Improved Vehicle Chassis and Chassis Assembly Method
03 17
The present invention relates to an improved chassis for a vehicle. More specifically the present invention relates to an improved chassis for a goods vehicle, for example a refuse vehicle, a delivery vehicle or the like. The present invention also relates to a method of assembling an improved vehicle chassis.
The chassis of a conventional goods vehicle, such as a refuse vehicle or a delivery vehicle, typically comprises a frame structure including a number of longitudinal beams and horizontal supports. Components of the vehicle, such as drive shafts, axles, transmission systems and suspension elements, for example, may be located on an underside of the frame structure. Depending on the intended use of the vehicle, an upper surface of the chassis may include a bed, which may form a floor. The chassis, including a bed, may also have a body, including side walls and a roof, to form an enclosed space for housing goods intended for delivery, refuse, etc.
There is a need to reduce the unladen weight of vehicles to improve the efficiency of their operation, reducing fuel usage and pollution. Such improvements would also make electric drive systems more viable. There is also a desire to increase the carrying capacity of vehicles both in terms of volume and weight.
Known refuse and delivery vehicles are powered by diesel engines. There is a growing need for hybrid vehicles (for example diesel-electric, petrol-electric, CNGelectric or LNG-electric) and electric-powered goods vehicles that comply with environmental regulations, in particular relating to carbon dioxide emissions.
As a result of these needs, efforts have been made to simplify and reduce the weight of chassis structures and chassis components.
By way of example, WO 2012/117225 discloses a chassis frame of a heavy goods vehicle. The frame has a bed having an upper skin and a lower skin. The bed includes a drop centre which aligned with the longitudinal axis of the vehicle. A
03 17 plurality of lateral beams are provided between the upper and lower skins to provide strengthening members.
Replacement of known vehicle chassis frames is difficult and time consuming. Furthermore, the replacement or repair of vehicle chassis frames is costly.
According to a first aspect of the present invention, there is provided a chassis for a vehicle, the chassis including a first chassis sub structure that is suitable for mounting at least one of an operator's cab, an engine and a front suspension arrangement, and a second chassis sub structure having at least one longitudinal member fixed to a body of said second chassis sub structure; wherein the first chassis sub structure is mounted to the second chassis sub structure; and wherein the first chassis substructure includes a first pair of plates lying on a first plane and a second pair of plates, wherein the second pair of plates are aligned on separate parallel planes; wherein the first pair of plates is mounted on the first chassis sub structure such that the plane of the first pair of plates intersects the planes of the second pair of plates. The plane of the first pair of plates may preferably be substantially perpendicular to the planes of the second pair of plates.
In this way, the chassis may be disassembled to facilitate the repair or replacement of components of either the first or second chassis sub structure. The invention also enables the first chassis sub structure to be connected to the second chassis sub structure of different vehicle types, for example refuse vehicles or delivery vehicles.
The first chassis sub structure may be mounted to the second chassis sub structure by welding or by an adhesive. Additionally or alternatively, the first chassis sub structure may be mounted to the second chassis sub structure by a plurality of fasteners.
The first chassis sub structure may include a third pair of plates, wherein the third pair of plates are aligned on the parallel planes of the second pair of plates such that the plane of the first pair of plates intersects the planes of the third pair of plates. The plane of the first pair of plates may preferably be substantially perpendicular to the planes of the third pair of plates.
The arrangement of the plates provides the vehicle chassis with the mechanical properties required to resist the forces experienced at the join between the first chassis sub structure and the second chassis sub structure, particularly when the vehicle is used to carry a load. The arrangement of the plates also aids assembly of the chassis.

The support ribs and horizontal supports are positioned to form X-formations between the longitudinal body members 126, 128.
Assembly of the chassis 10 will now be described.
The first chassis sub structure 12 is assembled by connecting, for example by welding, the front cross member 20, the intermediate cross member 22 and the rear cross member 24 to the first chassis rail 16 and the second chassis rail 18. The two side supports 28, 36 are similarly connected to the second chassis rail 18 and the two side supports 30, 38 are connected to the first chassis rail 16.
One end of the upper cross member 26 is fastened to the side support 28, for example with bolts, and the other end of the upper cross member 26 is fastened to the side support 30, for example with bolts. In this way, the upper cross member 26 can provide additional strength to the first chassis sub structure 12, but can also be removed, for example to provide access to components mounted on the first chassis sub structure 12.
The lower frame structure 92 is assembled by connecting, for example by welding, the plurality of horizontal supports 134, 136, 138, 140, 142, 144, 145 between the two longitudinal beams 130, 132.

Similarly, the plurality of support ribs 160, 162, 164, 166, 168, 170, 172 connected to the longitudinal beam 130 and the longitudinal body member 126.
At the rear end of the lower frame structure 92, the lower end support rib 104, the pair of vertical supports 106, 108 and the upper end support rib 109 are connected, for example welded, to define the opening 110.
At the front end of the lower frame structure 92, the upper cross member 112, the pair of vertical supports 114, 116 and the pair of cowl panels 122, 124 and the bulkheads 118, 120 are connected in the configuration shown in Figure 2.
Assembly of the second chassis sub structure 14 is described in the Applicants' copending patent application GB 1515154.1
The chassis 10 is assembled by connecting the first chassis sub structure 12 to the second chassis sub structure 14.
The first chassis sub structure 12 is brought into alignment with the second chassis sub structure 14 such that the locating holes 190 of the first and second forward beam mounting plates 41, 43 are aligned with corresponding holes in the second chassis sub structure 14. Locating pins are passed through each of the locating holes 190 in order to ensure that the first chassis sub structure 12 is aligned correctly with the second chassis sub structure 14. The diameter of the locating pins corresponds to the vertical height of the locating holes 190 of each of the first and second forward beam mounting plates 41, 43 such that the vertical position of the first chassis sub structure 12 relative to the second chassis sub structure 14 is fixed. Side to side movement of the first chassis sub structure 12 relative to the second chassis sub structure 14 is restricted by the location of the first and second forward mounting plates 41, 43 and the first and second rearward mounting plates 40, 42. A controlled amount of movement in the fore and aft direction of the first chassis sub structure 12 relative to the second chassis sub structure 14 to facilitate correct alignment of the first chassis sub structure 12 with the second chassis sub structure 14 is possible as a result of the generally oval shape of the locating holes 190.
Fasteners in the form of threaded bolts are passed through each of the remaining holes in each of the first and second forward beam mounting plates 41, 43 and corresponding holes in the second chassis sub structure 14 and tightened in order to secure the first chassis sub structure 12 and second chassis sub structure 14 in position.
The body mounting plate 32 of the first chassis sub structure 12 is aligned with the bulkhead 118 of the second chassis sub structure 14 and fasteners in the form of threaded bolts are passed through each of the holes 56, 58, 60, 62, 64, 66, 68, 70, 72 in the body mounting plate 32 and corresponding holes in the bulkhead 118 and tightened in position.
Similarly, the body mounting plate 34 of the first chassis sub structure 12 is aligned with the bulkhead 120 of the second chassis sub structure 14 and fasteners in the form of threaded bolts are passed through each of the holes in the body mounting plate 34 and corresponding holes in the bulkhead 120 and tightened in position.
Once the first chassis sub structure 12 is clamped to the second chassis sub structure 14, the locating pins are removed from the locating holes 190. Fasteners in the form of threaded bolts are passed through each of the locating holes 190 and corresponding holes in the second chassis sub structure 14 and tightened in position.
In the embodiment described above, each of the body mounting plates 32, 34 and each of the bulkheads 118, 120 include a plurality of holes and the body mounting plates 32, 34 are mounted on the bulkheads 118, 120 using a plurality of fasteners in the form of threaded fasteners. It will be understood that, in alternative embodiments of the present invention, one or both of the body mounting plates 32, 34 may include a plurality of rearward-facing fixed studs that are received in corresponding holes in the bulkheads 118, 120. Additionally or alternatively, one or both of the bulkheads 118, 120 may include a plurality of forward-facing fixed studs that are received in corresponding holes in the body mounting plates 32, 34. In alternative embodiments the body mounting plates 32, 34 and the bulkheads 118, 120 may be connected by a combination of threaded fasteners and fixed studs.
The second rearward beam mounting plate 42 of the first chassis sub structure 12 is aligned with the front end of the longitudinal body member 126 of the second chassis sub structure 14 and fasteners in the form of threaded bolts are passed through each of the holes 82, 84, 86, 88, 90 in the second rearward beam mounting plate 42 and corresponding holes in the longitudinal body member 126 and fastened in position.
Similarly, the first rearward beam mounting plate 40 of the first chassis sub structure 12 is aligned with the front end of the longitudinal body member 128 of the second chassis sub structure 14 and fasteners in the form of threaded bolts are passed through each of the holes in the first rearward beam mounting plate 40 and corresponding holes in the longitudinal body member 128 and fastened in position.
In this way, the first chassis sub structure 12 is mounted on the second chassis sub structure 14 in six locations and in three planes, thereby providing a secure connection between the first chassis sub structure 12 and the second chassis sub structure 14.
The chassis 10 can be used in the assembly of a vehicle 1 by removing the upper cross member 26, mounting an engine on the first chassis sub structure 12 and replacing the upper cross member 26; mounting an operator's cab toward the front of the first chassis sub structure 12; mounting suspension arrangements on the chassis 10 and mounting an axle to the chassis 10.
The chassis 10 of the present invention is advantageous as the first chassis sub structure 12 and the second chassis sub structure 14 can be separated to facilitate the repair and/or replacement of components of the chassis 10.
This is particularly advantageous as it facilitates the mounting of the drive train in the first chassis sub structure 12 prior to the first chassis sub structure 12 being mounted on the second chassis sub structure 14 to assemble the chassis 10. In this way, the first chassis sub structure 12 and the second chassis sub structure 14 including the body 94 can be manufactured in parallel, facilitating more efficient manufacturing processes.
Furthermore, the chassis 10 is advantageous as it enables the front of a vehicle (supported by the first chassis sub structure 12) to be used on different types of goods vehicle, for example refuse vehicles, delivery vehicles, flat bed trucks, cement mixers or mobile cranes.
In the embodiments described above, the first chassis sub structure 12 is mounted to the second chassis sub structure 14 using a plurality of fasteners in the form of threaded bolts or fixed studs.
