Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings.

[0015] As shown in the figure, the inner rotor (1) and the outer rotor (2) are connected and supported by the right end cover (3), the left end cover (4) and the bearing (5), both of which can freely rotate axially. The inner rotor (1) is connected to the output shaft of the engine, and the outer rotor (2) is connected to the input shaft of the main reducer. The inner rotor (1) and the outer rotor (2) are processed from solid steel, which can withstand relatively large torque. In this example, 12 A-phase field windings (7) and B-phase field windings (8) are evenly distributed on the inner rotor (1). , L7, L9, L11), and the B-phase excitation winding (8) is composed of windings (L2, L4, L6, L8, L10, L12). The collector ring is 4 wires. Connect the excitation winding to the output terminals of the A-phase full bridge (Q1, Q2, Q3, Q4) and B-phase full bridge (Q5, Q6, Q7...

Abstract

The invention discloses an automatic transmission of an automobile. The automatic transmission comprises an outer rotor, an inner rotor, a left end cover, a right end cover, bearings and collecting rings, wherein the inner rotor is connected with an output shaft of an engine, and the outer rotor is connected with an input shaft of a main speed reducer. The automatic transmission is characterized in that the outer rotor is made of solid steel and can bear larger torque; the inner rotor is also made of solid steel; two-phase excitation windings are uniformly distributed on the inner rotor, and every two two-phase excitation windings are interphase; the collecting rings are of four-wire type and are respectively connected to two full-bridge outputs of a controller; and direct current can be fed into the collecting rings, thus forming a constant magnetic field on the rotor, and two-phase alternating current with a phase difference of + / - 90 degrees can be also fed into the collecting rings, thus forming a positive rotation magnetic field and a reverse rotation magnetic field. The problems of high manufacturing cost and small speed range of an existing automatic transmission of the automobile are solved; and the automatic transmission is suitable for various automobiles taking gasoline and diesel engines as power.

Description

technical field [0001] The invention relates to the field of automobile industry, and is an automatic transmission suitable for various automobiles powered by gasoline and diesel engines. Background technique [0002] At present, automotive automatic transmissions use mechanical connection to transmit power. The disadvantages are that the structure is relatively complex, the manufacturing cost is high, and whether it is gear or pulley transmission, the ratio range is relatively narrow due to the mechanical size of the transmission wheel. . Contents of the invention [0003] In order to solve the problems of high manufacturing cost and small shifting range of the automatic transmission for automobiles, the invention provides a simple double-rotor structure and an automatic transmission for automobiles which relies on electromagnetic coupling to transmit power. [0004] The technical solution of the present invention is an automatic transmission for automobiles with a dual-...
