Embodiment Construction

[0020] Such as figure 1 , figure 2 , image 3 As shown, the rail vehicle has an axle box structure with both anti-skid and monitoring functions, including an axle box body 1 that is sleeved on the end of the wheel axle through a bearing, and an axle box gland 6 that is fixed on the outside of the wheel axle end through a first fastening screw 131. , and the gear 7 fixed to the outer end of the axle box gland by the second fastening screw 132, in this implementation, the gap between the tooth tip of the gear and the signal sensor and the speed sensor is 0.9 ± 0.5mm. The gear has 100 teeth and a modulus of 1.5. The outer end of the axle box body 1 is fixed with an axle box cover 8, and the axle box cover 8 is provided with a speed sensor installation interface 19 far away from the center of the bogie and a signal sensor installation interface 20 close to the center of the bogie. Viewed from the axle end, the speed sensor installation interface The central line of 19 and the ...

Abstract

The invention relates to an axle box structure with anti-skid and monitoring functions and used for a railway vehicle. The axle box structure comprises an axle box body installed at the axle end through a bearing in a sleeving mode, an axle box pressing cover fixed on the exterior of an axle end and a gear fixed on the outer end of the axle box pressing cover. A axle box cover is fixed at the outer end of the axle box body. A speed sensor installing connecting opening away from the center of a steering frame and a signal sensor installing connecting opening being close to the center of the steering frame are formed in the axle box cover. From the view of the axle end, an angle a facing downward is formed between the central line and the horizontal line of the speed sensor installing connecting opening, an angle b facing downward is formed between the central line and the horizontal line of the signal sensor installing connecting opening, the value range of a is 7-11 degrees, and the value range of b is 8.5-11.5 degrees. According to the axle box structure with the anti-skid and monitoring functions and used for the railway vehicle, the size of a matched position of an axle box cover labyrinth slot and the axle box body keeps unchanged, and a boss connecting opening for anti-skid equipment and a boss connecting opening for signal equipment are integrated on the axle box cover, so that the purpose that the anti-skid equipment and the signal equipment can be simultaneously installed on the axle box cover is achieved.

Description

technical field [0001] The invention relates to an axle box structure for an urban rail subway vehicle bogie, and belongs to the technical field of urban rail subway vehicle bogies. Background technique [0002] The bogie wheel-to-axle box system of urban rail subway vehicles is a very important system component of the bogie. Various other static and movement forces are exerted, and the forces are very complicated. The wheel-to-axle box system consists of a wheel set and an axle box device. The axle box device is responsible for collecting and transmitting data on the operation of the bogie. Therefore, the wheel-to-axle box system is one of the key components that affect the safety of vehicle operation. [0003] The existing axle box covers are divided into ordinary axle box covers, anti-skid axle box covers, and signal axle box covers according to the different axle end equipment. Technical requirements; in addition, the signal equipment is not compatible with general spe...
