4 Line 8 Axle Removable Gooseneck Trailer
Typical removable gooseneck trailer
The gooseneck of the removable gooseneck trailer usually consists of four parts: the traction system, the force transmission system, the alignment adjustment system and the locking system. The locking methods of the detachable gooseneck and the front end of the semi-trailer include traction saddle locking, pin locking and cam locking, etc.; the horizontal alignment of the gooseneck and the front end of the removable gooseneck trailer includes pin alignment, guide groove alignment, and vertical alignment with mechanical adjustment, Winch adjustment, air pressure adjustment and hydraulic adjustment. Detachable gooseneck and removable gooseneck trailer. The front-end load transfer methods mainly include hook, orifice and orange. There are two locking control methods: manual control and pneumatic control.
Mechanically removable gooseneck
The mechanically removable gooseneck is a whole, and there is no relative movement in the fixed connection between the various parts.
The gooseneck itself does not have a height adjustment function, and when it is connected with a removable gooseneck trailer, it relies on a modified tractor frame to provide the required slope adjustment. The disassembly and assembly process of the gooseneck of the mechanically detachable gooseneck low flatbed semi-trailer often requires moving the tractor back and forth several times to complete, so it is not suitable for short-distance transportation.
The principle of mechanical detachable gooseneck structure The mechanical detachable gooseneck frame is similar to the frame of the semi-trailer body. All are symmetrical with respect to the longitudinal vertical center plane. And indirectly contact with the ground (supported by the ground). The front end of the gooseneck is connected to the towing saddle of the tractor through the towing pin. The relationship between the tractor and the gooseneck is that the tractor can rotate around a vertical axis relative to the gooseneck. When detached from the traction saddle. The tractor can drive off the removable gooseneck trailer. The part where the tractor and the traction saddle meet (or become part of the traction saddle) are often made into inclined planes 1 and 2 with different inclination angles that are inclined backward and downward with respect to the ground.
The forward and downward tilting plane a at the front end of the semi-trailer body is aligned with the backward and upward tilting plane b at the lower end of the gooseneck. This structure is clothed after the gooseneck is in direct contact with the removable gooseneck trailer. A continuous contact plane can be provided between the two so that the two can be further matched and connected. A phase hole is opened at the rear end of the front end of the removable gooseneck trailer body adjacent to the inclined plane a. Its size is just enough to allow the protruding rod at the rear end of the gooseneck to be inserted (as shown in Figure 15-19). The protruding rod not only includes a supporting neck. It also includes a freely extending raised portion. Its shape is L-shaped. The protruding rod can be in adjacent contact with the orthogonally erected limit stop on the semitrailer body.
The position of the protrusion may be defined by an orthogonal plug with a beveled front end. The compressed spring between the pin head and the fixed connecting plate serves to restrict the protrusion from moving along the longitudinal direction of the removable gooseneck trailer and prevent the gooseneck from detaching from the semi-trailer. The tail of the bolt is hinged to the connecting rod, and then to the horizontal rocker through the connecting rod. The horizontal rocker is then hinged with the vertical rocker. Therefore, you can manually pull the handle at right angles to the vertical rocker by manually (through the circular notch on the side of the car) to retract the latch to remove the obstacles to the longitudinal movement of the protrusion.
When the handle is rotated counterclockwise, the latch will be released under the pull of the horizontal rocker to move away from the center. The protrusion at the end of the protruding rod moves backward toward the limit stop, and is retracted by pressing the inclined surface of the latch, and finally contacts and presses the limit stop. After that, the plug springs back under the action of the compression spring and prevents the protrusion from moving out. In this way, the gooseneck and the semi-trailer are doored together to form a whole, which can be moved back and forth and laterally. In the area of ??the latch position, the gooseneck and semi-trailer usually need to rotate around an orthogonal horizontal axis. For this reason, the inclined plane a is combined with the relatively flat part of the upper plane of the semi-trailer close to the position of the latch mechanism, and the round end is designed on the gooseneck so that the gooseneck can swing on the flat upper surface of the semi-trailer. The size of the bolt and the slot hole meets the requirement that the bolt can rotate freely in the drawing hole.
When the gooseneck and the removable gooseneck trailer are connected together by the inclined plane and the inclined plane h, the weight of the semi-trailer will be transferred. It is borne by the gooseneck through a special connecting mechanism. There are stationary pins on each side of the forked gooseneck! Its rear end is tapered and fixed to the gooseneck; its front end extends horizontally in the forward direction, and is connected to the lower part of the gooseneck arch structure by a steel belt by welding.
