Jounce bumper

A jounce bumper comprising:

• a main body including a first polymeric material;
• and
• an insert integral with the main body, the insert including a second polymeric material that is more rigid than the first polymeric material, the insert including:
• a first plate, a second plate, and a third plate each defining outer apertures spaced outward from a longitudinal axis of the jounce bumper, the outer apertures are aligned in a direction parallel to the longitudinal axis, the first polymeric material of the main body fills the outer apertures;
• a first connecting lattice between the first plate and the second plate;
• and
• a second connecting lattice between the second plate and the third plate;
• wherein the first polymeric material of the main body is between the first plate and the second plate, between the second plate and the third plate, within the first connecting lattice, and within the second connecting lattice.

A jounce bumper comprising:

• a main body including microcellular urethane;
• and
• an insert integral with the main body, the insert including thermoplastic urethane and the following:
• a first plate, a second plate, and a third plate each defining outer apertures spaced apart from a longitudinal axis of the jounce bumper, the outer apertures are aligned in a direction parallel to the longitudinal axis, the microcellular urethane of the main body fills the outer apertures;
• a first connecting lattice extending between an outer periphery of both the first plate and the second plate, the first connecting lattice defining a plurality of first openings arranged about the insert, the plurality of first openings filled with the microcellular urethane of the main body;
• and
• a second connecting lattice extending between an outer periphery of both the second plate and the third plate, the second connecting lattice defining a plurality of second openings arranged about the insert, the plurality of second openings filled with the microcellular urethane of the main body;
• and
• a center aperture extending along the longitudinal axis of the jounce bumper, the center aperture defined by each of the main body, the first plate, the second plate, and the third plate;
• wherein the microcellular urethane of the main body is between the first plate and the second plate and between the second plate and the third plate.
