Detailed Implementation
[0026] According to one embodiment of the present invention, a hybrid camping trailer 100 (i.e., a towable accommodation) is provided, which is towed by a vehicle such as a four-wheel drive (4WD) vehicle. The hybrid camping trailer 100 has four rigid sides 102 extending upward from a chassis 104, and a pop-out canopy 106 extending upward from the sides 102. The chassis 104 terminates at a tongue-shaped coupler 108 for coupling to the 4WD tow ball. The hybrid camping trailer 100 also includes a pair of independent wheel stabilizer units 110 for mounting on opposite sides of the trailer chassis 104.
[0027] from Figure 2 As can be clearly seen, each lateral wheel stabilizer device 110 includes a stabilizer 200 for stabilizing the orientation of the wheel 202 as the wheel 202 moves relative to the chassis 104 through a vertical stroke. Figure 2 The solid lines in the figure show the default wheel configuration of the camping trailer 100 when stationary, while the dashed lines show the wheel configuration with the left side raised or the right side lowered when towing on rough terrain. Advantageously, as shown, when towing the camping trailer 100 on rough terrain and through bushes, the stabilizer 200 can keep the wheels 202 in a substantially vertical orientation, where grooves left by the wheels are inevitable on the tracks.
[0028] from Figure 3 As can be clearly seen, each wheel stabilizer assembly 110 includes a main side arm 300 for pivotally fastening about the front sleeve 302 to and along the side of the chassis 104. The wheel stabilizer assembly 110 also includes a steering knuckle support 304 for mounting to the rear end of the side arm 300. Furthermore, the stabilizer assembly 110 includes a hub assembly 306 for rotatably mounting the wheel 202 to the steering knuckle support 304. When the side arm 300 pivots relative to the chassis 104, the stabilizer 200 stabilizes the wheel 202 in a substantially vertical orientation.
[0029] The stabilizer 200 includes a top control arm 308A and a bottom control arm 308B, which allows the rear ends of the side wings 300, and thus the wheels 202, to move vertically. The control arms 308A and 308B are secured to the chassis 104 and the rear ends of the main side wings 300, and extend between the chassis 104 and the rear ends of the main side wings 300. The stabilizer 200 also includes a central toe-in stabilizer arm 310 located between the control arms 308A and 308B, secured to the chassis 104 and the steering knuckle support 304, and extending between the chassis 104 and the steering knuckle support 304.
[0030] Control arms 308A, 308B and toe-stabilizing arm 310 are located behind the rotation axle of wheel 202, facing the rear of camping trailer 100. Toe-stabilizing arm 310 extends outward to steering knuckle support 304, beyond control arms 308A, 308B. The rear of wing arm 300 includes arm mounting bracket 312 for receiving control arms 308A, 308B. Conversely, steering knuckle support 304 receives toe-stabilizing arm 310 within cavity 314.
[0031] The control arms 308A, 308B and the toe stabilizer arm 310 are pivotally mounted to their respective ends using elastic rubber bushings 316, through which fastening bolts pass. Similarly, the front sleeve 302 of the main side wing arm 300 and the top and bottom sleeves 318A, 318B of the steering knuckle support 304 also receive elastic bushings 316 for resilient pivot mounting.
[0032] The stabilizer 200 also includes a two-stage adjuster 320 for adjusting the orientation of the wheels 202 during wheel alignment. The adjuster 320 adjusts the length of the top control arm 308A and the toe-in stabilizer arm 310 of the stabilizer 200. The length of the bottom control arm 308B is fixed. Each adjustable arm 308A, 310 includes a central threaded nut lock 322 for locking the arm 308A, 310 to the desired length.
[0033] The main side arm 300 includes an airbag support 324 from which an airbag extends, and a shock absorber support 326 for mounting a shock absorber. The steering knuckle support 304 includes a caliper support 328 for mounting a brake caliper.
[0034] from Figure 4 As can be clearly seen, each wheel stabilizer unit 110 includes a suspension 400. The suspension 400 includes an airbag 402 mounted between the airbag mount 324 of the main side arm 300 and the chassis 104. The suspension 400 also includes a gas shock absorber 404 mounted between the shock absorber bracket 326 of the main side arm 300 and the chassis 104. The components 200, 300, 402, and 404 can be mounted to the chassis 104 using appropriate brackets.
[0035] The wheel stabilizer assembly 110 includes a brake assembly 406. The brake assembly 406 includes a rotating brake disc 408. The brake assembly 406 also includes a caliper 410, which is mounted to a caliper mount 328 of the steering knuckle support 304 for engaging with the brake disc 408.
[0036] The wheel hub assembly 306 includes a rotating hub 412 with a protruding threaded shaft to which the wheel 202 is fastened. The wheel hub assembly 306 also includes a base for mounting to a steering knuckle support 304, and a bearing located between the base and the hub 412 to allow the hub 412 to rotate relative to the steering knuckle support 304.
[0037] Figure 5B and Figure 6B The rear view showcases the features of the stabilizer 200, and the default wheel configuration when the camping trailer 100 is stationary (e.g., ...). Figure 5B (as shown) to the lowered wheel configuration used when towing on rough terrain (such as) Figure 6B (As shown). The stabilizer 200 ensures that the wheel 202, which is positioned parallel to the brake disc 408, remains substantially vertical throughout the suspension travel. The parallel control arm 308 and the toe-in stabilizer arm 310 limit the movement of the wheel 202 in its vertical orientation and prevent its rotation.
[0038] Figure 5A and Figure 6A From above, it is confirmed once again that wheel 202, which is positioned parallel to brake disc 408, remains essentially perpendicular. Toe angle refers to... Figure 5A and Figure 6A When viewed from above, the stabilizer 200 keeps the toe angle at zero degrees. The toe stabilizer arm 310 keeps the wheel 202 straight throughout the entire travel of the suspension 400. The geometry of the upper control arm 308 (camber link) provides camber angle variation at various points in the suspension travel, thereby producing motion that helps the trailer 100 achieve more desirable handling characteristics.
[0039] Figure 7 The hybrid camping trailer 100 shown may include two pairs of wheel stabilizer devices 110.
[0040] According to another embodiment of the present invention, a wheel stabilizer device is provided, such as... Figure 8 As shown. The same reference numerals denote the same features as described above.
[0041] The wheel stabilizer assembly 110 includes a side arm 300 for movably securing to the side of the chassis 104. The wheel stabilizer assembly 110 also includes a steering knuckle support 304 for mounting to the side arm 300, to which the wheel 202 is rotatably mounted. The wheel stabilizer assembly 110 also includes a stabilizer 200 for stabilizing the orientation of the wheel 202 as it moves relative to the chassis 104 through its vertical travel.
[0042] The stabilizer 200 includes an upper control arm 308A and a lower control arm 308B extending between a chassis 104 and a steering knuckle support 304. The stabilizer 200 also includes a toe-in stabilizer arm 310 extending between the chassis 104 and the steering knuckle support 304. The toe-in stabilizer arm 310 is located behind the control arms 308A and 308B and includes an airbag housing 324 from which an airbag 402 extends.
[0043] The airbag 402 is no longer mounted on the tow arm 300. It is now mounted on the toe stabilizer arm 310. In the first embodiment, the airbag 402 was located on the tow arm 300, and the control arm 308 experienced lateral loads due to the inward rotational load applied by the airbag 402. This caused wear on the bushing 316 and required constant adjustment of the screw thread 322 for alignment.
[0044] In this embodiment, the airbag 402 is mounted on the stabilizer arm 310, which significantly reduces these loads and allows for a simpler adjustment method, while improving the lifespan, strength, weight, and simplicity of all components of the suspension system.
[0045] Steering knuckle support 304 is fastened to control arms 308A, 308B, toe-in stabilizer arm 310, and wing arm 300. Stabilizer 200 includes stabilizer bar 800 for coupling to control arms 308A, 308B (see also...). Figure 9 Located on both sides of camping trailer 100, from Figure 10 This can be clearly seen in the text.
[0046] See Figure 11 The stabilizer 200 includes an adjustment cam device 1100 for adjusting the control arm 308 to the desired length. Therefore, adjustment is no longer required via a screw thread with a locking nut 322 at the center of the arms 308, 310. Adjustment is now achieved via camber adjustment bolts on the chassis side of the upper control arm 308A and lower control arm 308B. These bolts utilize offset cams, allowing the arms 308 to move in and out by rotating the bolt heads, and are locked in place by the nuts.
[0047] Figure 12The installation of the wheel stabilizer device 110 on the chassis 104 is shown. This invention is particularly applicable to any form of towable accommodation facility, whether it is a camping trailer, caravan, or hybrid unit.
[0048] refer to Figure 13A and Figure 13B Each wheel stabilizer unit 110 includes an electric motor 1800 for driving the wheel 202. Advantageously, each onboard motor 1800 can drive its wheel 202 during recovery from a 4WD towing camping trailer 100 stuck in mud. Each motor 1800 can be controlled independently to improve maneuverability when parked, facilitating steering of the camping trailer 100, which relies on front idler casters, when unhooked from the 4WD.
[0049] The camping trailer 100 includes a remote control that controls each motor 1800 to be driven in both forward and reverse directions.
[0050] The motor 1800 extends through the steering knuckle support 304 and engages with the wheel hub assembly 306. The motor 1800 includes a rotating shaft 1802 and a body 1804, with the shaft 1802 extending from the body 1804. The shaft 1802 is coupled to the rotating hub 412 of the wheel hub assembly 306 via a splined arrangement. The body 1804 is fixed to the steering knuckle support 304 and / or the main side arm 300 of the wheel stabilizer assembly 110.
