Abstract
The utility model provides an autocontrol device for automotive clutch comprising a shell, a roller rotating transmission mechanism, an output mechanism, a sensor, and a motor. A displacement parameter of a clutch stayguy is collected by the sensor and conveyed to an ECU which analyzes the definite condition of a car according to the displacement parameter and other signal parameters of the car and drives the motor connected with the ECU to rotate. The motor drives the roller rotating transmission mechanism to rotate and transforms a rotating power to a linear power to the output mechanism and provides an impetus of the clutch stayguy to draw the automotive clutch to joint and to separate. The sensor conveys the real-time displacement parameter of the clutch stayguy to the ECU to realize the autocontrol of clutch. The utility model has the advantages of simple conformation, lower manufacturing cost, and high reliability, or the like to make a popularity of the autocontrol device for automotive clutch equipped in motor vehicle field become possible.

Figure one is a fundamental diagram of the present utility model.
Figure two is structure master's sectional views of the utility model embodiment.
Figure three is the right sectional views of the utility model embodiment's structure.
(5) embodiment
Referring to figure one, the utility model is by housing 101, and roller screw-drive mechanism 120 goes out force mechanisms 110, and sensor 102 and motor 140 are formed.
Referring to Fig. 2 and Fig. 3.
Roller screw-drive mechanism 120 comprises 122, one roller framves 123 of 121, three thread-shaped rollers of a thread spindle and two roller overcoats 124.
The output shaft 141 of motor 140 is connected with thread spindle 121.
In order to make motor output shaft 141 and thread spindle 121 smooth operations, a crosshead shoe shaft joint 104 can be set between it.
Three thread-shaped rollers 122 are installed on the roller frame 123 with thread spindle 121 engagements and to be hexagonal angle around 121 on screw thread circumferentially evenly distributed, between two roller overcoats 124 elastic element 125 is housed, and be enclosed within outside three thread-shaped rollers 122, roller overcoat 124 is provided with the slotted eye 124a that is connected with the finger 116a that goes out on the shift fork 116 of exerting oneself in the force mechanisms 110, the internal surface of the interior tooth of thread-shaped roller 122 respectively with the raceway engagement of roller overcoat 124.
Elastic element 125 is a shell fragment.Also can adopt helical spring or rubber or other elastic material.
The screw thread two ends of thread spindle 121 are separately installed with position limit pin 126 in order to limit thread-shaped roller 122, roller frame 123 and roller overcoat 124 in axial displacement, make it be no more than the limit.
Go out force mechanisms 110 and comprise the shift fork 116 of exerting oneself, slide plate 115, bearing 114, axle 113, slide rail 112, loam cake 111, sensor finger 117 and sensor shift fork 118.
But an end of slide plate 115 is offered the slotted eye 115a of fixed clutch backguy 103, and the termination 103a of clutch cable 103 is placed in the slotted eye 115a.Therefore be convenient to install and fix clutch cable 103 and termination 103a, can spur clutch cable 103 when slide plate 115 moves.
In order to prevent that termination 103a from coming off from slotted eye 105a, a backing pin 119 can be set at the edge of slotted eye 105a.
When thread spindle 121 during by motor 140 rotary driving, the restriction of shift fork 116 can not be rotated because roller overcoat 124 is exerted oneself, can only on thread spindle 121, axially move along with going out force mechanisms 110, therefore thread-shaped roller 122 is being rolled on the thread groove of thread spindle 121 and on the raceway of roller product overcoat 124 under the restriction of circumferencial direction by roller stand 123, therefore drive roller overcoat 124 and move vertically, and on slide rail 112, do straight-line displacement by the shift fork 116 drive slide plates 115 of exerting oneself.
More than be an embodiment of the present utility model.
Going out force mechanisms can be that symmetry plane is provided with the axle head that two pull bars stretch out the roller screw-drive mechanism respectively in roller overcoat both sides with the axle center at the roller screw-drive mechanism also, its advantage is to have reduced above embodiment to go out force mechanisms in a side of roller screw-drive mechanism and the sliding-frictional resistance that the moment of flexure that produces is increasing in the mechanism (mode that adds raceway by bearing in above embodiment is alleviated), and shortcoming is that the axial dimension of device is bigger.
