A type of ball and socket joint called a "torque ball" is used at one end of the torque tube to allow relative motion between the axle and transmission due to suspension travel. Later American Motors Rambler models (1962 through 1966) used a flange and cushion mount in place of the ball and socket. [5]
Other problems may be implicated in the case of older vehicles equipped with carburetors. Weak, disconnected, or mis-connected throttle return springs, worn shot-pump barrels, chafed bowden cable housings, and cables which jump their tracks in the throttle-body crank can all cause similar acceleration problems.
A typical ball joint with cutaway view (right) An inner tie rod end cut open to expose the ball joint. In an automobile, ball joints are spherical bearings that connect the control arms to the steering knuckles, and are used on virtually every automobile made. [1] They bionically resemble the ball-and-socket joints found in most tetrapod ...
Vehicles that commonly experience suspension loads heavier than normal, have heavy or hard springs, with a spring rate close to the upper limit for that vehicle's weight. This allows the vehicle to perform properly under a heavy load, when control is limited by the inertia of the load. Riding in an empty truck meant for carrying loads can be ...
The worm and sector was an older design, used for example in Willys and Chrysler vehicles, and the Ford Falcon (1960s). To reduce friction, the sector is replaced by a roller or rotating pins on the rocker shaft arm. Generally, older vehicles use the recirculating ball mechanism, and only newer vehicles use rack-and-pinion steering.
As the vehicle slowed down and engine speed decreased, the gearbox would shift back to low. However, the transmission was prone to sudden failure, due to the transmission being unable to withstand forces from the abrupt gear changes. The adoption of planetary gearsets was a significant advance towards the modern automatic transmission.
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 ...
A steering linkage is the part of an automotive steering system that connects to the front wheels. [1]The steering linkage which connects the steering gearbox to the front wheels consists of a number of rods.
