Description

Saddle-type vehicle with strut stand sub-assemblies

technical field

The subject matter described herein relates generally to a saddle-type vehicle, and in particular, but not exclusively, to a strut stand subassembly in such a vehicle.

Background technique

Conventionally, two types of vehicle parking devices are used to place a two-wheeled vehicle in a standing state, namely the pillar stand and the center stand. Both types of vehicle parking devices take static loads and help stabilize the vehicle when the vehicle is placed upright. When viewed from the rider's point of view, the strut legs allow the two-wheeled vehicle to lean to its left, while the center leg allows the two-wheeled vehicle to remain upright without leaning against another object. The stanchion feet are provided for balancing the vehicle when the vehicle is parked and are preferred over the central feet for their quick retraction and ease of application.

Description of drawings

The detailed description is made with reference to the two-wheeled vehicle and the accompanying drawings. The same reference numbers are used throughout the drawings to refer to similar features and components.

Detailed ways

Most modern two-wheelers are equipped with both strut legs and center legs. In day-to-day use, riders often choose to apply a strut stance over a central stance because of its ease of access and ease of deployment. Pillar feet are typically mounted to the vehicle frame using pillar foot mounting brackets. The pivot shaft extends laterally relative to the body frame, and the strut legs are pivotable about the axis of the pivot shaft. The stanchion feet in the inclined position must effectively balance the weight of the vehicle in the parked state, and any failure to bear the weight may cause the vehicle to become unbalanced and tip over, causing damage to vehicle components and causing discomfort to the vehicle user.

FIGS. 1A-1C exemplarily show different known configurations of strut stand mounting configurations in two-wheeled vehicles. The pillar feet 104 are mounted to the vehicle frame using the pillar feet mounting brackets 103 . The engine mount bracket 102 forms part of the vehicle frame to which the strut foot mount bracket 103 may be attached. Depending on the frame structure of the vehicle, the mounting of the strut feet to the frame is different. As exemplarily shown in FIG. 1A , the stanchion foot mounting bracket 103 is welded to the rider footrest 101 . In Figure IB, the strut foot mounting bracket 103 is welded to the down tube 105 of the vehicle frame. In FIG. 1C , the strut foot mount bracket 103 is attached to the vehicle's engine mount bracket 102 . In Figures 1A-1B, the strut foot mounting brackets 103 are all subject to substantial welding deformation and high vibration at the haptic point. In FIG. 1C , the overhang due to the configuration in which the strut stand 104 is attached to the strut stand mounting bracket 103 causes instability of the vehicle.

Furthermore, in all of these configurations, the strut foot mount brackets 103 are thicker than the welded frame portions, such as the down tube 105 or the engine mount brackets 102 . The frame parts 102, 105 to which the post foot mounting brackets 103 are attached are either tubular structures or sheet metal structures of lower thickness. When a vehicle is parked using the strut stand 104, the load borne by the strut stand bracket 103 is transferred to these lower thickness frame portions 102, 105, resulting in deflection or deformation of the frame portions 102, 105, and the strut stand mounting bracket 103 Welded joints with frame portions 102, 105 fail. Due to the variation in thickness, a large amount of welding deformation occurs at the welded joint due to poor surface contact between the two components 103 and 102 , 105 .

In addition, the mounting configuration provided on the stanchion foot mounting bracket for mounting the stanchion foot bracket to the frame and the stanchion foot to the stanchion foot mounting bracket results in uneven distribution of loads on the stanchion foot bracket and may Overhang occurs on the side of the surface on which the stanchion foot mounting configuration is provided. Parking of the vehicle may be unstable due to overhang of the strut foot mounting brackets due to the rear axle load of the vehicle, which can then eventually cause the vehicle to tip over.

In other variants of mounting the strut feet, a cross-member with a large cross-section is used, which extends in the width direction of the vehicle and further outwards. This configuration tends to add weight due to extension and also requires modification of the existing frame structure. In addition, since the extension of the cross member does not facilitate the installation of the footrest assembly, many additional separate mounting components for the installation of the footrest are required. In yet another variation of mounting a stanchion foot, a light alloy frame and adjoining reinforcement elements are attached to the stanchion foot mounting bracket for reinforcement. However, the reinforcements are fastened directly to sheet metal supports in the form of engine mounting brackets that tend to deform under bending loads.

Also in some embodiments, when the reinforcement member is used to strengthen the engine mounting bracket, the manufacturing and assembly time and cost associated therewith are increased, and the ground clearance for mounting the vehicle engine is also reduced. In some other embodiments, the strut feet are attached to the vehicle's footrest tube, which again requires additional components, such as a footrest tube. In addition, the position of the stanchion foot in the vehicle needs to be accessible to the rider of the vehicle without significantly affecting the vehicle's center of gravity, and the position of the footrest relative to the stanchion foot needs to be ergonomically friendly to the rider for safe and easy deployment and release of the stanchion feet in the vehicle.

Accordingly, there is a need for an improved vehicle design having a strut stand assembly that ensures balanced parking of the vehicle for extended periods of time, with proper load distribution and reduced welding distortion of the vehicle frame, while also maintaining the stance of the strut stand. Easy and safe unrolling of multiple loops throughout.

The present subject matter has been devised in view of the above and to address other problems of the known art. The designs of the stanchion foot subassemblies disclosed herein address unsteady parking resulting in vehicle unbalance, sliding and tipping effects, improper load distribution of the stanchion foot assembly to the frame, welding distortion on the frame associated with the stanchion footing brackets, Problems with flexing of frame members during load application of the stanchions and poor durability/lifetime of the stanchion assemblies.

In one embodiment of the present invention, a saddle-type two-wheeled vehicle having a strut stand subassembly is disclosed. A saddle-type vehicle includes a frame structure and a strut stand subassembly. The frame structure includes a head tube and a main frame extending rearward from the head tube. The stanchion foot subassembly includes stanchion foot tubes operatively connected to each other, at least one stanchion foot mounting bracket, and at least one stanchion foot integration unit.

The frame structure is supported by the front and rear wheels of the vehicle. The at least one downtube is a left rear downtube and a right rear downtube extending downwardly from the rear curved portion of the main frame.

In one embodiment, the left rear down tube and the right rear down tube are laterally separated by a predetermined distance, forming a receiving space therebetween. The frame structure also includes at least one top power pack mounting bracket positioned adjacent the top portions of the left and right rear down tubes and at least one bottom power pack positioned adjacent the bottom portions of the left and right rear down tubes Unit mounting bracket. In another embodiment, the first cross member mounts a rider footrest assembly of a saddle-type vehicle. In yet another embodiment, the second cross member mounts a center leg subassembly of a saddle-type vehicle. The at least one strut footing integrated unit includes a central receiving portion for receiving the laterally extending end of the second cross member. The at least one stanchion footing integrated unit also includes an extension body portion including at least one mounting arrangement on both sides of the central receiving portion. The extended body portion of the at least one stanchion footing integrated unit includes a front bracket and a rear bracket that form a box-like structure. The central receiving portion of the at least one stanchion foot integrated unit connects the extension body portion and the laterally extending end of the second cross member and extends laterally inward from the rear bracket toward the frame structure when the stanchion foot subassembly is mounted on the frame structure.

The stanchion foot mounting bracket includes a top portion and a bottom portion, the top portion having at least two top mounting configurations corresponding to at least one mounting configuration of the stanchion foot integrated unit for mounting the stanchion foot mounting bracket to the stanchion foot integrated unit , the bottom portion has at least one bottom mounting configuration for coupling the stanchion foot tube with the stanchion foot integrated unit. The central receiving portion of the at least one stanchion footing integrated unit and at least one mounting configuration of the bottom portion of the stanchion footing mounting bracket are collinear when the stanchion footing subassembly is mounted on the frame structure. In one embodiment, the at least two top mounting configurations of the stanchion foot mounting bracket and the central receiving portion of the at least one stanchion foot integrated unit form a top triangle. In one embodiment, the at least two top mounting configurations and at least one mounting configuration of the bottom portion of the stanchion foot mounting bracket form a bottom triangle. The bottom portion of the stanchion foot mounting bracket is inclined at an angle substantially equal to 45° with respect to the top portion. The stanchion foot tube is coupled to the stanchion foot mounting bracket by a U-shaped bracket.

In one embodiment, the first cross member and the second cross member lie in a common vertical plane when viewed in a side view of the vehicle. In another embodiment, the common vertical plane passing through the second cross member is provided substantially at the longitudinal center of the saddle-type vehicle. The ratio of the longitudinal length of the vehicle to the distance between the common vertical plane passing through the first and second cross members and the front wheel axle is approximately 2:1.

In one embodiment, the distance between the point where the strut leg tube ground rests and the vertical plane passing through the longitudinal center of the saddle-type vehicle and the distance between the mounting point of the strut leg tube and the vertical plane of the saddle-type vehicle The ratio is about 2:1. In one embodiment, the angle formed by the stanchion tube mounting point relative to a vertical plane passing through the longitudinal center of the saddle-type vehicle is substantially the same as the ground abutment point by the extrapolated stanchion-footer relative to the saddle-type vehicle The angles formed by the vertical planes are the same.

In one embodiment, the angle formed by the stanchion tube mounting point relative to a vertical plane passing through the longitudinal center of the saddle type vehicle and the extrapolated stanchion foot ground abutment point is formed relative to the saddle type vehicle vertical plane The angle is about 45°. In one embodiment, the vertical plane extends from the longitudinal center of the saddle-type vehicle to the ground level, and wherein the distance between the longitudinal center of the saddle-type vehicle and the ground plane and the distance between the longitudinal center of the saddle-type vehicle and the rear wheels The ratio of the distances between the centers of the axles is approximately 2:1.

Another embodiment of a saddle-type vehicle having a frame structure is disclosed, wherein the strut leg subassembly includes a strut leg tube and at least one strut leg mounting bracket operably connected to each other. In this embodiment, at least one strut foot mount bracket is attached to the bottom engine mount bracket of the frame structure by a reinforcement member.

Positioning the strut foot sub-assemblies according to a governing ratio aids the stability of the strut foot and the vehicle in parked and retracted conditions. The proposed design involves connecting the strut foot mounting brackets to the strut foot integrated unit of the frame, and pivoting to either side of the cross member that provides greater structural strength to the frame. In effect, this design creates a triangular effect that resists bending moments in addition to axial forces. In addition, the bending stress from the strut foot is received equally on both sides by the collar (bushing) and the threaded member of the strut foot integrated unit, so when the strut foot is rotated, the strut stand as described in the prior art Any flexing in the foot mount bracket is completely suppressed. The box-shaped portion of the stanchion foot integrated unit forming a closed loop helps isolate and reduce deflection, thereby absorbing direct loads from the stanchion footing, providing efficient transfer of forces from loads acting on the stanchion footing sub-assemblies to the frame.

The tilted position of the strut feet matches the center of gravity in the longitudinal direction of the vehicle, which helps to balance the weight of the vehicle between the front and rear axles effectively. Pillar footing height is determined relative to vertical center of gravity and tire size, with a 1:2 ratio of mounting height to ground, which helps achieve greater stability in parked conditions. The inclination angle of the stanchion foot, created by a forward angle of approximately 15° and a retraction angle of approximately 90°, helps improve its handling and ensures ease of operation during retraction. Therefore, the pillar stand can be rotated smoothly, and the durability of the side stand is improved. Pillar stand subassemblies can be used as subassemblies to reduce frame weight and packaging requirements. Additionally, the stanchion foot switch assembly and engine stop can be integrated with the stanchion foot mount bracket to provide an alarm and ensure safety during prop foot operation. The stanchion foot subassembly is designed to be deployed in any two-wheeled vehicle that requires the stanchion foot function to balance the vehicle when the vehicle is parked.

Each of these top mounting configurations 501 is positioned in line with the mounting configuration 603 in the extended body portion 602 of the stanchion foot integration unit 406 . Only two top mounting configurations 501 in the top portion 702 of the stanchion foot mounting bracket 404 adjacent the edge of the stanchion foot mounting bracket 404 are shown in FIGS. 7A-7C . However, the number of mounting configurations is not limited to just two; there may be multiple evenly distributed mounting configurations on the top portion 702 of the stanchion foot mounting bracket 404 . The stanchion foot mounting bracket 702 has an irregular shape, similar to the shape of an amoeba. Pillar foot mounting bracket 404 has a top portion 702 having a top mounting configuration 501 and a bottom portion 703 having a bottom mounting configuration 701 separated by angular bends about axis XX'.

The surface 704 of the top portion 702 of the stanchion foot mounting bracket 404 covers only the mounting configuration 603 of the extended body portion 602 and follows the outer contour of the recesses 605a, 605b in the extended body portion 602 of the stanchion foot integrated unit 406. The location of the bottom mounting arrangement 701 is in-line with the central receiving portion 601 of the stanchion foot integrated unit 406 . That is, the shape of the strut leg mounting bracket 404 is such that the frame mounting of the strut leg subassembly 304 and the mounting of the strut leg 405 are arranged in a collinear fashion. Furthermore, the top mounting arrangement 501 is located on both sides of the central receiving portion 601 . Thus, a top triangle shown in phantom is formed between the top mounting configuration 501 and the central receiving portion 601 , and a bottom triangle shown in phantom is formed between the top mounting configuration 501 and the bottom mounting configuration 701 . When the strut stand tube 405 is deployed to park the vehicle 200, the strut stand tube 405 strikes the edge 709 of the strut stand tube 404 and the load carried by the strut stand tube 405 is from the U-shaped bracket in the bottom mount configuration 701 408 is transferred to the central receiving portion 601 connected to the second cross member 402 . The mounting spacing between the top mounting configurations 501 allows for an equal distribution of loads to the top mounting configurations 501 and the extension body portion 602 of the strut footing integrated unit 406 . The evenly distributed load is transferred to the central receiving portion 601 and thus to the second cross member 402 in the frame structure 300 of the vehicle 200 . Due to the triangulation of the top mounting configuration 501 , the bottom mounting configuration 701 and the central receiving portion 601 , the mounting spacing between the top mounting configuration 501 facilitates efficient transfer between the stanchion foot mounting bracket 404 and the stanchion foot integrated unit 406 The load is thus transferred to the frame structure 300 . Thus, the positioning of the stanchion footing integrated unit 406 on the frame structure 300 and the stanchion footing tube 405 creates a rigid support triangle effect and balances the stanchion footing tube load during its application.

Once the accessibility of the strut leg subassembly 304 is secured through its configuration, by determining factors such as the weight of the vehicle 200, the center of gravity of the vehicle 200, the plane of the vehicle on the strut leg 405, the Factors such as points of contact, tire size, vertical loads applied to the strut foot subassembly 405, etc., are important to position the stanchion foot subassembly 304 at a location on the frame structure 300, as in Figures 9A-9B described in the description.

FIGS. 9A-9B exemplarily show schematic diagrams depicting the positioning of the strut leg subassembly 304 relative to the frame structure 300 of the vehicle 200 when in the deployed state. As exemplarily shown in FIG. 9A , the position of the strut stand tube 405 is shown relative to the wheelbase of the vehicle 200 when deployed. "a" represents the wheelbase, that is, the distance between the front axle 204 and the rear axle 205 . "b" represents the distance from the front axle 204 where the strut leg subassembly 304 is installed. "c" represents the distance of the strut footing base 412 from the front axle 204 . The location for mounting the strut foot sub-assemblies 304 on the frame structure 300 is selected at a location where the a:b ratio is approximately 2:1. That is, when viewed in a side view of the vehicle, the first cross-member 401 and the second cross-member 402 lie in a common vertical plane YY', and the common vertical plane YY' passing through the second cross-member 402 is substantially It is provided at the longitudinal center of the vehicle 200 .

When deployed, the position of the strut leg tube 405 is arranged to balance the vehicle's center of gravity in the vertical, lateral and longitudinal directions of forces. The position of the strut leg subassembly 304 effectively transfers weight during application of the strut leg tube 405, and the angle of inclination of the strut leg tube 405 relative to the vertical axis helps offset the weight.

As exemplarily shown in FIG. 9B , a working ratio is determined to position the strut base subassembly 304 on the frame structure 300 relative to the height of the vehicle 200 . The duty ratio is important for determining the position of the strut stand tube 405 and improving the stability of the strut stand tube 405 . The ratio of the tire size of the vehicle 200 to the vertical height of the stanchion tube 405 helps to overcome tipping of the vehicle 200 when the stanchion tube 405 is deployed. In addition, the lateral offset of where the stanchion tube 405 is mounted to the point at which the stanchion tube 405 contacts the ground helps to calculate the ground reach of the stanchion tube 405 and overcome slippage effects when the stanchion tube 405 is deployed.

As shown in FIG. 9B, line OB represents the vertical plane passing through the longitudinal center O of the vehicle 200; point C represents the center of the rear axle 205; ) mounting point on frame structure 300; point D represents the extension of the pillar foot mounting point to the center plane of the vehicle 200; point F represents (in the vehicle vertical position) the point where the pillar foot tube ground abuts; point E represents The extension of the support point F to the vehicle center plane; the point H represents the vertical descent from the support point G to the support plane EF; the point B represents the point indicating the ground plane ; and point A represents the extrapolation of point F (in the vehicle upright state) of the ground of the stanchion footing against point F. To ensure the stability of the vehicle 200 and the strut leg tube 405 in an inclined position, the position of the strut leg subassembly 405 is determined to be configured such that the length OB:length OC is approximately 2:1 and the length FE:length GD is approximately 2 : 1, and the angle (GCD) and angle (CAB) are approximately 45°.

Thus, the positioning of the strut leg subassembly 304 at a location on the frame structure 300 that matches the center of gravity of the vehicle 200 in both the vertical and longitudinal directions, the ratio of tire size to the installation height of the strut leg subassembly 304 , and the distance of the strut leg tube 405 from the vehicle center plane where it is mounted to the point of contact with the ground to help reduce the overhang distance and improve the stability of the strut leg subassembly 304 .

FIG. 10 exemplarily shows a perspective view of an alternative embodiment of a strut foot subassembly 405 mounted on a frame structure 300 of a vehicle 200 . In this embodiment, the strut foot mounting brackets 405 are mounted directly on the bottom engine mounting brackets 311 of the frame structure 300 . The strut foot mount bracket 405 is welded to the bottom engine mount bracket 311 by reinforcement members 1001 that reinforce the junction of the strut foot mount bracket 405 and the connection member of the bottom engine mount bracket 311 . In this embodiment, the strut footing integrated unit 406 is removed, and the reinforcing member 1001 is added.

The design of the pillar stand sub-assemblies in a vehicle according to the present invention provides the following technological advancements in the field of manufacture, assembly and use of the pillar stand sub-assemblies: the pillar stand sub-assemblies are easy to manufacture, assemble, repair, maintain and Modular construction that replaces and reduces associated costs. The location where the strut stand sub-assemblies are mounted on the frame structure of the vehicle does not interfere with the center of gravity of the vehicle, thereby facilitating stable parking, vehicle maneuverability, and stable driving of the vehicle. Due to the spacing of its surface mount configuration and the corner bends on its surface, the stanchion foot mounting bracket does not experience any overhang under load. The structure of the stanchion foot subassembly pivoted to the second cross member and the stanchion foot bracket that houses the stanchion foot tube create a triangular effect. This helps to minimize direct loads to the frame and reduces deflection of the stanchion foot mounting brackets, overcoming the problems of the prior art. The ergonomic position of the stanchion foot relative to the rider is an important parameter defined by the length of the stanchion foot and its offset from the center plane of the vehicle. The forward and retracted angles aid in articulation of the stanchion legs and provide convenience.

The location of the strut stance subassembly ensures the primary purpose of stance operation, the ability to reach the stance from the rider's footrest, and the articulation of the stance during opening and closing. The stanchion foot sub-assemblies can be easily installed into the frame structure of the workstation and also easily packaged to meet the specific requirements of different markets and customers. The pillar foot reinforcements welded to the pillar footing integrated unit at the rear portion serve as support reinforcements that help to withstand bending loads.

The stanchion foot subassembly utilizes the frame cross member and the stanchion footing integrated unit as the central pivot, thereby reducing direct loads and vibrations to the frame during the application of the stanchion footing. Mounting configurations positioned on either side of the frame crossmembers on the stanchion footing integrated units create a triangular effect, providing greater structural rigidity. The Pillar Foot Integrated Unit eliminates the need to use separate stiffeners or ribs to further strengthen the Pillar Foot Mounting Bracket. Efficient weight distribution is achieved through such construction of the stanchion foot subassembly while increasing the durability of the stanchion foot during its operation and use. Welding distortion due to the welding of strut standoffs to the frame is eliminated, resulting in improved frame weld quality and reduced direct loads to frame members.
