Description

The invention relates to transport machinery, to the transmission of transport vehicles, to the NTS (ground transportation systems), including TTM (transport and technological vehicles), towing vehicles of road trains, SDM (construction and road vehicles), tractors, special purpose ground vehicles and etc.

Transmission aggregates are known - gearboxes (KP) with step change of gear ratios, containing gears, shafts, bearings, gear shifting devices used on domestic and foreign cars. (Osepchugov V.V., Frumkin A.K. Automobile: Structural Analysis, Design Elements. - M.: Mechanical Engineering, 1989. - 304 p.)

These units are structurally complex and metal-intensive.

Closest to the proposed manual gearbox (multi-stage gearbox) is the gearbox (gearbox) according to patent RU No. 2349816 C1. (Bull. No. 8 of 05.20.2009). Authors Nekrasov V.I. and Shiyka A.P.

MCP type 16R4 according to patent RU No. 2349816 C1 consists of a coaxial three-shaft gearbox. Seven pairs of gears engaged with each other, a series of reverse gears with an intermediate gear on a separate axis, four three-position shift clutches and one two-position gear provide 16 forward gears and 4 reverse gears.

The disadvantages of the described transmission unit are the limitation of the operational and layout characteristics of the vehicle due to an insufficient number of gears and a range of gear ratios, high gear ratios of the extreme gears, which leads to an increase in the axle distance and transverse dimensions; reduce the accuracy of gears due to the bending of the shafts with their considerable length, this causes noise, reduced efficiency and durability of the MCP.

The problem to which the invention is directed, is to expand the operational and layout capabilities of the vehicle.

The problem is solved by the modular layout of the MCP.

The achievement of the technical result is ensured by the fact that the multi-stage gearbox consists of a crankcase with an inner wall, input and output shafts are coaxially mounted in their bearings, an intermediate shaft is located parallel to them, seven pairs of interlocked forward gears, driving and driven reverse gears are installed on these shafts , between them on a separate axis there is an intermediate reverse gear, while the inner wall is installed in the middle of the crankcase, coaxially installed between the input and output shafts two additional shafts are introduced, on each of them two gears and a hub with a two-position switching clutch are fixed, the first additional shaft is located in the first additional support and in the front end of the second additional shaft, which is installed in the second additional support and in the support of the middle crankcase wall, the front end of the first additional shaft is supported by an input shaft on which the gear is freely mounted and the hub is fixed with a three-position switching clutch located on it, at the rear At the end of the second additional shaft, an output shaft with a hub fixed to it and a three-position switching clutch is mounted, a gear block with a tubular shaft and a separate gear are freely mounted on this shaft, two gear units with tubular shafts are freely mounted on the intermediate shaft at the edges, four in the middle part separate gears, one of them is a driven reverse gear, three hubs are fixed with three-position switching clutches installed on them: the left clutch opposite the first additional shaft between th unit gears and a gear clutch opposite the average of the second additional shaft between the individual gears, the right clutch shaft opposite the output gear unit between the right block and a pinion gear; gears of blocks and separate gears are equipped with gear rims for switching clutches.

In fact, the MCP consists of two-shaft misaligned gearboxes: six-speed type 6R2 according to patent No. 2149767 (Bull. No. 15 dated 05/27/2000. Author Nekrasov V.I.) and four-speed type 4R2 based on copyright certificate No. 1654038 A1 (Bull. No. 21 dated 07.06 .1991 by V. Nekrasov) with a common intermediate shaft.

In FIG. Figure 1 shows the kinematic diagram of a manual gearbox (multi-stage gearbox) of type 36R16 (36 forward gears and 16 reverse gears), consisting of two non-coaxial twin-shaft gearboxes (gearboxes) with a common intermediate shaft (bottom). Shift clutches are shown in neutral (H) position. In the lower part in circles, numbers (1-7) of gear pairs are shown, as well as the designation (R) of a series of reverse gears for the table of the radiation diagram of FIG. 2.

In FIG. 2 shows a beam diagram of the gear ratios provided by the manual gearbox shown in FIG. 1. Between the horizontal lines are rays characterizing the structure and operation of the gearbox. On the middle horizontal, gear ratios are shown on a uniform logarithmic scale (lq U); the beam characterizing the gear ratio does not change its appearance throughout the diagram. Point 0 is marked on the lower horizontal, which corresponds to the entrance to the MCP; five rays emerge from this point. A beam directed to the right indicates a deceleration, the more the beam, the higher the gear ratio. For example, a gentle beam 1 to the point lq U ₁ = 0.61; provides a gear ratio U ₁ = 4.07; ray R to the point lq U _R = 0.42; provides a gear ratio U _R = 2.63; beam 4, equal to lq U ₄ = 0.3; provides a gear ratio U ₄ = 1,995; steep beam 3, equal to lq U ₃ = 0.01; provides a gear ratio U ₃ = 1,023. A beam directed to the left indicates an accelerating transmission, the better the beam, the lower the gear ratio. For example, ray 2 to the left, equal to lq U ₂ = -0.29; provides a gear ratio U ₂ = 0.513; beam 2 to the right, equal to lq U ₂ = 0.29; provides a gear ratio of U ₂ = 1.95. Between the upper horizontals: beam 5, equal to lq U ₅ = 0.04; provides a gear ratio U ₅ = 1,096; beam 6, equal to lq U ₆ = 0.06; provides a gear ratio of U ₆ = 1,148; beam 7, equal to lq U ₇ = 0.09; provides a gear ratio U ₇ = 1.23. Forward gears 1-36 are shown above the upper horizontal, reverse gears 1R - 16R are shown below the lower horizontal. Rays 2, 3 and R are represented twice: beam 2: a) from t. 0 up to the left and b) from the end of beam 1 to the right down; beam 3 to the right upward: a) from t. 0, b) from the end of beam 2; R ray up to the right: a) from t. 0, b) from the end of beam 2. Beam 4 is presented 4 times: a) from t. 0 up to the left, b) from the end of beam 2 to the right up; c) from the end of beam 3 to the left down; d) from the end of beam 2 to the left down. Above the gear designations (1-36) is a table of the positions of the shift clutches: L - left, H - neutral and P - right. At the top of the table, torque transformation paths are shown. For example, in 1st gear (right edge of the table), the torque is transformed by six pairs of gears: 1-2-4-5-6-7. Two dashes indicate the transmission of torque from the second additional shaft to the output shaft via clutch E. For example, in the 6th gear, the designation 1-2-6-7 indicates that the 1st and 2nd pairs of gears are working in the left gearbox, then, through couplings C and E, the torque is supplied to the gear block of the right gearbox and then it is transformed by the 6th and 7th pairs of gears.

MCP consists of a crankcase 1 with an average inner wall 2 (Fig. 1). In the supports of the crankcase 1 and the middle wall 2 are coaxially arranged shafts: input 3, first and second additional 4 and 5, output 6. Parallel to it, an intermediate shaft 7 is installed. A block of two gears 8 and 9 is mounted on the first additional shaft 4, a block of two gears 10 and 11 are mounted on the second additional shaft 5. The first additional shaft 4 is installed in the first additional support 12 and in the end face of the second additional shaft 5, which is installed in the support of the middle wall 2 and in the second additional support 13.

At the rear end of the first additional shaft 4, a hub is fixed with a two-position switching clutch 16 (C) mounted on it. At the front end of the first additional shaft 4, there is a support of the input shaft 3, on which a hub with a three-position switching clutch 17 (A) is fixed and a separate gear 18 is freely mounted. The left block of two gears 19 and 20 mounted on the left tubular shaft 21 is freely mounted on the intermediate shaft 7, on which the hub with the left three-position clutch 22 (B) is fixed.

Gear block 32 and 33, mounted on the shaft 34, differs from gears 8 and 9 of the additional shaft 4 of the left side of the MCP in that the shaft 34 is tubular and freely mounted on the output shaft 6. Gear 32 is engaged with gear 27 and gear 33 with gear 29. Hub with three-position clutch 15 (G) reflection of the hub with the coupling 17 (A). A separate gear 35, freely mounted on the output shaft 6, is engaged with the gear 30, the reflection of the gear 18 of the input shaft 3. The intermediate gear 36 is located on a separate axis 37, parallel to the other shafts in the supports of the middle wall 2 and in the additional support 38. Gears 8, 10, 18, 20, 23, 24, 25, 27, 29, 32, 33 and 35 are equipped with gear rims.

The work of the MCP is as follows.
