Totally-closed power transmission device used for coal mine explosion-proof electric rubber-wheel vehicle

Abstract

The invention belongs to the technical field of designing and manufacturing of coal mine underground trackless auxiliary equipment, and particularly relates to a totally-closed power transmission device used for a coal mine explosion-proof electric rubber-wheel vehicle. The device comprises a wheel edge transmission speed reduction mechanism, a travel braking mechanism and a parking braking mechanism; the wheel edge transmission speed reduction mechanism is connected with an explosion-proof motor through a coupler, the wheel edge transmission speed reduction mechanism is connected with the travel braking mechanism and the parking braking mechanism, an output shaft of the explosion-proof motor, the coupler, the transmission speed reduction mechanism, the travel braking mechanism and the parking braking mechanism are longitudinally connected in series and fixed and are located on the same central axis, the totally-closed modular combined integrated design is adopted, and the device has the beneficial effects of being compact in structure, convenient to dismount, mount and maintain, pollution-resisting, reliable in explosion-proof property, stable in property, energy-saving, environment-friendly, good in braking cooling effect and the like, and the traveling safety of the rubber-wheel vehicle can be improved.

Description

technical field [0001] The invention belongs to the technical field of design and manufacture of underground trackless auxiliary equipment in coal mines, in particular to a fully enclosed power transmission device for explosion-proof electric rubber-tyred vehicles in coal mines. Background technique [0002] With the high-yield and high-efficiency development of my country's coal mines, especially large and medium-sized coal mines, a large number of trackless rubber-tyred vehicles powered by explosion-proof diesel engines have been put into use, which has achieved great results in reducing personnel and increasing efficiency, improving production efficiency, improving coal mine safety, and reducing accidents. However, a large number of explosion-proof diesel engine vehicles have been put into use in large quantities underground, gradually exposing the harmful exhaust gas and loud noise of diesel engines that affect the physical and mental health of underground personnel, high ...

AI Technical Summary

Problems solved by technology

Explosion-proof battery rubber-tyred vehicles are mostly modified on diesel vehicles, and the power transmission system still uses the traditional structure, mainly composed of explosion-proof clutches, gearboxes, transmission shafts, drive axles, etc. The components of this traditional transmission system are relatively complicated. , the transmission chain is long and occupies a large space, which is not conducive to the flexible layout of the vehicle. At the same time, due to the structural constraints of the transmission system, the ground clearance of the vehicle is small, which limits the vehicle's passing ability and off-road ability
