Front elastic knot
1 – rubber element support plate; 2 – rubber element; 3 – axial bearing; 4 – upper plate for spring support; 5 - modern spring; 6 – coil spring; 7 – lower spring holder; 8 – shock absorber rod; 9 – nut; 10 – dust cuff; 11 – shock absorber protective tube
The front elastic unit, as already mentioned, is a mounting unit that combines a telescopic shock absorber with a modern spring and a coil spring. Since the front elastic unit forms the kingpin of the steering knuckle, at the bottom it is fixed in the bushing of the steering knuckle, and at the top its part is an axial bearing, allowing the top to rotate relative to the holder in the body frame.
At the bottom is a cylindrical casing of the front telescopic shock absorber with a welded bracket and a hole in it, inserted into a socket formed in the casting of the front wheel hub. The bracket is inserted into the split of the socket and a bolt is threaded into it (M10x1.25x65), compressing the socket and simultaneously forming a stop for the shock absorber body.
At the top of the shock absorber rod there is a dust seal, a modern spring (product of the company ELASTIGRAN), then a plate for supporting the coil spring, an axial bearing, then a plate and a rubber element designed for support on a recess in the body. The specified parts are tightened with a nut screwed onto the rod. The elastic unit assembled in this way is inserted from below into the recess in the body for support.
Another plate is put on top of the rod. It rests against the hole in the body. The said plate is secured with a nut screwed onto the thread of the protruding end of the shock absorber rod, and thus the elastic unit is secured at the top point.
The front elastic unit can be removed from the car entirely without the use of tools. However, to disassemble the elastic unit itself, a special tool from the SKODA service kit is required.
For different versions and modifications of Skoda Octavia cars, springs and shock absorbers of different parameters are assembled, and in addition, in different combinations according to the type of engine used, as well as equipment. The shock absorber has its code designation, on the spring the type is indicated by colored stripes.
