Abstract
The utility model relates to a tread braking unit for the brake of the rolling stock, which comprises a brake cylinder, a mechanism of amplification of the power and a slack adjuster with a brake block holder. The non-deformability of the adjusting screw rod is improved. The flexibility and the accuracy of the brake is ensured. The integral structural style are adopted by the adjusting screw rod and the square head used for pushing the brake head of the utility model. Thereby, the flexural strength is obviously enhanced. The flexible action of the utility model is exactly ensured. The braking performance is safe.
Description
The utility model relates to a kind of brake equipment of rolling stock, in particular for rail vehicles and motor train unit, and the foundation brake of light rail vehicle.
By the tread brake unit of common employing, mainly be by brake cylinder, the enlarger of power and clearance adjuster are formed.Promoting brake shoe and play brake action and wherein directly export braking force, promptly is the adjustment screw mandrel in the clearance adjuster.Because this screw mandrel is that its anti-transverse force is little by joining minute body structure of screw thread with the square toes that directly act on brake head, intensity is low, very easily produces to become curvature shape, thereby influences the alerting ability of tread brake unit, even cause brake failure.
In order to overcome above-mentioned defective, the purpose of this utility model is to improve the non-deformability of adjusting screw mandrel, guarantees flexible, the accuracy of its action.
Technical solution of the present utility model is as follows:
A kind of tread brake unit that is used for the rolling stock braking comprises brake cylinder and the enlarger that is arranged at the power in the cylinder mouth, and with enlarger the direct acting clearance adjuster that has brake head takes place.Adjustment screw mandrel in the described clearance adjuster is an integral structure with the square toes that are used to promote the brake head action, an end of promptly adjusting screw mandrel is a tetragonal body, the length of side of its cross-sectional plane is greater than the screw mandrel diameter, and in the middle, is provided with the through hole that is used to install flat spring along axis direction.
Because the utility model tread brake unit changes main gear screw mandrel in its clearance adjuster and connecting of square toes into integral structure, significantly improved the non-deformability of screw mandrel, strengthened its bending strength, thereby the flexible movements that guaranteed the adjustment screw mandrel are accurate, make its deceleration and stopping performance safe and reliable.Simultaneously, the square toes because of minute body structure are to adopt special material again, the manufacturing cost height, and integral structure need not special material owing to satisfied the requirement of bending strength, therefore the whole cost of its screw mandrel is decreased.
Description of drawings of the present utility model is as follows:
Fig. 1 is the structural representation of this tread brake unit;
What Fig. 2 showed is to adjust screw mandrel.
Below in conjunction with accompanying drawing the utility model is further described.
See Fig. 1, this tread brake unit comprises brake cylinder 1, is arranged on the enlarger 2 of the power in the brake cylinder mouth, and with the enlarger of power direct acting clearance adjuster 3 takes place.Adjustment screw mandrel 4 its front ends in clearance adjuster 3 are the square toes 5 of tetragonal body structure, and screw mandrel 4 is one with square toes 5.Along on the axis direction of screw mandrel, the middle part that is positioned at square toes 5 is provided with the through hole that is used to install flat spring, as shown in Figure 2.When the wedge surface in the enlarger 2 of power acts on the clearance adjuster 3, adjust screw mandrel 4 and move forward, act directly on by brake head 6 by square toes 5 and realize braking on the wheel tread.
Claims (2)
1, a kind of tread brake unit that is used for the rolling stock braking, comprise brake cylinder and the enlarger that is arranged at the power in the cylinder mouth, and with enlarger the direct acting clearance adjuster that has brake head takes place, it is characterized in that the adjustment screw mandrel in the described clearance adjuster is an integral structure with the square toes that are used to promote the brake head action.
2, tread brake as claimed in claim 1 unit is characterized in that an end of above-mentioned adjustment screw mandrel is a tetragonal body, and the length of side of its cross-sectional plane is greater than the screw mandrel diameter, and in the middle, is provided with the through hole that is used to install flat spring along axis direction.
