The male splined shaft of towing machine matches with the female splines of brake disc, in the female splines of brake disc, mounting groove is set, and elastic strip is set in mounting groove, rely on elastic strip to eliminate the diameter clearance between the female splines of brake disc and the male splined shaft of towing machine, in the time of towing machine braking or startup, can reduce direct impact and collision between female splines and male splined shaft, reduce noise, improve the reliability of drg.
In order to ensure giving full play to of elastic strip buffer action, preferably, described mounting groove connects disk body on disk body is axial.Be elastic strip extending axially until equate with the axial length of female splines along female splines.
For the ease of the installation of elastic strip and be difficult for deviating from, preferably, the inwall of described mounting groove has the cross section of arc.Described arc is major arc.Correspondingly, described elastic strip is columniform rubber strip.
At least a portion of elastic strip is stretched out mounting groove, and preferably, the top of described elastic strip is along exceeding notch 0.5～3mm.
The top of elastic strip is along referring to the edge of elastic strip towards the disk body axle center of brake disc.
As preferably, described elastic strip and mounting groove interference fit.Elastic strip and mounting groove interference fit, elastic strip is difficult for deviating from from mounting groove.
For the ease of the setting of mounting groove, described mounting groove is between two adjacent key teeth.
In order to obtain better buffering effect, multiple mounting grooves can be set on brake disc, preferably, described mounting groove is 2～6 of the circumferential well-distributeds of drum body.
Between the male splined shaft of towing machine and the female splines of brake disc, set up elastic strip, foregoing technical scheme is, in the key tooth root portion of female splines, mounting groove is set, in like manner, also can on male splined shaft, arrange along the axially extended mounting groove of male splines, elastic strip is set in mounting groove, and at least a portion of elastic strip is stretched out the notch of mounting groove.
The utility model also provides a kind of machine shaft brake, comprises the towing machine main shaft with male splines, and described brake disc is installed on this towing machine main shaft.
The beneficial effects of the utility model are: cylindrical rubber bar is set between female splines tooth top and tooth root, be equivalent to has increased by a bump rubber between the tooth top of female splines and tooth root, eliminate the radially assembly clearance of female splines and male splined shaft, reduced towing machine repeatedly start and brake in impact and collision effect, greatly reduce noise, and can not produce clamping stagnation, make brake disc stable working, improve the serviceability of drg, meanwhile, reduce the accuracy of manufacture of female splines, saved productive costs, reduce assembly difficulty, improved work efficiency.
