Description
Technical field
The utility model relates to a kind of braking device of Motor Vehicle, the automatic adjusting play of the electronic type brake arm that especially escalates on mechanical type automatic clearance adjuster basis.
Background technique
In present burst of formula braking technology, the braking function of automobile is to come automobile is realized braking by the brake lining and the friction function between the braking thigh that are installed on the brake shoe, it requires when braking, brake lining should be able to promptly compress brake drum and produce braking moment, and in driving, do not allow the braking plate brake drum of dawdling again, therefore, wish to have a constant rational gap width between braking plate and the brake drum.Because the continuous wearing and tearing of braking plate, brake clearance can prolong, because the air chamber piston stroke extends, has changed the angle of air chamber push rod and brake arm, directly influences effective output of braking moment, is seriously threatening service brake safety.Therefore the drum brake utmost point wishes to install a kind of device that can in time compensate and safeguard a constant rational brake clearance, and the gap of aerobraking drum brake is for this reason adjusted arm automatically and arisen at the historic moment, to adapt to the needs of safety and rules.
Some patents of announcing on the present Chinese patent communique, great majority are the mechanical type automatic compensator, what have can't oppositely increase gap adjustment, changing part to maintenance makes troubles, simultaneously, the machinery maximum drawback of compensation automatically is, one adjust arm manufacture and design finish after its adjusting gap be certain, can not regulate according to weather, road conditions, driver individual's hobby, the brake system rigidity difference of each vehicle of while, the actual gap of its adjusting are also different, thermal expansion in addition, dawdle thereby cause, meeting locking when serious, this is unallowed.
Summary of the invention
The purpose of this utility model provides the automatic adjusting play of a kind of electronic type brake arm, it mainly is that the adjusting gap that solution existing in prior technology machinery compensates automatically is certain, can't regulate according to weather, road conditions or driver individual's custom, the adjusting actual gap difference of different vehicle, thermal expansion in addition, dawdle meeting locking when serious, the technical problem that cost is more high thereby cause.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
The automatic adjusting play of electronic type of the present utility model brake arm, comprise housing, it is characterized in that described housing is provided with the control electromagnet, the control electromagnet is connected with the one-way rotation connecting rod by the electromagnet pull bar, the one-way rotation connecting rod the other end connects adjusts axle, adjust axle and be provided with worm screw, worm screw cooperates with the worm gear that is located at housing bottom; The housing upper end is provided with travel control device.Travel control device can send signal and give the control electromagnet, the circuit of electromagnet can be connected, and electromagnet is finished and once adsorbed the electromagnet pull bar so, and the electromagnet pull bar drives the one-way rotation connecting rod, thereby make worm screw rotate an angle, worm screw drives worm gear and rotates an angle.Thereby braking gap is compensated.
As preferably, described travel control device includes: the stroke that is connected the housing upper end transmits bar, stroke transmits the bar the other end and is slidingly connected in the chute of stroke adjustment dish, and the chute two ends are provided with position limit switch, and position limit switch passes through the electric wire conducting with the control electromagnet.The chute edge of stroke adjustment dish can be carved with some scales, and position limit switch is fixed on the chute two ends by set screw, and brake block when wearing and tearing, the handle stroke of brake arm increases, and the stroke that is contained on the housing transmits bar, will the contacting travel switch, thus send signal.Stroke transmits the diverse location that bar can be installed in housing.
As preferably, described housing is provided with jam at the place, end that adjusts axle, makes materials handling equipment more convenient.
Therefore, the utlity model has the characteristics of electromechanical integration, low cost of manufacture, mechanism is simple, and good stability is easy to maintenance, the characteristics that the life-span is long.Characteristics such as and automatic and manual is one, can regulate the gap according to weather, road conditions or driver individual's custom, can not cause brake appts to dawdle and locking, and cost is lower.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Accompanying drawing 2 is a kind of side structure schematic representation of Fig. 1.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: this automatic adjusting play of routine electronic type brake arm, as Fig. 1, Fig. 2, a housing 1 is arranged, housing 1 is provided with control electromagnet 2, the control electromagnet is hinged with one-way rotation connecting rod 4 by electromagnet pull bar 3, the one-way rotation connecting rod the other end connects adjusts axle 5, adjusts axle one end and is connected with hex head bolt, and the one-way rotation connecting rod is enclosed within on the bolt.Housing 1 is provided with jam 11 at the place, end of the other end of adjusting axle 5.Be fixed with worm screw 6 on the axle body of adjustment axle, worm screw cooperates with the worm gear 7 that is located at housing 1 bottom, is fixed with pressing plate 12 by rivet on the worm gear.The housing upper end is connected with stroke and transmits bar 8, and stroke transmits the bar the other end and is slidingly connected in the chute 9-1 of stroke adjustment dish 9, and chute is an arc, and its two ends respectively are provided with a position limit switch 10, and position limit switch and control electromagnet 2 are by the electric wire conducting.
It is such that the utility model is adjusted the arm working principle: it utilizes the brake arm of regulating the gap automatically to be installed on the camshaft, with integrated camshaft.The box of control position limit switch 10 does not rotate along with camshaft, when the gap of Brake shoe lining and braking strand in default gap, the position limit switch 10 on the brake arm can not transmitted bar 8 by the stroke on the housing 1 and touch, and can not realize regulatory function.When the gap of Brake shoe lining and brake drum surpasses prefabricated scope, promptly brake strip may wear to when surpassing the scope that requires, and this moment, the stroke of corner push rod of brake chamber increased, and the corner of brake arm also increases thereupon.The stroke transmission bar 8 that is contained in so on the housing 1 will be pressed onto position limit switch 10, thereby connects position limit switch.When the brake arm return, can be pressed onto the position limit switch of return again, the circuit of control electromagnet 2 can be connected like this, electromagnet pull bar 3 of control electromagnet 2 meeting adhesives, electromagnet pull bar 3 drives one-way rotation connecting rod 4, thereby make worm screw 6 rotate an angle, worm screw 6 drives worm gear 7 and rotates an angle, thereby braking gap is compensated.When touching on the brake again, stroke transmits bar 8 can leave position limit switch 10, control electromagnet 2 can cut off the power supply, the 3 meeting resiliences of electromagnet pull bar, one-way rotation connecting rod 4 can oppositely change an angle, but connecting rod can not drive worm screw 6 and rotate, because connecting rod 4 is unidirectional driving torques with worm screw 6, can not make the angle forfeiture of adjustment.
