Abstract
The invention discloses a gear selecting/shifting control device of a vehicle transmission, which comprises a housing, a cam shaft, a gear shifting part, a gear shifting fork, a shifting block and a gear shifting motor, and a gear selecting motor, wherein output shafts of two motors are respectively connected with the cam shaft and the gear shifting part. The cam shaft is connected with an output shaft of the gear selecting motor through a coupler or a tightening sleeve. The gear shifting part is connected with the gear shifting motor through a swinging arm or a gear and rack mechanism, and the gear shifting part is connected with the housing. The invention has the advantages that two shifting fork shafts are reduced in structure, one shifting fork shaft is only adopted, thus the gear is shifted through axial movement, and a function of the shifting fork shafts can be obtained; and the gear can be flexibly selected through controlling the angle for which the cam shaft rotates.
Description
Technical field
The present invention relates to a kind of automotive transmission, particularly a kind of automotive transmission choosing/shift operating device.
Background technique
Automatic mechanical transmission generally adopts the electrolyte type Effector, but its complex structure, volume is big, action response is slow.And adopt motor shift control system to have simple relatively, the lightweight advantage of structure, and being easy to control, precision is higher.Drive in the operating mechanism in prior motor; 2 of general employings or plural motor select shift control, and like the scheme of 3 motors of patent CN1635289 employing, but this scheme has not only increased the volume and weight of operating mechanism; And improved cost, be unfavorable for the marketization.The scheme that adopts single motor is also arranged simultaneously, adopt the technological scheme of motor and cam mechanism such as patent CN2323999, but because the cam curve restriction can not be got over gear shift, can only carry out the order gear shift, shift time is long.The gearshift scheme of selecting general speed changer all adopts three declutch shift shafts, and can not select shift sequence flexibly.
Summary of the invention
Technical problem to be solved by this invention will provide a kind of Dual-motors Driving that adopts, and only adopts a declutch shift shaft, can select gearshift order automotive transmission choosing/shift operating device flexibly.
In order to solve above technical problem; The invention provides a kind of automotive transmission choosing/shift operating device; This device comprises housing, camshaft, shift component, selector fork, shifting block and shift motor, choosing shelves motor, and the output shaft of two motors is connected with camshaft with shift component respectively.
Said camshaft is connected through coupling or tensioner cover with choosing shelves motor output shaft.
Said shift component is connected through swing arm or pinion and rack with gear shifting motor, and shift component is connected with housing.
Said shift component and selector fork corresponding position are provided with along the choosing shelves hole of the cross-sectional circumferential several angle distribution of axle, get into or withdraw from choosing shelves hole by shifting block and realize the gear selection.
Working principle of the present invention: changing fourth gear with second gear is example.The initial gear of speed changer is a neutral gear, and after receiving second gear and selecting shift signal, a controller control choosing shelves motor driving camshaft rotates corresponding angle, promotes the choosing shelves hole that shifting block gets into the second gear selector fork, and selector fork and shift component are connect, and realizes choosing grade; Move axially through the gear shifting motor drive shift member again, the selector fork with its connection is moved, realize gear shift.When second gear changes fourth gear; Move through the gearshift component axial earlier and return neutral; Camshaft rotates respective angles again, at this moment withdraws from from choosing shelves hole with the corresponding shifting block of second gear, simultaneously with the rotation of the corresponding shifting block of fourth gear along with camshaft; Get in the choosing shelves hole of fourth gear selector fork, thereby get into this gearshift procedure.Selector fork moves axially, and two shift patterns and a neutral position are arranged.Whole gearshift procedure guarantees that by self-locking device (not drawing among the figure) each selector fork is fixed on the relevant position, does not squint.
Superior effect of the present invention is:
1) the present invention has adopted the gearshift parts that support stiffness is good, and it both can realize gearshift through moving axially, and can play the effect of declutch shift shaft again.Therefore, compare with the general shifting operating device that selects, the present invention structurally is equivalent to reduce two declutch shift shafts, only adopts a declutch shift shaft, and is simple in structure, compact;
2) can select gear flexibly through the angle that the control camshaft turns over, when self-locking device can guarantee work in the gearshift procedure do not squint in the position of each selector fork.

Embodiment
See also shown in the accompanying drawing, the present invention is done to describe further.
As depicted in figs. 1 and 2; The invention provides a kind of automotive transmission choosing/shift operating device; This device comprises that the output shaft of housing 1, camshaft 2, shift component 3, selector fork 4, shifting block 5 and shift motor 7,8, two motors of choosing shelves motor is connected with camshaft 2 with shift component 3 respectively.
Said camshaft 2 is connected through coupling 10 or tensioner cover with choosing shelves motor 8 output shafts.
Said shift component 3 is connected through swing arm 9 or pinion and rack with gear shifting motor 7, and shift component 3 is connected with housing 1.
Said shift component 3 and selector fork 4 corresponding positions are provided with along the choosing shelves hole 6 of the cross-sectional circumferential several angle distribution of axle, get into or withdraw from choosing shelves hole 6 by shifting block 5 and realize the gear selection.
Working principle of the present invention: changing fourth gear with second gear is example.The initial gear of speed changer is a neutral gear, and after receiving second gear and selecting shift signal, controller control choosing shelves motor 8 drive cam shaft 2 are rotated corresponding angle, promote the choosing shelves hole that shifting block 5 gets into the second gear selector forks, and selector fork and shift component 3 are connect, and realizes choosing grade; Move axially through gear shifting motor 7 drive shift member 2 again, the selector fork with its connection is moved, realize gear shift.When second gear changes fourth gear; Move through the gearshift component axial earlier and return neutral, camshaft rotates respective angles again, at this moment withdraws from from choosing shelves hole with the corresponding shifting block of second gear; Get in the choosing shelves hole of fourth gear selector fork with the corresponding shifting block of fourth gear simultaneously, thereby get into this gearshift procedure.Selector fork moves axially, and two shift patterns and a neutral position are arranged.Whole gearshift procedure guarantees that by self-locking device (not drawing among the figure) each selector fork is fixed on the relevant position, does not squint.
Can adopt swing arm 9 to realize transmission of movement between gear shifting motor 7 and the shift component 3.Can adopt connections such as coupling 10 between choosing shelves motor 8 and the camshaft 2.
