Mine anti-explosion diesel engine railless free-wheeled vehicle front axle suspension system

Abstract

The invention relates to a mine anti-explosion diesel engine railless free-wheeled vehicle front axle suspension system. The front axle is arranged on a left push rod and a right push rod one end of which are hinged with frame, the left push rod and the right push rod are respectively provided with a left spring support and a right spring support, the left spring support and the right spring support are respectively provided with a front pressure spring and a front damping rubber, and meanwhile the front axle is also connected with the frame by two front axle steel wire ropes and two damping devices which are connected thereon; wherein the hinged position of the frame and the front axle is provided with a front axle tierod, and a rubber hinge is adopted at the hinged position between the two ends of the front axle as well as the frame and the front axle. The hinged position of the left push rod and right push rod as well as the frame adopts a rubber hinge. The hinged position of the left push rod and right push rod as well as the front axle adopts a polyurethane elastic hinge. The invention avoids collision between parts, stress is more scientific, damping effect is better; the stress of the damping spring is more reasonable, and the service life of front axle splint, connecting bolt and spring is improved.

Description

technical field [0001] The invention relates to the manufacture of underground vehicles in coal mines, and in more detail relates to a front axle suspension device for mine explosion-proof diesel engine trackless rubber-tyred vehicles. Background technique [0002] Mining explosion-proof diesel engine trackless rubber-tyred vehicles are used in the transportation of personnel and materials in large coal mines. Due to the harsh working conditions in coal mines, the reliability of each component of the rubber-tyred vehicle is strictly required, and the reliability and service life of the suspension mode of the rubber-tyred vehicle axle , stability, passability and other indicators are particularly demanding. At present, the front axle suspension device of the existing technology of various domestic explosion-proof diesel engine trackless rubber-tyred vehicles generally adopts the structure of rigid connection between the drive axle and the frame. The results of use show that w...

[0002] Mining explosion-proof diesel engine trackless rubber-tyred vehicles are used in the transportation of personnel and materials in large coal mines. Due to the harsh working conditions in coal mines, the reliability of each component of the rubber-tyred vehicle is strictly required, and the reliability and service life of the suspension mode of the rubber-tyred vehicle axle , stability, passability and other indicators are particularly demanding. At present, the front axle suspension device of the existing technology of various domestic explosion-proof diesel engine trackless rubber-tyred vehicles generally adopts the structure of rigid connection between the drive axle and the frame. The results of use show that when the rubber-tyred vehicle is running, because the chassis of the rubber-tyred vehicle cannot adapt to the undulations of the underground ground in the coal mine, it causes a lot of bumps, and there are cracks in the front axle splint, connecting bolts, springs, etc.
