Tooth belt double-shaft guide rod groove cam combination space mechanism for sliding-plug door

Abstract

The invention discloses a tooth belt double-shaft guide rod groove cam combination space mechanism for a sliding-plug door, relates to a sliding and plug, sealing, opening and closing mechanism for the sliding-plug door for a vehicle, in particular to the tooth belt double-shaft guide rod groove cam combination space mechanism for high-speed rail or other railway vehicles. The mechanism comprises a door frame, a motor, a driving wheel, a tooth belt, an auxiliary bearing shaft, a belt clamp, a tension device, a bearing pedestal, a driven wheel, an auxiliary shaft sleeve, a coupling rod A, a main shaft sleeve, a main bearing shaft, a coupling shaft B, a coupling shaft C, a guide rod sleeve, a roller, a roller shaft, a door carrying guide rod, a groove cam and a door leaf; a tooth belt transmission mechanism consists of the driving wheel, the tooth belt, a lower belt clamp, the tension device, the bearing pedestal, and the driven wheel; a double-shaft guide rod mechanism consists of the coupling rod A, the main shaft sleeve, the coupling rod B, the coupling rod C and the guide rod sleeve which are connected fixedly and integrally, the main bearing shaft, the auxiliary shaft, and the door frame; and a groove cam mechanism consists of the main shaft sleeve, the main shaft, the coupling rod C, the roller, the roller shaft, the door carrying guide rod, the groove cam, the door leaf, the main shaft sleeve and the door frame.

Description

technical field [0001] The present invention relates to a slotted cam combination space mechanism of a plug door with biaxial guide rod and relates to a plug sealing opening and closing mechanism of a vehicle plug door, in particular to a high-speed rail or other rail vehicle plug door with biaxial Guide rod slot cam combined space mechanism. Background technique [0002] At present, the automatic doors of rail vehicles at home and abroad mainly include three series of door systems: plug doors, external doors and built-in doors. The transmission methods mainly include screw transmission and toothed belt (ie synchronous toothed belt) transmission. [0003] The sliding door system is usually a single or double door leaf. When it is a double leaf, on the one hand, it needs to realize the opening and closing movement of the two door leaves that are opened and closed. The door leaf plug moves inward to ensure a good sealing effect after closing the door. Screw drive means that ...

AI Technical Summary

Problems solved by technology

[0011] In recent years, toothed belt transmission has been greatly improved in terms of material and structure. For example, neoprene toothed belt adopts glass fiber tensile layer, neoprene toothed belt, belt back and nylon cloth layer, polyurethane polyester tensile toothed belt etc. Combining the advantages of gear, chain and belt transmission, it overcomes the shortcomings of traditional toothed belt transmission, such as extension, fragility, and low load-bearing capacity, and has the advantages of accurate transmission, low noise, high load-bearing capacity, long life, high reliability, and energy saving. High efficiency, small pre-tightening force, etc.
