Large-tonnage wheel excavator transmission structure
The invention discloses a large-tonnage wheel excavator transmission structure. The transmission structure comprises a hydraulic oil tank, a multi-way valve, a power device, a transmission device, a gearbox and an upper tank, wherein the power device, the transmission device, the gearbox and the upper tank are sequentially connected; and the transmission structure further comprises a working pump set and a transmission connecting shaft, the working pump set comprises two hydraulic pumps, the hydraulic pumps are correspondingly connected with power output ends of the transmission device, an oil inlet of each hydraulic pump is provided with an oil inlet pipeline connected with the hydraulic oil tank, an oil outlet of each hydraulic pump is provided with an oil outlet pipeline connected with an oil inlet of the multi-way valve, an oil outlet of the multi-way valve is provided with an oil return pipeline connected with the hydraulic oil tank, and the gearbox is in transmission connection with the upper tank or the transmission device through the transmission connecting shaft. Compared with the prior art, the requirement for large displacement can be met, and the transmission cost is reduced; and the structure is optimized, cab layout is facilitated, and meanwhile operation stability is improved.
本发明公开一种大吨位轮式挖掘机传动结构，包括液压油箱，多路阀，以及依次连接的动力装置，传动装置,变速箱以及上箱，其中，还包括工作泵组和传动连接轴，工作泵组包括两个液压泵，液压泵与传动装置的动力输出端对应连接，液压泵的进油口具有与液压油箱连接进油管路，液压泵的出油口具有与多路阀的进油口连接的出油管路，多路阀的出油口具有与液压油箱连接的回油管路，变速箱通过传动连接轴与上箱或传动装置传动连接。与现有技术相比，本发明能够实现大排量需求，降低传动成本；并且优化结构，方便驾驶室布局，同时提高作业的稳定性。
