Abstract
The utility model discloses a transaxle differential mechanism assembly, including differential mechanism body and central siphon, last casing and lower casing that the differential mechanism body is connected including mutually supporting, the differential mechanism is the internal cross axle that is equipped with originally, corresponds respectively on the armshaft of four outside extensions of cross axle to be connected with a planetary gear, is equipped with a lubricating oil oil duct between cross axle and the planetary gear, and in the armshaft of cross axle was located to a lubricating oil oil duct, the armshaft periphery was equipped with the armshaft annular that feeds through with a lubricating oil oil duct, differential mechanism body both ends all are equipped with an one end rather than fixed connection's central siphon, between central siphon and the differential mechanism body all the cooperation be connected an interior grommet, the utility model discloses preventing that the friction is too big between planetary gear and the corresponding differential side gear who uses, and then having improved transmission efficiency, root differential mechanism body is convenient to be connected with the central siphon of different length, and the assembly welds easy control.
Description
Technical field
The utility model relates to ransaxle field, specifically a kind of ransaxle differential assembly.
Background technique
Ransaxle is in the end of Power Train, its fundamental function be increase by transmission shaft or speed changer transmit turn, and power is reasonably distributed to left and right driving wheel, also bear in addition and act on vertical, longitudinal force between road surface, vehicle frame or vehicle body and transverse force.Ransaxle is generally made up of main reducing gear, differential mechanism, wheel drive and driving axle housing etc.The differential assembly of the truck ransaxle of current domestic production, drive connecting shaft and be connected simply between differential gear, the phenomenon that easily causes that connection comes off etc. under heavy duty and overload condition, integrity problem is larger, the lubrication effect of differential assembly is also poor simultaneously, has had a strong impact on the performance of differential mechanism; And existing differential mechanism poor universality, the diversity hardware and software platform demand of client can not be met.
Model utility content
The purpose of this utility model is to provide a kind of ransaxle differential assembly, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technological scheme:
A kind of ransaxle differential assembly, comprises differential mechanism body and central siphon, and described differential mechanism body comprises the upper shell and lower shell body that cooperatively interact and connect; Cross axle is provided with in described differential mechanism body, four outward extending armshafts of cross axle have been connected respectively a planetary pinion, be provided with lubricant oil between cross axle and planetary pinion and prop up oil duct, lubricant oil props up oil duct and is located in the armshaft of cross axle, armshaft periphery is provided with the armshaft annular groove propping up oil duct with lubricant oil and be communicated with, planetary inwall be provided with armshaft annular groove with the use of gear annular groove, be provided with the oil outlet be communicated with gear annular groove between the planetary gear teeth; Described differential mechanism body two ends are equipped with the central siphon that an one end is fixedly connected with it, and be all connected between central siphon and differential mechanism body an inner bushing ring.
Further, the left and right sides of described upper shell and lower shell body is arc transition structure.
Further, described upper shell and lower shell body are steel casting.
Compared with prior art, lubricant oil of the present utility model can be propped up oil duct and enter in corresponding planetary pinion by each lubricant oil distributed in cross axle, and discharged by oil outlet, planetary pinion and the corresponding differential gear used lubricate by the lubricant oil of discharging, excessive to prevent from rubbing between the two, and then improve transmission efficiency; As required, described differential mechanism body is connected with the central siphon of different length, and to adapt to the needs of various model, differential mechanism body is short, and the mould of processing differential mechanism body is little, and make differential mechanism body weld seam short, assembly welding is easy to control.
Accompanying drawing explanation
Fig. 1 is the structural representation of ransaxle differential assembly.
