Brakes and Vehicles

Abstract

The invention provides a braking device and a vehicle. The braking device comprises an air braking cylinder, a rotating lever, a shearing structure, a brake shoe clearance adjustment machine and two vacuum braking cylinders, wherein a piston rod of each of the vacuum braking cylinders is connected with one end of the rotating lever; a piston rod of the air braking cylinder is connected with the other end of the rotating lever and a first input end of the shearing structure; a second input end of the shearing structure is connected with one end, away from the piston rod, of the air braking cylinder, and a first output end of the shearing structure is connected with one end of the brake shoe clearance adjustment machine, and a second output end of the shearing structure is connected with a vehicle steering frame device; and the other end of the brake shoe clearance adjustment machine is connected with the vehicle steering frame device. The braking device can realize mutual switching of an air braking system and a vacuum braking system without disassembling and assembling any parts and components, and is simple to operate. Besides, the entire braking device only needs one the brake shoe clearance adjustment machine, and is low in maintenance cost and an off-the-vehicle mounting space is saved.

Description

technical field [0001] The embodiments of the present invention relate to the mechanical field, and in particular to a braking device and a vehicle. Background technique [0002] With the rapid development of my country's railway high-speed passenger transport and heavy-duty trucks, higher requirements are put forward for the reliability and safety of the vehicle braking system. [0003] At present, domestic vehicles generally adopt a vacuum-air hybrid braking foundation braking device for vehicle braking. figure 1 The schematic diagram of the mechanism of the foundation braking device adopted in the prior art, such as figure 1 As shown, the basic braking device includes a transition lever 1, a brake shoe clearance adjuster 2, a vacuum brake cylinder 3, an air brake cylinder 4, a brake lever 5, a long rotating arm 6, a rotating drum 7, and a short rotating arm 8 , connecting rod 9, brake shoe clearance adjuster 10. When the air brake is used, the brake shoe clearance adju...

Problems solved by technology

[0004] However, the basic brake device of the vacuum-air hybrid brake needs three brake shoe clearance adjusters, the manufacturing and maintenance costs are high, and the required installation space under the vehicle is large. Moreover, when the air brake system and the vacuum brake system are switched to each other, It is necessary to disassemble and assemble the connecting rod or the brake shoe clearance adjuster, and the operation is complicated
