载重车钟形制动鼓

Load-carrying truck bell-shaped type brake drum

Abstract

本实用新型是涉及到一种载重型车制动系统,具体地说是载重车制动器的制动鼓,即载重车钟形制动鼓。把轮毂和制动鼓合二为一,一次铸造成型,经加工后,安有轴承和预留有安螺栓的孔,螺栓孔有4个,并均匀分布在螺栓台面上。同轴度和装配精度比原来大有提高,减少了轮毂部件简化了生产工艺,相应地降低了生产成本,以及减轻了重量,确保了产品受力均匀分布和传递,提高了产品的质量。
The utility model relates to a brake system of a heavy vehicle. In detail, the system is a brake drum of the heavy vehicle, a clock-shaped brake drum. A hub and a brake drum are integrated together and cast & shaped in one time. After the processing, the brake drum is provided with a bearing and 4 bolt holes evenly distributed on the bolt table. The coaxial degree and the assembly precision are greatly promoted. Hub parts are reduced, the manufacture process is simplified and thus the production cost is reduced. Moreover, the weight is reduced too. The bolts are evenly distributed to ensure the force on the product is evenly distributed and transferred and the product quality is promoted.
