Abstract: The fifth wheel of an articulated vehicle comprising the coupling between a semi-trailer and a tractor is provided with measuring apparatus for measuring forces imparted from the semi-trailer. The apparatus comprises a sensing device for measuring horizontal loads, and a sensing device for measuring vertical loads. The signals from the sensing devices and are fed into an electronic controller, in turn to cause the brakes on the trailer to be applied to achieve balanced braking, anti-lock control, and traction control of the wheels. A tractor fitted with a braking system of the brake-by-wire type with a conventional semi-trailer, without modifications to semi-trailer or to the braking components of the semi-trailer can therefore be used.

Abstract: A brake actuator has a body containing a pair of brake-applying members which may be actuated hydraulically to separate the friction elements of a brake into engagement with a rotatable braking surface. The members are interconnected by a mechanism in the form of a shaft of which respective end portions are provided with reversible threaded portions of opposite hand which engage corresponding threads within the members, the shaft being constrained against axial movement between bearings. Any excess movement of one of the members relative to the other is transmitted to that other member such as to cause an opposite and proportional force on the other member to substantially equalize the wear rates on the friction elements.

Abstract translation: 制动致动器具有容纳一对制动施加构件的主体，所述制动施加构件可被液压地致动以将制动器的摩擦元件分离成与可旋转的制动表面接合。 这些构件通过轴的形式相互连接，其相应的端部设置有相对的手的可逆螺纹部分，其接合构件内的相应的螺纹，轴被限制在轴承之间的轴向运动。 一个构件相对于另一个构件的任何多余的运动被传递到该另一个构件，以便对另一个构件产生相反且成比例的力，以使摩擦元件上的磨损率基本相等。
