Abstract
The invention relates to a rear auxiliary transmission assembly which is provided with a transmission body; a flanged shaft is arranged on one side of the transmission body; an auxiliary shaft is arranged on the other side of the transmission body; an intermediate shaft is arranged in the transmission body; a high-low-gear toothed gear is mounted at the inner part of the transmission body with the flanged shaft in a sliding manner; a dual gear is arranged on the intermediate shaft, and is in transmission connection with the auxiliary shaft through an auxiliary shaft gear; the high-low-gear gear is in meshed transmission with the dual gear on the intermediate shaft through the shifting of a shifting fork; the shifting fork is positioned and slides on a shifting fork shaft through coordination of a spring, a steel ball and a shifting fork shaft hole. The rear auxiliary transmission assembly is suitable for various light trucks, thereby having the advantages of strong universality, convenience in mounting and maintaining, labor and time saving, and low cost.
Description
Technical field
The invention belongs to a kind of automobile gearbox, concrete is a kind of gearbox of light card lorry.
Background technique
Gearbox mainly refers to the gearbox of automobile, and it is divided into manual, automatic two kinds, and manual transmission is mainly made up of gear and axle, produces variable-speed torque-converting by different Gear combination; And automatic transmission case AT is made up of torque converter, planetary pinion and hydraulic control system, reach variable-speed torque-converting by the mode of fluid power transmission and Gear combination.Function is: one, change velocity ratio; Two,, in the constant situation of hand engine rotation, automobile can be fallen back and travel; Three, utilize neutral, interrupt transmission of power, with motor can start, idling, and be convenient to shifting of transmission or carry out power output.
The motor of existing light card lorry connects rear secondary rear auxiliary transmission by transmission shaft at present, because the model of light card lorry is various, gearbox is also the model that coupling is identical with motor, in the time that gearbox breaks down or damage, need to find the gearbox of same model, could with the propeller shaft couplings of motor, install simultaneously, maintenance is inconvenient, takes time and effort, and cost is high.
Summary of the invention
The object of the invention is in order to address the above problem, propose a kind of after auxiliary transmission assembly, it is convenient that this rear auxiliary transmission assembly has design science, rational in infrastructure, highly versatile, installation, maintenance, the feature time saving and energy saving, cost is low.
The object of the invention is to be achieved through the following technical solutions: rear auxiliary transmission assembly, be provided with gearbox casing, it is characterized in that: described gearbox casing one side is provided with flange shaft, described gearbox casing another side is provided with a secondary axle, in described gearbox casing, be provided with jack shaft, in institute's flange shaft gearbox, part is slided high and low shift gear is housed, described jack shaft is provided with duplicate gear, described duplicate gear is connected with a secondary shaft drive by a secondary shaftgear, described high and low shift gear by shift fork stir with jack shaft on duplicate gear engagement driving, described shift fork passes through spring, steel ball, slide in the location on declutch shift shaft that is engaged in of shift fork axis hole, the shifting block of described shift fork is fixed on shift lever axis by resilient key.
Further, described duplicate gear is arranged on jack shaft by needle bearing spacer, needle bearing 64905.
Further, described flange shaft is arranged on casing by deep groove ball bearing 6209, skeleton-type oil seal, and described deep groove ball bearing 6209 uses snap ring %c45X1.5 to be fixed in flange shaft by axle.
Further, a described secondary axle is fixed on casing by hole snap ring %c85X2, deep groove ball bearing 6204, flange spacer, skeleton-type oil seal.
Further, between described flange shaft and a secondary axle, be slidably connected by front stop ring %c20X%c3.5, needle bearing 64904.
Gearbox casing one side of the present invention is provided with flange shaft, gearbox casing another side is provided with a secondary axle, in described gearbox casing, be provided with jack shaft, in blue shaft gearbox, part is slided high and low shift gear is housed, jack shaft is provided with duplicate gear, duplicate gear is connected with a secondary shaft drive by a secondary shaftgear, high and low shift gear by shift fork stir with jack shaft on duplicate gear engagement driving, shift fork passes through spring, steel ball, slide in the location on declutch shift shaft that is engaged in of shift fork axis hole, the shifting block of shift fork is fixed on shift lever axis by resilient key, the output terminal of motor is directly connected with pair one axle of gearbox, do not need to connect by transmission shaft, overall construction design is used gearbox to be suitable for various light card lorries and uses, thereby there is highly versatile, install, easy to maintenance, time saving and energy saving, the feature that cost is low.
