Structural Differences

Construction grip on vaz change as the development of engines with increased displacement, and consequently increased the maximum power and torque. Currently There are two types of couplings: 2103 (for the engine capacity 1,2 l, 1,3 l, 1,5 x) and 2121 (1.6 liter engine). Actually clutch consists of two components: the casing (called "basket" or "basket") and the slave drive. Both types of coupling completely interchangeable and sites. With any of the baskets you can use any drive. External differences between types of clutches 2103 and 2121 are as follows.

I clutch disc friction linings 2103 diameters (outer and inner are 200 and 142 mm respectively). In 2121 slave drive relevant parameters have dimensions of 200 and 130 mm. The thickness of the new friction linings for all types of couplings – 3,3 mm. Petals clutch disc, which friction linings, alternately arched in opposite directions (to give the elastic properties of the slave drive, which provides a smoother clutch). The hallmark of "baskets" 2121 – label-hole of 6 mm between the petals diaphragm compression spring is located 15 mm from the edge of the central hole. Consider the "geometry" Clutch control:-the gap between the clutch bearing clutch and friction ring thrust flange push diaphragm spring about 2 mm, which corresponds to the displacement of the pusher of the worker (bottom) of the cylinder is 4-5 mm;-run thrust flange acting on the diaphragm spring, providing drainage the pressure plate to 1,4-1,7 mm is 8 mm, which corresponds to the displacement of the pusher of the working cylinder for 25-26 mm, the overall progress of the working cylinder pushrod approximately 30 mm, the gap between the pusher of the main (upper) cylinder and piston, in which it rests when you press the pedal, 0.1-0,5 mm, which corresponds to the move the pedals 0,4-2 mm – full speed the clutch pedal about 140 mm, adjustable free stroke, caused by gaps in the main pushers and the working cylinder, equal to 25-35 mm. These are the design features clutches vaz cars and drive.
