BACKGROUND OF THE INVENTION The present invention relates to a multi-stage automatic transmission with a centrifugal shift coupling mechanism provided by a force-coupled force mechanism suitable for gearbox motors.

Multistage automatic transmissions with centrifugal radiation couplings provided with a force-poor coupling mechanism have a gear shifting gear shifted in dependence on the vehicle speed by the centrifugal force of the centrifugal shift clutch weights, and the driving force exiting the transmission by the force-force coupling mechanism of the centrifugal weight proportional to the driving force outgoing transfer. Thereby, the given exponential dependence of the vehicle speed at the beginning of the shift on the driving force exiting the gearbox satisfies the use of the motor drive force over the entire engine retraction range with respect to the torque variations of the motor and the engine loads. Advantageously, using the engine driving force throughout the engine retraction range, it allows the exponential variation of the initial shift to speed and the driving forces of the engine to be diverted from the selected speed by the vehicle's deflection weights, which, after overrunning the return force of the springs, move the baffle weight against the centrifugal force of the shift clutch weights. However, in addition to the substantial mass of pivotable weights, the disadvantage is that it is not possible to utilize the advantages of the various return arms of the output carrier arms to the centrifugal weight of the shift clutch at a lower gear ratio compared to the reduced effect assigned to the higher gear / smaller weight of the centrifugal weights and by eliminating the possibility of cyclic shifting (since at vehicle speeds in which the baffle weights are operating, there would be an unacceptable time-shifting of the shifting shift from time to time).

These disadvantages are eliminated by the multistage automatic transmission according to the invention, in that the baffle weights are coupled by springs with pivoted centering weights suspended on the drum of the clutch, wherein the baffle weights are spatially limited by the support surface and the stop surface of the pivot. centrifugal weights. Advantages of the multistage automatic transfer according to the invention consist in lowering the swiveling centrifugal weights as well as the deflecting weights as the mass of the swiveling weights and the baffle weights is used to control the shifting at low vehicle speeds. From the speed of the vehicle, in which the use of engine characteristics at higher engine loads requires a deflection of the force dependence on the vehicle speed at the start of the shift, a further increase in the spinning force of the baffle weights on the control clutch does not occur, and the entire centrifugal force of the spinning weights is produced. The contact of the output carrier and the swinging centrifugal weights can be solved by

In 196086, in the reverse gear, the return carrier of the output carrier decreases to a swiveling centrifugal weight, as the output blower arms control the effect of both the swivel centering weights and the baffle weights of all operating modes. It further reduces the mass of the swinging centrifugal weights and eliminates the possibility of cyclic shifting. The arms of the output carrier are a simpler, smaller and non-weakening, engaging drum of the shift clutch by recesses into which the arms engage. An exemplary embodiment of the present invention is shown in the accompanying drawings, in which: Figure 1 is a partial longitudinal sectional view of a two-stage flame transmission with a multi-plate clutch according to Figure 1; 2 shows a cross-section through a multi-stage automatic transmission according to the invention, with a view to a possible arrangement of the swiveling centrifugal weights, the baffle weights and the arm drive. The driving force from the engine recedes into the gearbox by the input wheel 1 3. The output wheel 12 of the gearbox 12 is rigidly connected to the drum 11 of the shift clutch 2. The shifting clutch 2, at a higher gear stage, interconnects the drum 11 with the reaction member 14 by centrifugal swiveling centrifugal weights 7 together with the effects of the baffle weights. In the lower gear, the reaction member 14 is opposed to the rotation in the reverse direction by the freewheel 3 of the housing body 15. The driving force exiting the gearbox is transmitted from the pins 16 of the drum 11 via the spinning weights 5 to the output driver 5 at both higher and higher gears. By switching the pivoted centering weights 6 to the arms 6, the force-absorbing mechanism is formed so that the proportion of the driving force from the gearbox is raised by the arms 6 on the pivoted ET Multi-stage automatic transmission with the centrifugal shift clutch provided with the mechanic &amp; and couplings having a baffle provided with baffle weights mounted on the pins of the drum, characterized in that the baffle weights (7) coupled to the swiveling centrifugal weights are raised by the springs. The arms 6 extend into the recesses 20 of the drum 11. The baffles 7 are suspended on the rollers 17 of the drum 11. At lower speeds, irrespective of the position of the pivoting centroids, the deflection weights T by the spring 6 pressed by the deflector weights 19 on the stop plate 18 of the swiveling centrifugal weights 6. The surface area of the baffle weights 7 is out of engagement with the pivotable centering support surface 10 and the centrifugal centrifugal weights of the centrifugal weights are used for changing. At the speed of the vehicle at which the desired velocity deflection deviation takes place as a function of the driving forces, the centrifugal force of the deflecting weights 7 overcomes the spring force a and the deflection weight deflects in terms of centering force until the contact surface While increasing the speed of the vehicle, a further increase in the centrifugal force of the baffles 7 is captured by the support surface 10 of the pivotable centrifugal weights 7, whereby the predetermined force of the springs continues to act unchanged in the sense of centrifugal force. the swinging-centering weights £. According to the mutual arrangement of the pins 16, the pins 17, the contact surface 6 and the support surface 10, the increase in the centrifugal force of the deflecting weights 7 by the support surface 10 on the pivotable weight can be influenced by the force of the anti-skid force / example in FIG. in the sense of the centrifugal force of the swiveling centrifugal weights 7, or the centrifugal force of the spinning weights 7, does not need to affect the centrifugal weights. 4 »OUT. the weights (4) suspended on the pins (16) of the drum (11) of the shift coupling (2), the deflection weights (7) being limited by the support surface (10) and the stop surface (18) of the swinging centrifugal weights (14). 2 sheets of drawings by Severoprafí ·. n. p .. race 7.
