Abstract

The invention relates to the transport engineering industry and can be used in manual gearboxes of automobiles with a manual drive for controlling the gearshift mechanism. The purpose of the invention is to facilitate the adjustment of the reverse gear shift. The device contains a control element for the reverse gear in the form of a lever 1, kinematically connected with the rod 4. On the lever there is a rod 13 equipped with a flat 16 and a threaded shank 15. A rod is fixed on the lever 1 with a nut 14 with the ability to change the position of the flat 16. The rod has a protrusion with a groove 18. The sides of this groove are parallel and may be located under a straight, acute or obtuse angle relative to the longitudinal axis of the rod. 4 il.

control of the box, its kinematic connection between the rod 4 and the reverse gear lever 1, which compensates for the errors in the performance of the parts and ensures that they move freely, without any changes. To adjust the position of the flats 16 of the leash 13, it is necessary to loosen the nut 14 and turn the screw 15 until a gap is formed between the edge 22 of the flats 16 and the ridge 21.

The device works in the following way.

When the forward gear is engaged, the control device shaft 8 moves up, the selector 7 rotates counterclockwise and, affecting the driver

axis 2 on body 3, and rod 4 with fixed 28. Due to the presence of a gap between the swivel plug 5 of the transmission on the front of the bored surface 21 and the roof 22 of the turn and the lead 6, the kinematic step 1 will remain stationary,

connected with a selector 7 with a crank 8 controls- 20 The position of the stem 4 and the coupling 25 with jiQifufi.transferred forward gear is shown in FIG. 1 thin dash-dotted line. Turning off this gear is carried out by returning all of these parts to their original neutral position. The shaft 8 is stirred down to engage the reverse.

Lever 1 has two protrusions 9 between which an insert 10 of antifriction material is placed and having two mutually perpendicular grooves — an annular for connecting the lever 1 and a rectangular one in which the controlled reverse gear 11 is placed. In the housing 3 there is a ball retainer 12, which interacts with the lever 1 and holding the protrusion 17 at the same time with its surface 19 in the neutral position. Lever 1 pitch 18 acts on the leash 13 and is also equipped with a leash 13, the lever 1 with respect to the axis 2 is made in the form of a rod fixed by means of an arrow. Simultaneously with the transfer lever 14. This pin has an adjusting position and gear 11 and will turn on the rear

The driver rod 13 will be covered with the protrusion 35 of the lateral sides 19 and 20 of the groove 17, made on the rod 4 for drying-18, which will prevent the spontaneous mixing of the lever 1 and gear 11. The reverse gear is shown in FIG. 1 dash line. Turning off the reverse is accomplished by returning the parts to their original neutral position — the rod 4, under the influence of the selector 7 and the shaft 8, moves to the left and the leash 13 slides along the side

kinematic connection between the rod 4 and the lever 1. The protrusion 17 is provided with a groove 18 having sides 19 and 20 of different lengths, while they are parallel to each other (Fig. 3). The smaller side 20 of the groove 18 is adjacent the free area 21, made parallel to the longitudinal axis of the rod 4. The sides 19 and 20 of the groove 18 are located relative to the longitudinal axis of the rod at an acute angle. The lead 13 with its edge 22 forms a gap with the platform 21.

The groove 18 of the protrusion 17 can be made with lateral sides 23 and 24 located at a right angle or obtuse angle to

The proposed transmission control device will simplify the design of the box and reduce the complexity of its manufacture. This is due to the location of the leash on the reverse gear lever, and the protrusion

The device works in the following way. When the forward gear is engaged, the control device shaft 8 moves up, the selector 7 rotates counterclockwise and, affecting the driver 5 6, mixes the stem 4 to the left. In doing so, the plug 5 will move to the left and insert the clutch. but in fig. 1 thin dash-dotted line. Turning off this gear is carried out by returning all of these parts to their original neutral position. The shaft 8 is stirred down to engage the reverse. The selector 7, turning clockwise, moves the stem 4 to the right and with it the plug 5 will move to the right coupling 25 on the hub 26 idle.  When this protrusion 17 surface 19 of the groove 18 acts on the leash 13 and turn 19, turn lever 1 with gear 11 to its previous position. The proposed transmission control device will simplify the design of the box and reduce the complexity of its manufacture. This is due to the location of the leash on the reverse gear lever, and the protrusion   groove - on the rod, as well as the ability to adjust the kinematic the connection between the rod and the lever without disassembling the box. Invention Formula 27 gears 28. After the final assembly of the gearbox, the device is adjusted using the vehicle's gearbox control unit, which contains a control element that is kinematically connected a rod having drivers for engaging forward and reverse gears, the reverse lead being rotatable on the body, while the axes of the stem and the reverse lead are mutually perpendicular and interconnected by means of a groove with the sides of different length, protruding from the lip, facing 12 to groove, characterized in that, in order to facilitate the adjustment of the reverse gear shift, the groove is made on the rod and the protrusion is placed on the reverse link and can be angled to adjust the relative position of the protrusion with the groove side of a smaller length. 28 27 25 26 1 sixteen Fi.
