Detailed Description
As shown in fig. 1 to 6, a torsional damper for a hybrid transmission includes a damper body 1, a stopper pin 2, a disc spring 4, and two pressure plates 3; the outer friction plate 5 of the shock absorber body 1 is tightly pressed in the shell of the shock absorber body 1 through the two pressure plates 3 and the disc spring 4 to form a torque limiter, required friction force (namely the maximum torque borne by the system) is set, when the torque borne by the shock absorber is larger than the friction force, the disc spring 4 fails, and the friction plate 5 slips to protect the whole system.
The two pressure plates 3 are arranged on two sides of the friction plate 5, the disc spring 4 is arranged between the friction plate 5 and the shell of the shock absorber body 1, the friction disc 6 of the shock absorber body 1 is provided with a limiting hole, the limiting pin 2 is arranged in the limiting hole in a clearance mode, and the limiting pin 2 is connected with the hub sleeve 8 of the shock absorber body 1.
The position of a limiting pin 2 connected with a friction disc 6 is set, and a damping element pressed on the friction disc 6 does not participate in acting within the normal working range (the spring angle fluctuation range is within 3 degrees) of an engine; when the negative angle engine is started and the positive working torque has large fluctuation (larger than 3 degrees), the limiting pin 2 drives the friction disc 6 to move, and the friction disc enters a large damping mode to reduce impact.
As shown in fig. 5, when the forward spring angle changes within 3 °, only hub sleeve 8 operates; otherwise, the limiting pin 2 drives the friction disc to work, and the friction disc enters a large damping mode.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
