Description
Technical field
The utility model relates to a kind of fitting line dolly, particularly relates to a kind of fitting line dolly for automobile axle of improvement.
Background technology
Back axle, just refers to the rear drive shaft component part that vehicle power transmits.It is made up of two half-bridges, can implement half-bridge differential motion.Meanwhile, it is also used to support wheel and the device being connected rear wheel.If the vehicle that propons drives, so back axle is only just follow-up bridge, only plays the effect of carrying.If propons is not drive axle, so back axle is exactly drive axle, at this time also plays to drive and slow down except carrying effect to also have the effect of differential, if four wheel drive, generally before back axle, be also furnished with a part-time case.Back axle is divided into overall bridge and half-bridge.Dependent suspension joined by overall bridge, and as plate spring suspension brackets, half-bridge joins independent suspension, as McPherson strut.
Automobile axle just refers to that root bridge after automobile.If propons is not drive axle, so back axle is exactly drive axle, at this time also plays to drive and slow down except carrying effect to also have the effect of differential, if four wheel drive, generally before back axle, be also furnished with a part-time case.Propons back axle just refers to the part of front and back wheel axle, and propons comprises shock-proof spring, deflector, balance shaft etc., and back axle also comprises axle drive shaft, transmission gear etc.Multiaxis truck back also divides driving back axle and without driving back axle, do not have transmission shaft to connect exactly without driving back axle, not belonging to the part of drive wheel, is generally that heavily card and the tractor of more than 3 axles just has.
Different according to the suspension of bridge, be divided into integral type and breakaway-element.Overall bridge joins dependent suspension, as plate spring suspension brackets.Breakaway-element joins independent suspension, as McPherson strut.Large bulge as back axle center just has when back axle is drive axle, because reducing gear and box of tricks will be put in the inside, so will there be a large bulge, back axle is that the general of follow-up bridge does not all have.
On current rear axle assembling line, the form of automobile axle assembling is: adopt directly will or back axle buttress be placed on travelling car, then travelling car is pushed into work-yard and implements to install.But, usually there will be put parts not only inconvenient adjusting angle but also there is the danger easily toppled over when assembling, causing many installation inconvenient.If directly purchase this type of Assembling bogie from the market, both impracticable, price is also very expensive.And mainly there is following shortcoming: the automobile axle that can only be suitable for a kind of model, can not automatically regulate its stability, efficiency of assembling is low, and safety of operation is low, and during operation, labor strength is high, wastes time and energy; Location inaccuracy, causes assembly error in fitting process; Repeatedly locate and cause benchmark to change, having a strong impact on assembly quality.
