Abstract
A drum-type air brake for a front axle is characterized by comprising a base plate, a dustproof cover, leading shoes, trailing shoes, roller shafts, rollers, shoe shafts, a cam shaft, an adjusting arm, return springs, leading shoe friction plates and trailing shoe friction plates. The dustproof cover, the leading shoes and the trailing shoes are mounted on the base plate, the roller shafts and the rollers are mounted on the leading shoes and the trailing shoes, the shoe shafts are used for connecting the base plate, the leading shoes and the trailing shoes, the cam shaft is mounted in a base plate hole, the adjusting arm is mounted on the cam shaft, the return springs are used for connecting two brake shoes, the leading shoe friction plates are mounted on the leading shoes, and the trailing shoe friction plates are mounted on the trailing shoes. The drum-type air brake is simple in structure and convenient to use, excellent braking efficiency can be kept in a severe environment or when the drum-type air brake is unused for a long time and the like, and maintenance time is prolonged.
Description
Technical field
The utility model relates to a kind of propons drum-type gas brake assembly, belongs to the vehicle braking control system field.
Background technique
Brake assembly is the important spare part of automobile, it is the primary component of realizing wheel braking, the oil gentle two kinds of forms of stopping of stopping are arranged, all be that fixed element by wherein applies braking moment to rotatable member, the latter's angular velocity of rotation is reduced, rely on simultaneously the adhewsive action on wheel and ground, produce the road surface to the braking force of wheel so that car deceleration.All breaks that utilizes the friction of fixed element and rotatable member working surface and produce braking moment all become friction brake.The used friction brake of automobile can be divided into drum-type and disc type two large classes at present.The frictin braek Main Function is: when vehicle was implemented brake command, the friction plate of break contacted with the interior working surface of brake drum by expansion and produces frictional force, thus car deceleration or parking in forcing to travel; Descending makes the automobile speed that travels keep stable; The automobile of stagnation of movement (is comprised on the slope) stablize resident in the original place.The selection of propons break is very crucial, if select improper, can occur before and after braking force do not mate, braking force does not reach many problems such as requirement.
The propons break, because field of employment and Environmental Conditions are different, life cycle is different in size, when being used in crab especially, because long-time break do not work, can return and can not brake and occur that neck stubbornly refuses from the hoof rust, make the break loss of function.The propons break works long hours under muddy road conditions or wet environment, can return and can not brake and occur that neck stubbornly refuses from the hoof rust, make the break loss of function.
The model utility content
In order to overcome deficiency of the prior art, the utility model provides a kind of propons drum-type gas brake assembly, its purpose is: make the break not only can be in rugged environment or do not use for a long time etc. in the situation and keep good Braking efficiency, and also simple in structure, easy to use and prolonged the time of maintaining.
Technical solution of the present utility model:
A kind of propons drum-type gas brake, it is characterized in that: comprise base plate, be installed in dust-proof cover on the base plate and neck from hoof, install neck from the hoof roller shaft and roller, connecting bottom board and neck from the shoe shaft of hoof, be installed in the camshaft in the bottom plate hole, be installed in adjustment arm on the camshaft, connect the backspring of two brake shoes, be installed in neck shoe friction plate on the neck hoof, be installed in from the hoof from shoe friction plate.
The outer surface heat of described shoe shaft is treated to Du Chrome and processes.
The outer surface heat of described roller shaft is treated to Du Chrome and processes.
The steel wire diameter of described backspring is 10mm, and number of active coils is 8 circles.
Dress abs sensor threading hole and dress automatic clearance adjuster support fixed hole are arranged on the described base plate.
Described neck shoe friction plate has square anti-attrition groove in the intermediate portion of installing.
The S curved surface of described camshaft is asymmetric distribution.
The beneficial effects of the utility model:
The design is simple in structure, easy to use, prolonged the time of maintenance, and can be in rugged environment or do not use for a long time etc. in the situation, keeps good Braking efficiency, and simple in structure, easy to use and prolonged the time of maintaining.

Fig. 3: for the utility model is led from the hoof structural representation.
Wherein: 1. base plate 2. negatives 3. dust-proof cover 4. camshafts 5. shoe shafts 6. neck hoof 7. neck hoof 8. roller shafts 9. rollers 10. from hoof 11. from hoof 12. backsprings
Embodiment
The utility model is described in further detail according to accompanying drawing for the below
As shown in Figures 1 to 3: a kind of propons drum-type gas brake, comprise base plate 2, be installed in dust-proof cover 3 on base plate 2 end faces, be installed in camshaft 4 in base plate 1 hole, be installed in neck from the roller shaft 8 on the hoof 6,10 are connected, are installed in roller on the base plate 2 neck from hoof 7,11, connect neck from hoof 7,11 backspring 12, connect neck from hoof 7,11 and the shoe shaft 5 of base plate 2, be installed in adjustment arm 1 on the camshaft 4, be installed in neck shoe friction plate on the neck hoof 6, be installed in from the hoof 10 from shoe friction plate.
The specific works process:
During use, the center positioning hole of base plate 2 is contained on the knuckle seam of vehicle bridge, connect fastening with bolt, adjusting arm is connected with brake chamber, promote or discharge to adjust arm by brake chamber, make camshaft rotate to impel neck from hoof 6,10 opening and closing, realize braking and the release function of break.
This break can use the propons braking system at heavy motor truck, dump truck.
