Abstract
Description
Technical Field
[0001] This utility model relates to the field of drive axles, and in particular to a waterproof drive axle with large turning angle. Background Technology
[0002] The drive axle is a mechanism located at the end of the transmission system that changes the speed and torque from the transmission and transmits them to the drive wheels. A drive axle typically consists of a final drive, differential, gear drive, and drive axle housing; steering drive axles also include a constant velocity joint.
[0003] Since the drive axle is installed at the bottom of the car and is usually partially exposed, it is easily affected by stones and sewage splashed on the road when the car is driving.
[0004] Therefore, it is necessary to propose a large-angle waterproof drive axle to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a large-angle waterproof drive axle to solve the problem that, since the drive axle is installed at the bottom of the car and a part of it is usually exposed, stones and sewage splashed on the road can easily affect the drive axle when the car is driving.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a large-angle waterproof drive axle, including a drive axle housing, bushings on both sides of the drive axle housing, one end of each bushing communicating with the interior of the drive axle housing, a connecting seat fixed at the bottom of each bushing, a fixing block connected to the bottom of each connecting seat, a rotating shaft rotatably connected to both sides of the fixing block, a baffle fixed at the opposite end of each rotating shaft, a pointed tip on both sides of the baffle, and a torsion spring on the outer side of each rotating shaft;
[0007] A half-shaft is rotatably connected inside the bushing, and an injection port is connected to the top of the bushing, which communicates with the inside of the bushing.
[0008] Preferably, the baffles are distributed parallel to each other along the length of the corresponding bushing, and a gap is left between the top of the baffle and the lower surface of the corresponding bushing.
[0009] Preferably, an oil-absorbing cloth is fixedly connected to the inner wall of the bushing, the oil-absorbing cloth is spirally distributed along the length of the bushing, and the inner side of the oil-absorbing cloth and the outer side of the corresponding half shaft are in contact with each other.
[0010] Preferably, the width of the baffle is greater than the width of the corresponding bushing.
[0011] Preferably, the connecting seat is triangular, and the top of the connecting seat has an arc groove that matches the arc surface of the corresponding bushing. The lower surface of the bushing is engaged in the corresponding arc groove, and the connecting area is welded.
[0012] Preferably, a flexible column is fixed between the lower surface of the bushing and the middle of the top of the corresponding baffle. Multiple flexible columns are provided, and the multiple flexible columns are evenly distributed along the length direction of the baffle, and all of the multiple flexible columns are elastic.
[0013] The technical effects and advantages of this utility model are as follows:
[0014] 1. In the actual operation of this utility model, the baffle can cover the bottom end of the bushing. During the driving process, it can block stones or sewage splashed on the road surface, prevent stones and sewage from damaging the drive axle, and play a protective role. At the same time, during the driving process, wind can pass through the upper and lower surfaces of the baffle, which can cut the wind force and reduce resistance.
[0015] 2. Furthermore, when the wind passes unevenly over the upper and lower surfaces of the baffle, the wind balance is disrupted, causing the baffle to rotate and tilt. This causes one end of the baffle to adhere to the lower surface of the bushing. Since the baffle is tilted, if there is residual rainwater and impurities at the bottom of the baffle, they can automatically slide down due to the tilt angle and their own weight, thus completing the cleaning function.
[0016] 3. In the actual operation of this utility model, lubricating oil can be injected into the inside of the bushing through the injection port. The oil cloth can absorb the lubricating oil. Since the oil cloth is distributed in a spiral shape, when the half shaft rotates, the lubricating oil on the oil cloth can be evenly applied to the half shaft through friction. At the same time, the oil cloth can absorb excess lubricating oil. Attached Figure Description

[0021] This utility model provides, for example Figures 1-3The large-angle waterproof drive axle shown includes a drive axle housing 1. Both sides of the drive axle housing 1 are provided with bushings 2. The opposite ends of the two bushings 2 are connected to the interior of the drive axle housing 1. A connecting seat 4 is fixed to the bottom of each of the two bushings 2. A fixing block 5 is connected to the bottom of each of the two connecting seats 4. Rotating shafts 6 are rotatably connected to both sides of the fixing block 5. A baffle 7 is fixed to the opposite ends of each of the two rotating shafts 6. Points 8 are provided on both sides of the baffle 7. Torsion springs are provided on the outer sides of each of the two rotating shafts 6. The width of the baffle 7 is greater than the width of the corresponding bushing 2.
[0022] In the actual operation of this utility model, the baffle 7 can block the bottom end of the bushing 2. During the driving process, it can block stones or sewage splashed on the road surface, prevent stones and sewage from damaging the drive axle, and play a protective role. At the same time, during the driving process, wind can pass through the upper and lower surfaces of the baffle 7, which can cut the wind force and reduce resistance.
[0023] Furthermore, when the wind passes unevenly over the upper and lower surfaces of the baffle 7, the wind balance is disrupted, causing the baffle 7 to rotate and tilt. This causes one end of the baffle 7 to adhere to the lower surface of the bushing 2. Since the baffle 7 is tilted, if there is residual rainwater and impurities at the bottom of the baffle 7, they can automatically slide down due to the tilt angle and their own weight, thus completing the cleaning function.
[0024] The rotation angle of the baffle 7 can be adjusted by controlling the height between the baffle 7 and the bushing 2. The higher the height, the greater the rotation angle of the baffle 7. This can be adjusted according to actual needs.
[0025] When the car stops and the wind force is lost, the torsion spring can reset the baffle 7 and make it parallel to the bushing 2.
[0026] A flexible column 11 is fixed between the lower surface of the bushing 2 and the middle of the top of the corresponding baffle 7. Multiple flexible columns 11 are provided, and the multiple flexible columns 11 are evenly distributed along the length direction of the baffle 7, and all of the multiple flexible columns 11 are elastic.
[0027] Multiple flexible columns 11 can enhance the connection strength between the baffle 7 and the corresponding bushing 7, so that the baffle 7 can still maintain stability under the action of wind. At the same time, since the flexible columns 11 are elastic, when the baffle 7 rotates and tilts, it will squeeze the flexible columns 11, thus not affecting the rotation of the baffle 7.
[0028] A half-shaft 9 is rotatably connected inside the bushing 2, and an injection port 3 is connected to the top of the bushing 2, which is connected to the inside of the bushing 2.
[0029] The baffles 7 are distributed parallel to the length of the corresponding bushing 2, and there is a gap between the top of the baffle 7 and the lower surface of the corresponding bushing 2.
[0030] An oil-absorbing cloth 10 is fixedly connected to the inner wall of the bushing 2. The oil-absorbing cloth 10 is spirally distributed along the length of the bushing 2, and the inner side of the oil-absorbing cloth 10 and the outer side of the corresponding half shaft 9 are in contact with each other. The connecting seat 4 is set as a triangle, and the top of the connecting seat 4 is provided with an arc groove that matches the arc surface of the corresponding bushing 2. The lower surface of the bushing 2 is engaged in the corresponding arc groove, and the connection area is welded.
[0031] In the actual operation of this utility model, lubricating oil can be injected into the inside of the bushing 2 through the injection port 3. The oil cloth 10 can absorb the lubricating oil. Since the oil cloth 10 is spirally distributed, when the half shaft 9 rotates, the lubricating oil on the oil cloth 10 can be evenly applied to the half shaft 9 through friction. At the same time, the oil cloth 10 can absorb excess lubricating oil.
