Description

Technical Field

[0001] This utility model belongs to the field of truck auxiliary equipment, specifically relating to an inter-wheel booster for truck escape. Background Technology

[0002] As a core tool in the freight industry, heavy-duty trucks face extremely complex daily hauling scenarios. They may traverse construction access roads on the outskirts of cities, with surfaces riddled with gravel and potholes; they may drive on muddy, poorly supported country lanes after the rainy season; and they may transport goods on winding temporary passes in mountainous areas, where roads are narrow and prone to landslides, flooding, and other emergencies. In these complex scenarios, heavy-duty trucks are highly susceptible to getting stuck if they encounter unexplored mud pits.

[0003] Heavy trucks themselves have a curb weight of tens of tons, and when fully loaded with cargo, the total weight can often reach tens or even hundreds of tons. When stuck in a mud pit, the enormous weight causes the truck's drive wheels to sink deep into the mud. Due to the combined pressure of its own weight and the weight of the cargo, the torque required to start the engine far exceeds its normal output range, causing the engine to fail to start smoothly. Naturally, it cannot turn the tires, leaving the truck unable to move in the mud pit.

[0004] In this situation, common external assistance methods include contacting professional heavy-duty tow trucks for towing or calling in engineering vehicles with relevant equipment for rescue, which is not only costly but also time-consuming. Utility Model Content

[0005] To address the aforementioned problems, the purpose of this utility model is to provide an inter-wheel booster for truck evacuation, which solves the problem that heavy trucks stuck in ditches can only passively wait for rescue because their engines cannot be started.

[0006] This utility model is achieved through the following technical solution:

[0007] An inter-wheel booster for truck escape includes a gear transmission mechanism. The power output shaft of the gear transmission mechanism is connected to a rotating shaft via a coupling. A rotating shaft sleeve is fixedly sleeved in the middle of the rotating shaft. Bearings are rotatably sleeved on both sides of the rotating shaft. Bearing seats are fixedly installed on the bearings. A lifting structure is fixedly connected to the bearing seats.

[0008] Furthermore, the lifting structure includes a lower threaded rod fixedly mounted on the bearing seat and an upper threaded rod fixedly mounted on the chassis. The lower threaded rod and the upper threaded rod are respectively provided with reverse threads. The lower threaded rod and the upper threaded rod are rotatably connected by a threaded sleeve. The upper and lower sections of the threaded sleeve are respectively provided with internal threads that match the lower threaded rod and the upper threaded rod.

[0009] Furthermore, the gear transmission mechanism includes a gearbox, which is mounted on a bearing seat on one side of the rotating shaft. A large gear and a small gear are respectively installed in the gearbox through a power output shaft and a small gear shaft. The large gear and the small gear mesh with each other. A square hole for connecting an external drive mechanism is opened on the small gear shaft.

[0010] Furthermore, the upper threaded rod is fixedly connected to the vehicle chassis by bolts.

[0011] Furthermore, the upper half of the threaded rod is threaded, and the lower half is provided with a threaded hole for fixing to the bearing seat.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention places the bearing housing between the two rows of tires on a truck and uses a lifting structure to move the bearing housing up and down, thereby driving the shaft and shaft sleeve to move downwards. This causes the shaft sleeve to press tightly against the two rows of tires. The power of the gear transmission mechanism is transmitted to the shaft through a coupling. The torque is amplified by the difference in the number of gear teeth, driving the shaft and the shaft sleeve fixed to the shaft to rotate, thereby rotating the tires and gradually freeing the truck from its predicament.

[0014] The lifting structure of this utility model utilizes the reverse thread design of the upper and lower threaded rods. The upper threaded rod is used to connect to the chassis of the vehicle by bolts, and the lower threaded rod is connected to the bearing seat. When the sleeve is rotated, due to the reverse thread, the upper and lower threaded rods extend and retract synchronously, thereby changing the vertical position of the bearing seat, gearbox, shaft, and shaft sleeve.

[0015] The small gear shaft of this utility model has a square hole for connecting an external drive mechanism (such as a motor or a manual wrench). Power is input from the small gear shaft, and after the torque is increased by the large gear, it drives the rotating shaft to rotate. The rotating shaft drives the rotating shaft sleeve fixedly installed on it to rotate, which meets the requirements of low speed and high torque working conditions. Attached Figure Description

[0020] The present invention will be further described in detail below with reference to specific embodiments. The description is for explanation and not limitation of the present invention.

[0021] refer to Figure 1 As shown, this utility model provides an inter-wheel booster for truck escape, including a gear transmission mechanism 5. The power output shaft of the gear transmission mechanism 5 is connected to a rotating shaft 1 through a coupling. A rotating shaft sleeve 2 is fixedly sleeved in the middle of the rotating shaft 1. Bearings 3 are rotatably sleeved on both sides of the rotating shaft 1. Bearing seats 4 are fixedly installed on the bearings 3. A lifting structure is fixedly connected to the bearing seats 4.

[0022] The lifting structure includes a lower threaded rod 8 fixedly mounted on the bearing seat 4 and an upper threaded rod 7 fixedly mounted on the vehicle chassis. The upper threaded rod 7 is fixedly connected to the vehicle chassis by bolts. (Refer to...) Figure 2 As shown, the upper half of the lower threaded rod 8 is threaded, and the lower half is provided with a threaded hole 10 for fixing with the bearing seat 4; the lower threaded rod 8 and the upper threaded rod 7 are respectively provided with reverse threads, and the lower threaded rod 8 and the upper threaded rod 7 are rotatably connected by a threaded sleeve 9. The upper and lower sections of the threaded sleeve 9 are respectively provided with internal threads that match the lower threaded rod 8 and the upper threaded rod 7; the lower threaded rod 8 and the upper threaded rod 7 are engaged by the threaded sleeve 9, and the relative movement between the two can be achieved by rotating the threaded sleeve 9.

[0023] refer to Figure 3 As shown, the gear transmission mechanism 5 includes a gearbox 5-3, which is mounted on a bearing seat 4 on one side of the rotating shaft 1. A large gear 5-2 and a small gear 5-1 are respectively installed in the gearbox 5-3 through a power output shaft and a small gear shaft. The large gear 5-2 and the small gear 5-1 mesh with each other. A square hole for connecting an external drive mechanism is opened on the small gear shaft.

[0024] The working principle of the various parts of this utility model is as follows:

[0025] I. Gear Transmission Mechanism

[0026] It includes large and small gears, gearbox, and shaft components, forming the core of power transmission:

[0027] The pinion 5-1 and the gear 5-2 are placed inside the gearbox 5-3 to form a closed transmission space; the gearbox 5-3 is mounted on a bearing seat 4 on one side of the shaft, and the bearing seat 4 provides stable support.

[0028] The rotating shaft 1 is installed and positioned via bearing seats 4 and bearings 3 on both sides. The power output shaft of the large gear is connected to the rotating shaft 1 through a coupling. The small gear is assembled through an independent small gear shaft. The shaft system cooperates with the gearbox 5-3 and bearing seats 4 to ensure transmission stability.

[0029] The pinion shaft has a square hole for connecting to an external drive (such as a motor or manual wrench). Power is transmitted to the large gear through the meshing of the pinion, and the torque is amplified by the difference in the number of gear teeth, driving the shaft and the rollers fixed on the shaft to rotate, thus meeting the requirements of low-speed and high-torque working conditions.

[0030] II. Lifting Structure

[0031] The roller height can be adjusted by using a sleeve and a reverse threaded rod design.

[0032] The sleeve has two reverse threads inside, which mate with the upper and lower threaded rods respectively; the upper threaded rod 7 is connected to the chassis by bolts, and the lower threaded rod 8 is connected to the bearing seat 4, forming a force transmission path of "chassis-lifting structure-bearing seat".

[0033] When the threaded sleeve 9 is rotated, the upper and lower threaded rods extend and retract synchronously due to the reverse of the thread, changing the vertical position of the bearing seat 4 (and gearbox 5-3, shaft 1, shaft sleeve 2), flexibly adjusting the height and pressure of the shaft sleeve 3 and the tire to adapt to different working scenarios (such as adjusting the height of the roller support when the vehicle is loaded, and leveling when the equipment is debugged).

[0034] This utility model's overall system optimizes power output through gear transmission, and its lifting structure adapts to the height requirements of working conditions. It can be applied to scenarios such as auxiliary support / drive for special vehicles and height-adjustable conveying of production line equipment, achieving a composite function of power transmission and position adjustment through mechanical structure.

[0035] The working principle of this utility model:

[0036] In use, the upper threaded rod 7 is fixed to the chassis with bolts. When the threaded sleeve is rotated, the upper and lower threaded rods extend and retract synchronously due to the reverse thread design, which can change the vertical position of the bearing seat and thus adjust the height of the shaft sleeve. The shaft sleeve is placed between the two rows of tires of the truck through the lifting structure and presses the two rows of tires tightly. At the same time, the external drive mechanism (such as a motor, manual wrench, etc.) is connected to the square hole on the pinion shaft to drive the pinion to rotate. The large gear and the pinion mesh with each other. The rotation of the pinion will drive the large gear and the entire gear transmission mechanism to operate. The power output shaft of the gear transmission mechanism transmits torque to the shaft through the coupling, causing the shaft to start rotating. The rotation of the shaft drives the shaft sleeve to rotate, thereby rotating the tires and gradually getting the truck out of trouble.
