Prefab model 1/35 truck ZIL-135 ZIL-135 Trumpeter 01073 Initially, ZIL-135 was developed as an artillery towing truck in the Special Design Bureau of ZIL under the leadership of V. A. Grachov in the early 1960s. The machine is equipped with two ZIL-123F engines with a capacity of 120 hp. each, installed behind the cabin (ZIL-375 engines were used on subsequent car models). Each engine turned the wheels of its side, which provided additional reliability. Taking into account the use of low-pressure tires, as well as due to the desire to reduce the weight of the machine as much as possible, the designers decided to abandon the elastic suspension as such, later on the 135L/LM models to eliminate galloping (longitudinal rocking), which distinguished the previous cars of the 135th family, it was decided turn the independent torsion suspension with hydraulic shock absorbers on the wheels of the extreme axles, while maintaining a rigid attachment to the frame of the two middle axles. The wheels of the extreme axles are swivel. Other parameters, including dimensions, load capacity, suspension design, floatability, wheelbase, etc., varied widely from one model to another. The cabin was made of fiberglass to lighten the machine and thus increase the payload.
