Abstract
The utility model relates to the technical field of a brake and particularly discloses a wet brake. The wet brake comprises a brake drum, a bottom plate and a hub sleeved in the brake drum; a ring-shaped cavity is formed between the brake drum and the hub; the bottom plate is fixedly connected with the bottom of the brake drum; an oil inlet hole is arranged in the bottom plate; a check ring, a brake disc and a piston are sequentially arranged in the ring-shaped cavity; the brake disc comprises a steel sheet and a friction plate which are arranged at intervals; the steel sheet is connected with the inner wall of the brake drum through a spline; the friction plate is connected with the outer wall of the hub through a spline; a spring is arranged between the piston and the bottom plate; two Y-shaped rings are arranged on the outer side of the piston; a hydraulic oil cavity communicated with the oil inlet hole is formed between the two Y-shaped rings; and a floating oil seal is also arranged between the brake and the hub. The wet brake has the benefit that when the wet brake is applied to the service brake of a vehicle, the problem of brake failure caused by fault of a brake hydraulic system can be completely solved.
Description
Technical field
The utility model relates to the break technical field, relates in particular to a kind of wet brake.
Background technique
Present wet brake commonly used is to have compacting moving, that is to say when to break hydraulic pressure being provided and brakes, and this mode of braking, brake failure will occur, even major accident takes place during like situation such as oil circuit obstruction or pipeline ruptures when oil path failure occurring.And use the security requirement meeting of break higher for special occasions such as railless free-wheeled vehicles under the coal mine.Therefore need a kind of break of decompression braking, perfectly safe to guarantee the vehicle braked performance, do not receive the influence of hydraulic system catastrophic failure in other words.Though on this type car, be useful on the decompression break of Parking at present, this decompression break can't directly be used for service brake because structure is limit.
The model utility content
The technical problem that the utility model will solve provides a kind of novel wet brake, to solve the ad hoc requirement of mining rubber-tired cart to the break Security.
The technological scheme that the utility model solves the problems of the technologies described above is following: a kind of wet brake, and comprise brake drum, base plate and be sleeved on the wheel hub in the said brake drum, between said brake drum and wheel hub, form toroidal cavity; Said base plate is fixedly connected on the bottom of said brake drum; Said base plate is provided with oil inlet hole, is characterized in, in said toroidal cavity, is disposed with back-up ring, braking plate and piston; Said braking plate comprises steel disc and the friction plate that the space is provided with; Said steel disc is connected through spline with the inwall of said brake drum, and said friction plate is connected through spline with the outer wall of said wheel hub, is provided with spring between said piston and the said base plate; The outside of said piston is provided with two Y-shaped rings, forms the hydraulic fluid chamber that is communicated with said oil inlet hole between said two Y-shaped rings.
Also be provided with float grease seal between said break and the wheel hub.
Be provided with hub bearing in the said wheel hub.
The beneficial effect of the utility model is: owing to adopt the decompression braking, can thoroughly solve the brake failure problem that breaks down and cause owing to brake hydraulic system.

Embodiment
Below in conjunction with accompanying drawing the principle and the characteristic of the utility model are described, institute gives an actual example and only is used to explain the utility model, is not the scope that is used to limit the utility model.
As shown in Figure 1, a kind of wet brake comprises brake drum 3, base plate 10 and is sleeved on the wheel hub 1 in the said brake drum 3; Between said brake drum 3 and wheel hub 1, form toroidal cavity, said base plate 10 is fixedly connected on the bottom of said brake drum 3, and said base plate 10 is provided with oil inlet hole 11; It is characterized in that; In said toroidal cavity, be disposed with back-up ring 5, braking plate and piston 8, said braking plate comprises the steel disc 6 and friction plate 7 that the space is provided with, and said steel disc 6 is connected through spline with the inwall of said brake drum 3; Said friction plate 7 is connected through spline with the outer wall of said wheel hub 1; Be provided with spring 9 between said piston 8 and the said base plate 10, the outside of said piston 8 is provided with two Y-shaped rings 16, forms the hydraulic fluid chamber that is communicated with said oil inlet hole 11 between said two Y-shaped rings 16.
Also be provided with float grease seal 2 between said break 3 and the wheel hub 1.
Be provided with hub bearing in the said wheel hub 1.
Be provided with O type circle 15 between said base plate 10 and the brake drum 3.
Said hub bearing comprises angular contact bearing 14 and tapered roller bearing 17.
One end of said wheel hub also is provided with oil sealing seat ring 12 and oil sealing 13.
The working principle of the utility model is, during use this break is installed on the vehicle axle housing 4, through hub bearing wheel hub 1 and axle housing 4 is rotatably connected, and through tire bolt hole 19 usefulness tire bolts wheel hub 1 is connected with wheel.When hydraulic oil got in the oil pocket of said two Y-shaped rings 16 through oil inlet hole 11, high pressure oil promoted piston 8 and moves to base plate 10 directions, and piston 8 breaks away from braking plate, and promptly steel disc 6 is in disengaged position, brake off with friction plate 7; When brake, hydraulic oil can be back to hydraulic system through oil inlet hole 11, relies on spring 9 pressure, promote piston 8 and move to the braking plate direction, and extruding steel disc 6 makes it extruding with friction plate 7 and is one, makes car brakeing.
The above is merely the preferred embodiment of the utility model, and is in order to restriction the utility model, not all within the spirit and principle of the utility model, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
