Description

MOVING MACHINE.

(54) HAVING A SPLIT DRIVE

one

This invention relates to a driving mechanism for self-propelled tracked vehicles.

A single-bucket excavator undercarriage is known, which includes a frame, final drives and a drive for each track, consisting of an engine and a brake, mounted on gearbox 1.

Also known is a running gear that includes a frame, side gears in a separate drive of each track, consisting of a motor with a shaft located perpendicular to the longitudinal axis of the excavator gear with driving gears and driven wheels, intermediate shafts and brakes 2 J.

The drawback of the device is low reliability due to the occurrence of significant dynamic loads in the drive of the propulsion unit, which is caused by the non-simultaneous selection of gaps in the gears of the gearbox while simultaneously turning on the Motors and

as a result, the asynchronous action of the loads that cause the car to turn when it is strained also from its place.

11el of the invention - reliability by means of synchronous operation of the drives

The goal is achieved by the fact that in the traveling mechanism of self-propelled machines, imek dih separate drive, including the frame of the undercarriage, leading

10 wheels connected to the output shafts of the gearboxes and drive motors mounted on the gearbox housings, the latter are pivotally mounted on the frame of the undercarriage and connected with it by

ts cylinder cylinders whose like cavities are interconnected by themselves.

Claims (2)

The Running Mechanism contains drivers 1. frames 2, drive wheels 3 connected to output shafts 4 of gearboxes 5, drive shishigatel 6, hydraulic heads 7 mounted on frames 2, rods 8 of which are pivotally connected to housings of reducers 5. Equal cavities of hydraulic heads 7 connected in closed tours and filled with working fluid. The device works as follows. With the simultaneous switching on of both drive motors 6, the gaps in the gears of the gearbox 5 are selected non-simultaneously. One of the drive motors 6, for example, the left, will previously choose gaps in the transmission gear 5, than the second, right. As a result, earlier you perceive the load and begin to rotate in the hinge relative to frame 2, affecting the rod 8 of the left hydraulic cylinder 7. At the same time, the working fluid is displaced from it and injected into the same cavity of the right-sided shnindra 7. the right gear 5 and accelerate the choice of loans In-his transfer. After this, both drives come into operation simultaneously and with the same load. The application of the invention provides a reduction in the level of dynamic loads in the transmission and drives, and thus allows to increase the reliability of the running mechanism. Claims of the invention The running gear of self-propelled machines, imec cnx separate drive, including the frame of the undercarriage, drive wheels connected to the output shafts, gearboxes, and drive motors installed. on gearbox housings differing in hem, that in order to increase reliability by synchronizing the operation of the drives, gear housings are pivotally mounted on the frame of the undercarriage and connected with it by means of hydraulic shafts, the cavities of the same name are interconnected.
