Problems solved by technology

At present, this structure can be applied to vehicles maintained by people on the vehicle, but it is necessary to adjust the position of the floating end point of the floating lever in real time, which increases the manpower.
At the same time, since the traveling end point of the traveling lever requires a relatively large traveling space, when the traveling lever is greatly inclined, the braking efficiency will inevitably decrease.
[0005] Due to the limited space between the combined brake beam and the lower part of the vehicle, and the braking of the three wheelsets, the braking ratio of the bogie must be very large. The endpoint requires a large range of motion, and the structure is difficult to realize. At the same time, when the brake shoe wears out, the braking efficiency drops greatly

Abstract

The invention relates to the technical field of lorry braking, and provides a three-axle truck foundation braking device. The device comprises a brake force transmission mechanism, a first rocker composition, a second rocker composition, a third rocker composition, a first assembled type braking beam, a second assembled type braking beam and a third assembled type braking beam. Wherein each wheelpair composition of the three-axle truck corresponds to a group of rocker compositions, the brake force transmission mechanism is arranged above the truck frame and connected with the rocker compositions together corresponding to the tree wheel pair compositions, so that an activity endpoint of a horizontal traveling lever and the highest point of the rocker composition are higher than that of the truck frame, and the activity space of the activity endpoint of the traveling lever is not limited by the truck frame structure, and the braking leverage of the truck frame can be reduced, the braking efficiency is high. The invention also provides a three-axle truck.

Description

technical field [0001] The invention relates to the technical field of railway freight car braking, in particular to a three-axle bogie foundation braking device and a three-axle bogie. Background technique [0002] In railway vehicles, the three-axle bogie consists of a frame, a shock absorber, a foundation brake device, three wheel sets and six axle boxes respectively arranged on the outside of the wheels. The use of a three-axle bogie can increase the load capacity of the vehicle and improve Therefore, three-axle bogies are widely used in railway wagons. However, compared with the two-axle bogie, the three-axle bogie has an additional wheel set, and the structure of the three-axle bogie is more complicated, especially the foundation braking device of the three-axle bogie is also more complicated. [0003] Most of the traditional two-axle bogie foundation braking devices of railway freight cars adopt the braking method of middle tie rod or lower tie rod. When the tie rod...
