Abstract
The invention provides a separable front axle driving structure of an excavator, which relates to an excavator. The invention is characterized in that the other end of the output shaft of a lower transmission box is extended with a spline shaft and fixed with a front axle transmission box. The front axle transmission box consists of a box body, a mainshaft, a flange, a bearing, a sliding connecting sleeve, a shifting fork and an operation device; the mainshaft is sheathed on the two bearings which are fixed on a shell bearing seat; the mainshaft and the output shaft of the lower transmission box have the same central line; one end of the mainshaft is the spline shaft which has small spacing with the spline shaft which is extended by the output shaft of the lower transmission box; the splines have the same dimension; the other end of the mainshaft is the flange; the spline shaft of the mainshaft is movably sheathed in a sliding connecting sleeve; the internal round of the sliding connecting sleeve is movably matched with the spline shaft; the external round of the sliding connecting sleeve is provided with a circular concave trough which is movably sheathed in the shifting fork; the other end of the shifting fork is fixed on the operation device. The invention has the advantages that the front axle adopts a clutch structure, therefore the front axle can be linked and separated, and the operation is convenient; the front axle can be disconnected or connected according to working condition sites; the structure is simple and the cost is low.
Description
Technical field:
The present invention relates to excavating machine, be specially adapted to the preceding bridge driving mechanism of excavating machine.
Prior art:
The mini-excavator crawler body is to give change speed gear box by the diesel engine transmission at present, makes it to drive for forward and backward bridge by change speed gear box by the auxiliary gear box transmission again.Mechanism like this, its structure bulky complex, operation inconvenience.
Another kind of structure is: the mini-excavator crawler body is that the upper gear box, the underdrive case that by change speed gear box, only play the space transfer function successively by diesel engine are given back axle with power transmission, driving rear axle, and this kind structure propons does not have propulsive effort.Its weak point is only to have rear-axle drive, in case road conditions are poor, when the gradient is big, the excavating machine walking is ineffective.
Summary of the invention:
The objective of the invention is to overcome above-mentioned weak point, a kind of excavator separable front axle driving structure is provided.
The solution of the present invention is that the other end at underdrive case output shaft stretches out a castellated shaft, fixes a propons transmission gearbox in this end correspondence.This propons transmission gearbox is made up of casing, main shaft, flange, bearing, sliding block joint cover, shift fork, handling device, main brass is on two bearings, bearing fixing is on the housing shaft bearing, main shaft and the same line of centers of underdrive case output shaft, one end of main shaft is a castellated shaft, this castellated shaft is separated by with the little gap of castellated shaft that following biography case output shaft stretches out, and spline is measure-alike; The other end of main shaft is a flange, and kink a sliding block joint cover on the main spindle multiple spline axle, circle and castellated shaft running-fit in the sliding block joint cover, and sliding block joint cover cylindrical has individual ring groove, and kink shift fork on this ring groove, and the shift fork other end is fixed on the handling device.
The invention has the advantages that: mini-excavator adopts the underdrive case to connect the propons drive mechanism, rear-axle drive before realizing, simultaneously, propons adopts clutch configuration, but realizes that the propons interlock is separable, under the off working state, propons separates, easy to operate, simultaneously road conditions poor, when the gradient is big, propons interlock then, walking is strong, ground, the next visual field of working condition excavates operating mode propons is broken away from or interlock, and this mechanism structure is simple, cost is low.
Description of drawings:
Accompanying drawing is a structural representation of the present invention.
The specific embodiment:
Mechanism of the present invention is that the other end at underdrive case (1) output shaft stretches out a castellated shaft (8), fixes a propons transmission gearbox in this end correspondence.This propons transmission gearbox is made up of casing (2), main shaft (7), flange (6), bearing, sliding block joint cover (3), shift fork (4), handling device (5), main shaft (7) is enclosed within on the two bearings, bearing fixing is on the housing shaft bearing, main shaft (7) and the same line of centers of underdrive case (1) output shaft, one end of main shaft (7) is a castellated shaft, this castellated shaft is separated by with the little gap of castellated shaft (8) that following biography case output shaft stretches out, and spline is measure-alike; The other end of main shaft (7) is flange (6), kink a sliding block joint cover (3) on main shaft (7) castellated shaft, circle and castellated shaft running-fit in the sliding block joint cover (3), sliding block joint cover (3) cylindrical has individual ring groove, kink shift fork (4) on this ring groove, and shift fork (4) other end is fixed on the handling device (5).
Handling device (5) can be pneumatic, surge, electromagnetism, manual variety of way.
Pneumatic mode is that a cylinder chamber is set in the propons transmission gearbox, and the piston rod end in the cylinder and the fixed end of shift fork (4) are fixed, and cylinder is realized plumbing connection with pressure gas again.
Hydraulic way is: a cylinder chamber is set in the propons transmission gearbox, and the fixed end of in-oil cylinder piston rod end and shift fork (4) is fixed, and oil cylinder is realized plumbing connection with pressure oil again.
The electromagnetism flowing mode is that an electromagnet is captiveed joint with shift fork (4) fixed end.
Manual mode is that an end of hand lever is captiveed joint with shift fork (4) fixed end.
Underdrive case (1) output shaft is connected with back axle, and propons transmission gearbox flange (6) is connected with propons, rear-axle drive before realizing.
During work, if when needing propons to drive, then handling device (5) action, make sliding block joint cover (3) slippage forward, be inserted in the castellated shaft (8) of underdrive case (1) one end, then the output shaft of underdrive case (1) simultaneously power transmission is successively given propons transmission gearbox main shaft (7), flange (6), with flange (6) bonded assembly propons, thereby drive propons.
If do not need propons to drive, then handling device (5) makes shift fork (4) slippage backward, sliding block joint cover (3) and underdrive case (1) castellated shaft (8) is disengaged then can.
