Above-mentioned multiplying wheel can be made up of doubly-linked driving gear and the driven gear that is connected on the output shaft, and wherein the more driving gear of the number of teeth is meshed with driven gear.The duplex driving gear can be contained on the axle of driving gear by two needle bearings, can be provided with a spacer between the two bearings.This can by connect with a through hole flush fit embedding of power takeoff housing and on the stop screw mode is arranged, reach it and be fixed on purpose in the power takeoff housing.For the oil seepage in the anti-housing here, can on this two ends, have groove and form the shaft shoulder, embedding connects a sealing O type circle that protrudes slightly on the shaft shoulder.Output shaft then can be supported by the radial ball bearing that is connected with the power takeoff housing.Be provided with U type support on the housing of power takeoff, two journal stirrups of refrigerating compressor can be attached thereto by bearing pin, and other two ears then are connected on the T type tensioner arm in the belt tension mechanism by hexagonal bar iron.
The utility model drives refrigerating compressor work owing to having adopted on change-speed box with the power takeoff outputting power, and refrigerating compressor is directly installed on the power takeoff, so compare with present air-conditioner vehicle refrigeration modes, have simple in structure, over-speed gear ratio is big, driving efficiency is high, noise is little, refrigerating capacity is big, install to adjust and easy to maintenance, safe and reliable, do not influence advantages such as vehicle performance and car load layout.The utility model makes things convenient for the layout of automotive air-conditioning system especially, can satisfy the supporting needs of various air conditioning for automobiless.
The utility model is described in further detail below in conjunction with accompanying drawing:
Figure l is the utility model structural representation;
Fig. 2 is the birds-eye view of Fig. 1;
Fig. 3 is A one an A section rotation diagram among the figure l.
The described power takeoff of the utility model is left side or the right side that is contained in change-speed box, and refrigerating compressor is contained on the housing of power takeoff.Structure of the present utility model as shown in drawings.
As scheme l, Fig. 2, shown in Figure 3, and power takeoff links to each other with case of transmission 9, and it is made up of a pair of multiplying wheel in housing 8 and this housing, output shaft 32 and the belt pulley 7 and the belt tension mechanism that are contained on this axle head and outside housing 8.On driving gear 12 in the multiplying wheel and the transmission countershaft or reverse gear on gear 11 engagements.Refrigerating compressor 1 is contained on the housing 8, and its belt pulley (draw) is linked to each other with belt pulley 7 by cone belt 16, and overall ratio (being the driving engine output speed and the ratio of power takeoff output speed) is 1～0.80.
As shown in Figure 3, above-mentioned multiplying wheel is made up of duplex driving gear 10,12 and the flower wheel 34 that is installed on the output shaft 32, and gear 10,34 is meshed.The duplex driving gear is to be contained on the axle 28 by two needle bearings 25, is provided with a spacer 26 between the two bearings.Axle 28 tight embeddings be connected in the through hole of housing 8 and on a stop screw 23 and two thrust washers 27 are arranged, each embedding connects one and seals O type circle 24 on the shaft shoulder at these two ends, this circle is made with rubber.Output shaft 32 is supported by the radial ball bearing 21 that is connected with housing 8, back radial ball bearing 33.
As shown in Figure 1 and Figure 2, the housing 8 of power takeoff is provided with U type support 14, and two journal stirrups of refrigerating compressor 1 are attached thereto by bearing pin 15, and other two journal stirrups are connected on the T type tensioner arm 3 in the belt tension mechanism by hexagonal bar iron 4.Belt tension mechanism adjusts screw mandrel 5 by T type tensioner arm 3, L type and forms, and the former is installed on the latter by two heavy series hexagon nuts 2, and latter lower end is fixed on the housing 8 by heavy series hexagon nut 6.Power takeoff is connected with case of transmission 9, is by 6 on the force taking window of speed variator mouth or several thru-bolts 13 and nut and two or several locating dowel pins both to be linked together.
