Description

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

These units are structurally complex and metal-intensive.

The gearbox through the clutch interacts with the internal combustion engine (internal combustion engine), to start which electric starters are used. MCPs (multi-stage gearboxes) are used on heavy vehicles with high-torque ICEs, which require electric starters and high-capacity batteries to start, which must provide a powerful starting current.

To start the internal combustion engine with an electric motor and a low-power battery, electric inertia starters are used, which spin the flywheel to a high speed through the drive. The energy accumulated by the flywheel through the gearbox, reducing the speed, is sent to the ICE crankshaft to start the engine.

The electric inertia starter according to the copyright certificate No. 1357258 A1 (bull. No. 45 dated 12/07/1987. Authors Nekrasov V.I. flywheel. This starter has a complex design of three friction clutches and insufficient opportunities to increase the flywheel’s rotation speed due to the small gear ratio between the electric motor and the internal combustion engine, limited by three rows of gearbox gears.

Closest to the proposed manual gearbox (multi-stage gearbox), compatible with the electric inertia starter, is the gearbox according to patent RU No. 2050290 C1 (bull. No. 35 from 12.20.1995. Author Nekrasov V.I.).

The first stage - flywheel promotion

Clutches 24 (B) and 10 (G) in neutral (N) position, primary 6 and output 8 shafts are disconnected. The ICE crankshaft 3 with the coupling 5 (A) is disconnected from the flywheel 61, 62 (top view of the clutch) and connected to the ring gear 60 at the front end of the turned off primary shaft 6. The clutch with the bearing 70, the internal elements of the exhaust diaphragm spring 66 is in the extreme right position. The clutch pressure plate 65 by couplers 71, the exhaust ring 72 of the clutch release clutch 69 is moved away from the master 61 and the follower 59 of the clutch plate to the maximum distance, while the internal gear ring 73 of the pressure disk 65 is closed with the outer gear ring 76 of the tubular shaft 75 of the gear wheel 11 of the first row ( from). The epicyclic wheel 52 (b) PM is stopped relative to the housing 1 by a sleeve 77 (F), which closes the gears 78 and 55.

From the drive shaft 37 of the motor 36 through the ring gear 38 and the coupling 39 (E), the torque is supplied to the wide ring gear 41 (top view), the fifth row (i) of gears 42-43, the force is transmitted to the carrier 46 through the tubular input shaft 45 ( h) and axles 49 of satellites 50. Satellites 50, rolling around a stopped epicyclic wheel 52 (b), rotate the sun gear 51 (a) and the secondary shaft 7 with a significantly increased speed. From the ring gear 26 by the coupling 25 (D), the force is transmitted to the fourth row (1) of gears 19-14, along the tubular shaft 15 to the third row (e) of gears 13-18, along the lower sleeve 30 (C) from the ring gear 33 to a wide ring gear 35, along the tubular shaft 20 to the first row (s) of gears 16-11, the tubular shaft 75, along the ring gears 73-76 onto the pressure plate 65, a robust massive flywheel ring 62 and a clutch drive plate 61. Massive clutch drive elements 61 , 62 and 65 rotate with high frequency and accumulate kinetic energy, which in the future must be transferred to the crankshaft 3 with a low speed.

The gear ratio between the motor shaft and the flywheel will be

The frequency of rotation of the flywheel in comparison with the frequency of rotation of the drive shaft of the electric motor will increase by almost 30 times.

The second stage - starting the internal combustion engine

To start the internal combustion engine, the kinetic energy of the flywheel accumulated at a high speed of rotation must be transferred to the crankshaft with a reduced speed.

We disconnect the drive shaft 37 of the electric motor 36 from the wide gear ring 41 of the gear 42 by moving the coupling 39 (E) from the right (P) position to the neutral (H) position. We turn on the disk friction synchronizer, clamping the driven 80 and drive discs 79 (the booster is not shown), when aligning the speed of the gear 42 with the speed of the input shaft 6, we move the clutch 39 (E) to the left (L) position, connect the wide gear ring 41 with the gear crown 40 of the input shaft 6 (bottom view).

Torque is transmitted in the opposite direction compared to the first stage. The energy of the flywheel 62, 61 by the pressure disk 65, the inner gear ring 73 is supplied to the outer gear ring 76, the tubular shaft 75, the first row (s) of gears 11-16, the tubular shaft 20, the lower coupling 30 (C) from the wide gear ring 35 to ring gear 33, the third row (e) of gears 18-13, the tubular shaft 15 to the fourth row (f) of gears 14-19 and from the ring gear 28 by the coupling 25 (D), the force is transmitted to the ring gear 26 of the secondary shaft 7. Next, the frequency transformation rotation is carried out in the PM: from the secondary shaft 7 to the sun gear 51 (a), which rotates the satellites 50. Satellite 50, rolling around a stopped epicyclic wheel 52 (b), rotate the axis 49 and the carrier 46 (h), the force is transmitted through the tubular input shaft 45 to the fifth row (i) of gears 43-42, to the wide gear ring 41, by the coupling 39 ( E) on the ring gear 40, the input shaft 6 on the ring gear 60 and the coupling 5 (A) on the ring gear 4 of the ICE crankshaft 3, which receives energy with a significantly reduced rotational speed sufficient to start the ICE.

The gear ratio between the shaft flywheel 62, 61 and the crankshaft 3 will be

The frequency of rotation of the flywheel in comparison with the frequency of rotation of the drive shaft of the electric motor will decrease by almost 30 times.

The third stage - connecting the crankshaft to the flywheel

The energy of the flywheel spent on starting the internal combustion engine will reduce the speed of the flywheel 62, 61, the tubular shaft 63 and the ring gear 64. When the rotation speed of the ring gears 64 and 4 approaches, turn off the drive of the primary shaft 6 from gear 42, moving the coupling 39 (E ) to the neutral (H) position. By coupling 5 (A) we connect the gears 4 and 64 to each other (bottom view) - the crankshaft 3 and the flywheel 61, 62 with the pressure plate 65 rotate at the same frequency; we move the clutch disengaging clutch 69 towards the flywheel, disconnect the pressure disk 65 from the tubular shaft 75, opening the ring gears 73 and 76, engage the clutch by clamping the driven disk 59 between the drive disks 61 and 65 (lower clutch view). The electric motor 36, the input shaft 6 and the manual gearbox are disabled.

The fourth stage - gear shifting in the manual gearbox

In a sequential gear shift, clutch C (29 and 30) is triggered at each shift (see table. Fig. 2), clutch B (24) after two shifts, clutch D (25) after 4 shifts, and clutch F (77 ) - after 8 gear changes.

Starting an internal combustion engine with an electric inertia starter, which drives the flywheel through a drive to a high speed, does not require large electric motor and battery power.

With a change in K - the internal parameter PM and the gear ratios of the pairs of gears, the distribution of gear ratios over the range will change. By increasing the gear ratio of pairs of gears, you can reduce the number of accelerating gears for which the gear ratio is less than one. The redistribution of summing gears is possible, including with a change in the direction of rotation of the output shaft.
