Abstract
The utility model relates to a new traction coupling device for a matched trailer using a walking tractor as a traction host machine. The structure of the utility model is that the exterior of a traction coupling shaft 10 is sheathed with a traction sleeve 11, an adjusting spacer 12, a limit sheath 13 and a fixed part to fix a relative position; the traction sleeve 11 is welded on or is fixedly connected to the upper surface of a traction draw rod 4 of a trailer through a U-shaped bolt; the traction coupling shaft 10 adopts a forged part or a cast steel part, and the front end is provided with a hole forming matching connection with a traction frame 8 and a traction plug 7 on the walking tractor. The entire device has simple structure, good manufacturability, low cost, good integral reliability, small structural quality and convenient operation.
Description
When the utility model is applicable to and makes traction engine with walker tractor, a kind of tow attachment device that supporting trailer is used.
The tow attachment device that trailer existing and walking tractor matching adopts, as shown in Figure 1.Mainly by drawing latch sleeve 6, gusset piece 5, drawing the tow attachment assembly set that sleeve 3 is formed, hitch head 1 and stop collar 2 are formed.The line of centers of the line of centers of its hitch head 1 and the traction drawbar 4 on the trailer is same axis, and its not enough place is a tow attachment assembling unit structure complexity, and intensity is low, manufacturability is poor, the manufacturing cost height.
The purpose of this utility model is to overcome above-mentioned deficiency, under the prerequisite that satisfies the existing apparatus function, provides a kind of simple in structure, good manufacturability, the trailer of low cost of manufacture tow attachment device.
The utility model is by tow attachment axle 10, traction sleeve 11, stop collar 13 and be connected and fixed part and form, it is characterized in that drawing sleeve 11 and is fixedly connected on the upper surface that draws drawbar 4.And both adopt welding or U-bolt captive joint.Tow attachment axle 10 adopts forging or steel casting, and at its front end processing one traction pin hole 9.Hole 9 is vertical with axle 10 line of centerss.
This novel trailer is made simple of the tow attachment device, cost is low, and overall reliability is good, and architecture quality is little.
Further specify below in conjunction with accompanying drawing.
Fig. 1 has the tow attachment device with the walking tractor matching trailer now
Fig. 2 the utility model constructional drawing.
See that a kind of tow attachment device that adopts with workers and peasants-12 type walking tractor matching trailer of Fig. 2 is constructed as follows: suit traction casing tube 11, bearing cap shim 12 and stop collar 13 outside tow attachment axle 10, with nut packing ring and nut 14,15,16 relative position of tow attachment axle 10 is fixed, will be drawn the upper surface that sleeve 11 usefulness welding manners are fixed in traction drawbar 4 again.Tow attachment axle 10 adopts forging, and at its front end processing one traction pin hole 9, and pin hole 9 is vertical with tow attachment axle 10 line of centerss.Traction frame 8 on the walker tractor adopts free-running fit to be connected with traction latch 7 with the pin hole 9 of tow attachment axle 10 front ends.
