The impact of bumping on the brake shaft is effectively reduced, the brake shaft cannot be bent, due to the arrangement of the sealing gasket, air in the sleeve shaft can only be sucked in or discharged out through the air holes, the damping and buffering functions are achieved, and the service life of the brake shaft is prolonged.

Description

Technical Field

[0001] The utility model relates to the field of brake shaft structures, in particular to a brake shaft structure for parking. Background Art

[0002] The general principle of braking is to fix a wheel or disc on the high-speed shaft of the machine, install the corresponding brake shoe, belt or disc on the machine base, and generate braking torque under the action of external force. The parking brake shaft is installed in the vehicle gearbox and connected to the shaft of the brake component. Generally, one end is connected to the parking brake and the other end is connected to the motor shaft.

[0003] However, most of the brake shaft structures in the existing market are integrated structures. During use, the car will be bumpy when driving, and long-term bumps will easily cause the brake shaft to wear quickly, thereby reducing the braking effect.

[0004] Therefore, it is necessary to provide a parking brake shaft structure to solve the above technical problems. Utility Model Content

[0005] The utility model provides a parking brake shaft structure, which solves the problem that the brake shaft structure in the existing market is not convenient for loading and processing during use, requires manual handling for shearing, resulting in reduced work efficiency, and is not convenient for correcting the position of the plate, causing the plate to easily tilt during shearing and inconvenient for unloading.

[0006] The utility model provides a parking brake shaft structure, comprising: a sleeve shaft, the interior of the sleeve shaft is provided with first positioning grooves in an equidistant annular shape, and the number of the first positioning grooves is multiple, first positioning blocks are slidably installed inside the multiple first positioning grooves, a sliding shaft is fixedly installed between the multiple first positioning blocks, a sealing gasket is fixedly installed at one end of the sliding shaft, an air hole is provided on the exterior of the sleeve shaft, and the number of the air holes is two, and the sliding shaft is slidably installed with the sleeve shaft along the length direction of the first positioning groove through the cooperation between the first positioning block and the first positioning groove.

[0007] Preferably, one end of the sleeve shaft and the other end of the sliding shaft are both fixedly mounted with a sleeve, and a connecting shaft is slidably mounted inside the sleeve.

[0008] Preferably, the inner wall of the sleeve is provided with second positioning grooves in an equidistant annular shape, and there are multiple second positioning grooves, and second positioning blocks are slidably installed inside the multiple second positioning grooves, and the multiple second positioning blocks are fixedly installed with the connecting shaft.

[0009] Preferably, a fixing sleeve is fixedly installed in an equidistant annular manner on the outside of the sleeve, and there are multiple fixing sleeves, and a pin is slidably installed inside the fixing sleeve.

[0010] Preferably, one end of the pin passes through the fixing sleeve and is fixedly mounted with a handle, a limiting ring is fixedly mounted outside the pin and inside the fixing sleeve, and a spring is sleeved outside the pin and on one side of the limiting ring.

[0011] Preferably, positioning holes are equidistantly provided in an annular shape on the outside of one end of the connecting shaft, and there are multiple positioning holes, which are matched with the inserting pins.

[0012] Compared with the related art, the parking brake shaft structure provided by the utility model has the following beneficial effects:

[0013] The car will bump during driving, and long-term bumps can easily cause rapid wear of the brake shaft, thereby reducing the braking effect. When bumps occur, the sliding shaft slides inside the sleeve shaft, thereby changing the size of the entire brake shaft, effectively reducing the impact of the bumps on the brake shaft, so that the brake shaft will not bend. Due to the setting of the sealing gasket, the air inside the sleeve shaft can only be inhaled or discharged through the air holes, thereby having damping and buffering functions, and extending the service life of the brake shaft.

[0020] A sleeve 7 is fixedly installed on one end of the sleeve shaft 1 and the other end of the sliding shaft 4, and a connecting shaft 8 is slidably installed inside the sleeve 7. The inner wall of the sleeve 7 is provided with second positioning grooves 9 in an equidistant ring shape, and there are multiple second positioning grooves 9. Second positioning blocks 10 are slidably installed inside the multiple second positioning grooves 9. The multiple second positioning blocks 10 and the connecting shaft 8 are fixedly installed. The cooperation between the second positioning blocks 10 and the second positioning grooves 9 facilitates the positioning and installation of the sleeve 7 and the connecting shaft 8.

[0021] The outer ring of the sleeve 7 is equidistantly fixed with a fixing sleeve 11, and the number of the fixing sleeves 11 is multiple. The inner part of the fixing sleeve 11 is slidably installed with a pin 12, one end of the pin 12 passes through the fixing sleeve 11 and is fixedly installed with a handle 13. The outer part of the pin 12 and the inner part of the fixing sleeve 11 are fixedly installed with a limit ring 14, and the outer part of the pin 12 and the one side of the limit ring 14 are sleeved with a spring 15.

The structure is simple and convenient for installing or disassembling both ends of the brake shaft.

[0022] The working principle of a parking brake shaft structure provided by the utility model is as follows:

[0023] Step 1: The car will bump during driving, and long-term bumps will easily cause the brake shaft to wear quickly, thereby reducing the braking effect. When bumps occur, the sliding shaft 4 slides inside the sleeve shaft 1, thereby changing the size of the entire brake shaft, effectively reducing the impact of the bumps on the brake shaft, so that the brake shaft will not bend. Due to the setting of the sealing gasket 5, the air inside the sleeve shaft 1 can only be inhaled or discharged through the air hole 6, thereby having damping and buffering functions, thereby extending the service life of the brake shaft.

[0024] Step 2: Through the cooperation between the second positioning block 10 and the second positioning groove 9, it is convenient to position and install the sleeve 7 and the connecting shaft 8. Insert the connecting shaft 8 into the interior of the sleeve 7, and pull the pin 12 outward through the handle 13. At this time, the spring 15 is compressed. After the pin 12 enters the interior of the fixing sleeve 11, continue to insert the connecting shaft 8 into the innermost part of the sleeve 7, and slowly loosen the handle 13. Due to the reset effect of the spring 15, the pin 12 moves, and the pin 12 is inserted into the interior of the connecting shaft 8 through the positioning hole 16. The structure is simple and convenient for installing or disassembling both ends of the brake shaft.

[0025] Compared with the related art, the parking brake shaft structure provided by the utility model has the following beneficial effects:

[0026] The vehicle may bump during driving, and long-term bumping can easily cause rapid wear of the brake shaft, thereby reducing the braking effect. When bumps occur, the sliding shaft 4 slides inside the sleeve shaft 1, thereby changing the size of the entire brake shaft, effectively reducing the impact of the bumps on the brake shaft, so that the brake shaft will not bend. Due to the setting of the sealing gasket 5, the air inside the sleeve shaft 1 can only be inhaled or discharged through the air hole 6, thereby having damping and buffering functions, thereby extending the service life of the brake shaft.
