DESIGN OF CONTINUOUSLY VARIABLE TRANSMISSION OF TRACKED TRACTOR (DESIGN OF WET SHIFT CLUTCH)
ABSRACT
The design content and the design guiding ideology are introduced in this paper. This design content is the design wet shift clutch of tracked tractor stepless transmission gearbox. The hydro-mechanical continuously variable transmission (HMCVT) is a new type transmission device, which consists of a mechanical transmission (MT) combined in parallel with a hydrostatic transmission (HST) featuring a pair of hydraulic units. The HMCVT has a continuously variable shifting ratio by the combination of HST and MT and achieves high efficiency by MT. This device can greatly improve power and fuel economy characteristics and operation automation level of vehicle. The wet multi-disk shifting clutch is one of main parts of power-shift tractor’ gearing. This paper discusses systematically the structural design features of this clutch, including the design of key parts such as friction plate, return spring and quick draining oil valve, the implementation of cooling and lubrication and the selection of sealing devices. The analysis and calculation of torque capacity, heat capacity and service life of this clutch are also carried out.
Key words: tractor, hydo-mechanical stepless transmission, load shift, wet multiple disc shift clutch
