Description

The invention relates to the field of mechanical engineering, to devices for remote control of mechanisms, in particular, for gear shifting in a gearbox of vehicles.

Known gearshift lever [1], containing a removable upper part with a handle and a lower part for acting on the gearshift mechanism. The device comprises a docking unit with a detachable connection for holding the upper and lower parts. The docking unit has a protrusion on the lower end surface of the upper part of the lever and a recess mating with the protrusion located along the longitudinal axis of the lower part of the lever. The joined protrusion and the recess are held in the attached state by the latch.

This device is installed directly on the gearshift mechanism, the design does not provide remote gearshift control.

There is also a known mechanism for shifting and controlling a remote gearshift drive [2], comprising a base fixed in the cab and pivotally connected to the base of the handle, on the lower end of which is mounted an element of the remote drive. The handle is mounted at the base on a spherical joint. The lower end of the handle rod is pivotally connected by a fork fixed to the end of the distance rod. Remote gear shifting is provided by a set of several articulated remote booms. Thanks to the spherical hinge, the handle can deviate from the initial central position (corresponding to the neutral in the gearbox) in vertical planes by the required angle in any direction corresponding to a full circle of 360 °. When the handle is deflected to the left or right, the remote rods rotate around its axis, providing a choice of gears. The deviation of the handle back and forth moves the distance rods reciprocating and ensures the inclusion of gears.

The kinematics of the mechanism provides reliable gear shifting when using remote booms to control a remote gearbox. However, if a cable drive is used to remotely transfer control movements to the gearbox, this gearshift mechanism and control the remote gearshift drive cannot be applied due to differences in the kinematics of the drives.

The upper part of the handle must in any case make the same movements familiar to the driver. At the same time, the lower end of the handle must be connected to special structural elements that provide kinematics corresponding to a specific remote drive - cable or made from a set of distance rods.

Since the use of cables for a remote gearshift drive is a relatively new direction in the development of drives compared to drives based on remote rods, the search for solutions aimed at creating effective designs of control devices for cable drives is relevant today.

The objective of the claimed utility model is to adapt the known gearshift control devices for new conditions - for cable remote drives - while maintaining the traditional gearshift scheme by the driver's handle.

The technical result consists in reducing the cost of the remote drive and ensuring reliability in operation.

Obtaining a technical result from solving the problem is due to the fact that the proposed new control mechanism allows the use of a simpler drive design (the number of parts is significantly reduced), which results in operational reliability, as much fewer connection points remain.

The technical result is achieved by a device for controlling a remote gear shift mechanism. The device comprises a base fixed in the cab and a handle pivotally connected to the base, at the lower end of which a remote drive element is fixed.

New is that the base is made in the form of a housing with vertical walls. In the case on two horizontal spikes installed

a crosspiece, on two other spikes of which are located vertically, a link is mounted. In the upper part of the backstage there is a nest for the handle, and on the sides there are elements for connecting the cables in the form of two tides with connecting holes made on the bottom end of the backstage. The axis of the horizontal spikes of the cross passes through the middle of the wings, and the axis of the socket with the handle is parallel to the axis of the vertical spikes. Both axes are located in a vertical plane of symmetry and are spaced apart by a specified eccentricity. The axis of the horizontal spikes is perpendicular to the direction of travel of the vehicle. The eccentricity between the axis of the socket with the handle and the axis of the vertical spikes of the cross is 35 ÷ 40 mm. The tides on the wings are symmetrical with respect to its vertical plane of symmetry. Cross spikes are installed in the housing and in the wings on the bearings. The socket for the handle is made with a slot and provided with a coupling bolt. A corrugated dust cover is installed on the case. Bearing bearings are made in the form of plastic bushings.

The drawings show the inventive device.

In Fig.1 a device for controlling a remote cable drive; figure 2 - installation of the device on a remote cable drive; figure 3 is a longitudinal section of the device.

The device consists of a housing 1, in the openings of which a crosspiece 3 is installed on two horizontal spikes 2. A drawstring 5 is mounted on two other spikes 4 of the crosspiece vertically. A handle 6 is fixed to the top of the drawer hole, fixed by a coupling bolt 7. On the two sides of the drawer two tides 8 with holes for articulated connection of the cables 9 are symmetrically made at its lower end. Supporting brackets 10 are installed in the area where the cables are connected to the actuators. On the opposite side, the cables are connected s lug 11 provided on the casing-plug translator. A foot 12 is also made on the plug housing, connected to the jet link 13. The translator housing 14 is pivotally connected to the plug housing, mounted on the shaft of the gear shifting mechanism 15.

The device operates as follows.

Making the choice of gear, the driver rejects the wings 5 with the handle 6 to the left or right at a certain angle. At the same time, the crank with the wings rotates around

vertical axis (axis of the vertical spikes of the spider 3). This rotation is due to the presence of a lever with a shoulder between the rotation point (the axis of the vertical spikes 4) and the point of application of force on the lever 6. The cables 9, pivotally connected to the tides 8, are displaced in opposite directions relative to each other. In this case, the cables create a moment on the translator in the horizontal plane, which, thanks to the jet thrust 13 connected to the tab 12, is converted into axial force by the gearshift rod. The rod moves in the axial direction, the gear is selected.

Carrying out gear shifting, the driver deflects the link 5 with the handle 6 forward or backward at a certain angle. In this case, the handle with the wings are rotated around the horizontal axis (axis of the horizontal spikes of the cross 3).

The cables 9 are moved in one direction by a certain amount (20 ÷ 25 mm). Under the influence of the cables, the translator mounted on the gearshift shaft rotates around the shaft axis and, accordingly, rotates the shaft itself, as a result of which the fork fixed on the shaft engages the corresponding gear.
