Canada has a system of analogous rules called the Canada Motor Vehicle Safety Standards (CMVSS), which overlap substantially but not completely in content and structure with the FMVSS. The FMVSS/CMVSS requirements differ significantly from the international UN requirements, so private import of foreign vehicles not originally manufactured to ...
Lower ball joints are sometimes larger and may wear out faster, because the fore and aft loads, primarily due to braking, are higher at the bottom ball joint. (Torque reaction and drag add at the bottom joint, and partly cancel at the top joint.) Also, lateral cornering loads are higher at the bottom joint. Depending on the suspension design ...
Systematic motor-vehicle safety efforts began during the 1960s. In 1960, unintentional injuries caused 93,803 deaths; [5] 41% were associated with motor-vehicle crashes. In 1966, after Congress and the general public had become thoroughly horrified by five years of skyrocketing motor-vehicle-related fatality rates, the enactment of the Highway Safety Act created the National Highway Safety ...
When it was initially published in 1968, [10] Motor Vehicle Safety Standard No. 108 was part of 49 CFR 371.21, incorporating several SAE recommended practices by reference. [11] The 1969 version of FMVSS 108 allowed the use of two headlamps, each 7 in (180 mm) in diameter, or four smaller 5 + 3 ⁄ 4 in (150 mm) headlamps. [11]: Table I
The terms "active" and "passive" are simple but important terms in the world of automotive safety. "Active safety" is used to refer to technology assisting in the prevention of a crash and "passive safety" to components of the vehicle (primarily airbags, seatbelts and the physical structure of the vehicle) that help to protect occupants during a crash.
Suspension is the system of tires, tire air, springs, shock absorbers and linkages that connects a vehicle to its wheels and allows relative motion between the two. [1] Suspension systems must support both road holding/handling and ride quality, [2] which are at odds with each other. The tuning of suspensions involves finding the right compromise.
General Motors (GM) was founded in September of 1908. On June 1, 2009, at 8 a.m. -- almost 101 years later -- it ceased to exist, and control was handed over to turnaround executive Al Koch ...
In the latter case, the suspension can be called a multi-link, or dual-ball joint suspension. The four-bar linkage mechanism formed by the unequal arm lengths causes a change in the camber of the vehicle as it rolls, which helps to keep the contact patch square on the ground, increasing the ultimate cornering capacity of the vehicle. It also ...
