Speed changer is can fix or stepping changes the gear drive of output shaft and input shaft velocity ratio, and it is comprised of driving mechanism and gear.Take five speed transmission as example, be set with the gear of five different numbers of teeth on the output shaft, output shaft gear and the corresponding engagement of each shifting gear on jack shaft or the input shaft, when automobile is in neutral gear, output shaft gear all rotates with the rotating speed that clutch spreads out of, but because the output shaft gear empty set on output shaft, does not rotate output shaft; When driver's engage a gear, reverse shift fork can promote some synchronizers and engage with output shaft gear, wherein, synchronizer by spline joint on output shaft, when synchronizer with after output shaft gear engages just with transmission of power to output shaft, realize engage a gear.
Owing to having high-grade gear and low-grade high torque gear at output shaft, this just needs output shaft to satisfy following the requirement: 1, the output shaft gear needs of empty set on output shaft and output shaft have lubricatedly preferably, that is to say to be provided with oil passageway and can be with oil delivery to the surface of contact of output shaft gear and output shaft on the output shaft; 2, the high torque (HT) gear on the output shaft requires output shaft that certain intensity need to be arranged, and also just needs suitable material and the larger diameter of axle; 3, output shaft is often understood High Rotation Speed, particularly during galloping, so output shaft should have preferably heat radiation, to prevent the axis body scaling loss.
Present automotive transmission output shaft is generally a Step Shaft, successively sheathed each grade driving gear and synchronizer on Step Shaft, yet owing to lacking effective radiating structure on this kind Step Shaft, so that the long-term work in the hot environment that is in of output shaft, this will have a strong impact on the working life of output shaft.
Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, has proposed a kind of automotive transmission output shaft, and this automotive transmission output shaft can effectively reduce the temperature of self in the course of the work, thereby has improved the working life of self.
The purpose of this utility model can realize by following technical proposal: a kind of automotive transmission output shaft, comprise a Step Shaft shape body, have successively on the described body for the stepped part one and the stepped part two that is connected fourth gear that connect five grades of gears, it is characterized in that, axially offer an oil through on the described body, radially offer respectively the oil-through hole that is connected with above-mentioned oil through on described stepped part one and the stepped part two, this oil-through hole is respectively oil-through hole one and oil-through hole two, and described oil-through hole one and oil-through hole two radially run through respectively above-mentioned body.
Body and stepped part one and stepped part two are one-body molded, and be slight to improve whole machinery.Five grades of gears and fourth gear are set in respectively on stepped part one and the stepped part two, not with synchronizer in conjunction with the time do not rotate with output shaft.Oil through is along body shaft to the middle part of offering and be positioned at body, and machine oil is along oil through and enter oil-through hole, by flowing of machine oil output shaft is played cooling effect.
Also have on the described body for the stepped part three and the stepped part four that is connected connecting intermediate gear that connect three-range transmission, between stepped part one and stepped part two, have be used to the spline one that is connected synchronizer, between stepped part two and stepped part three, have be used to the spline two that is connected synchronizer, between stepped part three and stepped part four, have be used to the spline three that is connected synchronizer.Body and stepped part three and joint four are one-body molded, improve mechanical strength.Synchronizer matches with spline, can rotate with output shaft, when one of them synchronizer when the gear on the output shaft is combined, this gear rotates with output shaft.
The diameter of described stepped part two is greater than the diameter of stepped part three, and the diameter of stepped part three is greater than the diameter of stepped part four.Make things convenient for gear to be installed on the output shaft successively.
Described body also has a helical gear in stepped part one away from an end of spline one.
Compared with prior art, this automotive transmission output shaft has the following advantages:
1, owing to having oil through and oil-through hole on the output shaft, the machine oil in the hole can effectively reduce the problem of output shaft, improves the working life of output shaft.
2, because the step on the output shaft and spline and body are all one-body molded, so the overall mechanical strength of output shaft is higher.
