Abstract
The article presents an analysis of the results of the experimental study, during which the load was determined for the gear wheel shaft of the rear-axle gearbox of the all-terrain vehicle transmission on ultra-low pressure tires TREKOL-39041. These all-terrain vehicles have very good cross-country ability and are indispensable for off-road operation during mudslide or deep snow, but they often have transmission failures, especially the shafts on which the wheel reduction gear of both the front and rear axles are installed. In the transmission of these vehicles on the tires of ultra-low pressure, the units from a number of commercially produced vehicles were used. The use of such units reduces the cost of construction and simplifies the production technology, maintenance and repair, but also creates certain difficulties in the design of this type of ATV, in some cases, increases the weight and dimensions. The experimental data are compared with the data of other authors and with calculated data. The obtained data are compared with the experimental and calculated data on the loading of the transmission elements of the UAZ-31512 automobile, the main units of which are used in the layout diagram of the snow aerial vehicle. The results of the studies indicate that the main reason for the failure in the transmission of the snow thrower TREKOL-39041 is the operating conditions, including somewhat different from ordinary tires, the interaction of the ultra-low pressure tires with the best traction and coupling properties with the supporting surface, and a more complex transmission scheme, than for conventional all-terrain vehicles, in which the transmission is simply assembled from the units of a number of serially produced automobiles and calculations of the dynamic loading of its elements on the forced modes are not conducted, which leads to the appearance of significantly exceeding the permissible values of stresses in the splined joint of the wheel gear shaft, to its plastic deformation and failure.
