Detailed Description
Embodiments of the present invention are described in detail below, and the embodiments described with reference to the drawings are exemplary.
An outer shell 1 of an axle according to an embodiment of the present invention is described below with reference to fig. 1-2. The housing 1 of the axle is the basic component for mounting the final drive, the differential, the half shafts, the wheel hub and the suspension. The shell 1 of the axle has the main functions of bearing and bearing load change or impact caused by the mass transfer of the whole vehicle when various working conditions are changed or multiple working conditions simultaneously occur; and the other one is used for supporting and protecting a main speed reducer, a differential mechanism, a half shaft, a brake and the like, and is a tail end supporting and protecting component of a transmission system and a braking system.
As shown in fig. 1, the housing 1 of the axle according to the embodiment of the present invention may include: casing 2, end cover 3 and sealing washer 4, casing 2 are provided with installation opening 6, and end cover 3 is provided with collar 7, and end cover 3 can mutually support with casing 2, easy to assemble.
Moreover, the sealing ring 4 is a rectangular sealing ring 4, that is, the cross section of the sealing ring 4 is rectangular, and the structure is simple. Compared with a sealing ring with an O-shaped cross section in the prior art, the sealing ring 4 can increase the effective sealing area and improve the sealing performance when the shell 2 and the end cover 3 are matched, so that the reliability of the shell 1 of the axle can be improved.
According to an embodiment of the present invention, as shown in fig. 2, the outer peripheral wall of the mounting ring 7 is provided with a limiting groove 5, and a portion of the sealing ring 4 located at the radial inner side is disposed in the limiting groove 5, that is, a small portion of the inner ring of the sealing ring 4 is accommodated in the limiting groove 5, so that the sealing ring 4 can be firmly limited in the limiting groove 5. From this, through setting up spacing groove 5, can make sealing washer 4 remain in end cover 3 one side throughout, the dismouting of the shell 1 of being convenient for can effectively prevent the removal of sealing washer 4 when the dismouting to can reduce the man-hour of production and maintenance, can improve production and maintenance efficiency.
Specifically, as shown in fig. 2, when the casing 2 is detached from the end cover 3, the sealing ring 4 is not adhered to one side of the casing 2 or falls off, but is fixed at the position of the limiting groove 5 on one side of the end cover 3, so that the axle can be conveniently disassembled and assembled on the casing 1, the movement of the sealing ring 4 can be effectively prevented when the axle is disassembled and assembled, the labor hour for production and maintenance can be reduced, and the production and maintenance efficiency can be improved.
In addition, as shown in fig. 1, with respect to the housing 1 of the axle, the mounting opening 6 includes: inner opening portion 8 and outer opening portion 9, be formed with step 10 between inner opening portion 8 and the outer opening portion 9, collar 7 stretches into inner opening portion 8 and outer opening portion 9, and the periphery wall and the inner opening portion 8 cooperation of collar 7, sealing washer 4 seal in outer opening portion 9. Preferably, the seal ring 4 abuts on the step 10, so that the outer peripheral walls of the seal ring 4 and the mounting ring 7 can be tightly fitted on the inner opening portion 8 and the step 10, whereby a better sealing effect can be achieved. Like this, the shell 1 of installation axle can guarantee that casing 2 and end cover 3 can install as an organic whole to can guarantee that sealing washer 4 has good sealed to casing 2 interior part and lubricating oil.
In addition, as shown in fig. 2, for the housing 1 of the axle, the outer peripheral wall of the mounting ring 7 is further provided with an annular chamfer 11, and the annular chamfer 11 is located outside the stopper groove 5. The annular chamfer 11 may facilitate the mounting of the sealing ring 4 and may protect the sealing ring 4 from damage during mounting.
In addition, as shown in fig. 1, the inner diameter of the mounting opening 6 is larger than the outer diameter of the sealing ring 4, and the mounting opening 6 and the sealing ring 4 which are arranged in this way can ensure that the sealing ring 4 is smoothly mounted in the mounting opening 6 on one hand, and can avoid the phenomenon that the sealing ring 4 is damaged by trimming in the mounting process due to the overlarge outer diameter.
According to the utility model discloses a specific embodiment, sealing washer 4 can be the rubber circle, and the rubber circle is the elastomer, and it can stretch or compress, and sealing washer 4 can fix in spacing groove 5 department when 5 interference fit with spacing groove like this, can fill the space between step 10 and the end cover 3 that interior opening 8 and outer opening 9 formed, make 1 leakproofness of shell of axle better.
According to the utility model discloses axle, including the shell 1 of the axle of above-mentioned embodiment. The axle can be connected with the frame (or the bearing type vehicle body) through the suspension, wheels are arranged at two ends of the axle, and power is transmitted to the wheels through a half shaft in the axle. The axle is used for bearing the load of the automobile and maintaining the normal running of the automobile on the road.
According to the utility model discloses vehicle, including the axle of above-mentioned embodiment, this vehicle can refer to the vehicle with wheel pivoted on land.
