Description

Untitled Technical Field

[0001] The present invention relates to a wheel hydraulic pump energy-saving device (100), and more particularly to a method in which, when a battery pack power source in a battery pack (123) drives a motor (126) through a controller (125) to drive a universal driving wheel hydraulic energy-saving device (101) in a rotating driving state (99), a hydraulic energy-saving pump (137) structure in an integral hydraulic energy-saving pump device (133) continuously circulates in contact with the ground of a road (113), prompting a built-in piston (223) or a punch (151) or a return (138). When the hydraulic oil in the piston cylinder (229) is in the same structure as the one-way valve input (149) and the one-way valve output (150), it forms an inlet and an outlet working oil liquid. The working oil liquid, the working hydraulic oil, flows to the output interface (203) through the oil channel output oil liquid (194) in the central main shaft (192) and is connected to the high-pressure working oil pipe (119) to drive the hydraulic motor (103) and the planetary gear set (105) and the generator (106). After the hydraulic oil generates electricity, it flows back to the hydraulic oil tank (118) through the return oil pipe (115). Technical Background

[0002] The existing new energy vehicle field has low energy-saving efficiency during driving, and can usually only recover electrical energy during deceleration. Due to the low energy-saving efficiency, the increased mileage after energy saving is almost negligible. As a result of the low energy-saving efficiency, new energy vehicle manufacturers can only increase battery capacity to increase driving range, which further increases the cost of low-priced new energy vehicles.

[0003] Summary of the Invention

[0004] A wheel hydraulic pump energy-saving device (100) of the present technology solves the substantial problem of low energy-saving efficiency of new energy vehicles during driving, and provides a new technology with high energy-saving efficiency during driving of new energy vehicles, which has the remarkable technical progress feature of energy saving.

[0005] The solution of the present method to the above-mentioned technology is a wheel hydraulic pump energy-saving device (100), especially a universal driving wheel hydraulic energy-saving device (101) and a universal driven wheel hydraulic energy-saving device (102). When the hydraulic energy-saving pump device (133) is in a rotating driving state (99), it is in continuous circulation contact with the ground road (113), so that the hydraulic fluid of the hydraulic energy-saving pump (137) generates high-pressure output inside the punch (151) or pumps oil back under the action of the elastic force of the spring (232). When the hydraulic fluid is full, it passes through the one-way valve output (139) and the one-way valve input (149) under the circulation of the hydraulic energy-saving pump (137) to drive the pressure motor (103) and the acceleration planetary gear set (105) and then drives the generator (106) to generate electricity. The generated energy is passed through the rectifier (107) and the voltage stabilizer (108) to charge any battery set as a backup battery in the battery pack (123). When it is needed, the switch is turned on and used in parallel, thereby realizing a technology of high-efficiency and continuous energy recovery.

[0006] The beneficial effect brought by the present invention is that the innovative wheelless hydraulic pump energy-saving device (100) realizes high-efficiency electric energy-saving recovery technology without affecting the driving load, and can be installed in various wheels. It includes the universal driving wheel hydraulic energy-saving pump device (101) and the universal driven wheel hydraulic energy-saving pump device (102) and the universal hub motor hydraulic energy-saving pump device (270) and the crawler hub motor hydraulic energy-saving pump device (331) in the attached figure. The present technology is a wheel hydraulic pump The energy-saving device (100) not only improves energy-saving efficiency, but also, due to its unique structure, when installed on a universal driving wheel hydraulic energy-saving pump device (101), a universal driven wheel hydraulic energy-saving pump device (102), and a universal hub motor hydraulic energy-saving pump device (270), under the buffering action of the hydraulic energy-saving pump (137), the hydraulic energy-saving pump (155), the hydraulic energy-saving pump (274), and the hydraulic energy-saving pump (295), it can replace part of the tire air pressure to prevent tire blowout, thereby improving safety to a certain extent.
