The Design Of Tight-Lock Coupler And Buffer For The City Truck Traffic

Developing the city truck traffic system has become the main route to solve the problem of city traffic. The tight-lock coupler and buffer is one of basic parts of city truck. It links every vehicle of the train and transfer pull force or impulsive force at the running and translate task of train.In order to satisfy the requirement of city truck, systems analysis has been taken for the tight-lock coupler and buffer .The coupler body was taken optimal design. The semiautomatic tight-lock coupler adopted spring set for manual separate lock and replacement .The semiforever traction rod fix buffer and unfix buffer adopted long round whole structure. The casting parts include coupler body, fixing seat, semiautomatic coupler bracket and semiforever bracket have carried into execution with casting technologic designed and simulative concreting analysis. The elastic rubber mud buffer has the characteristic of more capability, less impedance force, high absorb rate. The high pressure and hermetical structure ensure the hermetic capability and the running life. The tight-lock coupler and buffer was passed the join test, join range test, pull force of join test and air hermetic capability test on the special test equipment. The main parts was passed static state test on normal temperature and low temperature, the capability test, the endure test, the firmly test and tiredness test.The item has been passed the CSR technology examination.
