Discuss the bogie of linear motor(linear motor) subway. The small editor has reported many times on the linear motor(linear motor) subway. This is a new type of subway. It has the characteristics of small adaptability, strong climbing ability, strong curve passing ability, and low noise. It is reported that the linear motor(linear motor) driven subway has been operating in Japan and China for many years. In 2002, China successfully produced a magnetic levitation train dragged by linear motor(linear motor). Now more than a decade has passed. Many cities in China have such subways operating, such as Guangdong Line 4, No. 5 and No. 6, and Beijing Airport Line.
When it comes to linear Motors(linear Motors) subways, we have to talk about the bogies of such subways. The bogies are two-axle bogies. Each bogie is driven by a linear motor(linear motor). The linear motor(linear motor) is installed on the bogie axle box by means of a full suspension through a suspension beam, and the longitudinal force between the primary body and the bogie between the linear motor(linear motor) and the bogie passes through the longitudinal traction rod. To achieve, The frame overlooks into a "head" shape structure, adopts a box-type all-steel plate welding structure, and the frame side beam is welded by a U-shaped cross-sectional pressure-type upper and lower cover plate assembly. It is a mid-concave fish-bellied box type mechanism. In order to ensure the bending and torsion resistance of the side beams, the wheel pair adopts a built-in, automatic disk external structure, simplifying the structure and reducing the weight. A tapered rubber spring suspension is arranged between the axle box and the frame. A series of suspension requires a banana spring with a large stiffness. A secondary suspension of the air spring is arranged between the frame and the pillow. The secondary suspension consists of an air spring body and an emergency spring, and the vertical direction is well nonlinear.
Kunshan Tongmao Electronics Co., Ltd. has a history of ten years since its establishment. It has always adhered to the concept of "honest management" to provide customers with high-quality products. In addition, while continuing to develop steadily, Tongmao also actively responds to the call of the government and is enthusiastic about public welfare undertakings. If one day Tongmao's linear motor(linear motor) can contribute to the motherland's subway business, Tongmao is quite happy.
