Problems solved by technology

[0002] The automobile transmissions currently used in domestic logistics vehicles are mostly five-speed and six-speed, with high-speed gears in front and low-speed gears in the rear. Large and overdrive gears are easily damaged, difficult to shift gears, and work intensity is high, which makes it difficult to meet the multi-directional and rapid development of logistics vehicles. The level of lubricating oil brings sufficient lubrication, but the shaft of the automobile transmission is horizontally distributed, so there are technical problems such as low shift efficiency and prone to failures

Abstract

The invention belongs to the technical field of automotive transmissions, and particularly relates to a novel automotive transmission. The novel automotive transmission comprises an intermediate box housing, a front housing connected in front of the intermediate box housing and a back housing connected behind the intermediate box housing. The automotive transmission is of an upper-lower shaft type transmission structure and adopts an output speed-reducing mode, and the output part is constant mesh; the transmission comprises an input shaft assembly, an intermediate shaft assembly, an output shaft assembly and a reverse idler gear assembly; the input shaft assembly and the intermediate shaft assembly are distributed up and down; the input shaft assembly comprises an input shaft, a fourth speed gear, a first lock ring synchronizer, a fifth speed gear, a sixth speed gear and a second lock ring synchronizer. The novel automotive transmission provided by the invention has the advantages of great carrying capacity, great gear quantity, all synchronizer gear shifting, distribution of speed ratio matching according to partial geometric progression, convenience in gear shifting, environmental-friendliness and energy conservation and the like, is high in adaptability in various working conditions and road conditions, and can better meet the current development demand on automobile at home.

Description

technical field [0001] The invention belongs to the technical field of automobile transmission parts, and in particular relates to a novel automobile transmission. Background technique [0002] The automobile transmissions currently used in domestic logistics vehicles are mostly five-speed and six-speed, with high-speed gears in front and low-speed gears in the rear. Large and overdrive gears are easily damaged, difficult to shift gears, and work intensity is high, which makes it difficult to meet the multi-directional and rapid development of logistics vehicles. Lubricating oil under the horizontal surface brings sufficient lubrication, but the shaft of the automobile transmission is horizontally distributed, which has technical problems such as low shift efficiency and prone to failure. In view of this, the applicant provides a novel automobile transmission, and this case arises therefrom. Contents of the invention [0003] The purpose of the present invention is to pr...
