$ export

declare -x http_proxy="http://east-kronospan\\edvglu:niva4x4\$\$\$@172.18.4.7:8080"
declare -x https_proxy="http://east-kronospan\\edvglu:niva4x4\$\$\$@172.18.4.7:8080"

From the man page:

       --http-user=user
       --http-password=password
           Specify the username user and password password on an HTTP server.  According to the type of the challenge, Wget will encode them using either the "basic"
           (insecure), the "digest", or the Windows "NTLM" authentication scheme.

           Another way to specify username and password is in the URL itself.  Either method reveals your password to anyone who bothers to run "ps".  To prevent the
           passwords from being seen, store them in .wgetrc or .netrc, and make sure to protect those files from other users with "chmod".  If the passwords are really
           important, do not leave them lying in those files either---edit the files and delete them after Wget has started the download.


This means you should use --http-user and --http-password to specify the credentials for the proxy.

The http{,s}_proxy environment variables are used for getting the proxy URL, but not the username and password.

Please retest with the --http-user and --http-password options

You don't tell me about escape characters so I don't know how here correct write '\' and '$' symbols.  so I tried both variants:

[root@sinuf1 synergy]# wget -v --http-user=east-kronospan\\edvglu --http-password=niva4x4\$\$\$ http://rpms.remirepo.net/enterprise/remi-release-7.rpm

As you see this is also not work for me.
