Description

Technical Field

[0001] This invention relates to a parking system for a sidecar motorcycle, and more particularly to an independent mechanical parking system for a sidecar motorcycle. Background Technology

[0002] With social and economic development, motorcycles now serve more than just transportation; they also offer recreational benefits. Developing three-wheeled motorcycles, building upon the foundation of two-wheeled motorcycles, is both an advantage and a challenge for traditional motorcycle manufacturers. Compared to traditional two-wheeled motorcycles, sidecar motorcycles require additional parking brakes. While sidecar motorcycles are inherently stable, many on the market lack parking brake functionality. Some, though possessing it, typically use an automatic limit mechanism on the brake lever, relying on the existing braking system. Recent EU regulations require sidecar motorcycles to have independent mechanical parking systems, prohibiting them from sharing components like brake levers, brake lines, and brake calipers with the main braking system. Therefore, the development of new independent mechanical parking structures for sidecar motorcycles is urgently needed. Summary of the Invention

[0003] Purpose of the invention: The purpose of this invention is to provide an independent mechanical parking system for sidecar motorcycles, enabling sidecar motorcycles to park on slopes. It is simple and convenient to assemble, low in cost, and highly versatile.

[0004] Technical solution: The independent mechanical parking system for sidecar motorcycles of the present invention includes a parking handle, a parking handle limiting mechanism, a parking handle mounting bracket, a parking caliper, a parking caliper mounting plate, and a parking cable; wherein, the parking handle is fixed to the parking handle mounting bracket by bolts through the parking handle limiting mechanism, the parking cable is fixed to the parking handle mounting bracket by bolts, one end of the parking cable is mounted on the parking handle, and the other end is mounted on the rocker arm of the parking caliper, the parking caliper is clamped on the brake disc and fixed to the parking caliper mounting plate by bolts, and the parking caliper mounting plate is fixed to the front shock absorber together with the brake caliper of the braking system by bolts.

[0005] The parking caliper includes a parking caliper body, a camshaft assembly, a parking caliper rocker arm, a rocker arm washer, a spacer, a lock nut, a torsion spring, a spring pin, a return spring, an outer brake pad, and an inner brake pad. The camshaft assembly is bolted to the outer side of the parking caliper body along with the parking caliper rocker arm, rocker arm washer, and lock nut. The spring pin passes through the mounting holes of the outer and inner brake pads and the return spring between the mounting holes to fix the outer and inner brake pads in the groove inside the parking caliper body. A spacer (equivalent to the function of a brake disc, removed during vehicle assembly) is provided between the outer and inner brake pads to prevent the brake pads from contacting each other when not in use.

[0006] The parking handle limiting mechanism includes a limiting pressure plate, a limiting post resetting mechanism, a limiting plate fixing screw, a positioning bushing, a torsion spring, and mounting screws. The limiting pressure plate is fixed to the limiting post resetting mechanism together with the positioning bushing and the torsion spring by the limiting plate fixing screw. The limiting plate fixing screw is a stepped screw. The outer diameter of the positioning bushing is smaller than the inner diameter of the torsion spring and is assembled inside the torsion spring to position it. The two ends of the torsion spring are fixed in the round holes on the mounting plates of the limiting pressure plate and the limiting post resetting mechanism, respectively. After the limiting plate fixing screw is tightened, the limiting pressure plate can rotate freely within the working torsion angle of the torsion spring with the limiting plate fixing screw as the center.

[0007] The parking handle mounting bracket is welded to the vehicle frame connecting bracket. It has a positioning hole on the right side, a limiting flange at the bottom for the parking handle in a stationary state, and the middle surface is the mounting surface for the parking cable.

[0008] Because the cable terminal needs to be assembled to the parking handle via a bracket, the positioning hole of the parking cable is an oblong hole.

[0009] The parking handle mounting bracket has a groove for setting the bushing. The purpose of this groove is to adjust the clearance and ensure that the parking handle moves freely within the groove of the mounting bracket. The parking handle is fixed to the parking handle mounting bracket together with the bushing by the mounting screws and nuts of the parking handle limiting mechanism.

[0010] The brake disc is bolted to the front wheel rim, and the brake caliper is mounted on the brake disc and bolted to the front shock absorber.

[0011] Beneficial effects: Compared with the prior art, the present invention has the following significant advantages: The present invention realizes the slope parking function of the sidecar motorcycle through an independent mechanical structure parking system, which is simple and convenient to assemble, low in cost, and highly versatile.

Detailed Implementation

[0017] The technical solution of the present invention will be further described below with reference to the accompanying drawings.

[0018] Example 1

[0019] The present invention relates to an independent mechanical parking system for sidecar motorcycles, comprising a parking handle 8, a parking handle limiting mechanism 7, a parking handle mounting bracket 11, a parking caliper 3, a parking caliper mounting plate 2, a parking cable 5, an external hex bolt 1, an internal hex screw 4, a screw 6, a bushing 9, and a nut 10.

[0020] The parking handle 8 is fixed to the parking handle mounting bracket 11 along with the bushing 9 via the mounting screws 26 and nuts 10 of the parking handle limiting mechanism 7. The bushing 9 adjusts the clearance to ensure the parking handle 8 moves freely during operation. The parking cable 5 is fixed to the parking handle mounting bracket 11 via mounting screws 6. One end of the parking cable 5 is mounted on the parking handle 8, and the other end is mounted on the rocker arm of the parking caliper 3. The parking caliper 3 is pre-clamped onto the brake disc 15 and then fixed to the parking caliper mounting plate 2 via hex socket head cap screws 4. The parking caliper mounting plate 2 is fixed to the front shock absorber 14 along with the brake caliper 12 of the braking system via hex bolts 1.

[0021] The parking caliper 3 includes a parking caliper body 31, a camshaft assembly 32, a parking caliper rocker arm 33, a rocker arm washer 34, a spacer 35, a lock nut 36, a torsion spring 37, a spring pin 38, a return spring 39, an outer brake pad 310, and an inner brake pad 311. The camshaft assembly 32 is bolted to the outer side of the parking caliper body 31 along with the parking caliper rocker arm 33, the rocker arm washer 34, and the lock nut 36. The spring pin 38 passes through the mounting holes of the outer brake pad 310 and the inner brake pad 311, and the return spring 39 between the mounting holes, fixing the outer brake pad 310 and the inner brake pad 311 within a groove inside the parking caliper body 311. A spacer 35 (equivalent to a brake disc, removed during vehicle assembly) is provided between the outer brake pad 310 and the inner brake pad 311 to prevent the brake pads from contacting each other when not in use.

[0022] The parking handle limiting mechanism 7 includes a limiting pressure plate 21, a limiting post resetting mechanism 22, a limiting plate fixing screw 23, a positioning bushing 24, a torsion spring 25, and a mounting screw 26. The limiting pressure plate 21 is fixed to the limiting post resetting mechanism 22 together with the positioning bushing 24 and the torsion spring 25 by the limiting plate fixing screw 23. The limiting plate fixing screw 23 is a stepped screw. The outer diameter of the positioning bushing 24 is smaller than the inner diameter of the torsion spring 25. It is assembled inside the torsion spring 25 and plays a positioning role for the torsion spring 25. The two ends of the torsion spring 25 are respectively fixed in the round holes on the mounting plates of the limiting pressure plate 21 and the limiting post resetting mechanism 22. After the limiting plate fixing screw 23 is tightened, the limiting pressure plate 21 can rotate freely within the working torsion angle of the torsion spring 25 with the limiting plate fixing screw 23 as the center.

[0023] The brake disc 15 is fixed to the front wheel rim 13 by bolts, and the brake caliper 12 is clamped on the brake disc 15 and fixed to the front shock absorber 14 by bolts.

[0024] The parking handle mounting bracket 11 is stamped and then welded onto the vehicle frame connecting bracket. The ∅6 hole on the right side is the positioning hole 111 of the parking handle limiting mechanism 7, and the small flange at the bottom is the parking handle 8 stationary limiting flange 112. The middle surface is the mounting surface 113 of the parking cable 5. Because the cable terminal needs to be assembled to the parking handle 8 through the bracket, the positioning hole of the parking cable 5 is changed from a round hole to an oblong hole 114, which facilitates the smooth assembly of the cable terminal.

[0025] Example 2

[0026] The operation of the independent mechanical parking system for the sidecar motorcycle of the present invention: When the parking handle 8 is pulled up, the parking cable 5 is pulled by force to rotate the parking caliper rocker arm 33 clockwise (A), the torsion spring 37 is compressed, and the camshaft assembly 32 moves axially, thereby pushing the outer brake pad 310 on the same side to move inward (B) until it clamps the brake disc and achieves the parking effect.

[0027] When the parking handle 8 is pulled to the maximum travel position, press the button 22 of the parking handle limit mechanism 7, and the limit plate 21 will be engaged. The limit mechanism will be activated, the parking handle will remain in the working state, and the parking function will continue.

[0028] When the limit plate 21 is opened, the button 22 of the parking handle limit mechanism 7 automatically returns to its original position, the limit mechanism is no longer working, the parking handle 8 is pulled back to its original position, the parking cable 5 is no longer under force, the parking caliper rocker arm 33 rotates counterclockwise under the action of the torsion spring 37, driving the camshaft assembly 32 back to its original position, the outer brake pad 310 releases the brake disc and returns to its original position under the action of the return spring 39, and the parking system stops working.
