An improved auxiliary transmission

Abstract

The invention provides an improved auxiliary transmission, which includes a transmission housing, an auxiliary transmission input shaft, a duplex driving gear, an auxiliary transmission output shaft, a duplex driven gear, a first-level deep groove ball bearing, and a second-level deep groove ball bearing , shaft sleeve, shift lever, end cover, oil filling filter structure, quick installation adjustable lever structure and oil filling detection needle structure, the lateral middle position bearing of the auxiliary transmission input shaft is connected to the middle left wall of the inner side of the transmission housing Position; the key of the duplex driving gear is connected to the right part of the outer wall of the auxiliary transmission input shaft. The arrangement of the oil cover, the locking bolt, the fixing seat and the oil guide box in the present invention is beneficial to oil filling inside the oil guide box, which is convenient for storage and easy to disassemble; the L-shaped support seat, the oil leakage ring, and the oil filter net pocket And the setting of the oil outlet hole is conducive to disassembly and maintenance and replacement of the oil filter bag, and at the same time, the oil can continuously flow to the inside of the transmission housing through the oil outlet hole to ensure the lubricity of the gears at all levels.

Description

technical field [0001] The invention belongs to the technical field of automobile transmissions, in particular to an improved auxiliary transmission. Background technique [0002] Existing three-wheeled vehicles, because there is only one main transmission, its traveling speed is all faster, when traveling on country road, because its road is narrow, uneven, safety is relatively poor; Lack of power on the steep slope and hindered. Although auxiliary transmissions have been used in the market to decelerate to increase power, there are at least three drive shafts in the auxiliary transmissions, which have complex structures and high production costs. Some auxiliary transmissions are installed on the rear axle, away from the main transmission, and the structure is loose. Therefore, it is necessary to optimize the design of the auxiliary transmission. [0003] The Chinese patent publication number is CN203717807U, and the name of the invention is a auxiliary transmission, whic...
