3.6 Braking system
The equipment braking system consists of two independent systems, one for railway and one for road. When the railway or road machine is running alone, hydraulic caliper disc brakes are used, and foot-controlled braking is used; when towing rail vehicles , brake shoes acting on the train wheels are used for braking.
3.6.1 Single-machine braking is achieved by stepping on the brake pedal, and the pressurized air enters the booster pump through the master cylinder. After the booster pump injects the pressurized oil into the drive axle, the brake is achieved through the caliper disc brake; when the brake pedal is released, the pressurized air of the booster pump is discharged through the brake valve, the pressure of the booster pump disappears, and the equipment is relieved. There are four caliper disc brakes, located at both ends of the front drive axle and the rear drive axle. The parking brake is located at one end of the gearbox output shaft.
3.6.2 Automatic brake control devices are generally used for train braking. They have two functions: normal braking and emergency braking. They can realize normal braking and emergency braking of trains. Normal braking controls the braking, pressure maintenance and relief of the brakes of each vehicle in the train by moving the control valve handle to the corresponding position. The equipment is equipped with a screw air compressor to provide sufficient compressed air for train traction. The compressed air is mainly used for the relief of the towed train, that is, to inflate the train brake cylinder through the QQ2 brake valve. When the pressure reaches 0.6MPa, the train brake is released and the tractor can tow the vehicle to move. Emergency braking is to turn the emergency exhaust valve to the emergency braking position, which can directly connect the train pipe to the atmosphere, rapidly reduce the pressure of the train pipe, and trigger the brakes of each vehicle in the train to implement emergency braking.

(QQ2 brake)
3.6.3 An emergency brake button is installed on one side of the vehicle body. When an unexpected situation occurs, people outside the vehicle can touch the emergency brake button to shut down the engine in an emergency, ensuring the safety of vehicle operation.
3.6.4 A screw air compressor is used, and the air compressor meets the requirements of maximum exhaust pressure not less than 0.8MPa and air pumping speed not less than 2.0m³/min, and can provide the compressed air required for both railway and highway working conditions.
3.7 Electrical System
The electrical wiring of the equipment is invisible, single-wire, DC24V, and each major electrical appliance is equipped with a fuse to achieve overcurrent protection. The wires must be protected by casing, the wiring is reasonable, and the appearance is beautiful. The starting battery uses two 12V maintenance-free lead-acid batteries, which are well-known brand products, and the capacity of a single battery is not less than 120Ah.
The vehicle body is equipped with no less than two lights at the front and rear, and the luminous intensity of each light complies with the provisions of GB/T20418-2011. LED lights are preferred, including front and rear working lights, lighting lights, warning lights and side lights, etc., to meet the requirements of night operation of the equipment.

The steel wheel has a diameter of 500mm and a large contact surface with the inner and outer sides of the rail, which increases the stability of operation and the anti-drop performance, improving safety.
The steel wheel guide device uses a hydraulic lifting cylinder to lift the guide wheel and complete the road-rail conversion. The hydraulic lifting cylinder is equipped with a pull-wire displacement sensor to achieve the positioning of the guide wheel.
The intermediate locking device is used to manually close the intermediate connecting rod after the equipment has completed the on-road operation by turning the steering wheel when the alignment indicator light comes on, thus completing the conversion from road to rail.
The hydraulic system has a self-locking function. The hydraulic cylinder for lifting the guide wheel and the hydraulic cylinder for intermediate locking are equipped with a two-way hydraulic lock to prevent the guide device or the intermediate locking device from failing due to oil leakage, rupture, etc. caused by force majeure factors in the hydraulic pipeline.
