Embodiment

[0039] A quantitative open-type hydraulic drive system of an off-road scissor aerial work platform includes a front drive, a rear drive, two quantitative pumps and a hydraulic control system.

[0040] Both the front drive and the rear drive are provided with two hydraulic drive wheels, including a front drive left wheel, a front drive right wheel, a rear drive left wheel and a rear drive right wheel;

[0041] Four driving modes can be controlled in the hydraulic control system, including:

[0042] 1). Gear I forward / reverse drive mode: This gear only achieves the lowest speed. It can be seen that the hydraulic oil of 1 component is respectively led to the four hydraulic drive wheels, so the theoretical distribution of each hydraulic drive wheel is 1 / 4 component;

[0043] 2). II gear forward / reverse drive mode: In this gear, the solenoid valve controls the on-off of the oil circuit, and then controls the on-off of the hydraulic control valve to realize the oil circuit on-off o...

Abstract

The invention discloses a quantitative open hydraulic drive system of an off-road scissors fork high-altitude operation platform, which comprises a front drive, a rear drive, two quantitative pumps and a hydraulic control system. Each of the front and rear drives is provided with two hydraulic driving wheels, comprising a front left wheel, a front right wheel, a rear left wheel and a rear right wheel; four drive modes of disposable control in the hydraulic control system are I-gear forward / reverse drive mode, II-gear forward / reverse drive mode, III-gear forward / reverse drive mode and differential forward / reverse drive mode. The quantitative open hydraulic drive system of an off-road scissors fork high-altitude operation platform realizes the four-wheel differential lock function rarely available in the existing market, including the central differential, the front axle differential, and the rear axle differential function, which greatly reduces the equipment manufacturing cost.

Description

technical field [0001] The invention relates to the technical field of hydraulic travel drive of an aerial work platform and four-wheel drive differential drive, in particular to a quantitative open hydraulic drive system of an off-road scissor aerial work platform. The mobile aerial work platform can adapt to more complex and harsher road conditions, and at the same time, the cost of purchase, maintenance and repair is low, so that its economic performance cannot be ignored. Background technique [0002] Aerial work platforms are mobile operating equipment that serve high-altitude operations, equipment installation, and maintenance in various industries. Products related to aerial work platforms mainly include: scissor-type aerial work platforms, vehicle-mounted aerial work platforms, articulating-arm aerial work platforms, self-propelled aerial work platforms, aluminum alloy aerial work platforms, and cylinder-type aerial work platforms. . [0003] The hot-selling off-ro...
