Description

Technical Field

[0002] The gearbox of a road roller is usually an important part of the transmission system of a road roller. The gearbox of a road roller is a power transmission device that connects the engine and the tires or tracks of the road roller. By changing the transmission ratio and torque, the speed adjustment and power output of the road roller under different working conditions are achieved. When the gearbox of a road roller is working, heat dissipation operation is required. The gearbox radiator of the road roller is a key component in the gearbox system of the road roller, which can protect the gearbox from damage caused by overheating. The gearbox of a road roller usually uses the flow of gearbox oil or other media to take away the heat, and then flows into the inside of the gearbox radiator of the road roller for heat dissipation operation.

[0003] The existing roller gearbox cooling mechanism usually includes a radiator and a pipeline. The radiator usually uses a pipeline to allow gearbox oil or other media to flow, and the gearbox oil enters the interior of the radiator, and then the radiator is used to perform heat dissipation operations.

[0004] The radiator is usually installed at a designated position on the roller. A mounting side plate is provided on the radiator, and then the mounting side plate is mounted to the roller using multiple bolts. However, when the roller is compacting the road surface, some soil may splash, and then the soil may splash onto the ends of the bolts. If it rains, the soil may stick to the surface after the rain, which increases the cleaning steps of the bolts and affects the subsequent disassembly efficiency of the radiator. As a result, it is inconvenient to shield and protect the mounting side plate bolts after the radiator is installed, and there are certain limitations. Utility Model Content
