truckle: [15] A truckle is a ‘small wooden wheel or caster’. The word was originally used for a ‘pulley’ (an application which has now largely died out), and it was borrowed from Anglo- Norman trocle. This in turn came via Latin trochlea ‘system of pulleys’ (source of English trochlea [17], an anatomical term for a ‘structure resembling a pulley’) from Greek trokhilíā ‘pulley, system of pulleys, roller, etc’. Trucklebed was a term applied to a sort of low bed on casters that could be pushed under a larger bed when not in use, and the notion of sleeping in the truckle-bed, ‘beneath’ someone in the higher main bed, led in the 17th century to the use of truckle as a verb meaning ‘be subservient’.

truckle (v.)youdaoicibaDictYouDict
"give up or submit tamely," 1610s, originally "sleep in a truckle bed" (see truckle (n.)). Meaning "give precedence, assume a submissive position" (1650s, implied in truckling) is perhaps in reference to that type of bed being used by servants and inferiors or simply occupying the lower position.
