Abstract

The utility model relates to a novel wheel side wet brake with a composite structure, consisting of a transition disc, a driving friction plate, a driven friction plate, an inner gear, a piston, a semiaxis, a guide ring, a supporting shaft, an inner gear hub and an O-shaped ring, wherein, inner teeth of the driving friction plate is engaged with outer teeth of the transition disc; inner teeth of the transition disc are engaged with outer teeth of the semiaxis; outer teeth of the driven friction plate are engaged with inner teeth of inner gear on the wheel side; outer teeth of the piston are engaged with inner teeth of the inner gear; the O-shaped ring seals between the supporting shaft and the inner gear hub; and the guide ring is arranged on the leftmost end of the piston. Due to adoption of the structure, the brake torque is small; the wheel side structure is simple; the sealing is good; and no leakage occurs.

Description

A kind of novel limit wet brake of taking turns of composite structure
Technical field
The utility model relates to a kind of wheel limit wet brake that is applied to a kind of composite structure on the engineering machinery ransaxle, and it utilizes high pressure oil pressing friction sheet to interrupt the moment of torsion transmission and realizes braking, the general function of Returnning spring brake off.
Background technique
At present, wheel limit wet brake mainly is when complete machine travels, and the high pressure oil that comes from oil duct promotes piston, with the master in the break, driven friction compress, in conjunction with and interrupt the moment of torsion transmission, the disengagement of friction plate is to lean on the active force of Returnning spring in the break that piston is pushed back, and braking is removed.Wheel limit wet brake generally is divided into two kinds, a kind of semiaxis for the braking speed end, a kind of planet carrier or wheel hub for braking low speed end, existing domestic ransaxle wheel limit wet braking is generally the braking of low speed end, be equipped with simple seal form, low speed end braking braking torque is big, wheel limit complex structure, seals badly, has leakage phenomenon.
Summary of the invention
The purpose of this utility model provides that a kind of braking torque is little, the novel limit wet brake of taking turns of simple in structure, the good seal in wheel limit, the composite structure that do not leak.
The purpose of this utility model is achieved in that by transition disc, active friction plate, forms from movable friction plate, ring gear, piston, semiaxis, guide ring, back shaft, ring gear wheel hub, O type circle, the internal tooth of active friction plate and the engagement of transition disc external tooth, the transition disc internal tooth meshes with the semiaxis external tooth again, from the external tooth of movable friction plate and the ring gear internal tooth engagement on wheel limit, piston external tooth and the engagement of ring gear internal tooth, adopt the sealing of O type circle between back shaft and ring gear wheel hub, the piston high order end is installed a guide ring.
Because the utility model adopts said structure, braking torque is big, the wheel limit is simple in structure, good seal, do not leak.
Description of drawings
Fig. 1 is a structural drawing of the present utility model.
Fig. 2 is the partial enlarged drawing of I among Fig. 1.
Fig. 3 is the load chart of Fig. 2
1 planet carrier among Fig. 1,2 sun gears, 3 planet wheels, 4 ring gears, 5 transition discs, 6 active friction plates, 7 Returnning springs, 8 are from movable friction plate, 9 pistons, 10 ring gear wheel hubs, 11 guide rings, the 12 pairs of delta seal circles, 13 O type circles, 14 semiaxis, 15 back shafts.
Embodiment
Embodiment: by transition disc 5, active friction plate 6, form from movable friction plate 8, ring gear 4, piston 9, semiaxis 14, guide ring 11, back shaft 15, ring gear wheel hub 10, O type circle 13, the internal tooth of active friction plate 6 and the engagement of transition disc 5 external tooths, and transition disc 5 internal tooths mesh with semiaxis 14 external tooths, thereby active friction plate 6 rotates with semiaxis 14, from the external tooth of movable friction plate 8 and fixing wheel limit ring gear 4 internal tooths engagement, piston 9 external tooths also mesh with ring gear 4 internal tooths simultaneously.During braking, the high pressure oil of bringing in from back shaft 15, ring gear wheel hub 10 promotes piston 9, this moment, Returnning spring 7 was compressed, and after piston 9 compressed driving and driven friction plate, power was then through semiaxis 14, transition disc 5, active friction plate 6, interrupt from movable friction plate 8, ring gear 4.After the complete machine braking was removed, high pressure oil then returned along former oil duct, and Returnning spring 7 elastic force then push back piston 9, and driving and driven friction plate separates, and power is then again through semiaxis 14, sun gear 2, planet wheel 3, planet carrier 1 output.In this process, no matter having, break do not have combination, and driving and driven friction plate all is immersed in the wheel side gear oil, and heat radiation and lubricating condition are better.
Static seal between back shaft 15 and ring gear wheel hub 10 adopts 13 sealings of 2 road O type circles, the ladder piston is the ladder form, in have high pressure oil to adopt the novel seal form, two delta seals 12 are shown in partial enlarged drawing I, this pair triangle is made up of O shape circle and seal ring, its mechanism of action such as Fig. 3, after build-up pressure, seal ring is pressed one side of groove, tightly fluid is kept off on one side, prevent the appearance of leakage situation, played good seal action.Piston 9 high order ends have been installed a guide ring 11, and its effect is as follows: 1, play the guiding role with the motion of piston external tooth for piston; 2, absorb the radial force that produces at any time, stop the infringement of radial force, prevent to leak two delta seal circles 12; 3, prevent direct contact of metal (piston) and metal (ring gear wheel hub); 4, have certain dustproof effect, can prevent that impurity in the gear oil is to the damage of two delta seal circles 12.

Claims (1)

1, a kind of novel limit wet brake of taking turns of composite structure, by transition disc, active friction plate, form from movable friction plate, ring gear, piston, semiaxis, guide ring, back shaft, ring gear wheel hub, O type circle, it is characterized in that: the internal tooth of active friction plate and the engagement of transition disc external tooth, the transition disc internal tooth meshes with the semiaxis external tooth again, from the external tooth of movable friction plate and the ring gear internal tooth engagement on wheel limit, piston external tooth and the engagement of ring gear internal tooth, adopt the sealing of O type circle between back shaft and ring gear wheel hub, the piston high order end is installed a guide ring.
