"brake-by-wire" type brake system

A “brake-by-wire” type brake system for a motor vehicle, having a brake pressure sensor which can be activated by a brake pedal of a pedal unit and can be connected to wheel brakes of the vehicle outside the “brake-by-wire” operating mode, having a pressure source which can be actuated by an electronic control unit and can be connected to the wheel brakes of the vehicle in the “brake-by-wire” operating mode, and having a pedal travel simulator which interacts with the brake pedal and is formed by at least one simulator element, and a restoring force which acts on the brake pedal independently of the actuation of the pressure source can be simulated in the “brake-by-wire” operating mode. In order to provide a simpler and more cost-effective “brake-by-wire” type brake system, a force / travel characteristic of the pedal travel simulator is provided in a controllable fashion.

Machine tool and method for machining over-long diameter ratio shaft exceeding machine tool standard

The invention discloses a machine tool and a method for machining an over-long diameter ratio shaft exceeding the machine tool standard. The method comprises the following steps: firstly, leaving a section of chuck dock with an effective length respectively at two ends of a workpiece in advance, and drilling central holes on two end surfaces of the workpiece; secondly clamping one end of the workpiece on a chuck of a headstock, and supporting the other end by a finial on a tailstock; thirdly, coarsely turning the excircle of each section of the workpiece, and reversing the workpiece for turning when a knife rest feeds to the tail end of a knife rest lead rail; fourthly, finely turning the excircle of each section of the workpiece, and reversing and clamping the workpiece for turning when the knife rest feeds to the tail end of the knife rest lead rail; and finally, milling the chuck docks at the two ends and the chamfer angle on a boring lathe, a milling machine or other machine tools. The machine tool and the method for machining an over-long diameter ratio shaft exceeding the machine tool standard achieve the purpose of machining long-shaft parts over 15 m on a common machine tool for machining long shaft parts, thereby reducing the production cost.

Linear spring electromagnetic grill ink jet printing mechanism

This patent describes a shuttered ink jet nozzle having a shutter located between the ink reservoir and an ink chamber so as to allow or restrict the flow of ink between the ink chamber and ink reservoir to thereby cause the ejection of ink from the. chamber, the shutter being actuated on demand. The shutter can an electromagnetic coil mechanism attracting a magnetic plate. The coil is anchored to a wafer and the magnetic plate is connected to a shutter plate and adapted to open and close over a series of shutter holes allowing fluid communication between the ink reservoir and the ink chamber. The actuator can include linear springs so as to amplify the travel of a shutter plate covering shutter holes upon activation of the actuator. The ink reservoir includes ink under an oscillating ink pressure which is ejected from the nozzle chamber when the shutters are in an open position. An array of ink jet nozzles can be constructed and grouped into phase groups and each phase group is activated in turn so as to reduce pressure requirements in an ink jet reservoir. The shutters can be used to cause ink to be ejected from the nozzle chamber, followed by leaving the shutter open during a subsequent high pressure period to allow rapid refill, followed by closing the shutter at the end of a high pressure cycle so as to restrict back flow of ink from the nozzle chamber to the ink reservoir.

Retractable constant force yielding anchor bolt for dynamical pressure soft rock lane

ActiveCN102536283ARealize secondary reinforcementIncrease travelAnchoring boltsConstant forceEngineering
The invention relates to a retractable constant force yielding anchor bolt for a dynamical pressure soft rock lane. The retractable constant force yielding anchor bolt consists of an anchor bolt body, a tray, a pull rod, a pre-tightening adjusting bolt, a main spring, a pin roll, a knife-shaped cam, an auxiliary spring, an anchor head framework, a roller, a roller rack and a nut, wherein the anchor bolt body is in threaded connection with the pull rod; the tray can move along the pull rod under the action of an external force; and in the moving process, a synthetic pre-tightening force to the tray caused by the main spring and the auxiliary spring is basically kept unchanged, namely the constant force is kept. When surrounding rocks of the dynamical pressure soft rock lane are deformed, the tray moves through belt load and yield so as to release the stress. After the surrounding rocks relive the pressure, the tray moves back for strengthening and realizes secondary reinforcing for the surrounding rocks. When the surrounding rocks are repeatedly deformed due to stress disturbance, the anchor bolt can form 'yielding-supporting-yielding circular support and flexible support for the surrounding rocks, and thus the damage on the lane is avoided. The retractable constant force yielding anchor bolt disclosed by the invention is ingenious in design and compact in structure; the tray has long moving stroke; and except an anchor bolt body, other parts of the retractable constant force yielding anchor bolt can be detached for recycling, so that the cost is saved.

Assembled dedicated pedestrian street, pavement method of pedestrian street and design method of pedestrian street

The invention discloses an assembled dedicated pedestrian street, a pavement method and a design method of the pedestrian street, and aims at solving the problem that historical sidewalks in towns and countries, especially streets in old towns, are seriously damaged. The assembled dedicated pedestrian street comprises a street body, matched equipment and a drainage system in an assembling manner, wherein inside a geosynclines, a glass fiber reinforced plastics grid plate bottom and glass fiber reinforced plastics square tube curbs at two sides form a bottom plate to form a bottom plate groove; a medium sand layer, a common permeable brick roadbed, a permeable rubber rick and a rubber blind road brick pavement are arranged inside the groove to form the street body; inner and outer outfalls are formed at two sides of each curb; an inner opening is attached to the pavement; an outer opening is connected with an underground glass fiber reinforced plastics drainage pipeline through a branch pipe to form the drainage system. Table and chair facilities can be manufactured into artware to be fixed on the bottom plate. The pedestrian street is not overhauled, change old parts with new parts, and broadened or dismantled according to the requirements, and all components can be recovered and processed to be recycled, so that the life cycle cost is low. The assembled dedicated pedestrian street can be arranged on the outer surfaces of residential and commercial buildings at the sides of urban and rural public transport roads and highways, streets, parks, fields and other pedestrian floors in a paving manner.
