[0022] see figure 1 and figure 2 It is a structural schematic diagram of the hand brake of the present invention. Such as figure 1 and figure 2 As shown, the hand brake includes a base component 1 installed on the car body, a driving shaft component fixed at one end on the base component 1, a sprocket component 21 of a transmission chain, a handle component, a hand wheel component and a box shell component. 2. Wherein, the box shell composition 2 is located at the front part of the hand wheel composition 21 and the winding chain wheel composition, which protects the internal structure of the hand brake, and supports the drive shaft composition and the winding chain wheel composition together with the base composition 1. The casing component 2 is fixed to the base component 1 by rivets, and the casing component 2 is provided with mounting holes for installing the handle 13 and the drive shaft 3 .

Abstract

The invention discloses a hand brake for railway heavy-duty trucks, which comprises a base, a driving shaft, a chain wheel, a hand wheel, a handle, and a box shell. The driving shaft includes a driving shaft, a ratchet, The pinion, the pinion shaft and the key wheel, the hand wheel are connected to the driving shaft, the driving shaft is connected to the ratchet, the key wheel and the pinion in turn, and the handle is composed of a handle, a horizontal shifting frame directly connected to the handle and an action with the horizontal shifting frame With the matching vertical dial frame, when the handle is rotated counterclockwise, the key wheel is dialed to disengage from the pinion. The advantage of the present invention is that the drive shaft of the handbrake is driven by the composition of the rotary handle and the handwheel to complete three functions, including the braking function, the quick relief function and the gradual relief function, which effectively improves the handbraking ability, and at the same time Improved the quick release performance characteristic of the handbrake brake.

Description

technical field [0001] The invention relates to the field of railway vehicle brake control, in particular to a hand brake for railway heavy-duty trucks. Background technique [0002] With the continuous improvement of the heavy load requirements of China's railway freight cars, the hand brake, as one of the important means for parking and preventing slippage, has higher and higher requirements for its hand brake capacity. In order to improve the hand brake rate under the premise of ensuring that the hand brake chain and the hand brake lever have sufficient safety margins, new trucks in my country have successively adopted additional levers and movable pulley structures. However, the adoption of additional levers and moving pulley structures simultaneously leads to an increase in the lifting height of the hand brake chain, which may lead to the overlapping of the chains on the winding shaft of the current hand brake and the reduction of the actual output force of the hand bra...
