Challenges in the Development of Auto Parts

The commercial vehicle parts industry is highly fragmented, with most companies being newly established individual enterprises. For these small and medium-sized enterprises (SMEs), the initial capital investment is already substantial, and post-production profits are not high. Therefore, it is relatively difficult to encourage them to increase R&D investment. Moreover, the prices of auto parts raw materials have been rising steadily for a certain period, requiring enterprises to allocate a significant portion of their funds to raw materials.

The brake system includes those components

The braking system is a series of special devices that can force the speed of a car to be reduced. The braking system is mainly composed of four parts: energy supply device, control device, transmission device and brake. The main function of the braking system is to slow down or even stop the driving car, keep the speed of the downhill car stable, and keep the stopped car still. The brake system is generally composed of two main parts: the brake operating mechanism and the brake. The braking system can be divided into mechanical, hydraulic, pneumatic, electromagnetic and so on. A braking system that uses more than two energy transmission methods at the same time is called a combined braking system. The braking system is mainly composed of wheel brakes, hydraulic transmission and pneumatic transmission mechanisms. The wheel brake is mainly composed of a rotating part, a fixed part and an adjusting mechanism. The rotating part is a brake drum; the fixed part includes a brake shoe and a brake base plate; the adjusting mechanism is composed of an eccentric support pin and an adjusting cam to adjust the shoe drum gap. The hydraulic brake transmission mechanism is mainly composed of brake pedal, push rod, brake master cylinder, brake wheel cylinder and pipeline. The pneumatic brake transmission mechanism is mainly composed of brake pedal, push rod, brake master valve, air dryer, four-circuit protection valve, brake air chamber and pipeline.

Structural Design of Military Off-road Radial Tire with Large Size, High Speed and Adapt to Ultra-low Pressure Driving

In modern war, the requirements of military off-road vehicle's combat adaptability, mobility and rapid response ability are higher and higher, and the requirements of military off-road vehicle tire performance are also improved accordingly. Traditional bias tires can no longer meet the requirements of military off-road vehicles for tire performance, and the radial requirements of military off-road vehicle tires are becoming more and more urgent. Although the domestic light and medium-sized military off-road tires have been partially realized meridional, due to various reasons, the large-size off-road tires used in domestic heavy-duty military off-road vehicles still adopt the bias structure. This situation seriously restricts the development of China's heavy-duty military off-road vehicles and the actual combat performance of related military equipment. Therefore, according to the requirements of the military, we have developed a large tubeless military off-road radial tire with high speed and ultra-low pressure to meet the performance requirements of the military's heavy-duty military off-road vehicles. The design is introduced as follows.
