Protective device for a chassis with articulated frame
The invention relates to the field of municipal and road-building machines and, in particular, to machines having a chassis comprising two articulated semiframes. Protective device made of curved limiter located in the area above the rotary hinge semiframes, defined by the radius from the center of rotation of semiframes fixed with their ends by uprights at the front end and supported by support rollers on vertical racks on the back end. The technical result is protection from injury in case of finding it in the zone folding semiframes when turning the machine. 5 Il. The invention relates to the field of municipal and road-building machines and, in particular, to machines having a chassis comprising two articulated semiframes, and specifically to devices designed to protect against injury, possibly in the zone folding semiframes when turning the machine.Known road-building machine, chassis, which consists of two articulated semiframes on which is mounted cargo handling equipment . The disadvantage of it is that when turning m is given the danger zone, where can a man be. Such a situation can be created and maintenance of the machine.Known to use the text alerts to work with chassis with articulated frame, made in the form of inscriptions, engraved on one of the semiframes, warning about the danger of finding a person between frames  . The disadvantage of this solution is that this warning may not always be done inadvertently, and for other unforeseen reasons.Therefore, the problem to be solved in the proposal the applicant is creating a reliable protective device to prevent a person staying in the danger zone.It is also known chassis multifunction machine for mounting interchangeable working equipment and municipal purposes, including articulated frame, consisting of two front and rear semiframes .The downside of it is the lack of devices that prevent exposure in the hazardous zone folding of semiframes.The proposal of the applicant are considered in relation to the specified chassis.Thus the solution of the problem posed in this proposal lies in the fact that the protective ostego limiter, located in the area above the rotary hinge semiframes, defined by the radius from the center of rotation of semiframes fixed with their ends by uprights at the front end and supported by support rollers on vertical racks on the back end.In Fig. 1 shows a General view of the protective device from the side; Fig.2 - the same in plan; Fig.3 - view page a in Fig.1; Fig.4 - node In Fig.2; Fig.5 is a section along B-B in Fig.4.Arcuate stopper 1 has a shape in plan, defined by the radius D, and secured to the uprights 2 and 3 with their ends 4 and 5. Columns 2 and 3 are installed on the front end 6 of the chassis 7, and the rear section 8 installed rack 9 on the upper parts of which are mounted rollers 10 that its bottom surface rests limiter 1. The limiter is made of two strips 11, interconnected by spacers 12.Works as a protective device in the following way. When turning semiframes 6 and 8 their corners 13 and 14 closer together, reducing the distance between them. The limiter 1, turning together with the front end 6, is rolled over the support rollers 10 rear semi-frames 8 and constantly overlaps the danger zone D, preventing the possibility of finding in her the human is, participating in the process of operation of the machine with articulated frame.Sources of information 1.

ClaimsProtective device for a chassis with articulated frame including front and rear semi-frames, characterized in that it is made of arched limiter located in the area above the rotary hinge semiframes, defined by the radius from the center of rotation of semiframes fixed with their ends by uprights at the front end and supported by support rollers on vertical racks on the back end.
SUBSTANCE: group of inventions relates to driver's aid systems and active safety techniques for vehicles, in particular to hitch angle sensor, which can be used together with aid system in reverse motion with trailer. Hitch angle sensor unit comprises separator, made with possibility of fixation between coupling ball and mounting surface on vehicle, component, having magnetic part and connected to separator with possibility of rotation around axis, formed by coupling ball, connecting element for component attachment to trailer and magnetic field sensor, connected to separator and determining the of component turning position in order to determine hitch angle. Magnetic part has arched shape, having essentially constant width and central point shifted relative to said axis formed by coupling ball.
EFFECT: enabling higher accuracy of vehicle with trailer control in reverse motion.

SUBSTANCE: system of the trailer (102) connection or disconnection with the vehicle (101) contains the towing unit (201), mounted on the vehicle (101), the trailing arm (103), mounted on the trailer (102), the engine, mounted in connection with the towing unit (201), and the engine control unit. The towing unit (201) is controlled by the engine and is capable to move in all directions and automatically connect to the trailing arm (103), mounted on the trailer (102), when they are within the predetermined radius from each other. The towing unit (201) is automatically centered in the driving position after it is connected to the trailing arm (103).
EFFECT: simplification of the vehicle-trailer connection and disconnection and the ability to retract the towing unit under the vehicle, when it is not in use.

FIELD: transport engineering.
SUBSTANCE: articulated joint is provided between trailer and driving part of vehicle. Said articulated joint provides connection and disconnection of trailer and driving part of vehicle. Passage enclosed in corrugated case is provided between driving part of vehicle and trailer. Articulated joint includes two brackets arranged diagonally relative to each other. Brackets are connected on ends by cross-members which can be attached to or disconnected from vehicle. To connect trailer cross-member with driving part of vehicle at least one, and better two, couplings, each with two coupling members, are provided being arranged at a distance from each other. Both coupling members can be connected with possibility of release by means of hydraulic, pneumatic, mechanical or electric drive.
EFFECT: simplified connection and disconnection of trailer and vehicle.

SUBSTANCE: invention pertains to devices for protecting track joints between rotating plates and a corrugated joint between two loosely coupled parts of a vehicle. The corrugations have two sidewalls, which are joined together by at least, the roof of the corrugations. The enclosure of track joints similar to the corrugations of the joint has separate waves or folds. Adjacent waves or folds are joined together at least, in the regions of their crests by clamp plates. The clamp plates, through at least one their ends, are vertically fixed on the side wall with provision for movement. The folds or waves of the corrugations in the region of their direction to the enclosure of track joints of the crest, have bushings for movable fixing of clamp plates to the enclosure of track joints.
EFFECT: increased mobility of corrugations.
