A system for transferring torque with zero lash from a driver to a driven object is provided. The system includes a shaft disposed about a rotational axis and a hub defining a bore that receives the shaft. The shaft and hub are each configured for coupling to one of the driver and driven object. The shaft defines a flat on a radially outer surface and the hub defines a flat on a radially inner surface opposing the flat in the shaft. In one embodiment, the shaft includes a threaded bore and the hub includes an aligned through bore. Rotation of a threaded fastener in the bores draws the flat into engagement. In another embodiment, the hub includes a threaded through bore. Rotation of a fastener extending through the bore and engaging the shaft diametrically opposite the flats urges the flats into engagement.

A braking assembly includes a depressible brake pedal. The brake pedal remains in a neutral position when not depressed. A link arm is mechanically linked with the brake pedal. The link arm moves as a function of a position of the brake pedal. A bell crank is mechanically linked with the link arm. The bell crank moves as a function of a position of the link arm. A stop member moves with the bell crank. The stop member abuts against the link arm to prevent the brake pedal from over-travelling beyond a predetermined distance past the neutral position after the depressed brake pedal is released.

A fluid sensor assembly is provided for sensing a fluid property in-line. The assembly includes a body with a port for connecting the body to a fluid line and internal passage connecting the first port to a second port. The assembly also includes a sensor interface portion attached to the body and a fluid sensor that interfaces with the sensor interface portion. The fluid sensor includes a sensing element that communicates with the internal passage via the second port. The sensor and the body are fixably attached by an attaching portion to form a single, integrated part.

A mechanism is provided for actuating a switch that transmits motion from a first component, which moves along a first path, to a system that is attached to the mechanism. The mechanism includes a second component that moves transverse to the first path and a third component having a switch actuating portion, wherein movement of the first component causes the third component to actuate the switch using motion that is generally along the first path.

Switch actuation method and mechanism

An electronically controlled fluid pressure braking system for a heavy duty vehicle includes an operator controlled mechanism which generates independent brake pressure command signals, each of which are transmitted to separate auxiliary controllers. Each of the controllers transmits its command signal to the other auxiliary controllers and also to a master control unit. The master control unit sorts between the command signals and generates a preliminary brake pressure request signal which is transmitted back to each of the auxiliary controllers. Each of the auxiliary controllers then examines the brake pressure request signal received from the master controller and actuates the corresponding vehicle brakes if the pressure request signal is within normal limits. If the signal is not within normal limits, each of the auxiliary controllers is capable of generating a brake pressure request signal independently of the master control unit.
