Abstract

The present invention discloses a manual brake using a double-geared driving mode, which comprises a box-shell assembly, a back-plate assembly, a main driving assembly, a sprocket assembly, a control mechanism and a speed reducing mechanism, wherein a middle shaft assembly is arranged between the main driving assembly and the sprocket assembly; a middle shaft of the middle shaft assembly is a hollow gear shaft; both ends of the middle shaft are fixed on a box shell and a back plate through bearings; a high-speed graded bull gear and a low-speed graded pinion are arranged on the middle shaft; the high-speed graded bull gear is engaged with a high-speed gear of the main driving assembly, and the low-speed graded pinion is engaged with a sprocket gear of the sprocket assembly; the sprocket assembly is fixed on the box shell and the back plate through the bearings; the sprocket gear of the sprocket assembly and a sprocket are arranged on the sprocket shaft at the same time; the sprocket is engaged with a braking chain; the control mechanism of the manual brake is arranged on the main driving assembly; the speed reducing mechanism is arranged on the back plate, and the speed reducing mechanism is connected with the middle shaft assembly.

Description

technical field [0001] The invention relates to a hand brake, in particular to a hand brake device for railway freight vehicles, especially a hand brake device for heavy-duty railway freight vehicles. Background technique [0002] With the development trend of railway heavy load, especially the successful development of freight wagons with an axle load of 40t, the original main type hand brake of general freight wagons can no longer meet the requirements. It is necessary to develop a hand brake with a larger output force to adapt to higher requirements. Contents of the invention [0003] The purpose of the present invention is to provide a hand brake with simple operation, low cost, reliable performance and high braking capacity. [0004] Technical solution of the present invention: in order to achieve this purpose, the hand brake designed in the present invention adopts a two-stage gear transmission method, including a case shell assembly, a back plate assembly, a main d...
