1,034,347. Shock absorbers. G. NAVARRO. July 13, 1964 [July 25, 1963], No. 28823/64. Heading F2S. [Also in Division B7] To limit rolling of a motor vehicle when negotiating a curve one or more of the shock absorbers connecting the sprung and unsprung parts of the vehicle includes an electromagnetic brake applied by a centrifugal switch to prevent relative displacement between the shock absorber cylinder 1 and piston 2. An annular series of electromagnets 4 separated by compressible plastic plates 6 are fixed axially but displaceable radially in an aluminium housing 3a forming part of a cover 3. When the windings 5 of the electromagnets are energized the polepieces 4a, 4b are applied against the cylinder 1 which is formed of ferromagnetic material. The centrifugal switch may be actuated by a pendulum or by mercury in a V- or U- tube containing contacts for completing a circuit from a battery to the windings 5 through an indicator lamp. In another embodiment (Figs. 1 and 2, not shown) a stirrup pivotally connected to the vehicle frame together with the shock absorber piston carries electromagnetic jaws embracing the shock absorber cylinder.
