Elastic rubber belt accumulator type loader brake energy regeneration drive

Abstract

The invention discloses an elastic rubber belt energy accumulator type loader braking energy regeneration transmission device, which is high in energy conversion rate, large in energy density, light in weight, simple in structure, and capable of realizing the two-way recovery and two-way braking energy release for advancing and reversing a loader. The transmission device comprises a first elastic rubber belt energy accumulator, a second elastic rubber belt energy accumulator and a gear transmission case. The transmission device is used for accumulating kinetic energy in advancing and reversing braking processes of the loader into the elastic rubber belt energy accumulators in a manner of elastic potential energy of elastic rubber belts, the elastic potential energy accumulated in the elastic rubber belts can be converted into the kinetic energy of the loader in a starting process of the loader, thereby realizing the regeneration of the braking energy and achieving the purposes of reducing the fuel consumption of the loader and reducing the emission.

Description

technical field [0001] The invention relates to a braking energy regeneration transmission device of a loader, more specifically, the invention relates to an elastic rubber belt accumulator type loader braking energy regeneration transmission device. Background technique [0002] With the rapid growth of energy demand and the increasingly scarce oil resources, more and more attention has been paid to energy conservation and emission reduction. Loader is a kind of commonly used construction machinery in engineering construction. Its main working characteristics are short cycle loading cycle, frequent forward, reverse, braking, and starting operations. During the braking process of the loader, the kinetic energy and gravitational potential energy of the loader Both are wasted through the friction of the brakes and the friction between the tires and the ground into heat energy, which not only reduces the service life of the brakes and tires, but also increases fuel consumption...

Problems solved by technology

The electric energy storage type converts the kinetic energy of the vehicle into electric energy through a generator and stores it in a battery or super capacitor, which has the disadvantages of high cost, low braking energy recovery and low energy conversion efficiency; the hydraulic energy storage type uses a hydraulic pump The secondary components such as the vehicle convert the kinetic energy of the vehicle into hydraulic energy and store it in the accumulator, which has the disadvantages of low energy density, large weight, and complex structure; the flywheel energy storage type converts the kinetic energy of the vehicle into the kinetic energy of the high-speed flywheel. This energy storage method has the disadvantages of high cost, high technical difficulty, and immature technology.
