[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0019] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, terms such as "installation", "provided with", "sheathed / connected", "connection", etc. shall be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0020] Embodiment 1: Refer to Figures 1-3 A pneumatically controlled two-speed clutch shown in the figure, which includes a clutch housing 1 and a sun gear shaft 5. The sun gear shaft 5 extends into the clutch housing 1. An A chamber 11 is provided in the clutch housing 1, a B chamber 12 is provided in the clutch housing 1, and a transmission assembly is provided in the clutch housing 1 to facilitate the transmission between the air cylinder 2 and the clutch cylinder body 8. The transmission assembly includes an air cylinder 2 provided in the clutch housing 1, and a clutch cylinder body 8 is provided in the clutch housing 1; a piston rod 10 is provided in the clutch housing 1, and the A chamber 11 is arranged between the air cylinder 2 and the clutch cylinder body 8; a steel gear 6 is provided in the clutch housing 1, and the inner wall side of the clutch housing 1 is fixedly connected with a spring 7. The two ends of the spring 7 are respectively fixedly connected with the side of the clutch housing 1 and the steel gear 6 to facilitate the movement of the steel gear 6 and the air cylinder 2. A transmission flange 4 meshing with the sun gear shaft 5 is provided in the clutch housing 1, and a pneumatic joint 9 is provided in the clutch housing 1; a reducer gear ring 3 meshing with the steel gear 6 is provided in the clutch housing 1.

[0021] In this embodiment, the clutch has a total of 3 clutch states.
