Abstract
The invention provides a novel mining vehicle elastic coupling comprising an engine flywheel located in a flywheel shell. An outer shell is connected in the flywheel shell. The engine flywheel achieves output via a power output shaft, which is fixed in a bearing base via a bearing at an output portion of the outer shell, and then output is performed. The connecting face, facing the power output shaft direction, of the engine flywheel is successively provided with a friction sheet, a driven wheel assembly, a diaphragm spring and a pressure plate, wherein the friction sheet, the driven wheel assembly, the diaphragm spring and the pressure plate are connected with the engine flywheel through the power output shaft to form one coupling. The novel mining vehicle elastic coupling can achieve torque transmission of large-power engines without slip, and can eliminate radial, axial and angular impact of a whole power system effectively through the diaphragm spring in the pressure plate and a damping spring in a driven plate, thereby achieving stable transmission of power.
Description
Technical field
The present invention relates to the drive system of mine truck, specifically a kind of new type mining vehicle spring shaft coupling.
Background technology
Mining automobile engine-Side Gearbox Transmission System is connected by yielding coupling.Due to mine truck working environment it is severe, at present country's mine car adopts elasticity of import shaft coupling substantially, the basic function of shaft coupling is accomplished by make up radially, axially, angular deviation, absorb impact endurance test shock, turn round the unfavorable loads such as shake, so the selection of shaft coupling is all elastomeric elastomeric material. by the symmetrical block rubber of circumference, complete shock absorption when reversing to dynamical system, required according to different power-transmission systems, select the highly elastic material of difference ShoreShi hardness, different dynamic torsional rigidities are directed to accordingly. its structure and material are complicated, it is expensive, later maintenance inconvenience, and service life is shorter, general 1-2 needs to change.
In examining -Application number：201510069309.0 the applying date：The connection system of 2015-02-11, mining car engine and change speed gear box, including electromotor and change speed gear box, bearing block housing is provided with after electromotor, engine output shaft extends in bearing block housing, and clutch drived disk assy is provided with bearing block housing, and clutch cover and plate assembly is correspondingly provided with outside clutch drived disk assy；Engine output shaft runs through clutch drived disk assy and clutch cover and plate assembly and stretches out on the bearing block outside bearing block housing；Bearing block is externally connected with one axle of transmission, and reconnecting between one axle of transmission and change speed gear box has constant speed drive's system.Clutch drived disk assy, clutch cover and plate assembly and constant speed drive's system are organically integrated and are collectively forming the connection system of mining car engine and change speed gear box by the present invention, it is simple structure, manufacture, easy to maintenance, reliability is high, maximum thrust can reach 55000N.m, more high pulling torque can be transmitted, reduce impact of the driveline vibrations to car load part, improve the drive system life-span, can to greatest extent reduce integral vehicle cost.
Above-mentioned patent application uses clutch drived disk assy, clutch cover and plate assembly and constant speed drive's system and is organically integrated, but its function mainly uses the principle of clutch, and clutch almost takes less than in mine truck, because can not possibly exist using clutch come speed change, the gear shift mode that full automatic throttle can only be adopted to increase, so clutch is not just used, material is wasted.
Due to the intrinsic operating characteristic of electromotor, the especially high-power engine provisioned in mine truck, during power output, unbalanced and periodic reciprocating impact is there is, it is twisting vibration to show to direction of rotation.
Simultaneously because mining car engine needs the smooth transfer of power, radially, axially and angularly impacting for whole dynamical system is eliminated.
The content of the invention
Smooth transfer in order to realize power of the invention, eliminates radially, axially and angularly impacting for whole dynamical system, a kind of new type mining vehicle spring shaft coupling of spy's proposition.
The technical scheme is that for this, a kind of new type mining vehicle spring shaft coupling, including engine flywheel, engine flywheel is mounted in bell housing, shell is also associated with bell housing, engine flywheel is exported by power output shaft, and wherein power output shaft is fixed in bearing block at the output of shell by bearing, then export, it is characterised in that：Described engine flywheel is sequentially provided with friction plate, driven wheel assembly, diaphragm spring, platen towards on the joint face of power output direction of principal axis, and described friction plate, driven wheel assembly, diaphragm spring, platen are connected as a shaft coupling by power output shaft and engine flywheel.
Further it is improved by：Damping spring is provided with driven wheel assembly.
Further it is improved by：Friction plate two sides is respectively and fixedly provided with polymer ceramic copper-based material.
Further it is improved by：Driven wheel assembly is provided with spline housing connection corresponding with power output shaft.
Beneficial effect：
The present invention is after general assembly is finished; under fixed diaphragm spring effect in platen; clutch drived disk assy is tightly fitted with engine flywheel by middle friction plate; the moment of torsion transmission of high-power engine can be realized and will not occur skidding; there is shell to be fixedly connected with flywheel shell of engine in outer end; the protection to whole system is realized under the severe operating mode in mine; housing center is provided with the non-maintaining bearing of high speed; support is played a part of to power output shaft; simultaneously shell lower section is provided with maintenance observation panel, rational in infrastructure；Diaphragm spring and the damping spring in clutch plate in platen can be utilized effectively to eliminate radially, axially and angularly impacting for whole dynamical system, realize the smooth transfer of power.
Friction plate two sides is respectively and fixedly provided with polymer ceramic copper-based material, it is possible to achieve the moment of torsion of high-power engine transmits and will not occur skidding.
Driven disk center is provided with spline housing, transfers power to output shaft, so as to the power for completing whole system is transmitted.
Compared with traditional clutch configuration, the new structure cancels separating mechanism, keeps clutch plate to fit with the continuous close of flywheel（I.e. diaphragm spring is constantly in impaction state）, so as to ensure that it is steady and lasting in transmittance process that whole power is transmitted.
1. compared with traditional elastic shaft coupling, cost reduces by 70%, and service life improves 50%.
