pantechnicons

I'm a little stuck... Click here to teach me more about this clue!

'big vans' is the definition.
'pantechnicons' can be an answer for 'vans' (historical vans drawn by horses). I am not sure about the 'big' bit.

'innocent chaps violently shoved' is the wordplay.
'violently shoved' indicates an anagram (letters shoved around).
'innocent'+'chaps'='innocentchaps'
'innocentchaps' with letters rearranged gives 'PANTECHNICONS'.

'into' acts as a link.

Can you help me to learn more?

(Other definitions for pantechnicons that I've seen before include "Large vehicles" , "removing vehicles" , "Large vans" .)

I've seen this clue in The Times.
