USEFUL MODEL

Utility model. The gearshift knob belongs to the automotive industry and can be used in automobiles for mechanical, remote gearshift and pneumatic control of the gearshift divider or gearbox.

BACKGROUND

Known shift gear knob, combined with a switch valve control pneumatic gear shifter gear divider used in trucks of the KAMAZ family; KAMA3-5320f KAMAZ5410, KAMAZ-53212 (see the Catalog of parts and assembly units of KAMAZ automobiles Novosibirsk, 1996, p. 330, fig. 101, pos. 8, 13.15.)

The closest to the utility model in terms of features is the gear knob of the KAMAZ-5320 car (see KAMAZ-5320, KAMA3.4310, URAL. 4320 Moscow 1987 cipJ52, Fig. 4L1, item 1,2, }, which is a cylindrical tip of the gear shift lever combined with the housing including the pneumatic gear drive of the divider.

The disadvantages of the closest analogue include the following;

- the pneumatic drive switch is a mechanical lever switch, the forces with which are transmitted through the braided cable to the spool of the control valve of the pneumatic drive of the divider located on the gearbox of the car engine. Due to friction between the cable and the braid, a large switching force is created on the switch, which leads to a cable breakage and breaker switch;

- at sub-zero operating temperatures, the cable located outside the driver’s cab freezes to the braid and it is very difficult to turn on the transmission;

-the need to use grease in a pair of wire-braid, requires additional economic and technical measures and has a negative impact on the environment.

ESSENCE OF A USEFUL MODEL

The objective of the claimed utility model is to eliminate these drawbacks by creating a design for the gear lever with a pneumatic gearshift valve divider that meets modern requirements for ergonomics, effort, shifting and reliability.

The proposed shift knob, the layout elements of which are shown in the drawing, consists of a cylindrical housing 1, fixedly mounted on the lever 2 using a spring washer 3 and nut 4,

A two-position pneumatic valve with elements 5 ,,. 8 is placed in the housing. From above, the housing will be covered with a fastener 9, on the outer surface of which the company logo or gearbox shift scheme is applied.

Bottom to the body, through fittings 10 and couplings 14 are connected plastic air ducts 1, one inlet and two outlet. Depending on the position of the flag 8 of the pneumatic valve in each of its fixed positions; air is supplied through one of the exhaust ducts.

Plastic ducts in installation are more convenient than metal ones, have fewer joints and, therefore, less chance of air leakage,

The design of the handle provides for its fixation against rotation around its axis by elements 12.13, which protects against twisting and flogging of air ducts.

The new handle consists of fewer parts and has one sealing element 15, but retains all the connecting dimensions from the standard on the KAIvIASe, therefore it is easily installed instead of it without any modification and has the ability to control the gear divider or demultiplier, as with a two-wire one (box KAMAZ or YaMZ transmissions), or a single-wire (imported gearbox) air connection to the air distributor, while using a single-wire air connection, imo plug one of the outlet ducts of the handle.

Thanks to the modern design and the materials used, the shift knob has a modern design, pyiai-friendly shape, non-slip, rough outer surface. The check valve of the pneumocrane is easy to move and clearly fixed, there is no effect of adhesion of surfaces

rubber products to metal, which helps to increase the resource of the handle and ease of use.

Using the proposed design of the handle allows you to exclude traction cable-braid, valve control valve pneumatic drive, simplify the layout of the air distribution and reduce its loss, significantly reduce the effort to engage the gear divider and improve the working conditions of the driver,
