INTERNAL COMBUSTION LOCOMOTIVE CAB HAVING MULTISTAGE COLLISION PROTECTION FUNCTION
Document Type and Number:
WIPO Patent Application WO/2022/001387
Kind Code:
A1
Abstract:
An internal combustion locomotive cab having a multistage collision protection function, the internal combustion locomotive cab comprising a cab upper top cover (1), a cab lower fence (2), a vehicle body underframe (3) and a cab rear end wall (4), wherein the cab lower fence (2) is composed of a front end wall (5), a side wall (6) and a rear end wall (7), a buffer and energy absorption device I (8) is arranged at the front end of the vehicle body underframe (3), and a buffer and energy absorption device II (9) is arranged at the front end of the front end wall (5). The buffer and energy absorption devices are arranged at the front end of the vehicle body underframe and the lower portion of the front end of the cab, and the structure of the lower portion of the cab is designed as an integral frame structure, thereby constructing multistage safety protection measures for the internal combustion locomotive cab. The buffer and energy absorption devices are arranged at the front end of the vehicle body underframe and the lower portion of the front end of the cab in a relatively independent rectangular array manner, thereby giving full play to the protection effect of the buffer and energy absorption devices on the structure of the cab in a collision process, and fully utilizing locomotive space.
