Liftovka SUVs

Keen on off-road people are divided into two types - those who are in a jeep, among other things, full-ride through the city, and who makes his other in a four-wheel drive sports cutlet. Lift - one of those procedures, which the former can afford to do without much damage to their usual ride, but instead we get a few extra inches of ground clearance. Liftovka There are two types: body lift (body) and suspension lift (suspension) with which the machine can be shod with wider tires than those offered by original equipment. To determine what kind of lift you need to do first, we calculated the size of the wheel, which will be optimally fit with the new size. To this end, it turns out the distance from the pad-bump to the place it firmly on the motor, added to it a couple of centimeters. Next, take measurements of the distances from the points of the wing-to-wheel (with the turning wheel). And measured the diameter of your own wheels, installed on the machine. It turns out that the maximum wheel size is the sum of the diameter of the wheels and the distance to the wing with a view of the suspension multiplied by two. In subsequent calculations of the upcoming tuning should be noted that the diameter of the wheels is limited to the future not only in size car, but engine power, transmission capacity - the jeep can not just pull a huge mud tires for off-road, anyway, that the child wear shoes adult and ask for a run . The meaning of the installation of large wheels can be lost due to lack of torque, so that professionals do not recommend increasing the size of the wheels more than 30%. Jeep should have enough power for the scroll wheel in a viscous substance, and a well trogatsya with the first and the second gear. If engine power is still lost, it can be corrected by replacing the main transmission gears in bridges, but it's pretty expensive undertaking. We emphasize that those who have even a jeep sometimes likes to drive will be forced to say goodbye to high speeds, as it is, first and foremost, it is dangerous (the car loses controllability), and the second - the acceleration and maximum speed of the machine will increase. Well, as a bonus - the speedometer and odometer will lie, as they make their calculations based on the tire size recommended by the factory. Body lift is more simple and safe to perform, it is done by installing shims between the frame and body. Together with the raising of the body almost does not raise the center of gravity, the car does not lose stability in turns and when applying bank. As the spacers can be used even ... hockey puck (the idea of ??Alexander Deryugina), but with the proviso that the puck will be one (washers can not put on each other, as the load on the bolts will be shattered and the design can fall apart at the most inopportune moment). If this distance seem a little, there is need to use one-piece steel wheel spacers, they are attached to the frame by welding. It is noteworthy that one of the best local civilian SUVs - Niva - no frame, so to install it on large-diameter wheels, you need to clip the wings. Liftovka suspension, on the contrary, the center of gravity shifts upward, which is why during cornering and the car rolls lose stability, riding on it is quite dangerous. Therefore, lift the suspension is considered to be a radical way - select the desired height of subtlety lies in finding a middle ground to the jeep passed well on the road, but did not overturn. It is important to note that the propeller shaft is the limiting angle at which their work is stable, and its reduction shafts wear faster, and even completely stop working. In some cases, to solve this problem by tilting up the main axis of the gear transmission. And to improve lateral stability to the machine is not overturned by a wheel spacers increases track width. Method of carrying out lifting the suspension depends on its design, in different cars, respectively, it is different. SUVs Series Nissan (Patrol GR), Toyota Land Cruiser (J8, LJ7, KJ7), Land Rover (Defender, Discovery, Range Rover), Mercedes (G) and Niwa (rear suspension) are equipped with spring suspension. When liftovke such machines can not be damaged "internal organs". Two longitudinal arm and reactive thrust lateral stability hold the bridges at a course down the bridge rests on springs, and up - cushions strikers. The springs are held between the frame and the bridge, their length and power specially designed for holding the machine in the middle position - to keep this characteristic constant ground mounting springs, pillows, bumpers and shock absorbers are transferred down to the height of the elevator. The spring is held in the socket with the power voltage. Made cup-spacers, the upper part of which is similar to a spring, and the bottom - the nest of its fastening. Cups are fixed in the nest to the frame with bolts or welding. For pillow-box-like bump manufactured spacer whose length equals the length of the cup spring (otherwise you'll have to replace a faulty shock absorbers or cushions, bumpers, the car will become more rigid or wheel will touch the wing). Further increases shock absorber, the change in length must be equal to the height lift. Absorber lengthened depending on the type of attachment - or transferring his mount down, or increase his stock with the help of two pins with thread, repeating the end of the rod shock absorber, and the screw holes where the screwed rod shock absorber. After liftovki traction-roll change - if you pull strongly deviates from the horizontal to the real state, then cross the bridge turn increases as "jumping" machines, and roll over short-lived. Therefore it is better to transfer their attachment to them was returned to his position, which was before tuning. On the domestic SUV - UAZah, as well as foreign Chevrolet (K-5) and Dodge (RAM) installed spring suspension, leaf springs are above the bridges. Lift such suspension is almost similar to the lift spring suspension - spacer is installed between the bridge and a package of springs. At the spacers should be a ledge, which it is inserted into the hole on a platform mounting springs, and a hole for the bolt that holds the spring pack. Ladders need to be replaced by thicker than the factory. Along with this process, experts advise to deploy the front spring shackles ago, this process is called Shakle Reversal. In cars with rear wheel anti-lock system to "negotiate" with a mechanism for disabling the rear brakes, which monitors the angle of inclination of the body by measuring the distance from the rear axle and the frame, in the case of strong tilting forward it disables the rear brakes. Accordingly, when lifting the body anti-lock rear brakes will be disabled. After liftovki spring suspension should always diagnose a car - raised his frame or bumper hanging up the wheels and check whether the hose is not stretched or not rested a steering pull in something, otherwise the suspension springs can destroy them. Care should be taken hob, not to violate its balance - it is necessary to make mark on the joints of his slotted (where the wheels are posted), remove the pedals and check the length of their connection, it should be such that kardan not cranked into the slot and that both sides were equal to the axes. Kardan return to the place to tread lightly, lest he got exactly the same way as before. Off-Road Series Jeep (Wrangler, Cherokee), Toyota Land Cruiser (J4, J6, J7), Land Rover (up-to-market model, Defender), Nissan Patrol (160/260) and Suzuki (Samurai) is set spring suspension, it is the most common variant, when the springs are located below bridges and fixed ladders. They and the spring and are carrying detail, the course is limited to the same spring spring suspension: Bottom - shock absorbers, upper - pillow-strikers. The most common way to lift such a suspension - SpringOver (Transfer of springs on the top bridges). It represents an increase in clearance and liquidation package springs. To install the springs on top of the bridge, you need to build and strengthen where new sites for the attachment. But the pitfall of this method is too great a height of lift, since it is composed of the thickness of the axle and spring package. Lift height can be reduced by the coup earrings springs - to fix it in a specially made bracket. This manipulation will increase the service life of springs. In addition, those who ventured into such a revision should be ready to unstable steering tie rods, brake hoses and universal joints. The angle of pins can be recovered by cutting the steering knuckle, and welding them upside down to turn around the axis of the bridge was compensated. Again, to maintain lateral stability necessary to expand the track. You can not move packages springs from under the bridge, and run extension springs, shackles, make a new attachment of springs or new springs with bending. True, all three options proposed, only the first is most common in practice - at elongation earrings springs lift is about half of its elongation, or if too long earrings reduced patency.
