Class 79(2) Parasitic currents , generated in the, clutch of motor vehicle .are prevented from reaching the wheels , where they would cause interference to the radio receiver of the vehicle. In Fig. 1, periods of slip in the clutch 11, which may be electromagne t i c - ally actuated, give. rise to parasitic currents which flow through the gear box 15, the differential gear 24, and universal joints 26 to the halves of the rear axle which are fitted with insulating joints 34 to prevent the currents from reaching the wheel assemblies 29...33. The joint 34 may be provided at any other position between the clutch and wheels and may consist of a pair of insulated radial flanges. In Fig. 2, the currents are by-passed to the vehicle chassis by a condenser having one plate 42 secured to a shaft 12 and a pair of plates 43 loaded by springs 46 and connected at 44 to a casing 45 on the chassis, a film of oil between the plates serving both as a lubricant and a dielectric. A condenser may also be formed by fitting two spring-loaded half cylinders of bronze around the shaft. The condensers may be fitted on the shafts of the gear box which may alternatively form a direct electrical connection with the vehicle chassis as shown in Fig. 5. The centre 60 formed for machining the shaft 14 makes non-rotational engagement with a ball 61 against which a plunger 62 is held by a spring 65. The plunger is mounted in a socket 63 having a pair of slots 66, 67, one of which receives a stud 68 to prevent rotation of the plunger while the other forms a passage 67 for a cable 69 connecting the plunger to a thimble 70 clamped under a nut 71. Materials of different hardness such as steel and brass or bronze are used for the ball and plunger so that, in operation, a depression is formed in the latter to provide a good electrical contact. In alternative constructions, the plunger is carried by a cup 72, Fig. 6, which is prevented from rotating either by a tongue punched out of the cup to engage a hole in the housing or by a tongue which passes through a slot 76 in the cup and is held in place by a semicircular blade fitting within the cup. The rear axle of the vehicle may be directly earthed instead of a gear box shaft.
