Description

The invention relates to transport machinery, to the transmission of transport vehicles, to the NTS (ground transportation systems), including tractor vehicles of road trains, SDM (construction and road vehicles), tractors, special purpose ground vehicles, 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, Elements of Calculation. - M.: Mechanical Engineering, 1989. - 304 p.).

These units are structurally complex and metal-intensive.

Closest to the proposed 24-speed manual gearbox (multi-stage gearbox) is the gearbox according to patent RU No. 2050290 C1 (Bull. No. 35 from 12.20.1995).

The shaft-planetary gearbox 16R8 according to RU patent No. 2050290 consists of an uncoaxial two-shaft 8-speed unit and a simple three-link PM (planetary gear) operating in three modes: direct gear, slow gear and reverse gear. 8 gears, three shifting clutches (one of them double) of the unit and three PM links (sun gear, epicyclic wheel and carrier with satellites) with two shifting clutches provide 16 forward gears and 8 reverse gears.

The disadvantages of the described transmission unit are the limitation of the operational characteristics of the vehicle with an insufficient number of gears and a gearbox range (ratio of gear ratios of lower and higher gears).

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

The problem is solved by increasing the number of gears and the range of the manual gearbox.

The achievement of the technical result is ensured by the fact that the misaligned shaft-planetary gearbox contains a two-shaft unit with four pairs of interlocked gears and a simple three-link planetary mechanism, on the input and secondary shafts freely mounted on a block of two gears and two separate gears, on each shaft between separate the gears with a three-position switching clutch are fixed by gears, and oppositely deployed two-way gears are located between the blocks and a separate gear on the gear crowns ozionic coupling halves interconnected by a switching fork, the planetary gear sun gear is fixed to a shaft on which a gear ring is also mounted, an output shaft with a three-position gear ring, on which a three-position switching clutch is mounted, is aligned with the sun gear shaft; the satellites located on the axles of the carrier are engaged with the sun gear, as well as with the epicyclic wheel, to the body of which a tubular output shaft with a gear rim is fixed, next to it is a gear rim of the tubular output shaft of the carrier, a two-position clutch is mounted on the gear rim of the housing wall next to a gear rim of the tubular input shaft of the epicyclic wheel body and a gear rim of the tubular input shaft of the planetary gear carrier, while a two-position gear is fixed to the output of the secondary shaft a crown with a two-position switching clutch, next to this ring gear there is a ring gear of the entrance of the sun gear mounted on the shaft of this gear.

In FIG. Figure 1 shows the kinematic diagram of an off-axis shaft-shaft manual gearbox (multi-stage gearbox), type 24R8 - 24 forward gears and 8 reverse gears, consisting of an off-axis two-shaft 8-speed unit and a simple three-link PM (planetary gear). In the lower part in circles the numbers of gear pairs for the table of the radiation diagram are shown (Fig. 2). Clutches A, B, C, and D in the neutral position, clutches Ε and F in the upper part are shown when the PM is operating in forward gears U ^b _ah = K + 1, in the lower part - in reverse gear U ^h _ab = - | K |. Under the ring gears, their positions in the table of FIG. 2: 22 and 37 - I; 28 and 30 - II; 33 and 23 - III.

In FIG. 2 shows a beam diagram of the gear ratios provided by the manual gearbox shown in FIG. 1. In the upper part of the middle horizontal, the gear ratios (U) are given in an uneven scale, in the lower part - in the uniform logarithmic scale (lq U), while the beam characterizing the gear ratio does not change its value. Point 0 on the lower horizontal indicates the input of torque into the MCP; four beams 3, 2, 1 and 4 come out from this point, corresponding to the gear ratios of the pairs of gears: U ₃ = 1.58; lq 1.58 = 0.2; U ₂ = 2.19; lq 2.19 = 0.34; U ₁ = 2.57; lq 2.57 = 0.34; U ₄ = 3.1; lq 3.1 = 0.49.

From the middle horizontal, three groups of rays are directed toward the upper horizontal and one group toward the lower horizontal. These rays characterize the magnitude of the gear ratios PM (planetary mechanism) with an internal parameter K = 2.63. K = Z _b / Z _a is the internal parameter PM equal to the ratio of the number of teeth of the epicyclic wheel to the number of teeth of the sun gear. Eight gentle rays directed upward to points 24-17 indicate an accelerating mode of operation, the gear ratio is less than one, U ^b _ha = 1 / (K + 1) = 1 / 3.63 = 0.275; lq 0.275 = -0.56. Eight vertical rays directed upward to points 16–9 indicate direct transmission, the gear ratio is one, U _(hh) = 1.0; lq 1.0 = 0.0. Eight gentle rays directed upward to points 8-1 indicate a decelerating mode of operation, the gear ratio is greater than one, U ^b _ah = K + 1 = 3.63; lq 3.63 = 0.56. Eight gentle rays directed to the right down to points 8R-1R indicate reverse gears in slow mode, gear ratio is greater than one, U ^h _ab = - | K | = 2.63; lq 2.63 = - | 0.42 |. A minus sign indicates a change in the direction of rotation of the output shaft compared to the input shaft.

Where: U is the gear ratio, the index at the top indicates the stopped link PM, for example, for 1st gear U ^b _ah : “b” is the epicyclic wheel, the indices at the bottom “ah” are the links of the input (sun gear) and output (carrier) power flow.

At the output of the shaft unit we get eight modes of operation with different gear ratios: the 1st mode is provided by three pairs of gears: 1-3-4, and the third pair of gears works in an accelerating mode - from a large gear to a smaller gear, U _p1 = U _1x (1 / U ₃ ) × U ₄ = 2.57 × 1 / 1.58 × 3.1 = 5.04; lq 5.04 = 0.7; after PM we get the 1st, 9th, 17th forward gears and 1R - 1st reverse gear; The 2nd mode is also provided by three pairs of gears: 2-3-4, u _p2 = U _2x (1 / U ₃ ) × U ₄ = 2.19 × 1 / 1.58 × 3.1 = 4.3; lq 4.3 = 0.63; after PM we get the 2nd, 10th, 18th forward gears and 2R; The 3rd mode is also provided by three pairs of gears: 1-2-4, U _p3 = U ₁ × (1 / U ₂ ) × U ₄ = 2.57 × 1 / 2.19 × 3.1 = 3.64; lq 3.64 = 0.56; after PM we get the 3rd, 11th, 19th forward gears and 3R; The 4th mode is provided by the 4th pair of gears: U _p4 = U ₄ = 3,1; lq 3.1 = 0.49. after PM we get the 4th, 12th, 20th gears of the forward gear and 4R; The 5th mode is provided by the 1st pair of gears: U _p5 = U ₁ = 2.57; lq 2.57 = 0.41. after the PM we get the 5th, 13th, 21st forward gears and 5R; The 6th mode is provided by the 2nd pair of gears: U _p6 = U ₂ = 2.19; lq 2.19 = 0.34. after the PM we get the 6th, 14th, 22nd forward gears and 6R; The 7th mode is also provided by three pairs of gears: 1-2-3, U _p7 = U ₁ × (1 / U ₂ ) × U ₃ = 2.57 × 1 / 2.19 × 1.58 = 1.854; lq 1.854 = 0.27; after the PM we get the 7th, 15th, 23rd forward gears and 7R; The 8th mode is provided by the 3rd pair of gears: U _p8 = U ₃ = 1,58; lq 1.5819 = 0.2; after the PM we get the 8th, 16th, 24th forward gears and 8R.

Separate gears 6, 7 and gear block 8-9 are freely mounted on the input shaft 2 and, on the secondary shaft 3, a block of gears 10-11 freely engaged with gears 6 and 7 of the input shaft 2, as well as separate gears 12 and 13, engaged with gears 8 and 9 of the input shaft block 2, are freely mounted. On the gear ring mounted on input shaft 2 between the individual gears 6 and 7, is installed three-position I clutch 14 (A) of the input shaft 2. On the gears of the individual gears 7 and 12 of the input 2 and secondary 3 shafts are located the opposite-deployed on-off shift half-couplings 15 and 16 (B) interconnected by the shift fork 17.

The sun gear 21 (a), the gear rim 22 of the inlet of the sun gear 21 and the gear rim 23 of the output of the sun gear 21 on the shaft 4 are fixed on the shaft 4. In the carrier 24 (h) of the PM, satellites 25 are mounted engaged with the sun gear 21 and the epicyclic wheel 26 (at). Drove 24 with a tubular input shaft 27 is connected to the ring gear 28, and a tubular output shaft 29 is connected to the ring gear 30.
