Improved type auxiliary transmission

Abstract

The invention provides an improved type auxiliary transmission. The improved type auxiliary transmission comprises a transmission housing, an auxiliary speed change input shaft, a duplicate driving gear, an auxiliary speed change output shaft, a duplicate driven gear, a first-grade deep groove ball bearing, a second-grade deep groove ball bearing, a shaft sleeve, a speed change pull rod, an end cover, an oil filling filter screen structure, a quick mounting adjustable rod structure and an oil filling detecting probe structure; the horizontal middle position of the auxiliary speed change inputshaft is connected to the middle position of the left wall of the inner side of the transmission housing by virtue of a bearing; and the duplicate driving gear is connected to the right position of the outer wall of the auxiliary speed change input shaft by virtue of a key. According to the improved type auxiliary transmission provided by the invention, by arranging an oil cover, a locking bolt, afixing seat and an oil guide box, oil can be beneficially fed into the oil guide box, so convenience is provided for storage, and convenience is also provided for dismounting; by arranging an L-shaped supporting seat, an oil leaking ring, an oil filter net bag and an oil discharging hole, the oil filter net bag can be beneficially dismounted, maintained and placed; meanwhile oil can continuouslyflow into the transmission housing via the oil discharging hole; and thus the lubricity of all gears is guaranteed.

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...
