Technical field

The utility model relates to a kind of heavy axle differential mechanism, particularly a kind of heavy axle differential case bearing bracket.

Background technique

At present, its differential case bearing bracket of heavy truck bridge of domestic production all adopts split type, as shown in Figure 1, differential case bearing bracket comprises: with reducing gearbox, close the fixed bearing block 11 that is made as one, FE Tiler 12, by locating stud 14 and attachment bolt 13 with FE Tiler 12 and fixed bearing block 11 composition that links together.Adopt the differential case bearing bracket of this kind structure to need FE Tiler 12 in course of working and with reducing gearbox, close the fixed bearing block 11 that is made as one to be assembled together, need first to take apart in the vehicle bridge assembly process to ressemble differential case bearing bracket, the machining accuracy of differential case bearing bracket is difficult to guarantee consistent with assembly precision again.In there will be processing and assemble twice process through the differential case bearing bracket of dismounting again because attachment bolt 13 screw-down torque values are different, make FE Tiler 12 deform, cause the differential case bearing bracket hole to occur that thereby ellipticity error affects the bearing installation precision, and then affect product performance.

The model utility content

For the deficiencies in the prior art, the utility model aims to provide a kind of all-in-one-piece differential case bearing bracket, in the solution prior art, differential case bearing bracket, because of the different machining accuracies that produce of attachment bolt screw-down torque value and assembly precision inconsistence problems, is enhanced product performance and manufacturing efficiency when processing with assembling.

The utility model adopts Integral differential mechanism bearing support form, comprises the differential case bearing bracket main body, connects locating stud, bearing attachment face, bolt connecting hole.Differential case bearing bracket main body wherein, connect locating stud, bearing attachment face and bolt connecting hole are monolithic construction, connect locating stud on differential case bearing bracket main body top, the bearing attachment face is the annular inner surface of differential case bearing bracket main body, and bolt connecting hole is positioned on the base of differential case bearing bracket main body.

The utility model adopts Integral differential mechanism bearing support form, FE Tiler and fixed bearing block and locating stud are closed and be made as one, make bearing mounting hole become overall structure, reduced number of spare parts, avoided simultaneously significantly improving work efficiency and the machining accuracy of product because the attachment bolt secondary is tightened the differential case bearing bracket hole that causes and ellipticity error occurred.

Preferably, described differential case bearing bracket has 2 bolts hole on differential case bearing bracket main body base, with the locating stud that is connected on differential case bearing bracket main body top, forms triangle, and the differential case bearing bracket main body can obtain better fixed effect.

Preferably, described differential case bearing bracket is provided with ring shaped oil passage at the bearing attachment face, connect the locating stud center and be provided with oil channel hole, and this oil channel hole communicates with ring shaped oil passage, and lubricant oil is drained between bearing and differential case bearing bracket, has strengthened the bearing lubrication effect.

Preferably, described differential case bearing bracket is provided with oil baffle in the differential case bearing bracket both sides, and with the lubricant oil drainage, the oil that makes gear be thrown to down on oil baffle in working order can be back on gear, thereby improves the lubricating condition of the driving components such as gear.Different according to working state differential bearing sense of rotation or continuous working period, the oil baffle length of differential case bearing bracket both sides can be not identical.

More preferably, above-mentioned oil baffle and differential case bearing bracket main body angle be α and extend a segment distance L to differential case bearing bracket main body both sides, and α is that below 90 degree, extended distance L is greater than zero, and the distance L of extension depends on actual need and determines.Perhaps, this oil baffle and differential case bearing bracket main body angle are after α extends a segment distance L to differential case bearing bracket main body both sides, again with differential case bearing bracket main body angle, to extend to differential case bearing bracket main body both sides as β, α is below 90 degree, β is less than α, extended distance L is greater than zero, and the distance L of extension depends on actual need and determines.

The utility model provides a kind of all-in-one-piece differential case bearing bracket, avoided differential case bearing bracket processing and when assembling because of the different machining accuracies that produce of bolt tightening moment and assembly precision inconsistent, improve the lubricated environment of the driving components such as gear, promoted product performance and manufacturing efficiency.

Embodiment

Understand and realize the utility model for the ease of persons skilled in the art, now describing by reference to the accompanying drawings the utility model one specific embodiment.

As shown in Figure 2, the utility model differential case bearing bracket comprises, differential case bearing bracket main body 6 connects locating stud 2, ring shaped oil passage 3, bearing attachment face 4, oil baffle 5, bolt connecting hole 7.

Wherein, differential case bearing bracket main body 6 is annular overall structure; Ring shaped oil passage 3 is the annular grooves in differential case bearing bracket main body 6 loop configuration inboards; Connect locating stud 2 and be positioned at the top of differential case bearing bracket main body 6, and with differential case bearing bracket main body 6, close and be made as one, be used for be located by connecting differential case bearing bracket main body 6 and axle housing rear cover assembly.

As shown in Figure 2, connect the middle central oil passage hole 1 that comprises of locating stud 2.As shown in Figure 6, this central oil passage hole 1 communicates with the ring shaped oil passage 3 of bearing attachment face 4.Lubricant oil flows to ring shaped oil passage 3 by central oil passage hole 1, has strengthened the lubrication effect of bearing and differential case bearing bracket between bearing and differential case bearing bracket.

As shown in Figure 2, bolt connecting hole 7 is positioned on the base of differential case bearing bracket main body 6, by bolt, differential case bearing bracket main body 6 is connected with reducing gearbox.The number of this bolt connecting hole 7 can be for more than 2, and when the number of bolt connecting hole 7 was 2,2 bolt connecting holes 7 were fixed differential case bearing bracket with the connection locating stud 2 that is connected differential case bearing bracket main body 6 tops, can obtain best fixed effect.

As shown in Figure 2, oil baffle 5 closes and is made as one with differential case bearing bracket main body 6, is positioned at differential case bearing bracket main body 6 both sides.As shown in Figure 4, B-B line and C-C line parallel, in the present embodiment, oil baffle 5 is 70 degree and to differential case bearing bracket main body 6 both sides, extends the L distance with the angle α of differential case bearing bracket main body 6, extended distance L is 21mm, again take with differential case bearing bracket main body 6 angle β as 22.5 degree extend to differential case bearing bracket main body 6 both sides, being thrown to oil on oil baffle this moment, to be back to the gear effect best.Extended distance L is more approaching zero, and the gear oil effect of oil baffle is poorer, and extended distance L maximum value is subject to the heavy axle assembly and distributes to the maximum space restriction of differential case bearing bracket.

As shown in Figure 4, the differential case bearing bracket in the utility model embodiment, during due to working state, the differential mechanism Bearing gear continuous working period that turns clockwise is long, and the oil baffle 5 on differential case bearing bracket right side is long.
