Abstract
The utility model discloses a five-gear thrust washer for an automotive speed changer. The five-gear thrust washer is composed of a thrust washer and a stopping steel ball and is installed on an input shaft between a four-gear driving gear and a five-gear driving gear on the basis of unchanging the fundamental speed changer structure of the original automotive speed changer, thereby ensuring the five progressing gears of the speed changer to be arranged inside the casing body of the speed changer, thus not only the purpose for reducing the axial length of the speed changer is achieved, but also the defects of bad lubricating and cooling effects caused by the externally arranged five-gear gear pair of the speed changer are reasonably solved.
Description
Technical field:
The utility model patent relates to five grades of thrust washers of a kind of automotive transmission, belongs to the vehicle transmission technical field.
Background technique:
In existing automotive transmission, the following structural type of the general employing of five grades of manual transmissions of traditional preposition forerunner: at first behind the fourth gear driving gear, arrange the speed changer rear bearing, behind case of transmission, arrange five grades of gears, Five-gear synchronizer then, add bonnet at last.This automotive transmission, it is external to make five grades of gear pairs of speed changer be in transmission case, because the axial length of speed changer is longer, thereby it lubricates and cooling effect all has been subjected to bigger limitation.
Summary of the invention:
In view of the problem of above-mentioned existence, the purpose of this utility model provides five grades of thrust washers of automotive transmission of a kind of compact structure, lubricated and good cooling results.
The purpose of this utility model is achieved like this:
Five grades of thrust washers of automotive transmission described in the utility model, constituted by thrust washer, stop steel ball, it is on the basis of the basic drive mechanism that does not change original automotive transmission, be installed on the input shaft between fourth gear driving gear and the five grades of driving gears, thereby five gears that advance of speed changer are arranged in the case of transmission, so both reached and shortened the speed changer axial length, rationally solved that external and the lubricated and cooling effect that cause of five grades of gear pairs of speed changer is not good to wait not enough shortcoming simultaneously again.
Description of drawings
Fig. 1 is the structural layout plan of automotive transmission.
Fig. 2 is the H-H sectional view of Fig. 1.
Wherein: five grades of driving gear 10-of 1-stop steel ball 2-thrust washer 3-fourth gear driving gear 4-input shaft 5-three fourth gear synchronizer 6-snap ring 7-needle bearing 8-snap ring 9-needle bearing 11-Five-gear synchronizer
Embodiment:
Five grades of thrust washers of automotive transmission are made of thrust washer 2, stop steel ball 1, thrust washer 2 is installed on the input shaft 4 between fourth gear driving gear 3 and the five grades of driving gears 9, and stop steel ball 1 is installed in the circular groove of the input shaft 4 between fourth gear driving gear 3 and the five grades of driving gears 9.
During assembling, three fourth gear synchronizers 5, snap ring 6, needle bearing 7 and fourth gear driving gear 3 are installed successively, in the circular groove endoporus of input shaft 4, load onto stop steel ball 1, load onto five grades of thrust washers 2 in the circular groove, snap ring 8, needle bearing 10, five grades of driving gears 9, Five-gear synchronizer 11 etc. are installed then successively.Five grades of thrust washers have played the effect of axially locating shoulder block after being in place.Adopting stop steel ball 1 in five grades of thrust washers is in order to prevent relatively rotating of five grades of thrust washers and input shaft.
When fourth gear is worked, power through the input shaft spline reach three, the fourth gear synchromesh gear hub, three, the fourth gear synchronizer gear sleeve engages with the fourth gear driving gear, power is exported through the fourth gear driven gear.Fourth gear driving gear the right is adjacent with three fourth gear synchromesh gear hubs, and the left side is faced mutually with five grades of thrust washers, and this just makes the fourth gear driving gear have a rational axial clearance.The fourth gear driving gear can not drive five grades of driving gears and rotate, five grades of yet not therefore excessive wears of needle bearing.In five grades of whens work, the fourth gear needle bearing can excessive wear, is same reason yet.
Unique texture scheme by five grades of thrust washers of above employing, increased the rigidity of input shaft, improved assembly technology, five forward gearss of speed changer are arranged in the case of transmission, effectively improved the lubricated cooling effect of five grades of gear pairs of speed changer, and the later half housing of cancellation speed changer.
