Abstract: FIELD: aircraft. SUBSTANCE: spring aircraft brake has spring 2 placed in fixed housing 1 welded to wheel shaft 3. Spring acts on brake working member - shaped disk 4, placed in decorative shield 5. Spring acts on smooth side of disk 4. Profiles of other side of disk 4 are lifting and lowering curves and these profiles engage with rollers 6 welded to carrying disk 8 by mounting brackets 7. Engagement is provided by hydraulic system 10 applying force of pistons 11 to pressure disk 9 and, through the disk, to carrying disk 8. System operates as follows: when disk 9 hydraulically shifts forward carrying disk 8 provided with external splines for rigid coupling with wheel, rollers 6 press on profilles of stationary disk 4 and, through this disk, compress spring 2, as disk 4 is free to move along inner splines on shaft 3. If wheel rotates, rollers 6 will run over lifting and lowering surfaces of profiles of disk 4 (Dwg.2-Б,В). Owing to the fact that lifting surfaces Б have convex form and lowering surfaces B have concave form, peripheral component of force of spring 2 will mainly brake wheel, without accelerating the wheel when spring 2 is released on lowering surfaces B of profile. EFFECT: enlarged operating capability; possibility of using this brake together with landing brake. 1 dwg
