VAZ-2114: front and rear suspension

By car VAZ-2114 suspension is more modern, it differs in design from previous models. Owners who decided to service their cars on their own should be interested in understanding the issues of the suspension system, as well as in the subject of running gear repair. Today we will pay special attention to this issue.

Front suspension: how it is arranged

The front suspension of the VAZ-2114 is independent, telescopic.

The system uses shock absorbers - gas or hydraulic type, helical springs, transverse levers, as well as stabilizers, responsible for the transverse stability of the car. At the heart of the design is a detail that performs a swivel and support function - a front suspension rack. This element is a unit consisting of a shock absorber and a coil spring.

The knot is fixed to the swivel fist of the wheel hub with brackets. Part of the main suspension element or the car rack is held in the upper part of the body in a special glass and fixed on three bolts. This unit is also equipped with a pivot. It is necessary for fastening the steering rods.

Also, the front suspension includes wheel hubs, ball bearings, special bearings, brake system components. The ball valves are mounted fixedly on the lower levers of the front suspension system. Fingers of supports are installed in the seats on the wheel hubs and fixed with nuts. The lower arm of the VAZ-2114 suspension is installed and fixed on a special element - a stretch. It has two ends that are attached to the body spar through brackets. One side of this extension is used to fix the stabilizer, where its end is installed. On the second is the next half of the stabilizer. So the element ties the two wheels together.

Principle of operation

This is how the front wheels are suspended on the VAZ-2114.

The system itself operates according to the following principle: the rack and the spring act simultaneously, are the supporting and damping element for the car. Due to the use of stretch marks and levers in the system, support is provided for the entire assembly in its lower part. Also, the system is kept from moving in the longitudinal axis of the car's body. The driving wheels can be rotated by means of steering rods - when the steering wheel is turned, they pull on special ears, located directly on the racks. The whole assembly rotates completely.

Its upper part is rotated by the support bearing, and the lower part by the ball bearings. Thanks to the presence in the stabilizer system, the front suspension VAZ-2114 is tied together and can be synchronized.

Rear and its device

At the rear, the system is much simpler than the front. There is a dependent suspension. This is a rigid transverse beam of continuous type. A continuous beam is used as a basis. This is a metal part made by welding. Its shape resembles the letter "H", but here the transverse part is longer. The front ends of this metal beam is attached to two brackets, which are bolted to the side members in the rear of the car. The method of mounting the brackets holding the beam is hinged on the rubber blocks.

On the rear ends of this suspension element there are places for mounting wheel hubs. They are installed on special flanges and fixed with bolted connections. They also have elements of the brake system. Two-row bearings are installed inside the wheel hubs. On the other hand, a column and a coil spring are attached to the rear ends of the beam. The upper part of the shock absorber is installed in a glass. The latter is welded to the body of the car.

Rear suspension work

How does the rear suspension VAZ-2114? This transverse beam, in accordance with the principle of operation, resembles a pendulum. Since the part through brackets is held on the spars, it can not physically move in the longitudinal axis of the car's body. Stands with springs serve as a stop for the beam and are both cushioning and supporting elements.

Typical malfunctions

Most often, all problems with the suspension on this car can be solved with their own hands. Symptoms of malfunctions are often associated with breakage of shock-absorbing racks. They are the most loaded elements in the car VAZ-2114. Suspension perceives the dynamic load from the wheels of the car at the time of driving over the uneven surface, as well as the lateral load that the steering rods create. Racks are a significant problem. But there are more minor breakdowns. They are associated with the wear of various rubber seals and silentblocks. It is also possible to loosen the bolted connections. To eliminate these faults, replace the worn seal. Repair of VAZ-2114 suspension means replacement of racks, springs, silentblocks. To dismantle the rack, you must have special tools. All other tools are standard, and can be found in the garage. Special tools - this is a coupler for dismantling the springs, as well as a puller for pressing the pin of the steering rod.

How to disassemble and replace the front suspension elements?

First of all, the car is installed on a pit, overpass or raised with a lift.

It is better to put the car on the parking brake. Decorative caps must be removed from the wheels. It is also recommended that the bolts be loosened and the hub nut removed. When the front of the machine is locked, the wheel is pulled out. Next, take out the finger of the ball bearing, which is installed in the pivot arm on the front pillar. Next , the stabilizer strut will be dismantled from the lever. Then remove the stretch, then completely detach the ball joint, which is held on the pivot. At the next stage the lever is removed - for this purpose it is disconnected from a bracket on a body. Also completely remove the bolts, with the help of which the pads are attached to the swivel fist.

The support can be missed - enough to hang it so that the hose is not damaged. After that, the spline shank and the hub are pressed out. A protective fist is removed from the bonnet. To do this, remove the rack nuts and then remove the element completely. Also, the other rack is removed. Changing the suspension VAZ-2114 involves the dismantling of worn parts and installation of new in the reverse order. But it is necessary to take into account some features. When mounting the bracket to the car body, it must be ensured that the threads in the sleeves are not damaged.

Disassembling the rear suspension with your own hands

Knowing the suspension device VAZ-2114, you can disassemble it competently and quickly, and with your own hands. The first thing to do is to find a pit or a lift. In the trunk, disconnect the lining, and loosen the nuts holding the posts. Then unscrew the wheel bolts. Next, dismantle the braking system cables. It is best to do this in the collection.

After that, remove the drum, nozzles and hoses of the brake system. Now you can go to the racks. In order to detach them, remove the rubber cushions, nuts and washers on the body. Then install additional stops for the front wheels. The back part should be raised. After this, you can remove the springs and racks. When the brackets for fixing the beam to the body are removed, then the whole beam can be removed. On the car VAZ-2114 suspension is arranged quite simply. You can easily replace worn parts and reassemble in reverse order.

Conclusion

As you can see, the system design is simple, and its independent repair does not present any special difficulties. With regular maintenance, lubrication and replacement of worn parts, the driver will not hear knocking, and the machine will please the smooth running and good handling.
