Abstract
The utility model relates to a traction coupling device for trailers. A traction head is connected in a plugging manner with an attaching frame through a traction pin. A tractor can rotate oppositely to a traction shaft. A traction frame is connected with a fixed seat on the tractor through a lateral pin shaft to rotate. The utility model solves the problem that one traction coupling device simultaneously has three revolving freedom degrees. The traction coupling device is applicable to connecting the frame type traction structure of various car models with trailers.
Description
A kind of trailer towing adaptor union belongs to the connecting device of power actuated vehicle and trailer.
The most of frame traction bindiny mechanism that adopts of existing trac., this form can only satisfy two revolutions of Mz, My degree of freedom.Traction connector damages easily.Articulate at power actuated vehicle and trailer and to travel, all can influence the normal operation of vehicle owing to jolting of producing of Uneven road and the relative tilt between the two, and the traction connector between two cars also can be subjected to very big torsion, impulsive force and wearing and tearing etc., also traffic accident can take place when serious.Up to the present, also do not appear at and solve the trailer towing adaptor union that three degree of freedom is Mz, My, Mx on the traction connector simultaneously, be not resolved yet always for the problem that articulates of the towing point of different automobile types, differing heights.
The utility model is exactly to provide a kind of towing point applicable to multiple vehicle, various height to articulate at above-mentioned the deficiencies in the prior art, and has the trailer towing adaptor union of three revolution degree of freedom simultaneously.
The purpose of this utility model is achieved through the following technical solutions.Drawing head is connected with the connecting frame of power actuated vehicle by towing pin, and the axis of traction that has drawing head passes the axle sleeve at tractor two ends, and tractor can rotate relative to axis of traction.Also be provided with a permanent seat with holes on tractor, the drawbar frame of trailer joins by cotter axle and permanent seat.
Drawing of the present utility model is described as follows:
Accompanying drawing is a structural representation of the present utility model.
In the accompanying drawing: 1. drawing head.2. towing pin 3. connecting frames 4. axis of traction 5. tractors 6. axle sleeves 7. permanent seats 8. drawbar frames 9. cotter axles 10. nuts.
Now reach embodiment in conjunction with the accompanying drawings the utility model is made a detailed description.
Integral structure of the present utility model has been shown in the accompanying drawing.Drawing head 1 is plugged in the connecting frame 3 of power actuated vehicle by towing pin 2.Both ends at tractor 5 are provided with axle sleeve 6 respectively, and the axis of traction 4 that has drawing head 1 is through axle sleeve 6, and it is fastening by nut 10 that axis of traction 4 exceeds 5 part.Be provided with a permanent seat 7 with holes on tractor 5, the termination of drawbar frame 8 joins by cotter axle 9 and permanent seat 7 with holes.
When trailer did not articulate with power actuated vehicle, traction connector was connected the termination of trailer towing frame by cotter axle.When needs articulate, only need and to put into connecting frame with the drawing head of trailer towing frame bonded assembly traction connector, and run through connecting frame and drawing head with towing pin and can realize being connected of power actuated vehicle and trailer.Since can relatively independent rotation on three different directions at tractor and axis of traction, the axis of traction that has drawing head and towing pin, drawbar frame and permanent seat on the trailer towing adaptor union, the revolution degree of freedom of three different directions just produced.
But the utility model has been owing to adopted in Mz, My, three directions of Mx structure of independent rotation all, solved on same device, have Mz, My simultaneously, the problems of three revolutions of My degree of freedom.Can rotate around cotter axle (Mx) with permanent seat bonded assembly trailer towing frame, can carry out self to the power actuated vehicle that occurs because of the Uneven road situation different and regulate with the trailer height.And tractor is around the rotation of axis of traction (My), but adaline motor vehicle and different relatively the reversing of causing of trailer because of the road surface degree of dip.Because of power actuated vehicle and trailer are then solved by drawing head and relatively rotating of towing pin (Mz) in the left and right swing of turning or interim adjustment direction in service causes.This traction connector has satisfied the operating needs that various frame tractions articulate.Also solved the problem that articulates of various trac. differing heights towing points, and can be with heavy duty, unloaded and change because of the Uneven road variation that causes towing point of jolting.
Claims (1)
1, a kind of trailer towing adaptor union, drawing head is connected with the connecting frame of power actuated vehicle by towing pin, the axis of traction that it is characterized in that having drawing head runs through the axle sleeve at tractor two ends, tractor can rotate relative to axis of traction, also be provided with permanent seat on tractor, the trailer towing frame links to each other with permanent seat by cotter axle.
