Specific embodiment
The utility model is described further below in conjunction with attached drawing:
Embodiment 1: a kind of freight car braking failure forced brake device, referring to Fig.1 shown in -3, including control processor, biography
Sensor 3, hydraulic control system and braking rubber block 4；The hydraulic control system includes hydraulic oil container 5, hydraulic pump 8, check valve
7, three-position four-way valve 6, overflow valve 9, hydraulic cylinder 1；The hydraulic cylinder 1 is mounted on front and back axle at wheel；The hydraulic oil
Case 5, hydraulic pump 8, check valve 7, three-position four-way valve 6 and overflow valve 9 are installed at the center of front and back axle, and pass through fluid pressure line
It is connected；The sensor 3 is arranged on hydraulic cylinder mandril 2；The braking rubber block 4 is mounted at the end of hydraulic cylinder mandril 2；
The control processor is located inside truck cab, and is in be electrically connected with sensor 3；The control processor uses single-chip microcontroller
Control system.The number of the sensor 3, hydraulic control system and braking rubber block 4 is respectively 4.
Specifically, the sensor can be circular plate type load cell, embedded in hydraulic cylinder mandril and braking rubber block it
