Two cant beams of described tripod assembly are rectangular tube, and counter pulley mounting bracket and fan pulley mounting bracket are stamping part.
Described tripod assembly is arranged on the gantry frame structure of underframe of coach.
After having adopted technique scheme, the present invention has following positive effect: (1) the present invention with the Design of mounting plate of the mounting bracket of fan pulley and counter pulley on the tripod assembly of same triangle rack and panel construction, make like this planeness of fan pulley and counter pulley just can well be guaranteed in the process of tripod manufacturing, assembly precision between having improved both can be good at and two belt grooves interlocks the fan belt; Only need the workman to carry out simple the adjusting during assembling and get final product, the time of assembling and later stage adjusting of having saved has been improved working efficiency, is suitable for the batch production of vehicle; Triangular structure also has good stability simultaneously, and total stability is strengthened.
(2) three of tripod of the present invention drift angle assemblies comprise stationary bushing and rubber bushing, wherein rubber bushing is directly to be vulcanized by vulcanized rubber to form between two steel parts, again with tripod on stationary bushing couple together by interference fit, so just can make the certain damping of generation between tripod and vehicle frame, can bear certain radial load.Through test, when the rubber bushing of this spline structure is 50Kg power when radial force, amount of deformation f=0.07mm, every increases of radial force 50Kg power, its amount of deformation increase 0.05mm during in 300Kg power, can not occur inefficacy when radial force yet.And the stressed situation of change of the suspending apparatus of motor is generally pressure 460Kg force deformation amount fmax=5mm, shearing force 117Kg force deformation amount fmax=8mm, as seen this kind rubber bushing motor of effectively having decayed when having guaranteed join strength passes the vibrations of coming, avoided tripod to shake too early damage because of long-term rocking, simultaneously also reduce beating of fan belt, extended the working life of fan belt.
(3) intermediate belt wheel shaft of the present invention is designed to eccentric shaft structure, counter pulley is in the first axle central point rotation like this, can also swing around the second axle central point, when engine vibration, the bent axle belt can be shaken pine when tight when affecting, because counter pulley can swing around the second axle, the power of these vibrations is dispersed to the fan belt, both stressed of fan belt and bent axle belt recovers again identical, whole vibrations are weakened, make native system have certain self-balancing ability.
(4) intermediate belt wheel assembly of the present invention comprises 2 bolts that slide in can the restraining groove on the breast wheel support, can easily adjust the position of breast wheel by adjusting screw rod, can guarantee that the fan belt is stressed identical with the bent axle belt during tightening belt like this, the belt on the both sides of tensioning has simultaneously been avoided causing one of them too early wearing and tearing because of unbalance stress.
(5) two of tripod assembly of the present invention cant beams adopt rectangular tube as the main body of structure, fan belt wheel support and intermediate belt wheel support all adopt stamping part, greatly alleviated the weight of whole support, also make its being dwindled over against area with respect to radiator, so namely reduced cost, its impact on the fan exhaust resistance has been reached minimize, the heat dissipation of fan is effectively guaranteed.
(5) tripod assembly of the present invention is arranged on the gantry frame structure of underframe, and a whole set of Fan Transmission-mechanism is thoroughly separated with wind shelling cover with water tank, avoided the vibrations of motor are delivered on water tank, has stopped the phenomenon that water tank is shaken leakage.The while wind shelling cover is bearing load not, can adopt the thinner steel plate punched of wall thickness, or makes of glass fibre reinforced plastics, can save cost like this, is conducive to batch production.
(6) overall structure of the present invention is simple, is not subjected to the restriction of engine structure, according to different motors, only needs to change different bent axle belts and gets final product, and has a extensive future.
