Description
Technical field
The present invention relates to trailer superimposed trailer saddle technical field, more particularly, relate to a kind of lock pin steering unit used on saddle.
Background technology
Along with the continuous growth of trade of goods activity, transit industry is also developed thereupon, and the most outstanding with the development of mass freight transport and Container Transport, thus facilitates the development of trailer superimposed trailer relevant industries.Saddle is the special purpose parts of various tractor truck, and it is arranged on the vehicle frame of tractor truck, the coupling realizing tractor truck and superimposed trailer be separated.The use of saddle realizes primarily of steering unit, the effect of saddle joystick structure is the connection that utilizes handlebar to carry out lock bolt and towing pin with lever form and be separated, saddle joystick needs to be connected with lock bolt, existing saddle joystick when mounted, need to inject in saddle panel from the hollow hole of saddle crossbeam, then insert from the perforate saddle panel with bolt, through latch hole, joystick connecting bore, then connect fastening nuts.Saddle also needs the vented cap packing on panel to put down after completing assembling, enter to prevent the foreign matters such as dust.Therefore, current saddle joystick also exists all very inconvenient shortcoming of installation, maintenance.
Summary of the invention
The deficiency that the object of the invention exists to overcome above-mentioned prior art, provides a kind of installation, maintenance dismounting lock pin steering unit all very easily, thus enhances productivity.
The technical solution used in the present invention is: lock pin steering unit, be arranged on the panel bottom surface of saddle, comprise joystick, lock bolt, also comprise latch pin, Anti-rotary block, jam nut, described latch pin is provided with flat side and threaded portion, and described joystick is provided with mounting hole and opening, latch pin is through lock bolt, joystick is inserted from the flat square set of opening part by latch pin, and the flat side of latch pin also installs Anti-rotary block, and Anti-rotary block is pressed on joystick, the anti-rotation claw of Anti-rotary block extends to the opening part of joystick, and the end of latch pin is threaded with jam nut.
Described lock bolt is arranged in the lock bar slot bottom saddle panel.
Described joystick inserts in lock bar slot from the hollow hole of saddle crossbeam and is connected with lock bolt.
Spring washer is provided with between jam nut and Anti-rotary block.
Packing ring is provided with between joystick and lock bolt.
Compared with prior art, lock pin steering unit of the present invention, be open pore by the connecting bore structure design of joystick, when mounted without the need to filling bolt through the perforate on panel, realized the assembling of latch pin and joystick dexterously by the flat square structure of latch pin, and join with Anti-rotary block, lock bolt and joystick are linked together by latch pin securely.The present invention, by scientific and reasonable structure design, solves a difficult problem for existing saddle joystick assembling difficulty, send the working strength alleviating workman, enhance productivity.
