A mobile mining machine includes a plurality of traction elements, a plurality of motors, a power source in electrical communication with the plurality of motors, and an energy storage system in electrical communication with the plurality of motors and the power source. Each of the motors is coupled to an associated one of the plurality of traction elements. Each of the motors is driven by the associated traction element in a first mode, and drives the associated traction element in a second mode. The energy storage system includes a shaft, a rotor secured to the shaft, a stator extending around the rotor, and a flywheel coupled to the shaft for rotation therewith. In the first mode, rotation of the motors causes rotation of the flywheel to store kinetic energy. In the second mode, rotation of the rotor and the flywheel discharges kinetic energy to drive the motors.

A warning triangle structure includes a base, a triangle, a number of connecting rods, and a braking device. The triangle includes a bottom end and a top end opposite the bottom end. The bottom end is fixedly mounted to the base. Each of the connecting rods includes a first end and a second end. The first end is fixedly coupled to the base, and the second end is mounted with a rotatable support wheel. The braking device is installed at the second end of at least one of the connecting rods. The braking device includes a transmission shaft coupled to the support wheel. The braking device controls the support wheel to stop rotating by stopping the transmission shaft from rotating.

A land vehicle includes a frame structure, a plurality of wheels, and an impact management system. The frame structure includes an operator cage that at least partially defines an operator cabin and a rear compartment positioned rearward of the operator cage in a longitudinal direction. The frame structure includes a pair of rails that each extends in the longitudinal direction from a first end arranged adjacent a pair of front wheels to a second end arranged adjacent a pair of rear wheels. The plurality of wheels are supported by the frame structure. The plurality of wheels includes the pair of front wheels and the pair of rear wheels. The pair of front wheels are positioned forward of the pair of rear wheels in the longitudinal direction.

A method for controlling an activation state of a braking-torque assistance system for reducing intake of braking energy in a service-brake system of a vehicle includes capturing and evaluating a plurality of demand indications for a startup of the braking-torque assistance system. If the evaluation of the captured plurality of demand indications reveals a demand for the startup of the braking-torque assistance system, a plurality of operating conditions of the service-brake system are captures and evaluated over a monitoring period. If, in turn, the evaluation of the captured plurality of operating conditions reveals that an overheating of the service-brake system is imminent, the braking-torque assistance system is actuated and one or more deactivation conditions of the braking-torque assistance system are checked. If the deactivation conditions are satisfied, the braking-torque assistance system is deactivated.

An emergency stop brake operation assembly necessary for a work vehicle when travelling autonomously in an unmanned state is provided in this brake system without introducing problems to manual driving of the work vehicle by an occupant. This brake system for work vehicles comprises: a brake pedal that is disposed in a driving section; a brake that brakes left and right rear wheels; a linkage mechanism that links the brake pedal and the brake in such a manner as to allow the brake pedal and the brake to operate in conjunction with each other; and an electric brake operating device that actuates the brake in response to an emergency stop command. The brake operating device has: an operation-receiving body that is coupled to the brake pedal; an electric actuator that operates the operation-receiving body; and a clearance-provided section which is located between the brake pedal and the electric actuator and allows displacement of the brake pedal and the linkage mechanism with respect to the electric actuator when the brake pedal is depressed.
