Abstract
The utility model discloses an improved structure of an automotive adjusting arm, comprising a manual adjusting arm which is composed of a worm, a worm wheel and an adjusting arm shell, characterized in that in the manual adjusting arm, an automatic adjusting device composed of a compensating plate and a rack is arranged. The compensating plate drives the rack to move, and a transmission structure comprises the rack and the worm. The utility model can automatically adjust the brake clearance in the movement of the automobile, the availability of automobile brake is ensured, and the traffic accident caused by the braking failure is decreased. Simultaneously, the cost price of the automotive maintenance and repairs is decreased, and the utilization ratio of the automotive is enhanced.
Description
The utility model relates to a kind of automatic regulating apparatus of vehicle brake gap, is a kind of structure-improved of automobile adjusting arm specifically.
At present, domestic big-and-middle-sized automobile all produces friction force between employing braking hub and the friction lining and brakes in S camshaft brake system.The gap of braking hub and friction lining becomes big along with increasing of number of times of braking.When gap increase arrives certain numerical value, braking failure, safety factor of travel diminishes.Now, the method that overcomes braking failure is, on hand regulation arm, returns polyphony examination with spanner by the Automobile Service personnel, and the braking hub and the gap of friction lining are returned in the safe and effective number range, and the assurance vehicle normally moves.
The purpose of this utility model is to provide a kind of brake clearance to get final product hand adjustment, can realize the structure-improved of self-align automobile adjusting arm again.
To achieve these goals, the utility model adopts following technology, a kind of structure-improved of automobile adjusting arm, comprise the hand regulation arm of forming by worm screw, worm gear and adjusting arm shell, it is characterized in that: the automatic mechanism of being made up of compensation plate and tooth bar is set in the described hand regulation arm, compensation plate drives the tooth bar motion, and tooth bar and described worm screw are formed drive mechanism.
The utility model good effect is, when the gap increase of braking hub and friction lining arrives certain numerical value, before braking failure, the gap of its energy automatic compensation braking hub and friction lining, timely in vehicle operating, compensation becomes big abrasion amount because of the braking increased frequency, make the gap of braking hub and friction lining be in safety all the time, in the actv. number range, thereby guarantee the validity of automobile brake, the traffic accident that minimizing causes because of braking failure reduces the vehicle maintenance and repair cost, improves the automobile degree of utilization.When automatic compensation is malfunctioning, can also implement hand adjustment.
Below in conjunction with drawings and Examples the utility model is elaborated.
Fig. 1 is the brake system of car structural representation;
Fig. 2 is an orthodox car hand regulation arm structural representation;
Fig. 3 is preferred embodiment structural representation of the utility model.
At first see also illustrated in figures 1 and 2.Traditional hand regulation arm 10 mainly is made up of adjusting arm shell 13, worm screw 11 and worm gear 12.With spanner rotary worm 11, worm gear 12 and camshaft 1 rotate thereupon, and brake shoe brake cheek 3 spreadings make friction lining 2 to braking hub 4 medial movement, thereby reach the gap of adjusting braking hub and friction lining.
See also Fig. 1 and shown in Figure 3 again.The utility model is that an automatic mechanism 20 is set on the basis of traditional hand regulation arm 10, and this automatic mechanism 20 is made up of compensation plate 21 and tooth bar 22, and compensation plate 21 drives tooth bar 22 motions, and tooth bar 22 is formed drive mechanism with worm screw 11.When the gap of braking hub 4 and friction lining became big because of the braking increased frequency, the skew of adjusting arm 10 increased naturally.Because of compensation plate 21 1 ends are fixed on the support of camshaft 1, thereby relative displacement angle of adjusting arm 10 and compensation plate 21 generations, the displacement angle size is directly proportional with the gap change of friction lining and braking hub.Compensation plate 21 drives tooth bar 22 motions, and tooth bar 22 transmission worm screws 11 make camshaft 1 rotate an angle, adjust the gap of 2 of braking hub 4 and friction linings, realize automatic compensation.When automatic compensation was malfunctioning, its hand adjustment performance was constant.
