Abstract: A bushing is provided which is arranged to be press fit into a bushing bore. The bushing is adapted to support a high level load which is unidirectional or which changes in direction through only a small angle. A rigid core in the bushing has a long rubber, or rubber-like, semicylinder bonded to one side of the outer surface thereof and has a number of uniformly spaced short rubber semicylinders bonded to the other side thereof. The short semicylinders have a greater wall thickness than the long semicylinder so that when the bushing is pressed into the bushing bore the space between the core and the wall of the bore is practically filled on the short semicylinder side. The long semicylinder operates in compression to support the high level load without exceeding the rubber endurance limits and therefore avoids the effects of internal deterioration in the rubber.

Abstract translation: 设置有衬套，其被布置成压配合到衬套孔中。 衬套适用于支撑单向的高级负载或仅通过小角度改变方向。 衬套中的刚性芯具有与其外表面的一侧结合的长橡胶或橡胶状半圆柱，并且具有多个均匀间隔开的短橡胶半圆柱，其与另一侧结合。 短半圆柱体具有比长半圆柱体更大的壁厚，使得当衬套被压入衬套孔中时，芯体和孔的壁之间的空间实际上填充在短半圆柱侧。 长半圆柱体在压缩状态下工作，不会超过橡胶耐力极限，从而避免橡胶内部变质的影响。

Abstract: An indexing and locking assembly for a two or three piece truck tire rim and which rim presents at least a base and a locking ring which is attached to the base to complete the same for mounting of the tire upon the rim. Means are provided on the base for indexing the ring with respect to the base, there also being means on the base and cooperating with the indexing means for locking the ring on the base. The indexing and locking means correct for disparaties such as out of roundness of the base or ring; physical deformation of the ring; or a mismatch between the ring and the base to which it is being attached, all to the end that the ring is properly placed upon and attached to the base and will not unexpectedly detach from the base during handling of the truck tire and rim whereby to cause injury to persons or damage to property.The index means is in the form of a pair of spaced apart tabs located on one side of a gap in the ring, which is presented by a transverse split in the ring, and the locking means is in the form of a lug positioned on the opposite side of the gap, the tabs and the lug being spaced apart along the gutter which circumscribes the base as a part of the conventional base assembly. The ring has a pair of notches therein for receiving the tabs when the ring is being attached to the base and a slot therein for receiving the lug, the tabs and the lug each presenting a ramp on the normally uppermost face thereof to aid in positioning the ring on the base, the tab proximal to the gap and the lug each having the wall thereof which is adjacent the gap beveled and tapered inwardly whereby to guide the ring onto the base and insure that the ring is fully and properly seated within the gutter of the base.
