A vehicle brake cylinder having a brake cylinder and having a piston rod attached to the brake piston provides for the piston rod to be mounted in a ball-receiving sleeve that is secured axially by a latching sleeve. To avoid damage to the brake piston as the latching sleeve is pushed in, the latching lobes have side margins with an inclination. A latching sleeve of said type is also proposed.

A brake device prepares for a failure of a parking brake as an opposed brake device integrated with an electronic parking brake effectively prevents rotation of the piston shaft when the parking piston is driven.

An object of the present invention is to provide a brake apparatus that allows low-cost attachment of a stroke sensor that detects a stroke amount of a brake pedal. The brake apparatus is configured in such a manner that the stroke sensor that detects an amount of an axial stroke of a piston is disposed between one side surface of a master cylinder housing and one side surface of a valve housing, and an output of the stroke sensor is transmitted via a through-hole formed on the valve housing when being transmitted to a control unit attached to an opposite side surface-side of the valve housing.

An object of the present invention is to provide a brake apparatus capable of reducing a size and a weight. A brake apparatus according to the present invention includes a master cylinder housing including a first port that connects an inside and an outside of a cylinder, and a valve housing including an oil passage through which brake fluid introduced from a second port connected to the first port flows. One side of the master cylinder housing where one side surface thereof is located is attached to one side of the valve housing where one side surface thereof is located. The brake apparatus includes a connection portion that connects the first port and the second port between the one side surface of the master cylinder housing and the one side of the valve housing where the one side surface thereof is located. A space opened to respective outsides of the housings is formed around the connection portion

The control apparatus includes operating fluid feeding and delivery lines, a pump-brake having a containment body which defines a sliding chamber and a main piston housed sliding inside the chamber, a control element controlling the movement of the main piston which can be operated by an operator, a control device for controlling the motion transmission of a vehicle or of an operating machine including a fixed part and a moving part suitable for cooperating together, wherein the moving part is suitable for moving through the operation of the control element and includes an auxiliary piston moving between a reference position and at least a detection position and mechanically connected to the moving part to move it with respect to the fixed part during its movement between the reference position and the detection position, the auxiliary piston moving towards the detection position through the movement of the main piston.

A master-cylinder seal housed in a groove around a piston has a core connected to three annular and concentric lips. The core rests against a side of the groove and has: a surface provided with an interior edge followed by a peripheral platter cut by at least one channel, and an exterior crown provided with a connection zone formed by an interruption in the crown and deformable due to pressure within the seal to recreate the crown's continuity and impermeability while facilitating purging the brake system when there is no pressure in the channel and the connection zone.

A pump housing has at least two inlet valve openings located in a first row, at least two outlet valve openings located in a subsequent second row, and at least one high-pressure switching valve opening and at least one changeover valve opening located in a further subsequent fourth row. At least one connection for a wheel pressure sensor is positioned in a third row between the second and fourth rows. At least one connection for a master cylinder pressure sensor is positioned in a fifth row following the fourth row.

In order to improve a master unit for vehicles, in particular for vehicles steered by a handlebar, comprising a housing, a master cylinder unit provided in the housing, an actuation unit for manually actuating the master cylinder unit with a push lever pivotable relative to the housing about a push lever pivot axis and with a push element transmitting a movement of the push lever to the master cylinder unit, which push element is provided on the push lever and, when the actuation unit is manually actuated, acts, via a pressure surface at a contact point, on a contact surface of the master cylinder unit, such that an optimal adaptation to the particular circumstances is possible, it is proposed that, in order to adjust a transmission ratio of the actuation unit with which the actuation unit acts on the master cylinder unit, a lever arm effective in the event of the actuation is adjustable between the contact point and the push lever pivot axis by means of an adjustment device.

A pedal unit includes an accelerator pedal, a brake pedal, a first bracket, a second bracket, and a connector. The first bracket includes a first plate including a first surface and a second surface that rotatably supports the accelerator pedal disposed adjacent to the first surface and the brake pedal disposed adjacent to the second surface. The second bracket includes a second plate including a third surface that rotatably supports the brake pedal disposed adjacent to the third surface of the second plate. The connector connects the first bracket, the brake pedal, and the second bracket in a state in which the brake pedal is disposed between the second surface and the third surface.

A pressure generating device may comprise a piston-cylinder unit having a bilaterally acting piston with two effective surfaces defining two respective, separate working spaces in a sealing manner. Each working space is connected via a hydraulic line to a hydraulic circuit, wherein at least one hydraulic chamber of a consumer is connected to each hydraulic circuit, and wherein a drive drives the piston. Each working space may be in communication with a reservoir for hydraulic medium, via a respective hydraulic line having a respective switching valve. Alternatively, one or both working spaces may be in communication with a reservoir for hydraulic medium via a hydraulic line, with a switching valve in one or both hydraulic lines, and/or a respective outlet valve may be associated with one or more hydraulic chambers of the consumer, and a further connecting line having a switching valve may connect the pressure chambers and/or hydraulic lines.
