Abstract
The utility model discloses a direct connecting device for a power take-off unit and a gear pump of a dump truck. The device comprises a flange connecting body with bolt connecting holes, wherein the flange connecting body is arranged between the power take-off unit and the gear pump through bolts, and is provided with an accommodation cavity; and a first coaxial coupling, a second coaxial coupling and a third coaxial coupling are arranged in the accommodation cavity, and are connected with one another through keys, and torque can be transferred among the first, second and third coaxial couplings. The conventional transmission shaft connection and hanger suspension connection modes for the gear pump are replaced by a direct connection transmission mode, only a set of transmission connecting body is required to be arranged between the power take-off unit and the gear pump, and the first, second and third coaxial couplings are connected with one another through keys, so that the transmission efficiency is greatly improved, cost is effectively lowered, and the device is simple in structure, safe and reliable.
Description
Technical field
The utility model relates to automotive field, is specifically related to a kind of dumping car power take-off and the direct-connected device of gear pump.
Background technique
Present dump truck dumping car power take-off is connected with gear pump, and having mainly is to pass through Cardan shaft.Transmission shaft linkage structure complexity, volume is big, the cost height, quality is big, is not easy to dress during repacking and arranges and install.Therefore, a kind ofly can guarantee transmission, can realize gentlyer, easier again that direct-connected device has been extremely urgent more efficiently.
Summary of the invention
At the deficiency that prior art exists, technical problem to be solved in the utility model is, a kind of Cardan shaft and volume is little, in light weight, cost is low, simple in structure and safe and reliable dumping car power take-off and direct-connected device of gear pump of replacing is provided.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of dumping car power take-off and the direct-connected device of gear pump, comprise by bolt and be installed in the flange connecting body with bolt connecting hole between power take-off and the gear pump, described flange connecting body has a holding cavity, but in holding cavity, be provided with the first coaxial shaft joint, the second coaxial coupling and the 3rd coaxial coupling of driving torque each other, all connect by key between the described first coaxial coupling, the second coaxial coupling and the 3rd coaxial coupling.
Above-mentioned dumping car power take-off and the direct-connected device of gear pump, the described first coaxial coupling inner peripheral surface is provided with first spline that links to each other with power take-off, outer peripheral surface is provided with the 3rd spline that is connected with second spline fitted of the second coaxial coupling inboard, outer peripheral surface at the 3rd coaxial coupling is provided with the 4th spline that links to each other with the 3rd spline, and the inner peripheral surface of described the 3rd coaxial coupling is provided with five spline adaptive with the gear pump rotating shaft.
The utility model dumping car power take-off with the advantage of the direct-connected device of gear pump is: gear pump is connected by original transmission shaft and the hanger suspending Placement changes direct connection transmission into, overlap the body that is in transmission connection as long as between power take-off and gear pump, install one, all connect by key between the first coaxial coupling, the second coaxial coupling and the 3rd coaxial coupling, improved the efficient of transmission greatly, this linkage structure is simple, effectively reduce cost, and safe and reliable.
