Actuation of a differential lock

Steering arrangement for motor vehicles

Arrangement of a brake in a wheel head equipped with reducing gear

A steered axle assembly comprises a relatively fixed axle beam, a pair of wheel supports pivotal on the axle beam about respective upright wheel pivot axes spaced horizontally apart on the beam transverse to a predetermined horizontal travel direction, an at least limitedly articulated track rod extending horizontally transverse to the travel direction between the wheel supports and having outer ends pivoted on same about respective upright track axes spaced in the travel direction from the respective pivot axes, and an actuator cylinder fixed to the axle beam and having a piston rod forming part of the track rod for relatively displacing the rod and axle beam horizontally transverse to the travel direction and thereby generally identically pivoting the wheel supports about the respective wheel pivot axes. Respective rod and beam abutment formations fixed on the track rod and relative to the axle beam confront each other horizontally transverse to the travel direction. A stop or spacer fixed to one of the formations is engageable horizontally perpendicular to the travel direction with the other formation for limiting pivoting of the wheel supports in one direction relative to the beam beyond an end position with the spacer engaging the other formation.

Pivot limiter for steered wheels

A steered and driven axle-end assembly has a steering knuckle whose inside and outside halves are pivotal about an upright pivot axis. An axle extends into the inside knuckle half and is connected to the inner side of a universal joint whose outer side is connected to one end of a gear train whose other end is connected to a wheel support which is rotatable about a horizontal wheel axis on the outside knuckle half. A pair of roller bearings centered on the wheel axis are spaced axially apart therealong by a spacing which is equal to at most half of the axial distance through which the outside knuckle half extends into the wheel support. Thus the outside knuckle half and associated structure can pivot through a considerable angle relative to the inside knuckle half for minimum turning radius of a vehicle embodying the axle-end assembly.

Steered and driven axle-end assembly

A wheel head for the drive wheel of a heavy duty vehicle provides the hub as a housing which is closed at its outer end by a movable cover and can be opened to allow removal of the planetary gearing and brake. The planetary gearing includes planetary gears journaled directly on the cover and a ring gear in the form of a hollow shaft which encloses the brake and is connected to the axle by a wheel bearing cap which also can be removed through the housing opening when the cover is detached.

Wheel head for driving wheels of vehicles

In a power take-off a spring engages a hydraulically actuated clutch-activating pressure plate to force the same into a neutral position. In one embodiment of the invention a hydraulically operated spring-loaded piston for arresting the rotational motion of an output shaft engages the pressure plate upon shifting thereof into its neutral position and consequent uncoupling of the output shaft from an input or drive shaft. In another embodiment of the invention an annular friction disk slidably connected or splined to the output shaft for stopping the same is clamped between a brake housing and a hydraulically actuated piston. The pistons automatically retract under the action of respective springs upon shut-off of the vehicle engine driving the input shaft and energizing the hydraulic system actuating the plates and the pistons, whereby the angular position of the output shaft may be manually adjusted.
