Description
Technical field
The present invention relates to a kind of speed changer electric-controlled control device that is applicable to automated mechanical transmission (AMT), in particular, is a kind ofly to adopt single motor driving, silk to shoulder nut transmission and built-up gear rackwork to move the Effector that distributes.
Background technique
Automated mechanical transmission (AMT) technology is to increase gyropilot on the MT basis, replace the driver to finish clutch and select the manipulation of gear shift, because of its cost lower, care and maintenance is easy, the efficient height is beneficial to energy-saving and emission-reduction, has therefore occupied a part of transmission market.
Currently marketed AMT operating mechanism pattern is a lot, especially based on hydraulic control mechanism.The Effector that with the motor is actuator in recent years is because cost is low, and steady performance more and more obtains paying attention to.But it is in the existing motor driving operating mechanism, must the individual motor more than 2 handle, be unfavorable for the reliability of system like this, and obvious with respect to single motor manipulation inferior position on space, weight and cost.
The AMT operating mechanism mainly is clutch linkage, gear selecting operating mechanism and selector device.Be characterized in that each operating mechanism substantially all is alternation, the occasion that operating mechanism is worked simultaneously seldom, and can by control on take measures thoroughly to avoid this problem.This just provides prerequisite for the optimization of motor driving operating mechanism.
Summary of the invention
For solving the problem that prior art exists, the present invention proposes single electric control Effector of a kind of AMT of being applicable to, and it adopts a motor to finish gear selecting, shift control, can improve system reliability, structural compactness and saving cost.
The present invention is solved by the following technical programs:
Electric-controlled control device of automobile mechanical transmission, comprise that a built-up gear rackwork, includes the feed screw nut driving mechanism of leading screw and feed screw nut, tooth bar blocking element, also comprise a motor, its output shaft is connected with described leading screw, and small gear and described feed screw nut in the described built-up gear rackwork are hinged; Described built-up gear rackwork has 2 output tooth bars, and these 2 output tooth bars connect the gear selecting and the gearshift of automobile mechanical transmission respectively; Described tooth bar blocking element has 2, and it is respectively applied for the locking and the release of 2 output of control tooth bar.
Motor output shaft described in the present invention is connected by coupling with the leading screw of described screw-nut body.
Because adopt above technological scheme, the present invention finishes gear selecting, shift control by a motor, the quantity that it can reduce control motor in the AMT control system to greatest extent helps improving system reliability, structural compactness and saving cost.Its mechanism principle scheme is: adopt the feed screw nut transmission to realize slowing down to increase turning round, and rotatablely moving of motor become the straight line motion of nut.And then, realize the distribution and the control of motion by built-up gear rackwork and Teethed bolt lock locking apparatus.Adopt mechanism principle scheme of the present invention, cooperate rational controlling method, can effectively solve the electrically controlled manipulation problem of automobile mechanical transmission, simple and practical, the cost performance height.
Description of drawings
The present invention is described in detail below in conjunction with the drawings and specific embodiments:
Fig. 1 is a system architecture schematic diagram of the present invention.
Among the figure:
1 drive motor; 2 leading screws; 3 feed screw nuts; 4 small gears; 5 gear selecting tooth bar blocking elements; 6 gear selectings output tooth bar; 7 gear shift output tooth bar; 8 gear shift tooth bar blocking elements
Embodiment
The invention will be further described with reference to the accompanying drawings below:
As shown in Figure 1, a kind of electric-controlled control device of automobile mechanical transmission, comprise that a built-up gear rackwork, includes the feed screw nut driving mechanism of leading screw and feed screw nut, tooth bar blocking element, drive motor 1 is connected with the feed screw nut driving mechanism, and the small gear 4 in the built-up gear rackwork is hinged with feed screw nut 3.Therefore, described built-up gear rackwork has 2 degrees of freedom, and 2 output links can be arranged, and 2 tooth bars connect the gear selecting and the gearshift of automobile mechanical transmission respectively as output link (gear selecting output tooth bar 6 and gearshift output tooth bar 7); 2 tooth bar blocking elements (gear selecting Teethed bolt lock locking apparatus 5 and gear shift Teethed bolt lock locking apparatus 8) are respectively applied for the locking or the release of 2 output of control tooth bar.Like this,, the output torque of single motor can be distributed to selectively certain 1 in 2 output tooth bars, thereby be realized only with 1 Electric Machine Control gear selecting or gearshift action by locking or the release of handling 2 tooth bar blocking elements.
Further specify working principle of the present invention below in conjunction with accompanying drawing 1: the output shaft of motor 1 can be connected by coupling with leading screw 2, by the feed screw nut driving mechanism rotatablely moving of leading screw 2 is converted into the straight line motion of feed screw nut 3, but a stationary axle on the small gear 4 wrapping wire thick stick nuts rotates.Like this, small gear 4 both can be done straight line motion with feed screw nut 3, can rotate around central axis again, and small gear 4 can drive gear selecting output tooth bar 6 or gearshift output tooth bar 7 moving linearlies.2 blocking elements (gear selecting tooth bar blocking element 5, gearshift tooth bar blocking element 8) are controlled the locking or the release of gear selecting output tooth bar 6 and gear shift output tooth bar 7 respectively.In closed 2 blocking elements any 1 with 1 degrees of freedom of constraint mechanism, thereby makes mechanism become single motor-driven mechanism with single degree of freedom, well-determined drive connection between realizing input and exporting.
(1) if with gear selecting tooth bar blocking element 5 gear selecting is exported tooth bar 6 lockings, then the motion of feed screw nut 3 will be delivered to gearshift output tooth bar 7 by small gear 4.
(2) if export tooth bar 7 with the 8 locking gear shift of gearshift tooth bar blocking element, then the motion of feed screw nut 3 will be delivered to block selecting output tooth bar 6 by small gear 4.
Like this, switching controls by 2 blocking elements 5,8, realize only controlling respectively the purpose of different output tooth bar 6,7 characteristics of motion with single motor 1, thereby reduce the quantity of control motor in the AMT control system to greatest extent, help improving system reliability, structural compactness and saving cost.
Certainly, any time, an output tooth bar release and output movement can only be arranged, the degrees of freedom that promptly remains the built-up gear rackwork in the working procedure is 1.
But above-mentioned embodiment is exemplary, is to be the restriction that this patent is comprised scope in order better to make those skilled in the art can understand this patent, can not to be interpreted as; So long as according to spirit that this patent discloses done anyly be equal to change or modify, all fall into the scope that this patent comprises.
