Double-driving system of concrete mixer carrier vehicle

Abstract

The invention relates to a double-driving system of a concrete mixer carrier vehicle The double-driving system of the concrete mixer carrier vehicle comprises a vehicle frame; a front steering assembly is arranged in front side of the vehicle frame; a steering execution assembly is arranged under the vehicle frame; a back driving assembly is arranged on the back side of the vehicle frame; the back driving assembly is arranged inside a back cab; the front steering assembly comprises a front steering wheel, a first front steering support, a second front steering support and a full hydraulic pressure steering device; the steering execution assembly comprises a steering power cylinder assembly with a connector, a steering transverse pull rod assembly, an oil cylinder seat, a right bending arm, a left bending arm, a rocking arm seat, a rocking arm, a copper sleeve and a straight-through type pressure injection oil cup; the back driving assembly comprises an expanded cab, an auxiliary support seat, a fixing frame, a pedal fixing seat, a cab bottom plate and a chair seat. The double-driving system of the concrete mixer carrier vehicle realizes two-direction driving through switching between front driving and back driving, solves a problem that the vehicle is hard to turn around in a narrow roadway, solves a problem that vehicle collision happens due to a poor reversing vision and improves a phenomenon that original mechanical steering is labor-consuming.

Description

technical field [0001] The invention relates to a double-driving system, in particular to a double-driving system for a concrete mixer truck. Background technique [0002] Concrete mixer truck or mixer truck is a special truck used to transport ready-mixed concrete for construction; because of its shape, it is also often called a snail truck. The truck is equipped with a cylindrical mixing drum to carry the mixed concrete, and the mixing drum will always be kept rotating during transportation to ensure that the carried concrete will not solidify. After the concrete is delivered, the inside of the mixing drum is usually washed with water to prevent the hardened concrete from taking up space. In the prior art, the concrete mixer trucks used are all single-cab control systems, and the cab is set at the left front of the vehicle. Due to the limitation of the width of the roadway and the U-turn of the vehicle, the vehicle can only reverse and leave, and the sight of the roadway ...

Problems solved by technology

In the prior art, the concrete mixer trucks used are all single-cab control systems, and the cab is set at the left front of the vehicle. Due to the limitation of the width of the roadway and the U-turn of the vehicle, the vehicle can only reverse and leave, and the sight of the roadway is blocked. problem, resulting in frequent bumps when vehicles leave the roadway, reducing the scope of use
