Technical Field

[0001] The utility model relates to a transport vehicle suitable for freight transportation. Background Art

[0002] Chinese patent document CN106627303B discloses a multifunctional agricultural management machine. The machine comprises a top plate fixed behind the rear support beam of the cargo box, a handrail and an engine mounted on the top plate, and an operating mechanism integrated into the top of the handrail. The engine's output shaft is connected to a hydraulic pump station via a flange, which drives the oil cylinder. A driving pulley is mounted on the engine's output shaft and connected to a driven pulley on the transmission input shaft via a belt. The transmission is located on a transmission support plate, with the top plate enclosing the upper portion of the transmission. Each side of the top plate is connected to the transmission via a bolt. Transmission brackets are symmetrically located on the left and right sides of the transmission, connecting the transmission to the rear end of the frame longitudinal beam via the brackets. The transmission has two symmetrically arranged output terminals, each connected to an output half-shaft. A driving wheel is mounted on each output half-shaft, connected to a guide wheel on the same side via a crawler track. Multiple supporting rollers are positioned front to back between the driving wheel and the guide wheel on the same side. These rollers press against the crawler track, and their axles are fixed to the frame. A retractable foot pedal is provided at the rear of the top plate.

[0003] In the prior art, the engine uses a belt drive to transmit power to the gearbox to achieve the movement of the entire machine. However, when working in a wading or rainy environment, the belt drive is prone to slipping, resulting in difficulty in moving. In addition, the belt drive requires frequent maintenance, which increases the burden of use. Utility Model Content

[0004] The purpose of the utility model is to provide a transport vehicle to solve the problem in the prior art that the transport vehicle is prone to walking difficulties when working in a wading or rainy environment.

[0005] In order to achieve the above-mentioned purpose, the basic scheme of the present utility model provides a transport vehicle, including a frame, a traveling mechanism is provided on both sides of the frame, a traveling transmission bridge is provided at one end of the frame, the traveling transmission bridge is connected to the prime mover, the output shaft of the prime mover is connected to the traveling transmission bridge through a gear transmission mechanism, the gear transmission mechanism is sealed in the housing of the traveling transmission bridge, and the prime mover is sealed to the upper part of the housing of the traveling transmission bridge.

[0006] The beneficial effects of this basic solution are as follows: the prime mover transmits power to the travel transmission bridge through the gear transmission mechanism, and the travel transmission bridge then transmits power to the travel mechanism, so that the power of the prime mover can be stably transmitted to the travel mechanism; at the same time, the housing of the travel transmission bridge is used to protect the gear transmission mechanism, which can reduce the impact of external debris on the gear transmission mechanism; at the same time, the prime mover and the upper part of the housing of the travel transmission bridge are sealed, which can prevent water from entering the prime mover when the transport vehicle is wading through water and affecting its normal operation. Compared with the existing technology, this solution can stably transmit the power of the prime mover to the travel mechanism without being affected by water when wading through water or rainy conditions, thereby solving the problem of the existing technology that transport vehicles are prone to difficulty in walking when used in wading through water or rainy conditions, and improves the wading ability of the transport vehicle and reduces maintenance operations.

[0007] Preferably, the gear transmission mechanism is located on the upper side of the bridge tube shaft of the traveling transmission bridge. With such an arrangement, the gear transmission mechanism is kept as far away from the ground as possible, thereby further reducing the possibility of water or other debris contacting the gear transmission mechanism during wading operations and affecting the reliability of the gear transmission mechanism.

[0008] Preferably, the output shaft of the prime mover is arranged perpendicularly to the axle tube axis of the travel transmission axle. Such an arrangement facilitates the installation and arrangement of the prime mover.

[0009] Preferably, a fixing bracket is connected to the frame for clamping and fixing the prime mover in the direction of rotation of the prime mover. With such an arrangement, the fixing bracket supports the prime mover, thereby reducing the torsional impact of the prime mover on the transmission case during operation, which is conducive to improving the stability of the entire machine.

[0010] Preferably, the traveling mechanism includes a drive wheel drivingly connected to the travel transmission bridge, and guide wheels rotatably connected to the vehicle frame. Tracks are connected between the drive wheel and the guide wheels, and the guide wheels are double-sided guide wheels. This arrangement forms a tracked traveling mechanism, which improves the transport vehicle's maneuverability. Furthermore, the double-sided guide wheels enhance the durability of the tracks and reduce maintenance costs of the traveling mechanism.

[0011] Preferably, a floating wheel is provided between the driving wheel and the guide wheel to cooperate with the crawler track, and the floating wheel is movably connected to the vehicle frame. With this arrangement, the crawler track can better conform to the ground through the movement of the floating wheel, thereby making the transport vehicle more stable even when traveling on bumpy ground, thereby improving the transport vehicle's maneuverability and comfort.

In this embodiment, the running mechanism comprises a drive wheel 6 and guide wheels 3 rotatably connected to the frame 2. Tracks 5 are connected between the drive wheel 6 and the guide wheels 3, forming a track-type running mechanism. In this embodiment, the guide wheels 3 are bilateral. Furthermore, floating wheels 4 are disposed between the drive wheel 6 and the guide wheels 3, cooperating with the tracks 5 and movably connected to the frame 2.
