Background
With the increasing load of the railway freight car, the requirement for the hand braking parking capacity is also improved. The hand brake is a mechanism which is arranged on a vehicle brake device and takes manpower as a brake motive power to realize braking and parking. The hand brake is mainly connected with a basic brake device of the railway wagon through a chain. When the railway wagon is shunting or the wagon is parked, the manual brake is operated by taking manpower as the brake prime power. The hand brake machine generates a braking force, and the braking force is transmitted to the brake shoes of the basic brake device through the chain, so that the brake shoes are attached to the wheels to generate a braking action.
During operation, the hand brake chain is typically connected to the truck integrated brake hand brake lever, or the front brake lever that is braked by the lever. One end of the chain is fixed on the chain winding shaft through the pin, the chain is wound on the chain winding shaft through the rotation motion to be stacked, the pulling force is generated along the chain, and the pulling force is transmitted to the basic braking device through the other end of the chain, so that the braking is carried out.
However, when the chains are stacked on the spool, a high demand is placed on the hand braking force. If the braking force is not enough, the vehicle slipping accident can occur. To solve the problem of insufficient hand braking force, one typically amplifies the braking force by adding a lever. This creates new problems: when the braking force is amplified, the winding amount of the chain of the hand brake is too large, the number of layers stacked on the winding shaft is too large, and the output efficiency of the hand brake is offset; on the other hand, the application of the labor-saving lever can occupy more vehicle body space, and is difficult to implement in some special vehicle body environments.
