Abstract

The invention relates to a vehicle-mounted device, in particular to a six-wheel single drive folding extendable rocker arm type vehicle-mounted device. The vehicle-mounted device solves the problems that a plurality of driving sources are required when a folding suspension bracket of a vehicle-mounted mechanism of an existing planetary exploration vehicle is unfolded, an unfolding joint has a complex structure, and the reliability is poor. One end of a front folding suspension bracket mechanism is connected with the front end of a transmission mechanism; the other end of the front folding suspension bracket mechanism is connected with one front wheel; the transmission shaft of each front wheel is connected with the output shaft of one driving motor; one end of a middle wheel vertical arm is connected with the front folding suspension bracket mechanism; the other end of the middle wheel vertical arm is connected with one middle wheel; the transmission shaft of each middle wheel is connected with the output shaft of one driving motor; a differential mechanism is installed in a carriage; two ends of the differential mechanism are respectively connected with two transmission mechanisms; and the differential mechanism is used for controlling the unfolding and folding of two folding suspension bracket systems. The vehicle-mounted device is applied to planetary exploration.

Description

technical field

[0001] The invention relates to a vehicle-mounted device, in particular to a six-wheel single-drive folding and extendable rocker-arm type vehicle-mounted device. Background technique

[0002] Under the limitation of the current space transportation technology and launch cost, the on-board mechanism of the planetary exploration vehicle with foldable and expandable functions has been applied more and more, but the deployment of the existing foldable suspension requires more driving sources. The unfolding joint has complex structure and poor reliability. Contents of the invention

[0003] In order to solve the problem that the foldable suspension of the vehicle-mounted mechanism of the planetary exploration vehicle needs multiple driving sources when unfolded, and the unfolding joint structure is complicated and the reliability is poor, the present invention further proposes a six-wheel single-drive foldable expandable rocker-mounted vehicle-mounted device ....
