out stepless speed change within a certain range, so as to help improve the dynamics and average speed of the car.
4. The working medium of hydraulic transmission is liquid, which can greatly reduce the dynamic load of the transmission
system,thus increasing the service life of related components and parts. This is particularly important for super-heavy dump trucks that are often under severe conditions (so many construction vehicles use hydromechanical transmissions)
5. Obviously reduce the number of shifts, facilitate the realization of automatic or semi-automatic shifts, and is simple and
labor-saving for driving operations.
6. It can prevent the Engine from stalling due to the sudden increase of external load. Packing & Delivery 
Before packaging, we generally evaluate the fragility of the goods and the value of the goods, and then select the appropriate inner packaging materials. Secondly, we consider that various situations may occur during transportation, and we have requirements for the compression, shock and water resistance of the outer packaging of the goods.
About the shipping method, Cabin usually use sea shipping methods, and the port can be specified by the customers.
