Current-changed automatic clutch for automobile

Abstract

The invention discloses a current-changed automatic clutch for an automobile, comprising a right end cover, a left end cover, a central shaft, driving pieces, driven pieces, a left insulating cover, a right insulating cover, a sleeve and current change liquid, wherein the sleeve sheathed on the driving piece and a No.1 spacer bush is arranged between the right end cover and the left end cover; the No.1 spacer bush is arranged between the adjacent driving pieces; a No.1 insulating piece is arranged on a through hole of the spacer bush of the driving piece; the right end cover, the driving pieces arranged at intervals, the No.1 spacer bush and the left end cover are fixedly connected with one other by bolts; the central shaft and the driven pieces are connected by a spline pair; a No.2 spacer bush is arranged between the adjacent driven pieces; a No.2 insulating piece is arranged at the periphery of the driven piece; and the driving pieces and the driven pieces are arranged at intervals. The central shaft is arranged on the left end cover and the right end cover by the left insulating cover, the right insulating cover, a No.2 bearing and a No.1 bearing, the current change fluid is filled in a cavity formed between the adjacent driving pieces and driven pieces, a sleeve with small diameter of the central shaft is sheathed with a conducting ring, and a connecting plate is fixedly installed on the left end cover.

Description

technical field [0001] The invention relates to a clutch belonging to the technical field of automobile transmission, more specifically, the invention relates to an electrorheological automatic clutch for automobiles. Background technique [0002] Clutch is the part that connects the engine and gearbox in the car transmission system. Most of the clutches used in cars are friction clutches, which use the engagement and separation between the driving disc and the driven disc to transmit and interrupt power. This kind of clutch has some disadvantages. For example, the pretightening force of the pressure plate gradually decreases with the wear of the friction plate during long-term use, so that the torque that the clutch can transmit gradually decreases, and finally makes it slip and fail; During the shifting process, the separation and engagement process of the friction clutch takes a long time and is not smooth, which will cause shocks at starting and shifting, and affect driv...
