The invention refers to an apparatus for the control of brakes in bicycles and the like, to be used, in particular, for disc brakes mounted on bicycles and comprising a pump able to push fluid into a hydraulic circuit connected to the brake, characterized in that the pump is held inside the handlebar or a part associated therewith.

The object of the present invention is to exhibit the function of a throttle valve mechanism without making the whole of a master cylinder large-sized and to simplify the structure and to reduce the number of pieces of parts. In order to attain this object, the present invention has throttle valve mechanisms with a floating valve body which sits and throttles the flow of the hydraulic fluid to the reservoir from the pressure generating chambers when the pistons operate and which opens when the pistons do not operate, and the throttle valve mechanisms are arranged in the fluid passage for the supplementation of the hydraulic fluid, and the throttle valve mechanisms have a floating valve body with a throttle passage and a valve seat with and from which the floating valve body is brought into contact and is separated, and the valve seat is provided at the tip of the connecting portions to the cylinder body of the reservoir.

The present invention relates to a connecting unit for the transmission of pulling movements to one end of at least one bowden cable, in particular for a parking brake of a vehicle. The present invention further relates to a method for establishing a connection between a bowden cable and a pulling element for the transmission of pulling movements, as it is preferably used during the assembly of parking brakes in vehicles.The connecting unit comprises a support with at least one opening for the mounting of the connecting unit, a pulling element with at least one receptacle for the end of the at least one bowden cable and a guiding element, where the end of the at least one bowden cable can engage the receptacle, and the guiding element is arranged between the at least one opening of the support and the at least one receptacle. The guiding element deflects the end of the at least one bowden cable under a movement in direction of the receptacle through the at least one opening of the support to the side to engage the receptacle.

A brake beam structure comprising compression and tension members having an "u" shaped cross section including two side walls and forming a housing, two end extensions having a quadrangular cross section including two side walls, a fulcrum coupled to the compression and tension members and two brake heads, in which: the ends of the compression member are placed inside the housing of the unshaped cross section of the tension member and each of the end extensions are placed inside the housing of the channel shaped cross section of the compression member, the brake beam having two fasteners passing through holes placed at the ends of the tension and compression members at each of "u" shaped cross section side walls and through holes placed at the side walls of the end extensions in order to fasten the tension member, compression member and end extensions, and in which the brake heads are welded to the ends of the tension member.

A slippage preventing system for vehicular hill starting is mounted on an axle of driven wheels by a one-way brake starter through a support. The one-way brake starter comprises a ratchet wheel, a flywheel in a pawl structure or a ratchet-gear wheel in a shell, a rack push rod meshed with the flywheel in a pawl structure or the ratchet-gear wheel and a return spring on the rack push rod and a truckle, mounted on a same shaft with the flywheel or the ratchet-gear wheel, outside the shell. The slippage preventing system is controlled by a hydraulic passage or an inhaul cable connected with the same and disposed in a cab. During hill starting, the truckle is combined with a rim part of a brake disk or a hub, when slippage occurs, the rotating rim of the brake disk or the hub drives the truckle outside the shell and the flywheel or the ratchet-gear wheel in the shell to poke the rack push rod outwardly so as to compress an auxiliary brake pump piston at the position, braking is achieved by the aid of the hydraulic passage connected with the auxiliary brake pump and a driven wheel brake caliper or an auxiliary brake caliper, and braking stops when a vehicle advances.

A park-brake actuator includes a cam including first serrations and an open-ended slot, a piston including second serrations displaceable relative to the cam in response to variable pressure applied to the piston, a spring, and a rod including a pin urged by the spring toward the slot and contact with the first and second serrations, the pin moved by piston displacement from the slot, onto one of the first serrations to a flat-tow position.

A drivetrain for a motor vehicle has a friction clutch for transmitting drive torque for the motor vehicle and has an actuator arrangement for actuating the friction clutch. The actuator arrangement has a first actuator which is designed to close the friction clutch quickly with little force expenditure in order to thus quickly close up the play which is present in the open state of the friction clutch. The actuator arrangement has a second actuator which is designed such that, with a small stroke, it applies a large force for actuating the friction clutch in order to keep the friction clutch closed with little energy expenditure.
