You’re stuck in traffic on an August afternoon and your auto air conditioning system is not up to the task. Sweat pours from your neck and runs down your back, turning your seat into a swamp of discomfort. Your legs feel like they’re stuck to the vinyl or grated by cheap velvet. Your hands are ready to slip from the steering wheel, and you’re glad that your eyebrows are keeping the sweat from getting into your eyes.
Rack & Pinion steering is steadily becoming the typical kind of steering on cars, small trucks, and SUVs. It is actually a pretty simple mechanism. A rack and pinion gearset is encircled in a metal tube, with each end of the rack poking out from the tube. A rod, called a tie rod, hooks up to each end of the rack.
As the vanes turn, they draw hydraulic fluid from the return line at low pressure and push it into the outlet at high pressure. The amount of flow from the pump often varies based on the engine’s speed. The pump is designed to send a regular flow when the engine is idling. But when engine is running at higher speeds, the pump moves much more fluid than necessary.
You can expect to see innovations that will drastically improve fuel efficiency. One of the coolest ideas being considered iin the future of power steering is a “steer-by-wire” or “drive-by-wire” system. These would take out the mechanical link between the steering wheel and the steering, using a purely electronic control system instead. Basically, the steering wheel would operate like the one you buy for your video games or computer. They all contain sensors which tell the vehicle what the driver is doing with the wheel, and most contain some motors in them to give the driver feedback on what the car is doing. The output of these sensors would control the motorized steering system. This would free up more space in the engine area and reduce vibrations by eliminating the steering shaft.
The recirculating-ball steering gear has a worm gear. It helps to think of the gear in two parts. The first part is a metal block with a threaded hole in it. This block has gear teeth cut into the exterior, and these engage a gear that moves the pitman arm (see diagram above). The steering wheel connects to a threaded rod, much like a bolt, that fits into the hole in the block. When the steering wheel turns, it rotates the bolt. Instead of twisting further into the block the way a normal bolt would, this bolt is held fixed so that when it turns, it moves the metal block, which then goes on to move the gear that orients the wheels.
Shocks and struts are two important parts of your suspension system that ensure your vehicle is balanced and riding comfortably with all four wheels on the road. We highly encourage you to get suspension inspection in order to maintain excellent car handling. Blown shocks and struts can result in a vehicle that handles poorly or even unsafely on public roads. Upon inspection, our experienced tire and auto service professionals will repair or replace those worn suspension parts, so your car will drive just like it did that first day.
The coil springs in your suspension system, along with your struts and shocks, all work to reduce road impact, spread the weight of your vehicle, and keep all four of your wheels in contact with the ground. How tightly would the springs are and the rigidity of the suspension springs can also have an impact on your vehicle’s handling and performance.
To put it simply, it is the transmission’s job to turn the engine’s power (RPMs) into torque for the wheels of the vehicle. For example, 1st gear is the shortest gear and as you work your way up to 2nd, 3rd, and 4th gear, the gear ratios become taller. This permits your vehicle to climb to higher speeds as the gears get taller. When your vehicle is accelerating, gear selection is crucial to maximize the torque going to the wheels.
