[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 It combines the advantages of gears, chains and belt drives, overcomes the shortcomings of traditional toothed belt drives such as extension, fragility, and low load-bearing capacity, and has accurate transmission, low noise, high load-bearing capacity, long life, and high reliability. Energy-saving, high-efficiency, small pre-tightening force, etc.

Abstract
The invention relates to a tooth strap, double-shaft rocking rod and guide rod, and groove-shaped cam combined spatial mechanism of a sliding plug door, which relates to an open and close mechanism of sliding plug hermetization of a railway vehicle automatic door, in particular to the tooth strap, double-shaft rocking rod and guide rod, and groove-shaped cam combined spatial mechanism of the sliding plug door of a high-speed railway vehicle and other railway vehicles. The tooth strap, double-shaft rocking rod and guide rod, and groove-shaped cam combined spatial mechanism comprises a door frame, a motor, a driving wheel, a tooth strap, an auxiliary shaft, a lower strap clamp, a tensioning device, a bearing seat, a driven wheel, an auxiliary shaft sleeve, a rocking guide rod, a load-bearing shaft, a guide rod, a load-bearing shaft sleeve, a rocking rod, a doorknob, a roller, a roller shaft, a groove-shaped cam and a door leaf; a tooth strap transmission mechanism comprises the driving wheel, the tooth strap, the lower strap clamp, the tensioning device, the bearing seat and the driven wheel, and a double-shaft rocking rod and guide rod mechanism comprises the auxiliary shaft, the auxiliary shaft sleeve, the rocking guide rod, the load-bearing shaft, the guide rod, the load-bearing shaft sleeve and the rocking rod; and a groove-shaped cam mechanism comprises the load-bearing shaft, the load-bearing shaft sleeve, the rocking rod, the doorknob, the roller, the roller shaft, the groove-shaped cam, the door leaf and the door frame. The mechanisms are combined into the tooth strap, double-shaft rocking rod and guide rod, and groove-shaped cam combined spatial mechanism.
Description
technical field [0001] The present invention relates to a plug-in door tooth belt dual-axis rocker guide bar groove-type cam combination space mechanism, which relates to a plug-in sealing opening and closing mechanism for an automatic door of a rail vehicle, in particular to a plug-in door for a high-speed rail or other rail vehicles. Toothed belt dual-axis rocker guide bar 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 ...
