Abstract
The utility model discloses an engine front end gear train which comprises a first belt, a crankshaft pulley, a first generator pulley, a water pump pulley, a first idle wheel and a first tension wheel. The engine front end gear train is characterized by further comprising a second belt, a second tension wheel, a second generator pulley and a third generator pulley. The first idle wheel is a two-layer belt idle wheel. The first belt is sequentially wound around the crankshaft pulley, the first idle wheel, the first generator pulley, the water pump pulley and the first tension wheel. The second belt is sequentially wound around the first idle wheel, the third generator pulley, the second generator pulley and the second tension wheel.
Description
Technical field
The utility model relates to a kind of motor front-end wheel system.
Background technique
Present medium and heavy diesel engine, when supporting passenger vehicle, not only requires lightweightly, and volume is little, more requires the engine power output function complete, and integrated attachment is many.General conventional front-end train can only drive 1 or 2 generators, and therefore, in order to meet the passenger vehicle demand, the power of each generator must be enough large, and cost is high, and failure risk is large.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of motor front-end wheel system that can simultaneously drive a plurality of generators.
For solving the problems of the technologies described above, the utility model comprises the first belt, crank pulley, the first generator pulley, water pump pulley, the first idle pulley and the first Idle wheel, it is characterized in that it also comprises the second belt, the second Idle wheel, the second generator pulley and the 3rd generator pulley, described the first idle pulley is the double belt idle pulley, described the first belt is walked around crank pulley successively, the first idle pulley, the first generator pulley, water pump pulley, the first Idle wheel, described the second belt is walked around the first idle pulley successively, the 3rd generator pulley, the second generator pulley, the second Idle wheel.
After adopting said structure, the utility model can be according to user's request, realize any selection installation between one, two, three generators, greatly increased supporting scope, adopt the double belt idle pulley as driver element simultaneously, make crank pulley become the single belt transmission, shortened the motor lower length.In the situation that the generator total output is identical, three small power generators replace one or two high-power generator, and cost will reduce greatly, and all damage so long as not all generators, just can not cause the car load paralysis, have improved the reliability of car load.
Be provided with the second idle pulley between described the first idle pulley and the first generator pulley, the second idle pulley is positioned at the outside of the first belt.
Described the first Idle wheel and the second Idle wheel are Idle wheel in the same way.
Described the first belt is poly Vbelt.
Described the second belt is poly Vbelt.
The accompanying drawing explanation
Below in conjunction with the drawings and the specific embodiments, the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, motor front-end wheel system comprises and is positioned at the first belt 2, crank pulley 6, the first generator pulley 1, water pump pulley 4, the first idle pulley 11, the first Idle wheel 5, the second belt 9, the second Idle wheel 7, the second generator pulley 8 and the 3rd generator pulley 10, the first belt 2 and the second belt 9 all adopt poly Vbelt, the first Idle wheel 5 and the second Idle wheel 7 are Idle wheel in the same way, Idle wheel turns round the automatic tensioner that axle bed and belt pulley are distributed in the swing arm homonymy in the same way, the first idle pulley 11 is the double belt idle pulley, the first belt 2 is walked around crank pulley 6 successively, the first idle pulley 11, the first generator pulley 1, water pump pulley 4, the first Idle wheel 5, described the second belt 9 is walked around the first idle pulley 11 successively, the 3rd generator pulley 10, the second generator pulley 8, the second Idle wheel 7.
For guaranteeing the cornerite of the first idle pulley 11, be provided with the outside that the second idle pulley 3, the second idle pulleys 3 are positioned at the first belt 2 between the first idle pulley 11 and the first generator pulley 1, by being set, the second idle pulley 3 can improve the stationarity of transmission, prevent belt slippage.
The utility model adopts two-layer belt transmission to drive three generators.First layer belt transmission wherein: comprise the crank pulley 6 as the train power output unit, by the first belt 2 by transmission of power to the first idle pulley 11, then be passed to the second idle pulley 3, then pass to the first generator, then pass to water pump pulley 4, finally pass to the first Idle wheel 5.Second layer belt transmission: comprise the first idle pulley 11 as the power output unit of this layer of transmission, give the 3rd generator by the second belt 9 by transmission of power, then pass to the second generator, then pass to the second Idle wheel 7, the second Idle wheel 7 guarantees this train poly Vbelt energy auto-tensioning, improves the functional reliability of train.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model.Previous embodiment has been described in detail the utility model, and for a person skilled in the art, its technological scheme that still can put down in writing aforementioned each embodiment is modified, or part technical characteristics wherein is equal to replacement.In every case within inventive concept scope of the present utility model, any modification of making, be equal to replacement, improvement etc., within all being included in protection domain of the present utility model.
