Hybrid electromagnetic/hydraulic reducer for trucks

Abstract

The invention provides a hybrid magnetoelectric / hydraulic speed reducer for a truck. The upper end of the main gear is arranged in the rear axle housing, and is sequentially connected with the differential gear assembly and the transmission shaft. The lower end of the main gear is connected with the driven gear in the driven gear box, the driven gear is arranged on the driven gear shaft, one end of the driven gear shaft is provided with an electromagnetic deceleration part, and the other end is provided with a hydraulic deceleration part. It uses the working principle of electromagnetic and hydraulic pressure to cooperate with each other to alleviate and reduce the braking performance defects caused by the truck when driving on steep slopes, long slopes and curves at high speed. The braking system of the engine can be used at the same time or separately, so that the truck can safely decelerate in different environments at high speeds, thereby reducing the wear of the braking system, improving its braking performance and safety, economical, practical and effective.

Description

technical field [0001] The invention belongs to the technical field of vehicle brake control, in particular to a hybrid electromagnetic / hydraulic speed reducer for a truck. Background technique [0002] Large and medium-sized trucks operating on the expressway need to use brake pads frequently, especially when decelerating on long slopes, steep slopes, slopes, and curves, the temperature of the brake pads and brake hubs is high, which is easy to cause braking. The rotor is ablated and the brake hub is broken, which affects the braking effect. Therefore, the driver is used to cooling with water, but the water in the water tank is easily blocked, which often fails to achieve the desired effect. [0003] Commonly used engine transmissions, universal joints, and basin gears are prone to wear and tear due to long-term overloading in low-speed gears, and their accessories are expensive and difficult to overhaul, resulting in traffic accidents during long-distance driving of truck...

Problems solved by technology

[0002] Large and medium-sized trucks operating on the expressway need to use brake pads frequently, especially when decelerating on long slopes, steep slopes, slopes, and curves, the temperature of the brake pads and brake hubs is high, which is easy to cause braking. Rotor ablation, brake hub rupture, affect the braking effect

Therefore, the driver is used to cooling with water, but the water in the water tank is easy to block, which often does not achieve the desired effect.

[0003] Commonly used engine transmissions, universal joints, and basin gears are prone to wear and tear due to long-term overloading in low-speed gears, and their accessories are expensive and difficult to overhaul, resulting in traffic accidents during long-distance driving of trucks, affecting safety and transportation. benefit

[0004] The existing automobile reducer relies on the low-speed operation of the engine to control the air intake of the engine. When a valve is used to limit the intake air of the engine, the engine cannot run at high speed. When a valve is installed in the exhaust pipe , it prevents the engine from generating little or no exhaust gas. These two methods can achieve the purpose of deceleration, but it is easy to cause the wear of the engine cylinder liner and piston ring, which will cause the engine to generate a higher temperature, thereby affecting the performance of the engine. , seriously damage mechanical components such as universal joints and basin teeth, resulting in traffic accidents
