The invention discloses a wheel edge speed reducing device and a brake system thereof, and relates to the technical field of wheel edge speed reduction. The wheel edge speed reducing device comprises a first-grade straight tooth transmission mechanism, a first-grade planet speed reducing mechanism and a second-grade planet speed reducing mechanism; a power input end of the first-grade straight tooth transmission mechanism adopts multiple driving gears; hydraulic motors can supply power to the driving gears; a power output end of the first-grade straight tooth transmission mechanism adopts a driven gear; the driven gear is connected with the first-grade planet speed reducing mechanism, and transfers the power to the first-grade planet speed reducing mechanism; and the first-grade planet speed reducing mechanism is connected with the second-grade planet speed reducing mechanism, and transfers the power to the second-grade planet speed reducing mechanism. The wheel edge speed reducing device uses multiple hydraulic motors to supply the power for common driving; and multiple small hydraulic motors are adopted to replace a large hydraulic motor to drive the wheel edge speed reducing device to operate, so that the problem of difficult model selection of high-horsepower all-hydraulic bulldozer motors is solved, and meanwhile, the production cost can be largely reduced. The invention further proposes a brake system of the wheel edge speed reducing device.
Description
technical field [0001] The invention relates to the technical field of wheel speed reduction, in particular to a wheel speed reduction device and a braking system thereof. Background technique [0002] The current transmission forms of bulldozers mainly include: mechanical transmission, hydraulic transmission, hydrostatic transmission, electric transmission, etc. At present, the mainstream bulldozer manufacturers in the world mainly focus on hydraulic transmission, mechanical transmission and hydrostatic transmission. Full-hydraulic bulldozers are simple in structure, high in transmission efficiency, and the key hydraulic parts can be imported with relatively reliable quality, making it possible to launch high-horsepower bulldozers. [0003] Since the wheel reduction device of the existing bulldozer can only carry one hydraulic motor (that is, only one input port), the output torque of a single motor is limited, so for a high-horsepower full hydraulic bulldozer, a single mot...
