Abstract

The invention relates to a U-shaped buffering supporting base of a diesel engine of an armoured vehicle. The U-shaped buffering supporting base comprises a main vibration absorber 3, a bottom board 6, an upper U-shaped support 2, a lower U-shaped support 4, a nut 1, lower connection bolts 5, upper connection bolts 7 and fixing bolts 8. The main vibration absorber 3 is fixedly connected with the upper U-shaped support 2 through the nut 1, the main vibration absorber 3 is fixedly connected with the lower U-shaped support 4 through the upper connection bolts 7, the upper U-shaped support 2 is connected with the diesel engine through the fixing bolts 8, and the lower U-shaped support 4 is fixedly connected with the bottom board 6 through the lower connection bolts 5. By the adoption of a buffering structure composed of the main vibration absorber 3, the upper U-shaped support 2 and the lower U-shaped support 4, the resonance peak can be effectively restricted, and the good vibration isolation buffering effect is obtained. The upper U-shaped support 2 is provided with a limiting device, and therefore the oversize amplitude of the diesel engine caused by overload is prevented. By means of the U-shaped buffering supporting base, support positioning is accurate, the buffering function is achieved better, and working reliability of the whole machine is improved.

Description

technical field [0001] The invention belongs to the technical field of diesel engines for armored vehicles, and in particular relates to a buffer support for diesel engines. Background technique [0002] The combustion pressure, reciprocating inertial force and rolling moment of the diesel engine will cause the diesel engine to vibrate greatly, and the vibration will be transmitted to the vehicle chassis through the support, causing the vehicle to vibrate. For the armored vehicle diesel engine, due to the bad road conditions when it is used, the vibration caused by the bumping of the vehicle is particularly serious. Vibration directly affects the reliability of the diesel engine and its internal high-precision electronic equipment, as well as the comfort and durability of the vehicle. In addition, when an armored vehicle fires a cannon, it produces a powerful impact force, which is transmitted to the diesel engine through the support, which will cause damage to the diesel e...
