4.6.16 Multi-disk foot and parking brakes operating in oil bath
In order to enhance efficiency, reliability and service life of tractor brakes the tractors of series
“1000” are equipped with multi-disk brakes operating in oil bath (“wet” brakes). Clutch of rear axle
differential interlock is mounted inside brake body, and has oil bath common with it, so it is also
made in “wet” version. Design of brake (Figure 4.144).
Foot brakes –
eight-disk. Friction disks (2) are installed on spline ends of drive gears of final
drives (16). In design pressure disks (6) are similar to those used in dry brakes, except for smaller
angle of balls’ hollows to provide necessary effort for compression of stacks of friction and
intermediate disks.
