Embodiment 1

[0042] Loaders generally have three gears, including two forward gears and one reverse gear, and the speed of the second forward gear > the speed of the reverse gear > the speed of the first forward gear. We will describe the matching process based on this situation.

[0043] Such as figure 1 As shown, wheel 1, rear axle and wheel reducer 2, engine 3, steering pump 4, working pump 5, hydraulic torque converter 6, planetary gearbox 7, low pressure accumulator 8, parking brake 9, million Knuckle 10, accumulator 11, brake valve 12, power coupler 13, controller 14, pump motor 15, caliper brake 16, front axle and wheel reducer 17 is a parallel hydraulic hybrid loader When the loader is running normally, the power of the engine 3 is transmitted to the steering pump 4, the working pump 5 and the hydraulic torque converter 6 respectively, and the power of the hydraulic torque converter 6 is transmitted to the planetary gearbox 7, and then through The front axle and wheel reducer 17 a...

Abstract

The invention relates to a parameter matching method for key components in a loading machine braking energy recovery and regeneration system. The parameter matching method comprises parallel type hybrid power loading machine hydraulic pump motor displacement matching, power coupler transmission ratio matching and energy accumulator volume matching. The method comprises the following steps that 1, the hydraulic pump motor optional displacement and the coupling position of the braking energy recovery and regeneration system and an original loading machine transmission system are determined before the parameter matching; 2, the displacement of the hydraulic pump motor is determined; 3, the power coupler transmission ratio is configured; and 4, energy accumulator volume matching is conducted. The parameter matching method for the key components in the loading machine braking energy recovery and regeneration system provides a practical and simple method for key components parameter matching of the parallel type hybrid power loading machine.

Description

technical field [0001] The invention relates to a design method of a braking energy recovery and regeneration system of a hybrid power loader, in particular to a parameter matching method for key components in the braking energy recovery and regeneration system of a parallel hybrid power loader, which belongs to the technical field of engineering machinery. Background technique [0002] Construction machinery is a kind of engineering and construction machinery products that are widely used. With the continuous increase in the number of construction machinery, the energy consumed by a large number of construction machinery and the pollutants discharged have a serious impact on the environment. Energy-saving and efficient new construction machinery products have become the research and development goals of construction machinery at home and abroad. [0003] During the operation of construction machinery, the mass and inertia of the working device with load are large, and most...
