Abstract:
A powered vehicle includes a spring-applied hydraulic release (SAHR) vehicle brake comprising first and second mutually engageable brake elements. The first brake element is secured to or forms part of a rotatable element of the drive train of the vehicle and the second is non-rotatably moveably mounted on the vehicle such that the first and second elements are mutually engageable with and separable from one another. Mutual engagement of the brake elements causes braking of rotation of the rotatable element. The SAHR vehicle brake includes (i) a resiliently deformable member acting on the second brake element so as to urge the first and second brake elements into mutual engagement and (ii) a hydraulic control circuit for applying hydraulic pressure to the second brake element so as to oppose the action of the resiliently deformable member and thereby normally maintain the first and second brake elements separated from one another.

Claim (Index 16):
A powered vehicle comprising:\n a spring-applied hydraulic release (SAHR) vehicle brake comprising:\n a first brake element that is secured to or forms part of a rotatable element of a drive train of the vehicle; \n a second brake element that is non-rotatably moveably mounted on the vehicle such that the first and second brake elements are mutually engageable with and separable from one another, where such mutual engagement of the brake elements causes braking of rotation of the rotatable element; \n a resiliently deformable member acting on the second brake element so as to urge the first and second brake elements into mutual engagement; and \n a hydraulic control circuit configured to apply hydraulic pressure to the second brake element so as to oppose the action of the resiliently deformable member and thereby maintain the first and second brake elements separated from one another; \n a non-electric fail-safe comprising a hydraulic release valve that is configured to be alterable between a one-way valve configuration effective when a driving mode of the vehicle is selected and that permits the application of pressure to the second brake element and prevents venting thereof; and a pressure relief configuration configured to provide two-way flow of hydraulic fluid via the hydraulic release valve, wherein the hydraulic release valve including a biasser biasing the hydraulic release valve to the one-way valve configuration.
