There are many different names for the types of vehicle clutches according to different classification methods. Let's take a look at the composition and principle of these two clutches.

    Tooth clutches (clutches that use internal and external teeth to form a mating pair) are mainly composed of shafts, coupling sleeves, internal gears, external gears, rotary sleeves, small holes, pins, baffles, spiral grooves, and screw holes.

    A coupling sleeve is installed on the shaft, the left end of the coupling sleeve is set with internal gear, the middle part of the coupling sleeve is connected with the external gear, and the right end of the coupling sleeve is equipped with a rotary sleeve. A baffle is installed on the right end face of the coupling sleeve. The toothless part of the external gear has two symmetrical spiral grooves, and the rotary sleeve has two symmetrical screw holes, and the bolt passes through the spiral grooves of the external gear and is threadedly connected with the rotary sleeve. The connection mode between the coupling sleeve and the external gear is a spline connection or an internal and external gear connection.

    The jaw clutch (the clutch of the chiseled pair composed of minion-like parts) is composed of two half-clutches with teeth on the end faces.

    Its working principle is that one of the two-and-a-half clutches is fixedly connected to the driving shaft, and the other is connected to the driven shaft with a guide key (or spline), and the clutch is moved axially along the guide key through the operating mechanism. It is connected by the interlocking of the end faces of the two half-clutches.

    The jaw clutch has a simple structure and a small outer dimension, and the two shafts connected will not rotate relative to each other after engagement; it is easy to operate and can transmit a large torque, but there is an impact when combined.
