Abstract

544,936. Hydraulic torque converters ; variable speed gears. HOBBS, H. F. Oct. 28, 1940, No. 15753. [Class 69 (ii)] [Also in Group XXIV] A hydraulic torque converter which can transmit power at variable speeds comprises a drum 16 in which are arranged one or two spindles 13 carrying pump wheels 14 having vanes in the form of rollers 15, the drum 16 being arranged in a housing 20 which is secured to the output shaft 21 by rivets 22, the input flywheel 10 being connected by an annular gear 11 to gears 12 on the spindles of the wheels 14. The drum 16 also carries one or two reaction wheels or motors 18 having roller vanes 19, and the spindles 17 of these wheels are fitted with gears 24 which engage a fixed gear wheel 25. The drum 16 is connected by rivets 29 to a sleeve 30 on the output shaft 21, and by means of a sliding collar 40 which displaces balls 33 arranged between a groove parallel to the axis of the gear 25 and inclined slots 36 in sleeve 30, angular adjustment can be effected between the drum 16 and the housing 20 and pump spindles 13, 17, so that variation can be effected in the capacity of the pump and motor wheels and so of the transmission ratio between the engine speed and speed of a car. The collar 40 can be operated by a throttle pedal control so as to reduce the eccentricity of the pump as the engine throttle is opened. The spindles 13, 17 are arranged to be concentric or eccentric to the chambers in which the vanes 19 work, and if one is concentric the eccentricity of the other is at its maximum. On actuation of the collar 40 the eccentricities are varied in the opposite sense so that if the eccentricity of the spindles 13 is increased that of the spindles 17 decreases. In a modification the ball vanes 15, 19 are replaced by sliding vanes of a piston-like form. In place of a fixed gear 25 which is connected to the re-action wheels a second input or driven shaft may be used, or two output shafts may be used, Oil is replenished by a pump 72 which delivers from a sump through a pipe 73 and channels 77, 78, 79. Specification 536,977 is referred to.
