This invention relates to an improved chassis construction particularly for a motor bus.

The main objects of the invention are to provide a chassis of the type which has a centrally located, main longitudinal column on the respectively opposite sides of which are mounted a pair of driving motors; to provide improved motor supporting outriggers from which the motors are suspended so as to be conveniently removable; and to provide overhanging supports of this type from which the motors may be disconnected and removed from the chassis by lowering them from their mounting.

Other objects of the invention are to provide improved spring supporting arms on the central column which extend laterally beyond both sides thereof and form supports for the sprung portion of the chassis; to provide improved Outriggers for supporting a bus body p which are located in related proximity to the spring supporting arms; and to provide means on the spring supporting arms for reinforcing the outer portions of the outriggers.

Further objects of the invention are to provide an improved shock absorber support; to provide a support of this kind which has end portions registering with the intermediate portions of the springs; and to provide bull'- ers on the end portions of the shock absorber supports for cushioning extreme relative movement between the sprung and unsprung parts of the chassis towards each other.

An illustrative embodiment of our invention is shown in the accompanying drawings, in which:

In the form shown, the chassis includes a central longitudinal column 1 having spaced channel bars 2 on its respectively opposite sides, the channel sides of the bars being arranged outwardly. A pair oftransverse motor supports 3 are mounted at their intermediate portions upon the upper: side 4 of the column 1. The members 3 preferably comrise channel bars and their end portions extend laterally beyond the respectively opposite sides of the column 1. These laterally extending end portions are slightly arch shaped and they have downwardly extending extremities 5 which are substantially parallel to the webs of the channel bars 2 of the column.

The channel side of each motor support 3 extends upwardly as shown in'Fig. 3, and a pair of upright gusset plates 6 are secured by rivets 7 to the respectively opposite sides 8 of the channel bars of which the motor supports are formed. The gusset plates of each motor support extend outwardly beyond the opposite sides of the column 1 and they are connected together at their upper ends by a body supporting outrigger 9- which is arranged transversely of the column and which extends outwardly beyond the motor support 3 as shown in Fig. 2. The Outriggers having side flanges 10 which are riveted at 11 to the upper edge portions of the gusset plates 6. This construction forms a tremendous strength of the type shown in Fig. 3. The outer curved portions of the motor supporting members 3 are each rigidly connected to their respective Outriggers by .plates 12 which areriveted at 13 and 14 to the side flanges 10 and of the channels 9 and 3,

tubular structure 016 respectively. If desired, the plates 12 may be formed integral with the gusset plates 6.

Located between the side flanges of each channel .bar 2 of the column 1 are motor mounting brackets 15 of channel shape having side-flanges 16 which are riveted at 17 to the flanges of the channel bar 2. The webs of the motor supporting brackets 15 and the webs of the downwardly extending end portions 5 of the motor supporting arms are provided withpapertures through which bolts 18 extend for supporting a pair of motors 19 which are suspended from the arch shaped end portions of the motor supporting members, one motor being located on each side of the chassis. These motors may be conveniently installed frombeneath the side of the vehicle chassis by raising them into place and they have an unobstructed path through which they may be lowered in removing the motors from the chassis.

Mounted on the lower side of the column 1,

somewhat in advance of the motor supports- 3 is a transverse spring supporting member 20 having end portions which extend laterally from the respectively opposite sides of the column 1. The member 20 has a planular seat 21 by which it is rigidly secured to the lower side of the column by rivets 22 extending through the lower side flange of the web of the channel 2 and through reinforcing brackets 23 which are riveted at 24 to the web of the channel 2. The member 20 is provided for supporting the rear ends of springs 25 on which the rear axle 26 of the bus chassis is mounted. Spring supporting pivots 27 carporting member 31 which has a planular seat 32 that is rigidly secured by rivets 33 to the lower side of the column 1, as viewed in Fig. 6. The transverse member 31 has outwardly extending flanges 34 on each outer extremity of which the'respectively opposite sides of inverted U-shaped brackets 35 are mounted by rivets 36, as shown in Fig. 7. The brackets 35 are elongated at their upper extremities which are located substantially inthe plane of the top side of the column 1 and the inner endsof the upper portions of the brackets 35 abut againstthe side edges of the column 1, as shown in Fig. 6.

Mounted on the top side of the column 1, in registration with the transverse spring sup porting member 31, is a transverse body supporting/outrigger 37 comprising a channel bar which has a flattened intermediate portion 38 restingupon the top of the column and secured thereto by rivets 39. The outrigger 37 extends outwardly beyond the respectively 35. With this construction the spring supporting members 31, which are of heavy metal construction as shown in section in Fig. 7, support the outer portions of the outrigger 37.

The springs 25 of the rear axle of the chassis are suspended in the above described manner from the transverse members 20 and 31. The springs 42 of the front axle 43 are suspended in a similar manner from a transverse member 44 which is substantially identical in construction to the transverse member 20 and the rear ends of the springs 42 are supported by a transverse member, not shown, that is identical in construction to the transverse. member 31 and which also supports an outrigger 45 substantially identical to the outrigger 37 shown in Fig. 6. The identity of the various parts of the chassis reduces the cost of construction thereof materially and simplifies the problems of construction and assembling.

Mounted on the upper and lower sides of the column 1, in registration with the front axle 43 of the chassis are upper and lower

transverse members

46 and 47, respectively which have planular intermediate sections 48 and 49 secured to the top and bottom sides I of the column, respectively by the rivets 17 which secure the parts of the fabricated column together. The end portions of the

members

46 and 47 extend beyond the respectively opposite sides of the column 1 and they converge and are secured together by rivets 50 at their outer extremities. The outer end portions of the upper member 46 are similarly shaped and have side flanges 51 to which gusset plates 52 are riveted at 53. The lower edges of the gusset plates 52 are provided with flanges 53' which are located adjacent the lower side of the outer end portions of the transverse member 47'and secured thereto by rlvets 54.

The above structure provides a partial inclosure at the outer end portions of the

transverse members

46 and 47 in which shock absorbers 55 are located. -Each shock absorber 55 has an arm 56 which is pivotally connected by an adjustable link 57 with the front axle 43 of the chassis. Mounted on the.

outer extremities of the-transverse members 46- and 47 are bufiers 58 which preferably comprise blocks of rubber and which are located in registration with .the central portions of the springs 42 of the front axle. These bufl'ers engage the springs and cushion extreme movement of the sprung and unsprung portion of the chassis towards each other. I

The front end of the column 1 is provided with a body supporting outrigger 59 which comprises a channel bar having a planular intermediate portion which is seated upon and riveted to the top side of the column, as shown in Fig. 10. The outrigger '59 is supported by a transverse member 61 comprising a channel bar having a planular intermediate section 62 which is seated upon, and riveted to the lower side of the column 1. These transverse members extend beyond the respectively opposite sides of the column and the outwardly extending portions of the lower members 61 are inclined upwardly and secured at their extremities by rivets 63 to the side flanges 64 of the outrigger 59 between which they are received as shown in Figs. 10 and 11.
