The development of the chassis of an unmanned tractor for a local complex of precision fanning is considered. The design is based on the kinematic scheme of the shaft gearbox, which implements a large number of modes and the principle of two-line transmission. A feature of this scheme is the presence of parallel load shafts. Keywords: wheeled tractor, autonomous control, two-line transmission, slipping, disc friction clutch. [email protected]

The heating in the running-in process of wet friction clutch is the key to research in this kind of products. In this paper, based on the shifting clutch composed of metal and paper-based friction liner, using MATLAB/SIMULINK software, the simulation model of friction clutch and the analysis model of conducting heat were established. Thus, the corresponding relationships were obtained, which were the total friction power and clutch temperature variation with the time during the running-in process. According to the simulation results, the main influencing factors on temperature control of wet friction clutch were analyzed during running-in process, and the results could provide reference for reasonable temperature rise control for the clutch.

The Coefficient Of Friction

This paper is intended to demonstrate that designers of wet clutches for power transmission can obtain the optimum friction characteristics for specific applications by considering the interaction between friction materials and lubricants. A friction clutch plate rig is described and the friction results obtained are presented. It is shown that a wide variation of coefficients of friction and frictional characteristics in wet friction clutches can be obtained by changing the oils and friction materials. In particular the coefficient of friction is dependent upon (1) the oil, (2) the materials of the sliding surfaces, (3) sliding speed, and (4) temperature. It is also shown that the coefficient of friction is affected by ( a) refining treatment given to the oil, ( b) different base oils, and ( c) additives.

Friction Clutch

For the third variant of the adaptive friction clutch with a separate force closure, the boundaries of the change in the value of the feedback gain are determined, within which the clutch has the highest accuracy of operation, if its load characteristic is realized in the form of a curve monotonically increasing in the range of the friction coefficient values. A variant of separate power closure is developed, which provides for the introduction of an additional spring into the clutch design in the closure node of the thorn pairs of the main friction group.

Selection Of

It is established that in practice it is possible to use adaptive friction clutches of the second generation with a separate power circuit, having two different forms of load characteristics: in the form of a curve monotonically increasing in the range of values of the coefficient of friction; in the form of a curve having a maximum point within the specified interval, excluding its boundary values. It is shown that the choice of the type of adaptive friction clutch and its technical and operational characteristics are mainly influenced by the value of the nominal torque and the specified maximum mass of the drive. Three main requirements for adaptive friction clutches operating as part of the machine drive are formulated.
