Wheel alignment, which is sometimes referred to as breaking or tracking, is part of standard automobile maintenance that consists of adjusting the angles of wheels to the car manufacturer specifications. [1] The purpose of these adjustments is to reduce tire wear and to ensure that vehicle travel is straight and true (without "pulling" to one ...
Ladder frame pickup truck chassis holds the vehicle's engine, drivetrain, suspension, and wheels The unibody - for the unitized body - is also a form of a frame. A vehicle frame, also historically known as its chassis, is the main supporting structure of a motor vehicle to which all other components are attached, comparable to the skeleton of an organism.
As part of the automotive restoration process, repair of the car's frame is important since it serves as the foundation for the entire car. The frame should be inspected for straightness, twisting, alignment, rust damage, stress fractures, collision damage and condition of the mounting points for the body, suspension, and other components.
The centerbore of a wheel is the hole in the center of the wheel that centers it over the mounting hub of the car. Some factory wheels have a centerbore that matches exactly with the hub to reduce vibration by keeping the wheel centered. Wheels with the correct centerbore for the car they will be mounted on are known as hubcentric.
Research by Car and Driver conducted using a selection of differently sized alloy wheels from 16 to 19 in (41 to 48 cm) all outfitted with the same make and model of tires showed that both acceleration and fuel economy suffered with larger wheels. [3] They also noted that ride comfort and noise were negatively affected by the larger wheels.
Thus, in a car with a short wheelbase ("SWB"), the short lever arm from the CM to the rear wheel will result in a greater lateral force on the rear tire which means greater acceleration and less time for the driver to adjust and prevent a spin out or worse. Wheelbases provide the basis for one of the most common vehicle size class systems.
The BMW i3 electric car is one of the rare modern passenger cars with a separate body and frame design (2013). Body-on-frame is a traditional motor vehicle construction method whereby a separate body or coach is mounted on a strong and relatively rigid vehicle frame or chassis that carries the powertrain (the engine and drivetrain ) and to ...
The CTC-2 chassis of an RCA CT-100 television. A chassis (US: / ˈ tʃ æ s i /, [1] UK: / ˈ ʃ æ s i /; [2] plural chassis /-i z / from French châssis) is the load-bearing framework of a manufactured object, which structurally supports the object in its construction and function.
