Description

Technical Field

[0001] The present invention belongs to the technical field of hydraulically controlled clutch motors, and in particular relates to hydraulically controlled clutch motors. Background Art

[0002] The working principle of a motor is that the energized coil rotates in a magnetic field, driving the starter rotor to rotate, and the small gear on the rotor drives the engine flywheel to rotate.

[0003] For related technologies, reference may be made to the Chinese invention patent with authorization announcement number CN204733022U, which discloses a clutch motor comprising: a bracket, which forms a space with a case cover to accommodate components of the clutch motor; a motor, which is fixed to one side of the bracket, and has a worm at one end thereof extending into the bracket, which can transmit the kinetic energy generated by the motor to the inside of the bracket; a worm gear set, which is arranged inside the bracket and is meshed with the worm of the motor; a sensor, which is fixed to the top of the inner side of the bracket and can detect the number of rotations and position of the worm gear set; and a transmission gear, which is installed at one end of the transmission core shaft of the worm gear set that passes through the outside of the case cover and is linked to it.

[0004] The inventor believes that the above existing technical solutions have the following technical problems: the turbine group and the worm gear of the motor are engaged and rotated. After long-term use, the teeth on the turbine group and the teeth on the gear are prone to wear, thereby affecting the service life of the motor. Summary of the Invention

[0005] The object of the present invention is to provide a hydraulically controlled clutch motor in order to solve the above problems.

[0006] The present invention achieves the above-mentioned purpose through the following technical solutions:

[0007] A hydraulically controlled clutch motor comprises a housing and a motor mounting base, wherein the housing and the motor mounting base are connected and fixed by bolts, a cycloid motor is mounted on the motor mounting base, an end cover is fixedly connected to the housing by bolts, a movable tooth is splined to the rotating shaft of the cycloid motor, a first end face tooth is provided on the movable tooth, a piston is provided in the housing, the piston is slidably connected to the inner shell wall of the housing, the movable tooth is rotatably connected to the piston via a deep groove ball bearing, an output shaft is rotatably connected to the end cover via the deep groove ball bearing, a second end face tooth is provided on the output shaft that meshes with the first end face tooth, and a sprocket is fixedly connected to the output shaft by bolts;

[0008] The housing is also provided with a pushing assembly for pushing the piston to move;

[0009] The housing is also provided with a lubrication mechanism for providing lubrication to the movable teeth and the output shaft.

[0010] By adopting the above technical solution, in order to reduce the damage caused by impact when the movable tooth contacts the output shaft, the lubrication mechanism is used to spray lubricating oil on the second end face tooth of the output shaft when the movable tooth contacts the output shaft, thereby facilitating the engagement of the end face tooth on the movable tooth with the second end face tooth on the output shaft, thereby reducing the possibility of damage to the first end face tooth and the second end face tooth when the movable tooth contacts the output shaft;

[0011] When the sprocket needs to be driven to rotate, the push assembly is used to move the movable tooth toward the side close to the output shaft. After the first end face tooth is meshed with the second end face tooth, the cycloid motor is started to rotate the rotating shaft of the cycloid motor, thereby driving the output shaft to rotate. The rotation of the output shaft drives the sprocket to rotate.

[0012] When the drive sprocket does not need to be rotated, the pushing assembly is used to move the piston and the movable tooth to the side away from the output shaft. After the first end face tooth is separated from the second end face tooth, the movable tooth no longer acts on the output shaft, thereby not affecting the rotation of the chain.

[0013] As a further optimization solution of the present invention, the lubrication mechanism includes a fixing frame, a delivery pipe, a rubber head, a nozzle, a connecting pipe and a rubber plug, the fixing frame is fixedly connected to the inner wall of the shell, the delivery pipe is provided on the fixing frame, the nozzle is fixedly connected to the delivery pipe, a mounting groove is provided on the shell, the rubber head is fixedly connected to the delivery pipe, and the rubber head is located in the mounting groove, the connecting pipe is fixedly connected to the rubber head, and a liquid storage tank and a liquid inlet hole are provided on the shell, and the rubber plug abuts against the inner wall of the liquid inlet hole;

[0014] The lubricating mechanism further includes a trigger component for deforming the rubber head.

[0015] By adopting the above technical solution, the lubricating liquid is first injected into the liquid storage tank through the liquid inlet hole for storage, and then sealed with a rubber plug. Thereafter, the trigger assembly is used to compress the rubber head, so that the lubricating liquid is sprayed from the nozzle onto the second end face tooth on the output shaft. After the first end face tooth and the second end face tooth are in contact, the lubricating oil is used to facilitate the meshing of the first end face tooth and the second end face tooth, thereby improving the safety of the movable tooth and the output shaft after the first end face tooth and the second end face tooth are in contact.

[0016] As a further optimization scheme of the present invention, the trigger assembly includes a push rod, a movable plate and a trigger rod, the push rod is fixedly connected to the piston, the shell is provided with a communicating sliding groove and a sliding hole, the trigger rod is slidingly connected to the inner wall of the sliding hole, the trigger rod is in contact with the rubber head, the movable plate is fixedly connected to the trigger rod, and the movable plate can move along the direction of the sliding groove.

[0017] By adopting the above technical solution, when the piston moves toward the side close to the output shaft, it drives the push rod to move. After the push rod contacts the movable plate, it pushes the movable plate and the trigger rod to move. The movement of the trigger rod causes the rubber head to deform, thereby causing the lubricating liquid in the delivery pipe to be sprayed out.

[0018] As a further optimization scheme of the present invention, the pushing assembly includes an oil pump, an oil tank, a control element and a connecting pipe. The oil tank is arranged on one side of the shell. A hydraulic hole is opened on the shell. One end of the connecting pipe is fixedly connected to the inner wall of the hydraulic hole. The other end of the connecting pipe is fixedly connected to the oil pump. A control element is provided on the connecting pipe.

[0019] By adopting the above technical solution, when it is necessary to push the piston to move, the oil pump and the control element are started, so that the hydraulic oil flows into the housing through the hydraulic hole. After the hydraulic oil fills the housing, the piston can be pushed to move.

[0020] As a further optimization solution of the present invention, the control element includes a pressure valve, a flow valve and a directional valve, and the pressure valve, the flow valve and the directional valve are all installed on the connecting pipe.

[0021] By adopting the above technical solution, the direction, flow rate and flow velocity of the hydraulic oil are adjusted by using the pressure valve, flow valve and directional valve, so that the movement of the piston can be better controlled.

[0022] As a further optimization solution of the present invention, the shell includes a first shell and a second shell, the inner shell diameter of the first shell is larger than the inner shell diameter of the second shell, the piston is slidingly connected to the inner shell wall of the first shell, and the piston abuts against the second shell.

[0023] By adopting the above technical solution, the piston abuts against the side wall of the second shell, so that the piston is limited, thereby reducing the possibility of the piston continuing to move toward the side close to the output shaft, reducing the force when the movable tooth contacts the output shaft, and thus improving the safety of the movable tooth and the output shaft.

[0024] As a further optimization solution of the present invention, a clearance groove is provided on the piston.

[0025] By adopting the above technical solution, the hydraulic oil enters the clearance groove and fully contacts the piston, thereby facilitating the movement of the piston.

[0026] As a further optimization solution of the present invention, an O-ring is fixedly connected to both the first shell component and the second shell component, and a Gly ring is fixedly connected to the O-ring.

[0027] By adopting the above technical solution, the grid ring is closely attached to the piston surface, thereby reducing the possibility of hydraulic oil overflowing from the gap between the housing and the piston.

[0028] As a further optimization scheme of the present invention, a protection component is provided on the motor mounting seat, and the protection component includes a buffer pad, a buffer rod and a buffer spring. The motor mounting seat is provided with a connected sliding groove and a through hole, the buffer rod is arranged through the through hole, the buffer pad is provided with a convex groove, and the end of the buffer rod is located in the convex groove, the buffer pad is fixedly connected to the motor mounting seat, one end of the buffer spring is fixedly connected to the buffer rod, and the other end of the buffer spring is fixedly connected to the inner wall of the sliding groove.

[0029] By adopting the above technical solution, when the piston moves to the side away from the output shaft, after contacting the buffer pad, the buffer pad is deformed, and the buffer pad is used to absorb part of the energy generated by the impact between the piston and the motor mount. After the buffer pad is deformed, it pushes the buffer rod to move, causing the buffer spring to compress, so that it can continue to absorb part of the energy generated by the impact between the piston and the motor mount, thereby improving the stability of the structure.

[0030] As a further optimization solution of the present invention, an anti-falling block is fixedly connected to the buffer rod, and the anti-falling block is slidably connected to the inner wall of the sliding groove.

[0031] By adopting the above technical solution and utilizing the anti-falling block, the possibility of the buffer rod falling off from the motor mounting seat is reduced.

[0032] The beneficial effects of the present invention are as follows: in order to reduce the damage caused by the impact when the movable tooth contacts the output shaft, the lubricating mechanism is used to spray lubricating oil on the second end face teeth of the output shaft when the movable tooth contacts the output shaft, thereby facilitating the engagement of the end face teeth on the movable tooth with the second end face teeth on the output shaft, thereby reducing the possibility of damage to the first end face teeth and the second end face teeth when the movable tooth contacts the output shaft;

[0033] When the sprocket needs to be driven to rotate, the push assembly is used to move the movable tooth toward the side close to the output shaft. After the first end face tooth is meshed with the second end face tooth, the cycloid motor is started to rotate the rotating shaft of the cycloid motor, thereby driving the output shaft to rotate. The rotation of the output shaft drives the sprocket to rotate.

[0034] When the drive sprocket does not need to be rotated, the pushing assembly is used to move the piston and the movable tooth to the side away from the output shaft. After the first end face tooth is separated from the second end face tooth, the movable tooth no longer acts on the output shaft, thereby not affecting the rotation of the chain.

The movable tooth 23 is rotatably connected to the piston 24 through a deep groove ball bearing, and the end cover 22 is rotatably connected to the output shaft 25 through a deep groove ball bearing. The output shaft 25 is provided with a second end face tooth, and the first end face tooth is meshed with the second end face tooth. A sprocket is fixedly connected to the output shaft 25 by bolts. The housing 1 is also provided with a pushing component 3 for pushing the piston 24 to move. The housing 1 is also provided with a lubrication mechanism 4 for providing lubrication to the movable tooth 23 and the output shaft 25. The motor mounting seat 2 is provided with a protective component 6 for protecting the piston 24.

[0042] A clearance groove 241 is provided on the piston 24 , and the hydraulic oil enters the clearance groove 241 and fully contacts the piston 24 , thereby facilitating the movement of the piston 24 .

[0043] An O-ring 26 is fixedly connected to the first housing 1 and the second housing 1 , and a Gly ring 27 is fixedly connected to the O-ring 26 . The Gly ring 27 is tightly attached to the surface of the piston 24 , thereby reducing the possibility of hydraulic oil overflowing from the gap between the housing 1 and the piston 24 .

[0044] The pushing assembly 3 includes an oil pump 31, an oil tank 32, a control element 34 and a connecting pipe 33. The oil tank 32 is arranged on one side of the shell 1.

[0045] The control element 34 includes a pressure valve 35 , a flow valve 36 , and a directional valve 37 . The pressure valve 35 , the flow valve 36 , and the directional valve 37 are all installed on the connecting pipe 33 .

[0046] The lubrication mechanism 4 includes a fixing frame 41, a delivery pipe 42, a rubber head 43, a nozzle 44, a liquid inlet pipe 45, a rubber plug 46 and a trigger assembly 5. The fixing frame 41 is fixedly connected to the inner wall of the shell 1, the delivery pipe 42 is passed through the fixing frame 41, the nozzle 44 is fixedly connected to the delivery pipe 42, a mounting groove 14 is provided on the shell 1, the rubber head 43 is fixedly connected to the delivery pipe 42, and the rubber head 43 is located in the mounting groove 14, the liquid inlet pipe 45 is fixedly connected to the rubber head 43, and a liquid storage tank 15 and a liquid inlet hole 16 are connected on the shell 1, and the rubber plug 46 abuts against the inner wall of the liquid inlet hole 16.

[0047] The trigger assembly 5 includes a push rod 51, a movable plate 52 and a trigger rod 53. The push rod 51 is fixedly connected to the piston 24. The housing 1 is provided with a sliding groove 17 and a sliding hole 18 that are connected to each other. The trigger rod 53 slides along the inner wall of the sliding hole 18. The trigger rod 53 abuts against the rubber head 43. The movable plate 52 is fixedly connected to the trigger rod 53, and the movable plate 52 can move along the direction of the sliding groove 17.

[0048] In order to reduce the damage caused by impact when the movable tooth 23 contacts the output shaft 25, when the piston 24 moves to the side close to the output shaft 25, it drives the push rod 51 to move. After the push rod 51 contacts the movable plate 52, it pushes the movable plate 52 and the trigger rod 53 to move. The movement of the trigger rod 53 causes the rubber head 43 to deform, thereby allowing the lubricating fluid in the delivery pipe 42 to be sprayed out, and the sprayed lubricating oil is sprayed on the second end face tooth of the output shaft 25, thereby facilitating the engagement of the end face tooth on the movable tooth 23 with the second end face tooth on the output shaft 25, thereby reducing the possibility of damage to the first end face tooth and the second end face tooth when the movable tooth 23 contacts the output shaft 25.

[0049] A protective component 6 is provided on the motor mounting base 2, and the protective component 6 includes a buffer pad 61, a buffer rod 62 and a buffer spring 63. A connected sliding groove 28 and a through hole 29 are provided on the motor mounting base 2, and the buffer rod 62 is provided through the through hole 29. A convex groove 611 is provided on the buffer pad 61, and the end of the buffer rod 62 is located in the convex groove 611. An anti-falling block 64 is fixedly connected to the buffer rod 62, and the anti-falling block 64 slides on the inner wall of the sliding groove 28. The buffer pad 61 is fixedly connected to the motor mounting base 2, one end of the buffer spring 63 is fixedly connected to the buffer rod 62, and the other end of the buffer spring 63 is fixedly connected to the inner wall of the sliding groove 28.

[0050] When the piston 24 moves to the side away from the output shaft 25, after contacting the buffer pad 61, the buffer pad 61 is deformed, and the buffer pad 61 is used to absorb part of the energy generated by the collision between the piston 24 and the motor mount 2. After the buffer pad 61 is deformed, it pushes the buffer rod 62 to move, causing the buffer spring 63 to be compressed, so that it can continue to absorb part of the energy generated by the collision between the piston 24 and the motor mount 2, thereby improving the stability of the structure.

[0051] The working principle of the present invention is: in order to reduce the damage caused by impact when the movable tooth 23 contacts the output shaft 25, the lubricating mechanism 4 is used to spray lubricating oil on the second end face teeth of the output shaft 25, thereby facilitating the engagement of the end face teeth on the movable tooth 23 with the second end face teeth on the output shaft 25, thereby reducing the possibility of damage to the first end face teeth and the second end face teeth when the movable tooth 23 contacts the output shaft 25.

[0052] When it is necessary to drive the sprocket to rotate, the oil pump 31 is started, so that the hydraulic oil in the oil tank 32 flows into the connecting pipe 33, and then the pressure valve 35 and the flow valve 36 are started, so that the pressurized hydraulic oil enters the interior of the housing 1 through the hydraulic hole 13. After the hydraulic oil fills the interior of the housing 1, the piston 24 is pushed to move toward the side close to the output shaft 25. After the first end face teeth on the movable teeth 23 are meshed with the second end face teeth on the output shaft 25, the cycloid motor 21 is started, and the rotating shaft of the cycloid motor 21 rotates, thereby driving the movable teeth 23 to rotate. Since the first end face teeth are meshed with the second end face teeth, the rotation of the movable teeth 23 drives the output shaft 25 to rotate, and then the sprocket can be rotated;

[0053] When there is no need to drive the sprocket to rotate, in order not to affect the rotation of the sprocket, the oil pump 31, the pressure valve 35, the flow valve 36, and the directional valve 37 are started, so that the hydraulic oil in the housing 1 flows back to the oil tank 32, and a negative pressure is generated in the housing 1. Under the action of the negative pressure, the movable tooth 23 moves to the side away from the output shaft 25. Since the movable tooth 23 no longer affects the rotation of the output shaft 25 after it moves away from the output shaft 25, it will not affect the rotation of the sprocket.

[0054] The above-described embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that variations and improvements are possible without departing from the scope of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
