A combined cooling and water braking system for a vehicle comprises a first water recirculation loop having a first heat exchanger configured to cool water flowing in the first water recirculation loop, the first water recirculation loop comprising a water conduit for transporting heat away from a propulsion device configured to generate a propulsion power for the vehicle. A second water recirculation loop having a second heat exchanger is configured to cool water flowing in the second water recirculation loop. A retarder is configured to be coupled to a pair of wheels of the vehicle. The second water recirculation loop may be selectively used for cooling the propulsion device and for providing water to the retarder for water braking. There is also provided a method for cooling a propulsion device of a vehicle and water braking a pair of wheels of a vehicle.

A brake booster for a brake system of a vehicle, having a first input piston component, and a valve body. The brake booster has a second input piston component, which is pushed away from the first input piston component in the braking direction using a compression spring, and a locking mechanism is embodied such that when the differential travel between the booster travel and the input travel is smaller than a predefined first limit value, the second input piston component is adjustable using the compression spring together with the valve body away from the first input piston component, and when the differential travel exceeds the first limit differential travel, the second input piston component is locked in place on the first input piston component.

A main ECU controls a braking force by driving an electric motor of a brake mechanism based on a value detected by a thrust force sensor provided to the brake mechanism. The main ECU calibrates (corrects) the value detected by the thrust force sensor based on a driving force acquired when, while a driving force is applied to left and right front wheels serving as driving wheels with the braking force applied to a rear right wheel or a rear left wheel by the brake mechanism, this driving force exceeds the braking force.

A hydraulic braking arrangement for controlling front and rear brakes of an off-road vehicle, includes a power brake valve fluidly interposed between rear brakes and a first source of fluid in pressure of vehicle. The power brake valve is configured to selectively allow passage of fluid coming from first source to rear brakes. The power brake valve is further configured to provide at least a hydraulic signal configured to control a relay valve fluidly interposed between front brakes and a second source of fluid in pressure of the vehicle and being configured to selectively allow passage of fluid coming from second source to front brakes in function of the at least one hydraulic signal.

A method and mechanism for initiating an emergency stop for an unattended railcar is disclosed. The method may include using a trip arm placed alongside the railway tracks at a designated stop point that may contact a portable trip-cock lever arm that extends out beyond the perimeter of the railcar if the railcar reaches the stop point as it moves along the track. The trip-cock lever arm may be attached to a valve that is connected to the pneumatic brake system of the unattended railcar. As the trip-cock lever arm rotates, the valve may open to release the air pressure in the pneumatic brake system causing the brakes to engage the wheels causing the railcar to stop.

The present disclosure relates to shipping and storage containers. Specifically, the present disclosure relates to shipping and storage containers, which are traditionally stationary, converted to easily-portable containers. More specifically, the portable containers include a deployable/retractable landing/moving apparatus, a removable tow bar assembly, and leveling support systems. The portable containers can have many uses including as temporary to permanent housing, office space, and school rooms, or to house equipment for use in mobile telecommunication networks and systems, including cellular towers that can be set-up in both permanent and temporary locations.

A threaded nut of a ball-screw for a brake booster is constructed as a hydraulic piston and is produced from the group of martensitically hardening steels which are non-corroding with respect to brake fluid and which has in percent by weight: between 0.4% and 1.3% carbon (C), up to 2% silicon (Si), up to 2% manganese (Mn), between 12% and 20% chromium (Cr), and phosphorus (P) and sulphur (S) together at less than 0.015%, the balance being iron and, where applicable, melting-related impurities. Addition of the following materials to the above-described steel may be advantageous: up to 2% molybdenum (Mo), up to 0.2% vanadium (V), and up to 3% nickel (Ni).
