Abstract
This is a new brake system for minimizing the turning radius of a vehicle when it makes a U-turn or parks. The minimum turning radius of a conventional vehicle has a certain limit because a conventional vehicle takes the Ackerman-Jeantaud steering principle. The object of this invention is to overcome the limit of the minimum turning radius by introducing the new concept, the one wheel brake system. This invention utilizes the phenomenon that if one wheel is braked, the other wheel is driven by the differential gear. Hence the vehicle circles around a braked wheel as its pivot. So it turns much smaller than the minimum turning radius of the Ackerman-Jeantaud steering angle.
Claims13
A one-wheel brake system for a vehicle comprising:
- a brake pedal;
- a booster for boosting a brake force transmitted from the brake pedal via a push rod;
- a master cylinder for receiving the boosted brake force from the booster, thereby generating a hydraulic brake pressure;
- and
- a brake unit for selectively transmitting the hydraulic brake pressure generated from the master cylinder to at least one wheel of the vehicle via a brake fluid line, so that the at least one wheel of the vehicle is braked, wherein the brake unit comprises:
- an actuator for operating the push rod upon receiving power;
- fluid line cut-off units each adapted to cut off a brake fluid line directly connected to an associated one of the wheels upon receiving power;
- and
- an electronic circuit for controlling supply of the power to the fluid line cut-off units and the actuator.

- and
- the brake unit comprises:
- a pair of actuators for generating a hydraulic brake pressure in the first brake fluid line upon receiving a power, and transmitting the generated hydraulic brake pressure only to the second brake fluid lines,
- fluid line cut-off units each adapted to cut off an associated one of the second brake fluid lines upon receiving power;
- and
- an electronic circuit for controlling supply of the power to the fluid line cut-off units and the actuators.
