Hydraulic driving system used for brake and composed of motor, deceleration mechanism, screw rod and oil cylinder

Abstract

The invention discloses a hydraulic driving system used for a brake and composed of a motor, a deceleration mechanism, a screw rod and an oil cylinder. The hydraulic driving system comprises the motor, the deceleration mechanism, the screw rod, the oil cylinder, a pressure relay, a power supply control device and an oil pipe. Two ends of the screw rod are connected with an output shaft of the deceleration mechanism of the motor and a piston arranged in the oil cylinder. The oil cylinder is connected to the brake through the oil pipe. The pressure relay is connected with the oil pipe and a power supply control device. The motor, the deceleration mechanism, the screw rod, the oil cylinder, the pressure relay and the power supply control device form a closed-loop negative feedback control system. The hydraulic driving system has the following beneficial effects: a working process is simple with little abrasion; machine parts are not liable to damage; energy consumption time of work is short and considerable electric energy is saved; due to the feature, the screw rod can be self-locked; high voltage is kept without energy consumption; the driving system is almost free from noises and pollution during work; and the overall machine is easy in structure and highly practical and easy for promotion and application.

Description

technical field [0001] The invention relates to a drive system, in particular to a brake hydraulic drive system composed of a motor, a speed reduction mechanism, a screw rod and an oil cylinder. Background technique [0002] At present, there are two types of driving devices for hydraulic brakes used by factories and enterprises: [0003] One is the hydraulic workstation, which requires a long time to maintain pressure and consume electricity, which is also easy to accelerate component damage; [0004] The 2nd, pedal manpower oil supply, the way is backward, and the ability of not establishing high pressure work. [0005] The driving methods of the above hydraulic brakes generally fail to meet the requirements of no pollution, energy saving and environmental protection; thus it is difficult to meet people's production and living needs. Contents of the invention [0006] The object of the present invention is to provide a brake hydraulic drive system composed of a motor, ...

AI Technical Summary

Problems solved by technology

[0003] One is the hydraulic workstation, which requires a long time to maintain pressure and consume electricity, which is also easy to accelerate component damage;

[0004] The second is to supply oil manually by pedaling, which is backward and has no ability to establish high-pressure work.

[0005] The driving methods of the above hydraulic brakes generally do not meet the requirements of no pollution, energy saving and environmental protection; thus it is difficult to meet people's production and living needs
