Connected system of mining vehicle engine and gearbox

Abstract

The invention discloses a connected system of a mining vehicle engine and a gearbox. The connected system comprises an engine and a gearbox, wherein a bearing seat shell is arranged behind the engine, the engine output shaft is extended in the bearing seat shell, a driven disc assembly is arranged in the bearing seat shell, and the outside of the driven disc assembly is correspondingly provided with a clutch pressure plate assembly; the engine output shaft passes through the driven disc assembly and the clutch pressure plate assembly, gets out and extends onto the bearing seat at the outside of the bearing seat shell; the outside of the bearing seat is connected with a drive shaft 1, and a constant speed drive system is connected between the drive shaft 1 and the gearbox. The driven disc assembly, the clutch pressure plate assembly and the constant speed drive system are organically combined into one to form a connected system of the mining vehicle engine and the gearbox according to the invention; the connected system of the mining vehicle engine and the gearbox has the advantages that the structure is simple, the manufacture and maintenance are convenient, the reliability is high, and the max compaction power can reach 55,000N.m, the greater torque can be transferred, the influence of the vibration of the drive system on vehicle parts is reduced, the service life of the drive system is prolonged, and the vehicle cost is lowered to the maximum extent.

Description

technical field [0001] The invention relates to a mining vehicle, in particular to a connection system between a mining vehicle engine and a gearbox. Background technique [0002] The front transmission system of mining vehicles mostly adopts the composition of flexible disc + output flange + non-constant velocity transmission shaft. The non-constant velocity transmission shaft has a heavy transmission shaft tube, which has its own waste; at the same time, because the mining vehicle has been running at a low speed, the transmission accuracy of the non-constant velocity transmission shaft cannot be realized (mainly the non-constant velocity transmission shaft pair The installation requirement is higher than that of the constant velocity transmission shaft, which has a great impact on the vibration of the transmission system), resulting in the waste of the entire transmission system and the failure to maximize the output power of the engine (the transmission efficiency of the ...

[0002] The front transmission system of mining vehicles mostly adopts the composition of flexible disc + output flange + non-constant velocity transmission shaft. The non-constant velocity transmission shaft has a heavy transmission shaft tube, which has its own waste; at the same time, because the mining vehicle has been running at a low speed, the transmission accuracy of the non-constant velocity transmission shaft cannot be realized (mainly the non-constant velocity transmission shaft pair The installation requirement is higher than that of the constant velocity transmission shaft, which has a great impact on the vibration of the transmission system), resulting in the waste of the entire transmission system and the failure to maximize the output power of the engine (the transmission efficiency of the non-constant velocity transmission shaft is higher than that of the constant velocity transmission shaft Low)

[0003] The front transmission system of mine truck gearbox adopts flexible disc connection or hard connection, that is, the output mode of the engine is flexible disc connection or hard connection. Due to the harsh working environment of mining vehicles, although the flexible disc connection can protect The output of the engine is limited, but the output power is limited, which is a waste of power for a mining truck that pulls hundreds of tons at a time; although the rigid connection can fully output the power of the engine, it hurts the engine, and the gain outweighs the gain

[0004] After the flange is combined, the entire product has a complex structure and heavy weight. For the entire mining vehicle, the combination of the transmission system is the lifeblood of the entire vehicle, especially for mining vehicles exceeding 50-100 tons, the structure of the transmission system is complex and unreasonable. , not only troublesome in maintenance and use, but also not conducive to energy saving
