Problems solved by technology

[0005] However, the piston stroke of the brake cylinder of traditional trucks is relatively large, and the two-way automatic adjustment of the brake shoe clearance adjuster not only wastes the function, but also has a bulky structure and large external dimensions, which can no longer meet the loading requirements of the disc brake device.

Abstract

The invention discloses a unit brake cylinder with a hand brake device, which comprises an integral diaphragm, a piston composition, a cylinder body composition, a cylinder head composition, a sealing gasket, a sealing ring, a support ring, a lubricating sleeve, a relief spring, a hand Brake lever, push iron, dust cover, one-way automatic adjustment device for brake pad clearance, manual adjustment device for brake pad clearance, push iron is fixedly connected to piston rod, hand brake lever is connected to hand brake fixed on cylinder head Seat pin connection, which not only realizes the bidirectional action of force during hand braking, but also avoids the occurrence of stagnation. The one-way automatic adjustment device for the brake pad gap adopts a double-nut cone clutch structure, which is simple in structure and has good versatility of accessories. The body adopts a convex structure and is formed by integral spinning, which can not only ensure the airtightness of the cylinder body but also realize the installation of the unit brake cylinder in the middle. The invention has complete functions and compact structure, and can meet the requirements of fast truck loading.

Description

technical field [0001] The invention relates to the technical field of rapid railway freight car braking, in particular to a unit brake cylinder with a hand brake device. Background technique [0002] At present, the running speed of domestic railway freight cars is below 120km / h. Therefore, the braking system adopts tread braking. [0003] With the rise of e-commerce in recent years, the market presents an urgent demand for railway wagons with a speed of 160km / h and above. As the speed of trucks increases, the braking power will increase quadratically when the braking distance is constant. The braking capacity of the traditional one-side tread where the brake shoes are in contact with the wheels is restricted by thermal stress and cannot meet the requirements of the above-mentioned speed vehicles. parking request. For this reason, disc brakes are required on fast railway wagons. Instead of the traditional friction brake between the brake shoe and the tread, the disc brake...
