Abstract
A trailer for towing by a power vehicle is provided and generally includes a frame and a tandem wheel assembly. The trailer is provided with a drive assembly having a locking assembly to selectively engage the drive from the motor to the wheels of the trailer. The locking mechanism having a pushing member, and an urging member carrying a plurality of biasing devices and plungers inserted into radially arranged openings in the urging member, such that the plungers are biased against a bearing surface of the driveshaft to urge the driveshaft to shift in a direction, when the clutch assembly allows the driveshaft to shift laterally.
Claims20
A selectively engageable drive system having a driveshaft, a clutch assembly and a locking mechanism, the locking mechanism comprising:
- a pushing member configured to reciprocate between a first position and second position within a housing;
- an urging member in mechanical engagement with the pushing member, the urging member providing a collar with a plurality of radially oriented recesses, a plurality of plungers, and a plurality of biasing devices, with each recess of the plurality of recesses receiving one biasing device of the plurality of biasing devices, and one plunger of the plurality of plungers;
- the plurality of plungers being oriented to be urged against a portion of the drive shaft that is configured to be shifted laterally in a first direction in an amount for effecting engagement of the clutch assembly, and shifted laterally in a second direction in an amount for effecting the disengagement of the clutch assembly, the drive shaft further having an annular protrusion providing a first bearing surface and a second bearing surface positioned on either side of an apex of the protrusion.
A self-propelled vehicle, comprising:
- a frame forming an undercarriage chassis;
- a wheel assembly positioned under the undercarriage chassis and comprising a hub assembly, a drive assembly including a hub, motor, a transmission, a selectively engageable clutch, a driveshaft with an annular protrusion providing a pair of bearing surfaces on either side of an apex of the protrusion, and a locking mechanism having a pushing member, an urging member with a plurality of plungers protruding inwards from the urging member and against the annular protrusion of the driveshaft, wherein the urging on the driveshaft is not effective until the clutch assembly allows the urging to become effective.
