DIFFERENTIAL TORQUE DIVIDER WITH SPROCKET FOR ROLLER CHAIN

Description

1 / 3 DIFFERENTIAL TORQUE DIVIDER WITH ROLLER GEAR FOR ROLLER CHAIN ​​{001} This utility model application, to be used in the mechanical industry, concerns a differential torque divider with a roller chain, which is a compact geometry device designed for severe road conditions in various conditions, operating on trailers towed by adapted motorcycles. The differential compensates for turns with one wheel rotating faster, maintaining torque parity on both sides. {002} Traditionally, the roller chain system is a mechanical device used to transmit power between two or more shafts that are a certain distance apart. It consists of a series of articulated links, where each link is formed by side plates, pins, bushings, and rollers. The rollers are the parts that come into direct contact with the gears, promoting movement and minimizing wear between the parts. These chains are widely known for their robustness and ability to transmit high torque force, being essential in systems requiring high reliability, as their operation is based on the transmission of power between two gears, which are the sprockets, through the chain links. The differential calculation will be part of the process according to the new gearing presented by these chains. So, basically, this is the standard model existing throughout the consumer market. {003} The present model presented in this application is equipped with two semi Petition 870250015572, dated 26 / 02 / 2025, page 6 / 14 The assembly consists of 2 / 3 shafts, which receive torque from the bevel gears, and these, in turn, receive torque from smaller bevel gears called satellite gears. The torque from the roller chain, which passes through the roller ring, is transmitted through the smaller bevel gears as a tangential force, and also through the larger bevel gears, each of which is attached to a half-shaft on either side. The rotational speed is compensated for by the rotation of the smaller bevel gears, designated as satellite gears, in seats within the tube extension of the ring. The mechanical assembly moves within a lubricated, sealed, low-friction compartment. {004} In this present utility model application, the innovations can be better understood through the attached figures, when the analysis is carried out in conjunction with this descriptive report. Figure 1 shows a cutaway view distinguishing sufficient components to understand the operation. The movement enters through the roller chain sprocket (1) which supports four satellite sprockets (2) coupled to the planetary sprockets (3), these connected by circumferential fillet welding to the bearing seat extension (7). This pair of larger sprockets are coupled to the pair of tubular half-shafts (6) by means of rivet pins (10). This figure shows the shaft (5) with a central shoulder transmitting compression from one half-shaft to the other. The traction between the half-shafts is contained by the bolted two-part coupling with alternating parts forming an integral assembly. The mechanism operates immersed in lubricant. The housing is sealed by the retainers (11) located between the covers and the body of the planetary sprocket and between the solid shaft (5) and the tubular half-shaft (6). The sliding of the satellite sprockets in this compensating rotation Petition 870250015572, dated 26 / 02 / 2025, page 7 / 14 3 / 3 of the movements occur in the inner seats of the bushings (12). {006} FIGURE 2 shows the central shaft (5) in contact with the half-shaft (6) on each side. The pin (10) connects the half-shaft on each side with the extension of the larger planetary gear wheel. {007} FIGURE 3 shows the smaller satellite crown, having a cylindrical seat for fitting into the bushing installed on the toothed disc for rollers, the part through which the differential drive movement enters. The coupling for angular movement occurs through the teeth (19) conical plane, having common pitch diameters with the larger planetary wheel (3). {008} FIGURE 4 shows the larger conical crown (3), called planetary in this differential mechanism because the smaller ones (2) rotate around it. {009} FIGURE 5 shows the toothed crown (1) driven by a roller chain. The teeth (16) are contact seats for the rollers of the drive chain. This crown has a side tube with 4 holes (17) seats for the satellite toothed wheels. {010} FIGURE 6 shows the coupling (4) supporting the two half-shafts in position, free from separation, when subjected to traction under the action of an external force. It is composed of two split flanges (13), with lines (14) indicating the contact face. The assembly is offset by 90° to maintain the assembly's stability. Tightening is done with screws having a thread on one side of the coupling and a hole on the other. {011} A pair of bearings (7) provide longitudinal location stability of the differential device in the vehicle. They are shielded, lubricated for life. Petition 870250015572, dated 26 / 02 / 2025, p. 8 / 14
