Description

Technical Field

[0001] The utility model relates to the technical field of forklift gearboxes, and more specifically, to a mounting structure of a forklift gearbox. Background Art

[0002] Forklifts are industrial handling vehicles, which refer to various wheeled handling vehicles for loading and unloading, stacking and short-distance transportation of palletized goods. Since the engine cannot be reversed, the forward and reverse movement of the forklift needs to be solved by the transmission. The main function of the transmission is to adapt to the vehicle's starting, accelerating climbing and high-speed driving on flat roads under various road conditions. The transmission transforms the torque and speed output by the engine to adapt to the driving requirements. The forklift also needs to be installed with a transmission to ensure the movement of the forklift. The correct transmission installation method is essential for the normal operation of the forklift and improves work efficiency. First, adjust the new transmission and correctly adjust the new transmission according to the specifications and requirements of the forklift; then support the transmission and use a jack or other suitable support device to place the new transmission in the installation position of the vehicle; then connect the fixing bolts, according to the specifications and requirements provided by the manufacturer, connect the fixing bolts one by one to fix the transmission on the vehicle, and use a torque wrench to ensure that the tightening force of each bolt meets the specified standard to avoid over-tightening or over-loosening, and connect other components at the same time; finally, check the installation quality. After the installation is completed, conduct a comprehensive inspection to ensure that all parts are correctly connected and there is no looseness or misalignment.

[0003] However, the position of the support frame for placing and installing the gearbox on the forklift frame is fixed, which is not convenient for ensuring that the transmission, engine and drive axle are connected exactly, and there is a tendency for installation errors; and after installation with bolts and nuts, the bolts and nuts are directly exposed to the outside, which are easily affected by the external environment and cause rust and looseness, making it inconvenient for subsequent disassembly and maintenance of the gearbox. For this reason, we propose a mounting structure for a forklift gearbox. Utility Model Content
