Shock-absorbent snowplow mount

This disclosure concerns an invention relating generally to shock-absorbing devices for snowplows, and more specifically to shock-absorbing devices for assemblies which mount snowplow moldboards to their plowing vehicles. A snowplow mount is provided wherein a vehicle mount extending from the plowing vehicle is affixed to a reversing table, which is in turn rotatably connected to a plow moldboard at one or more pivots. One of the moldboard or the reversing table includes a bearing thereon, the bearing having a bearing bore defined therein. The other of the moldboard or the reversing table includes a pin which is elastically journalled within the bearing so that the pin and bearing may both rotate with respect to each other as well as translate with respect to each other in radial directions (i.e., in planes which are generally parallel to the axes of the pin and the bearing bore). Thus, loading of the moldboard allows the moldboard to translate with respect to the reversing table at the pivot as well as rotate. The reversing table is rotatably affixed to the vehicle mount with a linear actuator affixed therebetween so that actuation of the linear actuator will cause the reversing table to rotate with respect to the vehicle mount. The linear actuator is elastically mounted between the reversing table and vehicle mount so that the two may rotate a slight amount with respect to each other, with such rotation being elastically resisted. As a result, shock loading of the moldboard (and thus the reversing table) will not be readily transmitted to the linear actuator.
