Description

Technical Field

[0001] The utility model relates to the technical field of application of tourist sightseeing vehicles, in particular to a bucket-type pneumatic brake device for off-road tourist sightseeing vehicles. Background Art

[0002] Existing braking systems for off-road tourist vehicles are mostly electric transmission brakes, which have a single braking mode and are insufficient in stopping the vehicle. In the event of a power outage, the brake locking effect is significantly reduced, posing a potential risk of rolling accidents. Therefore, to address these issues, a bucket-type pneumatic brake system for off-road tourist vehicles is proposed. Utility Model Content

[0003] The purpose of the present utility model is to provide a bucket-type pneumatic brake device for off-road tourist sightseeing vehicles in order to solve the above problems.

[0004] The utility model achieves the above-mentioned purpose through the following technical scheme: a barrel-type pneumatic brake device for off-road tourist sightseeing vehicles, comprising a barrel-shaped cylinder, a U-shaped part, a brake linkage rod, a ratchet, a U-shaped frame, a rotating shaft, a rectangular steel ring, a bearing, a regulating cylinder and a flange. A U-shaped part is installed at the outer end of the output shaft of the barrel-shaped cylinder, and the U-shaped part is rotatably connected to one end of the brake linkage rod. The middle part of the brake linkage rod is rotatably connected to the two ends of the U-shaped frame, and a ratchet is installed on one side of the middle part of the brake linkage rod. A non-return limiting structure is formed between the ratchet and one end of the rectangular steel ring, and a bearing is installed in the middle position of the top of the rectangular steel ring, and the bearing is connected to the output end of the regulating cylinder.

[0005] Preferably, rotating shafts are fixedly installed on both sides of the middle of the rectangular steel ring, and one end of the rotating shaft is connected to the corresponding part of the U-shaped frame.

[0006] Preferably, a torsion spring is mounted on the rotating shaft.

[0007] Preferably, a flange is installed at the end of the middle portion of the U-shaped frame.

[0008] Preferably, the other end of the brake linkage rod is connected to the linkage end of an external brake device.

[0009] Preferably, an air inlet pipe and an air outlet pipe are distributed on the barrel-shaped cylinder.

[0010] Compared with the prior art, the advantages of the present invention are: by putting the output shaft on the barrel-shaped cylinder in a push-pull state, the brake linkage rod connected via the U-shaped part is in a push-pull side-rotation state, thereby realizing pneumatic braking. By partially positioning one end of the rectangular steel ring connected to the regulating cylinder in the ratchet groove corresponding to the ratchet, the brake linkage rod is effectively prevented from resetting after a failure of the barrel-shaped cylinder, thereby ensuring that the brake is locked. By extending the regulating cylinder to push the top end of the rectangular steel ring connected via the bearing forward, one end of the rectangular steel ring is helped to disengage from the ratchet, so that the pneumatic braking can operate normally after the pneumatic system is restored.
