The invention relates to a parking system in motor vehicles, particularly to a hydraulic parking system. The hydraulic parking system comprises a motor, a pressurizing pump, an accumulator, an oil storage tank, a parking switch, an electronic control module, a solenoid valve, a locking device and an unlocking device; the motor drives the pressurizing pump to pressurize low-pressure hydraulic oil in the oil storage tank into high-pressure hydraulic oil and the high-pressure hydraulic is stored in the accumulator; after the parking switch is turned on, the electronic control module controls the solenoid valve to input the high-pressure hydraulic oil into the locking device, axles or wheels are locked, and after locking, the electronic control module controls the solenoid valve to discharge the high-pressure hydraulic oil in the locking device into the oil storage tank. After a release switch is turned on, the electronic control module controls the solenoid valve to input the high-pressure hydraulic oil into the unlocking device, the axles or wheels are released, and after releasing, the electronic control module controls the solenoid valve to discharge the high-pressure hydraulic oil into the oil storage tank. The motor drives the pressurizing pump to pressurize the low-pressure hydraulic oil into the high-pressure hydraulic oil periodically and the high-pressure hydraulic is stored in the accumulator. The hydraulic parking system is smart in parking and reduces the product cost.
Description
technical field [0001] The invention relates to a parking system in a motor vehicle, in particular to a hydraulic parking system controlled by a switch. Background technique [0002] The parking system in the prior art mainly contains two ways: the first is to use hands or feet as power, and the axle or wheel is locked with a mechanical device to realize parking; the second is to use electricity as power , use the motor to drive the mechanical device to lock the axle or wheel, so as to realize parking. The first type has the disadvantage of laborious operation during use, while the second type has the disadvantage of complex product structure and high cost. Contents of the invention [0003] The purpose of the present invention is to provide a hydraulic parking system that is lightweight and has low product cost. [0004] The technical solution adopted to realize the purpose of the present invention is: a hydraulic parking system, including a motor, a booster pump, an oi...
