Abstract
The utility model discloses a built-in multi-disk wet type brake, which comprises a sun wheel, a support plate (1) and a piston (3), wherein a friction device is arranged between the support plate (1) and the piston (3); the friction device comprises at least two drive friction plates (2); a driven plate (5) is arranged between every two drive friction plates (2); and the drive friction plates (2) and the driven friction plate (5) are tightly pressed together during braking. During use of the technical scheme of the utility model, pressure oil pushes the piston (3) to tightly press the drive friction plates (2) and the driven plate (2) so that the drive friction plates (2) and the driven plate (2) can brake the sun wheel together; the device has stable work performance, large brake force moment, good cooling effect, smooth braking and maintenance convenience, and increases the safety performance.
Description
Technical field
The utility model relates to a kind of ransaxle device, is specifically related to a kind of built-in multidisc wet brake that is applicable to the loader ransaxle.
Background technique
In the ransaxle brake field of loader, what generally use at present is dry type clipper disk brake or single friction plate wet brake, and its main structure comprises housing, sun gear, support plate and piston, is provided with single friction plate between support plate and the piston.This scheme is significantly improved with respect to the dry type caliper disc brake, as has solved the dry type caliper disc brake in braking process, and the piston return is not thorough, produces high temperature and causes the friction plate performance degradation, reduces the problem in working life.In addition, wet brake can not produce spark in use, makes engineering machinery such as loader not receive environmental limits such as place, weather in use.
But along with the development of engineering machinery, single friction plate wet brake can not be satisfied the demand, as has problems such as braking moment is little, braking effect is bad.
The model utility content
The utility model has overcome the deficiency of existing technology, provides that a kind of braking moment is big, the built-in multidisc wet brake of good braking effect.
For solving above-mentioned technical problem, the utility model adopts following technological scheme:
A kind of built-in multidisc wet brake; Comprise sun gear, support plate, piston and housing; Be provided with rubbing device between support plate and the piston; Above-mentioned rubbing device comprises at least two active friction plates, is provided with driven plate between said per two active friction plates, and active friction plate and driven plate are pressed on and brake sun gear together during braking.
Compared with prior art, the beneficial effect of the utility model is:
In the utility model technological scheme; Pressure oil promotes piston pressing friction device during braking; Active friction plate and driven plate are pressed on brakes sun gear together, and this device stable work in work, braking moment are big, good cooling results, braking is smooth-going and easy to maintenance, has improved Safety performance.
Description of drawings
Fig. 1 is the utility model structural representation.
Wherein, the pairing name of the reference character in the accompanying drawing is called:
The 1-support plate, 2-active friction plate, 3-piston, 4-housing, 5-driven plate.
Embodiment
Below in conjunction with accompanying drawing the utility model embodiment is done to specify further, but the mode of execution of the utility model is not limited thereto.
As shown in Figure 1; A kind of built-in many friction plate structures of wet brake comprise sun gear, support plate 1, piston 3 and housing 4, are provided with rubbing device between support plate 1 and the piston 3; This rubbing device is positioned at housing 4 inside; Above-mentioned rubbing device comprises two active friction plates 2 and driven plate 5, and above-mentioned driven plate 5 is arranged between two active friction plates 2, and two active friction plates 2 are pressed on together with driven plate 5 during braking.
Only described active friction plate 2 in the present embodiment and be two situation, when being other sheet when counting, its Placement is identical with working principle, promptly enumerate embodiment no longer separately and describe.
Built-in many friction plate structures of the wet brake of this mode of execution in use, pressure oil promotes piston pressing friction sheet 2 and driven plate 5 braking sun gears, thereby reaches the purpose of braking.
Present specification is the improvement that proposes to the active friction plate in the wet brake 2, changes existing single friction plate into two or multi-disc active friction plate 2 and is pressed on structure together with driven plate 5, its objective is the increase braking moment, makes braking effect better.
Through the description of present embodiment, just can better realize the utility model.
