Description

THE METHOD OF MOUNTING OF THE AUXILIARY POWER UNIT ON A CATERPILLAR VEHICLE,
The subject of the invention is the method of mounting of the Auxiliary Power Unit (APU) on a caterpillar vehicle. APU constitutes an additional power source enabling the vehicle's deck systems to operate when the main engine is switched off. The further described way of mounting of the APU solves the problem of electrical power deficiency and contributes to the economical operation of the main engine.
The solutions of fixing the Auxiliary Power Units on caterpillar vehicles are widely known. Their aim is to secure the proper conditions for the power supply to the basic deck systems while the main engine is switched off.
Contemporary solutions for newly designed caterpillar vehicles entirely rely on a permanent assembly of deck power units inside the transmission-engine compartment of a vehicle's hull. Russian T-80 has an additional (turbine-driven) power unit mounted externally on the right mudguard of the vehicle. Such external assembly is used mainly due to the lack of sufficient space inside the vehicle's hull.
Additional electrical power source mounted inside the vehicle is also known for its Polish notification Al 302091.
The external mounting of auxiliary power units in caterpillar vehicles, however, is usually strongly limited by collisions with various special equipment, already mounted outside the hull.
The aim of this invention is to deploy the APU on a caterpillar vehicle in such a way that the increase of electrical power supply with the main engine switched off would be ensured with minimal collision with the outside mounted equipment and without affecting the operation of the basic vehicle's systems.
The essence of the invention is that the APU is mounted on the rear part of the vehicle's hull on a special stand, in-between the fuel barrels. The APU can be placed in two positions: upper - transport position and lower - operational position. The special stand is constructed of upper brackets, and extension jibs with lower brackets. Furthermore, the upper brackets and the extension jibs are permanently fixed to a crossbar directly mounted to the brackets of the hull. It is very practical that the APU has a mechanical lock for two positions: upper- transport position and lower - operational position.
It is also very practical that the additional special stand for the APU is mounted to the brackets of the hull, which are normally used as fixing elements of the fuel barrels. Moreover, the APU is fixed to the hanger which is fixed to the upper brackets by means of upper-balance levers seated on upper grips (from the side of the hanger) and is also fixed to the lower balance levers seated on lower grips (from the side of the hanger). Blocking of the APU in upper and in lower position is performed by means of upper switch-lock 15 [seated in grips 14 of the hanger 5] and lower switch-lock, respectively.
It is very functional when the weight of APU is compensated by means of resilient torsional element mounted rotationally in upper brackets. The resilient torsional element must constitute, at the same time, the turning axis stiffly connected with the upper balance levers and must be stiffly fixed at the end of the cross-bar by means of a grip.
The subject of invention and its realisation are presented, as an example, in Fig. 1-8. Fig. 1 and Fig. 3 present the method of mounting of the APU on a caterpillar vehicle in side (end) views in transport (Fig. 1) and operational (Fig. 3) position; Fig. 2 and Fig. 4 show the mounting of the APU in from-back views in transport (Fig. 2) and operational (Fig. 4) position; Fig. 5 and Fig. 6 show the mounting of the APU in from- above views in transport (Fig. 5) and operational (Fig. 6) position; Fig.7 and Fig. 8 present the mounting of the APU in axonometric views in transport (Fig. 7) and in operational (Fig. 8) position.
The method of mounting the Auxiliary Power Unit on a caterpillar vehicle is presented in Fig.1-8. The Auxiliary Power Unit APU 4 is mounted on the caterpillar vehicle in the back part of its hull 1 on the additional stand 3_, in-between the fuel barrels. The additional stand 3_ is mounted to the (already existent on the hull) brackets 2. The brackets 2 are used as a support for mounting grips 26 with assembly clamps under the fuel barrels 25_. The additional stand 3_ of the APU is built of upper brackets K) and the extension jibs 7 with lower brackets H. The upper brackets JhO and the extension jibs 1_ are permanently fixed to a cross-bar 6 directly mounted to the brackets 2 of the hull 1 of the caterpillar vehicle. The Auxiliary Power Unit 4 is fixed to the hanger 5_, which is joined with the additional stand by means of upper balance levers j_2 and lower balance levers J_3. The balance levers 12 and 13 are seated (from the side of the hanger 5) on pins 20 in upper grips £ and lower grips 9, respectively. From the side of the additional stand 3, the upper balance levers \2 and lower balance levers J_3 are mounted to the upper bracket JO [by means of a resilient torsional bar 18] and the lower bracket JJ_ of the extension jib 7 by means of a pin YL, respectively.
Blocking of the APU 4 in upper position (transport) and in lower position (operational) is performed by means of upper switch-lock 15 [seated in grips .14 of the hanger 5J or lower switch-lock 16 [seated in the upper balance levers \2\, respectively. The switch-locks 15 and j_6 are made in the form of a pin (manually operated), with a return spring.
The weight of the APU 4 is compensated by means of resilient torsion bar J_8, which is rotationally mounted in upper brackets Jj). The torsion bar IS. constitutes, at the same time, the turning axis stiffly connected with the upper balance levers \2 and it is stiffly fixed in one end to the cross-bar 6 by means of a grip Ij).
The resilient torsion bar 1_8 makes possible the APU to be easily raised and lowered by the vehicle crew, without the necessity of using any additional supporting equipment. The fuel barrels 25 [together with fuel ferrules 23. pumping the fuel to the tanks] are mounted to the brackets 26, which are screwed by the clamping bolts 27 to the cross-bar 6.
The Auxiliary Power Unit 4 is able to operate in upper (transport) position as well as in the lower (operational) position. Before activating the APU 4 it is required to open the sealing cover 22 of the inlet 21_ of cooling air and the sealing cover 23_ of the outlet of the air. The access to the manual operation/service of the APU 4 and to the control of its parameters is possible after opening the inspection/revision cover 24^
The implemented solution of the invention ensures an increase of the achievable power of electrical energy deck sources without operating the main engine and without any changes of technical and tactical parameters of the caterpillar vehicle.
