Description
Technical field
The present invention relates to the variable transmission mechanisms of automobile.
Background technique
Publication No. is that the application for a patent for invention of CN108730429A discloses a kind of three class gear shift device comprising input
Axis, output shaft and jackshaft, input shaft and output shaft coaxial line, the inner end of output shaft are protruded into the stomidium of input shaft inner end, can
It is rotationally supported at the inner end of input shaft；It is set with first gear and third gear on input shaft, is fixed with the 5th on output shaft
Gear is set with second, the four, the 6th gears on jackshaft, and second gear is often engaged with first gear, the 4th gear and third
Gear often engages, and the 6th gear is often engaged with the 5th gear.Although this kind three keeps off the more other three class gear shift devices of speed change gear
Structure is simpler, but it still has the disadvantage that one, has this three axis of input shaft, output shaft and jackshaft, axis part
It is more；Two, input shaft and output shaft are located on same axis, keep three gear speed change gears larger in axial size, lead to three gears
Speed change gear overall volume is larger；Three, output shaft inner end is pivotally supported at the inner end of input shaft, not only input shaft and output
The inner end of axis needs the bearing of a rotatable engagement, and due to being cantilever support, in order to improve the rigidity of output shaft, prevents it
Moving is generated, two bearings must be at least installed in output shaft outer end, this kind of structural strength is lower, and manufacturing cost is higher；Four, should
One of gear (the second gear) revolving speed of three gear speed change gears can only be transmitted by 1:1, smaller in revolving speed matching range.
Summary of the invention
The object of the present invention is to provide one kind three to keep off variable transmission mechanism, to advanced optimize its structure and performance.
Three gears variable transmission mechanism of the present invention, including the input shaft and output shaft being parallel to each other, on input shaft
It is set with first gear, second gear and third gear, second gear is by spline and inputs axis connection, first gear and third
Gear empty set is located at and on input shaft close to the both ends of second gear, the inner face and third tooth of first gear
The inner face of wheel is provided with the internal tooth that can be engaged with second gear.
The 4th gear, the 5th gear and the 6th gear are set on output shaft, the 5th gear empty set is on input shaft, and
Four gears and the 6th gear are connected with exporting axis by spline, are located at and close to the both ends of the 5th gear, the 5th gear
The end face of one end close to the 6th gear is provided with the internal tooth that can be engaged with the 6th gear.
First gear is often engaged with the 4th gear, and second gear is often engaged with the 5th gear, third gear and the 6th gear
Often engagement, circumferentially offers fork slot in second gear and the 6th gear.
Three gears variable transmission mechanism of the present invention only has one to merely enter axis and an output shaft, relative to
The three class gear shift device of CN108730429A reduces jackshaft and one and is served only for input shaft and output shaft rotatable engagement
Bearing.Since input shaft and output shaft are parallel to each other, not on the same axis, so that three gear variable transmission mechanisms are in the axial direction
Size it is relatively small, the overall volume of three gear variable transmission mechanisms can be reduced to a certain degree, while there is good structure
Intensity and lower manufacturing cost.The non-revolving speed by 1:1 of three gears of the three gears variable transmission mechanism transmits, therefore revolving speed
Three class gear shift device with range compared with CN108730429A is big.
Detailed description of the invention
Fig. 1 is structural schematic diagram when three gears variable transmission mechanism of the present invention is in neutral position state.
Specific embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1, the three gears variable transmission mechanism includes the input shaft 10 and output shaft 5 being parallel to each other, in input shaft
First gear 6, second gear 7 and third gear 9 are set on 10, wherein second gear 7 is connect by spline with input shaft 10,
Fork slot 8 is circumferentially offered in second gear 7.First gear 6 and 9 empty set of third gear are on input shaft 10, difference
Positioned at the both ends of simultaneously close second gear 7, internal tooth is set in the inner face of first gear 6 and the inner face of third gear 9, when
After stirring second gear 7 to the direction of first gear 6, second gear 7 is in the state of keeping connecting with 10 spline of input shaft, energy
Enough interior tooth engagements with first gear 6 simultaneously；After stirring second gear 7 to the direction of third gear 9, second gear 7 is being protected
It holds in the state of being connect with 10 spline of input shaft, it being capable of interior tooth engagement with third gear 9 simultaneously.
The 4th gear 4, the 5th gear 3 and the 6th gear 1 are set on output shaft 5, wherein 3 empty set of the 5th gear is defeated
On shaft 5, fork slot 2 is circumferentially offered on the 6th gear 1.4th gear 4 and the 6th gear 1 pass through spline and output shaft
5 connections, are located at and the both ends of close 5th gear 3, the 5th gear 3 are set in the end face of one end close to the 6th gear 1

First gear 6 and the 4th tooth 4 take turns it is normal engage, second gear 7 is often engaged with the 5th gear 3, third gear 9 and the 6th
Gear 1 often engages.
The three gears variable transmission mechanism can be realized the transformation of three gears, its working principle is that (using neutral gear position as
Beginning state):
One, the 6th gear 1 is stirred to 3 direction of the 5th gear, the state for connecting the 6th gear 1 with 5 spline of output shaft in holding
The lower interior tooth engagement with the 5th gear 3, second gear 7 and 10 synchronous rotary of input shaft, second gear 7 drive the rotation of the 5th gear 3
Turn, the 5th gear 3 drives output shaft 5 to rotate by the 6th gear 1, completes the transmitting of first gear.
Two, second gear 7 is stirred to 6 direction of first gear, connect second gear 7 with 10 spline of input shaft in holding
With the interior tooth engagement of first gear 6 under state, first gear 6 passes through the by second gear 7 and 10 synchronous rotary of input shaft
Four gears 4 drive output shaft 5 to rotate, and complete the transmitting of second gear.
Three, second gear 7 is stirred to 9 direction of third gear, connect second gear 7 with 10 spline of input shaft in holding
With the interior tooth engagement of third gear 9 under state, third gear 9 passes through the by second gear 7 and 10 synchronous rotary of input shaft
Six gears 1 drive output shaft 5 to rotate, and complete the transmitting of third gear.
