Utah Used Trucks Terms and Definitions

Trailer Tongue Weight The downward force exerted on the hitch ball by the trailer coupler. In most cases, it should not be less than 10 percent of the trailer load or more than 15 percent. Brake Shoe The nonrotating portion of a tread or disc brake assembly. The shoe is pressed against the tread disc or drum when the brake is applied. King Pin The main fastening member between a fifth-wheel hitch and trailer. Weight-Distributing Hitch A weight-distributing system includes a receiver attached to the tow vehicle, plus a removable hitch head and spring bar assembly that fits into the receiver opening and hook up brackets that connect the spring bars to the trailer frame. Light Truck Trucks of 10000 pounds gross vehicle weight rating or less including pickups vans and sport utility vehicles. Acceleration Power Measured in kilowatts. Pulse power obtainable from a battery used to accelerate a vehicle. This is based on a constant current pulse for 30 seconds at no less than 2/3 of the maximum open-circuit-voltage at 80% depth-of-discharge relative to the battery's rated capacity and at 20 degrees Celsius ambient temperature. Carburetor See also Diesel Fuel System Fuel Injection A fuel delivery device for producing a proper mixture of gasoline vapor and air and delivering it to the intake manifold of an internal combustion engine. Gasoline is gravity fed from a reservoir bowl into a throttle bore where it is allowed to evaporate into the stream of air being inducted by the engine. The fuel efficiency of carburetors is more temperature dependent than fuel injection systems. Fifth-Wheel Trailer One in which the tongue of the trailer attaches to a specially designed hitch mounted in the bed of a pickup truck. It is most popular with large travel, moving, and horse trailers. Air Brake A brake in which the mechanism is actuated by manipulation of air pressure. The term is often used to describe brakes that employ air under pressure above atmospheric in contrast to vacuum brakes which employ pressure below atmospheric. V-Bridles Bridles are made of certified 2-Ply heavy polyester web. V-Bridles are available with J-hooks, TJ&R hooks, T-hooks, or axle hooks more for cars, sports cars, SUV’s, and pickup trucks.
