The invention discloses a high-clearance self- propelled chassis, comprising a frame, a front travelling wheel, a rear travelling wheel, a drive device, a left final transmission device and a right final transmission device, wherein, the drive device comprises an engine, a gear-box, a main reducing gear; the gear-box is connected with the engine; the main reducing gear is connected with the gear-box through a transmission shaft, and is hinged with the frame through a rear suspension mechanism; the left final transmission device and the right final transmission device are arranged on the frame, are respectively connected with the main reducing gear, a left rear travelling wheel and a right rear travelling wheel, and respectively comprise a primary transmission mechanism driven by a chain, and a secondary transmission mechanism driven by a chain or a gear. The final transmission structure of the invention adopts the matching of a primary chain transmission and a primary gear reducing mechanism, or adopts a transmission mode of the matching of the two-stage chains, which not only avoids drawbacks caused by the condition that multilevel gear transmission needs to be added when the final transmission fully adopts a mode of gear transmission matching for realizing high clearance, simplifies the transmission structure, but also effectively improves ground clearance of a machine, thus realizing high clearance.
Description
technical field [0001] The invention relates to a high ground clearance self-propelled chassis, in particular to a high ground clearance self-propelled chassis whose final drive adopts chain drive. Background technique [0002] The final drive of a machine is the drive after the differential or steering and before the drive wheels to further increase the gear ratio. Usually the transmission ratio of the final drive is relatively large, so as to reduce the stress on the transmission components such as the gearbox and the central transmission, and reduce their structural size. There are two types of final drive: external meshing cylindrical gear drive and planetary gear drive. At present, the final transmission structure of agricultural machinery chassis mostly adopts gear transmission, and the ground clearance of the machine is relatively low. In order to achieve high ground clearance and increase the ground clearance of the machine chassis, if gear transmission is still use...
