Abstract
The utility model relates to a device for controlling turn of the trailing frame of a trailer, which belongs to the ground vehicle equipment. The stationary traction pins of the existing trailers are replaced with force landscape moving traction pins. The lateral movement of traction pins causes the deflection of the trailer traction frame that is connected with the traction pins so that trailing cars, pulling and hanging the entire car deflects flexibly and conveniently and cars run on the road that is comparatively narrow. In narrow fields the direction and location of the entire car is adjustified through backing and ahead running. The utility model has the advantages of simple structure, operational safety, relatively low costs, and so on, and is widely used for the existing drag trailers.
Description
The utility model belongs to land vehicle equipment.
When transporting,, generally take the method for pulling in order to increase transportation volume with vehicle.The self-propelled vehicle that the front has power is called trailer, and the trailed car in back is called trailer.The tail end of trailer is provided with towing pin, is connected with the drawbar frame of trailer front end.The towing pin device is fixed on the trailer longitudinal axis symmetrical plane.Drag, when trailer is turned to overtake, handle the bearing circle of trailer, make the deflection of trailer towing frame with the mode of the whole trailer of deflection, thereby drive trailer deflection, the turning driving of car load is dragged, hangs in realization.Because car load is longer, during turning, the trailer of back might depart from the road surface.Under the situation particularly narrow at road, that turn radius is less (being that bend of road is bigger), car load can not one shot, needs repeatedly reversing-ahead running to pass through.In addition in narrow and small place, when adjusting the direction of car load and position, particularly when reversing enters narrow place between two vehicles, also need could realize through reversing-ahead running several times, seem very inconvenient.
The purpose of this utility model provides a kind of device of handling the deflection of trailer towing frame.Make trailer and turn to flexible to dragging, hang car load.
The utility model by trailer chassis, be connected with towing pin with trailer chassis rear end bonded assembly towing pin, an end, the other end and trailer front end bonded assembly drawbar frame etc. form, it is characterized in that, the transverse moving device of towing pin is set between trailer chassis and towing pin.This transverse moving device makes towing pin make cross motion, makes the drawbar frame deflection that is attached thereto, and turns to thereby drive drawbar frame bonded assembly trailer.
The utility model is simple in structure, cost is low, this device is set after, drag, hang car load and turn to flexibly, be convenient at narrow road driving; Drag, hang the direction and the position of car load in narrow and small place adjustment.
Below by embodiment the utility model is described in further detail.
Accompanying drawing 1 is a birds-eye view of the present utility model
Accompanying drawing 2 is used another technical scheme of towing pin transverse moving device of the utility model.
Referring to Fig. 1, trailer chassis (1) rear end is provided with the transverse moving device of towing pin (2).This device has a double acting hydraulic actuating cylinder (3) and control setup (8) thereof, the piston rod of hydraulic actuating cylinder (3), one end is that piston is in hydraulic cylinder, it is outer and towing pin (2) one ends are hinged that the other end stretches out hydraulic cylinder, the other end of towing pin (2) connects with the drawbar frame (6) of trailer, trailer chassis (1) is provided with side travel guide rail (4), and towing pin (2) can move laterally along side travel guide rail (4).
The control setup (8) of operating hydraulically operated cylinder (3) advances piston one piston rod of hydraulic actuating cylinder (3) or retreats, and drives towing pin (2) and moves laterally along side travel guide rail (4), and its end position is A and B, makes drawbar frame (6) deflection α angle.Drawbar frame (6) one ends are connected with towing pin (2), the other end can with trailer front end direct connection; Also can be connected with the dish (5) that rotates that is installed in the trailer front portion, along with the deflection of drawbar frame (6), the dish (5) that rotates is with respect to trailer deflection, thereby makes trailer change of direction when advancing or fall back.
The transverse moving device of towing pin (2) can adopt other hydraulic pressure, compressed-air controlled, pattern electric power or pure machinery.
Figure 2 shows that the technical scheme that fluid motor-driven gear-rack drives towing pin moves along side travel guide rail (4).This transverse moving device by HM Hydraulic Motor (9), be fixed on gear (10) on the hydraulic motor output shaft, form with tooth bar (11), side travel guide rail (4), the HM Hydraulic Motor maneuver control device (8) of gear mesh, towing pin (2) is captiveed joint with tooth bar.By the forward or reverse of the operating hydraulically operated motor of maneuver control device (8) (9), thereby make gear (10) forward and backward, drive towing pin (2) that tooth bar (11) reaches and it is fixing and move laterally along side travel guide rail (4).
The transverse moving device of towing pin (2) also can by sliding nut or the band circulating steel ball nut, form with its ingear screw rod and side travel guide rail (4).When screw rod rotated, nut just moved, and moved laterally along side travel guide rail (4) thereby drive with its fixing towing pin (2).
The transverse moving device of towing pin (2) also can be to make towing pin (2) around a certain spot wobble in trailer chassis rear end.This device is formed by the bearing pin of trailer chassis (1) rear end and with bearing pin pivotally attached towing pin (2).When towing pin (2) by power when bearing pin is swung, drive and towing pin (2) bonded assembly drawbar frame (6) deflection.
More than side travel guide rail (4) in said towing pin (2) transverse moving device be linear, also can be circular arc or other suitable curve profile.
Claims (5)
1, a kind of device of handling the deflection of trailer towing frame, it by trailer chassis (1), be connected with towing pin with trailer chassis's rear end bonded assembly towing pin (2), an end, the other end and trailer front end bonded assembly drawbar frame etc. form, it is characterized in that, the transverse moving device of towing pin is set between trailer chassis (1) and towing pin (2).
2, according to the device of the said manipulation trailer towing of claim 1 frame deflection, it is characterized in that, said towing pin transverse moving device is made up of the maneuver control device (8) of hydraulic actuating cylinder (3), side travel guide rail (4), hydraulic actuating cylinder, piston rod one end of hydraulic actuating cylinder (3) is that piston is in hydraulic cylinder, it is hinged that the other end stretches out hydraulic cylinder one end outer and towing pin (2), and towing pin (2) moves along side travel guide rail (4).
3, according to the device of the said manipulation trailer towing of claim 1 frame deflection, it is characterized in that, said towing pin transverse moving device by HM Hydraulic Motor (9), be fixed on gear (10) on the hydraulic motor output shaft, tooth bar (11), side travel guide rail (4), the maneuver control device (8) of HM Hydraulic Motor and form with gear mesh, towing pin (2) is captiveed joint with tooth bar (11), moves laterally along side travel guide rail (4).
