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
This technology 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 one and selects engage a gear axle, and this selects on engage a gear axle and is fixed with shifting gear, and shifting gear engages with the engage a gear power gear on engage a gear motor output shaft.When engage a gear motor action, driven by gear transmission and select engage a gear axle to rotate, realize engage a gear.
Select on engage a gear axle and also have around the annular tooth selecting engage a gear axle (being equivalent to gear selecting tooth), annular tooth engages with the gear selecting power gear on step electric machine output shaft.When gear selecting motor action, by engaging of annular tooth and gear selecting power gear, drive and select engage a gear axle to move to diverse location vertically, realize gear selecting.
Certainly, select on engage a gear axle and be also fixed with gear selecting positioning block, gear selecting positioning block is arranged three grooves coordinated with the end of gear selecting locating stud, locating stud can along the radial expansion of shift selection shaft.Select engage a gear axle to move to diverse location vertically, gear selecting locating stud is just in time positioned at different grooves, reliably realizes the axially locating selecting engage a gear axle.
The shortcoming of existing gearshift.
The gear selecting tooth coordinated with gear selecting power gear selects engage a gear axle to rotate, moves axially again, so can only be the annular tooth around selecting engage a gear axle.This causes the contact of gear selecting power gear and annular tooth to be point cantact, so annular tooth is stressed comparatively large, easily wearing and tearing and damage, reduce the working life of gearshift.
In addition, in gear mechanism, be the ordinary gear drive mechanism of shifting gear and engage a gear power gear, ordinary gear drive mechanism can not realize self-locking, this may (such as vibrate) cause shifting gear and engage a gear power gear mutually to be rotated because of various reasons, makes to select engage a gear axle rotation and out of supply.
Summary of the invention
The object of this technology is to provide a kind of gearshift that is little, long service life that weares and teares.
This gearshift, comprises coaxial shift selection shaft and engage a gear axle, is connected between shift selection shaft with engage a gear axle with revolute pair; Shift selection shaft is provided with tooth bar, tooth bar with for engaging along the gear selecting power gear in the gear selecting power mechanism of shift selection shaft axis movement with carry-over bar; Engage a gear axle is connected with the engage a gear power mechanism driving engage a gear axle to rotate.
The beneficial effect of this technology: one of prior art is selected engage a gear axle to change over two coaxial shift selection shafts and engage a gear axle by this technology, and is connected with revolute pair between shift selection shaft with engage a gear axle.Like this, when engage a gear, engage a gear power mechanism drives engage a gear axle to rotate, but shift selection shaft does not rotate.(when engage a gear axle rotates, shift selection shaft does not rotate) tooth bar like this, engages with gear selecting power gear although arrange tooth bar, because, without the need to rotating, can not hinder the rotation of engage a gear axle.Meanwhile, owing to being that tooth bar engages with gear selecting power gear, both are linear contact lay, and the power in unit area is less, and tooth bar and gear selecting power gear are are all worn and torn less, long service life.
Above-mentioned gearshift, engage a gear power mechanism comprise the worm gear be fixed on engage a gear axle, with the worm screw of worm gear.This worm-and-wheel gear has auto-lock function, and that is, can only be that worm screw drives worm gear wheel, worm gear cannot drive worm screw to rotate, so, can effectively prevent engage a gear axle from rotating under a variety of causes and out of supply.Preferably, engage a gear power mechanism also comprises engage a gear motor; The output shaft of worm screw and engage a gear motor is fixedly linked.
Above-mentioned gearshift, gear selecting power mechanism also comprises the step electric machine driving gear selecting power gear to rotate.
Above-mentioned gearshift, comprises the gear selecting positioning block be fixed on shift selection shaft, and gear selecting positioning block is arranged the plural groove coordinated with the end of gear selecting locating stud, gear selecting locating stud can along the radial expansion of shift selection shaft.Gear selecting positioning block, gear selecting locating stud etc. belong to prior art, are not described in detail.Preferably, the tooth bar back side that is positioned at of gear selecting positioning block.Like this, the length of shift selection shaft can be shortened.

Embodiment
See the gearshift shown in Fig. 1,2, comprise coaxial shift selection shaft 1 and engage a gear axle 2, gear selecting power mechanism 3, engage a gear power mechanism 4, gear selecting positioning means 5 etc.
One end of shift selection shaft 1 has step hole 11, and one end of engage a gear axle 2 arranges Step Shaft 21, and Step Shaft 21 extend in step hole 11, and making between shift selection shaft and engage a gear axle can coaxial rotation mutually.
Gear selecting power mechanism 3 comprises tooth bar 31, gear selecting power gear 32, gear shaft 34, step electric machine 33, driving gear 35, driving gear 36.
Engage a gear power mechanism 4 comprises worm gear 41, the worm screw 42 with worm gear, engage a gear motor 43.
Gear selecting positioning means 5 comprises gear selecting positioning block 51, gear selecting locating stud 52 etc.
Shift selection shaft 1 is provided with gear selecting positioning block 51 and tooth bar 31, the tooth bar back side that gear selecting positioning block is positioned at.Gear selecting positioning block 51 is arranged three grooves 511 coordinated with the end of gear selecting locating stud.Gear selecting locating stud can along the radial expansion of shift selection shaft.
Tooth bar 31 engages with gear selecting power gear 32; Gear selecting power gear is fixed on gear shaft 34, and the driving gear 35 of gear shaft 34 engages with the driving gear 36 on the output shaft of step electric machine.
Worm gear 41 is fixed on engage a gear axle 2.Worm gear coordinates with worm screw.The output shaft of worm screw and engage a gear motor is fixedly linked.
