An activating device, in particular a clutch activating device for vehicles equipped with a clutch pedal mounted on a stationary pivot. The clutch pedal is connected to a drive mechanism controlling the activating force of the pedal. The drive mechanism includes a control lever on which an intermediate lever connected to the clutch pedal is held. The drive mechanism includes a first lever joint with the control lever, which is acted upon by a compression spring and which is swivel mounted on a stationary pivot, as well as the attached intermediate lever. This forms a second lever joint with an activating lever of the pedal. The assembly forms an increasing effective lever arm when the pedal is depressed such that the activating force of the clutch pedal is maintained at a substantially constant level for at least a portion of the clutch disengaging process.

Clutch activating device

A power plant is carried by a body on a three-point support. A front mount of three-point is formed by an energy-absorbing longitudinal support which cooperates with another mount of the support which is constructed as a slide bearing to absorb relative motion of the power plant.

Suspension for a front, especially a transversely-mounted motor vehicle

Locking system for two brake pedals of a motor vehicle such as a tractor, for enabling joint and separate actuation of opposite wheel pairs of the type wherein a bolt is utilized to couple the pedals. In accordance with a preferred embodiment, the bolt is spring biased into a locked position and is operable by the foot of the driver so as to be shifted into an unlocked position. These positions are assumed through the use of stops that are staggered with respect to one another both radially and axially and are mounted so as to be brought into contact with a side wall of one of the pedals by rotational and axial movements of the bolt.

An independently suspended wheel rear axle suspension for motor vehicles of the torsion spring type is improved by the provision of a bolster that is designed for reducing the suspension space requirements, while providing optimal noise damping and stable wheel guidance. The improved bolster includes, according to a preferred embodiment, a thrust bearing, a rigid longitudinal support that is connected to the vehicle body by the thrust bearing for providing only vibration insulation and guiding, a support bearing, and a resilient spring member connected to the vehicle body by the support bearing for receiving the preponderant torque of the torsion spring and the vehicle weight, while providing vibration insulation. The longitudinal support means is mounted so as to be elastically displaceable under the influence of forces in the vehicle longitudinal direction, while being relatively rigid under the influence of forces in the vehicle transverse direction. The spring member is constructed so as to be elastic crosswise to the direction of vehicle travel for correcting for the effects of lateral and peripheral forces on a wheel of the vehicle.

Rear axle suspension

An arrangement for the mounting support of a drive unit of a motor vehicle which consists of an internal combustion engine with a clutch, of at least one change-speed transmission and of an axle gear, whereby preferably the change-speed transmission together with the axle gear is combined into a rear drive unit provided in the rear section of the vehicle and a tubular support member disposed in the vehicle longitudinal direction connects with each other the front drive unit consisting of the engine and the clutch with the rear drive unit; the internal combustion engine arranged in the front section of the vehicle is also drivingly connected with the rear drive unit by way of a drive shaft arranged on the inside of the tubular support member; the internal combustion engine together with the clutch, the tubular support member and the rear drive unit are thereby fastened at the vehicle body, frame or the like by way of elastic members which are mounted within the areas of low vibrations of the aggregates of the drive unit and are retained at least in part within mounting supports that are form-rigid yet vibration and oscillation damping.
