Description
Technical Field
The present invention relates to a vehicle frame assembly for a vehicle and more particularly, but not exclusively, to the mounting of a support structure supporting an evaporative emission control device on a vehicle frame assembly.
Background
It is now desirable to package any additional features of the vehicle to improve the performance of the vehicle or to improve the attractiveness of the vehicle. The high quality specifications of vehicles emerging in the market become critical due to the increased awareness of customers of the requirements for lightweight vehicles, ergonomics, ground clearance, ease of handling, etc. This makes the vehicle functional parts an important aggregate. Many studies have been made to achieve such an object, and techniques are being developed to reduce vehicle emissions, rotational mass inertia of the vehicle, and the like. Thereby increasing the range of vehicle performance and continually reducing emissions into the environment. However, due to the increase in new features based on customer and market demand, vehicle weight increases, which is undesirable. Vehicle weight plays a key role in increasing fuel consumption, increasing emissions, and vehicle mass inertia.

Detailed Description
In order to reduce emissions from the vehicle, an evaporative control unit is used in the vehicle to collect fuel vapors from the fuel tank to reduce the amount of unburned hydrocarbons released to the atmosphere.
The evaporative control unit is an add-on device installed in the vehicle, preferably at the rear side of the vehicle or near the engine and fuel tank assemblies to reduce piping losses, hose length and cost.
Packaging the evaporative control device in a vehicle typically requires modification of the body panels used to package the vehicle components. This complicates the vehicle layout and can compromise the appearance of the vehicle, resulting in a heavy design that adds weight to the vehicle in addition to adversely affecting aerodynamic drag of the vehicle and resulting in poor maneuverability under traffic conditions.
The increase in vehicle size also affects the ergonomics of the rider/rear seat in terms of ground accessibility.
Furthermore, the type of installation of evaporative emission control devices known in the art with available vehicle layouts typically requires an outrigger. In addition to the adverse effects of vibration, potential cracking, breakage, and assembly difficulties, more overhang in the bracket can also result in variations in the position of the evaporative emission control device.
The change in positioning of the evaporative emission control device on the vehicle occurs during manufacturing and during handling of the frame assembly of the vehicle during assembly. The outrigger acts as an obstacle and is more easily deformed under normal operating conditions. In order to prevent the outriggers from deforming, the personnel involved in the assembly process must take extra care. This increases the time required to assemble the vehicle. Furthermore, for various other reasons, if the deformed outrigger is continued and the evaporative emission control device is assembled to the deformed bracket, the desired performance of the evaporative emission control device may not be achieved due to improper assembly.
It is known in the art to mount evaporative emission control devices to a portion of a frame assembly in a vehicle. As the most common practice, evaporative emission control devices are mounted to side pipes of a frame assembly of a vehicle. The side tube of the vehicle frame assembly is a critical part of the frame because it also structurally supports other vehicle components. One of the important components supported by the side pipes is the rear shock absorber of the vehicle. The rear shock absorber also exerts significant dynamic and static forces on the side tubes during vehicle operating conditions. Thus, the side tube is a critical area of the frame assembly. To assemble devices such as evaporative emission control devices, the configuration of the welded joints on the critical side pipes may locally weaken the side pipes of the frame assembly, resulting in weakening of the critical areas of the frame. Thus, the function of other vehicle parts is also affected. Therefore, it is undesirable to weld brackets to welded joints of frame assemblies to install evaporative emission control devices.
However, contrary to the concepts described above, it is not yet desirable to mount the evaporative emission control device directly to the side pipes. Mounting the evaporative emission control device directly to the side tubes can result in inconsistent positioning of the evaporative emission control device due to side tube bending and side tube rebound that can occur during use of the vehicle.
Due to these limitations described above, packaging and installation of evaporative emission control devices is critical and very complex. Accordingly, there is a need for an improved and efficient compact mounting structure for an emission control device that addresses all of the problems detailed above as well as other problems of the prior art. The present invention is solving the same problem.
The present subject matter provides for mounting an evaporative emission control device to a frame assembly of a vehicle.
The evaporative emission control device according to the present invention is packaged between a fuel tank assembly, a utility storage device, and a body side panel of a vehicle.
The evaporative emission control device is positioned adjacent to the engine assembly and the fuel tank assembly. In this way, it is possible to easily connect the fuel tank assembly to the evaporative emission control device, and further connect the evaporative emission control device to the engine assembly, without excessively increasing the hose length, complicating the wiring layout, and the like. This is to reduce the hose length for connection between the above components and to reduce the fuel/fuel vapor travel time and distance.
In another embodiment, the evaporative emission control device is connected to an air filter assembly and fuel will be supplied to the engine assembly, in particular to a combustion chamber in the engine assembly, through the air filter assembly.
The evaporative emission control device and its hoses may be packaged on either side of the vehicle to ensure that the fuel hose and electrical circuit are separated from each other, taking into account the electrical wiring in the vehicle.
The present invention includes a frame assembly for supporting an evaporative emission control device of a vehicle, the frame assembly including a head pipe, a main pipe extending rearwardly from the head pipe, a pair of rear frames extending obliquely rearwardly to the main pipe, a cross member disposed at a rear end and located between the pair of rear frames, and a support structure attached to the cross member. The support structure includes a first attachment member and an extension member. The first attachment member is attached to the cross member. The extension member extends from the first attachment member in the vehicle longitudinal direction. The extension member extends along one of a pair of rear frames with a predetermined distance between the frame and the evaporative emission control device. The extension member is configured to support a portion of the evaporative emission control device.
The evaporative emission control device is mounted to a support structure in which a means is incorporated to securely retain the evaporative emission control device under a variety of road load and environmental use conditions.
The evaporative emission control device is inserted as a subassembly into the retainer member and mounted/inserted onto the support structure. The retainer is configured to be received by the second attachment member along a transverse axis of the vehicle such that the evaporative emission control device is positioned parallel to a longitudinal axis of the vehicle.
In another embodiment, the evaporative emission control device is mounted to the support structure using fasteners.
The support structure for the evaporative emission control device is a removable structure to avoid operational damage due to overhanging the frame structure.
In another embodiment, the support structure is mounted to the frame support structure.
In another embodiment, the extension member is configured to support a portion of the second attachment member. The second attachment member is configured to support a portion of the evaporative emission control device.
The support structure is removably attached to the frame support member. The frame support member is fixedly attached in any one of the lateral portions of the cross member.
The evaporative emission control device is disposed adjacent to and below any one of the pair of rear frames.
The evaporative emission control device is juxtaposed with an upper portion of a rear shock absorber of the vehicle when viewed from a side view.
The extension member comprises a cylindrical cross section, the extension member is configured to comprise a closed loop at one end and open at an opposite end, one end of the extension member is configured to support the evaporative emission control device, and the opposite end is attached to the first connection member.
The support structure includes a first attachment member, a second attachment member, and an extension member. The first attachment member comprises one or more holes to enable attachment with the frame assembly, and the second attachment member is arranged at a distance from the first attachment member. The second attachment member is configured to receive the evaporative emission control device and the extension member is configured to connect the first attachment member and the second attachment member.
According to an embodiment, the first attachment member, the second attachment member and the extension member are fixedly attached to each other.
The second attachment member is bent to form an 'L' shape including a first end and a second end. The first end is attached to one or more surfaces of the extension member and the second end is configured to receive a portion of the evaporative emission control device.
The second attachment member is disposed forward and below the first attachment member, a first axis passing through the first attachment member being parallel to a second axis passing through the second attachment member, the second axis being located below the first axis.
The frame support structure is configured to include one or more apertures. Through these one or more holes, a purge control unit is installed. Thus, the relative positions of the evaporative emission control device and the purge control unit will remain consistent. The purge control valve is disposed above the evaporative emission control device in an installed state. Furthermore, this arrangement provides a reduced hose length for the connection therebetween, as a result of which a low installation cost is additionally achieved.
The frame support structure is welded to a cross member of the frame assembly, the cross member being disposed at a rearmost end of the frame assembly. The cross member is placed over the fuel tank assembly to achieve consistent positioning and maintain the angle of the evaporative emission control device as needed to achieve optimal adsorption and transport of fuel vapors. Accordingly, unburned carbon particles discharged to the atmosphere are reduced.
In another embodiment, the support structure may be mounted directly to the frame assembly without any frame support structure.
The mounting bracket is made up of three pieces, namely a top bracket, a bottom bracket and a link, to reduce the weight and cost of the parts.
In another embodiment, the support structure is a single piece or more than one piece integrated to reduce cost, weight, and manufacturing complexity.
The above-mentioned and other features, aspects and advantages of the subject matter will become better understood with regard to the following description, appended claims and accompanying drawings.
Fig. 1 shows a side view of a typical vehicle, such as a scooter type vehicle. The vehicle has a body frame assembly of several tubes welded together, which typically supports the body of the vehicle. The vehicle has steerable front wheels (101) and driven rear wheels (102). The body frame assembly of a vehicle is an elongated structure that typically extends from a front end to a rear end of the vehicle. It is generally convex when viewed from a side elevation. The frame assembly includes a head tube (not shown), a main frame, and may also have a subframe. The subframe is attached to the main frame using a suitable connection mechanism. The frame assembly is covered by a plurality of vehicle body covers, including a front panel (106), a rear cover (116), a lower side cover (110), and a pair of side panels including a left-hand side panel (115).
The handlebar assembly (108) and the seat assembly (109) are supported at opposite ends of the frame assembly and define an open area therebetween referred to as a floor assembly (119), the floor assembly (119) serving as a step through space. A seat assembly (109) for the driver and rear seat is placed over the fuel tank assembly (118) and to the rear side of the floor assembly (119). A front fender (103) is provided above the front wheel (101) to prevent the vehicle and its occupants from being splashed with mud. Also, a rear fender (104) is placed between the fuel tank assembly (118) and the rear wheel (102), and is located outside in the radial direction of the rear wheel (102). The rear fender (104) prevents rainwater and the like from being splashed up by the rear wheel (102).
An engine assembly (112) is provided to drive a vehicle. The suspension is provided for comfortable steering of the vehicle on the road. A front suspension assembly (not shown) is connected to the front fork (117). The rear suspension assembly includes at least one rear suspension. However, a vehicle having two rear suspensions (i.e., rear suspensions on the left and right sides) is also possible. For the safety of the user and in compliance with traffic regulations, a head lamp (107) is also provided in the front part of the vehicle and a tail lamp (114) is provided in the rear part of the vehicle.
Fig. 2 illustrates a side view of a vehicle frame assembly. In this example, a frame assembly is shown that steps through a saddle-type vehicle. A frame assembly (200) is provided that supports an evaporative emission control device (207) for a vehicle (100). The frame assembly (200) includes a head tube (202), a main tube (203) extending rearwardly from the head tube (202), a pair of rear frames (204) extending obliquely rearwardly toward the main tube (203), a cross member (208) disposed at a rear end and located between the pair of rear frames (204) (as shown in the detailed description of fig. 4), and a support structure (201) attached to the cross member (208). The support structure (201) comprises a first attachment member (201 a) and an extension member (201 b). The first attachment member (201 a) is attached to the cross member (208). The extension member (201 b) extends from the first attachment member (201 a) along the vehicle longitudinal direction (LL'). The extension member (201 b) extends along one rear frame (204 a) of the pair of rear frames (204). The extension member (201 b) is configured to support a portion of the evaporative emission control device (207).
The evaporative emission control device (207) is juxtaposed with an upper portion of a rear shock absorber (205) of the vehicle (100) when viewed from a side view.
The evaporative emission control device (207) is disposed adjacent one lateral side of the fuel tank assembly (118), and is disposed adjacent the engine assembly (112) and the air filter assembly (206).
In this way, the evaporative emission control device (207) is protected by the vehicle components. The hoses between the evaporative emission control device (207) and the air filter assembly (206) and engine assembly (112) are relatively short, thus ultimately reducing costs. In addition, due to the shorter travel path along the shorter hose length, the fuel vapor quickly reaches the engine assembly (112) and is sent again for combustion. As a result, unburned hydrocarbons are reduced, thus reducing emissions output to the atmosphere.
Fig. 3 illustrates a side perspective view of a rear portion of the vehicle with the side body panels removed. The extension member (201 b) extends along one rear frame (204 a) of a pair of rear frames (204) having a predetermined distance (d) therebetween. The predetermined distance (d) ensures that the pair of rear frames (204) are not subjected to any stress due to the mounting of the evaporative emission control device (207) to the cross member (208). Thus, the evaporative emission control device (207) is mounted away from critical areas of the frame assembly (200). The critical area is a portion of the frame assembly (200) that also supports the rear shock absorber bracket (302).
However, the evaporative emission control device (207) is positioned along the longitudinal axis (LL') of the vehicle. The evaporative emission control device (207) is received by the second attachment member (201 c) along the vehicle transverse direction (TT'). This mounting of the evaporative emission control device (207) enables the device (207) to be packaged within the body panel of the vehicle (100). Thus, the width of the vehicle is not increased and no additional effort is required for packaging the device (207).
Fig. 4 illustrates a left side perspective view of a rear portion of a frame assembly of a vehicle with side panels removed. A support structure (201) for supporting a frame assembly (200) of an evaporative emission control device (207) of a vehicle (100) includes a first attachment member (201 a). The first attachment member (201 a) includes one or more apertures (208 ax) (as illustrated in the detailed description of fig. 5) to enable attachment with the frame assembly (200). The second attachment member (201 c) is arranged at a distance from the first attachment member (201 a). The second attachment member (201 c) is configured to receive the evaporative emission control device (207) and includes an extension member (201 b) connecting the first attachment member (201 a) and the second attachment member (201 c). The first attachment member (201 a), the second attachment member (201 c), and the extension member (201 b) are fixedly attached to each other.
The extension member (201 b) comprises a cylindrical cross section. The extension member (201 b) is configured to include a closed loop at one end (201 bx) and open at an opposite end (201 by). One end (201 bx) of the extension member (201 b) is configured to support the evaporative emission control device (207), and the opposite end (201 by) is attached to the first attachment member (201 a).
Fig. 5 illustrates a top view of a rear portion of a frame assembly of a vehicle. A cross member (208) is disposed at a rearmost end between the pair of rear frames (204). The cross member (208) includes a frame support member (208 a). The frame support member (208 a) is fixedly attached to the cross member (208). The frame support member (208 a) includes one or more apertures (208 ax). The one or more apertures (208 ax) are configured to receive the support structure (201). In an embodiment, the support structure (201) is detachably attached to the frame support member (208 a).
Fig. 6 illustrates a left perspective view of a rear portion of a frame assembly of a vehicle with an evaporative emission control device removed. The second attachment member (201 c) is bent to form an 'L' shape including a first end (201 cx) and a second end (201 cy). The first end (201 cx) is attached to one or more surfaces (201 bz) of the extension member (201 b), and the second end (201 by) is configured to receive a portion of the evaporative emission control device (207). The evaporative emission control device (207) is partially enclosed by a retainer (207 a). A portion of the retainer (207 a) is configured to be received by the second attachment member (201 c) along a vehicle transverse axis (TT '), and the evaporative emission control device (207) is disposed parallel to the vehicle longitudinal axis (LL'). The retainer (207 a) enables stable and rigid mounting of the evaporative emission control device (207). The retainer (207 a) prevents the device (207) from being displaced from its installed position during assembly.
Fig. 7 illustrates a side perspective view of a rear portion of the vehicle with the side body panels removed. The second attachment member (201 c) is disposed in front of and below the first attachment member (201 a), a first axis (PP ') passing through the first attachment member (201 a) being parallel to a second axis (CC') passing through the second attachment member (201 c), the second axis (CC ') being located below the first axis (PP'). A frame support member (208 a) is provided on the lateral portion (209). The frame support member (208 a) is configured to support the purge control valve (301) in addition to the support structure (201). Both the purge control valve (301) and the evaporative emission control device (207) are attached to the frame support member (208 a) to maintain consistent relative positioning therebetween. In this way, consistent and desired performance of the evaporative emission control device (207) is achieved. Thus, the final emissions to the atmosphere are also greatly reduced.
Although the present subject matter has been described with reference to particular embodiments, such description is not intended to be construed in a limiting sense. Various modifications of the disclosed embodiments, as well as alternative embodiments of the subject matter, will become apparent to persons skilled in the art upon reference to the description of the subject matter.
