Abstract

This invention relates to electrical engineering, in particular to car direction indicator switches. The purpose of the invention is to reduce the labor intensity of manufacturing and material consumption. When the lever 2 is rotated, the contacts of the turn indicator are closed and sector 6 is rotated. In this case, the elastic-flexible axis 7 moves along the profile surface at the bottom of the grooves made in the projections 18 and 19 of sector 6. The cracker 8 located on the axis moves towards the release ring 5. When turning off the washer, its cams engage on the end of the cracker 8. Turning the cracker 8, the cams of the washer 5 act on sector 6, returning it and the lever 2 to its original state. 1 hp ff, 10 il iB i 7.24 19 iO 5 f5 ii (L 00 tc 00 00 SP 00 ZliQ 2

Description

This invention relates to electrical engineering, in particular to car direction indicator switches.

The purpose of the invention is to reduce the labor intensity of manufacturing and material consumption.

Figure 1 shows the direction indicator switch, a longitudinal section; figure 2 - section aa in figure 1; on fig.Z - section bb in figure 1; figure 4 - the same, in the switched position. nii; on fig.Z - section bb In figure 2 on figure 6 - section G-D in figure 1; figure 7 is a view of D in figure 1; on Fig - section EE in figure 2; figure 9 is a section of the LC in figure 2; figure 10 - sector, top view. "

The turn signal switch contains hollow body 1, control levers 2 and 3 mounted on axis 4, fixed in hollow body 1 and provided with sliding contacts (not shown), switch off washer 5, sector 6, elastic bend 7 and spring-loaded biscuit 8.

The hollow body 1 includes protrusions 9 and 10, the grooves 11 and 12 of which serve as guides for moving the elastic-flexible axis 7, as well as a stiffening rib with a partition 13, which is a fixing element and is reciprocating, and with the end of the elastic-flexible axis 7

The shift lever 2 of the direction indicators is provided with a protrusion 4 which engages with the groove 15 of the sector 6.

Sector 6 is equipped with stops 16 and 17 and protrusions 18 and 19, Stops 16 and 17 act on the projections 20 and 21 of the cracker 8. The projections 18 and 19 are equipped with identical grooves 22 and 23 with grooves at the bottom of the grooves. The groove 23 of the protrusion 19 is bounded by a wall 24.

The inclusion washer 5, movably connected with the hollow body 1, is connected with the steering wheel (not shown) and has two cams 25 and 26 acting on the cracker 8.

The elastic bending axis 7 is filled out of the n} dinner, wound without a gap between the turns, passes through the opening 8 and is placed in the grooves P and. 12 of the housing 1 and in the slots 22 and 23 of the sector 6. It is prevented from axial movement by the wall 24 and the partition 13,. The switch works as follows.

 In the neutral position of the lever 2, the elastic-flexible axis 7 is located in the groove at the bottom of the grooves 22 and 23 of sector 6, in the lower part of the grooves 11 and 12 of the housing 1. At the same time, the cracker 8 mounted on the elastic-flexible axis 7 occupies the lower position, which ensures a guaranteed clearance Z between the cracker 8 and the cams 25 and 26 of the shutdown washer 5;

The sector 6 driven by the protrusion 14 of the lever 2 rotates counterclockwise. Since the movement of the elastic-flexible axis 7 in the horizontal direction is limited by the projections 9 and 10 of the housing 1, under the action of the switching force (when the sector is rotated) it begins to move up the walls of the grooves to the flat part of the bottom of the grooves 22 and 23 of the projections 18 and 19 of sector 6 and takes top position.

A cracker 8 mounted on an elastic-flexible axis 7 rises, choosing a guaranteed gap Z, and takes a position on the trajectory of movement of the cams 25 and 26 of the shutdown washer 5.

If the right turn is not finished ,. The off-side washer 5, driven by the steering wheel, continues to rotate clockwise. The cams 25 and 26 of the iaiba 5 of the disengagement alternately engage with the rusk 8 and rotate it relative to the elastic bending axis 7 counterclockwise, but the protrusion 21 of the rusk 8 does not reach the stop 17 of the sector 6. The cams 25 and 26 of the off switch 5 skip and lever 2 remains in the right turn position.

If the right turn is completed, the steering wheel, and with it the washer

5 off, turn counterclockwise. Cam 26 washers 5 off ,, the hook rusk 8, rotates it clockwise around the elastic axis 7, the protrusion 20 cracker 8 pushes the stop 16 sector

6-and turns it clockwise, and sector 6 returns lever 2 to the neutral position. At the same time, the spring-loaded cracker 8 returns the elastic-flexible axis 7 to the initial state.

When you turn on the left turn indicator switch works in a similar way.

When the lever 2 is in the on position, i.e. rusk 8 with an elastic bending axis 7 occupies the upper position, the cam 26 of the shutdown washer 5 acts on the crush 8. Elastically, the axle 7 bends, the cracker 8 descends and the cam 26 slips, ensuring further turn of the shutdown washer 5.

The lever 2 is fixed in three positions (in neutral, left and right) by means of the ball 27, which is pressed by the spring 28 to the figured grooves of the fixation mechanism.
