The sidepiece of described towing pin offers deep-slotted chip breaker, and the middle part of described towing plate offers the through hole corresponding with deep-slotted chip breaker, and through hole is connected with deep-slotted chip breaker by binding bolt.
Described towing plate is inverted U structure, comprise arc-shaped transition section and a symmetrically arranged side plate, No. two side plates, the bottom of a described side plate, No. two side plates is all connected with base, the top of a side plate, No. two side plates is connected with the two ends of arc-shaped transition section respectively, the middle part correspondence of a side plate, No. two side plates offers through hole, the inner side of described arc-shaped transition section and towing pin free-running fit.
On described base, offer the bolt hole being fixedly connected with vehicle frame.
Compared with prior art, the beneficial effects of the utility model are:
1, in a kind of novel traction seat assembly of the utility model, the sidepiece of towing pin offers deep-slotted chip breaker, the middle part of towing plate offers the through hole corresponding with deep-slotted chip breaker, and through hole is connected with deep-slotted chip breaker by binding bolt, it is spacing to be that towing pin passes through binding bolt, fixed form is more reliable, effectively avoid the relative motion of itself and traction seat, thereby prevented the corrosion of towing pin, traction seat.Therefore, the utility model has effectively prevented the corrosion of towing pin, traction seat.
2, a kind of novel traction seat assembly of the utility model, without erection insurance pin assembly, needn't be reserved the installation site of safety plug, and then its length can suitably shorten, and not only cost is lower, and can not cause the loss of towing pin.Therefore, the utility model not only cost is lower, and can not cause the loss of towing pin.
