(57) Abstract:

Usage: in industry, in particular in vehicles. The inventive control mechanism coupling the vehicle contains the lever 1, the middle part of which enters a groove of a support 2 mounted on the crankcase 3. Sleeve 4 mounted on the rail 5, is connected with the lever 1 through the hinge 6. In the middle part of the lever 1 has a groove 7 in which the axis 8 has a bearing 9. The lever 1 outer bearing ring 9 rests on the surface 10 of the support 2, whose cross section in the plane of operation of the lever passing through the axis of rotation of the clutch 11, curve, concave part directed to the bearing of the lever 9. The surface 10 of the support 2 may have a cross section in the plane of operation of the lever arc, the chord of which is inclined to the axis of rotation of the clutch 11. The surface 10 of the support 2 may be performed on the liner. The curve in the cross section of the surface 10, the magnitude of the radius of the arc and the angle of the chord are selected from the condition of providing the necessary stroke and the desired position of the lever 1. 2 C.p. f-crystals, 3 ill.

The invention relates to mechanical engineering and can be used in vehicles.

Famous design is the end of the articulated with the sleeve installed on the rail, and relies on the support arm through the bearing for movement of the lever relative to the support.

The disadvantage of this design is the lack of range of a possible increase in force on the bushing with a limited amount of force on the pedals when turning off the clutch.

The purpose of the invention is to reduce the effort of managing traction while maintaining the General direction of the clutch pedal.

This goal is achieved by the fact that the control mechanism coupling the vehicle includes a lever connected at one end with a pedal-parts of the actuator, the other end articulated with the sleeve installed on the rail, and relies on the support arm through the bearing for movement of the lever relative to the support. Work surface support arm has a cross section in the plane of operation of the lever passing through the axis of rotation of the clutch, a curve, concave part directed to the support bearing of the lever. The surface can be performed on the liner and having in cross-section in the plane of operation of the lever arc, the chord of which is inclined to the axis of rotation of the clutch.

Sleeve 4 mounted on the rail 5, is connected with the lever 1 through the hinge 6. In the middle part of the lever 1 has a groove 7 in which the axis 8 has a bearing 9. The lever 1 outer bearing ring 9 rests on the surface 10 of the support 2, whose cross section in the plane of operation of the lever passing through the axis of rotation of the clutch 11 is a curve, concave part directed to the bearing of the lever 9. The surface 10 of the support 2 may have a cross section in the plane of the operating lever arch 12, chord 13 which is inclined to the axis of rotation of the clutch 11. Surface 10 (Fig.3) support 2 may be performed on the liner 14. The curve in the cross section of the surface 10, the magnitude of the radius of the arc 12 and the angle of the chord 13 is selected from the conditions of providing the necessary stroke and the desired position of the lever 1.

When the control grip end of the lever 1 through the hinges 6 and moves the sleeve 4 along the guide 5. The middle part of the lever 1 is moved in the groove of a support 2 mounted on the casing 3 and the outer ring of the bearing 9 is rolled over the surface 10 of the support groove 2.
