Abstract
The invention relates to a rear traction device for a first tractor to draw a second tractor of a tractor with a one-traction-two mode. The rear traction device can make a tractor and a towed vehicle reliably coupled to achieve the safe driving and the operation of towing the towed vehicle by the tractor. The rear traction device comprises a welded base plate, a traction seat assembly and a connecting device; the welded base plate is arranged below the traction seat assembly; and the connecting device is arranged above the traction seat assembly. As the connecting device adopts a groove type composite structure and is reliably coupled with a traction seat of a molded product, the bearing surface is large; the surface of the traction seat is provided with a lube groove; the addition of lube reduces the abrasion between the surface of a seat plate and the surface of a connecting body; and the rear traction device has the advantages of simple structure, good safety, wide ranged of application, low processing cost, and the like, realizes the one-traction-two operation mode of the tractor and fills up one blank of the state.
Description
Technical field
The present invention relates to a kind of draw gear of second tractor truck of first tractor truck traction of tractor truck one drag two operation scheme, it can make tractor truck and be pulled car and reliably be coupled, and reaches the safety traffic operation that the tractor truck traction is pulled car.
Background technology
At present, the most employings of the transportation mode of tractor truck is solo running; What minority adopted is that a back of the body one mode is transported; This mode is the fastening connection of longeron that makes second tractor truck and first tractor truck through chock, steel rope and clip; There are many shortcoming and defect parts in above-mentioned transportation mode, is in particular in: 1. the solo running mode has caused the waste of the waste, the particularly energy of very big manpower and financial resources; 2. a back of the body one mode Transport Safety is unreliable, inefficiency, consumption oil.
The objective of the invention is to provide a kind of and can realize tractor truck one drag two operation scheme, thereby increase work efficiency greatly, fuel saving, good, the dependable performance of safety, the draw gear that can be recycled.
Summary of the invention
The objective of the invention is to realize like this: this draw gear comprises base plate seam, traction seat assembly and connecting device; Described base plate seam be arranged on the traction seat assembly below; Connecting device is arranged on above the traction seat assembly; Connecting device connects coupling through the towing pin on it with the traction seat assembly, and can be that axle rotates on the traction seat assembly with the towing pin.
Described connecting device comprises connected body seam, adjustment groove, end fastener, locating dowel pin and middle fastener; Wherein adjust groove is arranged on the connected body seam through locating dowel pin inside; The end fastener is arranged on the two ends of connected body seam; Middle fastener is arranged on the middle part of connected body seam, and two sides of described adjustment groove have four breach, and is connected with strengthening groove and is contained in the permanent seat through locating dowel pin.
Described connected body seam comprises connected body body, square nut, strengthening groove, towing pin, permanent seat, left Connection Block, right Connection Block and brace panel; Wherein the middle part of connected body body is welded with towing pin; Be welded with permanent seat on the plane above that; And two sides of permanent seat have four breach, and the inboard is welded with strengthening groove, and knock hole is arranged on the strengthening groove; Left and right sides Connection Block be welded in permanent seat the middle part outside and with connects the body weldering and is one, square nut be welded in permanent seat the outside two ends and same be one with connecting that body welds.
The present invention is because connecting device has adopted the grooved composite structure reliably to be coupled with molded product traction seat, so carrying surface is big, there is oilway on the traction seat surface in addition, and the filling lubricating oil has reduced the wearing and tearing of seat board surface with the connected body surface; Simple in structure, advantage such as safety is good, and is applied widely, and tooling cost is low, and realized the operation scheme of tractor truck one drag two, filled up blank of China.
