Description

Technical Field

[0001] This utility model relates to the field of wheelset technology, specifically a steerable wheelset with lubrication function. Background Technology

[0002] Wheelsets are key components of railway vehicles, urban rail transit vehicles, and some special vehicles. They directly bear the weight of the vehicle and propel it through interaction with the track. The performance and reliability of wheelsets have a crucial impact on the vehicle's operational safety, stability, and service life.

[0003] During vehicle operation, especially when navigating curves or making small-radius turns, the steering capability of traditional wheelsets is often limited. This can lead to increased rolling resistance, accelerated wheel and rail wear, and even affect the vehicle's operational safety and efficiency. For example, in complex lines of mountain railways or urban rail transit systems, where vehicles require frequent turning maneuvers, the insufficient steering performance of traditional wheelsets becomes even more apparent.

[0004] Under high-speed rotation and heavy loads, the bearings and journals of wheelsets are prone to wear and heat generation. Poor lubrication will further exacerbate wear, reduce wheelset lifespan, and increase maintenance costs and vehicle downtime. Furthermore, insufficient lubrication can lead to wheelset malfunctions, affecting normal vehicle operation and even causing safety accidents. For example, in high-temperature environments or long-distance rail transport, unresolved wheelset lubrication issues can severely impact vehicle reliability. Utility Model Content

[0005] The purpose of this invention is to provide a steering wheelset with lubrication function to solve the problems of poor steering ability and insufficient wheel lubrication mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a steerable wheelset with lubrication function, comprising a mounting frame and wheels, wherein the wheels are mounted on the left and right sides of the mounting frame, and a steering device is provided inside the mounting frame;

[0007] The reversing device includes a reversing motor, a gear, a rack, a rotating shaft, and a mounting frame. The reversing motor is mounted above the mounting frame. The gear is connected to the output end of the reversing motor and located inside the mounting frame. The rack is mounted inside the mounting frame and meshes with the outer surface of the gear. The rotating shaft is fixedly connected to the left and right ends of the rack. The mounting frame is mounted on the left and right ends of the rack and rotatably connected to the inside of the mounting frame. The mounting frame is fixedly connected to the underside of the vehicle. The reversing motor drives the gear to rotate, thereby moving the rack and ultimately changing the direction of the mounting frame and the wheels.

[0008] Preferably, the mounting bracket has a threaded hole on its upper part, and the mounting bracket and the reversing motor are connected by bolts through the threaded hole, which facilitates the maintenance and replacement of the reversing motor and improves the convenience of the device.

[0009] Preferably, a wheel axle is fixedly connected to the side of the fixing frame away from the mounting frame, and the wheel is rotatably connected to the outer surface of the wheel axle. A limit ring is installed on the outer surface of the wheel axle near the wheel, and a spring pin is fixedly connected to the inner surface of the limit ring. A groove is formed on the outer surface of the wheel axle near the limit ring, and a locking slot is formed inside the groove. The locking slot matches the spring pin, and the material is limited by the limit ring. The spring pin is engaged in the locking slot to prevent the limit ring from moving.

[0010] Preferably, the wheel axle has a cavity inside the end near the limiting ring, and a pressing block is installed inside the cavity. One end of the pressing block extends from a shaft, and the pressing block is rotatably connected to the end of the wheel axle near the limiting ring via the shaft. A knob is fixedly connected to the end of the shaft away from the pressing block. By rotating the knob, the pressing block is rotated to press the spring pin, and at the same time, the limiting ring is pulled to disengage the spring pin from the retainer, so that the limiting ring can be removed for wheel maintenance and replacement. The operation is convenient.

[0011] Preferably, a lubricating oil box is fixedly connected above the mounting bracket. A lead screw motor is fixedly installed on the side of the lubricating oil box near the mounting bracket. An oil inlet is fixedly connected above the lubricating oil box. A lead screw is connected to the output end of the lead screw motor and is located inside the lubricating oil box. A push plate is threadedly connected to the outer surface of the lead screw and slidably connected to the inside of the lubricating oil box. A connecting pipe is fixedly connected to the side of the lubricating oil box near the wheel and communicates with the inside of the lubricating oil box. An oil inlet is opened at one end of the wheel axle near the mounting bracket, and the other end of the connecting pipe communicates with the oil inlet. A sealing ring is fixedly connected inside the lubricating oil box on the outer surface of the lead screw. The lead screw motor drives the lead screw to rotate a certain number of revolutions, thereby causing the push plate to advance a specified distance, pressing a certain amount of lubricating oil into the oil inlet through the connecting pipe, and finally flowing out from the lubrication hole on the surface of the wheel axle to lubricate the wheel axle and the inner surface of the wheel, improving service life. The sealing ring can prevent oil from overflowing.

[0012] Preferably, the inner surface of the wheel is provided with a guide groove, which allows the lubricating oil to flow better and improves the lubrication effect.

[0013] Preferably, a mounting block is fixedly connected above the mounting bracket, and an infrared speedometer is fixedly mounted above the mounting block. A marking groove is provided on the side of the wheel near the infrared speedometer. The infrared speedometer is a DM6234P+ model. The infrared speedometer is connected to the lead screw motor via a signal line. The wheel speed is determined by detecting the number of times the marking groove passes through per unit time. Once a certain speed is reached, a signal is sent to the lead screw motor via the signal line to lubricate the wheel axle and reduce unnecessary lubricant consumption.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This lubricated steerable wheelset uses a reversing motor to drive a gear, which in turn moves a rack, ultimately changing the direction of the mounting bracket and wheels. A limit ring restricts the material, and a spring pin engages with the slot to prevent the limit ring from moving. By rotating the knob, the extrusion block rotates to compress the spring pin, while simultaneously pulling the limit ring to disengage the spring pin from the slot, allowing the limit ring to be removed for wheel maintenance and replacement. The operation is convenient.

[0016] 2. This steerable wheelset with lubrication function uses a lead screw motor to rotate a certain number of revolutions, causing the push plate to advance a specified distance. A certain amount of lubricating oil is forced into the oil inlet through the connecting pipe and finally flows out from the lubrication hole on the wheel axle surface to lubricate the wheel axle and the inner surface of the wheel, improving service life. The sealing ring prevents oil leakage, and the guide groove allows the lubricating oil to flow better, improving the lubrication effect. The wheel speed is determined by the number of times the marker groove passes through per unit time using an infrared speed measuring instrument. Once a certain speed is reached, a signal is sent to the lead screw motor via a signal line to activate the lubrication of the wheel axle, reducing unnecessary lubricating oil consumption.

[0023] Example 1: Addressing the current issues of poor steering ability and insufficient wheel lubrication in wheelsets, this example provides a steering wheelset with lubrication functionality. Please refer to [link / reference]. Figures 1-4 The embodiment provides a steerable wheelset with lubrication function, which enables the wheelset to turn freely within a certain angle, and allows for quick loading and unloading of the wheels, making operation convenient.

A cavity is opened inside the wheel axle 307 near the limit ring 5. A pressing block 503 is installed inside the cavity. A shaft extends from one end of the pressing block 503. The pressing block 503 is rotatably connected to the end of the wheel axle 307 near the limit ring 5 through the shaft. A knob 504 is fixedly connected to the end of the shaft away from the pressing block 503.

[0026] In this embodiment, the gear 201 is driven to rotate by the reversing motor 2, which in turn drives the rack 202 to move, ultimately causing the fixing frame 204 and the wheel 101 to change direction. The material is limited by the limiting ring 5, and the spring pin 501 is locked into the slot 502 to prevent the limiting ring 5 from moving. By rotating the knob 504, the pressing block 503 is rotated to press the spring pin 501, and at the same time, the limiting ring 5 is pulled to make the spring pin 501 disengage from the slot 502 so that the limiting ring 5 can be removed for maintenance and replacement of the wheel 101. The operation is convenient.

[0027] Example 2: Based on Example 1, please refer to... Figures 1-4 It can provide quantitative lubrication to the wheel axle and the inner surface of the wheel, and the lubrication device is activated only at a certain speed to reduce lubricant consumption. A lubricant box 3 is fixedly connected to the top of the mounting bracket 204. A screw motor 302 is fixedly installed on the side of the lubricant box 3 near the mounting bracket 1. An oil inlet 301 is fixedly connected to the top of the lubricant box 3. A screw 303 is connected to the output end of the screw motor 302 and is located inside the lubricant box 3.

A connecting pipe 305 is fixedly connected to the side of the lubricant box 3 near the wheel 101 and communicates with the inside of the lubricant box 3. An oil inlet 306 is opened at one end of the wheel axle 307 near the mounting bracket 204. The other end of the connecting pipe 305 communicates with the oil inlet 306. A sealing ring is fixedly connected to the inside of the lubricant box 3 on the outer surface of the screw 303. A guide groove 308 is opened on the inner surface of the wheel 101.

The infrared speed measuring instrument 4 is connected to the lead screw motor 302 through a signal line.

[0029] In this embodiment, the lead screw motor 302 drives the lead screw 303 to rotate a certain number of revolutions, thereby causing the push plate 304 to advance a specified distance. A certain amount of lubricating oil is forced into the oil inlet 306 through the connecting pipe 305, and finally flows out from the lubrication hole on the surface of the wheel axle 307 to lubricate the inner surface of the wheel axle 307 and the wheel 101, thereby improving service life. The sealing ring can prevent oil from overflowing, and the guide groove 308 can make the lubricating oil flow better and improve the lubrication effect. The rotation speed of the wheel 101 is determined by detecting the number of times the mark groove 402 passes through per unit time using the infrared speed measuring instrument 4. After reaching a certain rotation speed, a signal is sent to the lead screw motor 302 through the signal line to make it work to lubricate the wheel axle 307, reducing unnecessary consumption of lubricating oil.

[0030] Working principle: The reversing motor 2 drives the gear 201 to rotate, which in turn drives the rack 202 to move, ultimately changing the direction of the fixed frame 204 and the wheel 101. The material is limited by the limiting ring 5, and the spring pin 501 is locked into the slot 502 to prevent the limiting ring 5 from moving. By rotating the knob 504, the pressing block 503 is rotated to press the spring pin 501, and at the same time, the limiting ring 5 is pulled to make the spring pin 501 disengage from the slot 502 so that the limiting ring 5 can be removed for maintenance and replacement of the wheel 101. The operation is convenient. The lead screw motor 302 drives the lead screw 303 to rotate a certain number of revolutions, thereby causing the push plate 304 to advance a specified distance. A certain amount of lubricating oil is forced into the oil inlet 306 through the connecting pipe 305, and finally flows out from the lubrication hole on the surface of the wheel axle 307 to lubricate the inner surface of the wheel axle 307 and the wheel 101, thereby improving service life. The sealing ring can prevent oil from overflowing, and the guide groove 308 can make the lubricating oil flow better and improve the lubrication effect. The infrared speed measuring instrument 4 detects the number of times the mark groove 402 passes through per unit time to determine the speed of the wheel 101. After reaching a certain speed, a signal is sent to the lead screw motor 302 through the signal line to make it work to lubricate the wheel axle 307 and reduce unnecessary lubricating oil consumption.
