Abstract

A gearshift mechanism comprising a housing, a gearshift lever, characterized in that the gearshift mechanism is configured to remotely shift gears and includes a gearshift shaft configured to perform a rotational movement and linear movements, and a lever mounted in the housing on bearings gear shift, made with the ability to move the gearbox rods with its sphere at the bottom, fixed to the gearshift shaft fixedly, the lever is on gears, made with a groove in the upper part for the location of the slider, with the possibility of rotational movement together with the gearshift shaft, containing a ball bearing for attaching the cable for switching the gears of the remote drive and mounted on the output end of the gearshift shaft, gear selection lever, made in the form a curved plate containing a ball bearing for attaching the gear selection cable and mounted on the housing wall through the support, a slider mounted on the ball bearing of the gear selection lever.

Description

The utility model relates to the field of engineering, in particular, to the transmission control system of a vehicle.

Known gearshift mechanism of the gearbox of the car "GAZelle", comprising a gear housing mounted on the gearbox, a gear lever mounted in the gear housing [1].

The disadvantage of this design is the location of the gearshift lever directly in the housing of the gearshift mechanism, mounted on the gearbox, the design does not provide remote gearshift control.

The technical result achieved by the claimed solution lies in the possibility of shifting the gearbox of the gearbox remotely and the location of the gearshift lever on the instrument panel or in another place in the cab.

This result is achieved by the fact that the gearshift mechanism is configured to remotely shift gears and includes a gearshift shaft configured to make a rotation movement and linear movements, and mounted on bearings in the housing, a gearshift lever adapted to move with its sphere at the bottom of the transmission rods, fixed to the gearshift shaft motionlessly, the gear lever, made with a groove in the upper part for positioning a slide, with the ability to rotate together with the gearshift shaft, comprising a spherical support for attaching a remote control gear shift cable and fixed to an output end of a gearshift shaft, a gear selection lever made in the form of a curved plate containing a spherical support for attaching a gear cable gears and mounted on the wall of the housing through the support, a slider mounted on the ball bearing of the gear selection lever.

The inventive design solution is illustrated by drawings, where:

FIG. 1 - General view of the claimed design of the mechanism

FIG. 2 - General view of the current design of the gearshift mechanism - prototype

The claimed mechanism comprises a housing 1, in which a gearshift shaft 3 is mounted on the bearings 2. A gearshift lever 4 is mounted on the gearshift shaft 3, which is rigidly fixed from movement relative to the gearshift shaft 3. At the output end of the gearshift shaft 3, the gear lever 5 is fixed , in the lower part of which there is a ball pin 9 for fastening the gear shift cable. On the wall of the case of the mechanism through the support 6, a gear selection lever 7 is installed, in which a ball bearing 10 for mounting the gear selection cable and a ball bearing are mounted 11. A slide 8 is mounted on the ball bearing 11, which, when mounted, enters from the groove on the gear lever 5, made in its upper part. The gearshift assembly is mounted on the gearbox and secured with a bolted connection.

The gearshift mechanism operates as follows. When the selected gear is engaged, the driver, acting on the gear lever, creates tension on the drive cables, which on the other hand are connected to the ball joints on the levers of the gear mechanism, as a result of which the force is transmitted from the driver's hand to the gear mechanism levers. When gear selection - the impact is carried out by the gear selection lever 7 through the slider 8 on the groove of the gear lever 5 (shift shaft 3 moves linearly). Further, acting through the cable on the gear selector 5 and turning it together with the gearshift shaft 3 and gearshift lever 4, the gear selected by the driver in the gearbox is engaged.
