Example 1
Referring to fig. 1 and 2, there is provided a wheel 10 having a parking device in this embodiment, which includes a wheel axle 1, a wheel end cap 2 mounted on the wheel axle 1 and rotatable with the wheel 10 around the wheel axle 1, a rim 3 mounted on an edge portion of the wheel end cap, and a tire 4 mounted on the rim 3. The wheel end cover 2 is provided with a parking fluted disc 5. The wheel axle 1 is assembled with a fluted disc clamping mechanism 6 for limiting the rotation of the parking fluted disc 5 relative to the wheel axle 1. The wheel 10 is a conventional roller or powered hub motor wheel. This wheel 10 with parking device is through installing parking fluted disc 5 on wheel end cover 2, and parking fluted disc 5 can follow wheel end cover 2 and rotate around shaft 1, installs the fluted disc clamping mechanism 6 block in parking fluted disc 5 on shaft 1 when the vehicle is parked to the rotation of restriction parking fluted disc 5 relative shaft 1, and corresponding restriction wheel rotates, and the vehicle of installing this wheel 10 correspondingly realizes the parking function, controls conveniently.
Referring to fig. 2 and 3, the wheel 10 of the present embodiment includes a left wheel end cover 21 and a right wheel end cover 22. The left wheel end cap 21 and the right wheel end cap 22 are rotatably connected to the wheel axle 1 by bearings, respectively. The parking toothed disc 5 is mounted on the left wheel end cover 21 or the right wheel end cover 22. The rim 3 is mounted on the edge portions of the left and right wheel caps 21 and 22, and is located between the left and right wheel caps 21 and 22. The left wheel end cover 21, the rim 3 and the right wheel end cover 22 are fixedly connected by fasteners. A containing cavity is formed between the left wheel end cover 21 and the right wheel end cover 22. The parking fluted disc 5 and the fluted disc clamping mechanism 6 are assembled in the accommodating cavity, so that rainwater can be prevented from splashing into the fluted disc clamping mechanism 6, and the service life of the parking device is prolonged.
In this embodiment, the parking toothed disc 5 is an inner toothed disc. The inner gear disk is attached to the inner end surface of the left wheel end cover 21 and is fixedly connected with the left wheel end cover 21 through a fastener. The fastener is a screw. The inner fluted disc is annular and is arranged on the periphery of the wheel shaft 1 in a surrounding way. The tooth slot direction of the inner fluted disc is arranged radially relative to the wheel axle 1. When the left wheel end cover 21 rotates around the wheel axle 1, the inner toothed disc follows the left wheel end cover 21 to rotate around the wheel axle 1.
In this embodiment, a fixed base plate 7 for mounting a fluted disc clamping mechanism 6 is sleeved on the wheel shaft 1 of the wheel 10. The fixed base plate 7 is fixedly connected with the wheel axle 1. The fixed base plate 7 is assembled in the accommodating cavity of the wheel 10 and is positioned on one side of the wheel axle 1 where the left wheel end cover 21 is mounted, so that the mounting position of the fluted disc clamping mechanism 6 corresponds to the mounting position of the parking fluted disc 5. When the left wheel end cover 21 rotates around the wheel axle 1, the left wheel end cover 21 also rotates relative to the fluted disc holding mechanism 6 mounted on the fixed base plate 7.
Referring to fig. 4 and 5, the gear plate locking mechanism 6 includes a locking member 61 hinged to the fixed base plate 7, a torsion spring 62 connecting the locking member 61 and the fixed base plate 7, and a pushing mechanism 63 pushing the locking member 61 to be locked to the parking gear plate 5. The pushing mechanism 63 pushes the catch 61 in the circumferential direction of the wheel shaft 1, and the catch 61 is engaged with or disengaged from the tooth grooves of the internal gear disk in the direction perpendicular to the wheel shaft axis. When the wheel 10 stops rotating, the pushing mechanism 63 pushes the clamping piece 61 to be buckled on the tooth groove of the inner tooth disc, so that the rotation of the inner tooth disc relative to the wheel shaft 1 is limited, and the parking function of the vehicle can be realized.
The catch 61 includes a hinge end 611 hinged to the fixed base plate 7 and a pressing end 612 swinging following the hinge end 611. The hinge end 611 is hinged to the fixed base plate 7 by a pin. The torsion spring 62 includes a spring 621 sleeved on the pin shaft, and a first torsion arm 622 and a second torsion arm 623 respectively extending at both ends of the spring 621. The first torsion arm 622 is mounted on the fixed base plate 7, and the second torsion arm 623 abuts against the pressing end 612. The hinge end 611 of the catch 61 is provided with a U-shaped groove accommodating the spring 621, and the spring 621 is mounted in the U-shaped groove to reduce the mounting space of the torsion spring 62. The fixed base plate 7 is provided with a fixed block 71 which is held against the first torsion arm 622 to increase the stress reliability of the torsion spring 62. When the pushing mechanism 63 abuts against the pressing end 612 and pushes the pressing end 612 to buckle on the parking fluted disc 5 (as shown in fig. 6), the clamping piece 61 swings relative to the fixed substrate 7, the pressing end 612 buckles on the tooth slot to limit the rotation of the parking fluted disc 5 relative to the wheel shaft 1, and at this time, the second torsion arm 623 of the torsion spring 62 deforms and stores bending stress; when the pushing mechanism 63 releases the pushing force to the pressing end 612 (as shown in fig. 7), the torsion spring 62 returns the second torsion arm 623 from the deformed state to the initial position state by the stored bending stress, and drives the clamping member 61 to swing reversely relative to the fixed substrate 7, and the pressing end 612 is separated from the tooth slot of the parking fluted disc 5, so as to release the restriction of the clamping member 61 to the parking fluted disc 5, and at this time, the wheel can rotate freely.
The pressing end 612 of the clamping piece 61 is provided with a parking clamping body 613 for being clamped on the parking fluted disc 5 and a pressing block 614 opposite to the parking clamping body 613. The parking clamp body 613 is arranged opposite to the parking fluted disc 5 and is provided with sharp tooth grooves matched with the sharp tooth grooves, so that the sharp tooth grooves can be well clamped at any position of the sharp tooth grooves when the parking fluted disc 5 stops rotating relative to the wheel shaft 1, and the clamping performance of the clamping piece 61 and the parking fluted disc 5 is improved. The pushing mechanism 63 abuts against the pressing block 614 of the pressing end 612 and pushes the parking clamp body 613 to be buckled on the parking fluted disc 5. The operation is convenient.
In the present embodiment, the pushing mechanism 63 includes a telescopic device 631 mounted on the fixed base plate 7, and a pushing block 632 hinged to a pushing end of the telescopic device 631 and swinging around the wheel shaft 1. The push block 632 is rotatably connected to the wheel axle 1 by means of bearings. The push block 632 is rotated around the wheel shaft 1 by the pushing of the telescopic device 631. The pushing end of the telescopic device 631 is hinged to the middle of the pushing block 632. The top of the pushing block 632 abuts against the pressing block 614 of the clamping piece 61. The telescopic device 631, the pushing block 632 and the wheel axle 1 form a link mechanism, and the top of the pushing block 632 can push the clamping piece 61 through the smaller pushing force of the telescopic device 631. The pressing block 614 of the clamping piece 61 is provided with a first arc sliding surface 615, the top of the pushing block 632 is provided with a second arc sliding surface 633 which is pressed against the first arc sliding surface 615, and the sliding stability during pushing is improved through the relative sliding of the two arc sliding surfaces. Wherein: when the parking clamping body 613 of the clamping piece 61 is clamped on the tooth slot of the parking fluted disc 5, the reverse acting force of the parking fluted disc 5 relative to the parking clamping body 613 acts on the axle center position of the wheel axle 1, so that the parking reliability is improved. Of course, in other embodiments, the pushing block 632 of the pushing mechanism 63 may also swing around other hinge points mounted on the fixed base plate 7.

One end of the telescopic rod 83 is located inside the tubular housing 81 and connected to the compression spring 84, and the other end of the telescopic rod 83 is located outside the tubular housing 81 and hinged to the push block 632. When the electromagnetic switch is electrified, the electromagnetic coil 82 generates electromagnetic attraction force to pull the telescopic rod 83 inwards, the telescopic rod 83 drives the pushing block 632 to move towards the inner direction of the tubular shell 81, meanwhile, the compression spring 84 is in a compressed state, the pushing block 632 releases the pushing force on the clamping piece 61, the second torsion arm 623 of the torsion spring 62 drives the clamping piece 61 to swing reversely relative to the fixed substrate 7, the parking clamping body 613 of the clamping piece 61 is separated from a tooth slot (as shown in fig. 7) of the parking fluted disc 5, and the wheels are free to rotate; when the electromagnetic switch is powered off, the magnetic field of the electromagnetic coil 82 is released, the compression spring 84 in a compressed state is released, the compression spring 84 pushes the telescopic rod 83 to move towards the outside of the shell through the stretching force, the telescopic rod 83 drives the pushing block 632 to move towards the outside direction of the tubular shell 81, the pushing block 632 pushes the parking clamping body 613 of the clamping piece 61 and overcomes the bending stress of the torsion spring 62, the clamping piece 61 swings relative to the fixed substrate 7, the torsion spring 62 deforms, the pushing block 632 pushes the parking clamping body 613 to be buckled on a tooth slot (shown in fig. 6) of the parking fluted disc 5, the parking fluted disc 5 is limited to rotate relative to the wheel axle 1, and the parking function of the vehicle is achieved. Of course, in other embodiments, the telescopic device 631 may be an electric push rod or an air cylinder.
