Filed:

Jul 14, 1982

Appl. No.:

6/398051

Inventors:

David T. Ping - Mentor OH

Philip S. Webber - Chardon OH

Assignee:

Towmotor Corporation - Mentor OH

International Classification:

B60K 1716

US Classification:

180312

Abstract:

This invention relates to an apparatus and method for mounting a transmission (32) in a frame (10) of a vehicle (12) which eliminates the problems of accessibility, complexity and the need to elevate the vehicle for access from beneath. The mounting arrangement has a first trunnion (42) releasably connected to a first side (34) of the transmission (32) which is slidably disposed in an aperture of a first side member (14) of a frame (10) and a second trunnion (52) releasably connected to a second side (36) of the transmission (32) and slidably disposed in an aperture in a second side (16) of the frame (10) and a guide apparatus (72) for slidably connecting a second end (40) of the transmission (32) to the frame (10) and guiding the transmission (32) for movement in directions substantially normal to a transverse trunnion axis defined by said trunnions. Thus, the mounting arrangement eliminates the problems of installation of a transmission from beneath a vehicle frame and facilitates faster installation and removal while providing support for the transmission during installation. The mounting arrangement is particularly useful in a fork lift truck.

Abstract:

Pneumatically operated devices respond to movement of a shift lever by decoupling change speed gears from both the input and output of a transmission and then brake the gears to a stop, shift gear engagements as necessary, release the brakes and re-engage the input and output clutches to re-establish drive at a newly selected drive ratio. A self-cycling control circuit is connected between the shift lever and pneumatic devices to actuate and deactuate such devices as necessary to accomplish a selected shift. The circuit includes means which enables re-engagement of the input and output clutches only after critical gear couplings and decouplings are established together with means which cycles the gears to facilitate engagements and disengagements if these have not occurred in a predetermined time. Means are also provided for preconditioning the system to respond quickly to a subsequent shift lever movement.
