Abstract

The invention provides a gear shift device with low wear degree and long service life. The gear shift device comprises a gear selection shaft and a gear shift shaft which are coaxial and connected with each other through a revolute pair, wherein a rack is arranged on the gear selection shaft and meshed with a gear selection power gear which is used for driving the rack to move along the axis of the gear selection shaft and positioned in a gear selection power mechanism; and the gear shift shaft is connected with a gear shift power mechanism for driving the gear shift shaft to rotate.

Description

Gearshift
Technical field
Present technique relates to gearshift, specifically, is a kind of gearshift of automatic gearbox of vehicles.
Background technique
At present, the gearshift of automatic gearbox of vehicles comprises that is selected an engage a gear axle, and this selects and is fixed with the engage a gear gear on the engage a gear axle, the engage a gear power gear engagement on engage a gear gear and the engage a gear motor output shaft.When the engage a gear motor action, select the engage a gear axle to rotate through the gear transmission drive, realize engage a gear.
Select and also have on the engage a gear axle around the annular tooth of selecting the engage a gear axle (being equivalent to choosing shelves tooth), annular tooth and the choosing shelves power gear engagement of selecting on the shelves motor output shaft.Elected shelves motor action through the engagement of annular tooth with choosing shelves power gear, drives and selects the engage a gear axle to move to diverse location vertically, realizes the choosing shelves.
Certainly, select and also be fixed with choosing shelves positioning block on the engage a gear axle, three grooves that cooperate with the end of choosing shelves locating stud are set on the choosing shelves positioning block, locating stud can be along the radial expansion of shift selection shaft.Select the engage a gear axle to move to diverse location vertically, choosing shelves locating stud just in time is positioned at different recesses, reliably realizes selecting the axially locating of engage a gear axle.
The shortcoming of existing gearshift.
The choosing shelves tooth that cooperates with choosing shelves power gear selects the engage a gear axle to rotate, moves axially again, so can only be around the annular tooth of selecting the engage a gear axle.This causes selecting grade power gear is the some contact with contacting of annular tooth, so annular tooth is stressed bigger, and easy abrasion and damage, the working life of having reduced gearshift.
In addition; In the engage a gear mechanism, be the ordinary gear drive mechanism of engage a gear gear and engage a gear power gear, the ordinary gear drive mechanism can not be realized self-locking; This may be because of various reasons, and (for example vibration) causes engage a gear gear and engage a gear power gear to be rotated each other, makes to select the rotation of engage a gear axle and out of supply.
Summary of the invention
The purpose of present technique provides a kind of gearshift little, long service life that weares and teares.
This gearshift comprises coaxial shift selection shaft and engage a gear axle, links to each other with revolute pair between shift selection shaft and the engage a gear axle; Shift selection shaft is provided with tooth bar, tooth bar and the choosing shelves power gear engagement that is used for driving the choosing shelves power mechanism that tooth bar moves along the shift selection shaft axis; The engage a gear axle links to each other with the engage a gear power mechanism that drives the rotation of engage a gear axle.
The beneficial effect of present technique: present technique selects the engage a gear axle to change over two coaxial shift selection shafts and engage a gear axle one of existing technology, and links to each other with revolute pair between shift selection shaft and the engage a gear axle.Like this, when engage a gear, the engage a gear power mechanism drives the engage a gear axle and rotates, but shift selection shaft does not rotate.Like this, though tooth bar and the engagement of choosing shelves power gear are set, because (shift selection shaft did not rotate when the engage a gear axle rotated) tooth bar need not to rotate, and can not hinder the rotation of engage a gear axle.Simultaneously, owing to be tooth bar and the engagement of choosing shelves power gear, both are line contacts, and the power on the unit area is less, and a tooth bar and a choosing shelves power gear are are all worn and torn less, long service life.
Above-mentioned gearshift, engage a gear power mechanism comprise the worm gear that is fixed on the engage a gear axle, the worm screw that cooperates with worm gear.This worm-and-wheel gear has auto-lock function, that is to say, can only be that worm screw drives worm gear and rotates, and worm gear can't drive worm screw and rotate, so, can prevent effectively that the engage a gear axle from rotating and out of supply under a variety of causes.Preferably, the engage a gear power mechanism also comprises the engage a gear motor; The output shaft of worm screw and engage a gear motor is fixedly linked.
Above-mentioned gearshift, choosing shelves power mechanism also comprise the choosing shelves motor that drive choosing shelves power gear is rotated.
Above-mentioned gearshift comprises the choosing shelves positioning block that is fixed on the shift selection shaft, and the plural groove that cooperates with the end of choosing shelves locating stud is set on the choosing shelves positioning block, and choosing shelves locating stud can be along the radial expansion of shift selection shaft.Choosing shelves positioning block, choosing shelves locating stud etc. belong to existing technology, are not described in detail.Preferably, the tooth bar back side of selecting the shelves positioning block to be positioned at.Like this, can shorten the length of shift selection shaft.
