STAND FOR RESEARCH WORK twin wheels FREIGHT VEHICLES

摘要

Utility model stand for research work paired wheels of commercial vehicles relates to mechanical engineering and can be used to study the workflow in contact with the road tires paired wheels located at different vertical loads, with different types of tread patterns of tires and different internal air pressures in them, as well as on different types of road surfaces. Designed stand for a working process twin wheels of commercial vehicles differs from known prototypes in that one of the paired investigated wheel rigidly fixed to the axis and the other wheel is fixedly mounted on the hub, installed on the same axis. Inside the nave there are two ball bearings for free rotation of the test wheel relative to each other. If necessary, a rigid connection of the two wheels of the test, is provided on the hub axle lock using a removable locking pin. Due to the replaceable spacer shims of different length, mounted between dual wheels on an axle, provided distance change between wheels during experiments. To create vertical load corresponding to both paired wheels removable load attached to the vertical axis of the T-shaped through earring counterweight pulley. The utility model will optimize the selection of tires twin wheels, mounted on the rear hub of trucks, to minimize the circulating power between them, thereby significantly reducing tire wear paired wheels, improving fuel efficiency of cars, as well as expand the range of research.
