Background technology
At present, the hydraulic-driven back axle of two kinds of repackings has appearred in tractor rear axle structure design aspect: a kind of is with the repacking of three-wheel vehicle drive axle, use the HM Hydraulic Motor unidirectional drive, but reversing is still by gear transmission, therefore, need two covering devices, close the switch control oil channel, shift gears with a sets of transmission mechanism again with a liquid; Another kind of " but hydraulic actuator of a kind of bi-directional drive tractor rear axle " utility model patent that waits three people to apply for by me is reequiped with automobile axle, and with support HM Hydraulic Motor is connected with retarder angle tooth bead.The former has set up the device of a cover hydraulic driven trailer wheel on the basis of common frame-steered tractor, strengthened hill climbing ability, but must handle back axle with two covering devices, makes structure and complicated operationization.The latter further improves on the former basis, has increased change-over valve, can forward and backward bi-directional drive, but the support connection mode causes structure to be disperseed, and deadweight increases, and cost raises, and needs to continue to improve and perfect.
Summary of the invention
The utility model is intended to further improve on the basis of " but hydraulic actuator of a kind of bi-directional drive tractor rear axle ", adopt integral type on the structure, make HM Hydraulic Motor and back axle integrated, structure is more excellent, good looking appearance, cost descends, and controls back axle with a joystick and advance or retreat simplified control.
For this reason, the utility model adopts following technical scheme:
Comprise headstock, gear type pump, fuel tank, change-over valve, HM Hydraulic Motor, HM Hydraulic Motor clutch assembly, change-over valve handle in its structure.Gear type pump is installed on the headstock, the two ends of gear type pump oil inlet be tightly connected respectively gear type pump and fuel tank, the two ends of gear type pump oil outlet pipe be tightly connected respectively gear type pump and change-over valve, the two ends of oil return pipe be tightly connected respectively fuel tank and change-over valve, be tightly connected with two oil pipes are parallel between change-over valve and HM Hydraulic Motor, the change-over valve handle is installed on the change-over valve.In addition, also comprise back axle assembly in this structure, HM Hydraulic Motor is installed on the housing of back axle assembly, and the rotating shaft of HM Hydraulic Motor links by HM Hydraulic Motor clutch assembly and back axle assembly driving gear shaft.
Simultaneously, in the structure of back axle assembly housing, driving gear, driving gear shaft, driven gear, differential assembly are arranged.Driving gear, driving gear shaft, driven gear, differential assembly are installed in the housing, and driving gear and driving gear shaft link with key, driven gear and differential assembly housing bolt together.
The utility model has outstanding characteristics: the one, HM Hydraulic Motor, driving gear and axle, driven gear and differential assembly are installed in the rear axle housing body, make HM Hydraulic Motor and back axle integrated, strengthened the globality of structure, be convenient to install, be convenient to keep a public place clean, can improve performance, reduce deadweight, cost-cutting.The 2nd, with the change-over valve handle just the may command back axle advance or retreat, make it the operation simpler.
