The working clearance height of a high-clearance vehicle is normally established by four main suspension spindles that are respectively received for reciprocating within upright journals provided at the opposite ends of front and rear axle assemblies of the vehicle main frame, with the bottom end each of the main spindles being received in a bore at the top of an associated wheel motor housing that serves also as a wheel hub mounting bracket. In order to increase the working clearance height of the vehicle, an optional elongate spacer assembly is mounted between the bottom of each elongate main suspension spindle and the associated wheel motor housing. Each main suspension spindle is inclined slightly outwardly relative to a vertical plane extending in the direction of travel of the vehicle and, in order for the spacing between tires at opposite sides of the vehicle to remain the same, with or without the usage of the spacer assemblies, each spacer assembly includes a coupler spindle extending parallel to, and offset inwardly from, a pivot axis of the associated main suspension spindle by a distance calculated to result in the desired tire spacing, this coupler spindle being received in the bore at the top of the associated wheel motor housing.

The invention claimed is: 1. In a suspension assembly for a high-clearance vehicle having a forward direction of travel and a first operating clearance height, the suspension assembly including an upright spindle journal fixed to a frame of said vehicle, a main suspension spindle received in said journal for at least sliding axially within said journal, and a wheel hub mounting member being coupled to a lower end of said main suspension spindle, the improvement comprising; a spacer assembly for increasing said clearance height being optionally connected between said lower end of said main suspension spindle and said wheel hub mounting member, said spacer assembly including upper and lower ends respectively provided with upper and lower bores and a coupler spindle having an upper end located within said lower bore, said upper bore receiving a bottom end of said main suspension spindle; a first coupler assembly fixing said spacer assembly for movement with said main suspension spindle; said wheel hub mounting member having a third bore sized identically to said first bore located in an upper end thereof; said coupler spindle having a bottom end section projecting downwardly from said spacer assembly and being received in said third bore, and second and third coupler assemblies respectively fixing said coupler spindle to said spacer assembly and to said wheel hub mounting member. 2. The suspension assembly, as defined in claim 1, wherein said upper and lower bores of said spacer assembly are identically sized. 3. The suspension assembly, as defined in claim 1, wherein said upright spindle journal is inclined outwardly from a vertical plane extending parallel to said direction of travel; and said lower bore of said spacer assembly extending parallel to said upper bore and being offset inwardly from said upper bore by a distance which compensates for the spacing between the bottom of the main suspension spindle and the hub mounting member so that a wheel mounted to the hub when no spacer assembly is used will contact the ground in the same location as it does when the spacer assembly is used. 4. The suspension assembly, as defined in claim 1, wherein the spacer assembly includes separate upper and lower castings which are bolted together. 5. The suspension assembly, as defined in claim 2 wherein said spacer assembly includes separate upper and lower castings which are coupled together; said upper casting being provided with said upper bore and said lower casting being provided with said lower bore. 6. The suspension assembly, as defined in claim 3, wherein said spacer assembly includes upper and lower castings which are coupled together.
