ABSTRACT:
A rotatable drive spindle for quick mounting comprises a hollow shaft (10) mounted rotatably in two bearings (3a, 3b) and a control rod (9) passing through the hollow shaft (10) and displaceable between a locking position and an unlocking position. A prestressed resilient spring is provided continuously to urge the control rod (9) toward the first locking position and a pneumatic jack (6) is provided to act against the spring (19) and press the control rod (9) toward the unlocking position. This jack (6) is mounted relative to the hollow drive shaft (10) and to the control rod (9) with an arrangement analogous to that of a hub puller, which is to say in a manner such that pulling on a configuration (11) secured to the hollow drive shaft (10) presses on the control rod (9) but does not exert any force on the bearings (3a, 3b).
