5.120154DEVICE FOR CONTINUOUSLY CHANGING ROTATION SPEED RO - 30.09.2005 国际分类申请号 1999000068 申请人发明人 The invention relates to a device for continuously changing the rotation speed, by using a connecting rod-crank type system, to which, for continuously changing the rotative speed of a driven axle (1), this is placed with one-way rotation mobility, into a parallelipipedal piece (M) gliding without rotation, between two arms of a sliding bearing (L), which has one of the ends excentrically fixed, with freedom of rotation, to the edge of a disk (C) rotated with constant rotative speed, together with which it forms a connecting-rod-crank type mechanism, the changing of the rotative speed of the driven axle (1) being performed by modifying the value of the angle between the extreme positions of the sliding bearing (L) by a mechanism of controlled displacement, along the sliding bearing (L) of the parallelipipedal piece (M) together with the driven axle (1). In another variant, the said device uses two identical disks assemblies (C1 and C2), with excentrically fixed sliding bearing (L1 and L2), and parallelipipedal body (M1 and M2) with inner axle (1), compensatingly connected.
6.120186DEFORMABLE NON-PNEUMATIC WHEEL RO - 28.10.2005 国际分类申请号 2001000343 申请人发明人 The present invention relates to non-pneumatic wheels, especially to those which can replace the vehicle tyres. According to the invention, the deformable non-pneumatic wheel having a deformable structure, whose spokes (5, 52, 53 and 56) are located between the inner element (3) and the outer element (4) so that the flexibility thereof in a meridian plane is much less than their flexibility in a circumferential plane, the stabilizing means (6,7) limit the amplitude of a relative circumferential rotation between the inner element (3) and the outer element (4).
