Abstract
The utility model relates to a vehicle bridge differential device, in particular to an improved heavy duty vehicle bridge differential device. The utility model is characterized in that a half axle gear gasket is provided with grooves; a planet gear gasket is provided with drop pits, the drop pits are evenly distributed on the concave face of the planet gear gasket, and the maximum diameters of the drop pits are smaller than 5 mm; the grooves are arranged on both sides of the half axle gear gasket, and arranged along the radial direction of the surface of the gasket, and the number of the groove is not less than two. The differential device improved according to the proposal is characterized in that because grooves which can be used for storing lubricating oil and drop pit structures are respectively arranged on the surfaces of two gaskets, and compound brass material with good self-lubricating function and thermal conductivity is adopted, the frictional resistance among a half axle gear, a planet gear, and the left half casing and the right half casing of the differential device is obviously reduced and the heat radiation of the differential device is improved. The structure of the utility model is simple and reasonable, and the utility model is the beneficial and effective improvement.
Description
Technical field
The utility model relates to vehicle axle differential mechanism, especially about a kind of improved heavy-duty car axle differential.
Background technique
Be provided with the differential gear planetary pinion in traditional heavy-duty car axle differential, wherein, between left and right half shell of left and right half gear and differential mechanism respectively device pad is arranged, and between planetary pinion and differential left half shell also device pad is arranged.The purpose of device pad is in order to reduce friction and to improve running efficiency.Present case is that these two pads generally all are to adopt carbon constructional quality steel, and handle through carburizing quenching process.But actual situation is that the pad of this kind structure exists the defective that frictional resistance is big, noise reaches the weak point in working life greatly in running.
The model utility content
The purpose of this utility model is for overcoming existing defective in existing axle differential differential gear pad and the planetary pinion gasket construction, proposing a kind of improved heavy-duty car axle differential.For realizing that this purpose adopts following technological scheme: a kind of improved heavy-duty car axle differential, comprise differential gear pad and planetary pinion pad, it is characterized in that the differential gear pad is provided with groove; The planetary pinion pad is provided with pit, and pit evenly is laid in the concave surface of planetary pinion pad, and the maximum diameter of pit is less than 5mm; Groove is located at the two sides of differential gear pad, and groove is along the radially setting of gasket surface, and the number of groove is no less than 2, and the flute profile of groove is trapezoidal or semicircle; Differential gear pad and planetary pinion pad all adopt the composite brass material to make.
Press the improved heavy-duty car axle differential that such scheme is implemented.Owing to be provided with groove and the bowl configurations that to store lubricant oil respectively on the surface of two kinds of pads, and adopted and have well from the composite brass material of profit effect and thermal conductivity, more significantly reduce the surface friction drag between left and right half shell of differential gear, planetary pinion and differential mechanism and improved the heat radiation of differential mechanism.The utility model structure is simple and direct rationally, is a kind of useful and effective improvement.
Description of drawings
Fig. 1 is the structural representation of the utility model in the axle differential assembly;
Fig. 2 is the perspective view of the utility model differential gear pad;
Fig. 3 is the concave structure schematic representation of the utility model planetary pinion pad.
Embodiment
Connect with accompanying drawing and be described in further detail.The utility model comprises differential gear pad 5 and planetary pinion pad 3, and the two sides of differential gear pad 5 punching out respectively has 4 by radially-arranged trapezoidal groove 51,52 (shown in the dotted line), and the flute profile of groove also can be made semicircle; The groove 51 and 52 on pad two sides is preferably made staggered.In the utility model, described differential gear pad 5 and planetary pinion pad 3 all adopt the composite brass material punching out with good self-enrichment and heat-conducting property to form,
The sphere thin slice that planetary pinion pad 3 punching out one-tenth and planetary pinion 4 big end spheres match is meanwhile gone out the spherical pit 30 that several are evenly laid in the concave surface of pad 3, the maximum diameter on pit 30 surfaces is 3mm..When the utility model is installed in the axle differential assembly of Fig. 1, between left half axle gear 8 and differential left half shell 1 and right axle shaft gear 7 and right half shell 6 of differential mechanism, install the differential gear pad pad 5 among Fig. 2 respectively, between 4 planetary pinions 4 and left and right half shell 1 of differential mechanism, installed the planetary pinion pad 3 among 4 Fig. 3 respectively.When differential mechanism in when operation, scribble brazen planetary pinion pad 3, the differential gear pad 5 of lubricant oil, owing to be provided with groove 51,52 and the pit 30 that to deposit lubricant oil, pad can better reduce surface friction drag, reduction noise, the reduction maintenance frequency of differential mechanism inside and improve transmission efficiency when making running, and the working life that prolongs the vehicle axle differential mechanism assembly.
