Kirovets embodies all of the best large-tractor design principles; equal-sized wheels, a massive articulated frame, ballasted for ideal weight distribution, and auto-locking axles. These design features are the key to the tractor’s unsurpassed tractive performance; up to 10% better than conventional designs of equivalent engine power.
The frame provides the structural platform of the tractor; a mounting for all of its power generating, transmitting and controlling parts. With ballast and a full fuel load, a Kirovets can weigh almost twenty tonnes. The frame needs to be strong enough to support the mechanical parts and absorb all the working loads, whether imposed by towed or attached implements or by difficult terrain. The frame must be built to endure, without failure or fatigue, a working life that may extend to more than forty years.
The Kirovets frame is a solidly made all-enclosed box section steel weldment. Frame parts are cut and folded, assembled, carefully welded and precision machined. A massive centre pivot articulates the front and rear parts of the frame through a trunnion yoke with large, fully sealed bearing surfaces. This yoke provides for relative movement of the front and rear frame elements with two degrees of freedom; +/-32o on the vertical axis and +/-16o on the longitudinal axis. It is this design feature that gives articulated tractors their advantageous characteristics; the ability to maintain all-wheel ground contact on undulating terrain, a compact turn radius and a steering geometry that, unlike fixed-frame front wheel steered machines, ensures that the leading and trailing wheels follow the same path.
The power unit used in the Kirovets K-7M is the Mercedes Benz OM 460 LA, a 12.82 litre in-line six cylinder turbo-diesel with electronic engine management for superior fuel economy and emissions performance. The engine is configured to Euro IIIA standard and does not require the use of Adblue® or a DPF. The engine has a noise optimised cast iron block with wet cylinder liners and separate four-valve cylinder heads, oil-cooled aluminium pistons, precision forged connecting rods and an induction-hardened seven-bearing crankshaft. The oil cooler is integrated within the crankcase. The Mercedes Benz engine offers exceptional quality, durability and fuel economy (205 g/kWh), thoroughly proven throughout the world in numerous agricultural and transportation equipment applications.
The Kirovets K-7 transmission combines the simplicity and robustness of a parallel shaft constant mesh mechanical transmission design with pneumatically controlled actuation for ease of operation. Sixteen forward and eight reverse speeds are available in four and two operating modes respectively. Within each selected mode, speeds can be shifted under power, without interruption, by hydraulically actuating the appropriate clutch pack. The clutch packs use multi-disc assemblies with alternating steel and ceramic plates. Modes are engaged by axially sliding sleeve gears on the middle and bottom shafts. Gears, forward and reverse, are selected by a joystick control. Modes and 2WD or 4WD are selected by switches and engaged by pneumatic actuators. An electronic control module protects the transmission from operator error. The transmission is pressure lubricated and has a front mounted oil cooler. The Kirovets design is thoroughly proven, reliable and durable. Spur gears are used throughout for power transmission efficiency and the elimination of axial thrust loads within the transmission casing. Gear wheels are processed from in-house cast and forged blanks on CNC gear-cutting machines. After heat treatment, tooth profiles are finish ground to precise final dimensions and geometry (DIN class 7 & 8). Transmissions are hand assembled by skilled technicians and thoroughly bench tested prior to installation on the tractor frame.
