Description
Technical field
The utility model relates to brake system of car technical field, and more particularly, it relates to a kind of wet brake.
Background technique
At present, the application of engineering vehicle is increasingly extensive, and engineering vehicle General Requirements carrying capacity is comparatively large, or working environment is comparatively severe, therefore, also higher to the requirement of braking system.Automotive brake is as important parts, be the Focal point and difficult point of Car design, existing automotive disc brake, has braking moment and stablizes always, heat resistanceheat resistant damping capacity is strong, but disk type braker is dry brake, its shortcoming is that friction area is little, heat radiation is slow, operating temperature is high, operationally easily produces spark, can not use under such as ore deposit factory etc. requires high environment.Therefore, the break of wet type obtains the favor of automobile production producer, and, in recent years along with the requirement that the raising required braking ability and various working environment adapt to, artificer, by updating, makes every effort to the wet brake studying and design a kind of function admirable, long service life.
Model utility content
The purpose of this utility model is to provide a kind of novel wet brake, can solve existing shoe type, caliper disc, multi-disk wet brake Problems existing, and braking effect is desirable, life-span is long, anti-adverse environment factor capability of influence is strong, and braking reliability is high, to overcome the deficiencies in the prior art.
For solving the problems of the technologies described above, the utility model discloses a kind of wet brake, comprise break drive end, arrester shell, brake cap, movable friction plate, static friction sheet, described break drive end connects wheel hub, movable friction plate is arranged on break drive end by spline, static friction sheet is arranged on arrester shell by spline, metallic mirror surface oil sealing is provided with between break drive end and arrester shell, brake piston is arranged on arrester shell inside, brake cap arranges two brake fluid force feed turnover oilholes, brake piston seal ring is provided with between arrester shell and brake piston, piston packing is provided with the oil channel structures passing in and out oilhole with described brake fluid force feed and be communicated with, arrester shell arranges some grooves, return spring is arranged in groove.
Described brake cap connects axle housing, arrester shell connecting brake lid.
Described return spring is four, uniform in cross.
Described brake fluid force feed turnover oilhole is separated by 180 degree of layouts.
Known by said structure, the utility model has following beneficial effect:
Wet brake working stability of the present utility model, anti-adverse environment factor capability of influence is strong, can automatic regulating brake gap, and adopt totally enclosed type braking, its braking moment is large, high temperature resistant, no-spark, adapts to complex working condition, ensures the driving safety of vehicle.
Adopt metallic mirror surface oil sealing, double-deck oil sealing before and after this oil sealing adopts, wear resistance is good, and oil sealing is effective, and the life-span is long.
Wet brake of the present utility model is by pressurized oil braking, and reset use four return spring plugs, return spring plug symmetry is distributed on break inner chamber, good braking effect.Oil inlet and outlet on arrester shell adopts Redundancy Design, facilitates user to select, to adapt to different vehicle chassis oil pipe arrangements.
Accompanying drawing explanation
Fig. 1 is wet brake structural representation of the present utility model.
Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment
Be described below in detail embodiment of the present utility model, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Being exemplary below by the embodiment be described with reference to the drawings, only for explaining the utility model, and can not being interpreted as restriction of the present utility model.
As shown in Figure 1-2, wet brake break drive end 2 of the present utility model is bolted on wheel hub 1; With spline on break drive end 2, movable friction plate 5 is arranged on break drive end 2 by spline; Vehicle in the process of moving, follow together with wheel hub 1 and rotate by break drive end 2 and movable friction plate 5.Brake cap 4 and spindle nose 11 are bolted on axle housing 12, and arrester shell 3 is bolted on brake cap 4, and with spline on arrester shell 3, static friction sheet 6 is arranged on arrester shell 3 by spline.Break drive end 2 and arrester shell 3 are equipped with metallic mirror surface oil sealing 7 respectively.Brake piston 9 is arranged on that arrester shell 3 is inner, and brake piston seal ring 10 is arranged between arrester shell 3 and brake piston 9, and piston packing is provided with the oil channel structures passing in and out oilhole with described brake fluid force feed and be communicated with.Brake cap arranges two brake fluid force feeds turnover oilhole 13, two brake fluid pressure oil turnover oilholes to be separated by 180 degree of layouts.One of them turnover oilhole is optional, and the Chassis vitta according to different automobile types is arranged, can select brake fluid force feed turnover oilhole the most suitable.Arrester shell arranges some grooves, and return spring is arranged in groove.Return spring is four, uniform in cross.
When stepping on brake, hydraulic oil enters the oil channel structures on piston packing under the driving of oil pump by the brake fluid force feed turnover oilhole of on brake cap, oil pressure is about 14Mpa, powerful pressure will promote brake piston 9, brake piston 9 promotes static friction sheet 6, static friction sheet 6 pressed against movable friction plate 5, thus produces braking action; During braking, the return spring 8 in groove is compressed, and when releasing of brake, hydraulic fluid pressure reduces, and return spring 8 is by brake piston 9 pushed home.
Although illustrate and described embodiment of the present utility model; those of ordinary skill in the art is to be understood that: can carry out multiple change, amendment, replacement and modification to these embodiments when not departing from principle of the present utility model and aim; scope of the present utility model limited by claim and equivalent replacement thereof; in the improvement etc. done without creative work, all should be included within protection domain of the present utility model.
