Transmission box contains 1 transmission and installed by two supports transfer case 2, which are connected high-speed device transmitting torque, comprising a flexible coupling 4 with elastic centering element 6 made in the form of glass on the outer cylindrical surface of which has a longitudinal groove 7. Between the elastic clutch and transfer case installed hinge 9 equal angular velocity, and its center is located from the center of the elastic coupling at a distance not exceeding the outer diameter D of the hinge of equal angular speeds. 2 Il. The invention relates to transport machinery and can be used mainly in the transmission all-wheel drive passenger cars.Known transmission car VAZ-2121, containing the gearbox and mounted on the body by means of supports transfer box connected by a transmission device torque, carried out is Mira unequal angular velocity 
The disadvantage of this design is the increased level of noise and vibration arising in the transmission especially when a sudden change in rotational speed of the crankshaft of the engine. Moreover, when installed on the car the engine displacement of more than 1600 cm3vibration at a time of intense pick becomes invalid.The purpose of the invention, the reduction of noise and vibration arising in the transmission of the vehicle.This objective is achieved in that in the transmission of the vehicle containing the gearbox and mounted on the body by means of two supports transfer box connected by an elastic coupling with the centering element according to the invention, between the elastic clutch and gearbox installed the hinge of equal angular speeds, not having axial freedom, the center of which is located from the center of the elastic coupling at a distance not exceeding the diameter D, thus centering the elastic coupling element is made of elastic material and in the form of glass on the outer cylindrical surface of which is made of at least one longitudinal groove, where D is the outer diameter of the hinge.The joints of equal angular velocity is abnominal torque transmission. Also widely known application of elastic couplings with elastic centering devices, for example, long-wheelbase cardan shafts, in which they are used in particular for noise reduction 
Comparative tests with atomic turning on the hinge of equal angular speeds and elastic (rubber) of the centering element in the known construction of transmission of the car VAZ-2121 instead of cross hinge and steel centering element. Moreover, the CV joint was mounted so that its center was located from the center of the elastic coupling at a distance not exceeding the diameter of the hinge of equal angular speeds. And elastic centering element was made in the form of glass on the outer cylindrical surface of which is made of at least one longitudinal through groove. The test results showed that the parameter level of the internal noise of the claimed design transmission (with the hinge of equal angular speeds and elastic centering element) in comparison with the elementwise application of the data nodes in a known construction of transmission has the additional effect of 1.5 dB and 1.5 dB for the level of vibration accelerations.
In addition, the application of the proposed innovations of the claimed design transmission allows to increase the working angle in the hinge of equal angular speeds, which reduces the accuracy requirements relative position of the gearbox and the transfer case to the transmission Assembly.In Fig. 1 shows the inventive design of the transmission of the vehicle of Fig. 2 is a top view.The transmission of the vehicle consists of the following components. Box 1 transmission, transfer case 2 mounted by means of two bearings 3 on the vehicle body. Transmission and transfer case are connected between a high-speed transmission device torque, containing mounted on the output shaft 4 of the gearbox elastic jointing sleeve 5 with the centering element 6 is made of elastic material such as rubber. The centering element has the shape of a Cup, on the outer cylindrical surface of which is made of the longitudinal groove 7. Moreover, the number of grooves may be greater than one. Coaxial elastic coupling 5, the input shaft 8 of the transfer case 2 has a hinge 9 equal angular velocity, which is not able to move wdol clutch and the center O' of the CV joint does not exceed the outer diameter of the hinge of equal angular speeds.The torque is transmitted from the engine to the gearbox 1 and via the output shaft 4 of the latter on the flexible coupling 5, and then through the hinge 9 is equal to the angular velocities of the input shaft 8 of the transfer case. Due to the fact that between the elastic sleeve 5 and the output shaft 4 of the gearbox installed centering elastic element 6, is cut-off part of the vibration transmitted from the transmission 1 gear 2 and from it through bearings 3 on the vehicle.When the transmission of torque, this embodiment of the transmission reduces noise and vibration arising from the motor, and the linear displacement of the drive components and the angular movements of the housing of the transfer case around an axis passing through its support.
The TRANSMISSION of the VEHICLE containing the gearbox and mounted on the body by means of two supports transfer box connected by an elastic coupling with the centering element, characterized in that between the elastic clutch and gearbox installed the hinge of equal angular speeds, not having axial freedom, the center of which is located from the center of the elastic coupling at a distance not exceeding the outer diameter is fixed is the author of the cylindrical surface of which is made of at least one longitudinal groove.
