本发明公开一种带有链条压紧机构的双向行走动力总成,包括双向输出齿轮箱和链条压紧机构,双向输出齿轮箱包括动力源、动力输出轴、拼装式齿轮箱、子巷道主动链轮、主动螺旋伞齿轮、变向螺旋伞齿轮和主巷道主动链轮。链条压紧机构,包括与链条配合的压紧链轮、转动臂、转动臂支架和推拉摆臂。优点,本发明的双向输出齿轮箱,整体体积紧凑,满足四向车,车体内空间小的安装要求。本发明的链条压紧机构,整体结构紧凑,结构简单可靠性高,主巷道行车轮动力输入轴在提升机构的驱动下上升或下降的同时,转动臂绕中部铰接点摆动,使得转动臂的左端和右端交替上升或下降;当主巷道行车轮动力输入轴上升时,转动臂右端下降将链条下压,绷紧链条。
The invention discloses a bidirectional walking power assembly with a chain pressing mechanism. The assembly comprises a bidirectional output gear box and the chain pressing mechanism, and the bidirectional output gear box comprises a power source, a power output shaft, a split mounting type gear box, a sub-roadway driving chain wheel, a driving spiral bevel gear, a turning spiral bevel gear and amain roadway driving chain wheel. The chain pressing mechanism comprises a pressing chain wheel matched with a chain, a rotating arm, a rotating arm support and a push-pull swing arm. The bidirectional output gear box has the advantages of being compact in overall size and capable of meeting the installation requirements of a four-way vehicle and small space in a vehicle body. The chain pressingmechanism is compact in overall structure, simple in structure and high in reliability; the rotating arm swings around a middle hinge point while the main roadway traveling wheel power input shaft isdriven by a lifting mechanism to ascend or descend, so that the left end and the right end of the rotating arm alternately ascend or descend; and when the main roadway travelling wheel power input shaft ascends, the right end of the rotating arm descends to press down the chain, and the chain is tightened.
