Description

VEHICLE POWER INSTALLATION

The useful model belongs to the field of mechanical engineering and can be used in power plants of forklifts, graders, trucks, etc. cars.

A propulsion system of a vehicle is known, comprising an engine, a clutch, a gearbox and a connecting unit between the shafts of the clutch and gearbox, made in the form of a cardan transmission. An independent power take-off drive shaft is placed concentrically in the hollow shafts of the gearbox clutch, the shaft passes through a cardan drive consisting of a first end fork, an intermediate fork and a second end fork provided with central holes. The engine and gearbox are mounted on the machine frame independently of each other (1).

The closest in technical essence and the achieved result to the proposed solution is the power plant of the loader, comprising a motor connected via an elastic coupling and gear reducer of the pump drive to the transmission gearbox, which is connected through the transfer gearbox and cardan drives to the axles of the vehicle (2).

several options with different engines and gearboxes. In particular, a truck gearbox may be mounted on the loader. At the same time, in order to fit into the existing machine configuration the borrowed gearbox, it is necessary to make design changes in it, which is undesirable.

In addition, it is technologically difficult to ensure the alignment of the engine and transmission in two planes. This is especially difficult when it is necessary to install shock-absorbing cushions under the engine and transmission.

These shortcomings are eliminated by the fact that the known power plant of a transnational vehicle, comprising an engine connected via an elastic coupling and a gearbox of the pump drive to the transmission gearbox, which is connected to the axles of the vehicle via cardan drives, is additionally equipped with a double-jointed cardan shaft, a pump drive gearbox, which is

matching, made five-sided, its first shaft is connected to the engine flywheel, the third - through an additional driveshaft with a gearbox, the output shaft of which is connected directly to the cardan drives with axles, and the fourth and fifth gear shafts are connected to the pumps of the vehicle.

Distinctive features of the claimed device is that the installation is additionally equipped with a two-jointed cardan shaft, the drive gear of the pumps, which is matching, is made five-shaft, its first shaft is connected to the flywheel

engine, the third through an additional driveshaft - with a gearbox, the output shaft of which is connected to cardan drives with bridges directly, and the fourth and fifth shafts of the gearbox are connected to the pumps of the vehicle.

Therefore, the claimed combination of features is new, i.e. the patentability condition of the novelty utility model is fulfilled.

The presence of an additional two-hinged cardan shaft, as well as the matching of the pump drive gearbox and the fifth gear, so that its first shaft is connected to the engine flywheel, the third through an additional cardan shaft with a gearbox, the output shaft of which is connected directly to the cardan drives, and the fourth and fifth gear shafts

connected to the pumps of the vehicle, allows you to install the transmission of the truck on the truck without its alteration. In addition, the engine and transmission can be mounted on cushion pads, which increases the reliability of the machine.

The essence of the utility model is illustrated by the drawings: figure 1 shows the kinematic diagram of the power plant of the vehicle;

figure 2 is a view And figure 1 is an enlarged image of the gear drive the pumps.

L The gearbox 7 of the transmission is connected by a double-jointed universal joint shaft 8 with the rear axle 9 and the universal joint drive 10 - with a non-intermediate axle 11 of the vehicle. Reducer 3 nrnvoda pumps made nativny and is simultaneously matching gear. Its first shaft 12 is connected to the flywheel of the engine 1, through the clutch 2, the third shaft 13 is connected by an additional two-joint cardan shaft 14 with a torque converter 4 and a transmission gearbox 7. The fourth 15 and fifth 16 shafts of the gearbox 3 are connected to the pumps 5 and 6 of the transport means, respectively. The device operates as follows. The torque of the engine 1 through the elastic coupling 2, the shafts 12 and 13 of the gearbox 3 is transmitted using the driveshaft 14 to the torque converter 4 and the transmission gearbox 7. The pumps 5 and 6 are driven by shafts 15 n 16 of the gearbox 3. From the gearbox 7, the torque is transmitted by the driveshaft 8 and the driveshaft 10 to the bridges 9 and 11. Thus, when the borrowed car gearbox is mounted on a loader, the power plant elements are connected with each other using double-jointed cardan shafts 8.14 and cardan drive 10.

engine mountings n transmission. This increases the reliability of the vehicle.

The implementation of the gearbox of the five-pump drive allows you to install a borrowed gearbox without structural changes.
