Description
Technical Field
The invention belongs to an automobile transmission, in particular to a manual rear-drive five-gear transmission.
Background
In the existing manual rear-drive five-gear transmission, the transmission ratio of the first-gear pair and the transmission ratio of the reverse gear pair are the largest. Therefore, the torque transmitted by the two pairs of gear pairs is the greatest, and the working stress borne by the gear teeth is the greatest, and the weak link in strength in the manual rear-drive five-gear transmission is common.
Referring to fig. 1, a manual rear-drive five-gear transmission commonly used in the market comprises an input shaft 1, an output shaft 3, an intermediate shaft 2 parallel to the distance between the input shaft 1 and the output shaft 3 and a reverse idle gear shaft 4, wherein a first-gear driving gear 5, a reverse driving gear 15, a second-gear driving gear 7, a five-gear driving gear 13, a five-gear synchronizer 21, a three-gear driving gear 9 and a three-four-gear synchronizer 20 are sequentially installed on the input shaft 1, a first-gear driven gear 6, a second-gear driven gear 8, a five-gear driven gear 14, a three-gear driven gear 10 and an intermediate shaft constant-engagement driving gear 12 are sequentially installed on the intermediate shaft 2, a first-gear driven gear 6, a second-gear driven gear 8, a five-gear driven gear 14 and a three-gear driven gear 10 on the intermediate shaft 2 are respectively meshed with the first-gear driving gear 5, the second-gear driven gear 8, the five-gear driven gear 14, the intermediate shaft constant-engagement driving gear 11 and the reverse idle gear 16 on the intermediate shaft 3, and the reverse idle gear 16 on the intermediate shaft 3 are respectively meshed with the first-gear driving gear 5, the second-gear driven gear 7, the idle gear 13 and the first-gear driven gear 1, the intermediate shaft constant-gear 16 on the intermediate shaft 1, and the reverse idle gear 16 are meshed with the intermediate shaft 12 on the intermediate shaft 3. The technical problems of the manual rear-drive five-gear transmission are that;
the first gear driving gear 5 and the reverse gear driving gear 15 on the input shaft 1 are of split structures and are common straight-tooth gears with smaller width, and the widths of the straight-tooth gears are smaller, so that the strength is lower. The first-gear driving gear 5 can meet the use requirement by adopting special processes such as shot blasting and the like, and the manufacturing cost is high, so that the manufacturing cost of the whole manual rear-drive five-gear transmission is also high.
The reverse drive gear 15 is arranged on the input shaft 1 separately from the first drive gear 5 at a distance from each other, so that the input shaft 1 must be long in order to meet the assembly requirements of the reverse drive gear 15 and the first drive gear 5, i.e. the input shaft 1 is long. This results in an overall length increase of the transmission, taking up more space, weight and bulk.
The reverse idler gear 16 is a straight-tooth gear with a smaller width, and needs to axially slide a certain axial distance to be engaged into the reverse driving gear 15 and the reverse gear sleeve 19-1 of the two-gear synchronizer 19 to realize reverse gear. During the first gear, the reverse sleeve 19-1 of the first and second synchronizers 19 is required to axially yield to avoid interference. It is then also necessary to increase the axial distance between the reverse drive gear 15 and the first drive gear 5, and also to increase the length of the input shaft 1. Also, the overall length of the transmission is increased, taking up more space, weight and volume.
The reverse gear structure of the three gear chain transmission of the reverse gear driving gear 15, the reverse gear idler gear 16 and the reverse gear sleeve 19-1 of the two-gear synchronizer 19 can generate larger transmission errors and vibration noise.

In order to solve the technical problems, the manual rear-drive five-gear transmission comprises an input shaft and an output shaft which are coaxial, an intermediate shaft parallel to the distance between the input shaft and the output shaft and a reverse gear idler shaft, wherein a first-gear driving gear, a reverse gear driving gear, a second-gear driving gear, a fifth-gear synchronizer, a third-gear driving gear and a third-fourth-gear synchronizer are sequentially arranged on the input shaft, a first-gear driven gear, a second-gear driven gear, a fifth-gear driven gear, a third-gear driven gear and an intermediate shaft constant-engagement driving gear are sequentially arranged on the intermediate shaft, an output shaft constant-engagement driven gear is arranged on the output shaft, a reverse gear idler gear is arranged on the reverse gear idler shaft, and the first-gear driven gear, the second-gear driven gear, the fifth-gear driven gear and the third-gear driven gear on the intermediate shaft are respectively engaged with the first-gear driving gear, the second-gear driving gear, the fifth-gear driving gear and the third-gear driving gear on the input shaft, and the intermediate shaft constant-engagement driven gear is characterized in that: the gear transmission mechanism is characterized by further comprising a reverse gear output gear which is arranged on the intermediate shaft and is positioned between the second-gear driven gear and the fifth-gear driven gear, wherein the reverse gear idler gear on the reverse gear idler shaft is a duplex gear and comprises a first-stage idle reverse gear idler gear, a reverse gear synchronizer gear sleeve and a second-stage idle reverse gear idler gear, the first-gear driving gear and the reverse gear driving gear on the input shaft are wide gears in an integrated structure, the width of the wide gears is equal to the sum of the widths of the first-gear driven gear on the intermediate shaft and the first-stage idle reverse gear idler gear of the reverse gear idler gear on the reverse gear idler shaft, the reverse gear driving gear on the input shaft is meshed with the first-stage idle reverse gear idler gear of the reverse gear idler gear on the reverse gear idler shaft, and the second-stage idle gear idler gear on the reverse gear idler gear is meshed with the reverse gear output gear on the intermediate shaft.
After the structure is adopted, the invention has the following beneficial effects;

The use requirement can be met without adopting special processes such as shot blasting and the like to treat the first-gear driving gear and the reverse-gear driving gear, and the manufacturing cost is low, so that the manufacturing cost of the whole manual rear-drive five-gear transmission is also low.
The first-gear driving gear and the reverse-gear driving gear are of an integrated structure, and are not required to be arranged on the input shaft independently at intervals, namely, the length of the input shaft is smaller, so that the assembly requirements of the reverse-gear driving gear and the first-gear driving gear can be met, namely, the length of the input shaft is reduced, the overall length of the transmission is reduced, and the transmission occupies smaller space, weight and volume.
The reverse gear idler gear is a duplex gear and comprises a first-stage idle reverse gear idler gear, a reverse gear synchronizer gear sleeve and a second-stage idle reverse gear idler gear, and load born by the reverse gear idler gear can be distributed to the first-stage idle reverse gear idler gear and the second-stage idle reverse gear idler gear. Thus, the strength is high and the load can be borne high.
The reverse gear idler wheel is a duplex gear, a reverse gear driving gear on the input shaft is meshed with a first-stage idle reverse gear idler wheel of the reverse gear idler wheel on the reverse gear idler wheel shaft, a second-stage idle reverse gear idler wheel of the reverse gear idler wheel is meshed with a reverse gear output gear on the intermediate shaft, and transmission errors and vibration noise generated by chain transmission between the reverse gear idler wheel and the reverse gear output gear are small.
Preferably, the first gear driving gear and the reverse gear driving gear on the input shaft are manufactured by adopting a hobbing process. This results in lower manufacturing costs for the first gear drive gear and the reverse gear drive gear.
Preferably, the first-gear driving gear and the reverse-gear driving gear are spur gears, and correspondingly, the first-stage idle reverse-gear idler gear in the reverse-gear idler gear is also a spur gear. This results in a better engagement of the primary idler of the primary drive gear with the reverse idler, with less transmission errors and vibration noise.
Preferably, the first-gear driving gear and the reverse-gear driving gear are helical gears, and correspondingly, the first-stage idle reverse-gear idler gear in the reverse-gear idler gears is also a helical gear. This results in better engagement of the primary idler gear of the first gear drive gear with the primary idler gear of the reverse gear idler gears, and less transmission errors and vibration noise.
