Description
Technical field
The utility model relates to the service brake technical field of engineering machinery, specifically is the wet brake of a kind of semiaxis and wheel hub Associated brake.
Background technique
The wet multi-disc brake braking is adopted in the service brake of engineering machinery now more, with respect to dry brake, wet multi-disc brake is fully closed, and elements such as braking plate, friction plate and brake piston are installed in the brake casing, can avoid the influence of outside moisture, dust, impurity etc.In addition, the active force of wet brake piston is equally distributed, and hydraulic coupling and the linear variation relation of formed braking force, so service brake is rapid, and has higher Security, and long service life.
Present wet brake mainly contains two kinds of modes of braking of semiaxis braking and wheel hub braking.The semiaxis mode of braking has the little advantage of physical dimension, and shortcoming is the break back owing to closely follow gear transmission, and has the gap between the gear pair, and when causing skidding, vehicle rocks easily, and braking is unstable; The wheel hub mode of braking is because the annular working area is big, and hydraulic coupling that can be less obtains bigger braking moment, thereby it is big to have braking moment, the vehicle dead advantage of easily stopping, and shortcoming is that required friction plate is many, the radial structure size of break is bigger.In addition, present wet brake arrestment mechanism mostly is normally closed working method, and this kind working method advantage is to satisfy the stopping brake of engineering machinery vehicle, but brings problems such as brake is anxious, buffering is poor, goods that load easily flies out when practical application.
Summary of the invention
The anxious shortcoming of brake when the big and arrestment mechanism of radial structure size was normally closed working method when the wheel hub braking was easily rocked, adopted in brake when adopting the semiaxis braking in order to solve existing wet brake, the utility model provides the wet brake open in usual of a kind of semiaxis and wheel hub Associated brake, under the situation of identical piston action power, braking moment obtains increasing, and has solved problems such as the brake of normally closed mechanism is anxious, buffering is poor, goods that load easily flies out simultaneously.
The utility model is realized with following technological scheme: the wet brake of a kind of semiaxis and wheel hub Associated brake, fix an end axle for supporting wheel hub at vehicle frame, on the end axle service brake piston and gear ring support are installed, have turnover oil duct and venting road in the end axle, air relief cock also is installed and passes in and out oily joint on the end axle; Axially displaceable platen, a plurality of push rod and gear ring that is symmetrically distributed vertically are housed in the gear ring support; The static friction sheet is installed on the gear ring; End axle, gear ring support and gear ring are connected into one; Also comprise a planetary wheel carrier and wheel carrier shell, planetary wheel carrier, wheel carrier shell and wheel hub are connected into one; End cap, planet axis and brake pad are installed on the planetary wheel carrier, planet wheel is installed on the planet axis, brake pad is marked closely on planetary wheel carrier by housing screw; Semiaxis is equipped with movable friction plate by splined one braking hub on the braking hub; This wet brake arrestment mechanism is normally open.
The beneficial effects of the utility model are:
(1) during service brake owing to adopted semiaxis and wheel hub Associated brake, under the constant situation of piston thrust and physical dimension, braking moment obtains increase, the shortcoming of having avoided the unitary system flowing mode to bring simultaneously;
(2) since parking braking change in the gearbox and finish, so this wet brake is in the vehicle Parking and when normally travelling, arrestment mechanism is often opened, that is: braking component such as piston, push rod, Returnning spring are the non-stress state, dynamic and static friction plate separates, simplify the structure of wet brake like this, prolonged the life-span of wet brake, solved problems such as the brake of normally closed mechanism is anxious, buffering is poor, goods that load easily flies out;
(3) brake member of this wet brake and planetary gears have been made one, so reduced the number of parts of wheel limit assembly, have reduced cost of production.

Embodiment
Shown in Fig. 1-4, the wet brake of semiaxis and wheel hub Associated brake, fix an end axle 15 for supporting wheel hub 14 at vehicle frame, on the end axle 15 service brake piston 13 and gear ring support 17 are installed, have turnover oil duct 22 and venting road 23 in the end axle 15, air relief cock 20 is installed and passes in and out oily joint 21 on the end axle 15; Mobile vertically platen 18, a plurality of push rod 12 and gear ring 16 that is symmetrically distributed vertically are housed in gear ring support 17; Static friction sheet 9 is installed on the gear ring 16; End axle 15, gear ring support 17 and gear ring 16 are connected into one; Also comprise a planetary wheel carrier 7 and wheel carrier shell 8, planetary wheel carrier 7, wheel carrier shell 8 and wheel hub 14 are connected into one; End cap 2, planet axis 5 and brake pad 19 are installed on the planetary wheel carrier 7, planet wheel 1 is installed on the planet axis 5, brake pad 19 is marked closely on planetary wheel carrier 7 by housing screw 6; Semiaxis 3 is equipped with movable friction plate 10 by splined one braking hub 4 on the braking hub 4; This wet brake arrestment mechanism is normally open.
In the present embodiment, platen 18 is installed on the gear ring support 17 by 4 SOC.HD. cap screws, on 4 SOC.HD. cap screws Returnning spring 11 is housed all.
The gear ring supporting structure as shown in Figure 5 and Figure 6.
The platen structure as shown in Figure 7 and Figure 8.
Planetary wheel carrier structure structure such as Fig. 9 and shown in Figure 10.
Working procedure: when vehicle travelled, power was through semiaxis 3 inputs.When semiaxis rotated, because the semiaxis left end is gear (being sun gear) structure, so drive planet wheel 1 rotation, planet wheel 1 drove planetary wheel carrier 7 revolution simultaneously, because gear ring 16 and end axle 15, gear ring support 17 are connected into one, so gear ring 16 does not change; Because planetary wheel carrier 7, wheel carrier shell 8 and wheel hub 14 are connected into one, so the wheel hub rotation, the wheel that is contained on the wheel hub rotates thereupon again.
When vehicle travels the needs braking, pressure oil enters through turnover oil duct 22 by fuel inlet fitting 21, promote brake piston 13 to left movement, brake piston 13 promotes push rod 12, push rod 12 promotes platen 18 again, the platen 18 final static friction sheets 9 that promote are pressed on the movable friction plate 10, rely on frictional force to produce braking.
During service brake, static friction sheet 9 compresses (under the effect of piston thrust) mutually with the movable friction plate 10 that is installed on the braking hub 4 on the one hand, and braking hub 4 connects with semiaxis by spline, thereby has realized the semiaxis braking; On the other hand, a slice on the movable friction plate 10 is pressed on the brake pad 19, because brake pad 19 is marked closely on planetary wheel carrier 7, and planetary wheel carrier 7, wheel carrier shell 8 and wheel hub 14 have been connected into one, like this, braking force passes to wheel carrier shell 8 by planetary wheel carrier 7, and wheel carrier shell 8 is passed to braking force wheel hub 14 again, thereby has realized the wheel hub braking.
When vehicle does not need to brake, the solenoid directional control valve commutation in the oil hydraulic circuit, platen 18 resets under Returnning spring 11 effects, and the sound friction plate separates, and hydraulic oil is through 22 oil returns of turnover oil duct, normal vehicle operation simultaneously.
