Abstract

The invention discloses a manual and electric integrated hydraulic brake pump for a tractor. The manual and electric integrated hydraulic brake pump for the tractor comprises a brake pump shell, and while industrial problems of tractors and engineering machinery are solved, the universal manual and electric integrated hydraulic brake pump mechanism is developed comprehensively. On the basis of a traditional brake pump, an electric control function is added, follow-up power enhancement is implemented, manual control and electric control do not interfere to each other, and the problems are solved. The cost performance is high. During manual control intervention, manual control can be carried out without any transformation, and electrical assistance is not required. When a vehicle requires tostop in an emergency event, the system is the same as a traditional brake system.

Description

technical field [0001] The invention relates to the fields of agricultural machinery and engineering vehicles, in particular to a flashlight integrated hydraulic brake pump for tractors. Background technique [0002] my country is a big agricultural country and also a big agricultural machinery country. The tractor and construction machinery industry has a certain gap with western developed countries in terms of automation, intelligence and humanization. At present, tractors and construction machinery brake systems are generally controlled by mechanical force (manpower). The operation of the operator is heavy, and the operation of tractors with more than medium power cannot meet the requirements. Although some models and manufacturers install booster devices, the cost performance is relatively poor, and the structure adopted by the existing models cannot realize electro-hydraulic control. With the improvement of the degree of mechanization, the power of tractors and construct...
