Joint assembly for motion simulator

A motion simulator comprising:

• an output;
• at least one linear actuator between the output and a support structure;
• at least one joint assembly between the at least one linear actuator, and one of the output and the support structure, the joint assembly comprising
• a ball portion connected to either the at least one linear actuator, or one of the output and the support structure;
• a socket connected to either the at least one linear actuator, or one of the output and the support structure complementary to that connected to the ball portion, and comprising
• a socket base,
• a socket cover, and
• a spherical joint cavity within the assembled socket base and socket cover to receive the ball portion to form a spherical joint;
• at least one biasing member in the joint assembly;
• and
• a clamp clamping the socket base to the socket cover such that the at least one biasing member biases the socket base and the socket cover toward one another.
