A manual park release device includes a base portion. A handle portion is rotatably coupled to the base portion to move from a retracted position to an extended position. The handle portion during rotation toward the extended position exerts a pulling force to displace a tension cable connected to an automatic transmission of an automobile vehicle to change from a first park gear to a second neutral gear. A first locking feature releasably restricts rotational movement of the handle portion away from the retracted position. A second locking feature releasably restricts rotational movement of the handle portion away from the extended position.

Electromechanical actuator to operate a component of a vehicle provided with a housing formed by a lower element and a lid; a transmission arranged inside the housing and comprising an output shaft provided with a first symmetry axis and an intermediate shaft, which meshes with the output shaft and is provided with a second symmetry axis transverse to the first symmetry axis; and a pair of electric motors also arranged inside the housing; wherein each of the two electric motors rotates the output shaft through the intermediate shaft and wherein the two electric motors are provided with respective rotation axes parallel to each other and transverse to the first symmetry axis.

A traction assembly for terrestrial traction machines, which includes at least one gearmotor adapted to be associated with a track or wheel of the terrestrial traction machine, and a parking brake of an electromagnetic type which is associated with the gearmotor, and wherein the parking brake is of a multi-dry-disk type and is interposed between the driving component of the gearmotor and a speed limiter of the gearmotor.

A measuring device (60) is configured for measuring forces or torques between a motorized vehicle (1) and a trailer or attachment which is towed or pushed thereby. The measuring device (60) has at least three sensor elements (79, 80) arranged on a carrier (71), transversely with respect to a virtual longitudinal axis of the motorized vehicle (1) and spaced apart from one another. The measuring device (60) is arranged in a coupling region between the motorized vehicle (1) and the pulled or pushed trailer or attachment. In order to transmit their measured values, the sensor elements (79, 80) are connected to an evaluation device (40), which is configured to convert these measured values into signals for force displays and/or torque displays according to magnitude and direction.

A method, apparatus and vehicle for controlling a ride level for a vehicle having at least one first axle having a first air suspension and/or one second axle having a second air suspension, a parking brake and an operating brake, including: reading a ride level variation signal, indicating a ride level variation to be performed; providing a parking break release signal to an interface to a parking brake valve that, responding to the ride level variation signal, releases and engages the parking brake installation, the parking brake release signal being for actuating the parking brake valve for releasing the parking brake installation; and providing a first control signal to an interface to a first valve of the first air suspension and/or a second control signal to an interface to a second valve of the second air suspension while using the ride level variation signal for performing the ride level variation.

In the park lock arrangement according to embodiments, a pivoting park pawl is arranged with a roller member against which a lower bearing surface of an actuating member is configured to bear for controlling the park pawl to pivot between a park release position and a park lock position. An upper bearing surface of the actuating member is further configured to bear against an actuator support roller being configured to assist the actuating member in pressing against the roller member of the park pawl to cause the park pawl to pivot. The roller member and the actuator support roller will decrease frictional force arising when the actuating member moves into contact with the roller member for pivoting the park pawl.

An electric travelling vehicle including: a motor controller configured to control an electric motor based on displacement of a steering operation part to a forward travel position, a neutral position, and a rearward travel position, a brake controller configured to bring an electromagnetic power-off brake into a released state or a braking state; and a travel state detector configured to detect a travelling state that is accompanied with the released state, a stopped state that is accompanied with the braking state, and a transit stopped state that is accompanied with the braking state.
