Description
Technical Field
The invention relates to the technical field of railway vehicles, in particular to a brake device of a three-axle framework type bogie.
Background
The three-axle framework type bogie has heavy bearing, large braking force required by braking, narrow space inside wheels, and no conventional braking device can be installed, and the three-axle framework type bogie with the braking device is not available at present. In order to meet the production requirements and ensure the driving safety of vehicles, a three-axle framework type bogie with a braking device needs to be developed.
Disclosure of Invention
The invention aims to provide a brake device of a three-axle framework type bogie, which solves the problem that a railway vehicle using the three-axle framework type bogie cannot brake.
In order to achieve the purpose, the invention adopts the following technical scheme:
a brake device of a three-axle framework type bogie comprises a first brake beam, a second brake beam, a movable lever, a lower pull rod, a fixed lever, a lifting ring, a positioning plate and a high friction composite brake shoe; the brake beam I and the brake beam II are symmetrically arranged, the middle of the brake beam I is hinged with a movable lever, the middle of the brake beam II is hinged with a fixed lever, the movable lever is hinged with the bottom of the fixed lever through a lower pull rod, the brake beam I is connected with a bogie through a lifting ring, the top of the fixed lever is hinged with the bogie through a positioning plate, and high friction composite brake shoes are symmetrically arranged at two ends of the brake beam I and the brake beam II and respectively correspond to bogie wheels.
The movable lever and the fixed lever are arranged at an acute angle with the transverse direction of the bogie.
Compared with the prior art, the invention has the beneficial effects that:
the invention solves the problem that the railway vehicle using the three-axle framework type bogie can not be braked. The safety performance of the railway vehicle is improved.
Drawings
FIG. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a top view of the present invention.
Fig. 3 is a schematic diagram of the application of the present invention.
Fig. 4 is a side view of the application of the present invention.
In the figure: the brake comprises a first brake beam 1, a second brake beam 2, a movable lever 3, a lower pull rod 4, a fixed lever 5, a lifting ring 6, a positioning plate 7 and a high friction composite brake shoe 8.
Detailed Description
The following further describes embodiments of the present invention with reference to the accompanying drawings:
referring to fig. 1-4, a brake device of a three-axle frame bogie comprises a first brake beam 1, a second brake beam 2, a movable lever 3, a lower pull rod 4, a fixed lever 5, a lifting ring 6, a positioning plate 7 and a high friction composite brake shoe 8; the brake beam I1 and the brake beam II 2 are symmetrically arranged, the middle of the brake beam I1 is hinged with a movable lever 3, the middle of the brake beam II 2 is hinged with a fixed lever 5, the movable lever 3 is hinged with the bottom of the fixed lever 5 through a lower pull rod 4, the brake beam I1 is connected with a bogie through a hanging ring 6, the top of the fixed lever 5 is hinged with the bogie through a positioning plate 7, and high friction synthetic brake shoes 8 are symmetrically arranged at two ends of the brake beam I1 and the brake beam II 2 and respectively correspond to bogie wheels.
The movable lever 3 and the fixed lever 5 are arranged at an acute angle with the transverse direction of the bogie.
When the vehicle brakes, the upper end of the movable lever 1 is pushed by the braking force of the vehicle to move, the brake beam I1 arranged in the middle of the movable lever 3 moves along with the movable lever I1, the high friction synthetic brakes 8 arranged at two ends of the brake beam I1 tightly hold bogie wheels, meanwhile, the lower pull rod 4 arranged at the lower part of the movable lever 3 moves along with the movable lever I to drive the fixed lever 5 connected with the other end to move, the brake beam II 2 connected with the lower part of the fixed lever 5 moves, and the high friction synthetic brakes 5 arranged at two ends of the brake beam II 2 tightly hold wheels at the other side, so that the vehicle brakes are realized.
The foregoing is considered as illustrative only of the principles of the invention and is not to be in any way limiting, since all equivalent changes and modifications are intended to be included within the scope of the appended claims.
