It already works like you expect it to do:

erik@zurix:/tmp/test >mkdir a b
erik@zurix:/tmp/test >touch a/c
erik@zurix:/tmp/test >ls -lR
.:
total 1
drwxr-xr-x    2 erik     users          72 Feb 24 11:49 a/

./a:
total 0
-rw-r--r--    1 erik     users           0 Feb 24 11:49 c

erik@zurix:/tmp/test >chmod -r a
erik@zurix:/tmp/test >ls -lR
.:
total 1
d-wx--x--x    2 erik     users          72 Feb 24 11:49 a/

ls: ./a: Permission denied
erik@zurix:/tmp/test >chmod -x a
erik@zurix:/tmp/test >cd a
a: Permission denied.
