Problems solved by technology
When the car transmission is in direct gear, the gears in the transmission are idling with no load, resulting in unnecessary energy consumption, especially the idling gears continue to stir the gear oil in the transmission, and the power caused by this churning The loss is still relatively large
In addition, long-term high-speed idling gears will wear the tooth surfaces of the gears and the countershaft bearings. For a single countershaft transmission, it will also wear the needle roller bearings of the two shafts, which will increase the probability of transmission failure and shorten the product life. , increased noise

Embodiment Construction
[0014] The content of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0015] Such as figure 1 Shown: this embodiment is double countershaft speed changer, has six forward gears and a reverse gear (wherein one gear and reverse gear transmission are identical with existing speed changer, so do not draw), each gear position shown in the figure The positions are only indicative, actual gear positions can be arranged upon request. This oil-saving transmission has an input shaft 1, an output shaft 2 and two intermediate shafts 3 (only one intermediate shaft is shown in the figure), and the input shaft gear 4 is vacantly sleeved on the input shaft 1, which is constantly meshed with the intermediate shaft transmission gear 5 , each gear gear on the intermediate shaft is combined with the intermediate shaft, and each gear on the output shaft is vacantly sleeved on the output shaft. The input shaft 1 is provided with a double ta...

The invention provides an automotive oil-saving transmission to solve the problems of keeping an intermediate shaft from rotating when a direct gear is put into place to avoid unnecessary power loss occurring during oil mixing. The transmission comprises an input shaft, an output shaft and the intermediate shaft. A gear of the input shaft is constantly meshed with a drive gear of the intermediate shaft, but the gear of the input shaft is sleeved on the input shaft. The input shaft is provided with a synchronizer of the input shaft which rotates together with the input shaft. The synchronizer of the output shaft selectively combines with the gear of the input shaft or with the output shaft through shift operation mechanism. After the synchronizer of the input shaft leaves the gear of the input shaft and combines with the output shaft, the input shaft is connected with the output shaft through the synchronizer, and, at the same time, the gear of the input shaft as well as the drive gear of the intermediate shaft, shifting gears on the intermediate shaft and the shifting gears on the output shaft do not rotate; and after the synchronizer of the input shaft combines with the gear of the input shaft, the transmission serves as a common transmission.
Description
technical field [0001] The invention belongs to a gear transmission device with a variable speed ratio, in particular to an automobile fuel-saving transmission. Background technique [0002] The transmission structure of the existing automobile transmission is: the gear (one shaft gear) of the input shaft (also known as the first shaft) is constantly meshed with the transmission gear of the intermediate shaft, and the gear gear on the intermediate shaft is in contact with the output shaft (also known as the second shaft) The range gears on the transmission are meshed, so all the gears in the transmission are turning regardless of the state. Expressways have become the backbone of highway traffic at present. In order to run fast in Dora, drivers generally like to hang direct gears on the expressway, that is, the input shaft and output shaft of the transmission are connected together. When the car transmission is in direct gear, the gears in the transmission are idling with n...
