BRAKING SYSTEM FOR AN AT LEAST TWO-AXLE VEHICLE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18257068 titled 'BRAKING SYSTEM FOR AN AT LEAST TWO-AXLE VEHICLE

Simplified Explanation

The braking system described in the patent application is designed for a vehicle with at least two axles. It consists of a front axle unit and a rear axle unit, which are hydraulically separate from each other.

The front axle unit includes a first motorized brake pressure buildup device, a front-wheel wheel-brake cylinder that can be mounted on the first front wheel, and a second front-wheel wheel-brake cylinder that can be mounted on the second front wheel.

The rear axle unit includes a second motorized brake pressure buildup device, a first rear-wheel wheel-brake cylinder that can be mounted on the first rear wheel, and a second rear-wheel wheel-brake cylinder that can be mounted on the second rear wheel. The second motorized brake pressure buildup device is connected to the first rear-wheel wheel-brake cylinder through a first rear-axle hydraulic path and to the second rear-wheel wheel-brake cylinder through a second rear-axle hydraulic path.

There is a first separating valve in the first rear-axle hydraulic path and/or a second separating valve in the second rear-axle hydraulic path.

  • The braking system is designed for a vehicle with at least two axles.
  • It includes separate front and rear axle units.
  • The front axle unit has a motorized brake pressure buildup device and wheel-brake cylinders for each front wheel.
  • The rear axle unit also has a motorized brake pressure buildup device and wheel-brake cylinders for each rear wheel.
  • The rear axle unit is hydraulically separate from the front axle unit.
  • The rear axle unit is connected to the front axle unit through separate hydraulic paths.
  • The hydraulic paths are equipped with separating valves.

Potential applications of this technology:

  • Automotive industry: This braking system can be used in various types of vehicles, such as cars, trucks, and buses.
  • Off-road vehicles: The separate front and rear axle units can provide improved braking performance and control in off-road conditions.
  • Racing vehicles: The precise control and independent operation of the front and rear brakes can be beneficial in racing applications.

Problems solved by this technology:

  • Improved braking performance: The separate axle units and motorized brake pressure buildup devices allow for more precise and efficient braking.
  • Enhanced control: The ability to independently control the front and rear brakes can improve stability and maneuverability.
  • Safety: The hydraulic separation and separating valves provide redundancy and fail-safe mechanisms in case of brake system failures.

Benefits of this technology:

  • Improved braking efficiency: The motorized brake pressure buildup devices ensure quick and consistent brake pressure, resulting in better overall braking performance.
  • Enhanced stability and control: The independent operation of the front and rear brakes allows for better distribution of braking force, improving stability and control during braking.
  • Redundancy and safety: The hydraulic separation and separating valves provide backup systems and fail-safe mechanisms, enhancing the safety of the braking system.


Original Abstract Submitted

A braking system for an at least two-axle vehicle. The braking system includes: a front axle unit including a first motorized brake pressure buildup device, a front-wheel wheel-brake cylinder mountable at a first front wheel, and a second front-wheel wheel-brake cylinder mountable at a second front wheel; and a rear axle unit hydraulically separate from the front axle unit, including a second motorized brake pressure buildup device, a first rear-wheel wheel-brake cylinder mountable at a first rear wheel, and a second rear-wheel wheel-brake cylinder mountable at a second rear wheel. The second motorized brake pressure buildup device is hydraulically connected via a first rear-axle hydraulic path at the first rear-wheel wheel-brake cylinder and via a second rear-axle hydraulic path at the second rear-wheel wheel-brake cylinder. A first separating valve is situated in the first rear-axle hydraulic path and/or a second separating valve is situated in the second rear-axle hydraulic path.
