Abstract

The invention belongs to the technical field of gearbox electromagnetic valves, and discloses a gearbox electromagnetic valve. The gearbox electromagnetic valve comprises a direct-drive electromagnetic head, a direct-push valve element and a valve sleeve; multiple liquid inlet windows and multiple matched liquid outlet windows are formed in the valve sleeve; the direct push valve element comprises a mandrel and multiple sealing discs; the multiple sealing discs are arranged on the mandrel at intervals in the axial direction of the mandrel, and a corresponding flow channel is formed between each two adjacent sealing discs; the valve sleeve is fixed onto the direct-drive electromagnetic head, and a first end of the mandrel is connected with a push rod head of the direct-drive electromagnetic head; and the mandrel and the multiple sealing discs are slidingly embedded in the valve sleeve, and are used for opening and closing the multiple liquid inlet windows and the multiple liquid outlet windows. According to the gearbox electromagnetic valve, under a small valve element stroke condition, the large-flow small-flow-resistance electromagnetic valve can be achieved, the load of an electronic oil pump of a cooling system is reduced, the reliability of parts of the cooling system is improved, and energy conservation and emission reduction are achieved.

Description

technical field [0001] The invention relates to the technical field of gearbox solenoid valves, in particular to a gearbox and a solenoid valve thereof. Background technique [0002] Most of the gearbox solenoid valve products are low-flow high-resistance solenoid valves; they mainly meet the pressure oil circuit application requirements of traditional automatic gearboxes and meet the flow requirements under high pressure conditions. Because the traditional gearbox cooling system generally does not use solenoid valves, the existing gearbox solenoid valves are mainly short-stroke electromagnets of 2 to 3mm, which can only form a small flow cross-sectional area when matched with the valve core. Commonly used solenoid valves are small flow high flow resistance solenoid valves. However, the existing gearbox cooling and lubricating system requires a high flow rate under certain working conditions, which leads to a high level of flow resistance, greatly increases the load, and al...
