Abstract

The present invention is one four wheel or six wheel differential torsion bar spring vehicle suspension mechanism, which consists of a vehicle body, a four wheel or six wheel independent suspension mechanism, a differential device inside the vehicle body. The independent suspension mechanism has two independent two or three wheel suspension mechanism units separately on two sides of the vehicle body, and the differential device is fixed to these two suspension mechanism units. The present invention has the advantages of less wheels, light weight, low power consumption and easy control, and may be used in lunar rover and planet rover as well as all terrain vehicle and toy vehicle.

Description

technical field [0001] The invention relates to a suspension type vehicle-mounted mechanism. Background technique [0002] The vehicle-mounted mechanism used for lunar and planetary exploration needs to have the characteristics of stable movement attitude, obstacle-crossing ability and strong ability to adapt to terrain. And the patent application publication number is CN1843800A, and the invention patent application date of publication is on October 11, 2006 discloses a kind of " eight-wheel differential - torsion bar spring suspension vehicle-mounted mechanism ", although this vehicle-mounted mechanism is provided with differential device , to solve the stability problem of the main body, so that the pitch angle of the main body is the average value of the pitch angles of the independent suspensions on both sides. However, since the vehicle-mounted mechanism has a large number of wheels, the mass of the entire vehicle-mounted mechanism is large, the power consumption is a...
