Rear drive vehicle power chain assembly method

Abstract

The invention relates to the field of rear-drive vehicle power systems, in particular to a power chain assembly method. A method for assembling the power chain of a rear-drive vehicle. The dynamic vibration absorber is fixedly connected with the transmission shaft to form a transmission shaft assembly. The dynamic balance test is carried out on the transmission shaft assembly and the input mechanism of the rear drive axle respectively, and the transmission shaft assembly and the transmission shaft assembly are marked. The position points of the respective unbalances left after the counterweight on the balanced end surfaces where the input mechanisms of the rear drive axle are connected to each other, and finally the input mechanism of the rear drive axle is fixedly connected with the transmission shaft assembly, and the position of the unbalance between the two is fixed when connecting. Point as far away as possible. In the present invention, firstly, the transmission shaft is fixedly connected with the dynamic vibration absorber, and then the dynamic balance is found to make the light point of the input mechanism of the rear drive axle as close as possible to the key point of the transmission shaft assembly, so that the remaining unbalance of the final power chain can reach The minimum, thereby reducing the vibration and noise caused by the transmission system during the driving of the vehicle, and improving the service life of the transmission system.

Description

technical field [0001] The invention relates to the field of rear-drive vehicle power systems, in particular to a power chain assembly method. Background technique [0002] The current transmission system structure such as figure 1 Shown: The related components include: transmission shaft 1, dynamic vibration absorber 2 and rear drive axle input mechanism 3; dynamic vibration absorber 2 is used to solve the resonance problem of the transmission system caused by the torsional vibration of the powertrain of the rear-drive model, so as to realize Buffering and vibration absorption between the transmission shaft 1 and the rear drive axle 3; the existing assembly method is to assemble the three into one, because the drive shaft 1, the dynamic vibration absorber 2 and the rear drive axle input mechanism 3 are dynamic After balancing, there will still be residual unbalance. In addition, there is a gap between the matching shaft and the hole during assembly, and the on-site assembl...

[0002] The current transmission system structure such as figure 1 Shown: The related components include: transmission shaft 1, dynamic vibration absorber 2 and rear drive axle input mechanism 3; dynamic vibration absorber 2 is used to solve the resonance problem of the transmission system caused by the torsional vibration of the powertrain of the rear-drive model, so as to realize Buffering and vibration absorption between the transmission shaft 1 and the rear drive axle 3; the existing assembly method is to assemble the three into one, because the drive shaft 1, the dynamic vibration absorber 2 and the rear drive axle input mechanism 3 are dynamic After balancing, there will still be residual unbalance. In addition, there is a gap between the matching shaft and the hole during assembly, and the on-site assembly bolts need the three mounting holes to be coaxial, so the operation is very difficult, and the transmission chain of the rear-drive model itself is long. , which will lead to the uncertainty of the remaining unbalanced amount and direction of the drive train; the remaining unbalanced amount will cause abnormal noise when the vehicle is running, which not only affects the driving comfort, but also shortens the maintenance cycle of the vehicle and improves usage cost
