18 wheeler accident lawyer Reshard Alexander is dedicated to holding professional truck drivers and trucking companies accountable for their negligence.

There are an estimated 500,000 truck accidents in the U.S. each year. Nearly 5,000 of these result in fatalities. The remainder often results in injuries of varying degrees. With four major interstates running through Houston — I-45, I-10, US-290, and I-69 — Texans see more than their fair share of trucking accidents. Unfortunately, many of these accidents are caused by the negligence of truck drivers or trucking companies.

A lot of professional truck drivers work for big motor carrier companies who have law firms ready to fight the moment a driver is involved in a truck wreck. It isn’t unusual for a representative (safety director) of their company to arrive on the scene of an accident to solicit signatures from the injured parties to decrease their liability. If you’re involved in an accident with a large truck, then it is important to keep in mind that you shouldn’t sign anything placed in front of you from the professional driver, the driver’s employer or the insurer of the driver. In the event that you or a loved one was hurt in a collision between a large truck, you want an experienced truck accident attorney that will fight for you.

18 wheeler accident lawyer Reshard Alexander understands exactly what it takes to fight the legal teams of big trucking firms. I help families and their loved ones in a dire time of need. Time is of the essence in these kinds of cases, therefore it is important to call a lawyer versed in this area of law immediately.  It is best to consult an experienced Houston truck accident attorney to get help in seeking the claim.

Overview

In automobiles and other wheeled vehicles, the differential allows the outer drive wheel to rotate faster than the inner drive wheel during a turn. This is necessary when the vehicle turns, making the wheel that is traveling around the outside of the turning curve roll farther and faster than the other. The average of the rotational speed of the two driving wheels equals the input rotational speed of the drive shaft. An increase in the speed of one wheel is balanced by a decrease in the speed of the other.

When used in this way, a differential couples the longitudinal input propeller shaft to the pinion, which in turn drives the transverse ring gear of the differential. This also usually works as reduction gearing. On rear wheel drive vehicles the differential may connect to half-shafts inside an axle housing, or drive shafts that connect to the rear driving wheels. Front wheel drive vehicles tend to have the engine crankshaft and the gearbox shafts transverse, and with the pinion on the end of the counter-shaft of the gearbox and the differential enclosed in the same housing as the gearbox. There are individual drive-shafts to each wheel. A differential consists of one input (the drive shaft) and two outputs, which are connected to the two drive wheels; however the rotation of the drive wheels are coupled to each other by their connection to the roadway. Under normal conditions, with small tyre slip, the ratio of the speeds of the two driving wheels is defined by the ratio of the radii of the paths around which the two wheels are rolling, which in turn is determined by the track-width of the vehicle (the distance between the driving wheels) and the radius of the turn.

Application to vehicles

When cornering, the inner wheel travels a shorter distance than the outer wheel, so without a differential either the inner wheel rotates too quickly or the outer wheel rotates too slowly, which results in difficult and unpredictable handling, damage to tires and roads, and strain on (or possible failure of) the drivetrain.

In rear-wheel drive automobiles the central drive shaft (or prop shaft) engages the differential through a hypoid gear (ring and pinion). The ring gear is mounted on the carrier of the planetary chain that forms the differential. This hypoid gear is a bevel gear that changes the direction of the drive rotation.

Loss of traction

One undesirable side effect of an open differential is that it can limit traction under less than ideal conditions. The amount of traction required to propel the vehicle at any given moment depends on the load at that instant—how heavy the vehicle is, how much drag and friction there is, the gradient of the road, the vehicle’s momentum, and so on.

The torque applied to each driving wheel is the result of the engine, transmission and drive axle applying a twisting force against the resistance of the traction at that roadwheel. In lower gears, and thus at lower speeds, and unless the load is exceptionally high, the drivetrain can supply as much torque as necessary, so the limiting factor becomes the traction under each wheel. It is therefore convenient to define traction as the amount of force that can be transmitted between the tire and the road surface before the wheel starts to slip. If the torque applied to one of the drive wheels exceeds the threshold of traction, then that wheel will spin, and thus provide torque only at the other driven wheel equal to the sliding friction at the slipping wheel. The reduced net traction may still be enough to propel the vehicle slowly.

An open (non-locking or otherwise traction-aided) differential always supplies close to equal torque to each side. To illustrate how this can limit torque applied to the driving wheels, imagine a simple rear-wheel drive vehicle, with one rear roadwheel on asphalt with good grip, and the other on a patch of slippery ice. It takes very little torque to spin the side on slippery ice, and because a differential splits torque equally to each side, the torque that is applied to the side that is on asphalt is limited to this amount.^[7][8]

Based on the load, gradient, etc., the vehicle requires a certain amount of torque applied to the drive wheels to move forward. Since an open differential limits total torque applied to both drive wheels to the amount used by the lower traction wheel multiplied by two, when one wheel is on a slippery surface, the total torque applied to the driving wheels may be lower than the minimum torque required for vehicle propulsion.^[9]

A proposed alternate way to distribute power to the wheels, is to use the concept of a gearless differential, about which a review has been reported by Provatidis,^[10] but the various configurations seem to correspond either to the “sliding pins and cams” type, such as the ZF B-70 available on early Volkswagens, or are a variation of the ball differential.

Many newer vehicles feature traction control, which partially mitigates the poor traction characteristics of an open differential by using the anti-lock braking system to limit or stop the slippage of the low traction wheel, increasing the torque that can be applied to the opposite wheel. While not as effective as a traction-aided differential, it is better than a simple mechanical open differential with no traction assistance.

Active differentials

A relatively new technology is the electronically controlled ‘active differential’. An electronic control unit (ECU) uses inputs from multiple sensors, including yaw rate, steering input angle, and lateral acceleration—and adjusts the distribution of torque to compensate for undesirable handling behaviors such as understeer.

Fully integrated active differentials are used on the Ferrari F430, Mitsubishi Lancer Evolution, Lexus RC F and GS F, and on the rear wheels in the Acura RL. A version manufactured by ZF is also being offered on the B8 chassis Audi S4 and Audi A4.^[11] The Volkswagen Golf GTI Mk7 in Performance trim also has an electronically controlled front-axle transverse differential lock, also known as VAQ.^[12]
