Abstract
A clamp device having a body made of a pair of half bodies connected and unified with a fixation member. One of friction plate units is elastically pushed by a first spring in a direction parting from a disc and in a rotating direction of the disc simultaneously, and the other of the friction plate units is elastically pushed by a second spring in a direction parting from the disc and in a reverse direction of the rotating direction simultaneously.
Claims4
A clamp device for a disc comprising
- a pair of friction plate units pressed to both sides of the disc by a pair of fluid pressure pistons enclosed in the body to stop rotation of the disc,
- a pair of half bodies connected and unified with a fixation member,
- a first spring which elastically pushes one of the friction plate units in a parting direction from the disc and in a rotation direction of the disc simultaneously, and
- a second spring which elastically pushes the other of the friction plate units in a parting direction from the disc and in an opposite direction to the rotation direction of the disc simultaneously;
- wherein the first spring and the second spring are substantially identical in configuration;
- and wherein the configuration of the first spring and the second spring is asymmetrical.
