Abstract

Abstract 452,091. Reversing-gearing. RENAULT, L., 8, Avenue Emile Zola, Billancourt, Seine, France. Feb. 6, 1936, No. 3672. Convention date, April 16, 1935. [Class 80 (ii)] [See also Group XXXI] A vehicle transmission mechanism adapted to transmit power simultaneously from a primary shaft 1, Fig. 2, to two driving axles, 6, 7, Fig. 1, which are on opposite sides of it and are adapted to be driven alternatively in opposite directions, is characterized in that two secondary shafts 4, 5 are geared on the one hand to their respective axles 7, 6and on the other hand are interconnected by a gear pair 8, 9 so as to rotate in opposite directions, and means are provided for driving positively either secondary shaft at will from the primary shaft. In the form shown, a pinion 2 is splined on the shaft 1 and the change in direction of the vehicle is obtained by sliding the pinion 2 from engagement with a wheel 10 fast on the shaft 4 into engagement with a wheel 11 fast on the shaft 5. In another form, there are two constant-mesh pinions loose on the shaft 1 with a sliding double clutch between them. In a third form, the constant-mesh pinions are fast on the shaft 1 and the wheels 10, 11 are loose and adapted to be entrained by alternative clutches.
