Abstract

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

The technical result achieved by the claimed solution is to reduce the effort when selecting the gear included, increasing the reliability of the design of the gear selection lever.

This result is achieved by the fact that in the gearshift mechanism comprising a housing in which the gearshift shaft is mounted on the bearings, the gearshift lever fixed to the gearshift shaft is fixed, the gearshift lever contains a ball bearing for attaching the remote control gearshift cable and is fixed on the output end of the gearshift shaft, a support mounted on the wall of the housing, the gear selection lever is mounted in the support through a bolted connection and consists of a housing a flange mounted in a housing on bearing bearings, an upper arm and a lower arm with a spherical support, fixedly mounted at the ends of the housing, while the housing is rotatable around a fixed sleeve.

Description

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

Known remote gearshift gearbox, comprising a housing, a gearshift shaft, configured to rotate and linearly move, and mounted on bearings in the housing, a gear lever configured to move the gearbox rods with its sphere at the bottom stationary on the gearshift shaft, the gear lever, made with a groove in the upper part for the location of the slider, with the ability to rotate pressing together with a gearshift shaft, comprising a spherical support for attaching a remote control gearshift cable and fixed to an output end of a gearshift shaft, a gear selection lever made in the form of a curved plate, comprising a spherical support for mounting a gearshift cable and mounted on a housing wall through a support, a slider mounted on a ball bearing of the gear selection lever. [RF patent No. 142912 - prototype]

The disadvantage of this design is the increased force in the selection of the gear included, the low reliability of the design of the gear selection lever.

The technical result achieved by the claimed solution is to eliminate these shortcomings.

This result is achieved by the fact that in the gearshift mechanism comprising a housing in which the gearshift shaft is mounted on the bearings, the gearshift lever fixed to the gearshift shaft is fixed, the gearshift lever contains a ball bearing for attaching the remote control gearshift cable and is fixed at the output end of the gearshift shaft, a support mounted on the housing, the gear selection lever is mounted in the support through a bolted connection and consists of a housing, a sleeve, a mustache anovlennoy in the housing on the bearing supports of the upper arm and lower arm with a spherical bearing, fixedly attached at the ends of the housing, the housing rotatable around the fixed sleeve.

The inventive design solution is illustrated by drawings, where:

FIG. 6 - General view of the gear selection lever

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. At the output end of the gearshift shaft 3, the gearshift lever 5 is fixed, in the lower part of which there is a ball pin 6 for attaching the gearshift cable. On the support 7 of the housing 1 is fixed through a bolt connection 8 the gear selection lever 9, comprising an inner sleeve 10 mounted in the housing 11 on the bearings 12 for rotation, the upper lever 13 and the lower lever 14 with the ball bearing 15, fixed stationary at the ends of the housing 11 In this case, the housing 11 is made to rotate around a fixed sleeve 10 when securing the gear selection lever 9 in the support 7. The upper lever 13, enters the groove on the shift lever 5, with the possibility of its subsequent linear movement together with a shaft of the gear mechanism.

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 9 through the ball pin 15 on the lower lever 14 of the gear selection lever 9 and then through the upper lever 13 to the groove of the gear lever 5 (gear 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.
