Abstract
The utility model discloses a hub structure of a driving axle, and relates to a driving axle. The hub structure of the driving axle comprises a sun wheel, a planet wheel, a brake pad supporting wheel and a half axle, and is characterized in that one end of the sun wheel is connected with an outer spline of the half axle, the half axle is connected with an inner spline of the brake pad supporting wheel, and the half axle and a connecting end of the sun wheel jointly support the brake pad supporting wheel. The hub structure of the driving axle has the advantages that the hub structure is smooth in braking, low in abrasion, fine in radiating effect, high in braking torque capacity and long in service life, and is applicable to 8T loaders with heavy loads.
Description
Technical field
The utility model relates to a kind of drive axle, specifically is a kind of drive axle wheel limit structure.
Background technology
Homemade wet type drive axle wheel limit structure, sun wheel is a driving link, pinion carrier is a driven member, 3 planetary wheeling mechanisms.Sun wheel is that female splines is connected with semiaxis, and sun wheel is subject to factors such as hub size, planetary reduction gear ratio, the strength of gear teeth, structure, and the sun wheel size is less, and the semiaxis diameter of axle and structure are limited.Because domestic loader applying working condition is poor; Overload during certain customers use, semiaxis receives the impact load above normal value, and the semiaxis fracture accident often appears in drive axle; Because of the diameter of axle strengthens limited; Can only select the expensive material of price for use, the measures such as processing and Technology for Heating Processing that improve reduce semiaxis fracture failure situation, so structurally also there are some defectives in existing homemade drive axle.
Summary of the invention
The utility model is in order to remedy the deficiency of prior art, and a kind of intensity height, long service life, the bearing load ability is big, the braking torque amount is big drive axle wheel limit structure are provided.
The utility model comprises sun wheel, satellite gear, brake facing support wheel and semiaxis; Its special character is: an end of described sun wheel is connected with the semiaxis male splines; Described semiaxis is connected with brake facing support wheel female splines, the coupling end together support brake facing support wheel of described semiaxis and sun wheel.Sun wheel is a tooth axle integrative-structure, compares with existing structure, and this structure semiaxis length reduces; Under the identical situation of sun wheel number of teeth parameter, the semiaxis of this structure is bigger more than 15% than existing structure semiaxis axle journal, and can take into full account is that semiaxis overload etc. makes that semiaxis receives normally, ultra normal value impact load; Suitably add the major semiaxis axle journal, strengthen torque reserve, strengthen semiaxis intensity; Improve service life, can be good at solving the situation of semiaxis fracture failure.
Described satellite gear is 4.Adopt 4 planetary gear structures, the bearing load ability increases, and can satisfy the heavily stressed requirement of 8T loader better.
The beneficial effect of the drive axle of the utility model wheel limit structure: brake smooth-going, abrasion loss is little, good heat dissipation effect, braking torque capacity are big, long service life is suitable for 8T loader heavy duty use.
Description of drawings
Fig. 1 is the structural representation of the utility model;
The structural representation that Fig. 2 is connected mutually, decomposes for sun wheel, semiaxis and brake facing support wheel among Fig. 1;
Among the figure: 1, planet wheel spindle, 2, needle roller, 3, satellite gear, 4, sun wheel, 5, wheel hub, 6, planetary wheel carrier, 7, inner gear, 8, drg, 9, the brake facing support wheel, 10, semiaxis.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
Accompanying drawing is a kind of specific embodiment of the utility model; This embodiment comprises sun wheel 4, satellite gear 3, brake facing support wheel 9 and semiaxis 10; One end of described sun wheel 4 is connected with semiaxis 10 male spliness; Described semiaxis 10 is connected with brake facing support wheel 9 female spliness, the coupling end together support brake facing support wheel 9 of described semiaxis 10 and sun wheel 4.Described satellite gear 3 is 4.
The utility model in use, sun wheel 4 and semiaxis 10 are connected through male splines, compare with existing structure; These structure semiaxis 10 length reduce, and under the identical situation of sun wheel 4 number of teeth parameters, the semiaxis 10 of this structure is bigger more than 15% than existing structure semiaxis axle journal; Can take into full account is that semiaxis 10 overload waits and makes that semiaxis receives normally, ultra normal value impact load, suitably adds the major semiaxis axle journal, the increasing torque reserve; Strengthen semiaxis 10 intensity; Improve service life, better solved semiaxis 10 problem of fracture failure in use, satellite gear 3 becomes present 4 by original 3 simultaneously; The bearing load ability increases, and can satisfy the heavily stressed requirement of 8T loader better.
Claims (2)
