In-line secondary transaction is described. In an embodiment, an on-line shopping interface is displayed via which an item can be selected for purchase. When a selection is received to initiate a purchase of the item, a determination is made that a secondary transaction is needed to complete the purchase of the item. An in-line secondary transaction user interface is displayed over a portion of the on-line shopping interface to facilitate the secondary transaction where the in-line secondary transaction user interface is displayed to maintain a context of the purchase on the on-line shopping interface. An input of transaction information is received via the in-line secondary transaction user interface to complete the secondary transaction such that the purchase of the item can be completed via the on-line shopping interface.
摘要:
A power tool cooling system comprises a cooling fan disposed on a motor in a position between the upper field coil and the lower commutator. A transmission housing encapsulates the transmission mechanism. During operation, the fan is driven by the motor and draws air axially through the motor and expels the air radially outwardly through holes in the outer housing of the motor. This causes air to be drawn in through the air vents formed on the top of a tool housing, in the side of the housing and between the housing and a battery pack. The cool air flows outside of the transmission housing, but inside the tool housing such that air does not pass through the transmission mechanism. A plurality of motor openings are also formed in the outer housing of the motor to enable cool air to pass into the motor to cool the motor.

A gear wheel is rotatably mounted on a drive shaft. The drive shaft has a plurality of longitudinal splines formed thereon. A drive sleeve surrounds the drive shaft and has a plurality of the inner splines formed on its interior surface. The inner splines slidably intermesh with outer splines of the drive shaft such that the drive sleeve can slide up and down on but cannot rotate relative to the drive shaft. A coil spring biases the drive sleeve downwardly. Drive sleeve teeth are formed around the bottom edge of the drive sleeve. Corresponding gear plate teeth are formed on the upper surface of the gear wheel and are adapted to engage the drive sleeve teeth when the drive sleeve is in its downward most position under the influence of the coil spring. In this position, the gear wheel is operatively coupled to the drive shaft.

A control device is described for a brake system of a vehicle, having a valve control device that is designed to determine, at least taking into account a provided information signal relating to a generator braking moment of a generator that is currently being exerted or is to be exerted, a first target state of a first valve of the brake system that is connected to a master brake cylinder of the brake system and to a fluid storage device of the brake system in such a way that a brake fluid volume can be displaced out of the master brake cylinder into the fluid storage device via the first valve, which is controlled into an at least partly open state, and to output a first control signal, corresponding to the first target state, to the first valve, the first target state being determinable, by the valve control device, for a valve connected via at least one intake line to a brake medium reservoir of the brake system as fluid storage device, as first valve. In addition, a method is described for operating a brake system of a vehicle.

A control device for a braking system equipped with an electric drive device and/or generator device includes: a first receiving device with the aid of which a specified value regarding a brake pressure in at least one wheel brake cylinder of at least one brake circuit is receivable, a second receiving device with the aid of which an actual value regarding a pressure in the at least one brake circuit and/or the brake pressure in the at least one wheel brake cylinder is/are receivable, and a control unit with the aid of which a setpoint mode of the electric drive device and/or generator device is specifiable taking the received specified value and the received actual value into account.
摘要:
A main brake cylinder for a hydraulic vehicle brake system of a motor vehicle is disclosed. The main brake cylinder includes an electric motor that is operated as a generator for decelerating the motor vehicle. For service braking, pressure is applied to a brake circuit by the main brake cylinder and to another brake circuit by a hydraulic pump. In order to reduce a pedal force, a first piston has a smaller piston surface and a second piston only moves if a greater brake fluid volume is required. A preloaded hydraulic accumulator limits an increase in pressure.

A vehicle brake system and method for operating same, having a master brake cylinder, a brake medium reservoir, and a first brake circuit, connected via a reservoir line to the brake reservoir, having at least one first wheel brake cylinder, a first wheel inlet valve associated with the first brake cylinder, a first pump, by which a first brake medium volume is pumpable from the reservoir line through the open first wheel inlet valve into the first brake cylinder, a continuously adjustable first wheel outlet valve, by which a first brake medium displacement from the first cylinder into the brake reservoir is controllable, and a connecting line having a spring-loaded non-return valve, via which a delivery side of the first pump is connected to the brake reservoir, a brake medium displacement from the brake reservoir to the delivery side of the first pump being prevented by the spring-loaded non-return valve.
摘要:
A brake device for motor vehicles has at least two hydraulic brake circuits which are directly connected to a master brake cylinder, as well as an additional brake circuit, which is able to be actuated via a control device, independently of the master brake cylinder. Because of the separate hydraulic brake circuits in the region of the front axle, redundancy is provided, while the third brake circuit, that is able to be actuated independently of the master brake cylinder and typically acts on the rear wheels, during automatic actuation, permits taking into account a braking effect by additional active assemblies, such as a driven generator.
摘要:
A method for blending a generator braking torque of a generator of a recuperative brake system having two brake circuits, including: controlling one of the at least two brake circuits of the brake system in a blending mode, a hydraulic connection between a master brake cylinder of the brake system and a storage volume of the brake circuit controlled in the blending mode being at least temporarily enabled, so that brake fluid is transferred from the master brake cylinder into the storage volume of the brake circuit controlled in the blending mode; and controlling another of the at least two brake circuits in a non-blending mode, a hydraulic connection between the master brake cylinder and a storage volume of the brake circuit controlled in the non-blending mode being interrupted during the non-blending mode. Also described is a control device for a recuperative brake system having two brake circuits.

A control device for a brake system of a vehicle includes a valve control device, using which, while taking into account a provided information signal with respect to a currently exerted or to be exerted generator braking torque of a generator, at least one high-pressure switching valve of a brake circuit of the brake system is able to be controlled into an at least partially opened state such that a brake fluid volume is able to be displaced from a main brake cylinder of the brake system into a storage chamber of the brake circuit via the at least one high-pressure switching valve that has been controlled into the at least partially opened state. Furthermore, a method for operating a brake system of a vehicle is described.
