Description

Vehicle bridge bronze adjustment pad

Technical field

The utility model relates to field of automobile brake, is specifically related to a kind of vehicle bridge bronze adjustment pad.

Background technique

The vehicle bridge of automobile is the load for bearing automobile, and maintains the normal traveling of automobile on road.Vehicle bridge is connected with vehicle frame by suspension.

In the vehicle-bridge system of automobile, there are more parts usually, be interconnected by gear, bearing etc. between its all parts, and carry out the transmission of driving torque, its all parts is moved mutually.

Interaxial differential wherein in vehicle bridge, owing to being subject to larger frictional force effect, as gear shaft and gear carried out directly contacting, can causing gear shaft and gear failure, causing the damage of interaxial differential.Under normal circumstances, be all between gear shaft and gear, set up adjustment pad to bear the frictional force between gear shaft and gear.

But, currently used adjustment pad adopts Steel material or alloy steel material to make usually, but because Steel material and alloy steel material have stronger hardness, therefore, it can produce certain friction chip after larger frictional force, and the chip that rubs can touch the parts such as gear, bearing in vehicle bridge accordingly, finally cause the spot corrosion of gear, bearing etc., infringement, the serious working life affecting interaxial differential in vehicle bridge.

Therefore, how to design a kind of frictional force can effectively born between axle components, and ensure speed differentiator between vehicle-bridge shafts have compared with the long life vehicle bridge adjustment pad just become thing urgently to be resolved hurrily.

The technical solution of the utility model is:

A kind of vehicle bridge bronze adjustment pad, is characterized in that, comprising:

Adjustment shim body, it has cirque structure;

Lubrication groove, lubrication groove is four, the upper surface being arranged on adjustment shim body symmetrical respectively and lower surface;

Adjustment shim body adopts bronze material to make.

Preferably, the degree of depth of lubrication groove is 0.5mm.

Vehicle bridge bronze adjustment pad of the present utility model has the following advantages:

(1) the adjustment pad adopting bronze material to make has good wear resistance, effectively can improve the working life of speed differentiator between vehicle-bridge shafts, and extend the service cycle of vehicle;

(2) the adjustment pad adopting bronze material to make is after generation wearing and tearing, and the friction chip hardness of generation is lower, effectively can reduce friction chip to the infringement of miscellaneous part in vehicle bridge;

(3) by arranging lubrication groove on adjustment pad, further can reduce the frictional force that adjustment pad is subject to, increasing its working life.

Accompanying drawing explanation

Fig. 1 is the use figure of the utility model vehicle bridge bronze adjustment pad embodiment.

Fig. 2 is the structural drawing of the utility model vehicle bridge bronze adjustment pad embodiment.

Embodiment

For making the purpose of this utility model, technological scheme and advantage clearly, below in conjunction with the accompanying drawing in the utility model embodiment, technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.

As depicted in figs. 1 and 2, in figure, each reference character is specially, and 1 is input bead, and 2 is active cylindrical gear shaft, 3 is the first pressing bearing, and 4 is adjustment shim body, and 5 is active cylindrical gear shaft, 6 is cross assembly, and 7 is rear bevel gear, and 8 is that the second pressing bearing, 41 is for lubrication groove.

As shown in Figure 1, the vehicle bridge bronze adjustment pad of the present embodiment, comprising:

Adjustment shim body 4, it has cirque structure;

Lubrication groove 41, lubrication groove 41 is four, the upper surface being arranged on adjustment shim body symmetrical respectively and lower surface;

Adjustment shim body adopts bronze material to make.

Concrete, adjustment shim body 4, for having cirque structure, is made by bronze material; Adjustment shim body 4 being provided with lubrication groove 41, for being formed for the loop of lubricating liquid flow in adjustment shim body 4, ensureing that adjustment shim body 4 effectively reduces friction the damage caused it in the course of the work.

Wherein, the lubrication groove 41 be arranged in adjustment shim body 4 has four, and respectively two lubrication grooves 41 are arranged at the upper surface of adjustment shim body 4, two lubrication grooves 41 are arranged at the lower surface of adjustment shim body 4, further, two lubrication grooves 41 be arranged on the upper surface adjusting shim body 4 or lower surface are symmetrical in the centerline of adjustment shim body 4.

The degree of depth of lubrication groove 41 is 0.5mm.

Further, lubrication groove 41 adopts the mode of machine tooling to realize, and effectively can ensure the machining accuracy of lubrication groove 41, improves the service behaviour of adjustment pad.

Further, four lubrication grooves 41 be arranged at respectively in adjustment shim body 4 are incomplete circle structure, and it only occupies the portion in adjustment shim body 4, and the shape of four lubrication grooves 41, size are identical.

As shown in Figure 2, be the use figure of the vehicle bridge bronze adjustment pad of the present embodiment, shown in Fig. 2, clearly can draw in the present embodiment the use position adjusting pad, and usage mode.

The concrete using process of the vehicle bridge bronze adjustment pad in the present embodiment is as follows:

(1) adjustment shim body 4 is sleeved in active cylindrical gear shaft 2;

(2) in active cylindrical gear shaft 2, initiatively cylindrical gears 5 is loaded;

(3) on the both sides of active cylindrical gear shaft 2, installing the first pressing bearing 3 and 8 respectively additional is the second pressing bearing;

(4) finally cross assembly 6 and rear bevel gear 7 are installed in active cylindrical gear shaft 2, finally to form interaxial differential.

The working procedure of concrete interaxial differential is:

When there is moment of torsion input in input end, the moment of torsion of transmission shaft passes to initiatively cylindrical gear shaft 2 by inputting bead 1, initiatively cylindrical gear shaft 2 is connected with cross assembly 6 by spline, initiatively cylindrical gears 5 and rear bevel gear 7 are connected to initiatively in cylindrical gear shaft 2 as two output terminals of interaxial differential, realize the differential of penetrating bridge and back axle.

When input end exists input torque, initiatively there is relative movement with active cylindrical gears 5 in cylindrical gear shaft 2, bears axial friction by adjustment shim body 4.

Because adjustment shim body 4 adopts bronze material to make, its wear resistance is better, the gear clearance of the more effective adjustment interaxial differential of energy.

It is simple that vehicle bridge bronze adjustment pad of the present utility model has structure, use advantage easily, the adjustment pad adopting bronze material to make has good wear resistance, effectively can improve the working life of speed differentiator between vehicle-bridge shafts, and extend the service cycle of vehicle; The adjustment pad adopting bronze material to make is after generation wearing and tearing, and the friction chip hardness of generation is lower, effectively can reduce friction chip to the infringement of miscellaneous part in vehicle bridge; By arranging lubrication groove on adjustment pad, further can reduce the frictional force that adjustment pad is subject to, increasing its working life.

The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make and suitably improving and distortion, these improve and distortion also should be considered as protection domain of the present utility model.
