Hump vehicle reducer

Hump vehicle reducer is mainly used for speed control of hump rolling in railway marshalling yards. The principle of hump reducer is: Hump reducer, also known as static clutch, is a common transmission device. Its principle is to achieve a certain speed ratio between non coaxial lines through the action of friction. The hump reducer mainly consists of input shaft, output shaft, friction ring, pressure plate, and pressure regulator.
The working principle of a Hump vehicle reducer can be divided into three stages: clutch stage, slip stage, and locking stage.
In the clutch stage, the input and output shafts are engaged through friction rings. There are some protrusions on the friction ring that resemble a hump, so it is called a hump reducer. When the input shaft begins to rotate, the torque of the output shaft is transmitted to the friction ring through an external force (such as the drive of a motor). Under the action of friction, the friction ring begins to rotate and drives the output shaft to rotate accordingly. At this stage, the speed of the input and output shafts is the same.
Next, we will enter the sliding stage. When the torque of the output shaft exceeds the limit that the friction ring can withstand, the friction ring will slip. At this point, the hump on the friction ring will come into contact with the pressure plate and transmit it to the pressure regulator, thereby increasing the pressure on the friction ring. At this stage, there will be a certain difference between the speed of the input shaft and the output shaft, that is, the speed of the output shaft is lower than that of the input shaft.
Finally, enter the locking stage. When the pressure on the friction ring increases to a certain extent, the frictional force between the pressure plate and the friction ring will be strong enough to fully lock the output shaft. At this stage, the speed ratio between the input and output shafts is fixed, depending on the number and shape of the humps on the friction ring.
The design of Hump vehicle reducer can achieve different speed ratios by changing the number and shape of humps. In addition, the torque of the output shaft can be adjusted by adjusting the spring force in the pressure regulator and the number of blocks on the pressure plate.
Hump reducers have some advantages. Firstly, it can achieve a wide range of speed ratios while also having a large torque output. Secondly, due to the lack of lubrication and cooling devices, the hump reducer has a small volume, light weight, and simple structure. In addition, during the working process, the reducer will not produce impact and vibration, and its operation is stable and reliable. Finally, the hump reducer is suitable for continuous operation and has shown superiority in some situations that require a longer working life.
However, Hump vehicle reducer also have some drawbacks. Firstly, due to the presence of friction, wear will occur on the friction ring and hump, so regular inspection and replacement are necessary. In addition, when the friction ring and hump are severely worn, the output torque of the reducer will decrease and its lifespan will also be reduced. In addition, the accuracy and efficiency of hump reducers are low, so they are not suitable for some transmission work that requires precision and efficiency.
Overall, Hump vehicle reducer is a common transmission device that achieves a certain speed ratio between non coaxial lines through the action of friction. Its principle is to control the speed difference between the input and output shafts through the hump on the friction ring. Hump reducers have advantages such as simple design, large torque output, stability and reliability, but they also have disadvantages such as wear and low efficiency. In practical applications, it is necessary to select appropriate models of hump reducers according to specific working conditions, and regularly maintain and replace worn parts to ensure the normal operation and long-term use of reducers.

Hump vehicle reducer, anti loosening rolling noise reducing brake track and anti loosening device, our company’s first product, exclusive domestically and internationally, this product is called forged brake caliper. Currently, cast steel brake calipers are used both domestically and internationally, which are prone to breakage.
The advantages of forging brake calipers: using mold components to forge round steel billets in one go without breaking.

The noise reduction brake rail can reduce the high-frequency sharp noise emitted by the wheels and rail surface during braking friction, solving the noise environment of surrounding residents and the needs of operators.
