Abstract
The utility model discloses a brake for a driving axle of a heavy-duty vehicle. The brake comprises an air chamber bracket and an adjusting arm installed at one end of the air chamber bracket, and is characterized in that a joint bearing is installed on the side of the air chamber bracket neighboring the adjusting arm, and the other side of the air chamber bracket is packed tightly with oil; and the brake is provided with a camshaft installed inside the air chamber bracket. By adopting the novel structure of the joint bearing, the utility model allows the assembled brake to automatically adjust the center of the camshaft to avoid shrinkage, thereby effectively solving the problem that the brake jams because of the shrinkage. The utility model has the advantages of simple structure and low cost.
Description
Technical field
The utility model discloses a kind of heavy goods vehicles and drive the vehicle bridge drg, be specifically related to air chamber bracket assembly in the driving vehicle bridge drg is partly improved.
Background technology
Brake assembly is as the vitals assembly of vehicle bridge part, and its function is automobile in travelling is lowered speed or to stop to travel, or makes that the automobile of stagnation of movement keeps motionless.Because the structure and the performance of brake assembly are directly connected to vehicle, personnel's safety, thereby are considered to the important safety part of automobile, are subjected to general attention.The braking hair fastener is a modal problem at present, it is because in actual production, because the boss height with air chamber support cooperation place in the axle case assy is processed with error, the accumulation errors such as height error that camshaft hole is arrived to the height error and the back-plate center of camshaft hole in air chamber support bottom surface, make in the general assembly process, cause back-plate and camshaft and air chamber support decentraction, use traditional composite bush the hair fastener phenomenon often to occur braking.
Summary of the invention
The utility model provides a kind of heavy goods vehicles to drive the vehicle bridge drg at the deficiency of prior art, and the figure wheel shaft and the air chamber proper alignment of this drg are good, the problem of not braking hair fastener.
Below introduce structure of the present utility model in detail, a kind of heavy goods vehicles drives the vehicle bridge drg, comprises air chamber support and the adjusting arm that is installed in air chamber support one end, and the side that this air chamber support is adjacent with adjusting arm is installed oscillating bearing, its opposite side oil packing.
Optimize, described camshaft inserts in the air chamber support from a side.
Optimize, the oil packing of described air chamber support adopts oil enveloping structure.
The utility model has the advantages that this drg adopts the oscillating bearing new construction, with center that can the automatic compensation camshaft after the drg assembling, be not easy flatly to advance that solved the problem of braking hair fastener effectively, the utility model is simple in structure, cost is low.
Description of drawings
Figure of description 1 is a front view of the present utility model;
Figure of description 2 is made former front view for the utility model.
The specific embodiment
Below in conjunction with Figure of description utility model is done further to disclose.
Embodiment 1:
See also Figure of description, a kind of heavy goods vehicles drives the vehicle bridge drg, comprise air chamber support 1 and be installed in the adjusting arm 2 of air chamber support one end, this air chamber support 1 and adjusting arm 2 adjacent sides are installed oscillating bearing 3, and its adopts oil sealing 5 structures its opposite side oil packing.Camshaft of brakes 4 is installed in the air chamber support.Described camshaft 4 inserts in the air chamber support 1 from the back-plate side.
Its structure and setting-up procedure are: the air chamber support is adorned 1 camshaft 4 places be worked into oscillating bearing 3 and cooperate required size, air chamber support 1 and the adjusting arm 2 adjacent sides oscillating bearing 3 of packing into then, the air chamber support 1 opposite side oil sealing 5 of packing into, with air chamber support 1 assembly and the axle case assy Bolt Connection after installing, fixing.Camshaft 4 is inserted the air chamber bracket assembly from the back-plate side, load onto adjusting arm 2.
Certainly, above-mentioned explanation is not to be to restriction of the present utility model, and the utility model also is not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present utility model, the variation of making, remodeling, interpolation or replacement all should belong to protection domain of the present utility model.
