04120-21933 V-BELT
The V-belt is a key flexible component in the transmission system of bulldozers, named after its trapezoidal cross-section. It is mainly composed of a strong layer (such as polyester wire rope, steel wire rope), a stretching layer (rubber or polyurethane), a compression layer (wear-resistant rubber), and a wrapping layer (sail cloth). Its core function is to transmit engine power to auxiliary equipment such as fans, water pumps, and generators through friction, while absorbing shocks and vibrations during the transmission process, ensuring the stable operation of the entire auxiliary system
Typical application scenarios of V-belt in bulldozers
Choose the plan that suits you best.
The cooling fan is driven by a V-belt to control the engine water temperature (normal operating temperature of 80 ℃~95 ℃), avoiding power loss caused by overheating.
Transmits power to the water pump (ensuring coolant circulation) and the hydraulic pump (driving working devices such as shovels), and the belt tension needs to be dynamically adjusted through the tensioning wheel.
Provide power for electrical systems (such as instrument panels, lighting) and air conditioning systems, requiring belts to have low noise characteristics (<= 65dB).
Drives the auxiliary hydraulic system.
