Abstract
The utility model provides a planetary gear of a wheel-side speed reducing mechanism used for a heavy-duty automobile, which has the advantages of high intensity and long service life. The planetary gear adopts the technical proposal that the modulus of the planetary gear is 4.0 mm to 5.0 mm, and the width of the tooth surface is 55 mm to 65 mm.
Description
Technical field
The utility model relates to the planetary pinion of a kind of heavy-duty car with the hub reduction mechanism of hub reduction bridge.
Background technique
At present, at heavy truck, in the general arrangement of large-bus, for make assemblies such as gearbox, transfer case, transmission shaft not reason bear excessive torque and make their size and quality excessive, can distribute to ransaxle by the ratio that velocity ratio is big as far as possible.The inaccessible requirement of main reducing gear of general structure, so many heavy-duty cars, large-scale bus often adopts the structure of single-stage (or twin-stage) main reducing gear additional wheel side reducer, a part of reduction speed ratio of ransaxle distributed to be installed in the middle of the wheel hub or nearby wheel reductor, thereby obtain bigger ratio coverage and the good performance of passing through.
Wheel reductor adopts two types of planetary gear type and common cylinder gear types usually.The planetary gear type wheel reductor is owing to taken turns the spatial constraints of end structure, the modulus of planetary pinion and sun gear and face width of tooth are all less, but the power of motor increases to turn round through the deceleration of gearbox and main reducing gear and is delivered to the wheel end, and through the planetary gear train driving wheel of wheel reductor, therefore planetary pinion causes planetary early stage damage easily with transfer larger torque.
Summary of the invention
Problem to be solved in the utility model is to overcome the planetary above-mentioned deficiency of wheel reductor, under wheel end spaces structure condition of limited, by reasonable Arrangement, provide a kind of intensity height, life-span long, can satisfy the planetary pinion of the hub reduction mechanism that heavy-duty car uses.
The technical solution of the utility model is: the hub reduction mechanism planetary pinion that heavy-duty car is used is characterized in that: planetary modulus is 4.0～5.0mm, and the face width of tooth is 55～65mm.
Adopt above technological scheme,, make the planetary intensity of hub reduction mechanism and life-span that very big lifting be arranged, can satisfy and block heavily that load-carrying is big, the needs of traffic condition difference owing to adopted the design of big modulus and the wide flank of tooth.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1, the planetary pinion of hub reduction mechanism adopts big modulus m=4.0～5.0mm and wide flank of tooth b=55～65mm project organization.
