Abstract

An air brake ( 100 ) includes a brake caliper ( 40, 41 ), at least one leaf spring ( 44, 45 ), and a spring support ( 30 a - e ). The spring support is pushed into a recess ( 42 ) of the brake caliper during assembly prior to being fixed to the brake caliper. The spring support ( 30 a ) includes a visual indicator in the form of a marking ( 38 a ) or the brake caliper includes a visual indicator in the form of an incision. The visual indicator is arranged to indicate the correct depth of insertion of the spring support into the brake caliper.

First claim

The invention claimed is:

1. An air brake ( 100 ) comprising:
a brake caliper ( 40 , 41 ),
at least one leaf spring ( 44 , 45 ), and
a spring support ( 30 a - e ), wherein the spring support is inserted into a recess ( 42 ) of the brake caliper during assembly prior to being fixed to the brake caliper,
wherein one of the spring support ( 30 a - e ) or the brake caliper ( 40 , 41 ) includes a visual indicator configured to align with a corresponding feature of the other of the spring support ( 30 a - e ) or the brake caliper ( 40 , 41 ), the visual indicator configured for adjusting installation of the spring support ( 30 a - e ) in the brake caliper ( 40 , 41 );
wherein the spring support ( 30 a - d ) has at one end ( 34 ) a hole ( 36 ) for a screw connection and has at an opposite end ( 32 ) a marking ( 38 a - d ).

2. The air brake ( 100 ) as claimed in claim 1 , wherein the visual indicator is the marking ( 38 a - d ), wherein the marking is in or on the spring support ( 30 a - d ).

3. The air brake ( 100 ) as claimed in claim 2 , wherein the marking ( 38 c ) is in the form of a hole formed in the spring support ( 30 c ).

4. The air brake ( 100 ) as claimed in claim 3 , wherein the hole extends fully through the spring support ( 30 c ).

5. The air brake ( 100 ) as claimed in claim 2 , wherein the marking ( 38 a ) is in the form of an indentation or a recess formed in the spring support ( 30 a ).

6. The air brake ( 100 ) as claimed in claim 2 , wherein the marking ( 38 b ) is in the form of a sticker or a colored marking disposed on the spring support ( 30 b ).

7. The air brake ( 100 ) as claimed in claim 2 , wherein the marking ( 38 d ) is in the form of an incision or notch extending inwardly from an end ( 32 ) of the spring support ( 30 d ).

8. The air brake ( 100 ) as claimed in claim 2 , wherein the marking ( 38 a - d ) has a spacing ( 32 ) from an insertion end ( 32 ) of the spring support ( 30 a - d ), wherein the insertion end of the spring support ( 30 a - d ) is inserted into the recess ( 42 ) during assembly, and wherein the spacing ( 32 ) is equal to the length by which the spring support ( 30 a - d ) is intended to be inserted into the recess ( 42 ) of the brake caliper ( 40 ).

9. The air brake ( 100 ) of claim 1 , wherein the visual indicator is in the form of the marking ( 38 a - d ), wherein the marking is in or on the spring support ( 30 a - d ) for adjusting the spring support ( 30 a - d ).

10. The air brake ( 100 ) as claimed in claim 9 , wherein the marking ( 38 a - d ) indicates how deep the spring support ( 30 a - e ) is intended to be inserted into the recess ( 42 ) of the brake caliper ( 40 , 41 ) during assembly of the spring support ( 30 a - e ).

11. The air brake of claim 1 , wherein the air brake is attached to a utility vehicle, in particular a heavy goods vehicle or trailer vehicle.

12. An air brake ( 100 ) comprising:
a brake caliper ( 40 , 41 ),
at least one leaf spring ( 44 , 45 ), and
a spring support ( 30 a - e ), wherein the spring support is inserted into a recess ( 42 ) of the brake caliper during assembly prior to being fixed to the brake caliper,
wherein one of the spring support ( 30 a - e ) or the brake caliper ( 40 , 41 ) includes a visual indicator configured to align with a corresponding feature of the other of the spring support ( 30 a - e ) or the brake caliper ( 40 , 41 ), the visual indicator configured for adjusting installation of the spring support ( 30 a - e ) in the brake caliper ( 40 , 41 );
wherein the visual indicator is an incision ( 50 ) in the brake caliper ( 41 );
wherein the incision ( 50 ) is disposed above the recess ( 42 ) of the brake caliper ( 41 ).

13. The air brake ( 100 ) as claimed in claim 12 , wherein the incision ( 50 ) of the brake caliper ( 41 ) has a depth that is equal to the depth to which the spring support ( 30 e ) is intended to be pushed into the recess ( 42 ) of the brake caliper ( 41 ) during assembly.

14. A brake caliper ( 40 , 41 ) for a brake, the brake caliper ( 40 , 41 ) comprising:
a recess ( 42 ) defined in the brake caliper ( 40 , 41 );
a spring support ( 30 a - 30 e ) having an insertion end ( 32 ) configured for insertion into the recess ( 42 ) during assembly; and
a visual indicator associated with the brake caliper ( 40 , 41 ), wherein the visual indicator is configured to align with a corresponding feature of the spring support ( 30 a - e ), the visual indicator configured for adjusting installation of the spring support ( 30 a - e ) in the brake caliper ( 40 , 41 );
wherein the visual indicator indicates how deep the spring support ( 30 a - e ) is intended to be inserted into the recess ( 42 ) of the brake caliper ( 40 , 41 ) during assembly of the spring support ( 30 a - e );
wherein the visual indicator is an incision ( 50 ) in the brake caliper ( 41 );
wherein the incision ( 50 ) is disposed above the recess ( 42 ) of the brake caliper ( 41 ).

15. The brake caliper ( 41 ) as claimed in claim 14 , wherein the incision ( 50 ) of the brake caliper ( 41 ) has a depth that is equal to the depth to which the spring support ( 30 e ) is intended to be pushed into the recess ( 42 ) of the brake caliper ( 41 ) during assembly.
