Background technology
At present, the drive axle using on loader generally adopts dry-type caliper disc brake.Brake disc is exposed to outside all the time, because be very easily stained with the pollutantss such as mud, very easily affect braking effect, when drg operation simultaneously, frictional area is little, make compressive load per unit area high, heat-resisting quantity, strength character to friction plate material have all proposed higher requirement.Friction lining radiating effect is poor, and seal ring is very easily aging, occurs the faults such as leakage of oil.
Summary of the invention
The utility model discloses a kind of wet-type braking driving axle, its radiating effect that has solved original dry brake existence is poor, and seal ring is very easily aging, the problem of appearance leakage of oil etc., has braking reliability high, compact conformation, low cost of manufacture, the advantage that lock torque is large.
The utility model is achieved through the following technical solutions:
Disclosed wet-type braking driving axle in the utility model, comprise axle centre housing, the two ends of axle centre housing are provided with left axle housing, right axle housing, on left axle housing, right axle housing, be equipped with wheel reduction gear, the main driving assembly that wheel reduction gear is provided with axle centre housing respectively by left half axle, right axle shaft is connected, in described main driving assembly, be also provided with oil-immersed multi-disk brake, left half axle, right axle shaft lay respectively in left axle housing, right axle housing.
Say further, main driving assembly described in the utility model is connected with left half axle, right axle shaft by castellated shaft.
Say further, oil-immersed multi-disk brake described in the utility model comprises piston, friction lining, driven disc, pull back spring, on axle centre housing, be provided with hydraulic fluid port, a side at piston is provided with friction lining, driven disc, the two ends of friction lining, driven disc are respectively equipped with pull back spring, are provided with D RunddichtringO between piston and axle centre housing.
Say further, the wet-type braking driving axle described in the utility model is symmetrical structure.
Compared with prior art, the utlity model has following beneficial effect:
1, the utility model adopts hermetically-sealed construction, and brake strip group is bathed in oil, perfect heat-dissipating, and the ability of cope with bad working environment is strong;
2, good braking environment of the present utility model extends the friction lining life-span in the utility model relatively;
3, the utlity model has high, the compact conformation of braking reliability, low cost of manufacture.The feature that lock torque is large;
4, adopt the sealing of D type circle, be applicable to crank motion, can prevent distortion by actv..

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
Embodiment 1: a kind of wet-type braking driving axle, described wet-type braking driving axle is symmetrical structure, it comprises axle centre housing 10, the two ends of axle centre housing 10 are provided with left axle housing 2, right axle housing 7, on left axle housing 2, right axle housing 7, be equipped with wheel reduction gear 1, the main driving assembly 5 that wheel reduction gear 1 is provided with axle centre housing 10 respectively by left half axle 3, right axle shaft 6 is connected, in described main driving assembly 5, be also provided with oil-immersed multi-disk brake, left half axle 3, right axle shaft 6 lay respectively in left axle housing 2, right axle housing 7; Described main driving assembly 5 is connected with left half axle 3, right axle shaft 6 by castellated shaft 4; Described oil-immersed multi-disk brake comprises piston 9, friction lining 12, driven disc 13, pull back spring 14, on axle centre housing 10, be provided with hydraulic fluid port 8, be provided with friction lining 12, driven disc 13 in a side of piston (9), the two ends of friction lining 12, driven disc 13 are respectively equipped with pull back spring 14, between piston 9 and axle centre housing 10, are provided with D RunddichtringO 11.
In conjunction with above-described embodiment, principle of work of the present utility model is: hydraulic oil enters between piston 9 and axle centre housing 10 by hydraulic fluid port 8, and the confined space being formed by D RunddichtringO 11 produces certain pressure, makes piston 9 promote vertically friction lining 12.Friction lining 12 and the driven disc 13 being fixed between left axle housing 2 and axle centre housing 10 produce rubbing effect, a part for friction lining 12 and castellated shaft 4(semiaxis) one end is connected, and then produces brake action.In the time that input pressure reduces, be distributed on pull back spring 14 between left axle housing 2 and axle centre housing 10 and promote piston 9 and force return, friction lining 12 is separated with piston 9.
The braking point of its wet-type braking driving axle adopting of the utility model is on semiaxis, and semiaxis is two sectional type structure, passes through spline joint; Friction lining 12 in the utility model infiltrates in bridge bag transmission oil the inside always, is conducive to better heat radiation; Sealing adopts D type circle sealing 11, is applicable to crank motion, can effectively prevent distortion, and the groove taking is less, makes structure compacter.
