In the mounted state of the coupling device, the first leg is arranged laterally with respect to the actuating member and the second leg is arranged behind the actuating member. The at least one second coupling element has a first leg projecting from one side of the basic body, and a second leg extending transversely with respect to the first leg. In the mounted state the first hook-shaped coupling element and the second hook-shaped coupling element engage around the actuating member in a form-fitting manner.

A one touch type auxiliary brake for driving training is disclosed. The auxiliary brake includes: a stick member having a handle at an end thereof and extendedly provided by a distance from a passenger seat to a brake pedal shaft of a driver's seat; and a bracket member formed in a hollow rectangular frame shape so that the brake pedal shaft is positioned therein, wherein a first plane is fixedly coupled to an opposite end of the stick member, a second plane is provided to be inwardly inclined to allow the brake pedal shaft to be slidable into the rectangular frame when the brake pedal shaft is fastened thereto, and a fourth plane adjacent to an inclined end of the second plane is coupled to an elastic hinge to be rotated outward and returned to its original position when the brake pedal shaft is fastened thereto and unfastened therefrom.

A brake booster for a braking system of a vehicle including: a valve body to which a booster force is transmittable, a reaction disk, and an output rod, situated on the reaction disk in such a way that the booster force is at least partially transmittable to the output rod via the reaction disk so that the output rod is displaceable in the braking direction, the output rod being pressable counter to the braking direction due to a counter force of a master brake cylinder of the braking system, and the valve body and/or the output rod being formed in such a way that a relative movement of the output rod, aligned counter to the braking direction with respect to the valve body, is limited by an impact of at least one first contact surface of the output rod on at least one second contact surface of the valve body.

A towed vehicle braking system is described that in some embodiments includes a brake pedal connector configured to connect to a brake pedal of a brake of a towed vehicle. A cylinder has a piston connected to the brake pedal connector to actuate the brake of the towed vehicle through the brake pedal connector by applying a positive pressure to the brake pedal connector to move the brake pedal.

A vehicle auxiliary control apparatus includes: an auxiliary steering assembly, including: a frame; an auxiliary steering shaft mounted for rotation in the frame; an auxiliary steering wheel mounted to the auxiliary steering shaft; first and second cable spool assemblies mounted to the auxiliary steering shaft; and first and second cable assemblies coupled to the first and second cable spool assemblies, respectively; and coupling means for coupling the first and second cable assemblies to a stock steering shaft of a motor vehicle, such that rotation of the auxiliary steering shaft causes rotation of the motor vehicle steering shaft.

A method for operating a brake system. A brake request signal is generated, and a setpoint brake pressure required in an active circuit is ascertained. An actual brake pressure is set according to the setpoint brake pressure. A wheel brake actuated by the active circuit is hydraulically decoupled from the pressure generation device by closing an isolation valve, which is situated between the pressure generation device and the wheel brake, the isolation valve is preloaded to a closed state counter to an inflow direction of a volume flow into a brake-side section between the isolation valve and the wheel brake. A hydraulic recoupling of the wheel brake takes place by opening the isolation valve in that the actual brake pressure is set according to the setpoint brake pressure and an opening force is simultaneously applied to the isolation valve such that a compensation of a closing force takes place.

A method of manufacturing vehicle brake boosters includes load testing a plurality of reaction discs and sorting the load-tested reaction discs into multiple, separate batches based on the load test results. A first batch of plunger plates is formed to an axial length to correspond with a first of the separate batches of reaction discs. A first batch of the vehicle brake boosters is assembled with a first one of the multiple, separate batches of reaction discs and the first batch of plunger plates to achieve a target jump-in force. A second batch of plunger plates is formed to an axial length to correspond with a second one of the separate batches of reaction discs. A second batch of the vehicle brake boosters is assembled with a second one of the multiple separate batches of reaction discs and the second batch of plunger plates to achieve the target jump-in force.
