Apparatus for determining shape of contact patch and contact pressure of tires
First Claim
1. An apparatus for determining the shape of contact patch of a tire and the contact pressure thereof characterized in that the apparatus comprises:
- a contact member made of a transparent material,a pressing unit for pressing the outer peripheral surface of the tire against the contact member,a sheet having elastic projections arranged regularly on one surface thereof and uniformly distributed thereover, andan observation device for observing through the contact member the projections as deformed when the tire is pressed against the contact member with the sheet interposed therebetween and with the projections thereof facing the contact member.

Abstract
An apparatus for determining the shape of contact patch and the contact pressure of a tire comprises a contact member made of a transparent material, a pressing unit for pressing the outer peripheral surface of the tire against the contact member, a sheet having elastic projections arranged regularly on one surface thereof and uniformly distributed thereover, and an observation device for observing through the contact member the projections as deformed when the tire is pressed against the contact member with the sheet interposed therebetween and with the projections thereof facing the contact member. The shape of contact patch and contact pressure of the tire can be determined by observing deformed projections by the device.
