Abstract:
1. A radial stiffness contact analyzer having a stationary portion and a rotating portion on which a tire is mounted, the radial stiffness contact analyzer comprising: a catch disposed on the rotating portion, the catch having a first recess including an inclined portion and a lateral wall; a guide block disposed on the stationary portion, the guide block including a second recess; a lock wedge that is slidably disposed within the second recess, the lock wedge having a first inclined surface that corresponds to the inclined portion of the catch, a second inclined surface and a contact surface; a jam wedge that is slidably disposed within the second recess, the jam wedge having an inclined surface corresponding to the second inclined surface of the lock wedge; and wherein, in a locked state, the lock wedge is urged towards the catch so that a portion of the lock wedge is disposed in the recess of the catch so that the first inclined surface of the lock wedge is in contact with the inclined portion of the catch and the contact surface of the lock wedge is in contact with the lateral wall of the catch, and the jam wedge is urged towards the catch so that the inclined surface of the jam wedge is in contact with the second inclined surface of the lock wedge, thereby restricting the rotation of the rotating portion.
