The invention discloses a novel interaxial differential structure of a through axle and belongs to the technical field of through axles. According to the novel interaxial differential structure, a half axle gear on one side and a driving cylindrical gear are of an integrated structure, and a planet gear is of a split combination structure, so that the planet gear is connected with a planet carrieradvantageously. Spacer structures are adopted between the half axle gears and the planet carrier to achieve axial position. Power transmitted from a cylindrical gear shaft is transmitted to the planet gear through the planet carrier. When no differential speed exists, no relative movement exits between the planet gear and the half axle gears, and revolution is conducted together; and when the differential speed exists, the planet gear rotates the half axle gears on the two sides are different in rotation speed, and thus the purpose that the differential speed exists between the through axle and a rear axle is achieved. According to the interaxial differential structure of the through axle, through the cylindrical-gear-shaped half axle gears and the cylindrical-gear-shaped planet gear structure, damage of axial force to parts is reduced; and the spacer structures are adopted between the half axle gears and the planet carrier to achieve axial position, the abnormal sound due to axial displacing of the parts is avoided, and through the structures, the reliability of the interaxial differential speed is improved to a large extent.
Description
technical field [0001] The invention belongs to the technical field of through-axles, and in particular relates to a novel structure of a differential between axles of a through-axle. Background technique [0002] At present, the inter-axle differentials of domestic through bridges mostly adopt the structure of the half-shaft gear of the bevel gear and the planetary gear of the bevel gear. Due to the large axial force generated during operation, this structure often causes premature wear of related parts; due to the difficulty in axial positioning, this structure often causes related parts to move axially and produce abnormal noise. With this patented structure, the inter-axle differential of the through bridge adopts a cylindrical toothed half shaft wheel and a cylindrical toothed planetary gear structure, which reduces the damage to the parts caused by the axial force. A gasket structure is used between the half-shaft wheel and the planetary wheel carrier to achieve axial...
