Description
Technical field
The utility model relates to a kind of Novel wheel-side retarder, belongs to wheel reductor technical field.
Background technique
At present in the general arrangement of heavy truck, full-sized bus, engineering machinery vehicle, need to make the assemblies such as gearbox, transfer case, transmission shaft can not make because bearing large torque the size of these parts and quality excessive, and need large as far as possible for velocity ratio ratio to distribute to ransaxle.But, general axle main speed reducer is difficult to reach above-mentioned requirements, therefore the ransaxle of many heavy-duty cars, full-sized bus, engineering machinery adopts the layout of single-stage (or twin-stage) main reducing gear additional wheel side reducer again, to obtain large reduction speed ratio and compact structure.Because wheel reductor belongs to power train end, gear bears comparatively high pulling torque and impulsive load, thus the bearing between connected row star-wheel and planet wheel shaft can only improve the bearing capacity of wheel reductor by increasing bearing size, and be often subject to the restriction of bearing installing space, bearing capacity and installing space are become be difficult to for a pair the contradiction balanced, kind of bearings procurement cycle is long simultaneously, manufacture is complicated, cause the raising on O&M cost, and the bearing of Lack of support will directly have influence on performance and the working life of wheel reductor.
Traditional wheel reductor is as the NGW wheel reductor specified in standard JB/T6502-1993, planet wheel adopts and is evenly arranged form, on the one hand due to uniform needs, the mathematical relationship that sun gear, planet wheel and gear ring number of teeth demand fulfillment are certain, cause the velocity ratio monotony of wheel reductor, on the other hand, due to uniform relation, planet wheel quantity is restricted, thus is difficult to the bearing capacity improving wheel reductor when retarder boundary dimension is constant.Therefore, how when wheel reductor boundary dimension is constant, improving its bearing capacity is people's problem demanding prompt solutions.
Summary of the invention
The deficiency that the utility model exists for prior art and defect, providing a kind of when wheel reductor boundary dimension is constant, can improve the Novel wheel-side retarder of its bearing capacity.
For achieving the above object, the technological scheme that the utility model adopts is: a kind of Novel wheel-side retarder, comprise casing, be arranged at the input shaft in casing, sun gear, planet wheel, planet carrier, gear ring and end cap, described input shaft is provided with described sun gear by spline, described planet carrier is provided with multiple planet wheel shaft, planet wheel shaft is provided with the planet wheel of bearings, described planet wheel be positioned at sun gear peripheral and simultaneously with sun gear and gear ring engagement driving, also sleeve is provided with between described planet wheel and bearing, described sleeve is fixed in the mounting hole at planet wheel center, and be tight fit connection with bearing outside surface, described end cap is positioned at casing rear and is connected with casing, offers annular groove inside this end cap, installs snap ring in annular groove.
In above-mentioned Novel wheel-side retarder, described casing one end is provided with the link for connecting brake drum, the end face of the other end offers input shaft bore and planet wheel axis hole, and is provided with multiple stiffening rib in casing.
In above-mentioned Novel wheel-side retarder, described input shaft is male splined shaft, and its external splines end is connected with the external splines end of sun gear by inner spline housing.
In above-mentioned Novel wheel-side retarder, between described snap ring and end cap interior edge face, be also provided with oil baffle disc.
In above-mentioned Novel wheel-side retarder, the number of bearings in described sleeve is a plurality of, is separated between each bearing by spacer, and described spacer is cylindrical tube shape.
The beneficial effects of the utility model are:
1, sleeve is provided with between the utility model wheel reductor planet wheel and planet wheel shaft, in sleeve, multiple bearing is installed, moment of torsion suffered by bearing and the impulsive load of planet wheel and support planet wheel are shared by sleeve, thereby increase the bearing capacity of wheel reductor, life-saving;
2, the end cap of the utility model wheel reductor box back effect that can play attract dust to the gear in wheel reductor and bearing and prevent dust from entering, reduces the wearing and tearing of wheel reductor inside, extends its working life;
Be provided with multiple stiffening rib in the casing of 3, the utility model wheel reductor, improve casing intensity, not easily deform, effective the prevents the leakage of oil caused because of wheel reductor box deformation;
4, the utility model is reasonable in design, compact structure, is easy to production and processing, and operation and maintenance cost is low, is easy to promotion and implementation.
