SU10922A1 - Gear for driving axle of self-propelled crews - Google Patents

Description

The present invention relates to a transmission mechanism for a driving axle of self-propelled crews, the essence of which is the use of two bevel gears, one of which is rotated directly from the drive shaft, and the other through friction discs loaded with levers that come into play under the influence of centrifugal force.

The drawing shows a horizontal section of the transmission mechanism, the device and action of which is as follows: the rotation of the drive shaft 1 is transmitted to box 3, and from the last bevel gear 4, 5, gear 4 of which is integral with said box, and gear 5 coupled with axle 6 and transmits movement to it using a conventional free-wheeling hub mechanism, whereby the other half is driven

during rotation by device 14. On one axle with wheel 5, wheel 7 sits on a key and meshes with wheel 8, the shaft of which ends with a friction disk 9, which can rotate freely in box 3. Lastly, it is also equipped with a second friction disk 12, which has no relative its rotational movement, but able to move along special guides. The disk 12 is supported by the ends of the levers 10, 10, loaded with the weights 15, 15 and sitting in the box 3 on a common axis. At a certain angular speed of the propeller shaft 1, when the centrifugal force is insufficient to overcome the spring 11, which tightens the levers 10, 10, the rotation of the semi-axles 6, 6 is communicated through the transmission 4.5. At that, gear 7.8 runs idle, rotating disk 9 in box 3. With some increase in the angular velocity of shaft 1, the centrifugal force begins to spread the levers 10, iO to the side, stretching the spring 11, as a result of which disk 12 is subjected to pressure of the delineated ends of the levers 10, 10, will be pressed against the disk 9. With a sufficient angular velocity of the shaft 1, and therefore with a sufficient amount of centrifugal force, the rotation of the semi-axes 6, 6 will be carried out already by means of the transmission 7, B, and the application for coupling wheels 5 with n Ouosyu 6 conventional mechanism of the hub with a free wheel will allow you to have the necessary in this case the difference in the number of revolutions of the semi-axis b and wheel sitting on it 5.

The subject of the patent.

The transmission mechanism for the driving axle of self-moving crews, characterized by the use of two bevel gear gears 4, 5 and 7, 8, of which the first is rotated directly from the drive shaft 1 and the box 3, and the second through friction disks 9,12, loaded with levers 10, 10 with weights 15,15, which come into play under the influence of centrifugal force, and the usual mechanism of the hub with a free wheel is used for coupling the wheel 5 to the semi-axle 6.
