Technical Field

[0001] This utility model relates to the field of tractor equipment technology, specifically a mountain tractor trailer. Background Technology

[0002] Tractors are commonly used agricultural machinery, widely applied in various agricultural production and daily life. When used in mountainous operations, they are often required to tow trailers for material transport and direct towing operations. Existing modular trailers typically use a hook device installed at the rear of the tractor body to directly tow and lock the trailer, with the tractor's power driving the trailer. However, in mountainous operations, due to the relatively rugged terrain, uneven surfaces, and situations such as turns and uphill / downhill sections, uneven power can easily lead to collisions between the front and rear vehicle components, trailer fishtailing, and lateral or vertical rollovers. Furthermore, attaching a tractor-driven trailer to make the trailer and tractor a single unit is not permitted; a detachable trailer must be used for temporary transport to meet the plug-and-play towing requirements.

[0003] To achieve the above objectives, this utility model provides a mountain tractor trailer that can solve the problems mentioned in the background art. Utility Model Content

[0004] This utility model adopts the following technical solution:

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.

[0026] Please refer to the attached document carefully. Figure 1-3 The system includes a trailer beam frame 1 and a trailer body 2. The trailer beam frame 1 includes a locomotive body 101 and a drive body 104. A longitudinal movable arm 102 is provided above the end of the locomotive body 101 near the tractor engine. Two transverse support arms 103 are provided on both sides of the locomotive body 101. A longitudinal guide rail is provided on each side of the longitudinal movable arm 102.

[0027] The trailer body 2 is provided with a trailer wheel pair 203 at the bottom, and the drive rod of the trailer wheel pair 203 is connected to the engine of the tractor through the drive box 104;

[0028] A load-bearing beam 205 is connected between the trailer body 2 and the trailer beam 1. The end of the load-bearing beam 205 is movably connected to the inside of the two pin seats 110. A U-shaped stabilizing frame is fixedly provided at the bottom of the load-bearing beam 205. One end of the transverse support wall is sleeved inside the U-shaped stabilizing frame.

[0029] Please refer to this carefully. Figure 1-3 The input gear of the drive housing 104 is connected to the engine drive end of the tractor. The drive housing 104 is provided with a power take-off gear set 105 that meshes with the input gear and a drive output end 106. The drive output end 106 is connected to the front wheel pair and the rear wheel pair of the trailer beam 1 on both sides. The output end of the power take-off gear set 105 extends out to provide a trailer output end 107.

[0030] The drive input end of the trailer wheelset 203 is connected to a direct drive shaft 202, and one end of the direct drive shaft 202 is provided with a transmission sleeve 201 connected to the trailer output end 107.

[0031] The drive output terminal 106 includes a front drive output terminal and a rear drive output terminal. A mounting plate with a movable bearing connection can be provided between the front drive output terminal and the rear drive output terminal. At this time, the front drive output terminal 106 and the rear drive output terminal 106 operate independently.

[0032] Please refer to this carefully. Figure 1-3 The U-shaped stabilizer 204 has cushioning material filling both the upper and lower bottom surfaces, and the cushioning material wraps around the outside of the transverse support arm 103.

[0033] The load-bearing beam frame 205 includes a flatbed frame 207 and two drag arms 206. One end of each drag arm 206 is provided with a sleeve head 111, which is sleeved on the outside of the pin seat 110.

[0034] Please refer to this carefully. Figure 1 The transmission sleeve 201 and the direct drive shaft 202 are multi-purpose functional shafts, which only connect the wheel sets on both sides of the trailer for driving when the trailer body 2 and the load-bearing beam frame 205 are connected to the tractor body.

[0035] The beneficial effects of this utility model on trailers are mainly as follows:

[0036] Firstly, the movable towing and synchronous drive are specifically linked through the movable connection of the trailer beam 1, trailer body 2, and main trailer plate. Specifically, the sleeve head is in a movable connection with the pin seat. When the front and rear drive wheels experience thrust and pull due to uneven terrain, the force is applied to the pin seat, causing upward or downward pulling. When the trailer body 2 components transmit impact to the longitudinal guide rail 108 due to inertia or ground forces, the sleeve head on the pin seat rolls upward and lifts, causing the synchronous towing arm 206 to also lift and buffer. On flat roads... During normal towing, the towing head 111 and the towing arm 206 are positioned close to parallel to the lateral support arm 103. The synchronous drive mode can be transformed from the original four-wheel drive mountain tractor driving the unpowered wheeled trailer to synchronously output power to the wheels of the trailer body 2. The coordination between the trailer beam 1 and the trailer body 2 is more consistent. The consistency of start and stop can reduce unnecessary collision and wear of parts and unnecessary vehicle power limitation. As a result, more directional output can be achieved in mountainous terrain, adapting to the needs of mountain operations. Secondly, the movable wheelset is designed to adapt to active correction: the pin seat is movably mounted on the longitudinal movable arm, the force point of the towing arm 206 is sleeved on the outside of the movable wheelset, the towing arm 206 is connected to the load-bearing beam 205, and the bottom of the load-bearing beam 205 is sleeved with the transverse support arm 103 through the U-shaped stabilizer 204 to achieve vertical buffering. The transverse movement of the sleeve head 111 can be used to adapt to the deflection impact force, that is, when the driving direction deflects, the force point of the sleeve head 111 can deflect within a range, thereby the direct collision torsion of the transverse deflection is released by the movable connection point connection method; wherein, when driving on a flat road, there is a certain driving clearance between the load-bearing beam 205 and the transverse support arm 103, and there is a filling height gap between the upper and lower beams of the U-shaped stabilizer 204 and the transverse support arm 103.

[0037] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
