Abstract
The utility model discloses a cross axle suspension type differential device which comprises a planet wheel, a half-axle wheel, a cross axle, a differential shell and a driven bevel gear, wherein the planet wheel is connected with the half-axle wheel through a bearing; the cross shaft is formed by independently supporting four short shafts, each short shaft is provided with an oil guide hole, and a lubricating loop is formed between the cross shaft and the planet wheel; the cross shaft is connected with the right differential shell through threads; when the half shaft of the vehicle is damaged, the half shaft can be effectively taken out; the lubrication hole is added in the cross shaft, so that good lubrication can be realized under various working conditions when a vehicle runs; in addition, the cross shaft is connected with the shell through threads, so that the cross shaft is firmer.
Description
Technical Field
The utility model relates to the technical field of commercial axles, in particular to a cross axle suspension type differential device; the device is used for special vehicles such as road transport vehicles, tractors, van vehicles and light dump trucks.
Background
The conventional commercial vehicle axle adopts a long and short shaft structure, when a vehicle runs, after a half shaft serving as a vehicle fuse is broken, the vehicle cannot be taken out, and only an axle housing can be damaged to be taken out, so that the cost is high, and the market influence is severe; the cross shaft and the planet are lubricated by a gap between the cross shaft and the planet, and the fault of abnormal abrasion can occur; the cross shaft is limited by the gear, and has a gap, so that axial movement can occur, and the service life is seriously influenced.
SUMMERY OF THE UTILITY MODEL
The present invention is directed to overcoming the above-mentioned deficiencies of the prior art and providing a spider-suspended differential.
The technical scheme provided by the utility model is as follows: a cross axle suspension type differential device comprises a differential left shell, a half axle wheel, a differential right shell, a driven bevel gear, a cross axle and a planet gear; the differential left shell supports a half-axle wheel, and is connected with the differential right shell and a driven bevel gear; the cross shaft is connected with a right differential shell, the planet wheel is sleeved on the cross shaft, and the axle is axially supported by the half axle wheel; the universal joint pin is characterized in that the universal joint pin is formed by independently supporting four short shafts, each short shaft is provided with an oil guide hole, and a lubricating loop is formed between the universal joint pin and the planet wheel.
Preferably, the cross shaft is in threaded connection with the right differential shell.
The utility model has the beneficial effects that:
1. according to the requirements of vehicle maintenance and replacement of damaged half shafts, the four short shafts are adopted and have independent structures, so that when the half shaft of the vehicle is damaged, the half shaft can be effectively taken out, and effective replacement can be realized under the condition that any part is not damaged;
2. the lubricating oil holes are added to the cross shaft, so that abnormal abrasion of the cross shaft and the planet in the market is reduced, a lubricating system can form a loop through the oil holes, impurities can be effectively removed, and good lubrication can be realized under various working conditions when a vehicle runs;
3. by adopting the threaded connection structure of the cross shaft and the shell, the axial movement of the cross shaft is effectively prevented, and the cross shaft is firmer.

FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is an enlarged view of a portion of FIG. 1;
fig. 3 is a schematic view of the lubrication circuit of the present invention.
Detailed Description
For a better understanding and appreciation of the utility model, reference will now be made in detail to the following description taken in conjunction with the accompanying drawings.
As shown in fig. 1, 2 and 3, the cross axle suspension type differential device is composed of a differential left shell 1, a half axle wheel 2, a differential right shell 3, a driven bevel gear 4, a cross axle 5 and a planet gear 6; the differential left shell 1 supports a half-axle wheel 2, and the differential left shell 1 is connected with a differential right shell 3 and a driven bevel gear 4 through bolts; the cross shaft 5 is connected to the right differential shell 3 through threads, the planet wheel 6 is sleeved on the cross shaft 5 and is axially supported by the half axle wheel 2; the cross shaft 5 is formed by independently supporting four short shafts, and each short shaft is provided with an oil guide hole, so that an effective lubricating loop 7 can be formed between the cross shaft 5 and the planet wheel 6; the cross shaft 5 is connected with the right differential case 3 by threads 8.
According to the cross shaft suspension type differential device, the differential function of the vehicle is realized through the differential mechanism, and when a half shaft of the vehicle is damaged, the half shaft can be effectively taken out; the lubrication hole is added in the cross shaft, so that good lubrication can be realized under various working conditions when a vehicle runs; in addition, the cross shaft is connected with the shell through threads, so that the cross shaft is firmer.
It should be understood that technical features not described in detail in the specification belong to the prior art. Although the embodiments of the present invention have been described with reference to the accompanying drawings, the present invention is not limited to the above embodiments, which are only illustrative and not restrictive, and those skilled in the art can make various modifications without departing from the spirit and scope of the utility model as defined by the appended claims.
