The model utility content
The utility model technical problem to be solved is: provide a kind of WP7 bus engine air-conditioning to carry driving mechanism, the car load vibration and noise is big to solve, air condition compressor short technical problem in working life.
For solving the problems of the technologies described above; The technological scheme of the utility model is: WP7 bus engine air-conditioning carries driving mechanism; Comprise the bent axle duplex belt pulley that is arranged at motor body one end, the top of said bent axle duplex belt pulley is provided with the water pump driving wheel, is installed with air condition compressor on the motor body of said water pump driving wheel one side; Said air condition compressor connects compressor pulley, and said compressor pulley and bent axle duplex belt pulley are in transmission connection through first driving belt.
As a kind of improvement, be provided with first idle pulley between said compressor pulley and the bent axle duplex belt pulley.
As further improvement, be provided with first expansion tightening wheel between said compressor pulley and the bent axle duplex belt pulley, said first expansion tightening wheel is relative with the first idle pulley position.
Improve as another kind; A relative side with air condition compressor is installed with first generator and second generator on the said motor body; Said second generator is positioned at the top of first generator; Said first generator connects first generator drive wheel, and said second generator connects second generator drive wheel, and described bent axle duplex belt pulley, water pump driving wheel, second generator drive wheel and first generator drive wheel are in transmission connection through second driving belt successively.
As further improvement, be provided with second idle pulley between said first generator drive wheel and second generator drive wheel, be provided with the 3rd idle pulley between the said water pump driving wheel and second generator drive wheel.
As further improvement, be provided with second expansion tightening wheel between the said bent axle duplex belt pulley and first generator drive wheel.
As further improvement, said first driving belt and second driving belt are poly Vbelt.
After having adopted technique scheme; The beneficial effect of the utility model is: because air condition compressor is installed on the motor body; Make air condition compressor consistent, adopt the first driving belt transmission, can effectively reduce air condition compressor impact and noise etc. with engine vibration; Because air condition compressor is installed on the motor body, has reduced by one vibrations point on the car load chassis, added and the cushioning effect of engine suspension soft pad can effectively reduce the car load vibration and noise again, improved the travelling comfort of car load, satisfied the demand of high-end customer; Air condition compressor is installed in makes the front end train compact more on the motor, double-generator structure more convenient to use improves the generated energy of car load.
Owing to designed two independent generators; And drive by bent axle duplex belt pulley, realized that two generators are synchronous, therefore can be connected into the car load circuit simultaneously; Defectives such as the generated energy of avoiding existing in the car load double circuit structure can not be complementary, the generator utilization ratio is low; Improve the generator utilization ratio, can appropriateness reduce the rated power of generator, thereby improve the car load circuit reliability and reduce cost; Simultaneously, compare with traditional air-conditioning generator train, double-generator structure train is arranged compact; Can save air-conditioning generator train; Reducing rate of fault, also is motor air-conditioning carrying structure space for the creativity, can improve air conditioner compressed engine efficiency; Reduce because the belt sliding wear phenomenon that air condition compressor and motor relative vibration cause, with raising car load travelling comfort and reliability.
Owing to designed first idle pulley, second idle pulley and the 3rd idle pulley,, avoided occurring efficiency variance and skidding and occur for the band transmission provides the belt contact that meets the operating conditions demand.
Owing to designed first expansion tightening wheel and second expansion tightening wheel, for whole train provides vibration damping and tensioner effect, for the train proper functioning has been created good condition.
Because driving belt is chosen as poly Vbelt, the area of contact and the frictional force of poly Vbelt and belt wheel are bigger, and load is along the distribution uniform of bandwidth, thereby transmission capacity is bigger; Light, flexible good, rational in infrastructure because the poly Vbelt body is thin, so working stress is little, can on less belt wheel, work; Simultaneously poly Vbelt have also that vibrations is little, rapid heat dissipation, running steadily, use that elongation is little, velocity ratio big and characteristics such as limit line speed height, thereby the life-span is longer.
