Abstract

The invention discloses an independent traveling unit comprising a hydro-pneumatic spring cylinder, a steering device, a bracket, a speed reducer, a motor and a wheel assembly, wherein the hydro-pneumatic spring cylinder is fixedly connected with a frame; the steering device is arranged on the hydro-pneumatic spring cylinder and can rotate around the hydro-pneumatic spring cylinder; one end of the bracket is fixedly connected with one end of the hydro-pneumatic spring cylinder, the other end of the bracket supports the motor; and the speed reducer is arranged between the motor and the wheel assembly and can drive the wheel assembly to rotate. The invention also provides a vehicle comprising the independent traveling unit. According to the technical scheme provided by the invention, a driving system and a braking system are both realized through hydraulic pressure; the hydro-pneumatic spring cylinder is fixedly connected with the frame, therefore the suitability to an unsmooth road surface and the height adjustability of a finished vehicle are realized; single tyre steering modes and whole vehicle steering modes are diverse; and the structure is simple and the weight of the whole vehicle body is reduced.

Description

technical field

[0001] The invention relates to vehicle technology, in particular to an independent driving unit and a vehicle including the independent driving unit. Background technique

[0002] At present, domestic oil-pneumatic suspensions are widely used in multi-axle super-heavy vehicles, especially on the special chassis of engineering vehicles, but most of them replace traditional leaf springs in the form of oil-pneumatic springs matched with traditional non-disconnected axles. The application of independent oil and gas suspension is mainly concentrated on passenger cars and super-large special vehicles, such as empty dump trucks and large flat-bed beam trucks.

[0003] At present, the main structural forms of the domestic independent oil-pneumatic suspension driving system are: oil-pneumatic spring plus double wishbone plus guide device, and its driving method adopts the traditional mechanical transmission method of the transmission shaft.
