摘要:
A master cylinder and brake valve assembly for operating the clutch and clutch brake of a heavy road vehicle is arranged such that up to a first given displacement of the master cylinder piston the clutch release mechanism only is connected to the master cylinder and, above a second further given displacement of the piston, the brake actuator only is connected to the master cylinder, there being a step change in thrust applied to the piston between the given displacements.In a modification, above a third further given displacement of the piston, the brake actuator is reisolated from the master cylinder.

A wheel assembly includes a tire having bead seat angle in the range 10° to 12°, preferably 11°, and an aspect ratio of less than 60%. Reduced bounce and improved bead retention is obtained. The flange is curve and supports the sidewall of the tire in flexure to reduce rolling of the bead seat;
摘要:
A wheel to provide an adjustable track for a vehicle comprises a wheel disc and a rim interconnected by a plurality of circumferentially spaced connections. The connections each comprise a channel member spaced about the rim and receiving a connecting block attached to the periphery of the disc. The channel members are orientated to be parallel to the rotational axis so that forces transmitted from the disc to the rim do not induce forces along the rotational axis. Releasable stops are provided to allow the blocks to be displaced along the channel members and vary the track of the vehicle.
摘要:
A radial tire is provided for use with off-the-road (OTR) vehicles. The tire includes multiple beads, a nylon carcass and multiple nylon plies. The construction prevents slipping and rocking, and zipper-type failures. The tire also has improved lateral stability under load.
