摘要

the invention relates to the means of testing power train components of heavy vehicles, namely, adjustment and testing gearboxes, mainly u0433u0438u0434u0440u043eu043c u0435u0445u0430u043du0438u0447u0435u0441u043au0438u0445 (u0433u043cu043au043f)no load and under load, and solves the problem to increase the accuracy of installation of these devices.support struts (5) to install the gearbox (6) placed on the support frame (1) on a movable transverse rails (4).implemented in the form of shell (26) with u043au0440u043eu043du0448u0442u0435u0439u043du043eu043c (27) in the spiral guide (28) and perceived stress in hard bearing with flow spherical u043fu043eu0434u043au043bu0430u0434u043du044bu043c if u0446u043eu043c (30).by transmitting only u043eu0441u0435u0432u0443u044e component load on the supporting bar (5), which eliminates the parasitic moments of force.the drive motor (9) with an input shaft u0433u043cu043au043f (13) controlled by an optical control device of a protective housing (10), to joint part.the measurement sensors installed in casing (25) and is connected through hoses to the technological holes of gearboxthat excludes the influence of hydrodynamic strikes the working fluid on the sensitive elements of the sensors.the parameters of u0433u043cu043au043f (6) with training can be measured when a load from the transmission motor (9) to the input shaft u0433u043cu043au043f.in the tests, the gearbox under load using integrated termination (brake) motor (32), it is set on a rail (35, 36,37) for spatial displacement and provide optical (laser) device controls the installation shaft u043du0430u0433u0440u0443u0437u043eu0447u043du043eu0433u043e motor (38).which determine the orientation of the axis of the output shaft of the motor (33) and the u043du0430u0433u0440u0443u0437u043eu0447u043du043eu0433u043e conjugation beam laser output shaft with a flange u0433u043cu043au043f stationed at u0437u0430u0449 u0438u0442u043du043eu043c screen (7).due to the transverse bar (4) with u043eu043fu043eu0440u043du044bu043cu0438 uprights (5) connecting shafts the kinematic connection and conduct safety and testing program.
