Abstract
A leaf spring bearing for a vehicle with a transverse leaf spring. The leaf spring bearing includes an upper bearing block and a lower bearing block between which a portion of the transverse leaf spring can be interposed. Each bearing block is formed at least partially of elastic material and comprises an upper support surface and a lower support surface. At least one of the upper and lower bearing blocks has a bearing core and an insert positioned in the elastic material between the upper and lower support surfaces so as to define three layers of the elastic material within the at least one bearing block. At least one of the upper and lower bearing blocks has two support plates arranged either outside the elastic material or at least partially surrounded by the elastic material in the area of the upper and lower support surfaces of the bearing block.
