ABSTRACT:
A front-mounted, shock-absorbing attachment means for a snowplow on a vehicle, comprising a substantially vertical front plate with fastening means for detachable mounting of the snowplow. The upper section of the front plate is pivotally secured to the frame of the vehicle, and its lower section, via buffer cylinders adjustable in length and pivotally fastened at one end thereof to the front plate, is supported against the front wheel axle of the vehicle by means of respective brackets which are rigidly clamped to respective brackets which are rigidly clamped to respective leaf spring assemblies in front of the front wheel axle and which rest directly or indirectly against the leaf spring assembly. The point of attachment of the buffer cylinder on the bracket thus is located forward of the front wheel axle and lower than the leaf spring assembly, and when the buffer cylinders are subjected to loading from the front plate, said point will be caused to pivot backwardly about a point of contact on the front wheel axle and thereby bend the spring assembly downwardly in front of the front wheel axle. This will cause the front plate to pivot backwardly somewhat about its pivotal supports on the vehicle frame. This relieves shocks on the vehicle frame caused by the possible impact of the snowplow against obstructions in the road, in addition to the shock absorption that occurs upon compression of the buffer cylinder. The front plate can be adjusted to the desired position by means of the adjustable-length buffer cylinders, such that when the front plate has been pivoted backwardly as far as possible, it will assume an approximately vertical position.
