Thereby the invented modules can be connected casually with each other anytime, anywhere, and combined into a "changeable" module clutch type semi-trailer. The core of the invention is the "variable" purpose: a variable semi-trailer can transport any cargo and drive on any road.

The specific structure of each module device is described in detail below:

Further; the gooseneck module device specifically includes 1. concave-convex connection gooseneck; 2. double-pin connection gooseneck;

As shown in Figures 2-9, the concave-convex connection gooseneck specifically includes a gooseneck lock block 101, a gooseneck body 102, a gooseneck groove 103, a saddle 104, and a hydraulic system device 105, wherein:

The front portion of the gooseneck body 102 is provided with a gooseneck protruding shaft 106, and both sides of the tail of the gooseneck body 102 are provided with loading surface connection ports 107; There is a connecting lock pin 108; the gooseneck body 102 is embedded in the gooseneck groove 103 through the gooseneck protruding shaft 106 at the front to form a rotational fit, and the gooseneck body 102 is also connected through the loading surface at the tail The port 107 and the connecting lock pin 108 are mated and connected with the loading surface module device 200 of the vehicle body;

The bottom of the gooseneck groove 103 is also fixedly connected with a traction pin 109; the traction pin 109 at the bottom of the gooseneck groove 103 forms a pin-hole fit connection with the mounting hole on the saddle 104;

The gooseneck lock block 101 is fixedly connected to the gooseneck groove 103, and the gooseneck lock block 101 is used to define the gooseneck protruding shaft 106 at the front of the gooseneck body 102 in the gooseneck recess. Up and down movement in the vertical direction in the groove 103.

It should be noted that the gooseneck module device 100 mainly consists of a gooseneck lock block 101, a gooseneck body 102 (including a gooseneck protruding shaft 106 at the front and a loading surface connection port 107 at the tail end, etc.), a gooseneck groove 103 and Structural components such as saddle 104 and hydraulic system device 105:

This semi-cylindrical gooseneck protruding shaft 106 (and gooseneck body) is connected to the body of the semi-trailer, while the gooseneck groove 103 in the shape of a semicircular groove is realized by the traction pin 109 and the saddle 104 on the headstock. Fixed connection; in this way, when the gooseneck protruding shaft 106 is embedded in the gooseneck groove 103 to form a mating connection, the vehicle body and the front can be connected and separated; the gooseneck protruding shaft connected to the vehicle body (loading surface module device) After 106 is clamped and embedded in the gooseneck groove 103, due to the effect of the gravity of the vehicle body itself, the gooseneck protruding shaft is firmly clamped in the gooseneck groove, so that the two will not be separated (at the same time, the vehicle body can be connected to the front of the vehicle. ); In addition, when the gooseneck protruding shaft 106 breaks away from the gooseneck groove 103, the two can be separated (while the vehicle body can be separated from the front). In this way, the novel gooseneck device also has the function of easy disassembly and assembly.

The gooseneck body 102 is embedded in the gooseneck groove 103 through the gooseneck protruding shaft 106 at the front to form a rotational fit, and the gooseneck body 102 is connected to the vehicle body through the loading surface connection port 107 and the connecting lock pin 108 at the rear. The loading surface module device 200 of the semi-trailer is matched and connected; when the semi-trailer is driving on a bumpy road, the vehicle body and the loading surface module device will bump and vibrate, causing the vehicle body to shake from side to side; obviously, the rigid connection (that is, the rigid transmission) of the traditional semi-trailer will It will cause the vibration of the semi-trailer body to be transmitted to the front of the tractor, which has a great impact on the safe driving of the driver;

However, even if the body of the gooseneck device of the present invention shakes, it will only cause the protruding shaft of the gooseneck to rotate a certain amount in the groove of the gooseneck. The connection method between the shaft and the gooseneck groove can protect the vehicle frame on heavy-duty driving on uneven roads; when the tires behind the vehicle body roll over the uneven road surface, vibrations and bumps will basically not be transmitted to the front The front part of the car will not cause the vibration of the front of the car, providing the driver with a good driving environment. At the same time, the inner parts of the front of the car are relatively stable, which can enhance the service life of the inner parts of the front of the car and improve the stability of the whole vehicle. The advantages of the above-mentioned concave-convex connection gooseneck are as follows: shockproof: the clamping mode of the convex shaft of the gooseneck and the groove of the gooseneck (that is, the concave-convex connection mode) can prevent the front of the car from being affected by the swing of the tail; No skidding; anti-rollover: the tail collapsed semi-trailer rollover does not affect the tractor head;

Further, in the specific structure of the gooseneck body:

Obviously, the above-mentioned gooseneck protruding shafts and gooseneck grooves have special shapes and structures, so that they can form a rotatable snap fit; that is, the gooseneck protruding shafts at the front of the gooseneck body are specifically semi-cylindrical convex Shaft; the gooseneck groove is specifically arc-shaped; and the inner contour of the gooseneck groove is adapted to the arc surface of the outer contour of the gooseneck convex shaft, so as to ensure a tight and stable fit between the two. At the same time, an appropriate amount of rotation can be carried out (that is, the semicircular surfaces are in contact with each other, which can make the rotation more stable and gentle), and play the role of rotation shock absorption.

Further, in the specific structure of the gooseneck lock block:

There are specifically two gooseneck lock blocks 101, which are respectively arranged on the left and right sides of the gooseneck groove 103; each of the gooseneck lock blocks 101 specifically includes a lock block 110 and runs through the The two locking screws 111 of the locking block; the bottom of the locking screw 111 is connected with the gooseneck groove 103, and the top of the locking screw 111 is connected with the locking block 110; and the locking block The inner wall of 110 is a concave arc surface; the concave arc surface of the locking block 110 is adapted to the convex axis arc surface of the gooseneck protruding shaft 106 .

The working surface cannot be adjusted to cause loss of supply;

The defects and deficiencies caused by the current situation are as follows: 1. When the new driver or the road conditions are not familiar, when entering a curve or meeting with the opposite vehicle, the weight of the cargo loaded is not equal to the road grade, resulting in the collapse of the rear wheel of the semi-trailer together with the front The driver rolled over the concave part of the road, causing life safety accidents. 2. The driving wheel is inclined to bend, the center of gravity is not uniform, and the force is uneven, so the dangerous curve is suspended and stopped. Generally, it takes ten minutes, one hour or even longer before the driver solves the problem. Leaving potential safety hazards and increasing various direct hidden costs. 3. The torsion and vibration of the convex and concave roads cause loosening and fracture of the joints such as the tractor head beam and saddle. Vibration vibration increases driver fatigue and causes accident hazards. 4. When the saddle of the tractor is cracked and the lock pin is broken and some minor problems occur, the front and the semi-trailer cannot be separated and joined when necessary and due to many steps and too complicated. Also cause cost increase because of saddle life-span about two years etc., allow operator's efficiency low.

Further, the load-bearing module device is mainly divided into four types of load-bearing module devices: a central load-bearing device, a three-bearing load-bearing device, a single-axis auxiliary load-bearing device, and a double-axis auxiliary load-bearing device. As shown in Figures 17-21, the load-bearing module device (that is, the load-bearing module device 300) specifically includes two left and right side beams 301, a middle beam 302 arranged between the two side beams 301, a suspension system 303 and Wheel set device 304 and lifting mechanism;

The connection relationship, positional relationship, specific structure and structural layout among the above load-bearing device structures are as follows:

Wherein, the left and right two side beams 301 and the middle beam 302 are arranged in parallel vertically, and are fixedly connected between the two side beams 301, the middle beam 302 and a plurality of cross beams 305; the width of the middle beam 302 is slightly larger than the width of the two side beams 301; and the lifting mechanism is arranged between the middle beam and the suspension system;

The body is its main structural part, and the load-bearing beam of the body mainly plays a load-bearing role. The load-bearing beam is mainly divided into three parts, namely the left side beam, the right side beam and the middle beam.
