Abstract

The invention relates to the field of transport engineering, in particular, to mechanisms for remote control of the gearboxes of self-propelled machines such as tractors, automobiles, combines, etc. The purpose of the invention is to facilitate control when expanding the range of gears. The remote control mechanism of the vehicle's gearbox contains sliders 2, installed with the possibility of linear movement relative to the body 1, mounted for rotation and linear movement relative to the body 1, and interacting with the holes 3 of the sliders 2 by means of a leash 4, the rod 5 with stops 6, rotatable relative to the body 1 and a coaxial rod 5, a support 7 and a control lever 8 with a handle 9 at one end 10. A rod 5 and a support 7 are fixed against relative rotation with the possibility of axial movement of the other end 19 of the control lever 8 with the stops 6 of the rod 5 is made as an additional lever 16 mounted on an axis relative to the support 7 by means of a lead 17 connected with the stops 6 of the rod 5 and through the groove 18 with the end 19 of the lever 8 control, while the control lever is provided with bounding arm 20 connected to support 7, which ensures its longitudinal movement along the groove 18 of the additional lever 16 and transverse movement for interaction with the side surfaces of the groove 18 of the additional frame chaga. 3 il.

7 of the additional lever 16, through a driver 17 connected to the stops 6 of the stem 5 n by means of a groove 18 - with the end 19 of the control lever 8, and the control lever is provided with a restriction connected with the support 7. The invention relates to transport engineering, in particular, to remote control mechanisms gearboxes of self-propelled machines such as tractors, cars, combines, etc.

The purpose of the invention is to facilitate control when expanding the range of shifting gears.

FIG. schematically shows the proposed mechanism; in fig. 2 - restrictive drawstring; in fig. 3 - additional lever.

The remote control mechanism of the vehicle gearbox contains sliders 2 gears mounted for linear movement relative to body 1, gears mounted for rotation and linear movement relative to the body and interacting with holes 3 of sliders 2 by means of a driver A, rod 5 with stops 6, pivoting relative to the housing 1 and bearing 7 supporting the rod 5 and the control lever 8 with the handle 9 at the end 10, mounted by the middle part 11 on the hinge 12 in the bearing 7. The rod 5 and the bearing 7 are fixed against rotation with the possibility of relative axial movement, for example, by means of a key 13 and a groove 14, in the support 7 an additional lever 16 is mounted on the axis 15, connected with stops 6 of the rod 5 by means of a driver 17 and interacting with the end 19 by means of a groove 18 the control lever 8, and on the support 7, a limiting arm 20 is installed with a longitudinal 21 and transverse 22-25 slots corresponding in the number of sliders 2 gearshifts,

In order to include the proposed mechanism of one of the gears, it is necessary to perform the following operations.

Claims (1)

for which the control lever 8 moves along the longitudinal groove 21 of the limiting link 20, while the end 19 moves along the groove 18 of the additional lever 16 (the two extreme positions in FIG. 3 are shown in dotted lines) and then inserted into one of the transverse grooves 22, 23 24 or 25, which, due to the effect of the end 19 of the lever 8 on one of the side surfaces of the groove 18 of the additional lever 16, translates, via its leader 17 and stops 6, the rod 5 with the driver 4 to select one of the sliders 2 gear changes. The movement of the end 19 along the groove 18 with the longitudinal movement of the control lever 8 changes the shoulder of its impact on the side surfaces of the groove 18 of the additional lever 16 relative to the axis 15, which ensures the same stroke in the transverse direction of the control lever 8 to select the near or far to the leash 4 of the slide rod 5 however, the application of force for selecting the sliders 2 is practically not required. The second operation consists in moving the selected slider 2 to activate a certain gear, for which the control lever 8, installed in one of the transverse grooves 22, 23, 24 or 25 of the limiting link 20, makes a swinging movement together with the support 7 relative to its axis, key 13 and groove 14, it is transmitted to the rod 5, through the driver 4, which moves one of the selected sliders 2 gear shifts. This requires effort to overcome transmission factors. Invention Formula The remote control mechanism of the vehicle's gearbox, containing the gear sliders installed with the possibility of linear movement relative to the body, is set to be connected with the possibility of a 5150 rotation and linear movement relative to the body. And the stem interacting with the slider holes by means of a driver with stops, the bearing pivotal with the stem and the control lever aligned with the stem, and the control lever with a handle at one end, mounted on the hinge middle part and connected to another end with rod stops, distinguished with. the fact that, in order to facilitate control when expanding the range of shifting gears, the rod and the support are fixed from the relative x- / 2 with the possibility of relative axial movement, and the mechanism is provided with an additional lever mounted on the hinge with a groove for engaging with the other end of the control lever and a driver for communicating with the rod stops, while the control lever is provided with a restricting arm connected to the support to ensure its longitudinal movements along the groove of the additional lever and lateral movements for engaging with the side surfaces of the groove of the additional lever. 6 in Fm.5
