FIELD: mechanical engineering; transport facilities wheels. SUBSTANCE: transport facility wheel has drum including rim part, disk part and hub. Multi-disk brake located in drum has drive in form of cylinder unit with pistons and friction disk stack located in cooling chamber which is communicated with atmosphere; it is formed by brake body and two circular partitions. One partition is located between rim part and friction disk stack and other partition is formed by cylinder block and friction disk stack. Formed additionally in wheel is circular receiver whose outer wall is organized by rim part and hub and inner wall is organized by circular partition located before rim part and brake body. Receiver inlet is communicated with air supercharger and its outlet is communicated through supply holes found in circular partition and in brake body with cooling chamber and cavity organized between cylinder block and circular partition. EFFECT: enhanced reliability; increased service life. 1 dwg |
