Abstract
A static vehicle wheel balancing head has a base mounting an upright post terminating in a concave spherical anvil surface that supports three support balls. The balancing head has the usual means for mounting a wheel and has a single socket mounted pivot ball that is supported by the three support balls. The pivot ball is preloaded by a Belleville washer assembly and the preload is adjustable by a threaded plug. Opposed faces on the post and the balancing head are normally spaced by a small distance. Under shock loads, the pivot ball on the balancing head is forced up into its socket, compressing the Belleville washers. This brings the opposed faces into engagement and protects the pivot ball assembly.
