Шарнир Doohap Lacetti DRKD-05

It is used in the drive systems of steerable wheels of passenger cars with independent suspension and, less often, rear wheels and in the drives of the front wheels of SUVs, sometimes on rail rolling stock. The first attempts to implement front-wheel drive were carried out using conventional gimbal joints. However, if the wheel moves in a vertical plane and at the same time is pivoting, the outer hinge of the semi-axle has to work in extremely difficult conditions with angles of 30—35°. And already at angles greater than 10—12°, power losses increase sharply in the driveshaft, besides, rotation is transmitted unevenly, the wear of the hinge increases, tires wear out quickly, and gears and transmission shafts begin to work with large overloads. Therefore, a special joint was required - a joint of equal angular velocities, devoid of such disadvantages, transmitting rotation evenly regardless of the angle between the connected shafts. There are several types of hinges of equal angular velocities that differ from each other not only in design, but also in their places of use.
